Data from: Moderation is best: effects of grazing intensity on plant-flower visitor networks in Mediterranean communities

Amparo Lázaro, Thomas Tscheulin, Jelle Devalez, Georgios Nakas, Anastasia Stefanaki, Effie Hanlidou & Theodora Petanidou
The structure of pollination networks is an important indicator of ecosystem stability and functioning. Livestock grazing is a frequent land use practice that directly affects the abundance and diversity of flowers and pollinators and, therefore, may indirectly affect the structure of pollination networks. Here we studied how grazing intensity affected the structure of plant-flower visitor networks along a wide range of grazing intensities by sheep and goats, using data from 11 Mediterranean plant-flower visitor communities...

Data from: Spatial averaging and disturbance lead to high productivity in aquatic metacommunities

Evangelia Smeti, Daniel L. Roelke & Sofie Spatharis
Dispersal in heterogeneous ecosystems, such as coastal metacommunities, is a major driver of diversity and productivity. According to theory, both species richness and spatial averaging shape a unimodal relationship of productivity with dispersal. We experimentally tested the hypothesis that disturbances acting on local patches would buffer the loss of productivity at high dispersal by preventing synchronized species oscillations. To simulate these disturbances, our experimental assemblages involved species that self-organized in isolation under three inflow pulsing...
