Citrus

November 19, 2025

I have been winterizing my garden for the last several weeks.  That means taking down the trellises for storage and removing what is left of the plants.  I mentioned how I tore out the tomato (Solanum lycopersicum) vines in mid-October, resulting in 14 jars of salsa verde.   I did keep three vines on the off chance the fruit would ripen but gave up on them last week.  While I did have several fruits that had begun to ripen, most were solid green.  I was surprised as several more of the green tomatoes have ripened on the counter.  I harvested one head lettuce (Lactuca sativa) that grew, and we ate it as a salad last night.  The one spinach (Spinacia oleracea) that grew will become a wilted spinach salad for tonight along with fried green tomatoes.  I blanched the ripe/partially ripe tomatoes and froze them to make pasta sauce later.  I still have six cabbage (Brassica oleracea) I am holding out for sauerkraut.  They have yet to form a head so they will probably not make it before the frost.  Only about a third of the second crop peas (Pisum sativum) grew and are now producing pods.  We will finish them this week.  This year I am also trying another tact to preserve my citrus trees.

When I went online, I found Citrus is a genus of flowering trees and shrubs in the family Rutaceae that produce fruits.  Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia where indigenous people have used and domesticated various species since ancient times.  Citrus cultivation first spread into Micronesia and Polynesia through the Austronesian expansion (3000 to 1500 BCE), later spread to the Middle East and the Mediterranean (1200 BCE) via the incense trade route, and then from Europe to the Americas.  Citrus fruits are renowned for their fragrant aromas and complex flavor and are among the most popular fruits in cultivation.  The plants tend to hybridize between species making their taxonomy complicated.  The numerous varieties cover a wide range of appearance and fruit flavors.  Many important citrus crops have been developed through extensive hybridization, including oranges (Citrus macroptera), lemons (Citrus limon), grapefruits (Citrus paradisi), and limes (Citrus aurantiifolia) which all have many cultivars.

Two years ago, I purchased two citrus trees (limon and lime) hoping to grow my own fruit.  These were 4 feet (1.3 m) tall, and the seller suggested I might even get a few fruits that first year.  While the lime never fruited, the limon did have one fruit that I used for zest.  I had placed them in pots seated on rolling carriers to move them inside as I did not think they would survive the winter.  It proved impractical to move them indoors, so I bought protective covers to keep out the frost.  Citrus trees are evergreen and keep their foliage year-round, but stress from sudden temperature drops, low light (especially indoors), or lack of humidity can cause them to shed leaves.  When I removed the covers in late winter the leaves and most of the branches were dead.  I thought they had completely died, but they both began to sprout new stems by the spring.  This year I am putting them in the garage to protect them from the bitter cold.  Now to get them some light (grow lamps?).

THOUGHTS: It made more sense why my citrus trees died when I found out they were evergreen.  While some leaves may fall, they still need sunlight, water, and moderate temperatures.  Covering them deprived them of sunlight and never watering them dried them out.  Melissa told me when we return from our trip, she will make room on the sunporch so they can winter with the succulents.  I am hopeful they will continue to thrive under these conditions.  Much like my citrus trees, humans also need the right conditions to survive.  That includes adequate food, safe water, and protection from the elements (clothing and shelter).  A study focusing on low- and middle-income countries suggests 4.4 billion people lack safe drinking water and the WHO found 1 in 4 lack safe access to water.  We need to find another tact.  Act for all.  Change is coming and it starts with you.

Volatile

November 17, 2025

It seems hard to believe that last week I was protecting the pipes in our RV from a hard freeze.  The temps dropped to 28F (-2C) on consecutive nights.  While it did warm up to the mid 40’sF (7C) on both afternoons it was still a cause for concern.  I did not winterize the water lines and tanks since we are still hoping to take a trip around Christmas.  Our mechanic told us the lines in our Sunseeker are contained inside the compartment and there are water heaters to keep the tanks warm.  I turned on the water heater, set the tanks to Arctic mode, and turned the inside furnace to 60F (15.5C), its lowest setting.  After a brief spell, the temperatures warmed again.  Two days later it climbed back to 80F (26.6C) and our unit had survived its first test.  The temps have stayed in the 70’s+F (21+C) this week, although they will dip just as we leave for another extended trip at the end of the week.  While the wildflowers in the front bed did not survive the chill, the clematis (Clematis var. “The President”) on the back fence decided to burst into bloom.  Is it just me or does the weather seem more volatile?

