The predictability of the physical arrangement of plants, at whatever scale it is viewed, is referred to as a spatial pattern. Spatial pattern is a crucial aspect of vegetation that has important implications not only for the plants themselves, but also for other organisms that interact with plants, such as herbivores and pollinators; or those animals for which plants provide a habitat. This book describes and evaluates methods for detecting and quantifying a variety of characteristics of spatial pattern. As well as discussing the concepts on which these techniques are based, the book...

Predicting how terrestrial ecosystems might respond in the future to large-scale human-generated changes is a major challenge for ecologists. In Terrestrial Ecosystems in Changing Environments, Herman H. Shugart describes the fundamental ecological concepts, theoretical developments, and quantitative analyses involved in understanding the responses of natural systems to change. The key ecological concepts described include the ecosystem paradigm, niche theory, vegetation/climate relationships, landscape ecology and ecological modeling. A variety of ecological models are presented, and their...

Riparian Landscapes examines the ecological systems of streamside and floodplain areas from the perspective of landscape ecology. The author describes the specific spatial pattern of riparian vegetation as a result of, and a control on, the ecological, geomorphological, and hydrological processes that operate along rivers. He also discusses the role of the riparian zone in controlling species distribution and abundance and highlights the intelligent management of these valuable ecological resources. Finally, Malanson explores the potential for linking hydrological, geomorphological and...

In this book, a multidisciplinary research team tests this idea by manipulating whole lakes experimentally, and coordinating this with paleolimnological studies, simulation modeling, and small-scale enclosure experiments. Contributors describe consequences of predator-prey interactions, behavioral responses of fishes, diel vertical migration of zooplankton, plankton community change, primary production, nutrient cycling and microbial processes. Paleolimnological techniques enable the reconstruction of trophic interactions from past decades. Prospects for analyzing the interaction of food web...

Considers different aspects of man's intervention with natural vegetation and the landscape resulting from a long equilibrium of co-existence.

Lee Frelich provides a major contribution to the study of temperate-zone forest dynamics by considering three important themes: the combined influence of wind, fire, and herbivory on the successional trajectories and structural characteristics of forests; the interaction of deciduous and evergreen tree species to form mosiacs; and the significance of temporal and spatial scale with regard to the overall impact of disturbances. These themes are explored via case studies from the forests in the Lake States of Minnesota, Wisconsin and Michigan, where the presence of large primary forest remnants...

The adaptation of herbivore behavior to seasonal and locational variations in vegetation quantity and quality is inadequately modelled by conventional methods. Norman Owen-Smith innovatively links the principles of adaptive behavior to their consequences for population dynamics and community ecology, through the application of a metaphysiological modeling approach. The main focus is on large mammalian herbivores occupying seasonally variable environments such as those characterized by African savannas, but applications to temperate zone ungulates are also included. Issues of habitat...

Birks and Birks (both palaeoecology, U. of Bergen and U. College London) introduce undergraduate and research students with such backgrounds as botany, zoology, geology, geography, and archaeology, to the science of reconstructing the biota, communities, and environments during the period that saw the first appearance and early development of human

The theme of this book is the invasion of land by animal lines which originated in aquatic environments. It brings together physiological and ecological evidence to show both the likely routes taken out of the sea by the aquatic ancestors of terrestrial animals and the changes in structure and function associated with these routes. The author takes an ecophysiological approach, and by using representative examples, provides a novel background against which both the terrestrial adaptations of individual species and the make up and function of terrestrial ecosystems can be considered. Dr Little...
