depletion of forest and ecological imbalance

First-ever 'State Of The Carbon Cycle Report' Finds Troubling Imbalanc.. - ScienceDaily (Nov. 17, 2007) — The first 'State of the Carbon Cycle Report' for North America, released online this week by the U.S. Climate Change Science Program, finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. North American sources release nearly 2 billion tons of carbon into the atmosphere each year, mostly as carbon dioxide. Carbon 'sinks' such as growing forests may remove up to half this amount, but these current sinks may turn into new sources as climate changes.

A result has been the buildup of carbon dioxide in the atmosphere, but....

Coastal Habitats Are The Biosphere's Most Imperiled Ecosystems - ScienceDaily (Oct. 21, 2007) — The BBVA Foundation’s Third Debate on Conservation Biology allowed leading international experts to present findings of their latest research into the scale, causes and consequences of global loss of coastal habitats. The disappearance of these ecosystems, which include coral reefs, mangrove forests, wetlands and seagrass meadows, has serious consequences like loss of biodiversity, depletion of exploitable living resources, impaired capacity of the oceans to sequester CO2 and loss of the leisure value of the coastal zone. Not only that, the coastline becomes more vulnerable to the increased erosion associated with rising sea levels.

How Plants Manage Calcium May Reduce Effects Of Acid Rain - ScienceDaily (Mar. 11, 2007) — A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in.

The research was supported by the National Science Foundation (NSF), the U.S. Department of Agriculture and Xiamen University in China. To grow, a plant needs a reliable supply of calcium, which enters the plant dissolved....

Upper Midwest Forests Are Losing Diversity, Complexity - ScienceDaily (Oct. 17, 2007) — Forests in the nation's Upper Midwest have changed greatly since the time of the early settlers. And more changes may be coming.

Schulte, assistant professor in Iowa State University's department of Natural Resource Ecology and Management and her team of researchers. 'There's been a shift in the entire ecosystem,' said Schulte, whose research has recently been published in the journal Landscape Ecology. For the study, Schulte, along with Laura Merrick of Iowa State; David Mladenoff of the University of Wisconsin, Madison; and Thomas Crow and David Cleland of the U.S. Forest Service, took forest composition information as described in the Public Land Survey from the mid-1800s and compared it with today's forests. She found that none of the areas su....

  Save Planet Earth.mp4   This video has been created by ZING PRODUCTION to spread the message to the world that, please "SAVE OUR PLANET EARTH" from increasing human interference... Fast growing industrialization, forest cutting & by going against nature, we are causing great damage to our earth & it's flora n' fauna. Ecological imbalance caused by this is resulting in global warming & continuous melting of ice in Arctic. Hence, we need to stop and do something to preserve the Serenity & Beauty of Our Earth!!! - Avinash Nikash

  What are your feelings towards the depletion of our forests?   Battlefields (2003)

Question : 1. What are the three trophic levels and give an example of each. 2. What trophic level do you think is the most important in the ecosystem and why? 3. What is biodiversity? Is it important? Relate biodiversity to the trophic levels. 4. What would happen to the rest of the trophic levels if one them was wiped out?

Answer : 1. producers, consumers, decomposers 2. Loss of any level in an ecosystem will create an ecological imbalance. 3. The productivity/biodiversity of an ecosystem depends on the rate with which organisms move between different parts in the ecosystem. You would need to find some actual studies either at the library or online, and compare the data. 4. The level that was wiped out was a source of food for others, and was keeping the population in balance. So, the food web would be in serious imbalance.

Question : the bamboo forest like the ones giant pandas live in, are those considered to be tropical dry forests?

Answer : This is a paper I found .... hope this helps ... the abstract says 'A novel landscape classification system was proposed in this study based on landscape ecological theory and the differentiation in climate, topography, soil, vegetation and land use mode. Five basic units (zone, tract, province, region and type) and two assistant units (sub and group) were used in this system. The tropical forest landscape in Hainan Island was regarded as a landscape province, belonging to global tropical forest landscape zone, Asiatic (oriental) tropical forest landscape tract and Chinese tropical forest landscape subtract. Based on the grade system of region, sub-region, type-group and type, this landscape province (Hainan Island) is divided into 6 landscape regions (east moist forest landscape, west semi-arid forest landscape, central-south mountainous forest landscape, tropical evergreen needle-leaved forest landscape, tropical bamboo landscape and tropical plantation landscape), 11 tropical fo..

Question : I know we should all play our part in conserving water and electricity but how does it affect our environment? can someone give me a summary so i can help others around me understand why they should play their role too?

Answer : ENERGY 1. thermal energy- we get by burning coal 2. hydro power- by water, through dams. 3. nuclear energy- through fission of uranium. here if you will save energy at your home or any where than there will be less extraction of coal from earth, less mining and less possibility of ecological imbalance. when dams are created a lot space gets submerged in water and loss to flora and fauna too occurs. so if save energy,there will be less dams. waste from nuclear plants are radio active they degrade the land where there are dumb and cause harm to humans too. WATER NO WATER, MEANS NO TREES AND NO TREES MEANS, NO RAINS, NO RAINS MEANS DROUGHTS AND THIS MEANS LOSS OF LIFE OF HUMANS AND ANIMALS RESULTING IN 'ECOLOGICAL IMBALANCE'.
