Biogeography The biosphere is generally considered to be "that portion of the earth in which organisms and people can live" (Odum, 1993, p.26). It merges impercephibly into the lithosphere, hydrosphere and atmosphere. (Fig 1a) Within the biosphere, organisms interact with each other and with their abiotic environment in complex ways. It is these relationships and the resultant spatial and temporal patterns of life-forms which are the main focus for biogeography (Fig 1b). Investigations are undertaken at a variety of scales : the biosphere, biomes, ecosystems, micro-habitats. The most common/useful scale used by many biogeographers is that of the ecosystem. This term was coined by Tansley in 1935 to denote biotic and abiotic components considered as a whole. "Ecosystem" is aterm which not only describes particular groups of organisms interacting with each other and with their non-living environment, but it is also a concept. Ecosystems are generally considered to be open, dynamic systems with identifiable structures and functions (Fig 2.) Any given ecosystem contains

Extractions: Mountain Station ... Contact Us Ecosystems Group T he primary aim of the Ecosystems Group is to study the ecological components of arctic and alpine systems and their interactions with climatic and biophysical variables. The Ecosystems Group has recently expanded to include study of the tropics and human dimensions. Basic research topics include: We address questions of how climatic influences, biophysical factors, and biotic components interact to control the distribution and maintenance of ecosystems; how the hierarchical organization of current ecosystems was produced in response to past and present environments; how predicted climatic changes and current and future changes in land-use patterns will affect ecosystems; and how conservation planning can contribute to sustainable ecosystems at multiple geographic scales. Ongoing projects investigate the following characteristics and scales of ecological systems: populations, species, communities, landscapes, and regions; plants and animals; biogeochemistry, ecophysiology, hydrology, patterns of biotic distribution, and biogeography; and above- and below-ground systems.

GE201 of their characteristic ecosystems or biomes and the importance of physical, CB Cox and PD Moore, 1993, biogeography An Ecological and Evolutionary http://www.usp.ac.fj/geography/GE201.HTML
Extractions: This course focuses on the nature and distribution of the world's plant and animal resources, with emphasis on the Pacific islands. Particular attention will be paid to the importance of plants and animals within the context of their characteristic ecosystems or biomes and the importance of physical, biotic and human factors in shaping ecosystems. Emphasis will also be placed on the ecological and cultural importance of plants and animals to sustainable human habitation of the earth. In this context, the ethnobotanical, ethnozoological and, in particular, the economic importance of plants and animals to Pacific peoples will be examined. The primary objective of the course is to provide a basic understanding and appreciation of the nature, distribution, and ecological and cultural importance of the world's and the Pacific Islands' plant and animal resources. More specific emphasis will be placed on: 1) their distinctive characteristics, 2) their evolution, 3) the impact of human activities on these resources, and 4) the nature of the interdependence between human societies and their biotic resources and ecosystems.

Fundamentals Of Biogeography And Ecosystems Fundamentals of biogeography and ecosystems. biogeography and ecological systems A biome may contain many different kinds of smaller ecosystems. http://www.uwsp.edu/geo/faculty/ritter/geog101/textbook/biogeography/biogeograph
Extractions: Contents News Glossary ... Biogeography of the Earth Biogeography is the study of the geographical patterns of plant and animal species. To understand the distribution of plant and animal species on Earth, a fundamental knowledge of ecology and ecosystem dynamics is required. Ecology is the study of the interactions among organisms. An ecosystem is a functioning entity of all the organisms in a biological system generally in equilibrium with the inputs and outputs of energy and materials in a particular environment. It is the basic ecological unit of study. There are two kinds of ecosystems, aquatic and terrestrial. An ecosystem is comprised of habitats, biological communities, and ecotones. A biome is often referred to as a global-scale community of plants and animals and is the largest subdivision of the biosphere. A biome may contain many different kinds of smaller ecosystems. Biomes are typically distinguished on the basis of the characteristics of their vegetation because it makes up the largest portion of biomass. Plants and animals disburse across the Earth and occupy habitats favorable for their survival. A

Extractions: A typical climate diagram used in biogeography is divided into months (x-axis) and temperature ( e.g. , 10°C intervals) on the left y-axis and precipitation ( e.g. , in 20 mm intervals) on the right y-axis. Across the top of the diagram, you have the (1) location, (2) elevation), (3) length of record, (4) mean annual temperature, and (5) total annual precipitation. Within the body of the graph, you will find (1) the curve for mean monthly temperatures, (2) the curve for mean monthly precipitation, (3) the relative period of drought (dotted), (4) relative humid season (vertical hatching), and (5) period when mean monthly precipitation exceeds 100 mm (black), if available.
Introduction To Biogeography biogeography is the study of the distribution of plants and animals over the biomes include tropical rainforest, savanna grassland, boreal forest, http://www.valdosta.edu/~grissino/geog4900/lect_1.htm
Extractions: Biogeography is the study of the distribution of plants and animals over the surface of the Earth in both a spatial and temporal context. The discipline is important because administrators, politicians, policy-makers, and consulting firms are looking more and more to scientists who study the Earth, its environs and its organisms, to better manage the future to ensure its well-being. The goal of the Biogeographer, as for all scientists, is to eventually provide rules and scientific laws , arising from proven theories, that can account for such patterns in distributions over space and time. These rules provide a general framework of understanding of our environment that can subsequently be used for predictions about the consequences of human-alteration of the natural world.

Extractions: The ecosystem is not defined by size or location. Rather is it the inclusion of energy flow and mineral cycles with all community-level characteristics that define an ecosystem. Ecologists who study ecosystems are known as synecologists and systems ecologists. The latter often use computer simulation modeling to study and understand the structure and function of ecosystems. Climate is also the major influence on the type and distribution of ecosystems. ... want to know more? Institute of Ecosystem Studies LTER - ecological studies World biomes - BluePlanet Five biomes of the world ... Ocean Planet The biome is the highest scale of integration in ecology. Biomes are not fundamentally different from ecosystems, except that biomes are defined more by their geographic scale (often continental in size) and physiognomy (characteristic appearance over the landscape, e.g., grassland, woodland, coniferous and deciduous forest). The prominent ecologist, Robert Whittaker, classified a total of 36 terrestrial and aquatic biomes, which are summarized in his classic book, "Communities and Ecosystems" (1975).
