Food regulates the Serengeti wildebeest: a 40‐year record
Summary 1. The migratory wildebeest (Connochaetes taurinus (Burchell)) population of Serengeti has been monitored for 40 years (1958–1998). The population increased from 1963 to 1977, stabilizedExpand

An evaluation of the effects of conservation and fishery enhancement hatcheries on wild populations of salmon.
The historical, political and scientific aspects of salmon hatchery programmes designed to enhance fishery production, or to recover endangered populations, are reviewed. We start by pointing outExpand

Long-term ecosystem dynamics in the Serengeti: lessons for conservation.
Data from long-term ecological studies further understanding of ecosystem dynamics and can guide evidence-based management. In a quasi-natural experiment we examined long-term monitoring data onExpand

Brown bears selectively kill salmon with higher energy content but only in habitats that facilitate choice
Pacific salmon return to spawn in thousands of streams across the Pacific Rim, from large rivers to tiny headwater streams. Once on the spawning grounds, salmon undergo dramatic biochemical changesExpand

Marine and freshwater climatic factors affecting interannual variation in the timing of return migration to fresh water of sockeye salmon (Oncorhynchus nerka)
Interannual variation in the timing of the return migration to fresh water of adult sockeye salmon, Oncorhynchus nerka, from 46 populations throughout the species North American range was examined inExpand

Long-term trends in carnivore abundance using distance sampling in Serengeti National Park, Tanzania
Summary 1. Carnivores can have critical impacts on ecosystems, provide economic value through tourism and are often important flagships. However, their biological traits (e.g. low density, crypticExpand

Evaluating habitat effects on population status: influence of habitat restoration on spring‐run Chinook salmon
SUMMARY 1. A key element of conservation planning is the extremely challenging task of estimating the likely effect of restoration actions on population status. To compare the relative benefits ofExpand

Directional selection by fisheries and the timing of sockeye salmon (Oncorhynchus nerka) migrations.
The timing of migration from feeding to breeding areas is a critical link between the growth and survival of adult animals, their reproduction, and the fitness of their progeny. Commercial fisheriesExpand

Predation by Bears Drives Senescence in Natural Populations of Salmon
Classic evolutionary theory predicts that populations experiencing higher rates of environmentally caused (“extrinsic”) mortality should senesce more rapidly, but this theory usually neglectsExpand

Road will ruin Serengeti
Tanzania's iconic national park must not be divided by a highway, say Andrew Dobson, Markus Borner, Tony Sinclair and 24 others. A route farther south would bring greater benefits to development andExpand
