This was another tough year for the amateur (or even professional) prognosticators for NCAA Men’s Basketball.  Once more there was a record number of brackets filled out (22,114,630 brackets).  Once more all the perfect brackets have been busted after the first weekend.  The two largest predictions that failed were #6 BYU’s loss to #11 Duquesne (57–71) which broke 9,352,798 brackets and #8 Mississippi State’s loss to #9 Michigan State (51–69) which broke 9,298,147 brackets.  I my favor, I predicted both games correctly.  The two biggest upsets were #3 Kentucky losing to #14 Oakland (76–80) and #4 Auburn losing to #13 Yale (76–78).  I got both games wrong.  There were also two classic #5 to #12 losses, as Wisconsin lost to James Madison (61–72) and Saint Mary’s lost to Grand Canyon (66–75).  I failed to pick either of the upsets and the Cinderella teams both lost in the second round.  The other scare came in the second round as #9 Texas A&M took #1 Houston to overtime before bowing 95–100.  Most of the 48 games proved entertaining to watch.

When I looked online, I found the bigger news came out of the NCAA Women’s Basketball.  Iowa Hawkeyes guard Caitlin Clark became the NCAA’s Division-I all-time leading scorer in basketball passing Hall of Famer “Pistol” Pete Maravich in a win over the Ohio State Buckeyes on March 3rd.  Clark had already eclipsed the NCAA women’s record of 3,397 points set by Kelsey Plum at Washington (2013-17).  Former Kansas star Lynette Woodard held the women’s major college basketball record (i.e., prior to NCAA) with 3,649 points (1978-81).  Clark entered the final regular season game needing 18 points to pass Maravich for the all-time mark of 3,667 points. She set the record with a pair of free throws in the final seconds of the first half and finished the game with 35 points, 9 assists, and 6 rebounds as No. 6 Iowa beat No. 2 Ohio State 93-83.  That gave Clark a career total of 3,685 points.  Tickets for a Clark game is one of the hottest commodities in sports.

I guess you could say the prognosticators were better this year than they were in 2023.  Last year there were 20,056,273 brackets filled and all had fallen by the second night of the first round.  At least the extra 2 million brackets filled in 2024 kept the predictors in the mix until the second round.  On the women’s side the predictors did only slightly better.  Of the 3,250,647 brackets filled all but 11 had fallen going into the final day of round 2.  The second round saw the prognosticators continue to struggle and entering the Women’s Sweet 16 there are only three perfect brackets remaining.  No one has ever predicted a perfect bracket (men’s or women’s) , but Gregg Nigl from Columbus, Ohio, has the verified bracket closest to perfection in 2019.  Nigl correctly guessed the first 49 games of the men’s tournament until #3 ranked Purdue defeated #2 Tennessee in the Sweet 16.  The NCAA said the odds of a perfect 63-game bracket are 1 in 9,223,372,036,854,775,808 (approximately 1 in 9.2 quintillion).

THOUGHTS:  I have found the progression over the last years interesting on how ESPN handles both basketball tournament brackets.  Two years ago, the Women’s programs made a push to be included under the umbrella of March Madness and that happened last year.  After no perfect brackets again last year (or ever), this year ESPN introduced the 2nd Shot Bracket for both men and women that allows starts over beginning with the Sweet 16 tournament games (32 teams) with the possibility of a greatly reduced cash prize.  I filled out five more brackets but will probably not get any closer than I did with the 10 original brackets I completed.  I have learned that reality is not being pessimistic.  It is good to see the rise of women’s sports as we strive for parity.  Sports (amateur, college, pro) may be driven by money and advertising dollars, but it is the “love of the game” that still inspires young participants.  Act for all.  Change is coming and it starts with you.

Michigan Shipwreck Research Association

On the back of today’s local newspaper was a USA Today article on the number of shipwrecks found in Lake Michigan last year.  There are usually two or three shipwrecks found a year, and the record was four in 2016.  The Wisconsin Historical Society said 13 new shipwrecks were discovered in Lake Superior last year.  Tamara Thomsen, maritime archeologist, said the discoveries were a blend of sand movement and awareness of who to contact.  Water levels in the Great lakes fluctuate from year to year, and in lake Michigan the difference between record high and low water levels is more than 6 feet (1.8 m).  As water levels rise the sand bars drift towards land and when they fall, they move farther into the lake, covering and uncovering the shipwrecks.  There are 36 shipwrecks in the Wisconsin Shipwreck Coast National Marine Sanctuary, which covers over 900 miles² (2,331 km²).  The title helps direct resources to facilitate scientific research, tourism, and education.    

