Age-specific survival and recruitment of piping plovers Charadrius melodus in the Great Lakes region

Juvenile survival and age at first breeding (i.e. recruitment) are critical parameters affecting population dynamics in birds, but high levels of natal dispersal preclude measurement of these variables in most species. We used multi-state captur[...]

Patterns of genetic structure and gene flow among populations help us understand population dynamics and properly manage species of concern. Matrilineal mtDNA sequence data have been instrumental in revealing genetic structure at the intraspecif[...]

Intraspecific competition can influence refuelling at migration stopover sites. White-throated sparrows Zonotrichia albicollis have genetically-determined plumage morphs that differ in dominance behaviour and competitive abilities. This study ex[...]

Life history theory predicts an inverse relationship between annual adult survival and fecundity. Globally, clutch size shows a latitudinal gradient among birds, with south temperate species laying smaller clutches than north temperate species, [...]

Songbirds in seasonal environments often adjust their breeding strategy according to spatial or temporal changes in breeding conditions. Here we investigate how horned larks Eremophila alpestris, a multi-brooded songbird on the Tibetan Plateau, [...]

North-African house martins endure greater haemosporidian infection than their European counterparts

Afro-Palearctic migrant species are exposed to parasites at both breeding and over-wintering grounds. The house martin Delichon urbicum is one such migratory species facing high instances of blood parasite infection. In an attempt to determine w[...]
Article
Antagonistic processes between parasites and their hosts are hallmarks of evolutionary ecology. A group of parasites is adapted to feed on feather keratin. In doing so, they inflict a variety of costs on avian hosts by causing feathers to degrad[...]

Several non-mutually exclusive hypotheses predict adaptive variation in the offspring sex ratio. When conditions for breeding are adverse, parents are predicted to produce more offspring of the less costly sex to rear (the cost-of-reproduction h[...]

Miniaturized light-level geolocators may revolutionise the study of avian migration. However, there are increasing concerns that they might negatively affect fitness. We investigated the impact of two miniaturized geolocator models (SOI-GDL2.10,[...]

Risk taking decisions related to the unpredictability of resource availability (risk-sensitive foraging theory) have typically been explained by behavioral ecology and psychology approaches. However, little attention has been given to the physio[...]

Here we explore the environmental and geographical factors affecting the winter distribution of the black stork Ciconia nigra in the Iberian Peninsula, where an increasing number of individuals have remained to winter in the last two decades. We[...]

Species delimitation has important consequences for the management of endangered species. Species-level taxonomy in the genus Crypturellus (Tinamidae) has been based largely on plumage characters and species limits in several groups have been di[...]

In altricial birds, the quantity and quality of food provided by parents is a crucial determinant of nestling performance. Vitamin E is an important micronutrient with various physiological functions, including a positive role in the antioxidant[...]

Understanding how organisms adjust breeding dates to exploit resources that affect fitness can provide insights into impacts of climate change on avian demography. For instance, mismatches have been reported in long-distance migrant bird species[...]
