Did you know Achoque salamanders have 'superpowers'?

Laboratorio de Biología Acuática (who we support) have made a beautiful video about these astonishing but Critically Endangered amphibians.

Click to watch! The art starts at 35s in. 🌎🦎

Working hard on International Day of Women and Girls in Science. Lucky to have the opportunity to study lots of animal species, their DNA, and even their bacteria! #11F 🧬🦎🐜🦠🧪👩🏽‍🔬

We´re seeing a similar paradox in Mexico. Green iguanas are native and protected by the environmental law, but there are new populations outside their original range (e.g. Baja California Peninsula). Besides the ecological issues, this confuses the general public. 🦎🌎

I really enjoyed Costa’s book and learning how Wallace had an impact on many scientific fields. Happy birthday Wallace!

I was happy to see my two favourite volcanoes again: Popocatepetl (left, active, 5,393 m, Smoking Mountain in Nahuatl) and Iztaccíhuatl (right, dormant, 5,230 m, White Woman in Nahuatl). However it’s worrying that the glaciers are quickly disappearing 🗻🇲🇽 #climatechange

Merry Christmas from Axolotl lake, Xochimilco 🇲🇽. Sadly very few axolotls are left in the wild. We visited an “ajolotario” and saw these two cute guys. 🌎🐸

Went for a run early enough to catch the Tacaná volcano silhouette against the sunrise colours. It is an active volcano but it has been calm for almost 40 years, I hope it continues like that 🌋🇲🇽

Worried about the people in Jamaica. I'm also worried about the only surviving wild population of the critically endangered Jamaica rock iguanas (Cyclura collei), I hope they find a place to hide. 🦎🌎🧪

Achoque Salamanders: Microchipping One Of The World’s Rarest Amphibians
Achoque Salamanders: Microchipping One Of The World’s Rarest Amphibians YouTube video by IFLScience

Fewer than 150 achoque may survive in the wild, and we need a way to monitor their health and other factors to better protect them.

Good news, though: our scientists have carried out the first ever successful microchipping trial on these salamanders!

I was happy to contribute to this interesting genomic and biochemical study on the powers of Glutamicibacter spp! This strain, isolated from a pristine cenote in Yucatán, is halotolerant and can potentially be used in bioremediation. www.sciencedirect.com/science/arti... 🧪🦠🧬

My favourite reptiles: They live in amazing places e.g. Baja California and the Galapagos islands, they’re seed dispersers, some are fragile other very resilient, culturally important but threatened by habitat loss, trafficking, hunting. Today is Iguana awareness day! Photo:IIF 🌎🦎

Sharing a video of Catemaco 🇲🇽 for #WorldLakeDay, surrounded by the volcanic Sierra de Los Tuxtlas and some patches of the original rainforest. It’s one of the sampling sites in our eDNA project.