When I went online, I found the weather is becoming more volatile.  This includes rapid temperature swings and increases in atmospheric instability due to a warmer, moister atmosphere.  According to climate scientists and studies global warming is a primary driver, making the atmosphere more unstable and extreme events more common.  Studies show the frequency and intensity of extreme weather are increasing, and this trend is expected to continue.  An increase in low-level moisture content and warmer air temperatures have significantly increased atmospheric instability over the past 40 years.  This makes the weather volatile with more frequent and intense “climate whiplash” or rapid temperature changes, which give little time for adaptation.  This volatility contributes to a rise in extreme events such as record-breaking heatwaves, more intense rainfall, and more powerful storms.  The world’s oceans are at the highest temperatures recorded in the last 1,000 to 2,000 years, which can fuel more extreme weather.  A study in Nature noted rapid intensification rates in the Atlantic have resulted in an increase for hurricanes since 1971.

While most changes to address the volatile nature of the weather require systemic shifts, there are some things individuals can do to prepare.  Pay attention to local weather forecasts and heed warnings for extreme events like flash floods.  Encourage your community to plan for volatility by designing resilient infrastructure will be better equipped to handle extreme events.  Understand your local flood risk and take steps to prepare, as weather patterns are changing.  Lori Peek, director of the Natural Hazards Center at the University of Colorado, said, “Infrastructure is aging in our country and is more vulnerable given the fact that there are just simply . . . more people living in harm’s way.”  This is true for the wildfires of California, the floods of the Midwest, and the hurricanes of the east coast.  None are going to go away on their own.

THOUGHTS: The US is responding to this volatile weather with mass layoffs and cuts to the agencies that study climate and help warn and deal with disasters.  Workers at the Federal Emergency Management Agency, the National Weather Service, and research labs at the National Oceanic Atmospheric Administration and the US Geological Survey are also leaving and taking their expertise with them.  It could take years to make up for this brain drain.  The country needs to plan for worst case scenarios and build infrastructure to lessen the effect.  The dinosaurs did not know the comet was going to strike.  We know but need to act.  Act for all.  Change is coming and it starts with you.

TV

November 13, 2025

The 2021 C class RV we purchased this summer had a TV mounted inside, but it was an older model.  This was a special 40-inch (101.6 cm) RV TV built to withstand the vibrations and temperature changes of being on the road and had a 12V power option that was connected directly to the house batteries for use when not plugged into shore power.  We were told a regular TV might not handle the constant shaking or the temperature and humidity fluctuations.  Melissa did quite a bit of searching online and in the RV Facebook group she frequents and determined a regular smart HDTV would be adequate for our use.  She also checked the dimensions of the cab and found the space would easily accommodate up to a 55-inch (139.7 cm) TV.  We have purchased several TVs over the last several years, including two 70-inch (177.8 cm) screens at the conference center where I was director.  Each time we found the best (or comparable) deals were from the big box store.  Last week I decided it was time to bite the bullet and purchase a new TV.  When I walked into the store, I was confronted with a display featuring a 100-inch (254 cm) screen TV.

When I went online, I found a 100″ TV should be placed in a room with a viewing distance of roughly 8 to 11 feet (2.5 to 3.4 meters) away from the viewers.  The center of the screen should be at eye level when seated, or around 42 inches (105.7 cm) from the floor, and positioned so viewers are facing it directly with minimal glare from windows or lights.  For a more cinematic experience, use the Society of Motion Picture and Television Engineers (SMPTE) or THX (Thanks) recommended 30-to-40-degree field of view, which means sitting closer or about 9.7 to 11.18 feet (2.9 to 3.4 m) away.  Arrange your furniture so that viewers are directly in front of the TV, within a 30-degree angle of the screen and use curtains or blinds to block direct sunlight and position the TV to avoid reflections from lamps or other light sources.  Finally, ensure there is enough space for people to walk around comfortably and to avoid blocking the screen.

