A new species of Brook newt has been described from the Montseny mountians near Barcelona, Spain. And together with this description Euproctus asper has changed name to Calotriton asper.
Anyone who wants a pdf of this paper (1 MB) can send me a private message, I'll sum them up and send it next week in one time.

European species are in as much turmoil as the asians! With all this changing, I can't keep everything straight.

I would also like a copy of the paper too, Serge. Thank you!
 
As I wrote very clearly: send me a private message, than I'll send you one. Then I can do it in one time somewhere next week, saves me sending 1 MB every time ;-)

A team of scientists has just discovered a new species of mountain triton in the Montseny Nature Reserve. The species has been given the scientific name Calotriton arnoldi. It is the only endemic vertebrate species currently known to exist in Catalonia and a report of the discovery has been published in the December edition of the prestigious Zoological Journal of the Linnean Society. The authors are Salvador Carranza, ?Ramon y Cajal? researcher from the Department of Animal Biology at the University of Barcelona, and F?lix Amat, who works with the Herpetology Department of the Science Museum in Granollers (Catalonia). The research which led to the discovery began over three years ago and forms part of the plan designed to monitor ecological parameters in the above-mentioned nature reserve.

The Montseny triton presents a set of genetic, morphological and osteological features that make it unique and distinguish it from its closest relative, the Pyrenean triton. C. arnoldi, named in recognition of the British herpetologist E. N. Arnold of the Natural History Museum in London, has smoother, brownish skin, which is translucent in the ventral area, and both sexes are smaller. It also shows differences in the morphology of the vertebra at the base of the tail. Mitochondrial DNA analyses reveal that the Montseny triton separated from the Pyrenean triton around 1.5 million years ago, during the first Pleistocene glaciations.

Despite their age, however, the first Montseny tritons were not observed until 1979, probably due to their scarcity, their discreet behaviour, and the fact that they were only to be found in a small number of cold water streams in the Montseny. To be precise, the new species C. arnoldi has been located in five streams of the Montseny massif (between 600 and 1200 m), and appears to prefer the beech forest (Fagus sylvatica). Preliminary studies indicate that it could be the amphibian with the smallest distribution area in Europe, and is one of the most endangered.

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!
