Well, that's what happens when you get an expert! Peter knows that books can be wrong, and he (and I) both know that authors cite each other - and so in the literature things happen like somebody once collected some snakes of a certain species in one place that were mostly female, and in another that were mostly male, and -without sexing them- decided that there were size variations when actually the variations were in the ''gender'' collected. That fact - just the sizes, nothing about gender since the animals were never sexed (nobody thought about it) -gets published and then cited, so that , over the years, 10 sources that confirm it are all citing citations of the same flawed study. Often that's not even done in a way that is obvious, unless every reference is fully read and checked in every one of the 10 sources, because the latest source cites a previous review that includes the flawed study, rather than the flawed study itself. So looking at the article you have written, statements about geographic size variations of populations are made citing ONLY a couple of maximum size specimens, that's meaningless without knowing more- at least the genders and that's only the beginning. | Well, that's what happens when you get an expert!

Let's wait to see what else he has to say. Remember please, Peter is not doubting your scholarship, frankly, he doesn't care about that - what he cares about are the ''snakes'', and that what is said is true. Myrna Watanabe (his wife, who is now an editor at CZ) read in many books what the American alligator did in its nesting habits before she proved most of them wrong by actually observing nesting females and saw how they actively broke open the nests to care for their hatchlings (among other things).

Peter (as is partly detailed in his autobiographical book "You should be in a zoo") has dealt with people all over the world who keep venomous snakes despite the laws (or in some places, despite the danger - there are no laws) and has had to use his Zoo budgets to send expensive antivenin to people who were bit by their captives and then, had to endure his own keepers and himself being left without that particular antivenin being availabe while they carried out their legitimate duties of caring for venomous specxies. He is ''much'' more interested in the biological questions than simple description although he knows as much as anybody about the descriptions.

Comments from Peter Brezaitis
1) Vipera berus is a thick bodied snake relative to other species of snakes in Europe, however as compared to other species of vipers such as Bitis gabonica and Bitis Arietans it is a moderately thick bodied snake.
2)"Adults grow to 60 cm in length with an average of 55 cm. Maximum size varies per region. The largest -- over 90 cm -- are found in Sweden; specimens of 104 cm have been observed there on two occasions. In France and Great Britain, the maximum size is 80-87 cm.[2]" Is this important? The average size is important, the reference needs to be checked. If males are larger than females, and the size difference between males and females is important. Are the largest animals males or females" Were they sexed? Point is that there sexual dimorphism.
- Peter has gone off now, will print out article and e-mail in comments which I will append. Nancy Sculerati 18:59, 22 April 2007 (CDT) PS- for "who is Peter Brezaitis?" see ISBN 0-8129-6790-9
- Interesting fellow; he writes well, so let's hope he decides to help out! I'll add comments about body build and sexual dimorphism: with V. berus, the females are always relatively larger and heavier than the males (sexing snakes is not that difficult). As for mentioning the maximum size(s), why not? It's to give readers a clear indication of where reality stops and fantasy begins. The corresponding (in-line) references are always at the end of each sentence or paragraph. --Jaap Winius 20:08, 23 April 2007 (CDT)
He'll be making more comments, but his point about maximum size and geographic range is partly that we have to check that the same sexwas compared at different portions of the range, since females are large, so if females from one area are compared to males of another (or nobody checked the sex, they just recorded a few snakes' length) that the data is meaningless. He's a cool guy, he left me a copy of "You belong in a zoo"which I am reading now, it's not only a great book- it includes the folks that I studied under years ago. Nancy Sculerati 20:17, 23 April 2007 (CDT)
- It's difficult for me to be sure that the size/sex information is correct; all I can do is take Mallow, Ludwig and Wilson's word for it (the authors of the book I used as a reference for that section). However, the average size of 50-60 cm, as well as the point that the males are generally smaller than the females, also corresponds with several other books I have. --Jaap Winius 04:50, 24 April 2007 (CDT)
Well, that's what happens when you get an expert! Peter knows that books can be wrong, and he (and I) both know that authors cite each other - and so in the literature things happen like somebody once collected some snakes of a certain species in one place that were mostly female, and in another that were mostly male, and -without sexing them- decided that there were size variations when actually the variations were in the gender collected. That fact - just the sizes, nothing about gender since the animals were never sexed (nobody thought about it) -gets published and then cited, so that , over the years, 10 sources that confirm it are all citing citations of the same flawed study. Often that's not even done in a way that is obvious, unless every reference is fully read and checked in every one of the 10 sources, because the latest source cites a previous review that includes the flawed study, rather than the flawed study itself. So looking at the article you have written, statements about geographic size variations of populations are made citing ONLY a couple of maximum size specimens, that's meaningless without knowing more- at least the genders and that's only the beginning.

Remember please, Peter is not doubting your scholarship, frankly, he doesn't care about that - what he cares about are the snakes, and that what is said is true.
