Hi all,
As an project for my study; applied biology, I am doing an Herpetofauna survey of an area located in the southern part of the western Rhodopes (Bulgaria). Now in my second month here, I've found quite some species already. Frogs are not yet my field of expertise. But also found some frog species, among them a type of frog which, from my point of view, could be one of three species, namely: Rana temporaria, Rana dalmatina or Rana graeca, all present in the western Rhodopes as a whole. Following this link:

you will see the photos on my flickr account. The first 3 photos are taken on an altitude of 1155 m, in a high meadow area, the rest were taking on an altitude between 925 and 930 m, along a river in a valley.
Are they all the same species or more than one? And which species would it be in your opinion?
Hope you guys could help me with this, thanks in advance!
Greetings Tycho
