a weekend of Dutch secrets

Postby Jeroen Speybroeck » Thu May 28, 2015 9:31 am

The Netherlands. Not exactly the richest country in Europe herpwise. "Fortunately", some people introduced a bunch of stuff.

Here's what we found.

Triturus cristatus
Triturus marmoratus *
Ichthyosaura alpestris *
Lissotriton vulgaris
Pelobates fuscus
Bufo bufo
Hyla arborea *
Rana temporaria
Rana arvalis
Pelophylax ridibundus
Pelophylax lessonae
Pelophylax kl. esculentus
Podarcis muralis *
Zootoca vivipara
Anguis fragilis
Elaphe schrenckii *
Natrix natrix *+
Vipera berus
(*: non-native population, *+: native and non-native)

With some more "luck", we could have even added non-native Bombina variegata, Alytes obstetricans and Rana dalmatina.

new evidence supports the hypothesis that the sirtaki was in fact invented by Dutch herpers looking for Rana arvalis

I invite my companions to add more.

A question for all - ever seen such a checkered marmoratus belly?

nice pictures :)

Hyla arborea is not native to the Netherlands?
Triturus marmoratus: I now specimens/populations with uniform black bellies (Miranda, Bejar, Spain) and with creme coloured bellies (S France). But never seen such marbled ones.

Sure it is. Muralis and alpestris too. Just not to the area where we were.

Marbled Newt (Triturus marmoratus) - these are the same individuals Jeroen already showed, but they are too beautiful not to look at them again! And again...
