About

Ali_PepperI am a CNRS researcher based at the University of Montpellier. My work looks mostly at the evolutionary ecology of host-parasite interactions across a variety of model systems. Recently I have also been dabbling in sex allocation.

Coinfection and parasite evolution

Coinfection can have very different consequences for parasite evolution compared to single infections. A current project is looking at parasite evolution in coinfections, comprising different spider mite species and plant viruses, on tomato host plants. The interactions between these different parasite species in the within-host environment are either competitive or facilitative, which may have different consequences for parasite virulence and transmission evolution. This is being investigated using selection experiments.

Sex allocation

Local mate competition (LMC), when mating occurs between the offspring of one or a few females, can select for female biased offspring sex ratios to reduce competition between brothers for mates, and increase the number of mates.