It was clear our RV did not have the space to hold the 100-inch screen, let alone the distance away to provide a clear picture.  The 50-inch TV we wanted suggests a range of 4.2 to 6.3 feet (1.3 to 1.9 m) which is perfect for seating in the camper dining area.  The previous owners had removed the bench and table seating and replaced it with fabric covered chairs and ottomans.  We replaced these with a faux leather reclining loveseat that was more comfortable and provided more room for the kids on the floor.  The box store had a variety of other TV sizes, so I walked back to the row of 50-inch TVs. There were three different brands and several levels of picture quality.  After a text discussion with Melissa (she had done the research) I settled on a 50-inch 4K QLED Smart TV that is streaming and Bluetooth ready.  We have determined a way to run a power strip to the TV which will run off the generator if we are off grid (boondocking).  Now all I have to do is install the TV.

THOUGHTS: The THX designation on a smart TV refers to sound quality rather than picture and is an acronym for “Tomlinson Holman’s eXperiment”, a company founded by Tomlinson Holman and George Lucas.  The name is also a nod to the 1971 George Lucus film, THX 1138.  “Thx” is also a common abbreviation for “thanks”, used as a casual way to express gratitude in texting and online communication.  Other common texting abbreviations include LOL (laughing out loud), BRB (be right back), IDK (I don’t know), IMO (in my opinion), FYI (for your information), OMG (oh my God), ASAP (as soon as possible), BTW (by the way), TBH (to be honest), and LMK (let me know).  An acronym is a word formed from the first letters of other words that can be pronounced as a single word.  If you are familiar with the media or field, they make sense.  Language can be a way to both communicate and exclude others.  Act for all.  Change is coming and it starts with you.

Squash

November 12, 2025

Following a second night of hard freeze (28F/-2C or lower for several hours) temps are forecast to be in the 60’sF (15.5+C) and 70’sF (21+C) for the next week or two.  I had removed the sheets covering the last vegetables during the day between the freezes but permanently removed them yesterday as the daytime temps will remain well above freezing until we leave for a trip later in November.  By that time any 2nd crop vegetables that are going to produce fruit will have done so.   I already have a few peas (Pisum sativum), and the cabbage (Brassica oleracea) is beginning to curl into heads.  My garden activity got me motivated to make something with the butternut squash (Cucurbita moschata) I harvested several weeks ago.  The two ways I prefer to eat squash are roasted or in a cream soup.  I had a variety of vegetables in the refrigerator to go along with the squash, so I decided to make both.  

When I went online, I found squash, or Cucurbita (Latin ‘gourd’) is a genus of herbaceous fruits in the gourd family, Cucurbitaceae (also known as cucurbits or cucurbi), native to the Mesoamerica and the Andes.  The five edible species are variously known as squash, pumpkin, or gourd, depending on species, variety, and local jargon.  Other kinds of gourd, called bottle-gourds, are native to Africa and belong to the genus Lagenaria.  These are in the same family and subfamily as Cucurbita but in a different tribe.  The young fruits of bottle gourds are eaten like those of the Cucurbita species while the dried gourds are used as kitchen utensils.  There is debate about the taxonomy of the genus and the number of accepted species varies from 13 to 30.  The five domesticated species are Cucurbita argyrosperma, C. ficifolia, C. maxima, C. moschata, and C. pepo, all of which are called winter squash because the full-grown fruits can be stored for months.  Most squash species are herbaceous vines that grow several meters in length and have tendrils.  The yellow or orange flowers are either female (fruit) or male (pollen).  While botanical fruits, squash are cooked and eaten as vegetables.

I make my squash soup differently than most recipes (surprising, right?).  They suggest roasting squash and onion (Allium cepa) and adding it to a base of chicken broth and cream.  Nutmeg (Myristica fragrans) and sage (Salvia officinalis) then give the soup a sweeter taste.  I begin with roasting but add other vegetables and forego the spices.  Yesterday I roasted a sheet of baby carrots (Daucus carota), green bell peppers (Capsicum annuum), cauliflower (Brassica oleracea), potatoes (Solanum tuberosum), and red onions at 425F (218C) for 20 minutes to let them caramelize.  Next, I placed four small squashes, cut in half and seeded, on a sheet with salt, pepper (Piper nigrum), and olive (Olea europaea) oil.  I added a half cup of water (steam) and roasted them for 45 minutes.  During the last 20 minutes I added the same vegetables (minus the potatoes) to another sheet to roast.  I added the vegetables to the cream and broth base and used a hand mixer to puree the vegetables.  Melissa likes chunkier soup, so I did not make smooth puree.  I tasted the soup, and it seemed bland.  Melissa suggested more salt (tried to be low sodium) and black pepper (Piper nigrum) along with red pepper (Capsicum annuum) flakes.  That made it.

