Female and male reproductive traits co-evolve through pre- and post-copulatory sexual selection and sexual conflict. Although males typically transfer many sperm during copulation, only a small proportion reach the fertilization site because females

In recent years, increases in the urban fox population have been observed in many countries of the Northern Hemisphere. As a result, Echinococcus multilocularis has entered the urban environment. Because of a possible increased risk for alveolar echi

Precise mechanisms underlying sperm storage and utilization are largely unknown, and data directly linking stored sperm to paternity remain scarce. We used competitive microsatellite PCR to study the effects of female morphology, copula duration and

La variation dans les caractéristiques des gamètes peut dépendre de plusieurs facteurs génétiques et environnementaux, tels que l'instabilité du développement causée par la consanguinité, les perturbations (bruit) dans le développement dura

The shell form of aquatic gastropods can vary among closely-related species or populations according to the intensity of water movement in a habitat or to other environmental factors." Freshwater snails can also adapt to local conditions by altering

Summary Because the developmental performance of a genotype can vary substantially depending on the conditions to which it is exposed, mothers are known to exercise strong choice concerning oviposition sites. Females potentially adjust the provisioni

Temperature can affect the performance of insects through its influence on enzyme function. We report a series of laboratory and field experiments investigating the putatively adaptive temperature-dependent effects of phosphoglucomutase (pgm) genotyp

Substantial inter- and intraspecific variation is found in reproductive traits, but the evolutionary implications of this variation remain unclear. One hypothesis is that natural selection favours female reproductive morphology that allows females to

The Hamilton & Zuk hypothesis (Hamilton & Zuk 1982) was tested in the European minnow, Phoxinus phoxinus (L.), where the male breeding characters include tubercles, which are horny growths on the skin of the head, and a bright red abdomen. Two tremat
