Cnemaspis Jacobsoni
''Cnemaspis jacobsoni'' is a species of gecko, a lizard in the family Gekkonidae. The species is native to Indonesia. Etymology The specific name, ''jacobsoni'', is in honor of Dutch naturalist Edward Richard Jacobson (1870–1944). Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Cnemaspis jacobsoni'', p. 132). Geographic range ''C. jacobsoni'' is endemic to the island of Simeulue, Indonesia. Habitat The preferred natural habitat of ''C. jacobsoni'' is forest. Description Small for its genus, ''C. jacobsoni'' may attain a snout-to-vent length (SVL) of . Males have neither femoral pores nor preanal pores. Reproduction ''C. jacobsoni'' is oviparous.

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alexander Strauch
Alexander Strauch (1 March 1832, in Saint Petersburg – 14 August 1893, in Wiesbaden, Germany) was a Russian naturalist, most notably a herpetologist. In 1861 he started working as a curator of the zoological museum at the Imperial Academy of Sciences in St. Petersburg. From 1879 to 1890 he was director of the museum. He is credited with establishing St. Petersburg as a major world center in the field of herpetology. Taxa named after Strauch Taxon, Taxa with the Specific name (zoology), specific epithet of ''strauchi'' or ''strauchii'' commemorate his name, five examples being: *''Blanus strauchi'' (Jacques von Bedriaga, Bedriaga, 1884) *''Ctenotus strauchii'' (George Albert Boulenger, Boulenger, 1887) *''Eremias strauchi'' Karl Fedorovich Kessler, Kessler, 1878 *''Gloydius strauchi'' (Bedriaga, 1912) *''Phrynocephalus, Phrynocephalus strauchi'' Alexander Mikhailovich Nikolsky, Nikolsky, 1899.

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] |
Femoral Pore
Femoral pores are a part of a holocrine secretory gland found on the inside of the thighs of certain lizards and amphisbaenians which releases pheromones to attract mates or mark territory. In certain species only the male has these pores and in other species, both sexes have them, with the male's being larger. Femoral pores appear as a series of pits or holes within a row of scales on the ventral portion of the animal's thigh. Femoral pores are present in all genera in the families Cordylidae, Crotaphytidae, Hoplocercidae, Iguanidae, Phrynosomatidae, and Xantusiidae. They are absent in all genera in the Anguidae, Chamaeleonidae, Dibamidae, Helodermatidae, Scincidae, Xenosauridae, and Varanidae families. They are present in other lizards and amphisbaenians quite variably, some geckoes, ''Phelsuma'', for example have these pores, others in the same family do not. In the desert iguana (''Dipsosaurus dorsalis''), the waxy lipids released from the femoral pores absorb ultravio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snout–vent Length
Snout–vent length (SVL) is a morphometric measurement taken in herpetology from the tip of the snout to the most posterior opening of the cloacal slit (vent)."direct line distance from tip of snout to posterior margin of vent" It is the most common measurement taken in herpetology, being used for all amphibians, lepidosaurs, and crocodilians (for turtles, carapace length (CL) and plastral length (PL) are used instead). The SVL differs depending on whether the animal is struggling or relaxed (if alive), or various other factors if it is a preserved specimen. For fossils, an osteological correlate Osteological correlates are marks on the bones of animals that are made from the causal interactions of the soft-tissue Soft tissue is all the tissue in the body that is not hardened by the processes of ossification or calcification such as bo ... such as precaudal length must be used. When combined with weight and body condition, SVL can help deduce age and sex. Advantages Bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simeulue
Simeulue is an island of Indonesia, off the west coast of Sumatra. It covers an area of 1754 square kilometres (677 square miles), including minor offshore islands. It had a population of 80,674 at the 2010 census and 92,865 at the 2020 census. The official estimate as at mid 2021 was 93,762. Its capital is Sinabang. Simeulue was once a part of West Aceh Regency but was split off in 1999 and became a separate Simeulue Regency. Demographics From the ethnic point of view the inhabitants of Simeulue are similar to the people of neighboring Nias Island. Two languages and a number of dialects are spoken on the island: Simeulue and Sigulai, which are different from the languages spoken in the north of Sumatra. The majority of the island's population is Muslim. History Simeulue was historically known to European mariners as "Hog Island"JH Moor '' Notices of the Indian Archipelago'' (1837) p103; retrieved 27 January 2019 and served as a landfall for ships seeking ports on the we ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
