Foraging ecology of the African Penguin Spheniscus demersus in relation to ocean physical processes. [PDF]

open access: yes, 2012
Includes abstract.This research demonstrated the dual utility of bio-loggers as a method for generating accurate, high-resolution oceanographic data. These data can be used in future studies, generating a cross disciplinary platform for research.

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 ...

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.

Comparative foraging ecology of two broad-ranging migrants, grey plover Pluvialis Squatarola and whimbrel Numenius Phaeopus (Aves: Charadrii), in tropical and temperate latitudes of the Western Indian Ocean [PDF]

open access: yes, 1994
Bibliography: leaves 186-205.A seasonal study of the nonbreeding foraging ecology of Grey Plovers and Whimbrels was undertaken at the Zwartkops estuary, South Africa, and additional data were collected from a variety of sites in tropical and south ...

Experimental studies of social foraging in budgerigars, Melopsittacus undulatus [PDF]

open access: yes, 2015
Many animals are social foragers. Foraging with others may confer a number of advantages, but is also likely to present a number of challenges that are not encountered by solitary foragers.

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,

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 ...

Roosting and foraging social structure of the endangered Indiana bat (Myotis sodalis). [PDF]

open access: yesPLoS ONE, 2014
Social dynamics are an important but poorly understood aspect of bat ecology. Herein we use a combination of graph theoretic and spatial approaches to describe the roost and social network characteristics and foraging associations of an Indiana bat ...
