Undara Lava Tubes
The Undara Volcanic National Park is a national park in the Shire of Etheridge, Queensland, Australia. It is situated 275 kilometres southwest of Cairns just off the Gulf Developmental Road. The park was established in 2009 to protect Australia longest lava tube and the unique fauna and flora found of the area. The basalts of the area form part of the Cenozoic McBride Basalt (Volcanic) Provence. The volcanics are all less than 8 million years old (Ma) with the youngest only 7,000 years old. Location The Undara Volcanic National Park is situated 437 km northwest of Townsville and 275 km southwest of Cairns, the two major regional centres of North Queensland. The National Park is 58 kilometres by road from the small town of Mount Surprise. The National Park is approximately 61,500 hectares in area. The climate is monsoonal and is generally hot and humid. It can be very wet from October to late March. The drier cooler months are April to August. The Queensland Department of E ...

Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antilopine Kangaroo
The antilopine kangaroo (''Osphranter antilopinus''), also known as the antilopine wallaroo or the antilopine wallaby, is a species of macropod found in northern Australia: in Cape York Peninsula in Queensland, the Top End of the Northern Territory, and the Kimberley region of Western Australia. It is a locally common, gregarious grazer. Taxonomy The description of the species by John Gould was published in 1842, one of four new species of 'kangaroos' presented before the Zoological Society of London in 1841. The type location was given as Port Essington. The author assigned the new species to the genus ''Osphranter'', a taxon later submerged as a subgenus of ''Macropus'', and recognised an affinity with his earlier description of ''Macropus robustus'' (known as the common wallaroo or euro). A taxonomic restructuring in 2019, based on genetic analysis, promoted ''Osphranter'' back to genus level, redefining the antilopine kangaroo and the red kangaroo, among others, as spec ...

Common Wallaroo
The common wallaroo (''Osphranter robustus''), also known as the euro, hill wallaroo, or simply wallaroo, is a species of macropod. The word ''euro'' is particularly applied to one subspecies (''O. r. erubescens'').WE Poole and JC Merchant (1987): ''Reproduction in Captive Wallaroos - the Eastern Wallaroo, Macropus-Robustus-Robustus, the Euro, Macropus-Robustus-Erubescens and the Antilopine Wallaroo, Macropus-Antilopinus.'' Australian Wildlife Research 14(3) 225 - 242online link/ref> The eastern wallaroo is mostly nocturnal and solitary, and is one of the more common macropods. It makes a loud hissing noise and some of the other subspecies are sexually dimorphic, like most wallaroos. Subspecies There are four subspecies: *the eastern wallaroo (''O. r. robustus'') – found in eastern Australia; males of this subspecies have dark grey fur, almost resembling the black wallaroo (''Osphranter bernardus''). Females are lighter, being almost sandy in colour. *the euro or western wall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macropodidae
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands. Description Although omnivorous kangaroos lived in the past, modern macropods are herbivorous. Some are browsers, but most are grazers and are equipped with appropriately specialised teeth for cropping and grinding up fibrous plants, in particular grasses and sedges. In general, macropods have a broad, straight row of cutting teeth at the front of the mouth, no canine teeth, and a gap before the molars. The molars are large and, unusually, do not appear all at once but a pair at a time at the back of the mouth as the animal ages, eventually becoming worn down by the tough, abrasive grasses and falling out. Like many Macropodiformes, early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Horseshoe Bat
The smaller horseshoe bat (''Rhinolophus megaphyllus'') is a species of bat in the family Rhinolophidae. It is found in Australia and Papua New Guinea. Taxonomy A species was first described by John Edward Gray in 1834, using a specimen provided by George Bennett that had been collected in a cave near the Murrimbidgee River. Noted as the ''megaphyllus''-species group, subsuming earlier taxa ranked as species and separating other these previously allied to the species complex. Five subspecies were recognised by '' Mammal Species of the World'' (Simmons, 2005) * ''Rhinolophus megaphyllus'' J. E.

Horseshoe Bat
Horseshoe bats are bats in the family Rhinolophidae. In addition to the single living genus, ''Rhinolophus'', which has about 106 species, the extinct genus '' Palaeonycteris'' has been recognized. Horseshoe bats are closely related to the Old World leaf-nosed bats, family Hipposideridae, which have sometimes been included in Rhinolophidae. The horseshoe bats are divided into six subgenera and many species groups. The most recent common ancestor of all horseshoe bats lived 34–40 million years ago, though it is unclear where the geographic roots of the family are, and attempts to determine its biogeography have been indecisive. Their taxonomy is complex, as genetic evidence shows the likely existence of many cryptic species, as well as species recognized as distinct that may have little genetic divergence from previously recognized taxa. They are found in the Old World, mostly in tropical or subtropical areas, including Africa, Asia, Europe, and Oceania. Horseshoe bats are ...

Eastern Cave Bat
The eastern cave bat or Troughton's forest bat (''Vespadelus troughtoni'') is a species of vesper bat Vespertilionidae is a family of microbats, of the order Chiroptera, flying, insect-eating mammals variously described as the common, vesper, or simple nosed bats. The vespertilionid family is the most diverse and widely distributed of bat familie ... in the family Vespertilionidae. It is found only in Australia, where it lives in caves along the east coast and in adjacent inland ranges.Ellis, M. (2001).

Bent-wing Bat
''Miniopterus'', known as the bent-winged or long winged bats, is the sole genus of the family Miniopteridae. They are small flying insectivorous mammals, micro-bats of the order Chiroptera, with wings over twice the length of the body. The genus had been placed in its own subfamily among the vespertilionid bats, as Miniopterinae, but is now classified as its own family. Taxonomy The genus was erected in 1837 by Charles L. Bonaparte. In the first systematic revision of the genus, published in a monograph of ''Miniopterus'' in 1858 by Robert F. Tomes, the author reallocated specimens and described new taxa. A new systematic arrangement was produced in an extensive study of poorly known chiropterans of the Indo-Austral region by James E. Hill in 1985, the greater resolution of the genus being determined by the British Museum of Natural History's acquisition of new series of specimens collected in Fiji, the New Hebrides and New Caledonia and the extensive collection made in New ...

Red Goshawk
The red goshawk (''Erythrotriorchis radiatus'') is probably the rarest Australian bird of prey. It is found mainly in the savanna woodlands of northern Australia, particularly near watercourses. It takes a broad range of live prey, mostly birds. Taxonomy The red goshawk was first described by the English ornithologist John Latham in 1801 under the binomial name ''Falco radiatus''. The species used to be regarded as a very large member of the goshawk subfamily, Accipitrinae, but it is now believed that the resemblance to these other birds is convergent. Experts now group the red goshawk with the superficially dissimilar black-breasted buzzard ''Hamirostra melanosternon'' and square-tailed kite ''Lophoictinia isura'' as one of the Australasian old endemic raptors. It is believed that the ancestors of these birds, possibly together with a handful of species from South-east Asia and Africa, occupied Gondwana and over millions of years have diverged into their current forms.

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