THOUGHTS: Melissa and I enjoyed the squash soup yesterday.  I kept some of the extra in a bowl for later this week and the rest went into a freezer bag, along with the two freezer bags of first batch roasted vegetables.  These went into the freezer for later meals.  Canning and freezing have become my go-to for excess produce and even leftovers.  While I enjoy the dishes I make, they are often too much for the two of us.  I also share as much as I am able with neighbors or the local food bank (produce).  Residential and community gardens can make a difference for those who face food insecurity.  Act for all.  Change is coming and it starts with you.

Iguana

November 11, 2025

Credit…Daniel Mulcahy

The Morning Read of the NY Times feed included an article on a possible reprieve for a previously invasive reptile species.  Biologists say DNA evidence proves the lizard landed on Clarion Island nearly half a million years ago, long before any humans might have transported them from the mainland.  Researchers reported the discovery last month in the journal Ecology and Evolution, and the finding means that the animals should be able to continue living on Clarion Island, a remote, mostly uninhabited Mexican archipelago in the Pacific Ocean.  There are around 100 iguanas there, and scientists and locals alike assumed that they had been introduced by humans in the late 20th century because they had gone unmentioned in prior accounts of the island’s fauna.  “It was all speculative that they were introduced — no one ever tested it,” said Daniel Mulcahy, an evolutionary biologist at the Museum of Natural History in Berlin who is an author of the new study.  The government was planning to exterminate the invaders to protect island’s delicate ecosystem.  Mulcahy and his colleagues compared mitochondrial DNA, passed down maternally, from the Clarion iguanas and the mainland spiny-tailed iguanas and found a 1.5 % difference in their DNA.  That meant these spiny-tailed iguana are genetically distinct and could not be recent invaders.

When I went online, I found the spiny-tailed iguana (Ctenosaura pectinata) is a species of is a species of iguanid lizard found in eastern Mexico and extreme western Guatemala.  This iguana has distinctive keeled scales on its long tail, to which its common name refers.  It is one of the larger members of the genus Ctenosaura, capable of growing to 4.3 feet (1.3 m) in total length (including tail), with females being slightly smaller than males at 3.3 feet (1.0 m).  It usually has a brown or grey-brown colored back (dorsally), with a yellowish underbelly (ventral surface).  It has a crest of long spines which extend down the center of its back.  Mating generally occurs in spring with the male showing dominance and interest by head bobbing before chasing the female until he can catch her and subdue her.  Within eight to ten weeks, the female will dig a nest and lay clutches of up to 24 eggs which hatch in 90 days with the babies digging their way out of the sand.  Hatchlings are often bright green with no body pattern and juveniles are typically green with brown markings, although all-brown hatchlings have been recorded.

Some wonder how a 4-foot (1.2 m) black-and-yellow lizard went unnoticed on Clarion Island for decades.  Clarion’s landscape has changed dramatically in recent years. The island was covered in prickly pear cactus (genus, Opuntiathat) that made exploration difficult, but was consumed by sheep (Ovis aries) and pigs (Sus domesticus) introduced by thew Mexican Navy in the 1970’s.  Those animals are gone and a shrubland community (chaparral) remains.  The iguanas are wary of humans and hide when approached.  The destruction by sheep and pigs underscores the damage invasive animals can cause.  Island ecosystems are particularly vulnerable.  Rayna Bell, an evolutionary biologist at the California Academy of Sciences said, “This type of work is fundamental to conserving some of the world’s most unique and imperiled diversity.”  Mulcahy’s colleagues are working to spread the news to government officials in Mexico to stop the eradication program.

