Background The spatiotemporal distribution of resources is a critical component of realized
animal distributions. In agricultural landscapes, space use by generalist consumers is …

Eurasian otters are apex predators of freshwater ecosystems and a recovering species
across much of their European range; investigating the dietary variation of this predator over …

The study of predator–prey interactions is commonly analyzed using functional responses to
gain an understanding of predation patterns and the impact they have on prey populations …

The regional climatic context in which Chalcolithic (MIR5) and Bronze Age (MIR4) levels
from El Mirador cave (Sierra de Atapuerca, Burgos, Spain) are framed is affected by the 4.2 …

Top predators shape the communities of sympatric predators by killing and displacing
smaller predators. Predation risk pushes smaller predators to select enemy-free spaces …

Lethal interactions can shape ecosystem structure, and consequently understanding their
causes is ecologically relevant. To improve both empirical and theoretical knowledge on …

Para determinar el espectro trófico del Halconcito Colorado (Falco sparverius) en América
del Sur y en Ecuador se elaboró un listado con los datos de las especies vertebradas en su …

According to optimal foraging theory, a predator should select the most beneficial prey in
terms of energy gain relative to handling time. For the pine marten (Martes martes), rodents …

Optimal foraging theory predicts that in situations of high prey abundance, predators will
select the largest ones if the cost of capture is similar. This relationship is not clear in species …

Food spectrum was based on 62,314 prey specimens belonging to 367 taxa collected
between 1994 and 2013. The diet included 40.9% new taxa for the Eagle owl food in …
