Surface pauses in relation to dive duration in imperial cormorants; how much time for a breather?
(Company of Biologists, 2004)
Air-breathing animals diving to forage can optimize time underwater by diving with just enough oxygen for the projected performance underwater. By so doing they surface with minimal body oxygen levels, which leads to maximal ...
Diving patterns in the Antarctic Shag
(Waterbird Society, 2004-12)
The diving patterns of the Antarctic Shag ( Phalacrocorax bransfieldensis ) were studied by direct observation on individuals foraging at Harmony Cove, Nelson Island, South Shetland Islands, during the 1995/96 and 1996/97 ...
Persistence in diving American mink
(Springer, 2015-08)
Background: American mink forage on land and in water, with aquatic prey often constituting a large proportion of their diet. Their long, thin body shape and relatively poor insulation make them vulnerable to heat loss, ...
Flexible foraging for finding fish: variable diving patterns in Magellanic penguins Spheniscus magellanicus from different colonies
(Wiley Blackwell Publishing, Inc, 2014-04-16)
Seabirds have to deal with environmental variability and are predicted to modulate foraging behavior to maximize fitness, with particularly strong selection pressure for optimal behavior during chick provisioning when ...
Options for modulating intra-specific competition in colonial pinnipeds: the case of harbour seals (Phoca vitulina) in the Wadden Sea
(PeerJ, 2015-06)
Colonial pinnipeds may be subject to substantial consumptive competition because they are large, slow-moving central place foragers. We examined possible mechanisms for reducing this competition by examining the diving ...
Diving classification and behavior of free-ranging female southern elephant seals based on threedimensional movements and video-recorded observations
(Inter-Research, 2019-06-18)
The goal of this study was to classify dives of free-ranging female southern elephant seals Mirounga leonina from Península Valdés, Argentina, during their 2 mo post-breeding migration. Classifications were based on ...
Dive depth and plumage air in wettable birds: the extraordinary case of the imperial cormorant
(Inter-Research, 2007-12)
Cormorants are considered to be remarkably efficient divers and hunters. In part, this is due to their wettable plumage with little associated air, which allows them to dive with fewer energetic costs associated with ...
Diving patterns of breeding female rockhopper penguins (Eudyptes chrysocome): Noir Island, Chile
(Springer, 2009-12)
The diving behaviour of female southern rockhopper penguins (Eudyptes chrysocome) was studied at Noir Island (54°30′S-73°00′W), Chile, in the southeast Pacific Ocean. This isolated island is located at the edge of the ...
Dive performance in a small-bodied, semi-aquatic mammal in the wild
(Alliance Communications Group Division Allen Press, 2012-02)
Aquatic foraging is a fundamental component of the behavior of a number of small mammals, yet comprehensive observations of diving are often difficult to obtain under natural circumstances. Semiaquatic mammals, having ...
Exceptional foraging plasticity in King Penguins (Aptenodytes patagonicus) from a recently established breeding site in Tierra del Fuego, Chile
(Elsevier B.V., 2021)
© 2021 The AuthorsAnimals constantly test the borders of their own ecological niche and tend to expand their range, which is now additionally challenged by global climate change. Following human exploitation throughout the ...
