Sperm length variation as a predictor of extrapair paternity in passerine birds. [PDF]
PLoS ONE, 2010 The rate of extrapair paternity is a commonly used index for the risk of sperm competition in birds, but paternity data exist for only a few percent of the approximately 10400 extant species.

The presence of air sac nematodes in passerines and near-passerines in southern Germany
International Journal for Parasitology: Parasites and Wildlife, 2023 Major climatic changes in conjunction with animal movement may be associated with the spread of parasites and their vectors into new populations, with potentially important consequences for population persistence. Parasites can evolve to adapt to unsuitable ecological conditions and take up refuge within new host species, with consequences for the ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Animal‐mediated seed dispersal sustains plant diversity and ecosystem functioning, particularly in fragmented landscapes. However, the specific contributions of nocturnal frugivores, particularly in above‐ground (arboreal) strata, are often overlooked, leading to ...

Passeriformes: nest predators and prey in a Neotropical Savannah in Central Brazil
Zoologia (Curitiba), 2009 The identification of predators of birds' nests, crucial to a better understanding of predator-prey interactions, remains poorly known. Here we provide evidence that birds, and especially passerines, may depredate birds' nests in the Cerrado (Neotropical

Journal of Animal Ecology, EarlyView.Tracking data from ~10 g songbirds illuminate how weather conditions affect the initiation of long‐distance migratory flights across the Gulf of Mexico during autumn and spring. Seasonal differences and weak migratory connectivity near the Gulf suggest adaptive responses to weather, with future climate trends potentially reducing crossing favorability ...

Habitat imprinting in breeding territory selection of a long‐lived bird of prey
Journal of Animal Ecology, EarlyView.A unique long‐term dataset has allowed this study of an important habitat selection mechanism, habitat imprinting, in a species which is typically extremely challenging to study. It gives us better understanding of the role of early experience in selection of breeding sites in long‐lived species with high breeding site fidelity.