When I looked online, I found the Great Lakes have provided transportation for the area’s inhabitants for 1000’s of years.  Vessels from canoes to car ferries and steamers to modern ore boats have sailed these “inland seas”, and unknown numbers remain settled in watery graves at the bottom of the lakes.    An estimated 6,000 vessels were lost on the Great Lakes with approximately 1,500 of these ships located in Michigan waters.  They range from shallow water to the deepest reaches of Michigan’s 38,000 square miles of the Great Lakes bottomlands.  Michigan’s history can be traced by the material records of its shipwrecks.  The shipwrecks are a wood and steel chronicle of the history of naval architecture on the lakes and pilings of thousands of abandoned docks tell of a time when transport by water was as important as by land.  The cold fresh water of the Great Lakes keeps wrecks exceptionally well preserved even after decades underwater.  Skin and scuba divers from across the US come to explore these preserved shipwrecks. 

Lake Michigan is home to countless shipwrecks, and most of them will never be seen by people up close, let alone explored.  There are a few that met their watery graves not too far from the shoreline, and that means you do not need fancy equipment to see some of the state’s water-bound history up close.  An online article in today’s Fox 17 News suggested the shores of Lake Michigan could be an alternative to those of the Florida Coast for Spring Break enthusiasts.  The article highlighted 6 easy to find and explore shipwrecks and provided a nautical map of dozens more.  Not all shipwrecks in Lake Michigan are easy to see, including the steam barge Milwaukee.  The shipwreck’s location was a mystery until The Michigan Shipwreck Research Association (MSRA) found it last summer over 300 feet (91 m) below the surface of Lake Michigan.  A robotic video of the dramatically intact ship is on Facebook – X (formerly Twitter) – Instagram – YouTube.  Enjoy!

THOUGHTS:  Special care must be taken to ensure the shipwrecks remain for generations to come. Protecting underwater cultural resources preserves them as an element of our history and for the enjoyment of generations to come.  Sport divers, dive clubs, and other dive related organizations requested the Michigan legislature to pass a law that preserves and protects these resources.  Part 761, Aboriginal Records and Antiquities, 1994 PA 451 as amended, is administered jointly by the Michigan Department of Environmental Quality and Department of State.  This law “authorizes preserving abandoned property (shipwrecks, etc.) on the bottomlands of the Great Lakes, designating underwater preserves, issuing salvage permits when appropriate, and for fines and penalties for illegally removing, altering, or destroying artifacts.”  The law does not restrict searching for, diving on, or photographing shipwrecks.  To paraphrase on adage, “Take only photographs, leave only air bubbles.”  Act for all.  Change is coming and it starts with you.

It is appropriate that on the first day of spring I managed to push ahead with the planting for my container garden.  When I first read the article on January planting, I was skeptical.  That meant I was 10 to 12 weeks prior to the last frost (April 15 for zone 7).  I started planning and managed to get in my 8 to 10 weeks inside seedlings.  Several weeks later I replanted both the red onions and artichokes because they never took, along with (mostly) tomatoes in for the 6 week seedlings.  I was under the weather when the 4 week seedlings needed to be planted, but as of today I am caught up.  That means I now have 20 seedling plants in three inch pots, 40 new seedling sets under my grow lights, and 10 to 15 others in stages between, all sharing space among Melissa’s succulents on the glass porch.  Sadly, most “others” are the red onion seedlings.  I can get them to sprout, but they do not seem to get far beyond that stage.  I planted five bunch onions as part of today’s forty (I still hope for onions).  The remainder of my seed should be planted directly into the ground after the last frost date.  I will probably plant more onions directly in the ground and try some onion sets as well.  I may not have a green thumb for onions, but I am persistent.

