The Status of the World's Land and Marine Mammals: Diversity, Threat, and Knowledge
TLDR
A comprehensive assessment of the conservation status and distribution of the world's mammals is presented, compiled by 1700+ experts, to suggest common mechanisms driving diversity and endemism across systems. Expand
FEEDING RATES OF SEALS AND WHALES
SUMMARY (1) The hypothesis that rates of food consumption by marine mammals are similar to those of terrestrial mammals was tested by comparing rates of food consumption of nongrowing and growing,… Expand
The Impact of Conservation on the Status of the World’s Vertebrates
TLDR
Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups. Expand
The marine ecosystem of Kongsfjorden, Svalbard
Kongsfjorden is a glacial fjord in the Arctic (Svalbard) that is influenced by both Atlantic and Arctic water masses and harbours a mixture of boreal and Arctic flora and fauna. Inputs from large… Expand
Marine mammals and the community structure of the Estuary and Gulf of St Lawrence, Canada: evidence from stable isotope analysis
TLDR
A multiple stable isotope and multiple tissue approach suggested that marine mammals occupied the highest trophic positions in the food webs of both communities and that they overlapped with one another to some extent trophically. Expand
Assessing species' vulnerability to climate change
The effects of climate change on biodiversity are increasingly well documented, and many methods have been developed to assess species' vulnerability to climatic changes, both ongoing and projected… Expand
Allometry of diving capacity in air-breathing vertebrates
TLDR
The diving capacities of penguins had the highest correlations with body mass, and many of the smaller taxonomic groups also had a strong allometric relationship between diving capacity (maximum depth and duration) and body mass. Expand
A simple new algorithm to filter marine mammal Argos locations
During recent decades satellite telemetry using the Argos system has been used extensively to track many species of marine mammals. However, the aquatic behavior of most of these species results in a… Expand
Functional classification of harbor seal (Phoca vitulina) dives using depth profiles, swimming velocity, and an index of foraging success
TLDR
Time-depth-speed recorders and stomach-temperature sensors were deployed on harbor seals in the St. Lawrence estuary to examine their diving and foraging behavior, finding feeding occurred during dives of all five types, four of which were U-shaped, while one was V-shaped. Expand
The broad footprint of climate change from genes to biomes to people
TLDR
The full range and scale of climate change effects on global biodiversity that have been observed in natural systems are described, and a set of core ecological processes that underpin ecosystem functioning and support services to people are identified. Expand
