Biogeography in the Sub-Arctic


Book Description

There is no escaping the fact that the island biogeography of the North Atlantic Region is singularly peculiar. Sitting in the north of the Atlantic Ocean, these islands have been subjected to largescale shifts in climate over the last few million years, unlike the other island groups further south which were likely more buffered from the vicissitudes of Quaternary climate changes. Uniquely for a group of islands there is only one documented extinction in the North Atlantic (the Great Auk), and those in the insects are local events relating to species that are distributed throughout the Palaearctic region. Over half the insect species in Iceland and Greenland are introduced. The faunas, excluding Greenland, are predominantly of Palaearctic origin and have close affinities with the faunas of Scandinavia and the British Isles and. These unique physical and biological characteristics have interested biologists and biogeographers for centuries. The key debates concerning the biogeography of the North Atlantic islands still rumble on: Do the biota reflect cryptic refugia or otherwise, or tabula rasa and recolonization? How important were human communities in shaping the existing biota and biogeographical patterns? Throw into this mix current concerns over global warming, and we can now ask, how resilient is the biota to change, either natural or anthropogenic? This volume draws together a range of researchers with longstanding research interests in the region, from diverse academic backgrounds, to evaluate some of these questions.

Sedimentation History in the Arctic Ocean and Subarctic Seas for the Last 130 kyr


Book Description

The book reflects the results of the study of sedimentation history, paleoclimatology, and paleoceanography of the Arctic and Subarctic during the last 130 ka. The main objects under consideration are marine basins of the West Subarctic (Iceland, Norwegian, and Greenland Seas), the Arctic Ocean (Barents, Pechora, Kara, Laptev, East Siberian, Chukchi Seas and deep-sea Arctic Ocean proper), East Subarctic (Bering and Okhotsk Seas). The modern environment and geological history of water- (ice-) sheds and marine basins have been studied for each region, using different sedimentological and geochemical proxies. Mainly results of the authors' own studies are represented, with special emphasis on glacial/interglacial variability and land-ocean interaction. The book is aimed at sedimentologists, quaternary and marine geologists, paleoclimatologists and paleoceanographers, as well as being of great interest to students in the related fields.

Ecology and Biogeography of High Altitude Insects


Book Description

In my book Introduction to High Altitude Entomology, published in 1962, I summa rized the results of eight years' studies, mainly on the Himalaya. I have since then had the opportunity of studying the collections of high altitude insects from the Alps, Carpathians, Caucasus, Urals, Alai-Pamirs, Tien Shan, Altai and other im portant mountains of the world in different museums and institutions in Europe. Through the courtesy and generosity of the Academy of Sciences of the Union of Soviet Socialist Republics, I was also able to personally collect insects and make valuable field observations on the Caucasus, the Alai-Pamirs, Ala-Tau and the Tien Shan mountains. Through comparative studies I have tried to synthesize the fundamental principles of high altitude entomology. I have described here the distinctive characters of the high altitude environment, the ecological specializations of the high altitude insects, their ecological inter relations and the outstanding peculiarities of their biogeography. I have also pre sented here an outline of the high altitude entomology of the principal mountains of the world, with brief accounts of their orogeny, geology and vegetation. This book differs from all other contributions in the field in its comparative ecological approach and in the fact that the main emphasis is throughout on the evolution of the high altitude ecosystem as an integral part of the orogeny. High mountains are, in all parts of the world, important and independent centres of origin and differ entiation of distinctive and highly specialized ecosystems and faunas.




Biogeography


Book Description

Through eight successful editions, and over nearly 40 years, Biogeography: An Ecological and Evolutionary Approach has provided a thorough and comprehensive exploration of the varied scientific disciplines and research that are essential to understanding the subject. The text has been praised for its solid background in historical biogeography and basic biology, that is enhanced and illuminated by discussions of current research. This new edition incorporates the exciting changes of the recent years, and presents a thoughtful exploration of the research and controversies that have transformed our understanding of the biogeography of the world. It also clearly identifies the three quite different arenas of biogeographical research: continental biogeography, island biogeography and marine biogeography. It is the only current textbook with full coverage of marine biogeography. It reveals how the patterns of life that we see today have been created by the two great Engines of the Planet - the Geological Engine, plate tectonics, which alters the conditions of life on the planet, and the Biological Engine, evolution, which responds to these changes by creating new forms and patterns of life.




Biogeography


Book Description

Biogeography has been one of the great growth areas in geography in recent years, with much new research work and many new developments taking place. This book presents an authoritative, up-to-date, international review of all the major biogeographical themes. The chapters define each theme and its place within biogeography and consider the methods of study adopted. Each chapter then assesses recent trends and the latest state of the art, and concludes by examining where future developments are likely. Many case-studies and examples are provided, from throughout the world, including North America.
