AMPLI GAMMA - Landscape planning and gamma multi-diversity

Objectives

How can landscapes be organised to better protect multi-taxonomic diversity?

In a global context of loss and fragmentation of natural habitats, changes in land use and management practices, the consortium will address the following two questions

• What is the link between landscape compositional and configurational heterogeneity and multi-taxonomic specific and functional diversity at different spatial scales?
• How is multi-taxonomic gamma-specific diversity influenced by the configuration and composition of the landscape mosaic, and what are the relative contribution of different types of management (or ecosystem types resulting from management) to this gamma-specific diversity?

These questions are central to understand and analyse the role of management types on biodiversity in European anthropogenised landscapes, and to determine landscape organisation that would be more favourable to biodiversity.

Approaches

These questions will be addressed through an empirical approach sampling different landscapes and biogeographical regions: predominantly forested landscapes, predominantly agricultural landscapes (including vineyards), aquatic landscapes and mixed landscapes, trying to cross-reference landscape types and biogeographical regions as much as possible.

The first task of the consortium will be to better formalise and refine the working hypotheses through an in-depth literature review on the link between landscape heterogeneity and biodiversity, in particular detailing the mechanisms that maintain gamma diversity in heterogeneous landscapes.

The second phase will focus on the sites and management gradients to sample, taking into account the current issues in forest management, agroecology and lakes, and the geospatial data available to characterise landscape composition and structure (satellite or aerial images, BDcarto®, Cesbio OSO layer, RPG).

A third focus will be on the sampling strategies to estimate multi-taxonomic gamma-specific diversity, as sampling gamma specific richness raises several methodological issues (species accumulation, detectability, etc.).
