Biomes
One way of understanding differences in the ecological makeup of the earth’s surface is to divide it into biomes. A biome is an ecological zone whose uniformity is defined by the type of plant life that dominates within it. This makes sense for scientists because plant life will often give a strong indication of other ecological features of a zone, such as animal life and soil type. Because biomes are defined by plant life rather than region, some biomes can stretch around the world. For example, the biome known as the Boreal Forest (Boreal means “northern”) covers much of northern Europe, Russia, and Canada. The Boreal Forest is defined by the predominance of conifers (trees with needles, not leaves). There is more than one way to divide up the world’s biomes, but most divisions are variations on or combinations of the following commonly used categories: boreal forest (conifers), temperate forest (hardwoods or mixed hardwoods and conifers), tropical forest, desert, alpine (mountain) zone, grassland, and tundra. One commonly cited biome that doesn’t easily fit within these other divisions is the chaparral or Mediterranean shrubland, which is found in European, North African, and western Asian coastal lands along the Mediterranean, as well as in coastal California. The chaparral features hardy shrub-like plants that have evolved to conserve moisture from winter rains during a long, arid summer. Biomes support the same types of organisms no matter where they are located on the planet. These organisms often have different genetic lineages and are similar only in that they have adapted to similar conditions.

GLOSSARY ... ABOUT CHAPTER 9: Introduction to the Biosphere (l). Primary Productivity of Plants Introduction The bodies of living organisms within a unit area make up a standing crop of biomass More specifically, biomass can be defined as the mass of organisms per unit area and is usually expressed in units of energy (e.g., joules m ) or dry organic matter (e.g., tons ha or grams m ). Most of the biomass in a community is composed of plants, which are the primary producers of biomass because of their ability to fix carbon through photosynthesis . This chemical reaction can be described by the following simple formula:
O light energy C H O
The product of photosynthesis is a carbohydrate , such as the sugar glucose , and oxygen which is released into the atmosphere ( Figure 9l-1 ). All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight (

PMIP 2 Vegetation Maps For The Mid-Holocene And Last Glacial Maximum
Data description
The published version of the BIOME 6000 database (Version 3: Prentice et al., 2000) was based on maps produced on a region by region basis over a number of years. Here, we have fused the information from the various regions and standardised the biome names. We recognise 40 biomes, using names that are broadly consistent with the BIOME4 equilibrium biogeography-biochemistry model (Kaplan et al., 2003). Since Version 3 of the BIOME 6000 database was released, there have been three new palaeovegetation mapping initiatives. Harrison et al. (2001) added a number of sites from the continental shelf east of China which date to the last glacial maximum. The Pan-Arctic Initiative (PAIN) extended the site coverage from the high-northern latitudes at both 6000 yr B.P. and the last glacial maximum (Bigelow et al., 2003). Pickett et al. (2004) extended the coverage to the SEAPAC (South East Asia and the Pacific) region at both 6000 yr B.P. and the last glacial maximum. These data sets are included in the current version of the BIOME 6000 data set (Version 4.2). BIOME 6000 Version 4.2 has records for 11166 modern sites, 1794 sites at 6000 yr B.P., and 318 sites at 18,000 yr B.P.

    Community Structure and Ecosystems
    Important Vocabulary Biogeography - the study of the geographic distribution of plants and animals. Biome - a major regional community characterized by the dominant forms of plant life and the prevailing climate; also known as a vegetation zone. Ecotone - areas when the vegetation and animal forms are a mixture of two different vegetation zones or biomes. Water holding capacity - the capacity of a soil to hold onto water when the water is available. Species diversity - the variety of life forms found on earth. Diversity index - a mathematical measure of species diversity in a community. Diversity indices provide more information about community composition than simply species richness; they also take the relative abundances of different species into account. Simpson's Index (D) is a type of diversity index. Species richness - the number of species present. Evenness - the same number of individuals in each species. Environment is defined by the Oxford English Dictionary as "The conditions under which any person or thing lives or is developed; the sum-total of influences which modify and determine the development of life or character." The earth has four components that make up the environment.

    C.2. VEMAP Model Intercomparison
    The Vegetation/Ecosystem Modeling and Analysis Project (VEMAP) compared three biogeography models, MAPSS (Neilson, 1995), BIOME2 (Haxeltine et al., 1996), and DOLY (Woodward and Smith, 1994; Woodward et al., 1995) and three biogeochemistry models TEM (Raich et al., 1991; McGuire et al., 1992; Melillo et al., 1993), CENTURY (Parton et al., 1987; Parton et al., 1988; Parton et al., 1993), and BIOME-BGC (Hunt and Running, 1992; Running and Hunt, 1993). The two classes of global models were intercompared and loosely coupled for an assessment of both model capabilities and the potential impacts of global warming on U.S. ecosystems (VEMAP Members, 1995). The VEMAP process determined that all the models have roughly equal skill in simulating the current environment, but exhibit some divergences under alternative climates, in some cases producing vegetation responses of opposite sign. Given the timeframe of this IPCC special report, only MAPSS and BIOME3 were able to provide global simulations. MAPSS and BIOME2 (a precursor to BIOME3) were found to produce generally similar results under the future climate scenarios of the VEMAP process. However, MAPSS is consistently more sensitive to water stress, producing a more xeric outcome under future climates and it also has a more sensitive response to elevated CO
