Characterizing the collective personality of ant societies: aggressive colonies do not abandon their home.

Autor: Inon Scharf, Andreas P Modlmeier, Stephan Fries, Claire Tirard, Susanne Foitzik

Publikováno v: PLoS ONE, Vol 7, Iss 3, p e33314 (2012)

Animal groups can show consistent behaviors or personalities just like solitary animals. We studied the collective behavior of Temnothorax nylanderi ant colonies, including consistency in behavior and correlations between different behavioral traits.

Phenotypic plasticity of immune defence linked with foraging activity in the ant Cataglyphis velox

Autor: Claire Tirard, A. Bocher, Claudie Doums

Publikováno v: Journal of Evolutionary Biology. 20:2228-2234

Because immune defences are costly, life-history theories predict a modulation of immune investment according to its potential benefits. Social insects provide interesting models since infection risk may vary among individuals within a colony. In par

REPRODUCTIVE CONFLICTS AFFECT LABOR AND IMMUNE DEFENSE IN THE QUEENLESS ANT DIACAMMA SP. 'NILGIRI'

Autor: Laurence Millot, Aurélie Bocher, Claudie Doums, Claire Tirard

Publikováno v: Evolution. 62:123-134

In many species of social Hymenoptera, totipotency of workers induces potential conflicts over reproduction. However, actual conflicts remain rare despite the existence of a high reproductive skew. One of the current hypotheses assumes that conflicts

The outcome of coevolutionary interactions is predicted to vary across landscapes depending on local conditions and levels of gene flow, with some populations evolving more extreme specializations than others. Using a globally distributed parasite of

Population genetics of the common guillemot, Uria aalge, in the North Atlantic: geographic impact of oil spills

Autor: Thierry Boulinier, Léa Riffaut, Karen D. McCoy, Vicki L. Friesen, Claire Tirard

Publikováno v: Marine Ecology Progress Series. 291:263-273

The population genetic structure of a species can be an important conservation tool informing us about the potential for genetic loss and the capacity for species recovery. Depending on the nature of population subdivision, it can also provide a mean

Ecological impact of the 'Erika' oil spill: Determination of the geographic origin of the affected common guillemots

Publikováno v: Aquatic Living Resources. 17:369-377

Between 80 000 and 150 000 marine birds wintering in the Bay of Biscay were killed during the "Erika" oil spill. Three complementary studies were conducted to investigate the geographic origins of these birds. The common guillemot, Uria aalge, repres

Host specificity of a generalist parasite: genetic evidence of sympatric host races in the seabird tick Ixodes uriae

Autor: Claire Tirard, Thierry Boulinier, Karen D. McCoy, Yannis Michalakis

Publikováno v: Journal of Evolutionary Biology. 14:395-405

Due to the close association between parasites and their hosts, many ‘generalist’ parasites have a high potential to become specialized on different host species. We investigated this hypothesis for a common ectoparasite of seabirds, the tick Ixo
