Pearson's Green Tree Frog
Pearson's green tree frog (''Ranoidea pearsoniana''), also known as the Cascade tree frog, is a species of tree frog inhabiting rainforest creeks from north of Lismore, New South Wales, to Kenilworth, Queensland, with a disjunct population at Kroombit Tops Queensland, Australia. Taxonomy The mountain stream tree frog may be conspecific to Pearson's green tree frog. Morphological differences have not been fully studied yet, but visible physical differences between frogs from Barrington Tops and Dorrigo, New South Wales, in comparison to frogs from south-eastern Queensland and northern New South Wales are discussed in a key on the leaf green tree frog page. These are representative of frogs described as ''R. barringtonensis'' and ''R. pearsoniana''. Description Pearson's tree frog is a small tree frog growing up to 45 mm in length. Its dorsal surface can range from completely light green, to a mixture of green and brown, or mostly brown in colour. Usually, black dots are sca ...

Tree Frog
A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to treefrogs, although they are not closely related to each other. Millions of years of convergent evolution have resulted in very similar morphology even in species that are not very closely related. Furthermore, tree frogs in seasonally arid environments have adapted an extra-epidermal layer of lipid and mucus as an evolutionary convergent response to accommodate the periodic dehydration stress. Description As the name implies, these frogs are typically found in trees or other high-growing vegetation. They do not normally descend to the ground, except to mate and spawn, though some build foam nests on leaves and rarely leave the trees at all as adults. Tree frogs are usually tiny as their weight has to be carried by the branches and twigs in their habitats. While some reach 10 ...

Litoria Pearsoniana 2
''Litoria'' is a genus of hylid tree frogs, sometimes collectively referred to as Australasian treefrogs, that are native to Australia, the Bismarck Archipelago, the Solomon Islands, New Guinea, the Lesser Sunda Islands, and the Moluccan Islands. They are distinguishable from other tree frogs by the presence of horizontal irises, no pigmentation of the eyelids, and their distribution east and south from Wallacea. Over one hundred species are recognised and new species are still being added, such as the Pinocchio frog discovered in 2008 and described in 2019. The species within the genus ''Litoria'' are extremely variable in appearance, behaviour, and habitat. The smallest species is the javelin frog (''L. microbelos''), reaching a maximum snout–to–vent length of , while the largest, the giant tree frog (''L. infrafrenata''), reaches a size of . The appearance, behaviour, and habitat of each frog is usually linked. The small, darkly coloured frogs are generally terrestrial, a ...

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 ...

Amphibians Of New South Wales
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 decline ...

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] |
Nature Conservation Act 1992
The ''Nature Conservation Act 1992'' is an act of the Parliament of Queensland, Australia, that, together with subordinate legislation, provides for the legislative protection of Queensland's threatened biota. As originally published, it provided for biota to be declared ''presumed extinct'', ''endangered'', ''vulnerable'', ''rare'' or ''common''. In 2004 the act was amended to more closely align with the IUCN Red List categories: ''presumed extinct'' was changed to ''extinct in the wild'' and ''common'' was changed to ''least concern''. ''Near threatened'' was introduced as an eventual replacement for ''rare'', but the latter was to be phased out over time rather than immediately abandoned. The act is administered by the state's Environmental Protection Agency (EPA). There are provisions under the act which allow landholders to negotiate voluntary conservation agreements with the EPA. New regulations came into effect on 22 August 2020: Text may have been copied from this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
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 provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Leaf Green Tree Frog
The southern leaf green tree frog (''Ranoidea nudidigitus'') is a species of tree frog native to coastal areas and the ranges of south-eastern Australia. It is distributed from just south of Sydney to eastern Victoria. Description ''Ranoidea nudidigitus'' is a small species of tree frog, up to about in length. Adults are normally green on their dorsal surfaces (although at times they can be brown), but metamorph frogs are always dull brown in colour. They are very similar to the leaf green tree frog (''Ranoidea phyllochroa''), and distribution and call are used to distinguish the two. The tympanum is indistinct (it is distinct in ''R. phyllochroa''). A black stripe on the side of the head starts at the nostril and continues down the side of the frog; it often gets larger the further down the frog it goes. A gold stripe occurs above the black one and follows it in the same direction. Ecology and behaviour This species has only recently been separated from the leaf green tree fro ...

Leaf Green Tree Frog
The leaf green tree frog (''Ranoidea phyllochroa'') is a species of stream-dwelling frog, native to eastern Australia from the Queensland/New South Wales border south to Sydney. Description This is a fairly small species of tree frog, up to about in length. It can be light green to dark olive green to light brown to dark brown on the dorsal surface. A pale golden stripe runs from the nostril, across the eye, over the typanum, and down the side, underlined by a dark brown stripe, which also goes over the typanum, not across it. The forelimbs, groin, and thighs are dark red. The toes are three-quarters webbed and toe discs are large. The belly is white. Ecology and behaviour This species inhabits flowing streams in rainforest, woodland, and wet or dry sclerophyll forest along the coast and ranges of New South Wales. Males make an "Erk..Ek..Ek..Derk" call from stream-side vegetation during spring, summer and autumn, especially on warm nights; they are often seen in suburban creeks ...

Lismore, New South Wales
Lismore is a city in northeastern New South Wales, Australia and the main population centre in the City of Lismore Local government in Australia, local government area; it is also a regional centre in the Northern Rivers region of the State. It is situated on a low flood plain on the banks of the Wilsons River (New South Wales), Wilsons River near the latter's junction with Leycester Creek, both tributaries of the Richmond River which enters the Pacific Ocean at Ballina, New South Wales, Ballina, to the east. The original settlement initially developed as a grazing property in the 1840s, then became a timber and agricultural town and inland port based around substantial river traffic, which prior to the development of the road and rail networks was the principal means of transportation in the region. Use of the river for transport declined and then ceased around the mid-twentieth century, however by that time Lismore (which was elevated to city status in 1946) had become well est ...

Dorrigo, New South Wales
Dorrigo, a small town on the Waterfall Way, is located on the Northern Tablelands, in northern New South Wales, Australia. The town is part of Bellingen local government area. It is approximately north of the state capital, Sydney via the Pacific Highway, and west from the coastal city of Coffs Harbour. The town is situated on the Dorrigo Plateau near the New England Escarpment, which is part of the Great Dividing Range. Dorrigo is above sea level. At the 2016 census, Dorrigo had a population of 1,042 people. History The area now known as Dorrigo lies on the traditional land of the Gumbainggir people. European settlement of the area followed on from the early timber cutters in the 1860s. The first official European in the district was Land Commissioner Oakes who sighted the mouth of the Bellinger River. Dorrigo is derived from the Aboriginal word, ''dondorrigo'' or Dandarrga, meaning "stringy-bark". For many decades it was believed that explorer and settler Major Edward ...
