There exists little doubt that the Earth's biodiversity is declining. The Nature Conservancy, for
example, has documented that one-third of the plant and animal species in the United States …

We focus on the implications of movement, landscape variables, and spatial heterogeneity
for food web dynamics. Movements of nutrients, detritus, prey, and consumers among …

Linking environmental sustainability with poverty reduction and social justice, and making
science and technology work for the poor, have become central practical, political and moral …

Fundamentals of Soil Ecology, 3rd Edition, offers a holistic approach to soil biology and
ecosystem function, providing students and ecosystem researchers with a greater …

Individual-based models are an exciting and widely used new tool for ecology. These
computational models allow scientists to explore the mechanisms through which population …

Food webs in nature have multiple, reticulate connections between a diversity of consumers
and resources. Such complexity affects web dynamics: it first spreads the direct effects of …

Interactions between biotic and abiotic processes complicate the design and interpretation
of ecological experiments. Separating causality from simple correlation requires …

Traditional approaches to the study of food webs emphasize the transfer of local primary
productivity in the form of living plant organic matter across trophic levels. However, dead …

Our capacity to predict trajectories of ecosystem degradation and recovery is limited,
especially when impairments are caused by multiple stressors. Recovery may be fast or …

▪ Abstract Animals are important in nutrient cycling in freshwater ecosystems. Via excretory
processes, animals can supply nutrients (nitrogen and phosphorus) at rates comparable to …
