Trophic Downgrading of Planet Earth
This empirical work supports long-standing theory about the role of top-down forcing in ecosystems but also highlights the unanticipated impacts of trophic cascades on processes as diverse as the dynamics of disease, wildfire, carbon sequestration, invasive species, and biogeochemical cycles.

Serengeti II : dynamics, management, and conservation of an ecosystem
The aim of this text is to provide an up-to-date understanding of the Serengeti-Mara ecosystem in East Africa, home to one of the largest and most diverse populations of animals in the world.
Effect of habitat area and isolation on fragmented animal populations
The results indicate that patch area and isolation are indeed important factors affecting the occupancy of many species, but properties of the intervening matrix should not be ignored and improving matrix quality may lead to higher conservation returns.
Impact of Food and Predation on the Snowshoe Hare Cycle
Food and predation together had a more than additive effect, which suggests that a three-trophic-level interaction generates hare cycles.
Bushmeat Hunting, Wildlife Declines, and Fish Supply in West Africa
It is shown that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in biomass of 41 wildlife species, highlighting the urgent need to develop cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions of tropical wildlife.
Planning for success: Serengeti lions seek prey accessibility rather than abundance
Summary 1. We used long-term radio-telemetry data to investigate how Serengeti lions ( Panthera leo ) distribute themselves with respect to hunting opportunities. Specifically, we investigate whether
Food regulates the Serengeti wildebeest: a 40‐year record
Rainfall in the dry season was the most important extrinsic determinant of food supply for the wildebeest population but food was related to mortality only when population density was incorporated.