When I looked online, I found both green thumb and green fingers have been common expressions in England and the US for well over a century.  The Oxford English Dictionary cites the use of green fingers as early as 1906 in the novel The Misses Make-Believe by Mary Stuart Boyd.  Green thumb can be pinpointed to a 1937 Ironwood Daily Globe newspaper article, which described the phrase as “horticultural slang.”  Some believe the origin comes from the result of handling potted plants, which can often have green algae on the underside that coats hands.  Others point to a (likely apocryphal) story about King Edward I and his love of green peas.  The peas were shelled by his servant workers, and one would be honored for doing the most work and having the greenest thumb.  Plants contain chlorophyll, and the green pigment can discolor your hands.  However the phrase was cultivated, it caught on in the 1940’s when wartime Britain enjoyed a popular gardening radio show titled, In Your Garden, hosted by C.H. Middleton that made use of both green thumb and green fingers. 

Most of the online gardening sites tout their ability to transform you from a beginner into someone with a green thumb.  Most will also tell what products you need to buy (often from them) to ensure a bountiful crop.  I cannot fault these sites, because they are the ones I have been pouring over for the last two years to enhance my own container garden.  This has taken me from 5-gallon paint buckets purchased from the hardware store (or lying out back the shed), to grow bags designed to provide self-pruning roots systems, to the metal raised beds employing Hügelkultur that are being prepped in my yard this spring.  Each experience has given me insight into the complexities of gardening.  A green thumb now refers to someone who can seemingly effortlessly grow a wide variety of plants.  This also implies extensive knowledge and experience, and proof can be found in the beds and gardens produced.  I would say I have yet to reach green thumb status.    

THOUGHTS:  Melissa’s mom was known for her green thumb before she became too il to take care of her garden.  The house still shows signs of the hook and chains she used for the hanging baskets to grace the underside of the eaves and the self-watering system is still functional in several areas.  Loki is trying his best to remove it for us.  I asked Melissa what made her mom good at growing things, and she responded she spent 3 to 4 hours a day in the yard.  That implied I could have a green thumb if I was willing to put in the work.  That was not the easy answer I was looking for.  Gardening is like any skill, the more time and effort you spend the better you get.  You do not get to be an expert by merely claiming you know what to do.  Act for all.  Change is coming and it starts with you.

March 20, 2024

On the back page of the front section of my local newspaper last week I found a USA Today article on a tiny fish that roars.  While being one of the smallest fish, it can produce sounds as loud as a jet engine, a new study says.  The species was only discovered three years ago and live in shallow streams in Myanmar.  They are no more than 12 millimeters long and have a “unique sound-generating” organ that can make noises of more than 140 decibels, an international research team said in a news release Tuesday.  The researchers used high-speed video recordings, microcomputed tomography, and gene expression analysis to show that males of the species have a “special sound-generating apparatus” that includes a drumming cartilage, a specialized rib, and a fatigue-resistant muscle.  To make noise, the fish hits the drumming cartilage against its swim bladder (gas-filled cavity used to control buoyancy) to produce a rapid pulse in high and low frequencies.  The study’s author Ralf Britz, an ichthyologist at the Senckenberg Natural History Collections in Dresden, Germany, said, “We assume that the competition between the males in this visually restrictive environment contributed to the development of the special mechanism for acoustic communication.”  According to the study, Danionella cerebrum is the only fish using repeated unilateral muscle contractions for sound production.

When I looked online, I found Danionella cerebrum is a cyprinid (carps and minnows) fish species first reported in 2021 from low altitude streams on the southern and eastern slopes of the Bago Yoma Mountain range in Myanmar.  It was erroneously identified as Danionella translucida due to the close resemblance and similar geographical distribution of the two species.  Adult fish of the species measure only 1/2 inch (10 to 13.5 mm) in size and have a brain volume of just 0.6 mm3, the smallest known adult vertebrate brain.  Because of its miniature size, wide behavioral repertoire, and optical translucency that persists into adulthood, the cerebrum holds great promise for non-invasive whole-brain imaging analyses with single cell resolution in an adult vertebrate.  This is beginning to emerge as a novel important model system in current neuroscience research.

