Summary 1 A fundamental goal of ecological network research is to understand how the
complexity observed in nature can persist and how this affects ecosystem functioning. This is …

Community assembly provides a conceptual foundation for understanding the processes
that determine which and how many species live in a particular locality. Evidence suggests …

How do we explain the remarkably abrupt changes that sometimes occur in nature and
society--and can we predict why and when they happen? This book offers a comprehensive …

Why do species live where they live? What determines the abundance and diversity of
species in a given area? What role do species play in the functioning of entire ecosystems …

Trophic cascades—the top-down regulation of ecosystems by predators—are an essential
aspect of ecosystem function and well-being. Trophic cascades are often drastically …

Contaminants such as petroleum hydrocarbons, heavy metals and pesticides can cause
direct toxic effects when released into aquatic environments. Sensitive species may be …

This review discusses the interface between two of the most important types of interactions
between species, interspecific competition and predation. Predation has been claimed to …

▪ Abstract Many terrestrial communities include omnivorous arthropods that feed on both
prey and plant resources. In this review we first discuss some unique morphological …

A large number of studies have presented empirical arguments for the existence of
alternative stable states (ASS) in a wide range of ecological systems. However, most of …

Intraguild predation (IGP), defined as killing and eating among potential competitors, seems
to be a ubiquitous interaction, differing from competition or predation. In the present study we …
