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

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.

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.

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.

Introduction to Biogeography 340 September 2, 2003 I. Syllabus and Stuff II. Quiz III. Intro to Biogeography A. Biogeography Defined: 1) The Science concerned with describing and explaining the distribution of organisms on Earth. 2) Is concerned with the analysis and explanation of patterns of distribution, and with the understanding of changes in distribution that have taken place in the past and are taking place today (Cox and Moore). 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.

Home Ecosystems and Biomes True or False Ecosystems and Biomes True or False Biogeography is primarily concerned with the relationships between organisms and their environment. True False An ecosystem can be defined as a self-sustaining association of living organisms and their non-living physical environment. True False The function that a life form fulfills in an ecological community is called its niche. True False In the course of their evolution, vascular plants evolved conductive tissues, called stomata, that regulate interactions between the plant and the surrounding atmosphere. True False Net primary productivity is highest in Earth's boreal forest zones, where abundant moisture combines with rich soils to create optimal growing conditions. True False The complementary processes of respiration and photosynthesis are the key chemical processes in the carbon and oxygen cycles. True False Ecological succession tends to proceed from relatively simple communities to more complex ones. Lichen and moss colonization of recently exposed rock surfaces is an example of primary succession, while changes in a forested area following a fire represent secondary succession. True False A biome is a large, stable terrestrial ecosystem with specific plant and animal communities.

Geography 4900 Introduction to Biogeography Lecture 1 I. Introduction to Biogeography 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. Notice both "spatial" and "temporal" contexts are mentioned, because biogeography is concerned with the analysis and explanation of patterns of distribution , and with the understanding of changes in these distributions that have taken place in the past and which are taking place to this day. 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. Hence, the goal of Biogeography is to

Geography 4900 Introduction to Biogeography Lecture 10 I. Climate diagrams as an aid to ecosystem classification Biogeographers have long sought a means for portraying climates in simple, condensed form that would give at a glance an indication of the main features that might be of critical importance to the organisms of the area. Climate diagrams provide this information. 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. Along the left y-axis, you find (1) the highest temperature recorded, (2) the mean maximum temperature of warmest month, (3) mean daily temperature variation, (4) average minimum temperature during the coldest month, and (5) the lowest recorded temperature. Along the x-axis, you will find (1) the months with mean temperatures below freezing (0°C) in black, (2) months when late or early season frosts are likely (hatched), and (3) mean duration of the frost-free period in days. 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.

Most of inland Australia is arid or semi-arid. 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. Module objectives When you have completed your study for this module you should be able to: describe some of the basic concepts that explain how ecosystems work describe the principal biomes that occur globally, and explain how climatic controls affect the characteristics of each describe some of the distinctive features of Australia's flora describe some features of Australia's fauna Module introduction Figure 1: Eastern Gray Kangaroo (Eungella National Park): dawn and dusk are the best times for seeing animals such as these (which are not rainforest species, living instead in cleared areas nearby)
