Systematic monitoring of seabird populations in Canada has been ongoing since the 1920s
and the monitoring of diets and other biological indicators of ecosystem change started in …

We review the effects of fishing on benthic fauna, habitat, diversity, community structure and
trophic interactions in tropical, temperate and polar marine environments and consider …

Evolution has produced a vast array of morphological and physiological adaptations in
seabirds that enable them to exploit the ocean's food resources in myriad ways. As …

Significant depletions of marine fish populations due to overfishing are becoming more and
more common. Such depletions have serious consequences not only for the fished species …

We examined how seabirds might be used to study marine environmental variables, which
necessitates knowing location and the value of the variable to be studied. Five systems can …

Studies of the body condition of five marine vertebrate predators in the Beaufort Sea,
conducted independently during the past 2–4 decades, suggest each has been affected by …

Trends in the composition of nestling thick-billed murre diets were analyzed for the period
1980-2002 on the basis of observations of food delivered to nestlings at two breeding …

Climate change and overfishing are increasingly causing unanticipated changes in marine
ecosystems (eg shifts in species dominance). In order to understand and anticipate these …

Millennial and centurial changes in oceanography influence the distributions and movement
patterns of fish and invertebrates. These changes, in turn, determine the availability of food …

We investigated the roles of food shortage and predation in anticipated breeding failure of
black-legged kittiwakes Rlssa trldactyla at Great Island, Kr~ tless Bay, Newfoundland …
