3.3 Terrestrial Biomes

Marine cyanobacteria include the smallest known organisms. The distribution of various types of wetlands within terrestrial biomes is mostly influenced by the amount and permanence of surface water and the availability of nutrients. Consequently, all of the southern ecozones of Canada also extend into the United States. Global temperatures vary with the angle at which the sun's rays strike the different parts of the Earth's curved surface. A MinuteEarth video about the global climate patterns which lead to subtropical deserts.

Biomass (ecology)

the most diverse biomass is found in which two biomes

Most regions of boreal forest are subject to periodic disturbances, usually by wildfire, but sometimes by windstorms or insect epidemics. Some of the most productive fisheries occur in upwelling areas, such as those off the west coast of South America and extensive regions of the Antarctic Ocean. These damaging changes are most intensive in regions where people live and work in high population densities, such as in the southern regions of Canada. A much smaller population of western monarchs undertakes a migration to roosts in coastal southern California. Not coincidentally, these areas of the planet where biomass is already most concentrated are now attracting the interest of companies wanting to produce biofuels, biobased chemicals and bioelectricity.

Which Biome Has the Least Biodiversity?

Seed plants in the desert produce seeds that can lie dormant for extended periods between rains. Open-water areas of marshes have floating-leaved plants, such as water lily and lotus. This pattern is well known for the millions of migratory birds that venture to Canada to breed in the summer, but spend the winter in warmer climes, and it is also true of some other kinds of animals. The crew of Untamed Science particularly like the rainforests of Central and South America, but we have many other favorites as well. For similar reasons, the turbidity is greatest during times of high water flow.

Many of the important issues facing modern society are the consequences of the way humans, past and present, use and change biomes and how that has affected the biodiversity in them. Urban-industrial techno-ecosystems are typical of urbanized areas and are dominated by the dwellings, businesses, factories, and other infrastructure of society see Chapter 25. A particular biome and its biodiversity have both potential and limitations for human settlement and meeting human needs. In contrast, the substrate of places with vigorous water flow is rocky because fine particles have been eroded away. Biomes are characterized by the life forms of their dominant organisms, but not necessarily by their particular species. However, the driest month of a tropical rainforest can still exceed the annual rainfall of some other biomes, such as deserts.

Tropical Rainforests

These plant communities are much more productive than those on the prevailing polar desert that surrounds the lowland, and consequently the oasis supports relatively large populations of animals. Semi-natural habitats used for the grazing of livestock also support some indigenous biodiversity. Ecoregions are sub-ecozone units, and are characterized by regional factors related to climate and landform and, to some degree, by soil, vegetation, fauna, and land-use. This sort of work allows scientists to understand the physical, chemical, and biological factors that govern the structure and function of ecosystems and sustain their species. Typical animals include birds and reptiles. There are also anthropogenic ecosystems that are strongly influenced by humans and their activities, such as cities and agricultural land. Less-deliberate anthropogenic influences, such as pollution and disturbance, also affect the character of human-dominated ecosystems, often by causing ecological damage.

Ecosystems: Biomes

The classification of global biomes described here is modified from a system proposed by the ecologist E. The boreal coniferous forest taiga is extensive in northern regions of Canada, Alaska, and Eurasia. Almost every rainforest you might visit has a temperature range of 93°F to 69°F. A biome is a large geographical region where certain types of plants and animals thrive. These soft-bottom ecosystems are usually dominated by invertebrates, especially molluscs, echinoderms, crustaceans, and marine worms. It can include , plants or animals.

Cold year-round with harsh winters, the taiga has low animal diversity. However, biomes are not homogeneous, and they contain other kinds of less-widespread communities. The last generation of the year, which transforms into adults in September, is the one that undertakes the astonishing southward migration to the wintering roosts in Mexico or California. As principle director of Untamed Science productions his goal is to create videos and content that are both entertaining and educational. There are also five species of reptiles considered endemic to the Namib. Coral reef photo by Marguerite Gregory © 2004 California Academy of Sciences.

Tropical Rainforests

Under these conditions, soil moisture is adequate to prevent desert from developing, but insufficient to support forest. Because ecozones are identified on the basis of their natural biophysical features, which are not related to the political boundaries of countries, the southerly ecozones of Canada extend into the neighbouring United States. Typical animals include snakes and birds. The increased nutrient supply allows these areas to sustain high rates of primary productivity. Thus, this energy is available for species to use and diversify. Low-growing plants such lichen and grasses are common in tundra. Freezing winters and warm, wet summers and a longer growing season than the boreal forest.