THOUGHTS: The spiny-tail iguana is a traditional food in Mexico, listed as “Least Concern” by the IUCN Redlist, but the species is listed on the Mexican Red List as threatened and it is illegal to hunt them.  Their presence on Clarion suggests a 700-mile trip on a floating mat of vegetation.  It would be the second-longest known iguana aquatic journey, topped by another species of iguanas traveling 5,000 miles from North America to Fiji.  Humans thought the 1947 Kon-Tiki expedition was amazing.  We are always outdone by nature.  Act for all.  Change is coming and it starts with you.

Screwworm

November 10, 2025

The Sunday before Halloween, the Homes section of my local newspaper ran a Reutters article detailing a new sterile fly plant added in Mexico.  In Metapa, Mexico, engineers, veterinarians, and entomologists are racing to repurpose a plant that will play a pivotal role in trying to eradicate the flesh-eating fly threatening the country’s cattle industry and raising tensions with the US.  The facility used to help control Mediterranean fruit flies, but workers are dismantling old infrastructure and rebuilding specialized laboratories designed to mimic the conditions of an animal wound.  The plant aims to be ready by July 2026 and would double the number of sterile flies Mexico can release into the wild.  The US has kept its border mostly closed to Mexican cattle imports since May 2025 and has invested US$21 million towards the US$51 million facility in Chiapas state in an effort to keep the screwworm fly out of America.

When I went online, I found the New World screwworm fly (Cochliomyia hominivorax), or simply screwworm, is a species of parasitic blowfly which is present in the New-World tropics.  The screwworm larvae (maggots) eat the living tissue of warm-blooded animals.  Of the four species of Cochliomyia, only the species hominivorax is parasitic, but a single parasitic species of Old-World screwworm fly is placed in a different genus (Chrysomya bezziana).  The maggots of many fly species eat dead flesh and may occasionally infest an old and putrid wound.  Infestation of a live vertebrate animal by the screwworm maggot (myiasis) is unusual because they attack healthy tissue, increasing the chances of infection, which then attracts more flies.  Screwworm females lay 250 to 500 eggs in the exposed flesh which hatch and burrow into the surrounding tissue as they feed.  If the wound is disturbed during this time, the larvae burrow or “screw” deeper into the flesh, giving the larva its common name.  The maggots can cause severe tissue damage or even death to the host.  About three to seven days after hatching, the larvae fall to the ground to pupate, reaching the adult stage about seven days later.  The female will mate four to five days after hatching and can lay up to 3,000 eggs and fly up to 120 miles (200 km) during her life.  Males mate up to ten times, but females mate only once and retain the male’s sperm for life, leading to the sterile eradication technique.

The screwworm was the first species to be tested with the sterile insect technique and resulted in control and systematic eradication of the species from the US, Central America, and parts of the Caribbean beginning in the 1950’s.  The US and Mexico bred and released more than 94 billion sterile flies from 1962 to 1975.  By the early 2000’s, it was considered eradicated from North America, but was detected in Mexico in 2024 and 2025, prompting renewed efforts to prevent its re-emergence.  The fly is still widespread in tropical and subtropical parts of the Caribbean and South America and animals imported from these areas must be inspected or treated to prevent the pest’s reintroduction.  Eradication efforts continued and in 1998 the first sterile flies were released in Panama with the goal of creating a barrier zone at the Darién Gap against a screwworm invasion.  This is achieved through weekly sterile screwworm releases of up to 50 million insects bred in factories and sterilized by ionizing radiation.  The bred insects must not suffer any impairment to compete with wild, fertile insects.  In September 2025, a case of New World screwworm was found in Sabinas Hidalgo, Mexico, less than 70 miles (110 km) from the US-Mexico border.

THOUGHTS: When sterile screwworm males’ mate with wild females no offspring are produced, and the population collapses over time.  Coordinator Jose Luis Quintero said, “The screwworm was eradicated once before in Mexico — it took 19 years.  We hope to do it in far less time.”  Let’s hope that is the case.  Act for all.  Change is coming and it starts with you.

Freeze

November 08, 2025

The front page of yesterday’s local newspaper ran a USA Today article telling gardeners how to prepare for the impending cold snap.  The first frost in Arkansas’ River Valley usually takes place around November 5.  Scot Covert, chief meteorologist at KFSM-TV, said we will be a little late this year, “we’re looking at Monday the 10th.”  Even before temperatures dip to 32 F (0C), frost can form in low lying areas like gardens (raised beds?) as plants cool faster than the surrounding air.  Randy Forst, extension educator with the University of Arkansas Division of Agriculture, said, “All indoor tropical plants and house plants should be moved into an area that does not go below 35 degrees.”   If you do not take this precaution, it is likely they will freeze.

