What is the ecological role of Marine Viruses?

scientists have made a recent discovery about 15-20 years ago tha ocianic viruses are essential to the oceans health. This is because virisuses can increese the genetic divercity (a wider variety of genes). They create a different genes in some bacteria that make them stronger.

How would biodiversity be affected if coral died?

Biodiversity would collapse because coral is the main food source for countless numbers of marine life and if coral died, the marine life that thrives on coral would die as well. This would cause the fish and other sea animals that feed on the marine life that feeds on coral to die and the effect would simply snowball. It would cause the Earth a major impact and the cost of this would be very high to us.

Meaning of Biological Spectrum?

It is that the Climate determines the type of plants that can exist in each region, general appearance of vegetation is referred to as physiognomy. It constitutes general structure, shape and life forms of the species comprising the vegetation and actually the classification of vegetation type has been done on the basis of physiognomy. The individual of several species in a community can be grouped in to various life forms on the basis of their physiognomy appearance and growth performance the life form of the vegetation are the product of their genetic pool and tolerance towards the climatic variation.

The Difference Between

What is the difference between a 'formal' and 'informal' document?

an informal document is a document usually sent internally in companies to tell people what to do next or that they habve to go somewhere A formal document is a document adhering to traditional standards of correctness. A formal document is usually sent when an entity is communicating with other external entities. A informal document is a document that is not officially recognized or controlled. Eg. when an employee sends a weekly status to his direct manager. Usually informal documents are common within the same entity.

What the meaning and importance of forest conservation?

Forests provide many social, economic, and environmental benefits. In addition to timber and paper products, forests provide wildlife habitat and recreational opportunities, prevent soil erosion and flooding, help provide clean air and water, and contain tremendous biodiversity. Forests are also an important defense against global climate change. Through the process of photosynthesis, forests produce life-giving oxygen and consume huge amounts of carbon dioxide, the atmospheric chemical most responsible for global warming. By decreasing the amount of carbon dioxide in the atmosphere, forests may reduce the effects of global warming.

However, huge areas of the richest forests in the world have been cleared for wood fuel, timber products, agriculture, and livestock. These forests are rapidly disappearing. The tropical rain forests of the Brazilian Amazon River basin were cut down at an estimated rate of 14 million hectares (35 million acres) each year-an area about the size of the state of Wisconsin-in the 1990s. The countries with the most tropical forests tend to be developing and overpopulated nations in the southern hemisphere. Due to poor economies, people resort to clearing the forest and planting crops in order to survive. While there have been effective efforts to stop deforestation directly through boycotts of multinational corporations responsible for exploitative logging, the most effective conservation policies in these countries have been efforts to relieve poverty and expand access to education and health care.

In 2005 the Food and Agriculture Organization of the United Nations issued a major report, titled "Global Forest Resources Assessment 2005," on the status of the world's forests. Based on a five-year study, the report found that forested areas throughout the world were continuing to decline at a rate of about 7.3 million hectares (18 million acres) per year, an area equivalent in size to Panama or Sierra Leone. However, the rate of decline had slowed in comparison with the period from 1990 to 2000, when the world lost about 8.9 million hectares (22 million acres) of forested area per year. Africa and South America continued to have the largest net loss of forests, while forest loss also continued in North and Central America and the Pacific Islands. Only Europe and Asia showed a net gain in forested areas due to forest planting, landscape restoration, and expansion of natural forests. China, in particular, reported a large-scale afforestation effort. In 2005 the world's total forest area was just under 4 billion hectares (10 billion acres).

Clear-cutting

Clear-cutting is a forestry harvesting technique in which all the trees in a given area are removed. The advantages of this technique include the eventual production of trees of approximately the same age and height, which are easy to harvest using mechanized equipment. The disadvantages include the elimination of old growth forest and animal habitat, excessive erosion, and an unappealing landscape. In an effort to conserve forest resources, the timber industry is modifying clear-cutting techniques to include the complete use of all harvested trees and the replanting of clear-cut areas.

In the United States and Canada, forests are threatened by extensive logging, called clear-cutting, which destroys plant and animal habitat and leaves the landscape bare and unproductive if not properly reforested. Small pockets of ancient forests from 200 to 1,200 years old still exist but are threatened by logging interests. Until the 1990s, the U.S. Forest Service was directed by Congress to maximize the harvest of timber in order to provide jobs. In the late 1980s and early 1990s, however, environmentalists sued the government for violating the National Environmental Policy Act (NEPA), and heavy logging was deemed nonsustainable. As a result, the timber harvest was reduced and foresters were directed to follow a more sustainable policy called ecosystem management. This policy required foresters to focus on conserving natural habitats rather than maximizing tree harvest. Despite this change, many ancient forests remain unprotected.

