In this review we detail the impact of climate change on marine productivity, on marine
environmental stochasticity and cyclicity, and on the spatio-temporal match–mismatch of …

In the southern Benguela ecosystem off South Africa, there were recent shifts to the south
and east in the distributions of three forage resources (anchovy, sardine, rock lobster), which …

Worldwide fisheries generate large volumes of fishery waste and it is often assumed that this
additional food is beneficial to populations of marine top-predators. We challenge this …

Summary 1 Remote‐sensing measurements of marine primary productivity are widely used
to predict the distribution and movements of marine top predators, despite the fact that …

Animal-borne sensors enable researchers to remotely track animals, their physiological
state and body movements. Accelerometers, for example, have been used in several studies …

Changes in two contrasting ecosystems of the Benguela upwelling region, one dominated at
mid-trophic level by jellyfishes (Namibia, northern Benguela ecosystem, where small pelagic …

The number of African penguins Spheniscus demersus breeding in South Africa collapsed
from about 56 000 pairs in 2001 to some 21 000 pairs in 2009, a loss of 35 000 pairs (> …

Niche variation is a widespread phenomenon that has important implications for ecological
interactions and conservation biology, but few studies have quantified the trophic niche …

Industrial-scale fisheries are often thought to reduce food availability for top predators. It is
essential to estimate the spatial and temporal overlap over a fine scale between fisheries …

Prey aggregations, such as fish schools, attract numerous predators. This typically leads to
the formation of multispecific groups of predators. These aggregations can be seen both as …
