Gulf Snapping Turtle
The Gulf snapping turtle or Lavaracks' turtle (''Elseya lavarackorum'') is a large species of freshwater turtle in the sidenecked family Chelidae.Georges A, Thomson S (2010)"Diversity of Australasian freshwater turtles, with an annotated synonymy and keys to species".''Zootaxa'' 2496: 1–37. The species is endemic to northern Australia in northwest Queensland and northeast Northern Territory. The species, similar to other members of the Australian snapping turtles in genus ''Elseya,'' only comes ashore to lay eggs and bask.Cann J (1998). ''Australian Freshwater Turtles''. Singapore: Beaumont. 292 pp. . The Gulf snapping turtle is a herbivore and primarily consumes '' Pandanus'' and figs. Etymology The specific name, ''lavarackorum'' (genitive plural), is in honor of Australian paleontologists Jim Lavarack and Sue Lavarack who discovered the fossil remains of this species.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).

Calvert River
The Calvert River is a river in the Northern Territory of Australia. Course The headwaters rise on a plain between the Calvert Hills and China Wall and flow northward through mostly uninhabited lands and pastoral leases such as Calvert Hills Station before finally discharging into the Gulf of Carpentaria east of Borroloola, not far from the border with Queensland in the Gulf Coastal bioregion. It has a mean annual outflow of , Before reaching the sea it flows through the Australian Wildlife Conservancy’s Pungalina-Seven Emu Sanctuary. Fourteen tributaries feed the river including; Bloodwood Creek, Tobacco Creek, Goanna Creek, Pungalina Creek and the Little Calvert River. Catchment The river’s catchment area is , wedged between the watersheds for the Robinson River to the west, Settlement Creek to east and the Nicholson River to the south. It contains no major towns and the population was 103 in 2001, 45% of whom are Aboriginal people. The river is not dammed, nor ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelonian Conservation And Biology
''Chelonian Conservation and Biology: International Journal of Turtle and Tortoise Research'' is a peer-reviewed scientific journal covering research on freshwater turtles, marine turtles, and tortoises ( Order Testudines). It was established in 1993 by the Chelonian Research Foundation as the new scientific journal of the IUCN Species Survival Commission's Tortoise and Freshwater Turtle Specialist Group and the ''International Bulletin of Chelonian Research''. The journal was first published with support from Conservation International, the Chelonian Institute, the Wildlife Conservation Society, the Florida Audubon Society, and the Species Survival Commission of the World Conservation Union. Since 2006, the journal has been published in collaboration with Allen Press Publishing Services.

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbivory
A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. As a result of their plant diet, herbivorous animals typically have mouthparts adapted to rasping or grinding. Horses and other herbivores have wide flat teeth that are adapted to grinding grass, tree bark, and other tough plant material. A large percentage of herbivores have mutualistic gut flora that help them digest plant matter, which is more difficult to digest than animal prey. This flora is made up of cellulose-digesting protozoans or bacteria. Etymology Herbivore is the anglicized form of a modern Latin coinage, ''herbivora'', cited in Charles Lyell's 1830 ''Principles of Geology''.J.A. Simpson and E.S.C. Weiner, eds. (2000) ''The Oxford English Dictionary'', vol. 8, p. 155. Richard Owen employed the anglicized term in an 1854 work on fossil teeth and skeletons. ''Herbivora'' is derived from Latin ''herba' ...

Nicholson River (Western Australia)
The Nicholson River is a river in the Kimberley region of Western Australia. It takes its name from the Nicholson Plains, named in 1879 by Alexander Forrest after Sir Charles Nicholson, the central figure in the circle of Australian 'colonists' in London, and a promoter of the Forrest brothers' explorations. In 1870 Nicholson had presented a paper entitled ''On Forrest's Expedition into the Interior of Western Australia, Goyder's Survey of the Neighbourhood of Port Darwin, and on the Recent Progress of Australian Discovery'' to a meeting of the Royal Geographical Society of London. The river rises just north of Koolerong Bore then flows south-west through Nicholson and through Marella Gorge then turning north and discharging into the Ord River on the eastern edge of Purnululu National Park near Doughboy Hill. There are eleven tributaries A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary d ...

Gulf Of Carpentaria
The Gulf of Carpentaria (, ) is a large, shallow sea enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea (the body of water that lies between Australia and New Guinea). The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land) in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between and does not exceed . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Annals and Magazine of Natural History''. 3(12):98-99 the northern snapping turtle, is a large aquatic turtle found throughout many rivers in northern Western Australia and the Northern Territory. It is one of three species in the nominate subgenus ''Elseya''. Etymology This species is named for the serrated margin of the shell, mostly only visible in younger animals. Taxonomy During their revision of the New Guinea ''Elseya'' a lectotype was set for this species. Further it was placed in a subgenus 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 ... and as the type species of the genus it is therefore in the nominate subgenus.Thomson, S., Amepou, ...

Suture (anatomy)
In anatomy, a suture is a fairly rigid joint between two or more hard elements of an organism, with or without significant overlap of the elements. Sutures are found in the skeletons or exoskeletons of a wide range of animals, in both invertebrates and vertebrates. Sutures are found in animals with hard parts from the Cambrian period to the present day. Sutures were and are formed by several different methods, and they exist between hard parts that are made from several different materials. Vertebrate skeletons The skeletons of vertebrate animals (fish, amphibians, reptiles, birds, and mammals) are made of bone, in which the main rigid ingredient is calcium phosphate. Cranial sutures The skulls of most vertebrates consist of sets of bony plates held together by cranial sutures. These sutures are held together mainly by Sharpey's fibers which grow from each bone into the adjoining one. Sutures in the ankles of land vertebrates In the type of crurotarsal ankle which is fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carapace
A carapace is a dorsal (upper) section of the exoskeleton or shell in a number of animal groups, including arthropods, such as crustaceans and arachnids, as well as vertebrates, such as turtles and tortoises. In turtles and tortoises, the underside is called the plastron. Crustaceans In crustaceans, the carapace functions as a protective cover over the cephalothorax (i.e., the fused head and thorax, as distinct from the abdomen behind). Where it projects forward beyond the eyes, this projection is called a rostrum. The carapace is calcified to varying degrees in different crustaceans. Zooplankton within the phylum Crustacea also have a carapace. These include Cladocera, ostracods, and isopods, but isopods only have a developed "cephalic shield" carapace covering the head. Arachnids In arachnids, the carapace is formed by the fusion of prosomal tergites into a single plate which carries the eyes, ocularium, ozopores (a pair of openings of the scent gland of Opiliones) a ...

Combinatio Nova
''Combinatio nova'', abbreviated ''comb. nov.'' (sometimes ''n. comb.''), is Latin for "new combination". It is used in taxonomic biology literature when a new name is introduced based on a pre-existing name. The term should not to be confused with ', used for a previously unnamed species. There are three situations: * the taxon is moved to a different genus * an infraspecific taxon is moved to a different species * the rank of the taxon is changed. Examples When an earlier named species is assigned to a different genus, the new genus name is combined with of said species, e.g. when ''Calymmatobacterium granulomatis'' was renamed '' Klebsiella granulomatis'', it was referred to as ''Klebsiella granulomatis comb. nov.'' to denote it was a new combination.
