Correlated evolution of wing morphology and echolocation calls in bats

open access: yesFrontiers in Ecology and Evolution, 2022
IntroductionFlight and echolocation are two crucial behaviors associated with niche expansion in bats. Previous researches have attempted to explain the interspecific divergence in flight morphology and echolocation vocalizations in some bat groups from ...

Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]

open access: yes, 2017
Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...

The Effect of nest Size and Species Identity on Plant Selection in Acromyrmex Leaf-Cutting Ants

open access: yesSociobiology, 2018
Leaf-cutting ants are key organisms because their role as primary consumers and potential agricultural pests. However, their foraging ecology was mostly studied as response of extrinsic factors such as climate and plant species traits.

Foraging mode affects extinction risk of snakes and lizards, but in different ways

open access: yesConservation Letters, 2023
What factors render a species more vulnerable to extinction? In reptiles, foraging mode is a fundamental ecological dimension: some species actively search for immobile prey, whereas others ambush mobile prey. Foraging mode is linked to diet, morphology,

Identifying Space Use at Foraging Arena Scale within the Home Ranges of Large Herbivores.

open access: yesPLoS ONE, 2015
An intermediate spatiotemporal scale of food procurement by large herbivores is evident within annual or seasonal home ranges. It takes the form of settlement periods spanning several days or weeks during which foraging activity is confined to spatially ...

Influence of spatial and temporal dynamics of agricultural practices on the lesser kestrel [PDF]

open access: yes, 2011
1. European agriculture is facing dramatic changes that are likely to have marked impacts on farmland biodiversity. There is an urgent need to develop land management strategies compatible with the conservation of biodiversity.2.

Multidimensional nutritional ecology and urban birds

open access: yesEcosphere, 2018
There is growing interest in the question of how urbanization affects the ecology of birds, across timescales from relatively short‐term physiological responses to long‐term evolutionary adaptation.

Fine-scale foraging ecology of leatherback turtles

open access: yesFrontiers in Ecology and Evolution, 2015
Remote tracking of migratory species and statistical modeling of behaviors have enabled identification of areas that are of high ecological value to these widely distributed taxa.
