Tendencias poblacionales y reproductivas (1985-2025) del buitre leonado Gyps fulvus en Bizkaia [PDF]

Munibe Ciencias Naturales
El 87% de las especies de buitres del mundo están en algún grado de amenaza, motivado fundamentalmente por el incremento de la mortalidad no natural, cambios en el uso del suelo y regulaciones de las actividades agro-ganaderas.

How Management Practices Shape the “Local Habitat Signature” That Modulates Bird Communities in Urban Green Spaces

Biotropica, Volume 58, Issue 1, January 2026.
Local scale factors, not just the broad urban gradient, are the key drivers of urban bird communities. Our multi‐scale study found that specific management practices, such as managing leaf litter depth or the presence of unmanaged tall grass, explained the largest portion of variation in bird composition.

The birds and the trees: Avian ecosystem (dis)service perspectives and farmers' willingness to plant native trees in the agricultural landscape of the Galapagos Islands

People and Nature, Volume 7, Issue 12, Page 3182-3206, December 2025.
Abstract Agricultural landscapes hold great potential for biodiversity conservation; however, this will require finding solutions that work for both people and nature. Increasingly, the conservation community is calling for more cross‐disciplinary research integrating ecological questions with social and behavioural sciences for a more complete and ...

Application of photographic ‘capture–recapture' modelling to estimate recruitment and apparent survival in a long‐lived territorial raptor

Journal of Avian Biology, Volume 2025, Issue 6, November 2025.
Survival is a life history trait that contributes most to population dynamics in long‐lived birds, and the study of individual characteristics is relevant for population conservation. Here we provide information on territorial recruitment and individual replacement in a population of Bonelli's eagle Aquila fasciata in southeastern Spain based on a long‐

The Link Between Range Size, Niche Specialisation and Diversification in One of the Most Successful Avian Radiations, the New World Flycatchers (Tyrannoidea)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Range size constitutes a fundamental characteristic of every species and is commonly believed to influence diversification rates. This relationship is potentially dependent on the mode of speciation and other intrinsic factors, including geographic setting and species attributes. Yet, not only the size of the geographic range, but also the

Assessing the Corn Belt as an anthropogenic barrier to migrating landbirds in the United States

Conservation Biology, Volume 39, Issue 5, October 2025.
Abstract Migrating landbirds adjust their flight and stopover behaviors to efficiently cross inhospitable geographies, such as the Gulf of Mexico and the Sahara Desert. In addition to these natural barriers, birds may increasingly encounter anthropogenic barriers created by large‐scale changes in land use. One such barrier could be the Corn Belt in the
