Environmental stoichiometry mediates phytoplankton diversity effects on communities’ resource use efficiency and biomass

Miriam Gerhard, Alexandra Schlenker, Helmut Hillebrand & Maren Striebel
Positive biodiversity-ecosystem functioning (BEF) relationships are predicted to increase in strength when high environmental variability allows for complementarity between resource use strategies in diverse communities. This environmental variability can be represented by spatial or temporal variation in nutrient ratios, but resource use efficiency (RUE) and therefore biomass build up of primary producers might be restricted when nutrient ratios are highly imbalanced (i.e., limitation by one nutrient and beyond optimal ratios for growth). Whereas the linkages...

Legacy effects of seed dispersal mechanisms shape the spatial interaction network of plant species in Mediterranean forests

Antonio Perea, Thorsten Wiegand, José Garrido, Pedro Rey & Julio M. Alcantara
1. Seed dispersal by frugivores plays a key role in structuring and maintaining tree diversity in forests. However, little is known about how the spatial legacy of seed dispersal and early recruitment shapes spatial patterns and the spatial interaction network of plant species in mature forest communities. 2. We analysed two fully mapped mixed Pine-Oak forest communities using spatial point pattern analysis to determine (i) the detailed structure of the intraspecific spatial patterns of saplings...

Data for: Winners and losers over 35 years of dragonfly and damselfly distributional change in Germany

Aim: Recent studies suggest insect declines in parts of Europe; however, the generality of these trends across different taxa and regions remains unclear. Standardized data are not available to assess large-scale, long-term changes for most insect groups but opportunistic citizen science data is widespread for some. Here, we took advantage of citizen science data to investigate distributional changes of Odonata. Location: Germany Methods: We compiled over 1 million occurrence records from different regional databases. We...