Although large animals are generally more capable of making louder noises than small animals, certain small species can be unexpectedly noisy.  The three species of Elephant (African bush, Loxodonta Africana; African forest, Loxodonta cyclotis; and Asian, Elephas maximus), can produce noise of up to 125 decibels with their trunks, but the tiny snapping shrimp (family, Alpheidae) uses its claws to generate a popping sound of up to 250 decibels.  Other small animals capable of loud noises are the flightless kakapo (Strigops habroptila), whose mating calls can reach 130 decibels, and the male plainfin midshipman fish (Porichthys notatus), which can attract females with an “audible vibrato” of about 100 hertz and 130 decibels.  Fish are generally considered to be relatively quiet members of the animal kingdom.  Danionella cerebrum is the exception to the rule.

THOUGHTS:  Danionella cerebrum makes noise to help them find each other.  As a boy I was always told I had to be quiet when I was fishing, or I would scare the fish away.  I was skeptical but would move several yards down the shore from the adult I was fishing with if I wanted to make noise.  It turns out fish do hear sounds underwater, but depending on what those sounds are can be either attracted or scared off by the noise.  Case in point are the many poppers and rattlers that prove deadly attracting and enticing fish to bite.  While above surface conversation may seem to travel, especially at night, they do not disseminate well below the surface.  I still try and be quiet even as an adult.  Part of fishing is the solitude.  Act for all.  Change is coming and it starts with you.

Yesterday’s NY Times newsfeed ran an article about a pet named Albert that had been removed from his owner’s home.  The New York State Department of Environmental Conservation (DEC) removed Albert on Wednesday after it determined that he was being kept there illegally.  The department said the pet owner had built an addition to his house where Albert lived in an in-ground swimming pool.  The agency said the owner had allowed people, including children, to be in the pool with Albert, who is blind in both eyes and has spinal injuries.  Albert was 11 feet (3.4 m) long, 750 pounds (340 kg) and 34 years old.  Until this week, Albert had lived in the pool house in Hamburg, NY, about 13 miles south of Buffalo.  According to the department, it is illegal to own an alligator in New York unless you have a license, and those licenses are for “scientific, educational, exhibition, zoological, or propagation purposes”.  The alligator’s name was Albert Edward.

When I looked online, I found an alligator, or a gator, is a large reptile in the genus Alligator of the family Alligatoridae of the order Crocodilia.  The only two extant species are the American alligator (Alligator mississippiensis) and the Chinese alligator (Alligator sinensis), although several extinct species of alligator are known from fossil remains.  Alligators first appeared during the Oligocene epoch about 37 million years ago.  The name “alligator” is likely an anglicized form of the Spanish term for “the lizard” (el lagarto) which early Spanish explorers in Florida called the alligator.  An average adult American alligator’s weight is 790 pounds (360 kg) and length is 13 feet (4 m), but they sometimes grow to 14 feet (4.4 m) and weigh over 990 pounds (450 kg).  The largest alligator ever recorded was found in Louisiana and measured 19.2 feet (5.84 m).  The Chinese alligator is smaller, rarely exceeding 7 feet (2.1 m) and males rarely weigh over 100 pounds (45 kg).  The average lifespan for an alligator has never been measured, but one of the oldest recorded alligators was Saturn, who was hatched in 1936 in Mississippi and spent a decade in Germany before being transferred to the Moscow Zoo.  Saturn died at the age of 84 on 22 May 2020. 

The DEC said Albert’s owner, Tony Cavallaro, had a license for the alligator that expired in 2021.  Cavallaro said that while visitors to his home did sometimes take pictures with Albert, they never swam with him or rode him.  “I did everything by the book the whole time,” Cavallaro said. “They changed the rules, and I should be grandfathered in.”  The DEC adopted new regulations for owning alligators and other dangerous animals in 2020 and informed Cavallaro of the changes and required updates to the alligator’s enclosure.  Cavallaro said that he would have had to spend $15,000 for a fence around his yard and even more for zoo insurance when Albert was already covered by his personal insurance.  Cavallaro sent paperwork to the department, but the agency said it was not sufficient.  The 750-pound alligator was taken to a licensed caretaker until he could be transported to a permanent facility.  Cavallaro filed a petition to bring Albert home which has drawn more than 100,000 signatures.  The petition claimed the DEC “brought at least 20 or more agents to my house in full body armor and guns treating me like a criminal.”  “He was scared,” Cavallaro said.

