In contrast to previous works which have attempted to integrate ecology and physiology, Physiological Diversity adopts a completely different and more controversial approach in...

This booklet identifies some of the hidden costs of unsustainable production, and also considers examples where conservation management has failed.

The authors argue that sustainable land management is possible, and that conservation...

First, there is a soft rustle in the underbrush, then a low-slung, utterly bizarre-looking insectivore dashes in front of Eladio Fernandez. With a reflexive click of digital shutter, he's captured the reclusive ("Solenodon paradoxus"--a living fossil. A Dominican-based conservationist and photographer, Fernandez is documenting the efforts of a distinguished team of international scientists as they unravel the workings of evolution being played out on the island of Hispaniola.

A short flight from the Florida coast, Hispaniola offers unique opportunities, not just to photographers like...

Many historical processes are dynamic. Populations grow and decline. Empires expand and collapse. Religions spread and wither. Natural scientists have made great strides in understanding dynamical processes in the physical and biological worlds using a synthetic approach that combines mathematical modeling with statistical analyses. Taking up the problem of territorial dynamics--why some polities at certain times expand and at other times contract--this book shows that a similar research program can advance our understanding of dynamical processes in history.

Animals are a major link between the water column (pelagic) and the bottom (benthic) habitats in most shallow systems. This coupling is dominated by active processes such as suspension-feeding in which the organism actively uses energy to pump water that is then filtered to remove suspended particles that are consumed while undigested remains are deposited on the bottom. As a result of this feeding on and metabolism of particles, the animals excrete dissolved inorganic and organic waste back into the water column, and thus, become major components in the cycling and feedback of essential...

Fluctuations in the environmental conditions impacting life are ubiquitous. This book brings together contributions to provide readers with a comprehensive look at the challenges for ecological systems and ecological research alike. It offers a comprehensive range of topics, from environmental variability itself to its ecosystem-level impact.

Interest in beetle conservation has long been evident, with many papers treating these abundant, ecologically important and popular insects. However, this issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles, and it contains a number of papers, predominantly from outside Western Europe, to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major...

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."

Biogeography considers the distribution of biological units over a wide range of scales. The units range from genotypes, populations and species to families and higher taxa. Processes can be local, such as the isolation on islands due to sea-level fluctuations, or large-scale tectonic processes that separates continents and creates oceans. In all processes time is an important factor and by combining data on recent patterns with paleontological data the understanding of the distribution of extant taxa can be improved. This volume focuses on speciation due to isolation in island-like...
