Amphibian diversity changes on local and regional scales. What influence has logging, forest fragmentation and agriculture on amphibian diversity?

Short description: We investigate how human impact influences amphibian diversity and the processes that structure amphibian communities on the local and regional scale, both in savannah (agriculture) and forest areas (logging, fragmentation). To assure comparability of the collected data we apply a standardized monitoring protocol (www.biozentrum.uni-wuerzburg.de/zoo3/roedel_kl.htm), developed in cooperation with E08 and W09.

Separating local and regional reasons for amphibian decline from global ones:

Short description: Our analysis of demographic population structure of selected species (functional types) forms the basis for the use of amphibians as "population indicators". Our biodiversity monitoring on three different levels - communities, intraspecific, between populations allow for the rapid assessment of changes with three levels of sensitivity. Research within BIOTA-West observatories guarantee a maximum of comparability with other biodiversity assessments of BIOTA-West. Standardized methodology guarantees comparability and combined analysis on a global level.

Amphibians as surrogate species for biodiversity monitoring and modeling of amphibian diversity changes:

Short description: With our field data and remote sensing data (e.g. land cover, climate, altitude etc.) we will develop species-specific and habitat-specific assemblage models. On these basis we will model and predict changes in amphibian diversity due to ongoing land use like logging and fragmentation as well as to long term climate changes. Our model approach will be directly incorporated into a comparative analysis of respective questions dealt with in W01, W02, W09 and W11.
