Ectoparasites exposure affects early growth and mouth colour in nestlings of a cavity-nesting raptor
AbstractNest-dwelling ectoparasites are a major source of stress for growing nestling birds, as they can negatively impact on growth and physiology,...

Early stages of home range settlement in a newly reintroduced raptor on an island: Bonelli’s eagle (Aquila fasciata) on Mallorca, Spain
Bonelli’s eagle ( Aquila fasciata ) had become extirpated in parts of their Mediterranean distribution, such as on Mallorca Island (Balearic Islands,...

Brood sex ratio modulates the effects of extra food on parental effort and sibling competition in a sexually dimorphic raptor
AbstractConflicts are inherent to family systems and may occur at three levels. First, each parent benefits if its mate takes the greater share of...

Raptors of a Neotropical city: diversity and habitat relationships along an urbanization gradient
Urbanization involves changes in landscape terrain, hydrology, and vegetation. These changes allow some wildlife species to thrive in cities while...

Tolerance and avoidance of urban cover in a southern California suburban raptor community over five decades
We explored nest site placement and re-use relative to ornamental tree usage and urbanization level in a diurnal raptor community in southern...

A tiny, long-legged raptor from the early Oligocene of Poland may be the earliest bird-eating diurnal bird of prey
We report a small hawk-like diurnal bird from the early Oligocene (30–31 million years ago) of Poland. Aviraptor longicrus , n. gen. et sp. is of a...

Variations in defensiveness of a nesting raptor based on the number of human observers near the nest
Swoo** is a defensive behavior used against potential nest predators. Here, we tested the hypothesis that swoo** intensity in a pair of Brown...

The visual fields of the Harpy Eagle (Harpia harpyja)
We describe for the first time the visual fields of the largest tropical raptor, the Harpy Eagle ( Harpia harpyja ), a powerful keystone species that...

Diversity of raptors and nest sites characteristics in an urban area in Southern Chile
Urban areas form a complex, heterogeneous, fragmented mosaic of habitats, including ecosystems in different degrees of alteration. Nevertheless, some...

p300 nucleocytoplasmic shuttling underlies mTORC1 hyperactivation in Hutchinson–Gilford progeria syndrome
The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of cell growth, metabolism and autophagy. Multiple pathways modulate...

Diversity of diurnal raptors in a suburban area of a city in southern Chile
Raptor conservation programs should be based on knowledge of the birds’ ecology in both natural and urban habitats, justifying the inclusion of...

African savanna raptors show evidence of widespread population collapse and a growing dependence on protected areas
The conversion of natural habitats to farmland is a major cause of biodiversity loss and poses the greatest extinction risk to birds worldwide....

A key gene for the climatic adaptation of Apis cerana populations in China according to selective sweep analysis
BackgroundApis cerana is widely distributed in China and, prior to the introduction of western honeybees, was the only bee species kept in China....

Raptor genomes reveal evolutionary signatures of predatory and nocturnal lifestyles
BackgroundBirds of prey (raptors) are dominant apex predators in terrestrial communities, with hawks (Accipitriformes) and falcons (Falconiformes)...

Evidence of non-random mating in a colour polymorphic raptor, the Booted Eagle
Sexual selection and non-random mating are considered, among others, determinant mechanisms for the maintenance of genetic colour polymorphism in...

Impact of predator model presentation paradigms on titi monkey alarm sequences
AbstractPredator presentation experiments are widely used to investigate animal alarm vocalizations. They usually involve presentations of predator...

Inter-individual differences in foraging tactics of a colonial raptor: consistency, weather effects, and fitness correlates
BackgroundConsistent inter-individual differences in behavioural phenotypes may entail differences in energy efficiency and expenditure, with...

Black-and-white pelage as visually protective coloration in colobus monkeys
AbstractConspicuous coloration is often seen as the evolutionary consequence of either sexual selection or warning predators visually about prey...

Juvenile vervet monkeys rely on others when responding to danger
Primate alarm calls are mainly hardwired but individuals need to adapt their calling behaviours according to the situation. Such learning...

Iron drives anabolic metabolism through active histone demethylation and mTORC1
All eukaryotic cells require a minimal iron threshold to sustain anabolic metabolism. However, the mechanisms by which cells sense iron to regulate...
