...A biome is a group of ecosystems that share similar climates and organisms. In Miller and Levine Biology, 10 biomes are discussed. They are the Tropical Rain Forest, Tropical Dry Forest, Tropical Grassland, the Desert, Temperate Grassland, Temperate Woodland, Temperate Forest, Northwestern Coniferous Forest, Boreal Forest, and the Tundra. They all have a vast amount of differences between all of the biomes, and they will be discussed. Although not discussed in the book, the taiga is the biggest biome. The average temperature of the taiga is 32 degrees fahrenheit with about 12 to 33 inches of precipitation per year. There is little diversity in plant life. A few broad leaf tree species live in the taiga but mostly evergreen trees are the only ones that have adapted to really thrive in this environment. There are some animals that have adapted to live in the cold and snowy environment. A predator called the ermine has a thick coat of dark fur that turns white in the winter. The snowshoe rabbit also has a fur that turns white in the winter. The wolverine is able to mate during ideal conditions by delayed implantation in which they suspend dormant fertilized eggs until the conditions are ideal for bearing their young. Rainforests are the most diverse having more than 15 million species living in the biome. The rainforest biome is sometimes separated into two different biomes. They are referred to as tropical and temperate. The tropical rainforests are located between the Tropic...

...Biomes Tropical rainforest: * What: Hot and wet areas with broadleaved evergreen forest * Where: Within 5°N and S of the equator * Climate, limiting factors: High rainfall(2000-5000 mm yr-1), high temperatures( 26-28°) and high insolation, P>E rain washes nutrients out of the soil, so nutrients may limit plant growth * Structure: amazingly high levels of biodiversity: plants compete for light thus growing tall to absorb it, so there is a multi-storey profile to the forests called stratification. Many niches and habitat for animals and large mammals can get enough food * Net productivity: produce 40% of NPP of terrestrial ecosystems. Fast rates of decomposition, respiration and photosynthesis. Biomass gain very high, rapid recycling of nutrients * Human activity: more than 50% of world’s human population live in the tropics/subtropics forests exploited e.g. nutrients quickly exhausted by agriculture, commercial logging of timber * Issues: logging, conversion to grazing and to plantations forests exploited for economic development * Examples: Amazon rainforest, Borneo rainforest Desert: * What: dry areas usually hot in the day and cold at night as skies are clear and there is little vegetation to insulate the ground. Tropical, temperate, cold deserts * Where: cover 20-30% of the Earth’s land surface, about 30°N and S of the equator where dry air descends. Most are in the middle of continents * Climate, limiting factors: water...

...MEDITERRANEAN SCRUB Mediterranean forests, woodlands, and scrub biome, as defined by the World Wildlife Federation, is known for dry summers and rainy winters. Summers are typically hot in low-lying inland locations but can be cool near colder seas and oceans. Winters are typically mild to cool in low-lying locations but can be cold in inland and higher locations. The Mediterranean forests, woodlands, and scrub biome occurs in the world's five Mediterranean climate zones, on the west coast of continents in the mid-latitudes, the Mediterranean Basin, Chilean Mattoral, California chaparral and woodlands ecoregion of California and the Baja California Peninsula, Western Cape of South Africa, and last but not least the Southwest Australia corner area. These regions are home to a great amount diversity of habbitats and species. Vegetation types range from forests to woodlands, savannas, shrublands, and grasslands; landscapes are common, where differing vegetation types are interleaved with one another in complicated patterns created by modifications in soil, exposure to wind and sun, and fire history. Much of the woody vegetation in Mediterranean-climate regions is sclerophyll, which means 'hard-leaved' in Greek. Sclerophyll vegetation generally has small, dark leaves covered with a waxy outer skin to retain moisture in the dry summer months. All these ecoregions are extremely distinctive, harboring 10% of the Earth's plant species. This is equivalent to about 40% of...

...The chaparral biome is a temperate shrub land biome found in all five parts of the world with a Mediterranean, dry, coastal climate. The chaparral is primarily found in California and the Baja California Peninsula, Mexico. The chaparral is also found around the world in Chile, South Africa, and Western and Southern Australia. The chaparral’s climate is defined by mild, wet winters and hot dry summers. Plants of the Chaparral Plants of the chaparral must survive long periods of heat, fire, and drought. Many plants of the chaparral very closely resemble plants of the desert that can also survive long periods without rain. The South African Chaparral contains many species of plants that are not located anywhere else in the world. Examples...

