Request: Crenicichla Revision, Ploeg, 1991

[Nuchal Man]

Know it's a long shot that anyone will have a pdf of this monograph, but if anyone does could you please send it my way. Need it for a project and unfortunately the closest copy to me is a good 10-12 hour drive.

Ploeg, Alex. 1991. "Revision of the South American cichlid genus Crenicichla Heckel, 1840, with description of fifteen new species and consideration on species groups, phylogeny and biogeography (Pisces, Perciformes, Cichlidae).".Univ. Amsterdam, Netherlands. pp. 1-153

Thanks,
Sam

hey Sam,

Ploeg's dissertation was originally not pubished as a PDF. Even Ploeg himself had to do with a copy with very bad B/W pictures. So I had the pleasure (and opportunity) at the time to create a better copy, using all original colour pictures provided by him. Only three copies were made, one of which I own myself.

If you have any specific questions, I'll be glad to try and help you, although copying the whole thing to PDF would probably be too big a task.

Hi Willem,

I'm actually doing a little morphometric study for a school project, so pictures of the specimens (of the species decribed in the paper or of previously described species before the paper) would be great. It's very hard to find good lateral photographs of preserved Crenicichla (thank god for some of the newer papers with nice pictures along with the descriptions).

I got a copy of the paper sent to me by Ingo (Thanks Ingo!), but like you said, unfortunately the pictures are not of the best quality.

Thanks,
Sam

OK. Let me see what I can do.

You're welcome, Sam. Indeed the copies circulated in Germany do not include color plates (actually the pictures are bad). So, it is good to know that you are possessing a better print, Willem.

I was wondering if such"Academisch Proefschrift" is validly published in the sense of the ICZN. But I have learned that - same in Germany - academic thesis are count as published by definition in the Netherlands. So far I know thesis are not automatically treated as published in the Anglo-American countries.

You know what really surprised me was the fact that even the author wasn't able to get a decent copy of his own work. A shame to the University, I would say. But then, this may be a worldwide problem. I have a copy of the almost forgotten Cichocki thesis (1979) and that is almost impossible to read (at some points).

Dear all. Hi Willem.
Well, I think the better way would have been if he (Ploeg) made his results available by a publication in a journal. But then he has to be more precise about the methods used to construct his biogeographic summary. And – for sure – he would be in need to give more convincing evidences for the new taxa created by him.
''The relatively recent revision of Crenicichla by Ploeg (1991), though an important contribution, is unfortunately plagued with several shortcomings and certainly cannot be considered a definitive monograph of the systematics of the genus.'' Varella et al (2012).
