Eastern Massasauga Rattle Snakes are Resorting to Incest and Humans May Be to Blame

Michigan bell snakes have been separated into small isolated populations thanks to human roads, farms and buildings. And this is a serious problem, according to a new study in the Proceedings of the National Academy of Sciences,, This shows that these already threatened snakes are forced to mate with members of their own populations, undergoing their ability to survive and reproduce.

“Even a single road can isolate populations,” said biologist Sarah Fitzpatrick, study author and associate professor at Michigan State University, according to a press release. “They are very vulnerable to even minor disturbances to their habitat.”

Massasauga Oriental

The Massasauga Rattlega mast (Catenatus sistrurus) is the only poisonous snake seen in Michigan, and one of the only poisonous snakes that slips into the Midwest of the United States.

Although it can have a bad rap – the bites are relatively rare but dangerous, sometimes fatal – this thick and greyish -brown meal snake is always important for the health of the humid areas of the midwest, the consumption of rodents such as mice and rats and prevent their populations from reaching barns and human houses.

According to the US Fish and Wildlife Service, however, the loss and fragmentation of the habitat have left this species poorly understood threatened wherever it is found, humans limiting the mobility of oriental massasaugas in their traditional range.

This means that these snakes are more likely to reproduce with members of their same population – including their relatives – which leads to offspring which is less capable of surviving and less able to produce offspring themselves.

Cracking of cracking snake

To find out more about this phenomenon, researchers have studied more than 1,000 snakes in Michigan during 15 years. They found that the most consanguineous people were 11.6% less likely to survive from year to year and 13.5% less likely to produce surviving offspring.

According to the study authors, research shows that the restoration of the habitat of the bell serpent is necessary, not only in Michigan, but also in other Midwest states.

“These are fairly large and stable populations of oriental Massasaugas,” said Fitzpatrick in the press release. “The fact that we detect the problems of consanguinity in these populations is worrying, since many other Midwest populations are much smaller and even more fragmented.”

Capture and take the naked snakes

To achieve their results, researchers funded by fish services and fauna crossed Michigan’s wet areas with rubber boots and snake pliers. Whenever they stumbled on an oriental massasauga, they picked it up, measured it and sample his blood, which they then analyzed to sequence his genome. This allowed the team to recreate the ancestry of a snake and to compare the ancestry of two collected people.

The team has implemented tiny micropuits called passive transponders or intaglies integrated into each eastern Massasauga to facilitate the identification of snakes after their release. During 15 years, the researchers saw the wetlands, capturing and taking up the same snakes to follow their survival.

“This long -term surveillance in the field is the backbone of the study,” said biologist Meaghan Clark, another study author and a former doctorate. A student at Michigan State University, according to the press release. “Getting people out every season to catch these snakes has made it all possible.”

The results have revealed that conservation efforts are necessary to help Eastern Massasaugas survive and reproduce in Michigan and elsewhere. Among the possibilities of these conservation efforts are home restoration projects – including the construction of wild passages – and projects to relocate snakes, which would promote the connectivity of the habitat and prevent population reductions due to consanguinity.

The result could be stronger and healthier wetlands through the Midwest, all thanks to these threatened and misunderstood snakes.