When I went online, I found that a freeze will damage vegetables by causing ice crystals to form and expand inside the plant which ruptures the cell walls.  A freeze can cause visible damage like wilting, blackening, or water-soaked areas in the leaves.  While most vegetables are negatively affected by freezing (while in the ground), root vegetables and cabbages (brassicas) can become sweeter after a light frost as the cold converts their starches to sugars.  After they thaw, freeze-damaged vegetables are often softer and mushier than their fresh counterparts.  A hard freeze (28F/-2C for several hours) can kill plants outright.  That is particularly true for warm season crops like tomatoes (Solanum lycopersicum) and peppers (Capsicum annuum).  Freezing halts the growth of microorganisms but does not stop all enzymatic activity, which can lead to a loss of quality over time.  That is one reason to blanche your fresh vegetables before placing them in the freezer.

Forst went on the say cool-season vegetables that can tolerate a freeze should be covered to prevent leaf-tip burn.  A bigger concern during this time of year is drought.  Arkansas does not tend to get the moisture needed to keep outdoor plants hydrated.  You need to water outside plants if it does not rain at least once a week.  Outdoor perennials can also use extra care.  Once a frost happens you should clip back the dead foliage and then cover the crown with a biodegradable mulch.  Annuals that bloom during the cool season should continue to receive a water-soluble fertilizer once a month.  Four types of action should be taken to aid your garden and outdoor plants.   Once the temps fall below 40F (4.4C) houseplants should be moved inside.  On clear, calm nights vegetables should be covered if the temps will get into the mid-30’sF (1.6C), then be sure to uncover them when temps rise back into the 40’s+F (4.4+C).  Outdoor plants should be watered weekly if there is low rainfall.  Finally, mulch any perennials after the frost kills the top growth.  These actions will aid your plants’ regrowth the following spring.  I had better cover my plants tomorrow.

THOUGHTS: My vegetables are not the only thing I need to protect against a freeze.  We purchased a used C class RV and it is now approaching our first winter.  Everything I have read extolls the virtue of winterizing the unit if you are going to store it during the cold months.  Part of the process involves draining and pouring food grade antifreeze into the lines and tanks.  Once I do this, I cannot use the RV until I again drain and flush the lines.  While I should just bite the bullet and shut the unit down, I have wavered to the point where it is almost too late.  Our repair person told me the lines are enclosed within the vehicle so I should be fine turning on the water tank heaters and the furnace set low to keep everything warm.  The freeze is set to only last two nights and then it will warm up to the 70’sF again.  I hope I do not regret this decision.  We often delay action until it is too late.  We must address our environmental and communal issues/disagreements now rather than later.  Act for all.  Change is coming and it starts with you.

Erosion

November 07, 2025

I have been going to a coffee shop to visit a friend every month or so.  I always enter from the rear of the building into the semi-outdoor seating area.  This is enclosed with glass doors that can be raised when the weather is appropriate, although I have never seen them raised.  Several years ago, they did some remodeling on the exterior to replace the concrete that backed up to the mini-mall parking lot where it was located.  The shop has an AC unit on top of the building and a downspout that channels the water off the roof and out to the street.  Over the years this has resulted in the water cutting a path from the spout to the parking lot.  When I arrived this last week, it impressed me with the power of water to cause erosion.  

When I went online, I found water erosion is the process of soil and rock being moved by water.  This erosion can be categorized into types.  Splash erosion comes from the impact of raindrops detaching soil particles.  Sheet erosion is the removal of a thin, uniform layer of soil across a slope.  Rill erosion is the small, channel-like cuts formed by runoff water.  Gully erosion is the larger, more-defined channels that develop from rills.  Stream-bank erosion is the wearing away of the banks of a stream or river.  Coastal erosion is the wearing away of land along the coastline, often caused by wave action.  This natural process shapes landscapes by carving out valleys and canyons, but human activities like deforestation and farming can accelerate it, impacting soil quality and water resources.  Techniques to control water erosion include keeping soil covered with vegetation, practicing conservation tillage, and building structures like terraces and grassed waterways.  The erosion at the coffee shop appears to be rill erosion.  I suppose if left long enough it would become gully erosion.

