A Water Snake Stirs up a Commune (Nam Nguyen) – via Herp Digest

VIETNAM NET (Hanoi) 5/12/21 A water snake has been considered as a ‘preternatural snake’ by residents of Tung Loc commune in the central city of Ha Tinh.

Over the past month, people in Tung Loc commune have kept discussing the appearance of a snake that laid eggs near a local family. A series of mysterious stories about this snake has been widespread dispersed in the commune. Locals proclaim this water snake as a preternatural animal and a living treasure of Tan Quang hamlet, where the snake appeared. They even built a temple for worship the snake.

If one visits Tan Quang hamlet and asks anyone about the snake, he will be told the same story about the appearance of the Mr. “mysterious snake,” as follow: In the morning of April 14, Ms. Nguyen Thi Ly in Tan Quang saw a yellow toad sitting near the wheel of her motorbike, in her home. Near the toad were small, white eggs.

Ly thought that these were toad eggs so she put them into a plastic bag and place the bag on her front yard. Several hours later, she was frightened seeing a water snake tied round the motorbike neck and it held the egg bundle by his tail.

The woman saw a magician named Son in her village, who told Ly to buy offerings and burn incense to ‘invite’ the snake to leave her home. After holding the rite, Ly put eggs into a bag of banana leaves and used a long stick to take the snake to the village’s power station on April 16, where an altar was made for the snake. However, some villagers did not believe that it was a mysterious snake so they released the snake to the field.

On April 20, magician Son confirmed that the “miraculous snake” would return to the village at noon of April 21. Some people were doubtful but they still went to the power station to wait for the snake. Until early afternoon, a local woman named Chinh saw a toad jumped from the power station and it was followed by the “miraculous snake.” Locals praised magician Son.

Since then, a lot of stories about the “miraculous snake” have been widespread. A temporary temple was built at the power station to worship the snake. Many people burned incenses, gave offerings to the snake. Hundreds of people from surrounding areas also flock to the village each day to worship the snake.

The village set up a “provisional management board” to manage the snake temple. Visitors have donated several thousands of USD to the temple, which is used to build a new temple for the snake.

The “miraculous snake” is around 70cm long, in light blue. It looks like a water snake in Vietnam’s delta. The snake lives by water, fresh orange juice and cereal powder.

The local government has been urged to crush out superstitious activities related to a water snake.

Tracking Lake Erie Water Snake in Fight Against Invasive Fish – via Herp Digest

ScienceDaily (Mar. 19, 2012) — UC's Lauren Flick, a 19-year-old, triple-major senior, will present findings at an upcoming regional conference on the first-ever use of a surgically implanted device to record the habits of snakes in their natural environment. This particular study holds promise in "keeping score" as Ohio's Lake Erie water snake defends its native habitat against an invasive fish species.

Thanks to research by a University of Cincinnati undergraduate student and two team members, there's a new tool that's now been tested and found to work in continuously recording the habits of snakes.

This small-scale study is the first-ever use of Lotek Archival Tags (LATs) on snakes, since the LAT devices were originally developed for use in avian and fish species due to LATs' ability to measure temperature and pressure -- measuring pressure translates into altitude and depth.

UC's Lauren Flick, a triple-major pursuing simultaneous undergraduate degrees in biology, psychology and criminal justice, will present the findings of the snapshot study, "Comparing the Effectiveness of Lotek Archival Tags (LATs) in a Behavioral Study of the Lake Erie Water Snake," at the March 23-25 Midwest Ecology and Evolution Conference, a conference specifically for undergraduate and graduate student research that will draw representatives from regional schools.

Participating in the study with Flick were lead researcher Kristen Stanford, a doctoral student at Northern Illinois University and recovery plan coordinator for the Lake Erie water snake, and Lindsey Korfel, a student at Wittenberg University. Their research study was conducted during summer 2011 at Ohio State University's Stone Laboratory located on Lake Erie.

The traditional manner for tracking snakes' movements is primarily with a radio transmitter. In other words, a researcher would attach a location transmitter to a ground snake and then hope he or she could then stay or get within range over a period of time to visually determine its habits.

What Flick, Stanford and Korfel did was to catch two female Lake Erie water snakes (LEWS) and arrange for the implantation of LATs. Importantly, the LATs record and store data on the snakes over time, such that it's not necessary for a researcher to be within visual range of the snake. In fact, a researcher could leave the snake undisturbed in its natural habits and environment for days, even weeks, at a time when using a LAT. (During this study, the snakes were not harmed, and the LATs were removed at the end of the study.)

"This was proof of concept that use of LATs in reptiles is a viable research method," said Flick, a resident of Cincinnati's Green Hills community. "For a study like ours, it's harder and less effective to rely solely on using the traditional radio transmitter on a water snake moving in the depths of the Great Lakes. And even when using the average transmitter with a ground snake, you have to stay within about 50 meters for the tracking technology to work. That kind of close tracking could also serve to disturb the very habits a researcher is hoping to observe."

The Lake Erie Water Snake (LEWS), found only in the western Lake Erie waters of Ohio and Canada and only recently removed from the list of federally endangered and threatened species, is estimated to number more than 8,000 adults. Its population size had fallen to about 1,500 adults in the mid-1990s -- very low because they were often killed by humans and because of loss or degradation of habitat on the shoreline or on the Lake Erie islands where they are native.

Explained Flick, "Basically, the islands and shorelines are an important part of the snakes' habitat. They live on land and only forage in the water. Humans on the Lake Erie islands didn't, for a long time, see value in having snakes around, even though we now know that these nonpoisonous snakes were and are a valuable part of the ecosystem."

And while those numbers have recovered sufficiently to remove the species from the endangered status, it's important to understand how the species is faring in terms of foraging, maintaining body temperature and finding appropriate mating, resting and hibernating environments because the LEWS are a major player in combating the invasive round gobi fish.

The round gobies, a bottom-dwelling species, are considered very harmful because they are voracious nest predators of many of Lake Erie's native game fish and bottom-dwelling fish, and there are now estimated to be billions of the round gobies in Lake Erie. However, as it turns out, the native Lake Erie water snakes will eat round gobies.

And even though the student research was a snapshot involving just a pair of snakes, they found some intriguing results recorded by the LAT devices.

Said Flick, "Previous studies have estimated that the LEWS spend only 7 percent of the time foraging for food. The snakes that we studied actually spent 20-25 percent of the time foraging. One of the snakes even went out foraging at about midnight, which is unusual because the LEWS are not normally nocturnal."

And since it's estimated that 90 percent of the LEWS' diet consists of round gobi fish, more time eating by the LEWS should translate into fewer round gobies.
