Book Description
Rising temperatures are affecting organisms in all of Earth's biomes, but the complexity of ecological responses to climate change has hampered the development of a conceptually unified treatment of them. In a remarkably comprehensive synthesis, this book presents past, ongoing, and future ecological responses to climate change in the context of two simplifying hypotheses, facilitation and interference, arguing that biotic interactions may be the primary driver of ecological responses to climate change across all levels of biological organization. Eric Post's synthesis and analyses of ecological consequences of climate change extend from the Late Pleistocene to the present, and through the next century of projected warming. His investigation is grounded in classic themes of enduring interest in ecology, but developed around novel conceptual and mathematical models of observed and predicted dynamics. Using stability theory as a recurring theme, Post argues that the magnitude of climatic variability may be just as important as the magnitude and direction of change in determining whether populations, communities, and species persist. He urges a more refined consideration of species interactions, emphasizing important distinctions between lateral and vertical interactions and their disparate roles in shaping responses of populations, communities, and ecosystems to climate change.

Book Description
Aboveground-Belowground Linkages provides the most up-to-date and comprehensive synthesis of recent advances in our understanding of the roles that interactions between aboveground and belowground communities play in regulating the structure and function of terrestrial ecosystems, and their responses to global change. It charts the historical development of this field of ecology and evaluates what can be learned from the recent proliferation of studies on the ecological and biogeochemical significance of aboveground-belowground linkages. The book is structured around four key topics: biotic interactions in the soil; plant community effects; the role of aboveground consumers; and the influence of species gains and losses. A concluding chapter draws together this information and identifies a number of cross-cutting themes, including consideration of aboveground-belowground feedbacks that occur at different spatial and temporal scales, the consequences of these feedbacks for ecosystem processes, and how aboveground-belowground interactions link to human-induced global change.

Book Description
It is not possible to understand the apparent stability of the Earth's climate and environment unless we can fully understand how the best possible environmental conditions may be maintained for life to exist. Human colonization of areas with natural biota, for industrial or agricultural activities, will lead to degradation of those natural communities and violation of the BRE (biotic regulation of the environment) principle. Thus to maintain an environment on Earth that is suitable for life it is necessary to preserve and allow the natural recovery of natural biotic communities, both in the oceans and on land. This book is devoted to a quantitative version of the BRE concept, and is built on a foundation of modern scientific knowledge accumulated in the fields of physics and biology.

Book Description
Ever since the concept of the "struggle for life" became the heart of Darwin's theory of evolution, biologists have studied the relevance of interactions for the natural history and evolution of organisms. Although positive interactions among plants have traditionally received little attention, there is now a growing body of evidence showing the ef

Book Description
Variation in environmental conditions is a pervasive feature of natural systems that has profound consequences for the structure of ecological communities. As a result of altered local conditions produced by human urbanisation, shifts in marine habitats from kelp forests to mats of turfing algae are increasingly common. Forecasting whether such ecological change will be accelerated or reversed as a function of modified global conditions is a new form of ecological enquiry. Throughout this thesis, I assessed the conceptual model that while cross-scale abiotic stressors can combine to have interactive effects, management of local conditions can counter-balance this change. My experimental manipulations were intended to test the hypotheses that; 1) cross-scale factors (i.e. local and global) will have interactive effects that increase the probability of expansion of turfs but not kelp, and, 2) management of local conditions (e.g. presence of biota, nutrient enrichment) will dampen the effects of global change on turfs (e.g. forecasted CO2). Change in ecological communities is anticipated where altered environmental conditions have contrasting effects on interacting taxa that determine their composition and relative abundances. Experimental enrichment of CO2 and nutrients influenced biomass accumulation of turf and kelp differently, with turf responding positively to enrichment of both resources while kelp responded to enrichment of nutrients but not CO2. These responses likely reflect resource limitations experienced by the algae, as stoichiometry indicated turf was co-limited by CO2 and nutrients while kelp appeared to be limited by nutrients but not CO2. Simultaneous enrichment of these factors would, consequently, be anticipated to facilitate the expansion of turf algae at the expense of established kelp canopies. Considerable attention has focused on the influence of altered conditions on single taxa in isolation, yet such approaches only elucidate direct response(s). In natural systems, these responses may be mediated by indirect effects resulting from interactions with other taxa. I assessed the model that biotic interactions (i.e. competition and herbivory) can counter the abiotic drivers of change. Experimental tests revealed the presence of kelp inhibits the synergistic positive effects of stressors (i.e. CO2 and nutrient enrichment) on their turf competitors, likely due to the modification of physical conditions (i.e. light availability). Similarly, rates of herbivory increased to counter the positive effects of stressors on turfs under enriched CO2 (i.e. increased grazing of turfs by gastropods). This increase in herbivory was attributable to the changes in stoichiometry of algal turfs under the greater availability of this resource. Together, these results indicate potential for indirect effects, mediated by species interactions, to counter the direct influence of altered environmental conditions. Where biotic controls are absent, however, such modification of resource availabilities may increase the probability of the expansion of novel habitats. I considered the hypothesis that where human activities combine to synergistically benefit turfs (as occurs where CO2 and nutrients are enriched), removal of one factor alone may enable further change to be slowed or recovery hastened. Experimental tests that reduced the locally-determined factor (i.e. reducing nutrients under continued CO2 enrichment) substantially slowed further expansion of turf algae, but the legacy of nutrient enrichment was not entirely eradicated. This result indicates that although management of local environmental conditions may substantially reduce the effects of entrained global change, some effects could be enduring. In summary, there was broad support for the conceptual model that cross-scale abiotic stressors can combine to interactively affect algal communities, but that such change can be countered by management of local conditions, both biotic (i.e. retaining the processes of competition and herbivory) and abiotic (i.e. removing pollutants). These results represent progress in ecological tests of hypotheses regarding global climate change as they incorporate comprehensive sets of abiotic and biotic community drivers. Further, this thesis contributes new knowledge regarding the anticipated responses of marine communities to local through global scale pollution, and the potential for local conditions to mitigate the effects of global change.

Book Description
This open access volume presents a comprehensive account of all aspects of biological invasions in South Africa, where research has been conducted over more than three decades, and where bold initiatives have been implemented in attempts to control invasions and to reduce their ecological, economic and social effects. It covers a broad range of themes, including history, policy development and implementation, the status of invasions of animals and plants in terrestrial, marine and freshwater environments, the development of a robust ecological theory around biological invasions, the effectiveness of management interventions, and scenarios for the future. The South African situation stands out because of the remarkable diversity of the country, and the wide range of problems encountered in its varied ecosystems, which has resulted in a disproportionate investment into both research and management. The South African experience holds many lessons for other parts of the world, and this book should be of immense value to researchers, students, managers, and policy-makers who deal with biological invasions and ecosystem management and conservation in most other regions.