THOUGHTS:  Cavallaro is a reptile enthusiast and bought the newborn alligator at a reptile show in 1990.  At one point he owned over 100 reptiles, but caring for them became too much work and he gave up the last of his snakes 16 years ago.  Since then, it has just been him and Albert, until now.  I think it may not be Albert who is scared.  While Cavallaro’s love for an alligator may not be the norm, the DEC’s reaction of changing the rules and enforcing compliance is.  Acting different should not be treated as aberrant.  Act for all.  Change is coming and it starts with you.

Hidden inside the back section of today’s local newspaper was a USA Today article on a recent study on the life cycles of different species of whales.  A paper published Wednesday in the journal Nature looked at 32 whale species, five of which undergo menopause.  The findings suggest menopause gives an evolutionary advantage to grandmother whales’ grandchildren.  This is a unique insight because very few groups of animals experience menopause.  In five species of toothed whales, orca (Orcinus orca), beluga whales (Delphinapterus leucas), narwhals (Monodon monoceros), short-finned pilot whales (Globicephala macrorhynchus), and false killer whales (Pseudorca crassidens), the findings suggest menopause evolved so grandmothers could help their daughters’ offspring, while not competing with the younger female for mates.  While whales may seem biologically distant from humans, there are important similarities.  Both are mammals, both are long-lived, and both live in family and social groups that help each other.  Humans are the only land-based animals that go through menopause, and the findings could offer clues about why humans evolved the trait.

When I looked online, I found Menopause, also known as the climacteric, is the time when menstrual periods permanently stop marking the end of reproduction.  Menopause in humans typically occurs between the ages of 45 and 55, but timing varies.  Menopause is a natural change but can occur earlier if you smoke tobacco, have surgery to remove both ovaries, or undergo some chemotherapy.  Menopause happens physiologically due to a decrease in estrogen and progesterone.  Prior to menopause, a woman’s periods become irregular, and they often experience hot flashes (shivering and night sweats) that can recur for four to five years.  The physical consequences of menopause include bone loss, increased abdominal fat, and adverse changes in a woman’s cholesterol profile and vascular function.  These changes predispose postmenopausal women to increased risks of bone loss (osteoporosis) and bone fracture, and of diabetes and cardiovascular disease.  Menopause in humans has long been a biological enigma, but the study of whales is providing scientists with a better understanding of human biology.

The researchers’ findings also support what is known as “the grandmother hypothesis”, which states menopause is evolutionarily useful.  Older women who are no longer able to have children can focus on supporting their children and grandchildren.  This means their family lines are more likely to survive, which has the same effect as having more children.  “What we showed is that species with menopause have a much longer time spent to live with their grand offspring, giving them many more opportunities for intergenerational health due to their long life,” said Samuel Ellis, an expert in human social behavior at the University of Exeter.  The live-long hypothesis suggests menopause increased total life span, but not how long a woman could have children.  That leads to a prediction that species with menopause would live longer but have the same reproductive life span as species without menopause.  This appears to be exactly what humans did.  The study does not prove the grandmother hypothesis is the reason for menopause in women, but it does lay out the evidence.

THOUGHTS:  Thankfully (for me), the whale study does not reflect human male life spans.  In Orca populations females live into their 60’s and 70’s, but males are all dead by 40.  No one knows why human females undergo menopause even though both sexes live to be approximately the same ages.  The difference may be that for humans both grandmothers and grandfathers contribute to the well-being of their children and grandchildren.  This is an evolutionary change human dads and granddads may want to reflect on.  Act for all.  Change is coming and it starts with you.

Two years ago, I mentioned how the Hyacinth (Hyacinthus orientalis) planted by Melissa’s mom had finally returned to the mailbox flower bed.  The hyacinth had been dormant for over a decade.  When they first sprouted, Melissa did not look at them and said they must be one of the many weeds that thrive in the bed.  Since they were weeds, I had torn them up and threw them away.  When they arrived two years ago, I was lax and allowed them to grow.  When they sprouted again this year, I once more let them grow on their own.  They have produced a lush carpet of leaves that have filled the entire bed and the flowers have bloomed this week.  I am always looking for ways to help the pollinators and the hyacinth appear to provide a good source of nectar.  When I went out to get the mail this morning the bed was swarming with bees.     

