To study the distributions of plant and animal species across the surface of the 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 of energy and materials in a particular environment. It is the basic ecological unit of study. 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. Plants and animals disburse throughout the earth and occupy habitats favorable for their survival. A habitat is the specific, physical location of an organism. Each species has specific habitat parameters (temperature, moisture and nutrient availability). Within a habitat, organisms "occupy" a

Extractions: BIOMES - Major Ecosystems of the World WORLD DISTRIBUTION OF BIOMES, ECOSYSTEMS, SPECIES BIOGEOGRAPHY - the study of the distribution of species BIOMES are the largest discernible subdivision of the biosphere with similar life forms (deserts, grassland, rainforest, etc.); it is a kind of ecosystem that can span continents. Biome boundaries of North America Biome boundaries of the World Biome boundaries and life forms that are present are determined by climate. Climate is the average temperature and moisture conditions present in an area. Climate influences the vegetation present ( See Fig. 7.15 or Figure B2 ). Areas with low rainfall and warm conditions are deserts; areas with high rainfall and hot conditions are rainforests; areas with low rainfall and cold conditions are tundra, etc. Similar biomes occur in different parts of the world: rainforests occur in Africa, Asia, and South America. Biomes can differentiated by the plants and animals present; they are adapted to their biome's cliamte. Rainforest plants have specific tolerance limits for high temperature and high precipitation. Desert cacti are adpated for high temperature and low precipitation. What would happen if we moved a rainforest fern to a desert or a cactus to a rainforest? Different species are present in the same biome in different parts of the world. Example: trees in the northern coniferous forest (taiga) in Canada and Russia are different species, but look similar. Species in the same biome have undergone similar evolutionary pressures.

To study the distribution of plant and animal species across the surface of the 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 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

Insects Home Eastern Wildflowers General Topics Natural History Ecology Family Environment Evolution Home Education Home Conservation Geophysics Paleontology Commercial Organizations Buy Books about Tundra In the polar regions of the Northern Hemisphere where the winters and extremely cold and long and even conifers cannot survive, the land is dominated by a mixed grassland, small shrub, and herbaceous plant ecosystem called the tundra. The most characteristic feature of the tundra is permafrost, a layer of permanently frozed subsoil. In the summer the ground thaws to a depth of a few centimeters and becomes wet and soggy. This freezing and thawing cycle crushes the roots of plants keeping them small and stunted. Alpine ecosystems are mountain top versions of the tundra. TUNDRA The Arctic Ecosystem . Environment Canada. A wonderful web site on the arctic-tundra ecosystems of Canada. There is a map of the region divided into its various subdivisions with descriptions and maps of each smaller region.

Extractions: 3) Study of spatial variability of plants and animals and other organisms (MacDonald). 4) These Definitions do not make the ecosystems approach explicit. Ecological biogeography concentrates on the distribution of communities or ecosystems and how this geography affects ecosystem function and persistence. B. Two broad approaches within Biogeography: Historical-Taxonomic-Evolutionary Biogeography: The study of biogeography informs our understanding of how evolution both micro and macroevolution occurred. Includes Analytical Biogeography which searches for laws or rules of evolutionary biogeography. Ecological Biogeography: Study of distributions of communities, ecosystems, and biomes.

Explain why many species can coexist in an ecosystem when they are competing for limited resources. The location on earth of particular biomes (biogeography) is largely determined by the climate of an area, especially the annual rainfall and temperature. Describe and explain the effect the following have on the climate of an area: Describe the characteristics of the following major terrestrial biomes: tundra, desert, prairie (grassland), temperate deciduous forest, temperate rain forest, tropical rain forest.

Introduction To Biogeography biomes include tropical rainforest, savanna grassland, boreal forest and sea levelrise on ecosystems, we use an approach known as Historical biogeography. 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.
Introduction To Biogeography A typical climate diagram used in biogeography is divided into The classificationof biomes has been complicated by the alteration of ecosystems by humans http://www.valdosta.edu/~grissino/geog4900/lect_10.htm
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.

Yet in most areas substantial vegetation growth occurs, even in arid regions. Here a considerable variety of grasses, annual and perennial herbs, smaller and larger shrubs, and small trees demonstrate how many Australian species have been very successful in adapting to both highly infertile soils and to dry (but variable) climates.
