Recent studies document unprecedented declines in marine top predators that can initiate
trophic cascades. Predicting the wider ecological consequences of these declines requires …

Summary 1 Top‐down control can be an important determinant of ecosystem structure and
function, but in oceanic ecosystems, where cascading effects of predator depletions …

Ecological understanding of the role of consumer–resource interactions in natural food webs
is limited by the difficulty of accurately and efficiently determining the complex variety of food …

" More information is always better, and full information is best. More computation is always
better, and optimization is best." More-is-better ideals such as these have long shaped our …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

The vast scope of conservation problems has forced biologists and managers to rely on"
surrogate" species to serve as shortcuts to guide their decision making. These species …

Stable isotope analysis (SIA) has emerged as a common tool in ecology and has proven
especially useful in the study of animal diet, habitat use, movement, and physiology. SIA has …

It would not have been possible for me to write the three editions of this book without a
double dose of extraordinary fortune: to have been part of the Woods Hole scientific …

Niche partitioning of time, space or resources is considered the key to allowing the
coexistence of competitor species, and particularly guilds of predators. However, the extent …

We review seven Arctic and four subarctic marine mammal species, their habitat
requirements, and evidence for biological and demographic responses to climate change …
