Extractions: Objectives of the Biogeography Study Group (IGU-BSG) 1996-2000 The overall aim of the Study Group is to promote biogeography as a relevant sub-discipline of geography. There is some evidence that biogeographical teaching within geography might have declined in recent years, consequently the promotion of the subject is of vital importance to geography as a discipline and to strengthen biogeographical influence in international fora (e.g. IGBP). In particular, we wish to stimulate biogeographical research and teaching amongst young researchers and within developing countries. This overall aim will be achieved through the following objectives: Within the overall framework of the Study Group's activities, attention will be focused on the following issues: a) The need to understand the functioning of plant and animal communities (at scales ranging from ecosystems to biomes) and how they influence physical processes at the earth-atmosphere interface. Within this context the roles of ecosystem studies, palaeoecology, geoecology, modelling, scaling, remote sensing and GIS will be addressed. b) To provide spatial and temporal structure and explanation to the increasing amounts of information on plant and animal species that are becoming available. Within this context the roles of palaeoecology, landscape ecology, remote sensing and GIS will be addressed.

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: 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).

LECTURE 35 - TERRESTRIAL BIOMES The North American continent is the home of a diverse array of plants and animals all occupying a multitude of ecological sites in a variety of climatic regimes. The biota of North America - the sum total of its living creatures - when considered in relation to climatic, soil and physiographic features allows biologists to recognize grand associations that are termed biomes The purpose of the two lectures on biomes is to provide the student with an awareness of life from the arctic to the tropics. Our goal is to make you, the young men and women who are the future, cognizant of the living creatures, the land, and the environment of the planet. To understand the present flora, it is useful to understand in broad terms the fate of the flora over the last 18,000 years. The flora of North America has changed significantly insofar as its distribution is concern during this short period of time in the earth's history. A large mass of ice dominated much of the northern third of the continent. Unglaciated regions in Alaska allowed not only numerous plants and animals to survive in refugia, but provided a broad avenue for people to enter onto a new land. Much of the native flora was compressed in front of the ice sheet, the vast taiga of today was little more than a narrow strip along the front and down the backbone of the Appalachian Mountains.

Extractions: Home About ELC Site Map Contact Us ... Food The single factor that distinguishes desert ecosystems from other biomes is the minimal amount of rainfall received annually (no more than 10 inches). While most deserts are very hot during the day and cool at night, desert biomes are also found in arctic, icy regions. The severity and range of temperatures depend on the location- altitude and latitude- of the desert. Deserts currently cover over one third of the Earth's land surface. In some areas, such as the Sahel Desert , the desert has expanded due to overgrazing and deforestation in a process known as desertification Unlike most other biomes, one desert may look very different from the next, depending on its location. The differences are usually accounted for in moisture, temperature, soil drainage, topography, alkalinity, and dominant plant species. There are a few deserts around that world that are too dry to support plant life; deserts support a variety of plants that are well adapted for dry conditions. To conserve water, most desert plants have reduced leaves or no leaves at all. Many of these reduced leaves have further modified into spines or sharp needles which act as a deterrent to herbivores. Others plants shed their leaves for most of the year to prevent water loss, and grow them only during brief moist periods. Most plants have a very shallow root system, as well as deep tap roots (up to 100 feet) to access rainfall and groundwater. Plants found in the North American desert that exhibit these adaptations include cacti, yucca, Joshua trees, and sagebrush.
