Calumma Tarzan
''Calumma tarzan'', also known commonly as the Tarzan chameleon or Tarzan's chameleon, is a species of lizard in the family Chamaeleonidae. The species is endemic to the Alaotra-Mangoro region in Madagascar. Etymology The specific name, ''tarzan'', is in honor of Tarzan, the fictional jungle dweller created by Edgar Rice Burroughs. Physical characteristics ''C. tarzan'' is approximately in total length, in snout-vent length (SVL), with anteriorly fused rostral crests to form a "spade-like" snout that projects 1 millimeter beyond its snout tip. The chameleon has green to light yellow coloration and has a dark transversal band when it is stressed. This species has a very low casque in comparison to other chameleons. Sexual dimorphism ''C. tarzan'' males exhibit a brown to blackish casque and necks while females have a green to light yellow casque and neck. Females have a less pronounced rectangular rostral profile than males in the species. Geographic range and habitat ''C. t ...

Edgar Rice Burroughs
Edgar Rice Burroughs (September 1, 1875 – March 19, 1950) was an American author, best known for his prolific output in the adventure, science fiction, and fantasy genres. Best-known for creating the characters Tarzan and John Carter, he also wrote the ''Pellucidar'' series, the ''Amtor'' series, and the '' Caspak'' trilogy. Tarzan was immediately popular, and Burroughs capitalized on it in every way possible, including a syndicated Tarzan comic strip, movies, and merchandise. Tarzan remains one of the most successful fictional characters to this day and is a cultural icon. Burroughs's California ranch is now the center of the Tarzana neighborhood in Los Angeles, named after the character. Burroughs was an explicit supporter of eugenics and scientific racism in both his fiction and nonfiction; Tarzan was meant to reflect these concepts. Biography Early life and family Burroughs was born on September 1, 1875, in Chicago (he later lived for many years in the suburb of ...

Taxa Named By Jörn Köhler
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 2010
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Endemic Fauna Of Madagascar
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calumma
''Calumma'' is a genus of chameleons endemic and restricted to Madagascar. The species formerly named ''Calumma tigris'' was transferred to the genus '' Archaius'' by Townsend et al., when they found that it is more closely related to ''Rieppeleon'' than to ''Calumma''. The oldest fossil of the genus is known from the Early Miocene of Kenya, showing that the genus originated in Africa. Species groups Four species groups are recognised within the genus ''Calumma'' (originally proposed by Glaw & Vences in 1994), some of which may be only phenetic, while others are phylogenetically supported: ''Calumma furcifer'' species group Contents: ''Calumma furcifer, C. gastrotaenia, C. marojezense, C. guillaumeti, C. andringitraense, C. glawi, C. vencesi'' Species characterised by typically green body colouration, sleek body form, and generally no occipital lobes (flaps of skin posterior to the head; present only in ''C. glawi'') and no rostral appendage (present only in males of ''C. furc ...

Flagship Species
In conservation biology, a flagship species is a species chosen to raise support for biodiversity conservation in a given place or social context. Definitions have varied, but they have tended to focus on the strategic goals and the socio-economic nature of the concept, to support the marketing of a conservation effort. The species need to be popular, to work as symbols or icons, and to stimulate people to provide money or support. Species selected since the idea was developed in 1980s include widely recognised and charismatic species like the black rhinoceros, the Bengal tiger, and the Asian elephant. Some species such as the Chesapeake blue crab and the Pemba flying fox, the former of which is locally significant to Northern America, have suited a cultural and social context. Utilizing a flagship species has limitations. It can skew management and conservation priorities, which may conflict. Stakeholders may be negatively affected if the flagship species is lost. The use of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Habitat
Forest ecology is the scientific study of the interrelated patterns, processes, flora, fauna and ecosystems in forests. The management of forests is known as forestry, silviculture, and forest management. A forest ecosystem is a natural woodland unit consisting of all plants, animals, and micro-organisms (Biotic components) in that area functioning together with all of the non-living physical (abiotic) factors of the environment. Surrounding issues Forests have an enormously important role to play in the global ecosystem. Forests produce approximately 28% of the Earth's oxygen (the vast majority being created by oceanic plankton), they also serve as homes for millions of people, and billions depend on forests in some way. Likewise, a large proportion of the world's animal species live in forests. That's why we absolutely must protect them. Forest ecology helps to understand life in the forest. It shows how living organisms behave, live and survive. Furthermore, forest ecology a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habitat ...

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] |
