Inter- and intra-annual differences in foraging ecology of the chick-rearing Brünnich’s guillemots (Uria lomvia) breeding in the High Arctic [PDF]

open access: yesRoyal Society Open Science
The foraging ecology of seabirds depends on both external and internal factors. Seabirds can modify their feeding strategy depending on current food availability to maintain optimal energy levels provisioned to the offspring. Here, we investigated inter-

Foraging ecology drives social information reliance in an avian eavesdropping community [PDF]

open access: yesEcology and Evolution, 2019
Vertebrates obtain social information about predation risk by eavesdropping on the alarm calls of sympatric species. In the Holarctic, birds in the family Paridae function as sentinel species; however, factors shaping eavesdroppers' reliance on their ...

Sex differences in foraging ecology of the chick rearing Brünnich’s Guillemots (Uria lomvia) breeding in a High Arctic colony [PDF]

open access: yesScientific Reports
Some seabirds, such as alcids exhibit sexual monomorphism, often displaying intersexual variation in parental investment and breeding ecology. In the Brünnich’s Guillemot (Uria lomvia), both sexes contribute to incubation and chick rearing.

The foraging behaviour of hummingbirds through space and time [PDF]

open access: yes, 2015
Central place foragers, such as territorial hummingbirds, feed from resources that tend to be constant in space and to replenish with time (e.g. nectar in flowers).

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 dives of sperm whales in the north-western Mediterranean Sea [PDF]

open access: yes, 2012
Oceanic odontocetes rely on echolocation to forage on pelagic or benthic prey, but their feeding ecology is difficult to study. We studied sperm whale foraging dives during summer in the north-western Mediterranean, using visual and passive acoustic ...
