Ecological conditions are likely to change with increasing urbanization, influencing the demography and size of animal populations. Although one of the most tightly linked species to humans, the house sparrow has been suffering a significant dec[...]

Predators impose strong selection on their prey, regulate prey populations and engage in coevolutionary interactions with their prey. The intensity of selection and the strength of coevolutionary interactions will depend on how stringent predato[...]

Adjusting breeding phenology to climate fluctuations can be problematic for migratory birds as they have to account for local environmental conditions on the breeding grounds while migrating from remote wintering areas. Predicting general respon[...]

Holes provide the safest nest sites for birds, but they are an underutilized resource; in natural forests there are usually more holes than birds that could use them. Some bird species could be prevented from nesting in holes because of their in[...]

Differential growth rate between males and females, owing to a sexual size dimorphism, has been proposed as a mechanism driving sex-biased survival. How parents respond to this selection pressure through sex ratio manipulation and sex-biased par[...]

Juvenile mortality is one of crucial drivers of life-history evolution, and predation is the main cause of nest loss in birds. Thus, understanding how nest predation and failure vary in nature is important for understanding life history evolutio[...]

Food accessibility and availability in the highly seasonal Arctic landscape can be restricted by snow cover and frozen substrate, particularly in early spring. Therefore, to determine how a long distance migratory herbivore forages in such a lan[...]

Animal collective patterns such as group size frequency distributions often show substantial intraspecific variation, suggesting low species-specific consistency. Here, we dissect intraspecific vs interspecific components of colony size variatio[...]

Comparing closely related species that live in different environments is a powerful way to understand selective pressures that influence life-history evolution. We examined a suite of life-history traits and parental care in neotropical buff-bre[...]

Sex-biased resource allocation in eggs is increasingly recognized as one strategy oviparous mothers can employ to invest differentially in one sex, depending on nutritional requirements. Previous studies have used egg size as an index of nutrien[...]

Inbreeding may impair an individual's immune system, render it more susceptible to disease and hence contribute to the extinction risk of small and isolated populations, as often found on islands. So far, surprisingly few studies have assessed t[...]
