Allied Rock-wallaby
The allied rock-wallaby or Weasel rock-wallaby (''Petrogale assimilis'') is a species of rock-wallaby found in northeastern Queensland, Australia. It forms part of the ''P. lateralis/penicillata'' species complex and is very similar to six other species of rock-wallaby found in this area; these include the Cape York rock-wallaby (''P. coenensis''), the unadorned rock-wallaby (''P. inornata''), the Herbert's rock-wallaby (''P. herberti''), the Godman's rock-wallaby (''P. godmani''), the Mareeba rock-wallaby (''P. mareeba'') and the Mount Claro rock-wallaby (''P. sharmani''). Description Few features distinguish the allied rock-wallaby from its close relatives but each species lives in a different part of Queensland and northern New South Wales; where their ranges overlap slightly, there is some hybridisation. They all have upper parts that range from brown to grey, and paler underparts. They usually have a dark muzzle and a dark patch aroun ...

Magnetic Island
Magnetic Island ( Wulguru: ''Yunbenun'') is an island offshore from the city of Townsville, Queensland, Australia. This mountainous island in Cleveland Bay has effectively become a suburb of Townsville. The island is accessible from Townsville Breakwater to Nelly Bay Harbour by ferry. There is a large National Park and bird sanctuary and walking tracks can be taken between the populated bays and to a number of tourist destinations such as the World War II forts. The island is a holiday destination with many hotels and several resorts in operation to cater for all levels of service. The public facilities and infrastructure on the island are managed by the Townsville City Council. The island is part of the electoral district of Townsville in the Legislative Assembly of Queensland, and part of the federal seat of Herbert, which is represented by Phillip Thompson. There are five settlements, namely Arcadia, Horseshoe Bay, Nelly Bay, Picnic Bay, and West Point. Geograph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bowen River (Queensland)
The Bowen River is a river in North Queensland, Australia. Course and features Formed by the confluence of the Broken River and the Little Bowen River near Tent Hill in the Normanby Range, part of the Great Dividing Range, the Bowen River flows in a north-westerly direction along the base of the range then flows west across Emu Plains and is crossed by the Bowen Developmental Road just north of Havilah. The river then flows north-west again between the Herbert Range and Leichhardt Range then discharges into the Burdekin River, south southeast of . The river descends over its course. The catchment area of the river occupies of which an area of is composed of riverine wetlands. The catchment is in poor condition with much of the riparian habitat having been cleared and prone to erosion. The area is mostly used for cattle grazing with the towns of Collinsville and Glendon both drawing their town water supply from the Bowen River Weir. The river has a mean annual discharge of ...

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 ...

Mammals Of Queensland
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, ...

Introduced Predators
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Gestation Period
In mammals, pregnancy is the period of reproduction during which a female carries one or more live offspring from implantation in the uterus through gestation. It begins when a fertilized zygote implants in the female's uterus, and ends once it leaves the uterus. Fertilization and implantation During copulation, the male inseminates the female. The spermatozoon fertilizes an ovum or various ova in the uterus or oviducts, and this results in one or multiple zygotes. Sometimes, a zygote can be created by humans outside of the animal's body in the artificial process of in-vitro fertilization. After fertilization, the newly formed zygote then begins to divide through mitosis, forming an embryo, which implants in the female's endometrium. At this time, the embryo usually consists of 50 cells. Development After implantation A blastocele is a small cavity on the center of the embryo, and the developing embryonary cells will grow around it. Then, a flat layer cell forms on the ...

Monogamy In Animals
Some animal species have a monogamous mating system, in which pairs bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamous mating Monogamy is defined as a pair bond between two adult animals of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy may either be short-term, lasting one to a few seasons or long-term, lasting many seasons and in extreme cases, life-long. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another.Ophir, Alexander G., Phelps, Steven M., Sorin, Anna Bess & O. Wolff, J.

Palm Island, Queensland
Palm Island is a Suburbs and localities (Australia), locality consisting of an island group of 16 islands, split between the Shire of Hinchinbrook and the Aboriginal Shire of Palm Island, in Queensland, Australia. The locality coincides with the geographical entity known as the Palm Island group, also known as the Greater Palm group, originally named the Palm Isles. However, the term "Palm Island" is most often used to refer to the main island, Great Palm Island, the largest island in the group and the only one with a significant population of permanent residents, most of whom are Aboriginal Australian, Aboriginal. The island is also known by the name "Bwgcolman", meaning "one people from many groups", derived from an Aboriginal Australian languages, Aboriginal language of one of the earliest groups of Aboriginal people removed from the mainland and settled there from 1918 onwards, during its use as an Aboriginal reserve.
