This #OpenAccess research provides the first genetic evidence that native grass snake populations in Berlin have been compromised by the introduction of at least one foreign subspecies, originating from the southern Balkans and western Asia Minor. bit.ly/3S0bojh @fg-wild.bsky.social 🌍 #EvosSky

🐢Based on 1,770 records of non-native #terrapins in Germany, drawn from published sources and publicly available #citizenscience #data, researchers have confirmed the presence of 14 wild non-native terrapin species in Germany. ➡️Find out which ones in our #OA journal: doi.org/10.3897/neob...

9 different panels in alphabetical order, showing the distribution map of nine non-native terrapin species in Germany, sorted by taxonomy. Full circles represent precise locations, empty circles are obscured observations. Species are (no. of records in brackets). A. Graptemys ouachitensis (n = 19); B. Graptemys pseudogeographica (n = 106); C. Pseudemys concinna (n = 166); D. Pseudemys nelsoni (n = 31); E. Pseudemys peninsularis (n = 4); F. Trachemys scripta (n = 1237); G. Chrysemys dorsalis (n = 2); H. Chrysemys picta (n = 31); I. Emys orbicularis (n = 150). The map displays the federal states as well as major rivers for orientation purposes (from Natural Earth). Sources of terrapin photos are given in the Suppl. material 1.

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

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.
