Savanna Glider
The savanna glider (''Petaurus ariel'') is a species of arboreal gliding possum in the genus '' Petaurus''. Taxonomy It was long considered a subspecies of the sugar glider (''P. breviceps''), but a 2020 study split ''P. breviceps'' into 3 distinct species, with ''P. ariel'' being found to represent one of these distinct species. Names The Bininj of western Arnhem Land, Australia call this animal lambalk in their Kunwinjku language. Description The species somewhat resembles a small squirrel glider (''P. norfolcensis'') with a pointed nose. It displays substantial body size variation throughout its range; in the northern, more coastal portions, it is small enough to be considered the smallest of all Australian ''Petaurus''. However, in the arid inland parts of its range to the south, it can grow to be twice as large. Distribution The species lives in the wooded savannas of northern Australia. It ranges from northwestern Queensland west through the Northern Territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist who published monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould (illustrator), Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. Because of his 1840s seven-volume series ''The Birds of Australia (Gould), The Birds of Australia'' and its updates he has been considered the father of bird study in Australia, and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life John Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained ...

Cobourg Peninsula
The Cobourg Peninsula is a peninsula located east of Darwin in the Northern Territory, Australia. It is deeply indented with coves and bays, covers a land area of about , and is virtually uninhabited with a population ranging from about 20 to 30 in five family outstations, but without any notable settlement or village. It is separated from Croker Island in the east by Bowen Strait, which is wide in the south and up to in the north, and long. In the west, it is separated from Melville Island by Dundas Strait. From Cape Don, the western point of the peninsula, to Soldier Point in the east of Melville Island, the distance is . In the north is the Arafura Sea, and in the south the Van Diemen Gulf. The highest elevation is Mount Roe in the south with an altitude of . Name The peninsula was named after Prince Leopold of Saxe-Coburg, later known as Leopold I of Belgium, by Phillip Parker King. The French spelling of the name has been retained over the years. Development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1842
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...

Marsupials Of Australia
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including kangaroos, koalas, opossums, possums, Tasmanian devils, wombats, wallabies, and bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian continent, including mainland Australia, Tasmania, New Guinea, and nearby islands. The remainin ...

Gliding Possums
There are many different types of gliding possum, sometimes referred to as volplane possum, flying phalangers, or simply as gliders, endemic to Australia and New Guinea. Taxonomically, gliding possums occupy three genera.

Fire Regime
A fire regime is the pattern, frequency, and intensity of the bushfires and wildfires that prevail in an area over long periods of time. It is an integral part of fire ecology, and renewal for certain types of ecosystems. A fire regime describes the spatial and temporal patterns and ecosystem impacts of fire on the landscape, and provides an integrative approach to identifying the impacts of fire at an ecosystem or landscape level.Morgan, Penelope; Hardy; Swetnam; Rollins; Long (1999)"Mapping fire regimes across time and space: Understanding coarse and fine-scale fire patterns"(PDF). '' International Journal of Wildland Fire''. 10: 329–342 – via Google Scholar. If fires are too frequent, plants may be killed before they have matured, or before they have set sufficient seed to ensure population recovery. If fires are too infrequent, plants may mature, senesce, and die without ever releasing their seed. Fire regimes can change with the spatial and temporal variations in topograph ...

Feral Cats In Australia
Cats (''Felis catus''), initially introduced into Australia with the First Fleet in 1788, now number more than 11 million distributed across more than 90% of the continent including every major island. They are the second most popular pet by household (third most populous overall after dogs and fish). In 2023 there were 5.3 million kept as pets of which approximately 95% are neutered. In addition there are estimated to be up to 6 million feral cats found in almost every remote area across the country. Cats are considered by the CSIRO to be the most damaging invasive pest by costPest plants and animals cost Australia aroun ...
