Habitat fragmentation and amphibian conservation: building a tool for assessing landscape matrix connectivity.
We have attempted modelling biological connectivity for a toad population in a floodplain in the combined framework of population dynamics and landscape ecology. We took advantage of the GIS packageExpand

Extra-pair paternity in the monogamous alpine marmot (Marmota marmota): the roles of social setting and female mate choice
Extra-pair paternity (EPP) can be influenced by both social setting and female mate choice. If evidence suggests that females try to obtain extra-pair copulations (EPCs) in order to gain geneticExpand

Social structure influences extra-pair paternity in socially monogamous mammals
Using the genetic estimates of paternity available for 22 species of socially monogamous mammals, we investigated the impact of the social structure and of the type of pair bonding on theExpand

Extra-pair paternity in alpine marmots, Marmota marmota: genetic quality and genetic diversity effects
Assuming that a male’s genetic characteristics affect those of his offspring, extra-pair copulation has been hypothesized to increase heterozygosity of the progeny—the “genetic compatibility”Expand

Genetic diversity-fitness correlation revealed by microsatellite analyses in European alpine marmots (Marmota marmota)
The relationship between individual genetic diversity and fitness-related traits are poorly understood in the wild. The availability of highly polymorphic molecular markers, such as microsatellites,Expand

The genetic similarity between pair members influences the frequency of extrapair paternity in alpine marmots
Extrapair paternity is widespread in birds and mammals. In particular, the alpine marmot, Marmota marmota, has a high frequency of extrapair paternity that seems to be explained by the geneticExpand

Sex-specific senescence in body mass of a monogamous and monomorphic mammal: the case of Alpine marmots
Sex-specific senescence has been commonly reported in highly dimorphic and polygynous species. However, whether between-sex differences in senescence occur in monogamous and monomorphic species isExpand

Contrasting patterns of selection acting on MHC class I and class II DRB genes in the Alpine marmot (Marmota marmota)
The major histocompatibility complex (MHC) genes code for proteins that play a critical role in the immune system response. The MHC genes are among the most polymorphic genes in vertebrates,Expand

Mate change in a socially monogamous mammal: evidences support the “forced divorce” hypothesis
Three main hypotheses have been proposed to explain mate switching in monogamous species: the "better option" hypothesis, the incompatibility hypothesis, and the "forced divorce" hypothesis. WeExpand

Are extra-pair young better than within-pair young? A comparison of survival and dominance in alpine marmot.
1. In socially monogamous species, females may seek extra-pair copulation to gain genetic benefits. In order to test this 'genetic quality' hypothesis, one must compare the performance of extra-pairExpand