While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which soil erosion is occurring globally.  At agriculture sites in the Appalachian Mountains, intensive farming practices have caused erosion up to 100 times the natural rate of erosion in the region.  Excessive (or accelerated) erosion causes both “onsite” and “offsite” problems.  Onsite impacts include decreases in agricultural productivity and even ecological collapse from the loss of the nutrient-rich upper soil layers and in extreme cases this can lead to desertification.  Offsite effects include sedimentation of waterways and an accumulation of nutrients (eutrophication) in a body of water.  Both can result in an increased growth of organisms that may deplete the oxygen in the water.  Intensive agriculture, deforestation, roads, anthropogenic climate change (global warming), and urban sprawl are among the most significant human activities regarding their effect on stimulating erosion.  There are also prevention and remediation practices that can curtail or limit erosion of vulnerable soils.

THOUGHTS: I recall being amazed when they had to shut down the 20-year-old spillway outlet at the reservoir where I fished in high school.  The outlet Shannel had two massive rows of 20-foot-high (6 m) concrete blocks that had suffered erosion from the water being released and were needing to be replaced.  Famous examples of water erosion include the Grand Canyon, formed by the Colorado River; the Mississippi River Delta, a large fan-shaped deposit of sediment; and Niagara Falls, which is slowly receding upstream due to erosion.  Water and wind erosion are the two primary causes of land degradation and are responsible for about 84% of degraded land globally, making excessive erosion one of the most significant environmental problems worldwide.  While erosion is a natural process, humans can choose to lessen (or increase) the effect by our actions.  It takes eons for the landscape to recover, if it does at all.  Act for all.  Change is coming and it starts with you.

Checkered

November 05, 2025

It is getting colder at night, and I am still waiting to see if my second crop vegetables will produce.  I have flowers (and even tiny fruit) on my peas (Pisum sativum).  The cabbage (Brassica oleracea) is growing well but has yet begun to make a head.  The same can be said for my broccoli (Brassica oleracea).  I have two small watermelons (Citrullus lanatus) but it is doubtful they will survive long enough to harvest.  I also have two leafy vegetables that are doing well.  The iceberg lettuce (Lactuca sativa) has yet to produce a head, and the spinach (Spinacia oleracea) is small but holding its own.  We are predicted to have the temperature drop to 28F (-2C) or colder for several hours (a hard freeze) this weekend.  A hard freeze effectively ends the growing season by killing any remaining annual plants and most seasonal vegetables.  When I went out to check my beds this morning, I found yet another new species of butterfly on the wildflowers, a common checkered-skipper.

When I went online, I found the common checkered skipper (Burnsius communis), formerly known as Pyrgus communis, is a species of butterfly in the family Hesperiidae.  It is known as the frequently seen spread-winged skippers (Pyrginae) species in the northern US by collectors and watchers alike.  The common checkered skipper has a wingspan of 0.75 to 1.25 inches (19 to 32 mm).  It gets its name from the checkerboard pattern on its wings.  The male tends to have broader bands than the female.  The body tends to be blue-gray with the small amount of “fuzz” which is seen in all skippers.  This butterfly can be found in gardens, parks, fields, roadsides, riverbanks, lowlands and foothills throughout southern Canada and almost the entire expanse of the US.  It has also been seen in Mexico.  In southern regions the checkered will fly all year with multiple broods.  In the north it will have two broods and fly late into the fall. 

Much like the variegated fritillary, the checkered skipper overwinters as a fully grown caterpillar (or a late-stage instar caterpillar) in a rolled-up leaf or other shelter it creates on its host plant.  This period of dormancy (overwintering) lasts from late fall until spring.  The caterpillar then forms a chrysalis (pupates) and emerges as an adult butterfly.  I did not see any monarchs (Danaus plexippus) so hopefully they continued their journey South.  The cold predicted for this weekend means the adult butterflies still present are on short time.  The checkered cannot survive very cold winters and may not be a permanent resident north of the 40th parallel.

