Knowledge of species composition and their interactions, in the form of interaction networks, is required to understand processes shaping their distribution over time and space. As such, comparing ecological networks along environmental gradients represents a promising new research avenue to understand the organization of life. Variation in the position and intensity of links within networks...

Simulated shifts in trophic niche breadth modulate range loss of alpine butterflies under climate change

Descombes, Patrice ; Pradervand, Jean-Nicolas ; Golay, Joaquim ; Guisan, Antoine ; Pellissier, Loïc

In: Ecography, 2016, vol. 39, no. 8, p. 796–804

Species currently track suitable abiotic and biotic conditions under ongoing climate change. Adjustments of trophic interactions may provide a mechanism for population persistence, an option that is rarely included in model projections. Here, we model the future distribution, of butterflies in the western Alps of Switzerland under climate change, simulating potential diet expansion resulting...

Historical and contemporary determinants of global phylogenetic structure in tropical reef fish faunas

Leprieur, Fabien ; Colosio, Simona ; Descombes, Patrice ; Parravicini, Valeriano ; Kulbicki, Michel ; Cowman, Peter F. ; Bellwood, David R. ; Mouillot, David ; Pellissier, Loïc

Identifying the main determinants of tropical marine biodiversity is essential for devising appropriate conservation measures mitigating the ongoing degradation of coral reef habitats. Based on a gridded distribution database and phylogenetic information, we compared the phylogenetic structure of assemblages for three tropical reef fish families (Labridae: wrasses, Pomacentridae: damselfishes...

Plate tectonics drive tropical reef biodiversity dynamics

Leprieur, Fabien ; Descombes, Patrice ; Gaboriau, Théo ; Cowman, Peter F. ; Parravicini, Valeriano ; Kulbicki, Michel ; Melián, Carlos J. ; Santana, Charles N. de ; Heine, Christian ; Mouillot, David ; Bellwood, David R. ; Pellissier, Loïc

The Cretaceous breakup of Gondwana strongly modified the global distribution of shallow tropical seas reshaping the geographic configuration of marine basins. However, the links between tropical reef availability, plate tectonic processes and marine biodiversity distribution patterns are still unknown. Here, we show that a spatial diversification model constrained by absolute plate motions...
