For example, our results suggest that populations of cursorial predators (such as spotted hyaenas) are expected to fare better than populations of ambush predators (such as African lions) in African ecosystems that will be characterised by an aridification. We discuss how species traits influence the relative importance of the different sources of vulnerability. We show that predictions on how predator abundance responds to climate fluctuations differ depending on how climate influences prey vulnerability (habitat characteristics vs. We account for prey body condition and habitat effects on prey vulnerability to predation. ![]() ![]() In this theoretical work, we explore, with large mammals of African savannas in mind, how the interplay between climate-induced changes in prey abundance and climate-induced changes in prey vulnerability affects the immediate and long-term responses of predator populations. However, field studies have shown that prey vulnerability is a key feature determining the outcome of predator–prey interactions, which also varies with climatic conditions, via changes in prey body condition or in habitat characteristics (e.g. Most animals experience predation, and a number of models have investigated how climate fluctuations can influence predator–prey dynamics by affecting prey abundance through changes in resource availability. 5Wildlife Conservation Research Unit, Department of Zoology, Recanati-Kaplan Centre, Oxford University, Oxford, United KingdomĬlimate changes affect the distribution and abundance of organisms, often via changes in species interactions.4CNRS Hwange Environmental Research Development Program, Long-Term Socio-Ecological Research site France, Zone Atelier “Hwange”, Dete, Zimbabwe.3Mammal Research Institute, Department of Zoology and Entomology, Faculty of Natural and Agricultural Sciences, University of Pretoria, Pretoria, South Africa.Paul Valéry Montpellier 3, Montpellier, France 1Laboratoire de Biométrie et Biologie Evolutive, UMR 5558, Centre National de la Recherche Scientifique, Université Lyon 1, Université de Lyon, Villeurbanne Cedex, France. ![]() Aïssa Morin 1* Simon Chamaillé-Jammes 2,3,4 Marion Valeix 1,4,5
