Rapid environmental change is the major challenge that most biota must confront in the near future. Ectotherm animals might be particularly at risk since temperature affects the sex of various species of fish, amphibians and reptiles. In some instances, this is known to translate into changes in the adult sex ratio (ASR).
As a network of ecologists, physiologists and computer scientists working together, we will build a dataset at the global scale by assembling, harmonizing, and distributing published and unpublished data on the ASR of ectotherms belonging to teleost fishes, amphibians, crocodiles, turtles, and squamate reptiles, complemented by a wide range of metadata – methodological and environmental information (mainly temperature).
Complementarity of competences in all members of the FARSEX group
More precisely, the dataset will provide a common scheme for merging georeferenced observations of populations for which we have information on 1) ASR in the wild, 2) sex-reversal of individuals in the wild and 3) sex-determination system of the species. All this information will be placed, and later studied, in a climate change context.
