Pelagic Snails
Lucid line drawings and photos, 16 in fine color. Based on some 15 years of study and collection in both polar regions and most areas of the tropics and temperate zones. Detailed treatment is given on all known pelagic snails (aoubt 140 species) including: external anatomy, swimming and buoyancy mec
The Seventh Continent
First Published in 2011. Part of the resources for the future library collection on Global Environment and Development, this is the final Volume of seven. This book presents a broad-ranging study of Antarctica's history, politics, and development prospects with a command of issues in geography, science policy, technology, and international law, which is addressed with authority and flair. At this time, nations of the world are struggling to fashion a legal framework to govern Antarctic resources, which some regard as the common heritage of mankind. This debate, described vividly here, represents an ongoing application of the common-property resource concept, which has played a prominent role in RFF's research and analytical contributions during the past quarter-century. Furthermore, the continent's energy and minerals endowment-if exploitable at all (and in the author's judgment the prospects for this are dim)-constitute at best resources for the future.
Marmots
In this book, based on over twenty years of study around the world, the author summarizes and synthesizes virtually everything that is known of the social behaviour and ecology of marmots. The organizing principle of the author's approach is evolution by natural selection - and thus, the degree to which the social behaviour of free-living animals can be interpreted as representing adaptations to particular environmental conditions. This book is essentially a single, widespread genus (genus Marmota comprising fourteen species found in North America and Eurasia. As such, it represents a productive union of theoretical insights from Darwinism and modern sociobiology, accompanied by a wealth of empirical data. Marmots are notable in that they constitute a relatively homogeneous group, made up of numerous species which greatly resemble each other. However, they occupy widely varying habitats - from temperate, lowland elevations to (more often) alpine meadows - and theory would predict behavioural adaptations to match their habitats.
Krill
Note that this book is based on Wikipedia and other public domain resources. Krill are small crustaceans of the order Euphausiacea, and are found in all the world's oceans. The name krill comes from the Norwegian word krill, meaning "young fry of fish", which is also often attributed to other species of fish. Krill are considered an important trophic level connection – near the bottom of the food chain – because they feed on phytoplankton and to a lesser extent zooplankton, converting these into a form suitable for many larger animals for whom krill makes up the largest part of their diet. In the Southern Ocean, one species, the Antarctic krill, Euphausia superba, makes up an estimated biomass of around 379 million tons, more than that of humans. Of this, over half is eaten by whales, seals, penguins, squid and fish each year, and is replaced by growth and reproduction. Most krill species display large daily vertical migrations, thus providing food for predators near the surface at night and in deeper waters during the day.
The Mediterranean Sea
This volume is an indispensable addition to the multidisciplinary coverage of the science of the Mediterranean Sea. The editors have gathered leading authorities from the fields of Marine Biology, Ecology, paleoclimatology, Chemical and Physical Oceanography, Zoology, Botany, Aquatic Photosynthesis, Socioeconomics, Mariculture, Mediterranean History and Science of Humanity. Beginning with the birth of the Mediterranean Sea and its myths. From coral to fish, an introduction is given to its major inhabitants of plants and animals past and present. The chapters illustrate how organisms interact as part of the structure and function of the Sea's main ecosystems. The rise of the Mediterranean as ...
