Ctenophorus Mirrityana
The Barrier Range dragon (''Ctenophorus mirrityana'') is an Agamidae, agamid lizard which has been newly described (2013) as a separate species from the Ctenophorus decresii, tawny dragon (''Ctenophorus decresii''). This species is endemic to Australia, restricted to just three sites in western New South Wales (NSW). Taxonomy ''C. mirrityana'' is the newest member of the ''Ctenophorus decresii'' complex, which originally comprised four closely related, rock-dwelling species. As a member of the Agamidae lizard family, this dragon is characterised by its well-developed limbs and rough scales. Currently made up of 33 species, ''Ctenophorus'' is the largest genus of agamid lizards in Australia, with most of these lizards found in arid areas. Assessment of its genetic, colour and anatomical differences to ''C. decresii,'' has led to the Barrier Range dragon being recognised as its own species. Description The Barrier Range dragon is a medium sized terrestrial lizard, which can r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agamidae
Agamidae is a family (biology), family of over 300 species of iguanian lizards indigenous to Africa, Asia, Australia, and a few in Southern Europe. Many species are commonly called dragons or dragon lizards. Overview phylogenetics, Phylogenetically, they may be sister to the Iguanidae, and have a similar appearance. Agamids usually have well-developed, strong legs. Their tails cannot be shed and regenerated like those of geckos (and several other families such as skinks), though a certain amount of regeneration is observed in some. Many agamid species are capable of limited change of their colours to regulate their body temperature. In some species, males are more brightly coloured than females, and colours play a part in signaling and reproductive behaviours. Although agamids generally inhabit warm environments, ranging from hot deserts to tropical rainforests, at least one species, the mountain dragon, is found in cooler regions. They are particularly diverse in Australia. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenophorus Decresii
''Ctenophorus decresii'', also known commonly as the tawny dragon or the tawny crevice-dragon, is a species of lizard in the family Agamidae. The species is endemic to Australia. The average snout-to-vent length (SVL) of the species is with larger individuals being around and smaller individuals around . The optimal time for mating in this species is two to three weeks after the females emerge from hibernation. Eggs are typically laid from September to October with most of them being laid earlier in the period. ''C. decresii'' is known for its variations in throat colors which change based on environmental conditions. Its primary food sources consist of both vegetation and invertebrates, and it prefers to live in rocky habitats. Etymology & taxonomy ''C. decresii'' is a member of the genus '' Ctenophorus'', which is a very diverse group of lizards found throughout Australia. The specific name, ''decresii'', refers to ''L'Île de Decrès'', which was the French name for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ctenophorus
''Ctenophorus'' is a genus of lizards, commonly known as comb-bearing dragons, in the family Agamidae. The genus contains the most diverse group of dragon lizards in Australia. It is the largest group of Australian lizards and it has an extensive radiation in the arid zones. Many of the species of ''Ctenophorus'' have been grouped by a similar morphology. The informal names and groupings within this genus — rock dragon, crevice-dragon, ground-dragon, sand-dragon, and bicycle-dragon — are named after the mythological creature, the dragon. Lizards in the genus ''Ctenophorus'' may be confused with lizards in the genera '' Tympanocryptis'' and ''Diporiphora''.

Adult Male Barrier Range Dragon
An adult is a human or other animal that has reached full growth. In human context, the term ''adult'' has meanings associated with social and legal concepts. In contrast to a "minor", a legal adult is a person who has attained the age of majority and is therefore regarded as independent, self-sufficient, and responsible. They may also be regarded as a "major". The typical age of attaining legal adulthood is 18, although definition may vary by legal rights, country, and psychological development. Human adulthood encompasses psychological adult development. Definitions of adulthood are often inconsistent and contradictory; a person may be biologically an adult, and have adult behavior, but still be treated as a child if they are under the legal age of majority. Conversely, one may legally be an adult but possess none of the maturity and responsibility that may define an adult character. In different cultures there are events that relate passing from being a child to becoming ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mutawintji National Park
The Mutawintji National Park, formerly the Mootwingee National Park, is a protected national park that is located in the Far West region of New South Wales, in eastern Australia. The national park is situated approximately west of Sydney and about north-east of . Features and location The rugged, mulga-clad Byngnano Range is dissected by colourful gorges, rockpools and creek beds lined with red gums. Scattered among the caves and overhangs are Aboriginal rock art and engravings. In 1979, the Foundation for National Parks & Wildlife purchased and fenced , in the Coturaundee Ranges, now part of Mutawintji National Park, for the conservation and protection of the yellow-footed rock wallaby. Follow-up funding of fox eradication in the reserve ensured the survival of this last population of yellow-footed rock-wallabies in New South Wales. Of the wild animals, wedge-tailed eagle, peregrine falcon, short-billed correllas, zebra finches, budgerigars, apostle birds and magpies ca ...

Diurnality
Diurnality is a form of plant and ethology, animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food by sight, the risk of predation, and the time of year. Diurnality is a cycle of activity within a 24-hour period; cyclic activities called circadian rhythms are endogenous cycles not dependent on external cues or environmental factors except for a zeitgeber. Animals active during twilight are crepuscular, those active during the night are nocturnal and animals active at sporadic times during both night and day are cathemerality, cathemeral. Plants that open their flowers during the daytime are described as diurnal, while those that bloom during nighttime are nocturnal. The timing of flower opening is often related to the time at which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ectotherm
An ectotherm (from the Greek () "outside" and () "heat") is an organism in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature.Davenport, John. Animal Life at Low Temperature. Publisher: Springer 1991. Such organisms (for example frogs) rely on environmental heat sources, which permit them to operate at very economical metabolic rates. Some of these animals live in environments where temperatures are practically constant, as is typical of regions of the abyssal ocean and hence can be regarded as homeothermic ectotherms. In contrast, in places where temperature varies so widely as to limit the physiological activities of other kinds of ectotherms, many species habitually seek out external sources of heat or shelter from heat; for example, many reptiles regulate their body temperature by basking in the sun, or seeking shade when necessary in addition to a whole host of other behavioral thermo ...

Oviparity
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goat
The goat or domestic goat (''Capra hircus'') is a domesticated species of goat-antelope typically kept as livestock. It was domesticated from the wild goat (''C. aegagrus'') of Southwest Asia and Eastern Europe. The goat is a member of the animal family Bovidae and the tribe Caprini, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat.Hirst, K. Kris"The History of the Domestication of Goats".''About.com''. Accessed August 18, 2008. It is one of the oldest domesticated species of animal, according to archaeological evidence that its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago. Goats have been used for milk, meat, fur, and skins across much of the world. Milk from goats is often turned into goat cheese. Female goats are referred to as ''does'' or ''nannies'', intact males are called ''bucks'' or ''billies'', and juvenile goats of both sexes are called ''kids''. Castrated males are called ''wethers''. Whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
