Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Classifying avian drinking behaviour: ecological insights and implications in a changing world

open access: yesBiological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...