THOUGHTS: The 40th parallel north is not just significant as a division line for the checkered skipper, it also holds significance as a historical and geographical landmark in the US.  This was the boundary between the Kansas and Nebraska territories established by the Kansas-Nebraska Act of 1854.  The Mason-Dixon Line is generally thought of as the dividing line between the Northern and Southern states during the US Civil War, but the original line established the border between Maryland and Pennsylvania colonies.  The colonies both claimed the area between the 39th and 40th parallel.  The Mason-Dixon line settled the boundary question at a northern latitude of 39 degrees and 43 minutes.  The line was marked using stones, with Pennsylvania’s crest on one side and Maryland’s on the other.  It is ironic how arbitrary lines of division separate humans into categories of “us” and “them”.  We need to look beyond these divisions and find the sameness of all.  Act for all.  Change is coming and it starts with you.

November 05, 2025

As Fall stretched into late October, I was amazed by the dozens of pollinators which still flocked to the wildflower bed in front of our house.  My guess is they are still stocking up for a flight south or survival during the long winter.  We have several coneflowers (family, Asteraceae) along with a proliferation of orange sulfur cosmos (Cosmos sulphureus).  Yesterday afternoon was bright, sunny, and in the mid-70 F’s (24 C’s) and they were still out in full force.  There were several late traveling monarch butterflies (Danaus plexippus) along with dozens of bumblebees (Genus, Bombus) flitting from flower to flower.  There was also a new arrival (at least I had not noticed) with several smaller brightly colored butterflies.  Two characteristics struck me about these Lepidoptera.  First was the speed they were traveling as they drew nectar from around the bed, the second was variegated wings.

When I went online, I found the variegated fritillary (Euptoieta claudia) is a North and South American butterfly in the family Nymphalidae.  The variegated flight is low and swift and even when collecting nectar, the species is extremely difficult to approach.  This has earned the genus name which taken from the Greek “euptoietos” meaning “easily scared”.  The wingspan of the adult variegated measures 1.75 to 2.25 inches (44 to 57 mm).  The upper side of the wings is checkered with orange and black, and both the fore and hind wings have a row of submarginal black spots and black median lines running across them.  The underside of the forewing is orange with a pale orange spot rimmed in black in the forewing cell.  The underside of the hindwing is mottled with browns and grays with a pale postmedian band.  The variegated fritillary has three very different characteristics that distinguish them from the genus of greater fritillaries (Speyeria fritillaries), but it is still closely related to them.  Variegated fritillaries have two or three broods per year (Speyeria one), are nomadic (Speyeria sedentary), and use a wide variety of host plants (Speyeria only violets). 

While the variegated fritillary is nomadic, it is not (officially) migratory like the monarch.  Instead, it overwinters in its caterpillar stage in the leaf litter, seeking shelter and entering a dormant state (diapause).  In warmer climates, adult butterflies may also overwinter.  In Arkansas the adults need to either migrate south or they will die (freeze).  Caterpillars can survive Arkansas’ winter temperatures and will emerge from their hibernation to form cocoons (pupate) in the spring.  The survival of the caterpillars (or adults farther South) depends on factors like predation, temperature, and the amount of insulation provided by leaf litter.  When weather conditions improve in the Spring the caterpillars emerge from their winter hibernation to continue their life cycle.  While I was planning on clearing the bed and scattering the seed, perhaps I should wait until new life emerges in Spring.

THOUGHTS: I can attest to the “euptoietos” nature of the variegated fritillary.  It took me 10 minutes for one to wait long enough on a flower to get a picture.  The butterflies would fly up to 30 feet (10 m) away and then dart back to seek out another flower or two before repeating the maneuver.  I find it interesting how different species have adapted to survival during the cold months of winter.  This also explains how a warm day can bring out a swam of flying insects as they emerge from their sheltered refuge.  Humans do not naturally go dormant (hibernate) because our bodies lack the necessary biological adaptations to enter a state of deep sleep with a significantly lower body temperature and metabolic rate.  The earliest evidence of controlled use of fire dates back at least 1.8 million years ago, but evidence for habitual or widespread use of fire does not become clear until around 400,000 years ago.  We rely on protective structure, clothes, or sources of heat to achieve what nature has given other species.  Act for all.  Change is coming and it starts with you.
