Ecological constraints coupled with deep-time habitat dynamics predict the latitudinal diversity gradient in reef fishes

Gaboriau, Théo ; Albouy, Camille ; Descombes, Patrice ; Mouillot, David ; Pellissier, Loïc ; Leprieur, Fabien

In: Proceedings of the Royal Society B: Biological Sciences, 2019, vol. 286, no. 1911, p. 20191506

We develop a spatially explicit model of diversification based on palaeohabitat to explore the predictions of four major hypotheses potentially explaining the latitudinal diversity gradient (LDG), namely, the ‘time-area’, ‘tropical niche conservatism’, ‘ecological limits’ and ‘evolutionary speed’ hypotheses. We compare simulation outputs to observed diversity gradients in the...

Comparing species interaction networks along environmental gradients: Networks along environmental gradients

Pellissier, Loïc ; Albouy, Camille ; Bascompte, Jordi ; Farwig, Nina ; Graham, Catherine ; Loreau, Michel ; Maglianesi, Maria Alejandra ; Melián, Carlos J. ; Pitteloud, Camille ; Roslin, Tomas ; Rohr, Rudolf ; Saavedra, Serguei ; Thuiller, Wilfried ; Woodward, Guy ; Zimmermann, Niklaus E. ; Gravel, Dominique

In: Biological Reviews, 2018, vol. 93, no. 2, p. 785–800

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...

Responses of coral reef fishes to past climate changes are related to life‐history traits

Ottimofiore, Eduardo ; Albouy, Camille ; Leprieur, Fabien ; Descombes, Patrice ; Kulbicki, Michel ; Mouillot, David ; Parravicini, Valeriano ; Pellissier, Loïc

In: Ecology and Evolution, 2017, vol. 7, no. 6, p. 1996–2005

Coral reefs and their associated fauna are largely impacted by ongoing climate change. Unravelling species responses to past climatic variations might provide clues on the consequence of ongoing changes. Here, we tested the relationship between changes in sea surface temperature and sea levels during the Quaternary and present-day distributions of coral reef fish species. We investigated...

Community‐level plant palatability increases with elevation as insect herbivore abundance declines

Descombes, Patrice ; Marchon, Jérémy ; Pradervand, Jean-Nicolas ; Bilat, Julia ; Guisan, Antoine ; Rasmann, Sergio ; Pellissier, Loïc

In: Journal of Ecology, 2017, vol. 105, no. 1, p. 142–151

Plants protect themselves against herbivore attacks through a myriad of physical structures and toxic secondary metabolites. Together with abiotic factors, herbivores are expected to modulate plant defence strategies within plant assemblages. Because the abundance of insect herbivore decreases in colder environments, the palatability of plants in communities at higher elevation should shift...

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...
