Glad you liked the book. :roll:

You are making a habit of "asking before reading", I see? On p. 10, we explain how we dealt with mapping of alien species/populations. If you map every single alien population, you end up with a map that clouds the representation of the natural range of a species. You could solve that by using colours or shading to distinguish between natural and alien range parts, but then we would have to have accurate data on all alien populations. This data is lacking. Collecting it and presenting it in a fieldguide falls imho outside of the scope of such a book.


I liked the book! I read first pages here https://books.google.pl/books?id=OnicDA ... es&f=false before buying that book. I already surmised that introduced populations are not mapped because of difficulty in establishing bonduaries of distribution of these populations. My stepsister thought that the drawings were actual photos. She would like Ilian to draw her cat.

There is a little typo on page 30. There is "Sopramonte" instead of "Supramonte"

Not a typo. That's the correct Sardinian name. If you find one with 'u', that would be a typo.

As I'm slowly reading it, I may come back several times to tell you what I noticed.
For now, just noticed that the distribution map of C.austriaca is a bit too "mediterranean" along french coast where it is replaced by C.girondica.

By the way, there are also some data inside the big white hole of the Aquitaine region. These are "not so isolated" data and I won't be surprised if we find more in the future.

Well done!

Just some small comments on the distribution maps:
- Ophisops elegans doesn't occur on Astypalea
- Lacerta trilinieata also occurs in the central Cyclades
- Podarcis tauricus (ionicus) doesn't occur on Lefkada and adjoining mainland.

At last I have mine !
A great book indeed !

Juste a few remarks about what I know best : corsican herpetofauna.

I don't agree with the representation of Discoglossus montalentii. Why the same shape as Discoglossus sardus ?
Because the difference these two species is, the snout yes, but also the shape ! Long legs, much bulky body.

Apart from that nothing to say, the book is indeed a great tool for european naturalists ! Thanks !

Thanks, Robin!

About the Discos, there's something to be said for your point. Yet, imho (and probably more limited experience), the things you mention are subjective and at best only obvious when seeing them side by side, but (maybe even more importantly) age/size-dependent. Emphasising them in a drawing can easily mislead. But we'll think about it... ;)

In hand, the long legs of montalentii are a good characteristic for determination, some time even better than the snout.
I prefer to have the two before making a conclusion.
