Frogs can see the forest edge

Laure Schneider-Maunoury (contact: lschneid@clipper.ens.fr) has been visiting our research lab (F.E.C., Silwood Park Campus, Imperial College London, UK) since February 2014. Laure is doing a Master’s degree in Ecology, École Normale Supérieure, Paris, France. And she has chosen amphibians and reptiles as and their responses to the edge (created by forest fragmentation) for her graduate project.

Her main research questions tackled the unknown. Amphibians and reptiles, despite being considered as good indicators of environmental changes, have been poorly studied compared to other vertebrates.

(Question 1) Can we effectively detect the effect of forest edge on patterns of abundance distribution of reptile and amphibian populations?

(Question 2) What relationship is there between the ecological traits of a species and its response to fragmentation?

Her analyses, using Vero’s new algorithm for delineating fragments and identifying the edge ‘zone’ from continuous tree cover maps created by Hansen et al. (2013), clearly show:

There is an edge effect. This edge effect can be far-reaching. And certain species traits appear to be linked to these edge responses.

So watch out for her report at this webpages.

Thank you Laure.

PS: Laure will be around until mid-June and then return to Paris to defend her project.
