Microcarbo Serventyorum
'' Microcarbo serventyorum'', also referred to as Serventys' cormorant, is an extinct species of small cormorant from the Holocene of Australia. It was described by Gerard Frederick van Tets from subfossil skeletal material (a pelvis with proximal parts of the femora and some caudal vertebrae) found in 1970 in a peat swamp at Bullsbrook, Western Australia. The pelvic features indicate that the bird was adept at foraging in confined wetlands such as swamps with dense vegetation, small pools and narrow streams. The specific epithet honours the brothers Dominic Dominic is a name common among Roman Catholics and other Latin-Romans as a male given name. Originally from the late Roman-Italic name "Dominicus", its translation means "Lordly", "Belonging to God" or "of the Master". Variations include: Domini ... and Vincent Serventy for their contributions to knowledge of Australian cormorants. References serventyorum Endemic birds of Western Australia Holocene extinc ...

Gerard Frederick Van Tets
Gerard Frederick van Tets (19 January 1929 – 14 January 1995), otherwise known as Jerry van Tets, was a twentieth century British, Canadian and Australian ornithologist and palaeontologist. Born to Dutch parents, jhr. Hendrik Barthout van Tets, heer van Goidschalxoord and Thérèse van Heukelom, in London on 19 January 1929, Van Tets spent his childhood in the Netherlands. Following World War II, he moved to England to complete his schooling at Hazelmere. He completed two years of national service with the Royal Engineers in England and Austria before emigrating to Canada where he studied at the University of Toronto The University of Toronto (UToronto or U of T) is a public university, public research university in Toronto, Ontario, Canada, located on the grounds that surround Queen's Park (Toronto), Queen's Park.

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inu ...

Extinct Birds Of Australia
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holocene Extinctions
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Western Australia
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are Indigenous (ecology), indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus, Cytisus aeolicus'' is an endemite of the Italian flora. ''Enidae, Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a Invasive species, non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a specie ...

Microcarbo
''Microcarbo'' is a genus of fish-eating birds, known as cormorants, of the family Phalacrocoracidae. The genus was formerly subsumed within '' Phalacrocorax''. ''Microcarbo'' has been recognized as a valid genus by the IOC's World Bird List on the basis of work by Siegel-Causey (1988), Kennedy et al. (2000), and Christidis and Boles (2008). As suggested by the name, this genus contains the smallest of the world's cormorants. It is also the most basal, having diverged from the rest of the family between 12.8 to 15.4 million years ago. Taxonomy The genus ''Microcarbo'' was introduced in 1856 by the French naturalist Charles Lucien Bonaparte with the pygmy cormorant as the type species. The name combines the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic p ... ''mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
