BIOFRAG Index – Background and News

Quantifying biodiversity response to forest fragmentation worldwide.

News:

We are currently running the code for the data on birds in fragmended forests of Ghana (ID001; data by Dr Ben Phalan, University of Cambridge), where sampling was carried out in selected areas of forests, oil palms and farms.

Furthermore, the code is currently adapted to (1) generate a BIOFRAG estimate quantifying response of individual species to fragmentation, (2) improve model algorithms (e.g. include a jacobian matrix approach for sensitivity analysis in the beta logistic regression, nad (3) include the Sorensen Similarity Index (beside the currently used Bray Curtis Index) as measure of species turnover  between sites (beta diversity), for those sites where only presence-absence data are available.
