Folge 32 (mit Frederic Griesbaum, Museum für Naturkunde Berlin) Natur 2.0 - Der Biodiversitäts-Podcast · Episode

In der neuen Folge Natur 2.0 durfte ich mit @thoerren.bsky.social über heimische Amphibien&Reptilien und ihre Gefährdung sprechen.
Außerdem ging es darum, wie jede*r mithilfe von #CitizenScience Plattformen zur Biodiversitätsforschung beitragen kann!

Happy #WorldFrogDay!!!

My first #amphibians of the year!
Rana temporaria and Lissotriton vulgaris from Berlin, Germany.

Please share this post among your fellow frog and field-herpetology people! ✌🏼🐸

Hey #frog people!
If you are using @inaturalist.bsky.social, please feel invited to the new „Frogs in Amplexus“ project!
We try to collect all amplexi, (to be) recorded on iNat. So please consider to add your future amplexus observations, or such that you help identifying/correcting. #amphibians

New paper in @nature.com led by @patricepottier.bsky.social! We demonstrated global vulnerability of amphibians to warming, threatening 10% of >5,000 species examined. How did we do it? See thread🧵

To kick-off my Bluesky, I want to highlight a paper from earlier this year - the first one together with my best friend @stacheljochen.bsky.social 👬🏼
We report several #Natrixnatrix from #Berlin with untypical pattern.
Hopefully, we can find out what’s happening there genetically, next year.
