Congratulations to Biologic’s zoologist Tom Rasmussen, who is the co-author of a recently published paper “ A large-scale automated radio telemetry network for monitoring movements of terrestrial wildlife in Australia”.

The paper discusses a rapidly expanding cooperative automated radio-tracking global network (Motus) which Tom helped to introduce to Australia and which Biologic have used to monitor movements of multiple threatened species in WA.

More new Gehyra species!

More new Gehyra species, six to be exact, were just described in a recent paper co-authored by one of Biologic’s Senior Zoologists, Ryan Ellis.

The paper (available open access HERE) resolves the taxonomy of the Gehyra australis and Gehyra koira species complexes, which occur across the monsoon tropics of northern Australia.

The paper provides a redescription of two species (G. australis and G. koira), redescription of G. ipsa as a full species (formerly G. koira ipsa), description of three new species within the G. australis complex (G. arnhemica, G. gemina, and G. lauta) and three within the G. koira complex (G. calcitectus, G. chimera and G. lapistola).

The new species are a great example of cryptic species (i.e. species that are genetically distinct yet still look very similar) and that species can evolve to be genetically distinct without the way they look differing great deal (why change if you don’t need to?). For example, one of the new species (G. chimera) is genetically more closely related to G. koira but looks more similar to species in the G. australis complex.

The Biologic team is looking forward to getting up into the Kimberley and getting some of these new species in hand in the near future.

The Mornington Blindsnake, Anilios vagurimus

Biologic would like to introduce the newest Australian snake species to be described, Anilios vagurimus or the Mornington Blindsnake. The species was described by Biologic Senior Zoologist Ryan Ellis in a paper published on New Year’s Eve in the journal Records of the Western Australian Museum (available open access HERE), what a way to end the year!

The Mornington Blindsnake is a morphologically distinct (for a blindsnake anyway) species known from a single specimen in the central Kimberley, with no known photos of the species in life. The description of A. vagurimus increases the number of species in the genus to 48, the most diverse genus of snakes in Australia and one of the top ten most diverse snake genera globally.

What’s in a name: The name vagurima is formed from the Latin words vagus (wandering) and rima (cleft), meaning wandering-cleft, in reference to the diagnostic path of the nasal cleft (a small suture in the nasal scale) possessed by the species which can be used to identify it from other species.
