Petrogale Burbidgei
The rock-wallabies are the wallabies of the genus ''Petrogale''. Taxonomy The genus was established in 1837 by John Edward Gray in a revision of material at the British Museum of Natural History. Gray nominated his earlier description of ''Kangurus pencillatus'' as the type species, now recognised in the combination ''Petrogale penicillata'' (brush-tailed rock-wallaby). The author separated the species from the defunct genus ''Kangurus'', which he proposed to divide in his synopsis of the known macropod species. The following is a list of species, with common names, arranged by alliances of species groups: * Genus ''Petrogale'' ** ''P. brachyotis'' species group *** Short-eared rock-wallaby, ''Petrogale brachyotis'' *** Monjon, ''Petrogale burbidgei'' *** Nabarlek, ''Petrogale concinna'' *** Eastern short-eared rock-wallaby, ''Petrogale wilkinsi'' ** ''P. xanthopus'' species group *** Proserpine rock-wallaby, ''Petrogale persephone'' *** Rothschild's rock-wallaby, ''Petrogale ...

Rothschild's Rock-wallaby
Rothschild's rock-wallaby (''Petrogale rothschildi'') – sometimes known as the Roebourne rock-wallaby, is a species of macropod found in Western Australia, in the Pilbara district and the Dampier Archipelago. It is not currently considered to be threatened, but is at risk from the red fox (''Vulpes vulpes''). Rothschild's rock-wallaby is one of the largest rock-wallabies. It is predominantly golden-brown in colour with a greyish wash down its neck, which often has a purple appearance. It is mainly a nocturnal grass-eater usually found around rocky ground. Taxonomy ''Petrogale rothschildi'' was first described by Oldfield Thomas in 1904, describing a skin provided by J. T. Tunney's collection from the Northwest of Australia. Tunney's specimen was a female's skin, without a skull, collected in July 1901 at Cossack River. Thomas saw an affinity with what was termed the ''Petrogale pencillatus-lateralis'' group, but distinguished enough characteristics to propose a new species ...

Mareeba Rock-wallaby
The Mareeba rock-wallaby (''Petrogale mareeba'') is a rare species of rock-wallaby found around Mareeba in northeastern Queensland, Australia. Taxonomy The Mareeba rock-wallaby is a member of a group of seven very closely related species within the genus '' Petrogale'', which also includes the Cape York rock-wallaby (''P. coenensis''), the unadorned rock-wallaby (''P. inornata'') and the allied rock-wallaby (''P. assimilis''). It was only identified as a separate species in 1992. Both the common name and the Latin specific epithet reflect the distribution of this species around the settlement of Mareeba. Distribution and habitat The Mareeba rock-wallaby is a rare species, found in the highlands west of Cairns from around Mount Garnet to the Mitchell River and Mount Carbine, and inland to Mungana, but only on the tops of a couple of mountain ranges. The animals can be seen in their natural habitat in the Granite Gorge Nature Park, about inland from Cairns. Conservation ...

Goat
The goat or domestic goat (''Capra hircus'') is a species of Caprinae, goat-antelope that is mostly kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the family Bovidae, meaning it is closely related to the sheep. It was one of the first animals to be domesticated, in Iran around 10,000 years ago. Goats have been used for milk, Goat meat, meat, Animal fur, wool, and Animal skin, skins across much of the world. Milk from goats is often turned into goat cheese, cheese. In 2022, there were more than 1.1 billion goats living in the world, of which 150 million were in India. Goats feature in mythology, folklore, and religion in many parts of the world, including in the classical myth of Amalthea (mythology), Amalthea, in Tanngrisnir and Tanngnjóstr, the goats that pulled the chariot of the Norse god Thor, in the Scandinavian Yule goat, and in Hinduism's goat-headed Daksha.

Red Fox
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern on the IUCN Red List. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native small and medium-sized rodents and marsupials. Due to its impact on native species, it is included on the list of the "List of the world's 100 worst invasive species, world's 100 worst invasive species". The red fox originated in Eurasia during the Middle Pleistocene at least 400,000 years ago and later colonised North America sometime prior to 130,000 years ago. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is distin ...

Colony
A colony is a territory subject to a form of foreign rule, which rules the territory and its indigenous peoples separated from the foreign rulers, the colonizer, and their ''metropole'' (or "mother country"). This separated rule was often organized into colonial empires, with their metropoles at their centers, making colonies neither annexation, annexed or even Territorial integration, integrated territories, nor client states. Particularly new imperialism and its colonialism advanced this separated rule and its lasting coloniality. Colonies were most often set up and colonized for exploitation and possibly settlement by colonists. The term colony originates from the ancient rome, ancient Roman , a type of Roman settlement. Derived from ''colonus'' (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'. Furthermore, the term was used to refer to the older Greek ''apoikia'' (), which were Greek colonisation, overseas settlements by ...

Nocturnal
Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing (sense), hearing, olfaction, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbaby, bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsier, tarsiers and some owl, owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cytonuclear Discordance
Cytonuclear (or mito-nuclear) discordance describes the discrepancy in phylogenetic relationships using mitochondrial DNA (mtDNA) versus nuclear genes (or nuclear DNA, nDNA). In other words, mitochondrial and nuclear gene sequences may lead to different, if not contradictory, phylogenetic trees that show the relationships among species 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. It is the basic unit of Taxonomy (biology), .... In theory, nuclear DNA and mtDNA sequences should lead to similar phylogenetic tree topologies among species but this is often not the case. Other terms for the concept are ''Nuclear-mitochondrial discordance'' or ''mito-nuclear discordance''. Examples An example are Australian rock-wallabies (''Petrogale'') in which several species form a monophyletic group with nDNA genes, but not with mtDNA. Thi ...

Phylogenetic Tree
A phylogenetic tree or phylogeny is a graphical representation which shows the evolutionary history between a set of species or taxa during a specific time.Felsenstein J. (2004). ''Inferring Phylogenies'' Sinauer Associates: Sunderland, MA. In other words, it is a branching diagram or a tree showing the evolutionary relationships among various biological species or other entities based upon similarities and differences in their physical or genetic characteristics. In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry. Phylogenetics is the study of phylogenetic trees. The main challenge is to find a phylogenetic tree representing optimal evolutionary ancestry between a set of species or taxa. Computational phylogenetics (also phylogeny inference) focuses on the algorithms involved in finding optimal phylogenetic tree in the phylogenetic landscape. Phylogenetic trees may be rooted or unrooted. In a ''rooted'' p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It als ...
