“Round and round they went with their snakes, snakily”*…

 

Python

 

If pythons are the snake that ate the Everglades, the apocryphal legend of their takeover begins with an appropriately cinematic opening scene. In 1992, Hurricane Andrew plowed into the state, killing 65 people and leveling thousands of homes, as well as—so the story goes—a Burmese python breeding facility.

The reality of their introduction to the area may be less exciting. “The scientific thinking, I believe, is that they were probably animals that were discarded by pet owners deep down into the Everglades,” said Steve Johnson, an associate professor of wildlife ecology and conservation at the University of Florida.

The population of Burmese pythons in the Everglades is impossible to measure with much accuracy. Since the first reported sighting of one in the wild in Florida in 1979, their numbers have exploded. Estimates from the USGS indicate there could be tens of thousands to hundreds of thousands of them in South Florida. Regardless of their actual population size, their impact is clear: pythons have decimated biodiversity in the area. The hungry snakes will consume almost any animal in their path. They seize their prey using sharp, rear-facing fangs that are long enough to pierce a hunter’s arm. Then the snake coils around its victim, constricting the animal until it’s dead. Some hunters, to protect their lower legs from bites, wear camouflage-patterned snake gaiters, light armor that’s similar to shin guards worn by soccer players. But most go without, preferring intuition and quick reflexes over adding another layer of clothing to sweat through in the muggy glades.

To stem the tide of invasive species from the exotic-pet trade, the FWC holds amnesty days that allow pet owners to surrender animals to the agency without penalty. Although most pets that get released into the glades don’t survive, some outlier species like the Burmese python become established in their new ecosystems.

In this case, “established” sounds like an understatement. Pythons have taken over. Everything else has become prey. Since 2003, rabbit populations have disappeared from USGS study areas. Foxes, raccoons, possums, bobcats, and other species are all but gone. Pythons devoured the mammals and have moved on to birds, other reptiles, and possibly fish. The snakes can bring down animals as large as deer—which can either struggle and tear themselves away or become dinner—and even alligators.

Scientists have long suspected that pythons were consuming whole populations of small mammals in the Everglades and have made efforts at estimating the impacts. But exact population counts are impossible in such a vast wilderness. In a 2015 study led by Robert McCleery at the University of Florida, researchers translocated marsh rabbits into an area of the Everglades inhabited by a large number of pythons. At first the rabbits survived. Then temperatures began to rise, and with the warming weather, pythons slithered out of hiding and began to feast. In one year, they had eaten 77 percent of the rabbits…

Pythons are devouring native animal life in the unique ecosystem of South Florida. To help solve the problem, Florida Fish and Wildlife officials have turned to amateur and professional hunters to round up the reptiles in a wild competition called the Python Bowl: “The Misunderstood Python Hunters Saving the Everglades.”

As we ruminate on reptiles, we might recall that it was on this date in 1780 that a combination of thick smoke, fog, and heavy cloud cover caused so complete a darkness to fall on Eastern Canada and the New England area of the United States that candles were needed at noon.  The drear, known as “New England’s Dark Day,” did not disburse until the following evening.

“Behold, I give unto you power to tread on serpents”*…

During St. Patrick’s Day, most revelers won’t remember the patron saint of Ireland for his role as a snake killer. But legend holds that the Christian missionary rid the slithering reptiles from Ireland‘s shores as he converted its peoples from paganism during the fifth century A.D.

St. Patrick supposedly chased the snakes into the sea after they began attacking him during a 40-day fast he undertook on top of a hill. An unlikely tale, perhaps—yet Ireland is unusual for its absence of native snakes. It’s one of only a handful of places worldwide—including New Zealand, Iceland, Greenland, and Antarctica—where Indiana Jones and other snake-averse humans can visit without fear.

But St. Patrick had nothing to do with Ireland’s snake-free status, scientists say….

As we just say no to serpents, we might send chronically-correct birthday greetings to Georges-Louis Leclerc, Comte de Buffon; he was born on this date in 1707.  A naturalist, mathematician, cosmologist, and encyclopédiste, Buffon formulated a crude theory of evolution, and was the first to suggest that the earth might be older than suggested by the Bible: in 1778 he proposed that the Earth was hot at its creation and, judging from the rate of its cooling, calculated its age to be 75,000 years, with life emerging some 40,000 years ago.

In 1739 Buffon was appointed keeper of the Jardin du Roi, a post he occupied until his death. There he worked on the comprehensive work on natural history for which he is remembered, Histoire naturelle, générale et particulière. He began in 1749, and it dominated the rest of his life.  It would eventually run to 44 volumes, covering quadrupeds, birds, reptiles and minerals.  As Max Ernst remarked, “truly, Buffon was the father of all thought in natural history in the second half of the 18th century.”