...A biome is a major biological community that occurs over a large area of land. Each biome is characterized by precipitation, temperature, wind, soil conditions, availability to water, amount of sunlight, and land. For example, the taiga is very cold in the winter, hot and humid during the summer, receives 30-85 cm of precipitation annually, and the soil is thin and poor in nutrients. There are different types of biomes and each of them have different characteristics. The tundra is the coldest of all the biomes. The temperatures range from -40 degrees Celsius to 18 degrees Celsius. (Mission Biomes, N.D.) The precipitation ranges from 150 to 250 mm of rain per year. (Mission Biomes, N.D.) According to the article Mission: Biomes, there are almost no trees due to short growing season and permafrost; lichens, mosses, grasses, sedges, shrubs. (N.D.) Tundras are located south of the ice caps and extend across North America, Europe, and Siberia. Tundra winters are long, dark and cold. The temperatures are below 0 degrees Celsius for six to ten months. Animals hibernate during the winter because it is so cold....

...Biomes have changed and moved ordinarily amid the historical backdrop of life on Earth. There are fourteen biomes on the planet. Fields are isolated into savanna and mild prairies. The sea-going classification is partitioned into freshwater, freshwater wetlands, marine, coral reef and estuaries. Earthbound biomes are significant districts in the Earth that have a similar atmosphere in spite of being in various geological areas. The sea-going biome is the biggest of them all. Tundra The tundra is the coldest biome and is a treeless territory. The tundra is described by low temperature, little precipitation, low supplements, and organic assorted qualities. The Tundra has a considerable measure of vegetation inside this biome. Some regular plants...

...Discussion—Biomes, Development, Pollution, and You Each part of the United States has at least one ecological crisis based on location, biome, and industrialization pattern. For example, the Midwest was once a prairie with very fertile soil. However, when people realized that with the right watering and drainage system this area could become productive farmland, there arose ecological problems. The conversion of the prairie to farmland is the root cause of many ecological problems in this region. Regardless of what biome you consider, humans have likely had an impact on the ecology of that area. For this assignment, identify the biome in which you live. The following are a few examples of biomes: * Temperate forests: The temperate forests have variable temperatures, high moisture levels, and higher species diversity. * Taigas: These biomes have colder average temperatures, lower moisture levels, and lower species diversity. Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following: * Explain how humans have impacted the biome in which you live. List the types of environmental damage that have been caused and the species that have been impacted. * I live in Georgia, in the deciduous forest area. Human have impacted this biome as people continue to cut down the trees. We rely on trees since they provide oxygen for all living species. * Describe the major pollution issues for your biome, and...

...The Arctic and subarctic regions Compared with other biomes, the tundra biome is relatively young, having its origin in the Pleistocene (1,600,000 to 10,000 years ago). Individual plant and animal species of the tundra, however, probably first appeared in the Late Miocene (11.2 to 5.3 million years ago) or Early Pliocene (5.3 to 3.4 million years ago). Coniferous forests were present on Ellesmere Island and in northern Greenland, the northernmost land areas, in the mid-Pliocene (2.5 million years ago). Most paleoecologists believe that tundra flora evolved from plants of the coniferous forests and alpine areas as continents drifted into higher and cooler latitudes during the Miocene (23.7 to 5.3 million years ago). The Antarctic region Antarctica has been isolated from other continental landmasses by broad expanses of ocean since early in the Tertiary Period, about 60 to 40 million years ago. Prior to its separation it existed, along with Australia, South America, peninsular India, and Africa, as part of the landmass known as Gondwanaland. This long separation has impeded the establishment and development of land-based flora and fauna in the Antarctic. Other significant factors that have hampered terrestrial biotic evolution are the harsh climate, the ice cover that completely engulfed the continent during the Pleistocene glaciations, and the present limited number of ice-free land areas, which are restricted primarily to the coastal fringes and nunataks (mountain peaks surrounded...

...be classified as either biotic or abiotic. Biotic factors are other living things that may affect a particular organism, for example predators. In contrast, abiotic factors are nonliving things that affect a particular organism, such as a drought or excessive rain. In reviewing the local ecology and environment of the Commonwealth of Virginia, we must first determine the region’s biome. A biome is the classification of a terrestrial community, primarily determined by climatic factors, such as precipitation patterns and temperature ranges (Enger, Ross, & Tillery, 2009). A biome also provides an indication of the type of plant life and animals that may be present within a particular region. The relationship is interdependent between a biome and the ecological communities contained within it. An ecological community is “an assemblage of co-existing, interacting species, considered together with the physical environment and associated ecological processes, that usually recurs on the landscape” (The Virginia Department of Conservation & Recreation, 2012). When reviewing the biomes of the world, we see...

