Studies dealing with changes of biodiversity in time and space constitute an important part of biogeography, ecology and conservation biology. Areas of long-term climate stability are particularly interesting as they might have facilitated the s[...]

Structures built by animals, such as nests, mounds and burrows, are often the product of cooperative investment by more than one individual. Such structures may be viewed as a public good, since all individuals that occupy them share the benefit[...]

Adjustments in body composition over the annual cycle have been documented in many organs and muscle groups. Here we consider the nature and significance of intra-organ variation in the eared grebe Podiceps nigricollis stomach, a large and varia[...]

This paper compares the migratory movements of Iberian and central European satellite-tagged black storks Ciconia nigra moving to Africa across the Strait of Gibraltar. Results show that the populations differ in departure dates from breeding ar[...]

An advantage of huddling in the cold is that the individual animals involved can maintain body temperature while saving energy. Since house sparrows Passer domesticus biblicus store little fat, but inhabit relatively cold climates, we tested the[...]

Biogeographic barriers potentially restrict gene flow but variation in dispersal or vagility can influence the effectiveness of these barriers among different species and produce characteristic patterns of population genetic structure. The objec[...]

Diet strongly influences the chemistry of vertebrate soft and hard tissues. Bird bone and eggshell mineral preserve reliable records of prey consumption, even beyond the life of the predator, and analyses of hard tissues have usefully reconstruc[...]

Nest box provisioning is a common management tool intended to increase population size or stability of threatened birds, but its effectiveness is rarely assessed. The provisioning of nest boxes may lead to unexpected results if nest type imprint[...]

Adaptive sex allocation has frequently been studied in sexually size dimorphic species, but far less is known about patterns of sex allocation in species without pronounced sexual size dimorphism. Parental optimal investment can be predicted und[...]

Provisioning behavior in altricial birds is often used to measure parental investment and is assumed to have fitness consequences to the parents providing it, with the benefits outweighing the costs. Here we investigate the fitness costs and ben[...]

Sleep is ubiquitous in animals, but there is great inter- and intraspecific variation in the daily amount of sleep that is needed. Chronic sleep curtailment or experimental sleep deprivation are known to impair health and performance of individu[...]

The expression and impact of maternal effects may vary greatly between populations and environments. However, little is known about large-scale geographical patterns of variation in maternal deposition to eggs. In birds, as in other oviparous an[...]

Tradeoffs among demographic traits are a central component of life history theory. We investigated tradeoffs between reproductive effort and survival in female greater sage-grouse breeding in the American Great Basin, while also considering repr[...]