When I looked online, I found honeybees (also spelled honey bees) are a eusocial flying insects within the genus Apis of the bee clade, all native to mainland Afro-Eurasia.  Bees spread naturally throughout Africa and Eurasia, and humans were responsible for the wider distribution, introducing multiple subspecies into South America (early 16th century), North America (early 17th century), and Australia (early 19th century).  Honeybees are known for their construction nests from wax to hold their large colonies and their surplus production and storage of honey.  Their hives are a prized foraging target for honey badgers (Mellivora capensis), bears (family Ursidae) and human hunter-gatherers.  Only 8 surviving species of honeybees are recognized (with 43 subspecies).  Historically 7 to 11 species are recognized.  Honeybees represent only a small fraction of the roughly 20,000 known species of bees.  The best known honeybee is the western honeybee, (Apis mellifera), which was domesticated for honey production and crop pollination.  The only other domesticated bee is the eastern honeybee (Apis cerana), which occurs in South, Southeast, and East Asia.  Only members of the genus Apis are true honeybees, but other types of bees produce and store honey and have been kept by humans for that purpose.

A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower, resulting in fertilization.  Insects are the major pollinators of most plants.  Insect pollinators include all families of bees and most families of aculeate (stinging) wasps, ants, many families of flies, many lepidopterans (butterflies and moths), and many families of beetles.  Bats and birds are the main vertebrate pollinators, but non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants.  Among pollinating birds are hummingbirds (366 species in family, Trochilidae), honeyeaters (186 species in family, Meliphagidae), and sunbirds (151 species in family, Nectariniidae).  These all have long beaks and tend to pollinate deep-throated flowers.  Humans may also carry out artificial pollination.  Western honeybees are often described as essential to human food production and fruits like apples (Malus domestica), blueberries (genus, Vaccinium), and cherries (genus, Prunus), are 90% dependent on pollination by bees, but many crops need no insect pollination at all.

THOUGHTS:  Crops originating in the New World (the Americas) do not rely on honey bees as they are an invasive species, but they do require native pollinators.  However, all pollinators need food and shelter.  Many insect pollinators have a narrow range of plants they can eat.  All pollinators need appropriate nesting sites.  Migratory pollinators require overwintering sites.  During the last 25 years, many species of pollinators have experienced large drops in numbers.  Protecting ecosystems is also protecting our food supply.  Act for all.  Change is coming and it starts with you.

I mentioned Melissa gave me metal raised beds (along with 100’s of seeds) for Christmas.  I planned on putting the beds on the south side of the house where we get the most sun.  Melissa had grown a vegetable garden there and knew it was a viable location.  This would also keep Loki from having direct contact with the beds (he is a digger) and being off the ground would help discourage the critters that have feasted on the melons I tried to grow in my ground beds over the last three years.   I took January to research what to grow in the beds and the best way to fill them.  The simple answer was fill them with compost and place several inches of potting soil on top.  The problem was three of the beds hold around 3 yards³ (2.3 m³) each, and the larger bed is closer to 5 yards³ (3.8 m³).  That is a lot of compost.  As I checked online about filling raised beds, I kept coming across a less expensive method that used wood and yard debris already on hand and was also said to be a better long term method for your vegetables.  This layered approach to filling a raised bed is called hügelkultur.

When I looked online, I found Hügelkultur (German, “mound culture”) is a centuries-old technique of creating mounds of raised garden beds made up of layers of compostable material you already have.  That includes tree limbs, grass clippings, leaf litter, and all sorts of garden debris.  The mounds can sit directly on the surface of the garden or be contained in a raised bed.  A hügelkultur mound consists of layers stacked on top of each other.  The bottom layer is made by placing large chunks of wood on the ground and gradually adding smaller branches and debris as you stack the pile.  Next comes a nitrogen-rich layer of leaves, grass clippings (if the lawn was not sprayed), kitchen scraps, manure, or other organic matter to fill the spaces at the top of the pile.  The third layer adds less desirable subsoil to fill in the holes left in the pile, then 3 to 4 inches (7.5 to 10 cm) of compost, and finally 1 to 2 inches (2.5 to 5 cm) of topsoil.  The different layers break down over time and add nutrients to your soil.  As the wood layer in the base of the bed rots over time it provides spaces for water and nutrients, keeping your garden productive, self-watering, and full of nutrient-rich soil for your plants.  Hügelkultur originated in Germany but is catching on in gardens everywhere.

