Diet studies of seabirds: a review and recommendations
TLDR
To enhance comparability of findings among studies, species, and oceanographic regions, a recommendation on standards for the reporting of results in the literature is made.
Activity-specific metabolic rates of free-living northern gannets and other seabirds
TLDR
Statistical analyses of metabolic rates of free—living seab birds indicated that rates are elevated in seabirds in cold—water regions and inSeabirds that use flapping flight, but do not vary with phylogenetic order.
The impacts of fishing on marine birds
Birds are the most conspicuous, wide-ranging, and easily studied organisms in the marine environment. They can be both predators and scavengers, and they can be harmed by and can benefit from fishing
Diets of shags Phalacrocorax aristotelis and cormorants P. carbo in Norway and possible implications for gadoid stock recruitment
TLDR
Signs were thatPredation by shags and cormorants could be a factor limiting the recruitment of cod and saithe into what are now severely reduced, but commercially important stocks in the Norwegian and Barents Seas.
Population genetic structure and the effect of founder events on the genetic variability of moose, Alces alces, in Canada
TLDR
Comparisons of allele frequencies for moose from 11 regions of the country suggested that there are at least seven genetically distinct populations in North America, namely Alberta, eastern Ontario, New Brunswick, Cape Breton, Labrador, western Newfoundland, and the Avalon Peninsula of Newfoundland.
Birds as indicators of change in marine prey stocks
For millenia humans have followed birds at sea to locate fish and mammals. Seabirds are highly visible wide-ranging upper trophic level consumers that can indicate marine productivity and biotic
Seabirds at risk around offshore oil platforms in the north-west Atlantic.
TLDR
It is essential to implement comprehensive, independent arm's length monitoring of potential avian impacts of offshore hydrocarbon platforms in the North-west Atlantic, which should include quantifying and determining the nature, timing and extent of bird mortality caused by these structures.
Pursuit plunging by northern gannets (Sula bassana) "feeding on capelin (Mallotus villosus)"
TLDR
It is concluded that extended, deep dives were directed at deep schools of capelin, a small pelagic fish, and it is hypothesized that V–shaped dives were aimed at larger, pelagic fishes and squids.
Diet and trophic position of Leach's storm-petrel Oceanodroma leucorhoa during breeding and moult, inferred from stable isotope analysis of feathers
TLDR
Combining conventional dietary sampling with stable isotope analysis of nitrogen and carbon in feathers of Leach’s storm-petrels Oceanodroma leucorhoa provided some of the first insights into the year-round ecology of the smallest and most abundant seabird breeding in eastern North America.
