Pagano, Alain, and Pierre Joly (1998) Limits of the morphometric method for taxonomic field identification of water frogs. Alytes 16:3-4.
Abstract: Taxonomic identification of the water frogs has evolved since hybridogenesis has been revealed within the Rana esculenta complex. Although the study of protein polymorphism has proved robust in taxonomic information, morphometric measurements are currently used despite of some limits. By comparing results obtained with these two techniques, this study shows that morphometry is does not always provide a decisive taxonomic information for field identification. In the three populations studied, in the mid-Rhone floodplain, the morphs of Rana ridibunda and the hybrid R. kl. esculenta greatly overlap in morphometrical characters.
Plenet, S. and P. Joly, and A. Pagano (1998) Is habitat requirement by an oxygen-dependent frog (Rana ridibunda) governed by its larval stage? Arch. Hydrobiol. (1998) 143/1: 107-119.
According to the literature and to our own experience, R. ridibunda is
absent from ponds with occasionally low oxygen concentrations. We tested
the effects of stochastically fluctuating oxygen concentration on tadpole
survival and growth under laboratory conditions. Two experimental
treatments (constant and fluctuating oxygen regimes) were arranged in a
factorial design with three populations of R. ridibunda.
Water frog bibliographyHansjürg Hotz is providing his water frog bibliography, he is managing his bibliography with Endnote on a Mac, and we will upload files for Macintosh, Windows, and UNIX machines of a file-format which are readable with any ASCII capable editor, but these files use special characters for the specified systems, the UNIX archive is using a standard ISO8859-1 characterset. The files are in a format named REFER which can be read almost by all bibliography programs (we are using Endnote's extension of the REFER format). If you encounter problems in downloading the bibliography or have special need for conversion to more exotic formats send email to Peter Beerli. If you have additional citations, preferrably in the same format, please donate them back to Hansjürg Hotz by email, so that we can keep all of us up to date.
