The world's eastern boundary upwelling systems (EBUSs) contribute disproportionately to
global ocean productivity and provide critical ecosystem services to human society. The …

All ecosystems are exposed to gradual changes in climate, nutrient loading, habitat
fragmentation or biotic exploitation. Nature is usually assumed to respond to gradual change …

We investigated microplastics in the digestive tracts of 64 Japanese anchovy (Engraulis
japonicus) sampled in Tokyo Bay. Plastic was detected in 49 out of 64 fish (77%), with 2.3 …

Climate change and resource exploitation have been shown to modify the importance of
bottom-up and top-down forces in ecosystems. However, the resulting pattern of trophic …

Determining the form of key predator-prey relationships is critical for understanding marine
ecosystem dynamics. Using a comprehensive global database, we quantified the effect of …

Aquaculture's pressure on forage fisheries remains hotly contested. This article reviews
trends in fishmeal and fish oil use in industrial aquafeeds, showing reduced inclusion rates …

Forage fish play a pivotal role in marine ecosystems and economies worldwide by
sustaining many predators and fisheries directly and indirectly. We estimate global forage …

Low–trophic level species account for more than 30% of global fisheries production and
contribute substantially to global food security. We used a range of ecosystem models to …

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 …

Quantitative modeling methods have become a central tool in the management of harvested
fish populations. This book examines how these modeling methods work, why they …
