For over sixty years, understanding the causes of multiannual cycles in animal populations has been a central issue in ecology. This book brings together ten of the leaders in this field to examine the major hypotheses and recent evidence in the field, and to establish that trophic interactions are an important factor in driving at least some of the major regular oscillations in animal populations that have long puzzled ecologists.

Until comparatively recently, the remoteness, inaccessibility, and extreme climate have meant that the vast pack-ice zone around the Antarctic continent was one of the least-known marine ecosystems on Earth. Myths and speculations prevailed in the literature, often derived from an anthropocentric way of thinking that considered the sea-ice environment as predominantly hostile to marine life. This picture has changed drastically now as a result of a series of international efforts, the most recent of which has been the highly successful EASIZ (Ecology of the Antarctic Sea Ice Zone) programme of the Scientific Council on Antarctic Research (SCAR). Focusing, in contrast to other international programmes, on life at the seafloor, EASIZ has attempted to link processes in the three major marine subsystems (sea ice, pelagic and benthic) within the pack-ice zone. Work has been carried out from both research ships and shore-based research stations. This work included organisms ranging in size from bacteria to seals and covered topics as diverse as biodiversity, iceberg scour, pelagobenthic coupling, autecology, and ecophysiology. Consequently, we now view the sea-ice zone as a rich system with highly adapted organisms, considerable natural disturbance from ice, low resilience and of great potential importance as an indicator for climate change.

The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.
