The biotic and abiotic contexts of ecological selection mediate the dominance of distinct dispersal strategies in competitive metacommunities

Author(s): Khattar G; Savary P; Peres-Neto PR;

While the influence of dispersal on ecological selection is the subject of intense research, we still lack a thorough understanding of how ecological selection operates to favour distinct dispersal strategies in metacommunities. To address this issue, we de ...

Reciprocal inhibition and competitive hierarchy cause negative biodiversity-ecosystem function relationships

Author(s): D' Andrea R; Khattar G; Koffel T; Frans VF; Bittleston LS; Cuellar-Gempeler C;

The relationship between biodiversity and ecosystem function (BEF) captivates ecologists, but the factors responsible for the direction of this relationship remain unclear. While higher ecosystem functioning at higher biodiversity levels ('positive BEF& ...

Decline in wild bee species richness associated with honey bee (Apis mellifera L.) abundance in an urban ecosystem

Author(s): MacInnis G; Normandin E; Ziter CD;

The spatial heterogeneity of urban landscapes, relatively low agrochemical use, and species-rich floral communities often support a surprising diversity of wild pollinators in cities. However, the management of Western honey bees (Apis mellifera L.) in urba ...
