- With fewer than 100 individuals believed to exist in the wild, the Lake Pátzcuaro Salamander (Ambystoma dumerilii) or achoque, found only in and around Lake Pátzcuaro in Michoacán, Mexico, is critically endangered. They’re getting help from an unusual corner: Dominican nuns at a nearby convent, who for the past 150 years have been raising the salamanders in captivity. (They use them to make a “mysterious” medicine: a cough syrup called jarabe.) See this long and fascinating read in the New York Times, which is accompanied by first-rate photography.
- A biologist is warning that Okanagan populations of the Northern Pacific Rattlesnake (Crotalus oreganus) are 100 years from extinction. The snake is at the northern limits of its range, and it’s down to between 1,500 and 2,500 individuals. It’s listed as a threatened species. There are populations in more trouble, and sooner (see above), but this is worth keeping an eye on.
- Male rattlesnakes engage in ritual combat during mating season. Here’s video of a pair of male Timber Rattlesnakes (Crotalus horridus) getting fighty with each other. Here’s another video from California, species unidentified.
- A beautiful essay by Laura Marjorie Miller on the controversial plan to reintroduce the Timber Rattlesnake to an island in the Quabbin Reservoir in Massachusetts, which I’ve mentioned in previous roundups.
- Where do snake-handling cults get their snakes? As The State discovered, South Carolina. Thanks to the lack of restrictions on the sale of venomous snakes, snake-handling preachers from other states regularly buy their snakes at reptile shows.
- CityLab takes a look at Isha Serpent, a volunteer snake rescue group in Madhurai, India; the snakes being rescued include spectacled cobras, kraits, and Russell’s and saw-scaled vipers. The group’s been active since 2009 and has relocated more than 2,000 snakes—with, they claim, no envenomations.
- A new study suggests that cats have a significant impact on reptile populations: in a field experiment, cats were removed from six 64-hectare plots; over a two-year period, reptile populations rebounded significantly in those areas. [Biological Conservation]
- A fossil snake embryo or neonate from the late Cretaceous has been found preserved in amber in Myanmar. [Science Advances]
- One of the most common questions people like me get from strangers: how do I snake-proof my yard? Here’s a comprehensive answer: I think I’ll point people to it from now on.
- Last month the Herpetologists’ League gave Richard Vogt the Distinguished Herpetologist award. Vogt, who made the significant discovery that incubation temperature can determine a turtle’s sex, proceeded to pepper his plenary lecture with photos, some of which were “censored” with coloured boxes, of his scantily clad students. (Research on aquatic reptiles often involves swimwear, but Vogt was apparently, and regularly, gratuitous.) Stories soon followed about Vogt, who appears to be someone female herpetologists have to warn one another about. News coverage in the #metoo era—local from the Rochester Democrat & Chronicle, national from the New York Times—was inevitable. Vogt’s award was rescinded, the League’s president has resigned, there was much huffing and puffing from one former league president on Vogt’s behalf (and presumably others), and the League’s new president is taking a tough line on harassment and misconduct. A code of conduct is in the works.
Question I’ve answered on Quora recently:
- When feeding corn snakes, do you feed them in their enclosure or a separate feeding container?
- What terrarium should I get for my corn snake?
