Background Coexistence of sexual and asexual populations remains a key question in evolutionary ecology. We address the question how an asexual and a sexual form of the parasitoid Venturia canescens can coexist in southern Europe. We test the hypothe

Consistent individual differences in behaviour, also called behavioural types, are often observed in animal populations and can correlate to form behavioural syndromes. Behavioural types and syndromes have consequences in various fields of ecology, f

International audience; Mating failures at low density – a common type of Allee effect – can reduce the per capita reproductive rate and, if severe enough, doom small populations to extinction. Parasitoids frequently undergo low densities trigger

Animals adjust their behaviour in response to changing environmental conditions. This form of plasticity can result from animals’ experience and their capacity to update information about their habitat. In the context of optimal foraging in patchy
