Delma Vescolineata
''Delma vescolineata'', commonly known as the Hunter Valley Delma, is a species of legless gecko from the Pygopodidae family. Taxonomy Discovered in 2012, the species is endemic to the Hunter Valley and Liverpool Plains region of New South Wales, Australia, but was believed to be either a separated population of Striped legless lizard (''Delma impar''), or part of the local population of Leaden Delma (''Delma plebeia''). DNA analyses in 2022 confirmed its status as a sister species of the Striped legless lizard. The Hunter Valley Delma can be further differentiated from the Striped legless lizard due to its barred lips, weaker stripes and subtle differences in scale and head shape. Distribution and habitat ''Delma vescolineata'' is the only species of ''Delma'' entirely endemic to New South Wales New South Wales (commonly abbreviated as NSW) is a States and territories of Australia, state on the Eastern states of Australia, east coast of :Australia.

Legless Lizard
Legless lizard may refer to any of several groups of lizards that have independently lost limbs or reduced them to the point of being of no use in locomotion.Pough ''et al.'' 1992. Herpetology: Third Edition. Pearson Prentice Hall:Pearson Education, Inc., 2002. It is the common name for the family Pygopodidae. These lizards are often distinguishable from snakes on the basis of one or more of the following characteristics: *possessing eyelids *possessing Outer ear, external ear openings *lack of broad belly scales *notched rather than forked tongue, forked tongue *having two lungs of roughly equal size (snakes have one short and one very long lung) *having a very long tail (while snakes have a long body and short tail). Every stage of reduction of the Shoulder girdle#Other animals, shoulder girdle —including complete loss— occurs among limbless Squamata, squamates, but the Hip bone#Evolution of the pelvis in animal, pelvic girdle is never completely lost regardless of the degr ...

Pygopodidae
Pygopodidae, commonly known as snake-lizards, or flap-footed lizards, are a Family (biology), family of Legless lizard, legless lizards with reduced or absent limbs, and are a type of gecko. The 47 species are placed in two subfamilies and eight Genus, genera. They have unusually long, slender bodies, giving them a strong resemblance to snakes. Like snakes and most geckos, they have no eyelids, but unlike snakes, they have external ear holes and flat, unforked tongues. They are native to Australia and New Guinea. Pygopodids have no fore limbs at all, but they do possess vestigial hind limbs in the form of small, flattened flaps. These may have some role in courtship and defensive behaviour, and may even aid in locomotion through vegetation. Some species are insectivore, insectivorous burrowing animals, but others are adapted to moving through dense Triodia (grass), spinifex or other vegetation. Shared gecko characteristics The pygopodids and other geckos share a number of charact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Hunter Region
The Hunter Region, also commonly known as the Hunter Valley, Newcastle Region, or simply Hunter, spans the region in northern New South Wales, Australia, extending from approximately to north of Sydney. It contains the Hunter River (New South Wales), Hunter River and its tributaries with highland areas to the north and south. Situated at the northern end of the Sydney Basin bioregion, the Hunter Valley is one of the largest river valleys on the NSW coast, and is most commonly known for its wineries and coal industry. Most of the population of the Hunter Region lives within of the coast, with 55% of the entire population living in the cities of Newcastle, New South Wales, Newcastle and City of Lake Macquarie, Lake Macquarie. There are numerous other towns and villages scattered across the region in the eleven Local government in Australia, local government areas (LGAs) that make up the region. At the the combined population of the region was 682,465, and is expected to reach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool Plains
The Liverpool Plains are an extensive agricultural area covering about of the north-western slopes of New South Wales in Australia. These plains are a region of prime agricultural land bounded to the east by the Great Dividing Range, to the south by the Liverpool Range and on the west by the Warrumbungle Range. The area is drained by the Namoi River and its tributaries, the Mooki River and the Peel River. There are many depressions, across the plains, which remain as lakes for long periods after heavy rain. These plains are unusual in that many steep hills arise suddenly from the plains. Towns in the Liverpool Plains include Gunnedah, Narrabri, Quirindi, Werris Creek and Tamworth. Smaller villages include Breeza, Carroll, Mullaley and Willow Tree. Most of the region nowadays comes under the jurisdiction of Liverpool Plains Shire Council. However substantial parts of the region also form part of the Gunnedah and Tamworth local government areas. History The Liv ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...
