Development of Microsatellite Markers for Ex Situ Management of the Harpy Eagle Using Next Generation Sequencing

Zoo Biology, EarlyView.
ABSTRACT The Harpy Eagle (Harpia harpyja), one of the largest birds of prey in the world, is threatened with extinction throughout its entire area of occurrence in the Neotropics. While conservation efforts for the wild populations are crucial, it is also important to focus on ex situ conservation actions.

Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

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.

Preservation of stable isotope niche dynamics in squamate museum specimens

Journal of Animal Ecology, EarlyView.
This paper presents the first research on the effects of fluid specimen preservation in a community context, demonstrating the recovery of metrics of niche dynamics across a diverse array of squamate taxa. Abstract Natural history museums are invaluable resources for large‐scale ecological and evolutionary studies, but certain ecological traits can be ...
