The effects of temperature and dispersal on species diversity in natural microbial metacommunities

Parain, Elodie C. ; Gray, Sarah M. ; Bersier, Louis-Félix

In: Scientific Reports, 2019, vol. 9, no. 1, p. 18286

Dispersal is key for maintaining biodiversity at local- and regional scales in metacommunities. However, little is known about the combined effects of dispersal and climate change on biodiversity. Theory predicts that alpha-diversity is maximized at intermediate dispersal rates, resulting in a hump-shaped diversity-dispersal relationship. This relationship is predicted to flatten when...

Increased temperature disrupts the biodiversity–ecosystem functioning relationship

Parain, Elodie C. ; Rohr, Rudolf P. ; Gray, Sarah M. ; Bersier, Louis-Félix

In: The American Naturalist, 2018, vol. 193, no. 2, p. 227–239

Gaining knowledge of how ecosystems provide essential services to humans is of primary importance, especially with the current threat of climate change. Yet little is known about how increased temperature will impact the biodiversity–ecosystem functioning (BEF) relationship. We tackled this subject theoretically and experimentally. We developed a BEF theory based on mechanistic population ...

Mismatch in microbial food webs: predators but not prey perform better in their local biotic and abiotic conditions

Parain, Elodie C. ; Gravel, Dominique ; Rohr, Rudolf P. ; Bersier, Louis-Félix ; Gray, Sarah M.

In: Ecology and Evolution, 2016, vol. 6, no. 14, p. 4885–4897

Understanding how trophic levels respond to changes in abiotic and biotic conditions is key for predicting how food webs will react to environmental perturbations. Different trophic levels may respond disproportionately to change, with lower levels more likely to react faster, as they typically consist of smaller-bodied species with higher reproductive rates. This response could cause a...
