Red Foxes In Australia
Red foxes pose a serious conservation problem in Australia. 2012 estimates indicate that there are more than 7.2 million red foxes (''Vulpes vulpes'') and growing with a range extending throughout most of the continental mainland. The species became established in Australia through successive introductions by settlers in 1830s. Due to its rapid spread and ecological impact it has classified as one of the most damaging invasive species in Australia. Introduction and spread Red foxes were introduced to the British colonies of Van Diemen's Land (as early as 1833) and the Port Phillip District and Sydney Regions of New South Wales (as early as 1845) for the purpose of the traditional English sport of fox hunting. Curiously a permanent fox population was not established on the island of Tasmania and it is widely held that they were outcompeted by the Tasmanian devil. On the mainland, however, the species was successful as an apex predator. The spread of red foxes across the south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Rabbit Plagues In Australia
Rabbit plagues in Australia have occurred several times throughout parts of Australia since wild European rabbits were introduced by European colonists. Introduction Rabbits were introduced to Australia with the arrival of the First Fleet in 1788. A population of 24 rabbits were released near Geelong in 1859 to be hunted for sport. The native quolls predated upon rabbits and prior to 1870, many accounts recorded quolls impeding their establishment on the mainland while island colonies thrived. Quolls were systematically exterminated by colonists to defend introduced species such as chickens. Within 50 years rabbits had spread throughout most of the continent with devastating impact on indigenous flora and fauna. The species had spread throughout Victoria and by 1880 was found in New South Wales. Rabbits were found in South Australia and Queensland by 1886 and by 1890 were in eastern parts of Western Australia and the Northern Territory in the 1900s. Feral rabbits were fo ...

Mouse Plagues In Australia
Mouse plagues have occurred several times throughout parts of Australia since wild house mouse, house mice (''Mus musculus'') were introduced by European colonists along with the First Fleet in 1788. Australia and China are the two countries in the world where plagues of mice are known to occur. Mouse plagues occur in southern and eastern Australia, usually in the grain-growing regions, around every four years. Aggregating around food sources during plagues, mice can reach a density of up to . History Early mice plagues Mice probably arrived in Australia as stowaways on board the First Fleet of British colonists in 1788. An early localised plague of mice occurred around Walgett, New South Wales, Walgett in New South Wales in 1871. In 1872 another plague was recorded near Saddleworth, South Australia, Saddleworth in South Australia with farmers ploughing the soil to destroy mice nests. 1880s and 1890s In 1880 a plague of mice was noted along an area of the Goulburn River ...

Quokka
The quokka (''Setonix brachyurus'', ) is a small macropod about the size of a domestic cat. It is the only member of the genus ''Setonix''. Like other marsupials in the macropod family (such as kangaroos and wallabies), the quokka is herbivorous and mainly nocturnal. Quokkas are found on some smaller islands off the coast of Western Australia, particularly Rottnest Island just off Perth and Bald Island near Albany. Isolated, scattered populations also exist in forest and coastal heath between Perth and Albany. A small colony inhabits a protected area of Two Peoples Bay Nature Reserve, where they co-exist with the critically endangered Gilbert's potoroo. Description A quokka weighs and is long with a tail, which is quite short for a macropod. It has a stocky build, well developed hind legs, rounded ears, and a short, broad head. Its musculoskeletal system was originally adapted for terrestrial bipedal saltation, but over its evolution, its system has been built for arb ...

Bridled Nail-tail Wallaby
The bridled nail-tail wallaby (''Onychogalea fraenata''), also known as the bridled nail-tailed wallaby, bridled nailtail wallaby, bridled wallaby, merrin, and flashjack, is a vulnerable species of macropod. It is a small wallaby found in three isolated areas in Queensland, Australia, and whose population is declining. In early 2019 the total population of the species was estimated to be fewer than 500 mature individuals in the wild and 2285 in captivity. Taxonomy A specimen was presented to the Linnean Society of London by John Gould in 1840, and published in the society's journal the following year. The date of first publication has been the source of conjecture, and it has been proposed that this was in a 1840 issue of '' The Athenaeum''. Gould obtained his specimens while in Australia, returning these to England for scientific examination; he gave the animal the common name bridled kangaroo.

Numbat
The numbat (''Myrmecobius fasciatus''), also known as the noombat or walpurti, is an insectivorous marsupial. It is diurnal and its diet consists almost exclusively of termites. The species was once widespread across southern Australia, but is now restricted to several small colonies in Western Australia. It is therefore considered an endangered species and protected by conservation programs. Numbats were recently re-introduced to fenced reserves in South Australia and New South Wales. The numbat is the faunal emblem of Western Australia. Taxonomy The numbat genus ''Myrmecobius'' is the sole member of the family Myrmecobiidae, one of four families that make up the order Dasyuromorphia, the Australian marsupial carnivores. The species is not closely related to other extant marsupials; the current arrangement in the order Dasyuromorphia places its monotypic family with the diverse and carnivorous species of Dasyuridae. Genetic studies have shown the ancestors of the numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rufous Bettong
The rufous rat-kangaroo or rufous bettong (''Aepyprymnus rufescens'') is a small, jumping, rat-like mammal native to eastern Australia. It is the only species in the genus ''Aepyprymnus''. The largest member of the rat-kangaroo family (Potoroidae), it is about the size of a rabbit. The rufous rat-kangaroo is active at night when it digs for plant roots and fungi, and like other marsupials it carries its young in a pouch. Though its range is reduced, the population is healthy and stable. Taxonomy The rufous rat-kangaroo is the only member of its genus, and is the largest of all the potoroids. It is generally grey with a hint of reddish brown and its scientific name means "reddish high-rump". It was once thought of as a solitary, nocturnal animal, but recent observation indicates that the rufous rat-kangaroo may form loose, polygynous associations. It feeds mostly on tubers and fungi, but also on leaves and other vegetation. Description A species of the family Potoroidae (rat ...

Boodie
The boodie (''Bettongia lesueur''), also known as the burrowing bettong or Lesueur's rat-kangaroo, is a small, furry, rat-like mammal native to Australia. Once common throughout the continent, it is now restricted to a few coastal islands. A member of the rat-kangaroo family (Potoroidae), it lives in burrows and is active at night when it forages for fungi, roots, and other plant matter. It is about the size of a rabbit and, like other marsupials, carries its young in a pouch. Before European settlement, it was the most common macropod in Australia (a group that includes kangaroos, wallabies, and other Australian mammals). Competition and predation by introduced rabbits, cats, and foxes, as well as habitat loss, pressured the population. It was declared a pest in the 1900s and was wiped out by the 1960s; however, the loss of the boodie and other ground-foraging animals has degraded soil quality. Populations persisted on three west coast islands (Bernier, Dorre, and Barrow), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
