Biogeography, the study of the distribution of life on Earth, has undergone more conceptual changes, revolutions and turf wars than any other scientific field.
The prime purpose of this book is to serve as a design is of considerable value in helping the classroom text for the engineering or architec- student make the transition from the often sim- ture student.
The prerequisite to investigating the underlying causes behind mass extinction is a profound understanding of the evolutionary history of both living and dead species.
A state-of-the-art review of scientific knowledge on the environmental risk of ocean discharge of produced water and advances in mitigation technologies.
This Volume contains the papers presented by twenty-eight invited speakers at the symposium entitled, "e;Genetic Manipulation of Woody Plants,"e; held at Michigan State University, East Lansing, Michigan, from June 21-25, 1987.
Conservation biology -- using concepts from traditional resource management and modern population biology to preserve biological diversity -- has emerged as one of the most important areas of ecology In order to really understand the problems of decreasing diversity and the solutions to maintaining it, the attention of ecologists must be focused on larger spatial and temporal scales than they are used to.
Monitoring Plant and Animal Populations offers an overview of population monitoring issues that is accessible to the typical field biologist and land managers with a modest statistical background.
Since the publication of the first edition more than thirty years ago, The Flora of Alberta has become the standard guide for naturalists, botanists, and all those interested in the wildlife of the province.

The extent of harmful effects of pollution on atmospheric, terrestrial and aquatic environments can be translated into extreme temperature changes, dirty air, clean water shortages, and increased incidence of toxicity that harms every life on earth.
Anthropogenic influences to the earth's system, including the atmosphere, hydrosphere, biosphere, cryosphere and lithosphere, represent a serious challenge to our planet's ecosystems and natural environments.
This volume deals with many aspects of the physical and chemical limnology of the Salton Sea, California's largest lake and a lake that may soon to be the object of a multi-billion dollar restoration project.
The volume contains summaries of facts, theories, and unsolved problems pertaining to the unexplained extinction of dozens of genera of mostly large terrestrial mammals, which occurred ca.
Microbial activities influence water-rock interaction processes and chemical transport between the major geochemical reservoirs and the formation/transformation of minerals and rocks, whereas geological processes and geochemical controls influence the microbial ecology in extreme environments.
Science is supposedly ultimately constrained by the nature of the physical world, meaning that changes in scientific methods and practice are supposed to be away from those with less utility and toward those that are more revealing, useful, and productive of insights into the nature of that world.
The rate of creation of reactive nitrogen (NR) on the earth has dramatically increased in the last half century mainly due to the production of N-fertilizer through the Haber-Bosch process, fossil fuel combustion, and the cultivation of plants that fix N from the atmosphere.
Paleopalynology, second edition, provides profusely illustrated treatment of fossil palynomorphs, including spores, pollen, dinoflagellate cysts, acritarchs, chitinozoans, scolecodonts, and various microscopic fungal and algal dispersal bodies.
Samuel Johnson (of Boswell fame) said about writing, 'whatever is written without effort is in general read without pleasure' and 'the unexamined word is not worth reading.
Observational, experimental and analytical data show that C60, larger fullerenes, and related structures of elemental carbon exist in interstellar space, meteorites, and on Earth and are associated with meteorite in impact events and in carbon-rich environments such as coals (shungite) and bitumen.
World population is increasing at an alarming rate and this has resulted in increasing tremendously the demand for tree products such as wood for construction materials, fuel and paper, fruits, oils and medicines etc.
The plant fossil record provides evidence that the genus Metasequoia was widely distributed and experienced a wide range of climatic and environmental conditions throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene.
