Lee Berger (biologist)
Lee Berger (born 16 January 1970), is an Australian biologist and veterinarian, who discovered during her PhD that the fungus '' Batrachochytrium dendrobatidis'' was responsible for the decline and extinction of hundreds of amphibian species. Early life and career Berger was born in Epsom, England in 1970, but moved to Melbourne, Australia with her family just a year later. She earned her undergraduate degree in Veterinary Science from the University of Melbourne. She was awarded her PhD at James Cook University in 2001 under the supervision of Rick Speare Richard "Rick" Speare (2 August 1947 – 5 June 2016) was an Australian public health physician and veterinary surgeon. He is best known for his research on animal diseases, particularly his work on chytridiomycosis in amphibians. Research caree .... In her PhD she aimed to find the cause of the decline of amphibians in Queensland between the 1970s and 1990s. She identified the cause as being a chytrid fungus, '' Ba ...

University Of Melbourne
The University of Melbourne is a public research university located in Melbourne, Australia. Founded in 1853, it is Australia's second oldest university and the oldest in Victoria. Its main campus is located in Parkville, an inner suburb north of Melbourne's central business district, with several other campuses located across Victoria. Incorporated in the 19th century by the colony of Victoria, the University of Melbourne is one of Australia's six sandstone universities and a member of the Group of Eight, Universitas 21, Washington University's McDonnell International Scholars Academy, and the Association of Pacific Rim Universities. Since 1872, many residential colleges have become affiliated with the university, providing accommodation for students and faculty, and academic, sporting and cultural programs. There are ten colleges located on the main campus and in nearby suburbs. The university comprises ten separate academic units and is associated with numerous institut ...

Epsom, England
Epsom is the principal town of the Borough of Epsom and Ewell in Surrey, England, about south of central London. The town is first recorded as ''Ebesham'' in the 10th century and its name probably derives from that of a Saxon landowner. The earliest evidence of human activity is from the mid-Bronze Age, but the modern settlement probably grew up in the area surrounding St Martin's Church in the 6th or 7th centuries and the street pattern is thought to have become established in the Middle Ages. Today the High Street is dominated by the clock tower, which was erected in 1847–8. Like other nearby settlements, Epsom is located on the spring line where the permeable chalk of the North Downs meets the impermeable London Clay. Several tributaries of the Hogsmill River rise in the town and in the 17th and early 18th centuries, the spring on Epsom Common was believed to have healing qualities. The mineral waters were found to be rich in ''Epsom salts'', which were later identifie ...

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 populat ...

Chytrid Fungus
Chytridiomycota are a division of zoosporic organisms in the kingdom Fungi, informally known as chytrids. The name is derived from the Ancient Greek ('), meaning "little pot", describing the structure containing unreleased zoöspores. Chytrids are one of the early diverging fungal lineages, and their membership in kingdom Fungi is demonstrated with chitin cell walls, a posterior whiplash flagellum, absorptive nutrition, use of glycogen as an energy storage compound, and synthesis of lysine by the -amino adipic acid (AAA) pathway. Chytrids are saprobic, degrading refractory materials such as chitin and keratin, and sometimes act as parasites. There has been a significant increase in the research of chytrids since the discovery of ''Batrachochytrium dendrobatidis'', the causal agent of chytridiomycosis. Classification Species of Chytridiomycota have traditionally been delineated and classified based on development, morphology, substrate, and method of zoöspore discharge. Howeve ...

Melbourne, Australia
Melbourne ( ; Boonwurrung/Woiwurrung: ''Narrm'' or ''Naarm'') is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in both Australia and Oceania. Its name generally refers to a metropolitan area known as Greater Melbourne, comprising an urban agglomeration of 31 local municipalities, although the name is also used specifically for the local municipality of City of Melbourne based around its central business area. The metropolis occupies much of the northern and eastern coastlines of Port Phillip Bay and spreads into the Mornington Peninsula, part of West Gippsland, as well as the hinterlands towards the Yarra Valley, the Dandenong and Macedon Ranges. It has a population over 5 million (19% of the population of Australia, as per 2021 census), mostly residing to the east side of the city centre, and its inhabitants are commonly referred to as "Melburnians". The area of Melbourne has been home to Aboriginal Victorians ...

Batrachochytrium Dendrobatidis
''Batrachochytrium dendrobatidis'' ( ), also known as ''Bd'' or the amphibian chytrid fungus, is a fungus that causes the disease chytridiomycosis in amphibians. Since its discovery in 1998 by Lee Berger, the disease devastated amphibian populations around the world, in a global decline towards multiple extinctions, part of the Holocene extinction. A recently described second species, '' B. salamandrivorans'', also cause chytridiomycosis and death in salamanders. The fungal pathogens that cause the disease chytridiomycosis ravage the skin of frogs, toads, and other amphibians, throwing off their balance of water and salt and eventually causing heart failure, Nature reports. Some amphibian species appear to have an innate capacity to withstand chytridiomycosis infection due to symbiosis with ''Janthinobacterium lividum''. Even within species that generally succumb, some populations survive, possibly demonstrating that these traits or alleles of species are being subjected to evo ...
