Tundra Biome

The arctic tundra is the worlds youngest biome. it contains the last set of continental glaciers from about 10,000 years ago. As the glacier went away it scraped away the soil from underneath, leaving bare rock. Before plants were able to grow the arctic tundra had to develop soil. Soil forms very slowly on the tundra because the cold weather slows the rate at which chemical reactions occur. Only a thi layer of soil has formed in the thousands of years since the glaciers retreated. The Southern part of this tundra is mostly made up of bare rock. There is little plant life in the tundra biome because the soil there isn't nutritious for certain plants to grow. The soil there is very much like sand, and the plant there have made many adaptations to survive in the tundra. Many of the plants have formed fuzzy hairs to keep warm, and some have developed a low root system or grow close to the ground to prevent permafrost and to keep out of the winds path. The plants of the arctic tundra have developed special characteristics so they can live in the tundra. Many animals inhabit the tundra. Each animal has adapted in their own special way. The Arctic Fox and Polar Bear both have thick coats to keep them warm in the freezing climate. The Caribou better known as the Reindeer have long antlers, and very large hooves to help climb up steep mountains or rocks. Every animal in the tundra has something to help them with the chilly climate. The arctic tundra is found in Alaska, northern Canada, edges of Greenland, northern Scandinavia, northern Russia, and Siberia. It is the youngest, coldest, and least populated biome in the world. The floor of the tundra is permanently frozen from four inches all the way up to three feet. In winter it can get down to -95 degrees and in summer it only hits 50 degrees. The tundra gets six to ten inches of snow each year. Wind…...

The Tundra

...The Tundra About a fifth of the land surface of the earth is tundra. The tundra is found next to the icy zones in the arctic. The temperatures on the tundra are below freezing and can drop to as low as -70 degrees F. There are winds that can blow up to 100 miles an hour. Temperatures are so cold, the water in the ground freezes, up to a depth of 2000 feet or more. It can reach temperatures of up to 50 degrees F on a warm summer day. There are a few places where only a few inches on the top layer of ground will thaw. This part of the thawed ground is called the active layer. This active layer is always wet because the water from the melted ice cannot drain. The frozen ground that never thaws is called the permafrost layer. The tundra may get less than five inches of precipitation a year, but it is still very wet in the summer. The water that comes from the melting ice has nowhere to go. During the summer, the tundra is one big open, rolling area of ground, covered with many small lakes and ponds. During the summer, days are close to 24 hours long. This is when there is light for the little plants that grow. The plants in the tundra are only about four inches high, many being perennials. The plants consist of grasses, sedges, mosses, little flowering plants, and tiny dwarf willow bushes. They grow in dense round cushions or mats that hug the ground. Hugging the ground helps protect them from the cold and drying winds. In the rocky area, lichens grow on the......

Tundra

...The biodiversity for the tundra forest is low. For each organism that sees any kind of fluctuation, you will see fluctuation in the organisms that consume it. For example, if a hare’s population, for whatever reason, was to decrease, you would also see a decrease in population for the Brown Bear, Arctic Fox, and Polar Bear. The variation of plant and animal life in the tundra is important in order to sustain life as well as a means to control the population of each organism. Biodiversity Biodiversity is the variety of all living things. It is made up of the following: Genetic Diversity -The raw material that makes adaptation and microevolution possible in an environment. Species Diversity - The variety of species in an environment. Ecosystem diversity - The organisms and abiotic factors of an environment. Trophic Structure A trophic structure is the feeding relationship among the various species in a community. Producers use light energy to power the synthesis of organic compounds. They are called autotrophs and are the base for all food chains. Consumers, also known as heterotrophs, depend on producers, either directly or indirectly. Herbivores are plant eating consumers and primary consumers. Carnivores, meat eating consumers, and omnivores, both meat and plant consumers, are secondary consumers. Tertiary consumers are carnivores that eat secondary consumers and quaternary consumers are carnivores that eat tertiary consumers. Not all consumers eat other......

People of the Tundra

...“Peoples of the Tundra” By Dr. John Ziker Dr. John Ziker in Chapter One of “Peoples of the Tundra” (2002) recounts how the indigenous people of Northern Siberia in the Taimyr Peninsula have managed, and dealt with the problems of the economy from the breakup of the Soviet Union since the early nineties. In this chapter Dr. Ziker explains the region and the main cities such as the capital Dudinka, the town east of Dudinka, Norisilk, and the town where he did his research, Ust Avam. He introduces the two tribes he did his fieldwork on, the Dolagans and Nganasans, whom were introduced to him by his friend Boris Molochanov. The first main point of the chapter were how the Dolagans and Nganasans were paid decent salaries in the exchange of goods from their foraging expeditions before the fall of the USSR, how they could easily transfer meat and fish to the market since government was paying for the costs. When the fall of communism happened, the money from the government put into the hunting and gathering disappeared. Traveling became too expensive since there was no money from the state, and so it became hard to keep the stores stocked with fish and meat. The Dolagans and Nganasans are people of the land, so they transitioned back to their traditional ways of distribution, sharing what they had killed, caught, or gathered with other tribesmen, which is also known as a “Subsistence Economy.” The other main point was Dr. Ziker wanted to test out three models that came from the...

