Neighbouring sites (test and burnt ones) were used differently by species: some of them colonised several sites while others were restricted to a single site over the 4 years. Generalist species, as well as some specialist species, were favoured by this new situation, leading to an increased ...
First, disturbed habitats often favor opportunistic/generalist species which happen to be reservoirs for hemorrhagic fever viruses. Second, through a process called the dilution effect, in communities of lowering rodent diversity, more and more virus transmission events (aggressive encounters) occur within...
We have characterized the MHC class I diversity in 116 Panamanian Seba's short-tailed bats (Carollia perspicillata), a widely distributed, generalist, neotropical species. We have detected a remarkable individual and population-level diversity of MHC class I genes, with between seven and 22 alleles...
Phytosterol metabolism and absorption in the generalist grasshopper, Schistocerca americana (Orthoptera: Acrididae) A series of experiments, using GLC, RP-HPLC, and GC-MS techniques, were performed to examine the metabolic fate and absorption of different dietary sterols...

Measuring the influence of diet variability is especially important for species with substantial ontogenetic variation, such as generalist predators, in which juveniles often target smaller and lower trophic level prey groups than adults23. Similarly, it is important to consider ontogenetic diet shifts fo...
Currently, the database contains 1170 distinct avian immune genes with canonical gene symbols and 612 synonyms across 363 bird species. While the command-line interface readily integrates into bioinformatics pipelines, the intuitive web front-end with download functionality offers sophisticated search ...
In this study, we examined the potential of an iterative process of genetic assignment to separate specimens from distinct (e.g. species, populations) natural groups. Five loci with extensive overlap in allele distributions between species were used for the iterative process. Samples were randomly ...

Small patches are also more exposed and thus more vulnerable to adverse weather and potential effects of climate change. These conditions may be less problematic for generalist species than for specialists. Using insectivorous woodland birds (great tits and blue tits) as an example, we demonstrate ...
