Anuran amphibians have emerged as model vertebrates for the study of kin recognition
mechanisms. Larvae of most species reported to date discriminate between kin and non-kin …

INCLUSIVE fitness theory predicts that organisms can often increase their fitness by hel**
relatives1. Indeed, many animals modify their behaviour towards kin in a fashion consistent …

Kinship underlies many facets of vertebrate sociality. Yet vertebrate societies rarely consist
exclusively of kin. Typically, individuals interact both with kin and non-kin in numerous and …

Theory and empirical evidence show that intraspecific competition can drive selection
favouring the use of novel resources (ie niche expansion). The evolutionary response to …

Observations on the means, variances, and covariances of quantitative traits across hybrid
zones can give information similar to that from Mendelian markers. In addition, they can …

Dispersal is a central component of life history evolution. An increasing number of studies
suggest that spatiotemporally variable environments may promote the evolution of “dispersal …

Bombina variegata is a temporary pond breeder, strictly protected under the Habitat
Directive (Annex II). The persistence of its populations highly depends on the ability of …

Inclusive fitness theory predicts that organisms can increase their fitness by hel** or not
harming relatives, and many animals modify their behavior toward kin in a manner …

Growth and metamorphosis of the toad Bufo melanostictus was studied by rearing tadpoles
of different sibships in isolation or in groups of siblings and nonsiblings (mixed rearing) …

In vertebrates, little is known of kin recognition systems and their plasticity. Even in well-
studied anuran larvae (tadpoles), the determinants and effects of prior experience have not …