...Lemurs in Madagascar SCI/ 275 March 16, 2014 Lemurs in Madagascar 1.) What are Madagascar’s biomes? Discuss the latest features of at least one of these biomes. Using the world’s terrestrial map in Wiley Plus, Madagascar’s biomes includes; tropical rain forest, tropical dry forest, and desert. Madagascar is largely made up of the tropical rain forest biome. Its features include warm weather throughout the year with rainfall occurring almost daily. In the rainforest, human population growth and industrial expansion threatens its survival. 2.) What changes happening in Madagascar are posing challenges for lemurs? Provide details about the sources, time scale, and type of change. The changes that are happening in Madagascar that poses a challenge for lemurs, are the rapid environmental changes caused by humans. Deforestation of the rain forest disrupts the eco- system. As a result, the changes are occurring at a rapid pace, faster than the resources can replenish themselves. 3.) Which types of lemurs are adapting to the changes? Which types of lemurs are not adapting well? Why? The type of lemur that is adapting to change is the ring- tailed lemur. The ring- tailed lemur is able to adjust because of its ability to adjust to secondary habitats. On the hand, bamboo lemurs are not adjusting well to the changes. They thrive on eating the bamboo found in the forest. Once the bamboo are depleted, they will not be able to survive. 4.) What behavioral...

...(a)The species have been carried by marine trade on the hulls of ships and in bilge and ballast water and the movements tend to be between developed areas, reflecting trade patterns. Some areas are not involved; these tend to have less trade. There may be some specific knowledge of individual species from Figure 3 which should be credited, as should other species not shown on Figure 3 (rats). The major disruption is to food chains, as the alien species out-compete existing species reducing their numbers or even causing extinction. This can be directly through predation, or indirectly by occupying ecological niches. There is also the possibility that disease might be spread by new species, and in some cases damage to the physical make up of ecosystems (erosion). Biodiversity can be severely reduced, and in the worst cases ecosystems collapse. Level 2 5-7 Structure is satisfactory. Does explain the pattern with some clarity. Some understanding of impact on ecosystems and uses some geographical terminology, but incomplete; makes reference to map. Explanations are clear, but there are areas of less clarity.

...Explain how different factors can influence the variations in global biodiversity (10 marks) The biodiversity of the planet Earth is the total variability of life forms. There are around 1.9 million extant species. There are many factors that can influence the variations in global biodiversity which can be either physical or human. The size of an area heavily decides the variations in biodiversity. The bigger the area, the larger the biodiversity, as large continuous biomes can support a wider range of species and extensive boundaries can encourage migration. Also, a larger area is more susceptible to a variety in climate, which can support a variation in species. A good example of this factor taking place is the Amazon Rainforest. This vast area of 5,500,000 sq.km located in the Amazon Basin of South America has the largest collection of animal and plant species in the world, as wet tropical forests are the most species-rich biome. It is home to 10% of the world’s known biodiversity. History and age shows that older and least disturbed ecosystems, is where there is generally higher biodiversity, especially in the tropics, where there are few physical constraints on productivity. Older ecosystems have a greater biodiversity as there is a longer time period for new species to evolve. Not only for new species, but also for migratory species such as birds. Disturbed ecosystems, where deforestation and land reclamation occurs, decreases biodiversity by destroying habitats and...

...Grasslands are one of the most widespread vegetation types worldwide, accounting for nearly one fifth of the earth’s land .They represent the most important sources of livestock forage, biodiversity, and contribute to the aesthetics and diversity of rural landscapes. Furthermore grasslands play a vital role in global carbon cycling and biodiversity of conversation. There are six terrestrial biomes with which grassland is a part. The five other includes tundra, desert, taiga, deciduous forest and tropical rainforest. Grassland biome includes prairies and open fields and has a wild distribution. It is subjected to all variations of temperature in the temperate zones, from freezing to extremely cold temperatures. It undergoes all the vicissitudes of seasonal climatic factors of wind, rain, and etc. (Elton, C.S., 1927). Elton, C.S. on his book on “The Ecology of Invasion by Animals and Plants, 1958” added that, the physical factors that affect grasslands include temperature, light intensity, wind direction and wind velocity, amount of rain or breeding places. First, temperature being an important factor affects animals inhabiting grasslands in such way that any changes in the temperature can affect the optimum temperature required by these animals, therefore alters their metabolic body activities. Light intensity is another factor that affects grasslands because producers in that area undergoes photosynthesis which requires light that will be used up by animals that depend on plants...
