Amphibians (a group that includes salamanders, frogs, toads, and caecilians [wormlike amphibians]), being particularly sensitive to environmental changes, are severely threatened by habitat destruction, pollution, the spread of a disease called amphibian chytridiomycosis, and climate change. Primary succession can occur, for example, following the eruption of volcanoes such as those on Hawaii's Big Island. The disease is named for the white fungus Geomyces destructans that infects the skin of the muzzle, ears, and wings of hibernating bats.

These eggs were usually crushed before they could hatch. They are called: Which of the following is a type of biodiversity described in the textbook? Some species do really well after a disturbance. Mouse populations are mostly tracked over 10-year periods. An area of occupancy is where a specific population of that species resides. One thing we do know: The western black rhinoceros, the Tasmanian tiger, and the woolly mammoth are among the creatures whose populations at one point dwindled to zero, and it's possible that. People are clearing forests to create cattle pastures. Almost all potatoes cultivated, sold, and consumed, for instance, are from a single species, the Russet Burbank.

Ebony is an endangered species because many biologists calculate its probability of extinction in the wild is at least 20 percent within five generations.Ebony is threatened due to overharvesting. This pathogen has the potential to worsen already severe worldwide amphibian declines. Many wild animals, such as pigeons and houseflies, are also classified as least concern.Near ThreatenedA near threatened species is one that is likely to qualify for a threatened category in the near future.Many species of violets, native to tropical jungles in South America and Africa, are near threatened, for instance. To finance a new product line, a company that makes high-temperature ball bearings borrowed $1.8 million at 10% per year interest. Loss of Genetic VariationGenetic variation is the diversity found within a species. These healthy populations usually occupy protected habitats such as the Hanford Reach on the Columbia River and streams of Olympic National Park.
