Behavioural co‐option of plant secondary compounds by a cavity‐nesting bird is an adaptation against competition and predation

Functional Ecology, Volume 39, Issue 2, Page 362-370, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions with competitors and predators can generate strong selection and favour the evolution of novel strategies for mitigating fitness costs. Adaptations to mitigate competition and predation risk often involve evolution of traits which directly reduce costs ...

Associations between a feral equid and the Sonoran Desert ecosystem Asociaciones Entre un Equino Salvaje y el Ecosistema del Desierto Sonorense

Wildlife Monographs, Volume 215, Issue 1, July 2024.
We documented negative associations between feral burros and several elements of the Sonoran Desert ecosystem, and suggest that differences associated with this feral equid may be ecologically important and may have the potential to affect the long‐term viability of this ecosystem.

Rol de la cronología de anidación y las características parentales en el éxito reproductivo del piquero de Nazca (Sula granti) en Isla de la Plata, Ecuador [PDF]

, 2017
Reproductive success in Sula granti could be influenced by nesting initiation timing, body condition and sexual size dimorphism (SSD). The objective of this investigation is to establish if in S. granti reproductive success is related with nesting timing,

Nest‐site selection and reproductive success of a critically endangered parrot, the Great Green Macaw (Ara ambiguus), in an anthropogenic landscape

Ibis, Volume 166, Issue 2, Page 518-533, April 2024.
Nest‐site selection is the principal way in which secondary cavity‐nesting species mitigate the negative effects of factors such as predation, parasitism and exposure on reproductive success. Large‐bodied secondary cavity‐nesting birds rely on large cavities in mature trees that are often absent or reduced in anthropogenically disturbed forests. Hence,

Sensitivity of North American grassland birds to weather and climate variability

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract Grassland birds in North America have declined sharply over the last 60 years, driven by the widespread loss and degradation of grassland habitats. Climate change is occurring more rapidly in grasslands relative to some other ecosystems, and exposure to extreme and novel climate conditions may affect grassland bird ecology and demographics. To