While I do not have a lot of wood in my suburban yard, I do have several trees that need to be trimmed.  During the pre-Christmas sale season, I found a combination cordless electric leaf-blower and grass trimer along with a cordless chain saw that all use the same 40 volt battery.  These will remove part of my carbon footprint while I take care of my lawn needs.  Everything I read advised against major pruning on my Bradford pear (Pyrus calleryana) until the late winter or early spring as the tree was starting to wake up.  This let me say I was waiting (not procrastinating) to do the work of trimming my tree and using the wood to fill my raised beds via hügelkultur.  I started putting the four beds together in February, laid down the ground cloth for the spaces between the beds early in March, and this week began to trim my trees and fill my beds.  I have more trimming and still need to fill two more beds with debris.  Then comes the compost and soil. 

THOUGHTS:  Using hügelkultur to fill my raised beds sounded like a good idea when I began, and I still think it will be in the long run.  While none of these tasks have been hard, all of them have been tiring and time-consuming.  These tasks all must be done in stages that are dependent on each other.  I need to trim the trees to get the wood for my beds to add compost before I can plant the seeds that have been under my grow lights.  Every subsistence agriculturalist goes through a similar progression to plant their crops every year.  Then it is up to the weather to get a good result.  This is the lesson I hoped to gain from my experience, even knowing I have a safety net (market).  Act for all.  Change is coming and it starts with you.

March 08, 2024

Last December I decided to become a member of the Sierra Club.  I began my academic career hoping to become a wildlife biologist (Inorganic Chemistry did me in) and later worked reviewing Environmental Impact Statements for the State of Utah and was aware of the work being done by the organization.  Last December I received (along with throngs of others) an invitation and decided to become a member.  One of the perks is quarterly copies of Sierra, the club’s official magazine.  I received my Spring issue this morning and one of the first articles addressed the prevalence of animal species normally thought to live only in the wild that reside close to people in rural, suburban, urban, and even inner city locations.  I recalled how the beginning of the pandemic in 2020 resulted in scientists proposing the word “Anthropause” (human pause) to explain the increased activity of urban wildlife as human activity had been curtailed.  In the Sierra article, Bethany Brookshire described how these animals have always lived in our midst as synanthropes, even if we rarely see them.

When I looked online, I found synanthropes (from ancient Greek, “together, with” and “man”) refers to organisms that live near and benefit from humans and their environmental modifications.  This term includes species regarded as pests or weeds but does not include domesticated animals.  Plant synanthropes can be of native origin or of foreign origin and introduced voluntarily or involuntarily.  Animal synanthropes are common in houses, gardens, farms, parks, roadsides, and rubbish dumps.  Examples of animal synanthropes include various insect species (like roaches, order Blattodea) we consider pests along with those we enjoy (like butterflies, lepidopteran suborder Rhopalocera), passerine or perching birds (like house sparrows, Passer domesticus and blue jays, Cyanocitta cristata), and various rodent species.  Among animals the brown rat is one of the most prominent synanthropes and can be found almost anywhere there are people.  As humans continue to encroach on animal habitats raptor birds (like redtail hawk, Buteo jamaicensis) and larger mammalian species (like white-tailed deer, Odocoileus virginianus and coyote, Canis latrans) are also synanthropes.  

Brookshire made the point that knowing we are altering an existing ecosystem is only the first step and the second is working to create avenues for coexistence with our synanthropes.  The red-tailed hawk is a majestic sight as it soars in the sky, perches on power poles, and nests under bridges.  By contrast the brown rat is viewed with disgust as it scurries over trash bins or slinks along alley ways.  While the immediate response may be to place rodenticides to kill the rat population.  However, the hawks and owls’ prey on the dead rats and are in turn poisoned as well.  The New York City Parks (NYCP) department no longer uses rodenticide during hawk breeding season and suggests residents to do the same.  The city uses snare traps and Rat Ice (essentially dry ice), along with pumping carbon monoxide into burrows, to control the unwanted species without harming the birds.  Sunny Carrao, biologist with NYCP, said it is like walking a tightrope trying to manage the synanthropes humans do not want and the charismatic ones we do.  This is made more precarious as they are all connected by the food chain.   

