Frogs, ponds and rivers

The paper “The interplay of dispersal limitation, rivers and historical events shapes the genetic structure of an Amazonian frog” by Fouquet et al. [1], realized within the Ecological Genetics lab at EcoFoG (as an interanational collaboration between INRA, CSIC Barcelona, Sao Paulo University, CNRS and the University of Mississippi) has now been accepted for publication in the Biological Journal of the Linnean Society. This paper deals with barriers to migration and gene flow in the common Amazonian Adenomera frogs. It shows that genetic diversity is highly structured on short distances in this anuran species laying eggs in temporary ponds, and that rivers represent formidable barriers to dispersal. These results contribute to the understanding of how biodiversity is spatially structured in tropical forests. This paper follows a previous technical paper (Fouquet et al. 2009 [2]) that described the genetic markers used in this population-genetic study.
