The genetic Allee effect: a unified framework for the genetics and demography of small populations

Autor: Gloria M. Luque, Chloé Vayssade, Benoît Facon, Thomas Guillemaud, Franck Courchamp, Xavier Fauvergue

Publikováno v: Ecosphere, Vol 7, Iss 7, Pp n/a-n/a (2016)

Abstract The Allee effect is a theoretical model predicting low growth rates and the possible extinction of small populations. Historically, studies of the Allee effect have focused on demography. As a result, underlying processes other than the dire

Inbreeding depression in a parasitoid wasp with single-locus complementary sex determination.

Autor: Chloé Vayssade, Céline de Fazio, Bastien Quaglietti, Alexandra Auguste, Nicolas Ris, Xavier Fauvergue

Publikováno v: PLoS ONE, Vol 9, Iss 6, p e97733 (2014)

Inbreeding and inbreeding depression are key processes in small or isolated populations and are therefore central concerns for the management of threatened or (re)introduced organisms. Haplodiploid species of the order Hymenoptera have a particular s

Sex determination is ruled by haplodiploidy in Hymenoptera, with haploid males arising from unfertilized eggs and diploid females from fertilized eggs. However, diploid males with null fitness are produced under Complementary Sex Determination (CSD),

The response of life-history traits to a new species in the community: a story of Drosophila parasitoids from the Rhône and Saône valleys

Autor: Joan van Baaren, Véronique Martel, Xavier Fauvergue, Jacques J. M. van Alphen, Joffrey Moiroux, Chloé Vayssade

Publikováno v: Biological Journal of the Linnean Society. 107:153-165

In the present study, we investigated the evolution of life-history traits in the main species of a community, after the arrival of a new competitor. Two parasitoid species, Leptopilina heterotoma and Asobara tabida, are present throughout the Rhone

Background Single-locus complementary sex determination (sl-CSD), which occurs in some insects of the order Hymenoptera, imposes a heavy genetic load that can drive small populations to extinction. The core process in these species is the development

National audience; Un effet Allee elementaire se definit comme la depression de composantes de la fitness individuelle due a une baisse d’effectif de la population. Une consequence possible est une baisse du taux d’accroissement. Il s’agit alor
