White-nose Syndrome
White-nose syndrome (WNS) is a fungal disease in North American bats which has resulted in the dramatic decrease of the bat population in the United States and Canada, reportedly killing millions as of 2018. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats. It was first identified from a February 2006 photo taken in a cave located in Schoharie County, New York. The syndrome has rapidly spread since then. In early 2018, it was identified in 33 U.S. states and seven Canadian provinces; plus the fungus, albeit sans syndrome, had been found in three additional states. Most cases are in the eastern half of both countries, but in March 2016, it was confirmed in a little brown bat in Washington state. In 2019, evidence of the fungus was detected in California for the first time, although no affected bats were found. The disease is caused by the fungus ''Pseudogymnoascus destructans'', which colonizes the bat's skin. No obvious ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudogymnoascus Destructans
''Pseudogymnoascus destructans'' (formerly known as ''Geomyces destructans'') is a psychrophilic (cold-loving) fungus that causes white-nose syndrome (WNS), a fatal disease that has devastated bat populations in parts of the United States and Canada. Unlike species of '' Geomyces'', ''P. destructans'' forms asymmetrically curved conidia. ''Pseudogymnoascus destructans'' grows very slowly on artificial media and cannot grow at temperatures above 20 °C. It can grow around 4 °C to 20 °C, which encompasses the temperatures found in winter bat hibernacula. Phylogenic evaluation has revealed this organism should be reclassified under the family ''Pseudeurotiaceae'', changing its name to ''Pseudogymnoascus destructans''. History In 2008, Blehert ''et al.'' described the fungus associated with white-nose syndrome as a member of the genus ''Geomyces''. In 2009, Gargas ''et al.'' were the first to describe the fungus as a unique species; the specific name they chose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eptesicus Fuscus Map
''Eptesicus'' is a genus of bats, commonly called house bats or serotine bats, in the family Vespertilionidae. The genus name is likely derived from the Greek words ''ptetikos'' 'able to fly' or ''petomai'' 'house flier', although this is not certain. Species 28 species have been identified within the genus. Of these, 19 are from South America. These species are grouped into two subgenera In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between t ...: ''Eptesicus'' and ''Histiotus''.

Big Brown Bat
The big brown bat (''Eptesicus fuscus'') is a species of vesper bat distributed widely throughout North America, the Caribbean, and the northern portion of South America. It was first described as a species in 1796. Compared to other microbats, the big brown bat is relatively large, weighing and possessing a wingspan of . Big brown bats are insectivorous, consuming a diverse array of insects, particularly night-flying insects, but especially beetles. Some of the beetles it consumes are serious agricultural pests, including cucumber beetles. They are nocturnal, foraging for prey at night and roosting in sheltered areas during the day such as caves, tunnels, tree cavities, and human structures. Their breeding season is in the fall, shortly before their annual hibernation. After hibernation ends in the spring, females form maternity colonies for giving birth to young. Oftentimes only one offspring is produced per litter, though twins are common in the Eastern US. Lifespans of 6 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Science Daily
''Science Daily'' is an American website launched in 1995 that aggregates press releases and publishes lightly edited press releases (a practice called churnalism) about science, similar to Phys.org and EurekAlert!. The site was founded by married couple Dan and Michele Hogan in 1995; Dan Hogan formerly worked in the public affairs department of Jackson Laboratory writing press releases. The site makes money from selling advertisements. As of 2010, the site said that it had grown "from a two-person operation to a full-fledged news business with worldwide contributors". At the time, it was run out of the Hogans' home, had no reporters, and only reprinted press releases. In 2012, Quantcast ranked it at 614 with 2.6 million U.S. visitors.

Decline In Amphibian Populations
Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world. These declines are known as one of the most critical threats to global biodiversity. Recent (2007) research indicates the reemergence of varieties of chytrid fungi may account for a substantial fraction of the overall decline. A more recent (2018) paper published in ''Science'' confirms this. Several secondary causes may be involved, including other diseases, habitat destruction and modification, exploitation, pollution, pesticide use, introduced species, and ultraviolet-B radiation (UV-B). However, many of the causes of amphibian declines are still poorly understood, and the topic is currently a subject of much ongoing research. Calculations based on extinction rates suggest that the current extinction rate of amphibians could be 211 times greater than the background extinction rate and the estimate goes up to 25,0 ...

Chytridiomycosis
Chytridiomycosis ( ) is an infectious disease in amphibians, caused by the chytrid fungi '' Batrachochytrium dendrobatidis'' and '' Batrachochytrium salamandrivorans''. Chytridiomycosis has been linked to dramatic population declines or extinctions of amphibian species in western North America, Central America, South America, eastern Australia, east Africa (Tanzania), and Dominica and Montserrat in the Caribbean. Much of the New World is also at risk of the disease arriving within the coming years. The fungus is capable of causing sporadic deaths in some amphibian populations and 100% mortality in others. No effective measure is known for control of the disease in wild populations. Various clinical signs are seen by individuals affected by the disease. A number of options are possible for controlling this disease-causing fungus, though none has proved to be feasible on a large scale. The disease has been proposed as a contributing factor to a global decline in amphibian popu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Public Radio
National Public Radio (NPR, stylized in all lowercase) is an American privately and state funded nonprofit media organization headquartered in Washington, D.C., with its NPR West headquarters in Culver City, California. It differs from other non-profit membership media organizations such as the Associated Press, in that it was established by an act of Congress. Most of its member stations are owned by non-profit organizations, including public school districts, colleges, and universities. It serves as a national Radio syndication, syndicator to a network of over 1,000 public radio List of NPR stations, stations in the United States. , NPR employed 840 people. NPR produces and distributes news and cultural programming.

All Things Considered
''All Things Considered'' (''ATC'') is the flagship news program on the American network National Public Radio (NPR). It was the first news program on NPR, premiering on May 3, 1971. It is broadcast live on NPR affiliated stations in the United States, and worldwide through several different outlets, formerly including the NPR Berlin station in Germany.
