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 ...

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 hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

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 sig ... [...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 ...

Bullsbrook, Western Australia
Bullsbrook (formerly Bullsbrook East) is a northern suburb of Perth, Western Australia in the outer metropolitan area. It is located in the City of Swan. The original Bullsbrook townsite is located slightly west of the current town, on the 17 km mark of the Midland Railway. Bullsbrook is also home to the RAAF Pearce airbase, a major training facility for the Royal Australian Air Force. The suburb is situated on the Great Northern Highway, 25 kilometres north of the Midland Strategic Regional Centre. It is well serviced by several major transport networks including the Great Northern Highway, Railway Parade and the Brand Highway to the north, Chittering Road to the east and Neaves Road to the west. Bullsbrook is also adjacent to the State rail network, providing an opportunity for the development of an intermodal freight transport hub. The site is further strengthened by linkage to the planned Perth-Darwin National Highway via Stock Road. Although traditionally a predominantl ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Caudal Vertebrae
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
