Experts had suspected that an invasive species was to blame for the die-off from "white nose syndrome. The fungal illness has not caused widespread deaths among European bats unlike in the U.
More than 1, species of bats around the world are playing ecological roles that are vital to the health of natural ecosystems and human economies. Many of the more than 1, bat species consume vast amounts of insects, including some of the most damaging agricultural pests. Others pollinate many valuable plants, ensuring the production of fruits that support local economies, as well as diverse animal populations.
Fruit-eating bats in the tropics disperse seeds that are critical to restoring cleared or damaged rainforests.
Even bat droppings called guano are valuable as a rich natural fertilizer. Guano is a major natural resource worldwide, and, when mined responsibly with bats in mind, it can provide significant economic benefits for landowners and local communities.
Consider the great baobab tree of the East African savannah. Pest control Insectivorous bats are primary predators of night-flying insects, and many very damaging pests are on their menu. Pregnant or nursing mothers of some bat species will consume up to their body weight in insects each night.
And a favorite target in the United States and Mexico is an especially damaging pest called the corn earworm moth aka cotton bollworm, tomato fruitworm, etc.
And that, of course, means fewer pesticides enter the ecosystem.
White nose syndrome has killed bats in four Canadian provinces and 19 U.S. states, mostly in the Northeast and South. Last week, the illness marched west of the Mississippi River, infecting bats. White-nose Syndrome in Bats White-nose syndrome, (Geomyces destructions), is a fungus that attacks the bats’ exposed skin and flight membranes, causing them to suffocate or starve. White-nose syndrome (WNS), first discovered in , has now spread to 20 states and has led to the deaths of over million bats (as of January ). WNS is a disease caused by the fungus, Pseudogymnoascus destructans.
In North American deserts, giant cacti and agave depend on bats for pollination, while tropical bats pollinate incredible numbers of plants.
Most flowering plants cannot produce seeds and fruit without pollination — the process of moving pollen grains from the male part of the flower the stamen to the female part the pistil. This process also improves the genetic diversity of cross-pollinated plants. Bats that drink the sweet nectar inside flowers pick up a dusting of pollen and move it along to other flowers as they feed.
A few of the commercial products that depend on bat pollinators for wild or cultivated varieties include: And fruit-eating bats are key players in restoring those vital forests.
But birds are wary of crossing large, open spaces where flying predators can attack, so they typically drop seeds directly beneath their perches.
Night-foraging fruit bats, on the other hand, often cover large distances each night, and they are quite willing to cross clearings and typically defecate in flight, scattering far more seeds than birds across cleared areas. And many of the bat-dispersed seeds are from hardy pioneer plants, the first to grow in the hot, dry conditions of clearings.
As these plants grow, they provide the shelter that lets other, more delicate plants take root. Seeds dropped by bats can account for up to 95 percent of the first new growth. The pioneer plants also offer cover and perches for birds and primates, so they can add still more, different seeds to the mix that can lead eventually to a renewed forest.
Bats have been reported dispersing the seeds of avocado, dates, figs, and cashews - among many others.Case Study "No Bats in the Belfry: The origin of White-Nose Syndrome in Little Brown Bats" Words | 3 Pages Biology Lab Case Study "No Bats in the Belfry: The origin of White-Nose Syndrome in Little Brown Bats" Part 1 Questions 1.

Early evidence suggests that another fungal pathogen, Geomyces destructans, introduced from Europe is responsible for white-nose syndrome, which infects cave-hibernating bats in eastern North America and has spread from a point of origin in western New York State ().
White-nose syndrome: A Yuma myotis and either a little brown bat or Yuma myotis (species was not genetically identified) were found on separate occasions near North Bend in King County.
Both bats were dead when a biologist collected them and showed signs of white-nose syndrome. Essay about White Nose Syndrome in Bats - The population of bats in the United States is facing a serious threat of extinction due to the outbreak of a deadly fungus called Deomyces destructans. The fungus is nicknamed White-Nose Syndrome, after the white fungus that typically appears on the infected bats noses and wings.
The following species have been infected by white-nose syndrome: little brown bat (once the most common bat in the eastern United States), northern long-eared bat (threatened), tricolored bat, Indiana bat (endangered), the big brown bat, eastern small-footed bat, and gray bat (endangered).
