Gehyra Dubia
Dubious dtella, the native Australian house gecko, or dubious four-clawed gecko (''Gehyra dubia'') is a species of gecko in the genus ''Gehyra'', native to Northeastern Australia (Queensland and northern New South Wales as well as islands of the Great Barrier Reef and the Torres Strait). The lizard is found in a variety of habitats, including acacia and eucalyptus woodlands, and in human-developed habitats, such as house walls in urban areas. Its urban presence makes it known as a common house gecko in Queensland. These geckos are often confused with the Asian common house gecko, which was introduced to Australia from Indonesia, but ''G. dubia'' has distinct rounded feet and quieter calls. Physical description ''Gehyra dubia'' is a small gecko; its snout-to-vent length ranges up to 6 cm, and its tail length ranging up to 14 cm. Body size does not vary significantly between the sexes. While resting, they are typically a dull gray-brown color and carry dark spots all ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Oviparous
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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Spotted Python
The spotted python, also known as the small-blotched python, eastern small-blotched python, or eastern Children's python (''Antaresia maculosa'') is a python species found in northern Australia and New Guinea. It is a popular pet among Australian reptile enthusiasts and other reptile enthusiasts abroad due to its small size and even temperament. No subspecies were originally recognized. However, two subspecies were recognized as of 2020; ''A. m. maculosa'' and ''A. m. peninsularis''. The spotted pythons of New Guinea were proposed to be reclassified in 2021 as their own unique species, ''A. papuensis'' or the Papuan spotted python, in the same study that discovered the two mainland subspecies. However, both ITIS and The Reptile Database currently consider the two variants as synonyms. Taxonomy Wilhelm Peters described the spotted python in 1873. A new subspecies, ''A. m. brentonoloughlini'' was described by Hoser (2003), but this taxon is not considered valid by other herpet ...

Collett's Snake
Collett's snake (''Pseudechis colletti''), also commonly known as Collett's black snake, Collett's cobra, or Down's tiger snake, is a species of venomous snake in the family Elapidae. The species is native to Australia. Although Collett's snake is not as venomous as other Australian snakes, it is capable of delivering a fatal bite, ranking nineteenth in the world's most venomous snakes. Taxonomy and etymology Collett's snake is one of several species in the genus ''Pseudechis'' commonly known as black snakes. A study of mitochondrial DNA showed it to be most closely related to the blue-bellied black snake ('' P. guttatus''), with the Papuan black snake ('' P. papuanus'') as the next closest relative to the pair. Belgian-born British zoologist George Albert Boulenger described the species ''P. colletti'' in 1902, (''Pseudechis colletti'', new species). naming it in honour of Norwegian zoologist Robert Collett. A young snake had been collected by Collett, and Boulenger had noted i ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Brown Tree Snake
The brown tree snake (''Boiga irregularis''), also known as the brown catsnake, is an arboreal rear-fanged colubrid snake native to eastern and northern coastal Australia, eastern Indonesia (Sulawesi to Papua), Papua New Guinea, and many islands in northwestern Melanesia. This snake is infamous for being an invasive species responsible for extirpating the majority of the native bird population in Guam. It is also one of the very few colubrids found in Australia, where elapids are more common. Diet The brown tree snake preys upon birds, lizards, bats, and rats and other small rodents in its native range. It preys on birds and shrews in Guam.Pianka, Eric R.; King, Dennis; King, Ruth Allen. (2004). ''Varanoid Lizards of the World''. Indiana University Press, 588 pages They threaten local birds and lizards such as the Dubious dtella. Owing to the availability of prey and lack of predators in introduced habitats such as Guam, they have been known to grow to larger sizes than th ...

Death Adder (snake)
''Acanthophis'' is a genus of elapid snakes. Commonly called ''death adders'', they are native to Australia, New Guinea and nearby islands, and are among the most venomous snakes in the world. Despite their common name, they are not adders at all and belong to the Elapidae family (like cobras). The name of the genus derives from the Ancient Greek / ('spine') and / ('snake'), referring to the spine on the death adder's tail. Eight species are listed by ITIS, though it remains unclear how many species this genus includes, with figures ranging from 4 to 15 species being quoted. Taxonomy French naturalist François Marie Daudin established the genus ''Acanthophis'' in 1803, with the common death adder (''A. cerastinus'') as its only species. Although the death adders resemble vipers of the family Viperidae, they are actually members of the family Elapidae, which includes cobras, mambas, and coral snakes. It remains unclear how many species are included in this genus. Tradi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic c ...

Dubious Dtella Foraging In The House
Doubt is a mental state in which the mind remains suspended between two or more contradictory propositions, unable to be certain of any of them. Doubt on an emotional level is indecision between belief and disbelief. It may involve uncertainty, distrust or lack of conviction on certain facts, actions, motives, or decisions. Doubt can result in delaying or rejecting relevant action out of concern for mistakes or missed opportunities. Psychology Partial or intermittent negative reinforcement can create an effective climate of fear and doubt. Philosophy Descartes employed Cartesian doubt as a pre-eminent methodological tool in his fundamental philosophical investigations. Branches of philosophy like logic devote much effort to distinguish the dubious, the probable and the certain. Much of illogic rests on dubious assumptions, dubious data or dubious conclusions, with rhetoric, whitewashing, and deception playing their accustomed roles. Theology Doubt as a path towards (d ...

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Generalist And Specialist Species
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food), others less so, and some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species. Description Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nocturnality
Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing, smell, and specially adapted eyesight. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsiers and some owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intense sunlight. Diurnal animals, including squirrels and songbirds, are active d ...
