Litoria Nyakalensis
The mountain mist frog or Nyakala frog (''Ranoidea nyakalensis'') was a species of frog in the subfamily Pelodryadinae, Endemism, endemic to Australia. Its natural habitats were subtropical or tropical moist lowland forests and rivers. It was threatened by habitat loss and potentially chytrid fungus, before being declared extinct in 2022. Taxonomy The mountain mist frog was one of the four species of Australian torrent treefrogs that comprise the ''Ranoidea nannotis'' species group. The other species are the common mist frog, waterfall frog, and armoured mist frog.

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfall Frog
The Australian waterfall frog or torrent treefrog (''Ranoidea nannotis'') is a species of tree frog native to Far North Queensland, Australia. The common name "waterfall frog" is indicative of its habitat of moist, rocky streams, and is often found along waterfalls within its range. Taxonomy The waterfall frog is one of the four species of Australian torrent treefrogs that comprise the '' Ranoidea nannotis'' species group. The other species are the mountain mist frog, common mist frog, and the armoured mist frog. Description The waterfall frog is large in size, reaching 5.5 cm in length. The dorsal surface is mottled with puck brown. The patterning on the back is similar to its habitat, allowing for effective camouflage against granite. The ventral surface is bright orange, green, and pink in colour, and granular. The posterior ventral surface is translucent, showing internal parts. The toe pads of ''R. nannotis'' are very large in comparison to toe width, to aid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 1974
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Nature Conservation Act Endangered Biota
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...

Ranoidea (genus)
''Ranoidea'' is a genus of frogs in the subfamily Pelodryadinae. They are found in Australia, New Guinea, and two nearby groups of islands: the Maluku Islands, and the Louisiade Archipelago. The circumscription of this taxon is still controversial. Taxonomy Species in this genus were until recently placed in the then-paraphyletic genus ''Litoria''; many of them had been placed in even larger ''Hyla'' before. However, in 2016 Duellman and colleagues split ''Litoria'' into several genera. The systematic and taxonomic conclusions based on Duellman ''et al.'' should be treated with caution, because 78.9% of individuals (397/503) used in the concatenated analyses had less than half of the gene sequences available for the 19 genes used. Missing data can be problematic in phylogenetic analyses (e.g.) and lead to erroneous conclusions about systematic relationships. Additionally, there is no mention of checking for base-composition bias amongst taxa (non-stationarity), which can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armoured Mist Frog
The armoured frog (''Ranoidea lorica''), or armoured mist frog, is a species of tree frog in the torrent frog complex, a group restricted to north-eastern Queensland, Australia. Taxonomy The armoured mist frog is one of the four species of Australian torrent treefrogs that comprise the ''Ranoidea nannotis'' species group. The other species are the mountain mist frog, waterfall frog, and common mist frog. Description ''R. lorica'' is a small tree frog, growing up to in length. It is grey or grey-brown on the dorsal surface and white on the ventral surface. The skin is tubercular on the dorsal surface, prominently on the eyelids and around the tympanum. Fingers are half webbed and toes are fully webbed, both having well-developed discs. The tympanum is small and indistinct, and a vocal sac is not present. Males have black, spiny nuptial pads on their thumbs and "accessory spines" on their chests. These spines are used in amplexus by the males to attain a better grip on t ...

Common Mist Frog
The common mist frog (''Ranoidea rheocola'') is a species of tree frog native to north-eastern Queensland, Australia. It is a medium-sized frog and a member of the Australian torrent treefrog group.Cunningham, M. (n.d.). Memoirs of the Queensland Museum – Nature. https://doi.org/10.17082/j.2204-1478 The common mist frog is found in remote, mountainous areas, and near rocky, fast-flowing rainforest streams such as those in north-eastern Queensland, Australia. They are generally sedentary frogs, and remain in the stream environments that they are born into, preferring sections of the stream with riffles, many rocks, and overhanging vegetation.Lee K Curtis, Keith R McDonald, Andrew J Dennis, Peter M Kyne, & Stephen JS Debus.

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...
