Essay on island biogeography

Rationale[ edit ] Models allow a better understanding of how complex interactions and processes work. Modeling of dynamic interactions in nature can provide a manageable way of understanding how numbers change over time or in relation to each other.

Essay on island biogeography

The eminent evolutionary biologist E. Known as the father of sociobiology, he is also hailed as the pre-eminent champion of biodiversity: Wilson has earned more than a hundred scientific awards and other honors, including two Pulitzer Prizes. A wildlife nursery as well as a bulwark against climate change, the vast swath of woodlands and tundra is 26 percent of the world's forest — and is at risk from resource extraction and warming.

A 2, mile long corridor from Alabama to Quebec would preserve land with some of the continent's greatest bio-diversity not far from its most populated region. New England is dense with overlapping conservation partnerships. The Staying Connected Initiative has pinpointed natural habitats to extend orange circles.

The regal evergreen's unique fire-shaped ecosystem once coveredsquare miles from Virginia to Texas; about 3 percent remains. Founded to re-establish longleaf pine forest, the Nokuse Plantation links existing protected lines — "a grand accomplishment," says E.

The high point of biodiversity likely coincided with the moment modern humans left Africa and spread out across the globe 60, years ago. Wilson recently calculated that the only way humanity could stave off a mass extinction crisis, as devastating as the one that killed the dinosaurs 65 million years ago, would be to set aside half the planet as permanently protected areas for the ten million other species.

A version of this idea has been in circulation among conservationists for some time. The one below roams at the Flying D in Montana. Davis above, with a pitcher plant on the 50,acre nature reserve he founded has been inspired by the biologist E. Wilson in blue to save wildlife, including the threatened gopher tortoise.

The signature tree of Nokuse Plantation is the longleaf pine, but cypress and other species thrive along Black Creek as it flows into Choctawhatchee Bay. The threatened gopher tortoise. Red-cockaded woodpeckers nest in mature longleaf pines and have been documented migrating over 40 miles to find suitable habitats in Florida.

Eastern Indigo snakes such as this one call longleaf pine forests home and have become endangered since the continued loss of their habitat in Georgia and Florida. Davis built the E. Wilson Biophilia Center in as an educational facility for local youth in Florida to experience nature firsthand.

Controlled fires are necessary for the health and growth of forested areas such as the Tall Timbers Research Station in northern Florida.

Those that run north-south, like the initiative in the West known as Yellowstone-to-Yukon, can let life move north as things warm up, and those that run east-west may have the benefit of letting life move east, away from the west, which in the future may not see as much rain.

The question would send me across the States, to a bison ranch in Montana and to emerging wildlife corridors in New England, but according to Wilson, the pathway to a planet permanently half-protected—something he thinks we could accomplish in half a century—begins right beyond our cottage near the town of Freeport, Florida, in a forest being created by M.

Davis, a multimillionaire who grew up in a Panhandle trailer and as a young man raised his first stake playing poker. Davis is a tireless, elaborately courteous Southern charmer. But Wilson himself is quick to point out a difference: The longleaf pine forest once covered 90 million acres, or about 60 percent of the land, in a virtually continuous 1,mile stretch across nine states from Virginia to East Texas.

That forest has been reduced by 97 percent, and there are about three million acres of it left. But for the past decade he has been spending half a million dollars a year planting longleaf pine trees and another half million on other parts of a longleaf forest.

Davis remembers his awakening. The next day I gave those ladies enough money to keep going for another two years, which I think scared them, it was so out of the blue.

Then I asked them for a book environmental reading list for me, for my education. Then I started buying up land to see what I could do. An adult male black bear roams across perhaps a hundred square miles of land.

North Florida already had some good-sized clusters of publicly owned longleaf—national forests, state forests, wildlife management areas and, in the western Panhandle, Eglin Air Force Base, a huge facility that back before World War II had itself been a national forest. The problem was that 70 miles separated the first two protected longleaf forests—and it was another 95 miles to the third.

Without any human intervention, here is a forest with tall, straight trees that are rather widely spaced, plenty of sunlight and lots of open, grassy meadows.Essays in Natural History and Evolution: THE ESSAY in science is an art form as well as a means of communicating ideas.

Further evidence for this is argued from the study of island biogeography. For example, of the 1, known species of fruit flies (Drosophila), nearly one third of them live only on the Hawaiian Islands. These islands are also home to more than 1, species of snails and .

Short Exam Study Guides for Biogeography. Island Biogeography W hy do many more species of birds occur on the island of New Guinea than on the island of Bali? One answer is that New Guinea has more than fifty times the area of Bali, and numbers of species ordinarily increase with available space.

Tikopia is a small high island in the southwestern Pacific is part of the Solomon Islands of Melanesia, but is culturally first Europeans arrived on 22 April as part of the Spanish expedition of Pedro Fernandes de Queirós.

Definition of Primary Succession. Primary succession is the colonization of new sites by communities of organisms. It often occurs after a devastating event has wiped out the organisms that lived.

8 Biogeography Essay Questions 1.) What is the science of biogeography? The second biogeographical theory, island biogeography asserts that those pockets of life (islands) that are closely spaced will support more biological life/species.

It is still this second theory that explains that these closely spaced islands are rarely threatened by.