How do estuaries sustain biodiversity in oceans?

Estuaries sustain biodiversity by providing a range of various habitats for many species to survive in. Birds, mammals, fish etc, use estuaries to breed, live and feed in. It is helpful in the survival of oceanic creatures and creates a sustainable area for survival.

Why are wildlife corridors important?

Without wildlife corridors, biodiversity would increase greatly as these corridors provide shelter and a method of moving from one location to another, for small, often vulnerable animals. Therefore, if they were removed, only those animals which could survive in the open and escape predation easily would remain.

Why do places near the equator have such high biodiversity?

Although it is popularly thought that high biodiversity relates to the more "benign" and less demanding environment in hot climates, recent research by Michael Huston of the University of Texas in "Biological diversity, soils, and economics" and "Precipitation, soils, NPP, and biodiversity: resurrection of Albrecht's curve", Australian ecologist Tim Flannery in The Future Eaters plus Jason Weir and Dolph Schluter in "The latitudinal gradient in recent speciation and extinction rates of birds and mammals" show that these are misconceptions.

Flannery and Huston both demonstrate that owing to the roughly four orders of magnitude greater age of their soils (except in the volcanic regions of the Pacific Rim), the productivity of the Tropical and Unenriched Worlds is very much less than those of the Enriched World of the extratropical northern and western hemispheres. Weir and Schluter show that speciation rates are much lower in the Tropical World than in the depauperate fauna of the Enriched. One would presume that with their extreme geological stability the Unenriched World of Australia and Southern Africa would have still lower speciation rates than the humid tropics. This is especially true when one considers that many birds and mammals in Australia and Southern Africa require so much labour for reproduction that most adults must serve as "helpers at the nest" rather than reproduce on their own, which acts as an extremely severe limiter on potential dispersal.

All these indicators point to the higher diversity of the Tropical and Unenriched Worlds as being due to reduced interspecific competition compared to the young and highly productive Enriched World. Soils of an infertility universal in all of the Unenriched and most of the Tropical World are exceedingly rare in the Enriched World - occurring only in a few areas of exceptionally nutrient-poor parent materials like ultrabasic rocks (serpentines, peridotites) - and then only outside of glaciation limits within which intrazonal parent materials are converted to highly fertile zonal soils. (In this context, it's notable that the most northerly major biodiversity hotspot in the Klamath Basin is one of the major occurrences of serpentines in the world, as is the very rich tropical hotspot of New Caledonia).

In the Tropical and Unenriched World resources are so scarce in unfertilised environments that co-operation rather than competition tends to be the rule to allow plants to obtain the minimal nutrition possible on these soils. The absence of competition reduces extinction rates to a fraction of the level observed throughout the Enriched World: in essence, the creation of biodiversity occurs in the Enriched World, but it is rapidly pooled into reservoirs in the Tropical World, and the Unenriched retains older species (marsupials, mousebirds) dating from periods when its ecological conditions were globally general.

Protists

What are characteristics of the kingdom protista?

  • They are eukaryotic, meaning they are not bacterias and contain a true nucleus.
  • They can be multicellular or unicellular.
  • Some are heterotrophic, others are autotrophic.
  • Some reproduces sexually and some reproduces asexually. Still others utilize both methods, asexual reproduction inside a host organism and sexual reproduction outside.
  • Many are parasitic and lives in ponds
  • The plant-like protists are thought to be the ancestors of modern plants.
  • The animal-like protists are thought to have been the ancestors of all animals.

Why to study biodiversity and germplasm conservation?

Biodiversity is important at every level1. Because we live in a complex system where every living thing depends on something else in the system, down to the tiniest contributing members. It is important that we actively pursue a clear and current understanding of the system in which we live in order to monitor and maintain it.

2. Because God made the world and everything in it, and gave it to man to cultivate, care for and protect. (spiritual version)

3. Because there are still so many species we have not yet even found. Many of these still being discovered have and will yielded volumes of information about our world and cures for our ailments. The most resent discoveries have advanced our ability to fight cancer. (humanitarian version)

4. Because Biodiversity is declining and we need to understand why, how it is going to effect us all, if we are causing it or if we can afford to help maintain it, and if it benefits us to maintain it. (political version)

5. Because biodiversity is the origin of beauty in the world and to study it is to cultivate the heart.

*6* Biodiversity is key when an ecosystem experiences a disturbance. This can be a fire, flood, disease epidemic etc. A more diverse community that have different adaptive strategies will be more likely to survive and rebound.