Biomes

...Desert SCI/230 11/11/2012 Yasmin Henry Desert biomes can be defined as sandy regions that have very little rainfall as less than 50 cm a year with extreme temperatures and very scare vegetation. The fact that deserts are so dry the temperatures can change drastically, during the day temperatures can be as hot as 32 degrees Celsius, but at night temperatures can drop as low as -4 degrees Celsius because when the sun goes down there is no moisture in the air to trap the heat so it escapes into space creating cool temperatures. The organisms that can be found in this ecosystem are the following: Organisms in Ecosystem Cactus Wren | Desert Lark | Fat Sand Rat | Gila Monster | Great Jerboa | Horned Lizard | Rattlesnakes | Roadrunner | Thorny Devil | Camel | Lappet Faced Vulture | Sidewinder | Fennec Fox | Great Mouse Tailed Bat | Addax | There is not much benefit of this biodiversity within this ecosystem. The extremely hot temperatures and the very little rainfall makes it hard for trees to grow. Because there is limited water the few animals that live in this ecosystem have adaptations that help them survive. Major organisms in Ecosystem (P) Producers | (C) Consumers | (D) Decomposers | Cactus | Horned Lizard | Earthworms | Desert Shrubs | Great Mouse Tailed Bat | Millipedes | Soap tree Yucca | Desert Tortoises | Bacteria | Jumping Cholla | Water-holding frog | Fungi | There are three major categories of all living organisms’......

Rainforest Biome

...locations that I would have to write a book to list them all. Two that I noticed in particular were the Eyelash Viper and the Iguana. The plant lives in the tropical rainforests are divided in two parts, the canopy and the understory. Much of the understory is small shrubby plants, such as Angel’s Trumpet – a shrub native to Brazil. The canopy, though, consists of many trees and vines. The vine Allamanda is very common in South America and is found hanging from trees such as the Ficus. http://www.rainforest-path.com/tropical-rainforest-locations.html http://www.ecuador-travel.net/biodiversity.mammals.sloth.htm http://en.wikipedia.org/wiki/Rainforest http://www.blueplanetbiomes.org/rnfrst_plant_page.htm http://ths.sps.lane.edu/biomes/rain3/rain3.html http://www.rainforest-alliance.org/kids/species-profiles/tree-frog...

Biomes or Aquatic Zones

...Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? at least 150 words in length. Support your claims with at least two references to support of your position. Cite your sources. “Many anthropologists postulate that as Paleolithic people migrated to new lands with advanced hunting technologies, they hunted existing large animals to extinction, creating the first human-caused environmental catastrophe.” (Turk, J., & Bensel, T.2011) Human’s area species. We directly depend on thousands of other species for our survival, and each of them depends on thousands of others, and each of them depends on thousands of others, and so on. An extinction "event" occurs when the collapse of one species leads to the collapse of others. Evidence suggests that several "mass extinction events" have happened in the past that wiped out half or more of all of the species living at the time. We may be witnessing the start of another mass extinction right now. We don't fully understand the "web of life" upon which we depend for our existence. What would you do, if you depended on something you didn't understand to keep you alive, and one day, you noticed that it was changing into something else? Would you try to stop it from changing? or would you just wait to see what happens next? Extinction is a natural selection process. However anthropogenic impact......

Marine Biomes

...Marine Biomes Shonda Morton October 20, 2013 SCI/230 Paula Roberts A marine biome is a large aquatic zone that takes up almost 75% of Earth’s surface, has a salt concentration around 3%, and is distinguished from other biomes by its physical environment. According to Campbell Essential Biology with Physiology, (2010), the habitats of a marine biome varies depending on the level of the sea that it exists (pp.382). The layers or “zones” that make up the marine biome consist of the pelagic realm, the intertidal zone, the photic zone, the aphotic zone, and the benthic realm. The pelagic realm is the part of the marine biome that includes all open water. (Dickey, Reece, & Simon, 2010) explains “the intertidal zone is the part where the ocean surface meets land, or fresh water (pp.383).” The level of the marine biome is home to sedentary organisms such as algae, mussels, and barnacles. The photic zone was named mainly because of the fact that light is available for photosynthesis, and known as the upper or shallow layer of the marine biome. In Campbell Essential Biology with Physiology, (2010), the aphotic zone is the layer of the marine biome where the light levels are too low to support photosynthesis (pp.380). The benthic realm which exists in all aquatic biomes is the area of the seafloor, made up of sand, and organic and inorganic sediments. There are many organisms that exist in a marine biome, and each one exists at different......

Biomes

...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:......

The Artic Tundra

...The tundra artic plains completely covering most of the earth’s lands north of the coniferous forest belt. The tundra’s ecosystem is very sensitive. It doesn’t have a good ability to restore itself. Controlled by sedge, heath, willow, moss, and lichen. Plains that are pretty much alike, called alpine tundra, occur above the timberline in the high mountains of the world. Even the Antarctic area has a couple of its own arctic regions itself. The climate of the tundra is characterized by harsh winters. The average temperature in the tundra area is about –27 degrees. But what is even worse are the long night. At nights the lowest temperture recorded was –67.36 degrees. There are even times in the year when the sun doesn’t come up for days. In the tundra we have little snow and even less rainfall. The rainfall is about a quarter inch in a yearly rainfall. Even though the tundra’s winters are long a harsh there summers are the shortest season of all. Do to the terrible weather and climate in the tundra their animals and plant life is very limited. This artic tundra is mainly formed by permafrost, “a layer of permanently frozen subsoil in the ground. Putting frozen ground and flat landscape stops the drainage of water. As the water is being held up on the surface it makes ponds and bogs that give moisture for the plants, or countering the low precipitation. “The periodic freezing and thawing of the soil forms cracks in the ground in regularly patterned polygons”.

Biome

...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......

Mediterranean Scrub Biome Paper

...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...

Biomes

...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......