THOUGHTS:  Forgetting we live with synanthropes can have consequences for both them and us.  Encountering a black bear (Ursus americanus) in your yard as happened in our neighborhood last June can cause fear and panic.  Generally large predators stay away or hide from humans but when they are seen we choose whether to live and let live, to control, or to cull.  These decisions are best made in advance and not in the panic that follows a sighting and there are consequences for each path.  Finding ways to co-exist is preferable for synanthropes and for the people who live with their presence.  Act for all.  Change is coming and it starts with you.

Inside the front section of my local newspaper, I found an AP article on how areas around Salt Lake City, Utah, were being inundated by windblown debris.   This debris rolled in over the weekend and blanketed some homes and streets in South Jordan, a suburban Salt Lake City.  Crews were brought on Tuesday to plow, load, and haul the dried carcasses four days after scores of the beachball-sized plants were bounced in by heavy winds.  Dawn Ramsey, South Jordan’s mayor said, “People woke up Saturday morning and it looked like these huge walls had been erected made of tumbleweed,” said. “We had entire streets in some of our neighborhoods completely blocked. They wrapped around homes.”  Saturday’s tumbleweed takeover is not isolated, nor is it a conspiracy by the invasive Russian thistle to conquer the western US.  These occurrences are due to combinations of seasonal wet and dry weather, the death cycle of the tumbleweed plants, and the strong gusts that propel them.  Mayor Ramsey said that three consecutive windy storms in 2021 brought in tumbleweeds to South Jordan, but not like Saturday’s event.  Cleanup was nearly complete by Tuesday afternoon as 13 dumpster loads of tumbleweed had been taken to a landfill.  No damage has been reported.

When I looked online, I found tumbleweed (Salsola tragus), also known as prickly Russian thistle, windwitch, or common saltwort, is a species of flowering plant in the family Amaranthaceae.  In regions of the US, it is the most common and conspicuous species that produces tumbleweed (other species do as well).  The young version of the species may be grazed but then become too spiny and woody to be edible to most wildlife and livestock.  Mature specimens are often more than 39 inches (1 m) in diameter.  As its fruits mature, the seed pod (diaspore) dies, dries, hardens, and detaches from its root.  This detached part of the plant is colloquially called “tumbleweed”.  Once detached, the dry orb will tumble (roll) with the force of the wind.  As the dead structure tumbles, it gradually falls apart, spreading as many as 200,000 seeds across the land.  If the seeds disperse in a wet area they can germinate rapidly.  Tumbleweed has a high tolerance of salinity and can successfully compete with native plants in environments like sea beaches, grassland, desert, or semiarid regions.  Native to Eurasia, Salsola tragus has proven to be highly invasive as an introduced species and rapidly became a common ruderal weed of disturbed habitats throughout the world.  It is believed tumbleweed was introduced into the US by Russian immigrants as a contaminant in flax seed.

Utah is not the only environment to be overcome by tumbleweed.  Mini-storms of tumbleweed swamped the drought-stricken prairie of southern Colorado in 2014, blocking rural roads and irrigation canals, and briefly barricading homes and an elementary school.  Parts of Victorville, California, were nearly buried by the large balls of the dried weeds in 2018.  Tumbleweed is known to damage non-native plants and environments and its highly flammable nature sometimes helps wildfires spread, especially during windy conditions.  An ignited tumbleweed may spread fire across firebreaks and even ignite buildings or structures that it stops against.  Erica Fleishman, of Oregon State University and director of the Oregon Climate Research Institute, noted that little work has been done on how climate change may affect tumbleweed.

THOUGHTS:  Tumbleweeds have become entrenched in western US culture and how many view the Old West.  They also figure prominently in “Tumbling Tumbleweeds,” a song recorded by Sons of the Pioneers in the 1930’s and identify the singer with the drifting tumbleweed rolling through the empty western spaces.  This is yet another immigrant which now defines an iconic age of Americana.  Act for all.  Change is coming and it starts with you.
