Wilderness
Wilderness or wildlands (usually in the plural), are natural environments on Earth that have not been significantly modified by human activity or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one quarter of Earth's terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity. Some governments establish protection for wilderness areas by law to not only preserve what already exists, but also to promote and advance a natural expression and development. These can be set up in preserves, conservation preserves, national forests, national parks and even in urban areas along rivers, gulches or otherwise undeveloped areas. Often these areas are considered important for the survival of c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wedge-tailed Eagle
The wedge-tailed eagle (''Aquila audax'') is the largest bird of prey in the continent of Australia. It is also found in southern New Guinea to the north and is distributed as far south as the state of Tasmania. Adults of this species have long, broad wings, fully feathered legs, an unmistakable wedge-shaped tail, an elongated maxilla, a strong beak and powerful feet. The wedge-tailed eagle is one of 12 species of large, predominantly dark-coloured booted eagles in the genus '' Aquila'' found worldwide. Genetic research has clearly indicated that the wedge-tailed eagle is fairly closely-related to other, generally large members of the ''Aquila'' genus.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O.

Willie Wagtail
The willy (or willie) wagtail (''Rhipidura leucophrys'') is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and Eastern Indonesia. It is a common and familiar bird throughout much of its range, living in most habitats apart from thick forest. Measuring in length, the willie wagtail is contrastingly coloured with almost entirely black upperparts and white underparts; the male and female have similar plumage. Three subspecies are recognised; ''Rhipidura leucophrys leucophrys'' from central and southern Australia, the smaller ''R. l. picata'' from northern Australia, and the larger ''R. l. melaleuca'' from New Guinea and islands in its vicinity. It is unrelated to the true wagtails of the genus '' Motacilla''; it is a member of the fantail genus ''Rhipidura'' and is a part of a "core corvine" group that includes true crows and ravens, drongos and birds of paradise. Within this group, fantails are placed either in the family Dic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echidna
Echidnas (), sometimes known as spiny anteaters, are quill-covered monotremes (egg-laying mammals) belonging to the family Tachyglossidae . The four extant species of echidnas and the platypus are the only living mammals that lay eggs and the only surviving members of the order Monotremata. The diet of some species consists of ants and termites, but they are not closely related to the true anteaters of the Americas, which (along with sloths and armadillos) are xenarthrans. Echidnas live in Australia and New Guinea. Echidnas evolved between 20 and 50 million years ago, descending from a platypus-like monotreme. This ancestor was aquatic, but echidnas adapted to life on land. Etymology Echidnas are named after Echidna, a creature from Greek mythology who was half-woman, half-snake, as the animal was perceived to have qualities of both mammals and reptiles. An alternative explanation is a confusion with . Physical characteristics Echidnas are medium-sized, solitary mamm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallaroo
Wallaroo is a common name for several species of moderately large macropods, intermediate in size between the kangaroos and the wallabies. The word "wallaroo" is from the Dharug ''walaru'', and not a portmanteau of the words "kangaroo" and "wallaby", as is commonly assumed. Description Wallaroos are typically distinct species from kangaroos and wallabies. An exception is the antilopine wallaroo, which is commonly known as an antilopine kangaroo when large, an antilopine wallaby (when small), or an antilopine wallaroo when of intermediate size. Species Wallaroo may refer to one of several species in the genus ''Osphranter'': * The common wallaroo or wallaroo (''Osphranter robustus'') is the best-known species. There are four subspecies of the common wallaroo: the eastern wallaroo (''O. r. robustus'') and the euro (''O. r. erubescens''), which are both widespread, and two of more restricted range, one from Barrow Island (the Barrow Island wallaroo (''O. r. isabellinus'')), ...

Bibron's Toadlet
The Bibron's toadlet or brown toadlet (''Pseudophryne bibronii'') is a species of Australian ground-dwelling frog that, although having declined over much of its range, is widespread through most of New South Wales, Victoria, south-eastern Queensland, and eastern South Australia, including Kangaroo Island. Bibron's toadlet settles in a wide variety of habitats within these region but they mainly reside in dry forests, woodland, shrubland, grassland, coastal swamps, heathland, and sub-alpine areas. They deposit their eggs in leaf litters during the flooding season, which is essential for the proper development of the egg. This species has high sexual dimorphism within the species and utilizes chemosignals to attract potential mates. Taxonomy The genus ''Pseudophryne'' encapsulates 14 different species of frogs localized to Australia. These frogs are morphologically similar to small bufonid frogs not localized to Australia. The first known nomenclature of the ''Pseudophryne'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ephemeral
Ephemerality (from the Greek word , meaning 'lasting only one day') is the concept of things being transitory, existing only briefly. Academically, the term ephemeral constitutionally describes a diverse assortment of things and experiences, from digital media to types of streams. "There is no single definition of ephemerality". With respect to unique performances, for example, it has been noted that " hemerality is a quality caused by the ebb and flow of the crowd's concentration on the performance and a reflection of the nostalgic character of specific performances". Because different people may value the passage of time differently, ephemerality may be a relative, perceptual concept: "In brief, what is short-lived may not be the object itself, but the attention we afford it".Ronald Beiner, ''Political Philosophy: What It Is and Why It Matters'' (2014), p. 10. Ephemerality and nature Geographical features An ephemeral stream is that which only exists following precipitation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulkathunha-Gammon Ranges National Park
The Vulkathunha-Gammon Ranges National Park is a protected area in the Flinders Ranges of South Australia, immediately south-west of and adjacent to the Arkaroola Protection Area. They encompass some of the most rugged and spectacular country in South Australia. Geography The central ranges are of a different topographical nature to the rest of the Flinders, being composed of roughly flat-lying strata, creating a high plateau into which spectacular gorges have been cut, instead of the buckled and folded strata further south which lead to the ubiquitous cuestas of Wilpena Pound. The Gammons are dominated by "The Plateau" in the southwest, which is contiguous with and of much the same height as the Blue Range further northeast, culminating in Benbonyathe Hill (1064m), the highest point in the Flinders north of Wilpena. Other summits on the largely flat range and plateau include Elephant Hill (with adjacent outliers North Tusk and South Tusk), Mount Changeweather, Four Winds Hill, ...
