Seasonal changes in buoyancy and diving behaviour of adult grey seals
(2000-08)
Phocid seals go through dramatic seasonal changes in body mass and composition as a result of
the spatial and temporal separation of foraging, reproduction and moulting. These changes in body
fat content and body mass ...
Costs of locomotion and vertic dynamics of cephalopods and fish
(2000-12)
The world's oceans are three-dimensional habitats that support high diversity and biomass. Because the densities of most of the constituents of life are greater than that of seawater, planktonic and pelagic organisms had ...
Coastal food web structure, carbon storage, and nitrogen retention regulated by consumer pressure and nutrient loading
(2000-03)
By factorial field experiments we analyzed the relative effects of increased nutrient (N+P) loading and natural grazing pressure on species composition, carbon storage, and nitrogen retention in the Baltic Sea littoral ...
Temporal and spatial variability in settlement and recruitment of echinoderms in kelp beds and barrens in Nova Scotia
(2000-10)
Settlement and recruitment of echinoderms were measured in 2 adjacent habitats: a kelp bed
(Laminaria longicruris) and an echinoid (Strongylocentrotus droebachiensis)-dominated barren ground
at each of 2 sites in the ...
The role of development, parental behavior, and nestmate competition in fledging of nestling Tree Swallows
(2000-10)
Fledging (i.e. leaving the nest) in altricial birds is a major step toward independence. The timing of this important event may be influenced by nestling development, parental behavior, and sibling interactions. In this ...
Characteristics of predators and offspring influence nest defense by Arctic and Common Terns
(2000-05)
Nest defense is a critical aspect of parental care that entails both costs and benefits. The purpose of this study was to examine patterns of nest defense in a colony of Arctic and Common Terns (Sterna paradisaea and S, ...
Effect of a low-fat diet on body composition and blubber fatty acids of captive juvenile harp seals (Phoca groenlandica)
(2000-01)
We investigated the effects of a change from a high-fat diet to a low-fat diet of differing
fatty acid (FA) composition on the body composition and blubber FA of five captive juvenile harp
seals. Seals that had been ...
Nucleotide sequence of 5S rDNA and localization of the ribosomal RNA genes to metaphase chromosomes of the Tilapiine cichlid fish, Oreochromis niloticus
(2000-10)
In this study, we report the cloning and nucleotide sequence of PCR-generated 5S rDNA from the Tilapiine cichlid fish, Oreochromis niloticus. Two types of 5S rDNA were detected that differed by insertions and/or deletions ...
