Water is Life. Freshwater is one of the most valuable commodities on our planet, and this resource should be managed in a sustainable way. Yet, we are less than careful in the way we use water and many of our non-marine, aquatic habitats are threatened by anthropogenic impacts. Eutrophication, for example, could well turn into one of the major social as well as economic problems of the 21^st century.

Reduction of water quality also has a profound effect on the biota that depend on these water bodies, such as micro-organisms, plants and animals. Freshwater Biodiversity is...

This book provides a first synthetic view of an emerging area of ecology and biogeography, linking individual- and population-level processes to geographic distributions and biodiversity patterns. Problems in evolutionary ecology, macroecology, and biogeography are illuminated by this integrative view. The book focuses on correlative approaches known as ecological niche modeling, species distribution modeling, or habitat suitability modeling, which use associations between known occurrences of species and environmental variables to identify environmental conditions under which populations...

The Antarctic provides a suite of scenarios useful for investigating the range of climate change effects on terrestrial and limnetic biota. The international SCAR programme RiSCC (Regional Sensitivity to Climate Change in Antarctic Terrestrial and Limnetic Ecosystems) is investigating these scenarios with the goals of (1) understanding the likely response of Antarctic biota to changing climates, and (2) contributing to the development of broadly applicable theory concerning interactions between climate change, indigenous and introduced species, and ecosystem functioning. The programme...

The conflict between increasing human population and biodiversity conservation is one of the IUCN s key threatening processes. Conservation planning has received a great deal of coverage and research as a way of conserving biodiversity yet, while theoretically successful, it has never been tested. Simple lines on maps to illustrate conservation areas are unlikely to be successful in the light of human encroachment. It may be that some form of overt display is necessary to ensure the protection of reserves. This may be signage, presence of guards/rangers or physical fencing structures....

This volume contains a complete systematic treatment of the flowering plant order Asterales. This comprises 12 families with approx. 1,720 genera and about 26,300 species. Identification keys are provided for all genera, and likely phylogenetic relationships are discussed extensively. The wealth of information contained in this volume makes it an indispensable source for all working in the fields of pure and applied plant sciences.

Ecosystems are complex and enigmatic entities that are ultimately our life support systems. Understanding these systems to the point of being able to predict their behaviour in the face of perturbations requires that researchers adopt a number of strategies that vary in both approach and scale. This book, in a sense, is representative of some of the developments that have unfolded when math and physics met ecology. Here, some of the world s leading ecologists examine ecosystems from theoretical, experimental, and empirical viewpoints, from energetics to ecosystems. The book begins with...

The authors explore the communities living in The Great Lagoon, one of the biggest resting places for migratory birds in the Baltic Sea area. The book advances a food web model of the Polish part of this region, taking into account features such as the levels of consumption, production, respiration, the amount of unassimilated food, mortality, sedimentation, the accumulation in sediment and the export of individual system components.

Our species has transitioned from being one among millions on Earth to the species that is single-handedly transforming the entire planet to suit its own needs. In order to meet the daunting challenges of environmental sustainability in this epoch of human domination--known as the Anthropocene--ecologists have begun to think differently about the interdependencies between humans and the natural world. This concise and accessible book provides the best available introduction to what this new ecology is all about--and why it matters more than ever before.

An enduring controversy in evolutionary biology is the genetic basis of adaptation. Darwin emphasized "many slight differences" as the ultimate source of variation to be acted upon by natural selection. In the early 1900 s, this view was opposed by "Mendelian geneticists," who emphasized the importance of "macromutations" in evolution. The Modern Synthesis resolved this controversy, concluding that mutations in genes of very small effect were responsible for adaptive evolution.

A decade ago, Allen Orr and Jerry Coyne reexamined the evidence for this neo-Darwinian view and...

Invasive species have come to dominate 3% of the Earth s ice-free surface, constituting one of the most serious ecological and economic threats of the new millennium, and freshwater systems are particularly vulnerable. This book examines the identity, distribution, and impact of freshwater non-indigenous species and the dynamics of their invasion. It focuses on old and new invaders and provides a starting point for further research."
