Phelsuma Laticauda Angularis
''Phelsuma laticauda angularis'' Mertens, 1964 is a diurnal subspecies of geckos. It lives in northern Madagascar and typically inhabits different trees and houses. The Gold dust day gecko feeds on insects and nectar. Description This lizard is slightly smaller than the nominate form. It can reach a total length of about . The body colour is a bright green or yellowish green or rarely even blue. Typical for this day gecko are the yellow speckles on the neck and the upper back. There are three rust-coloured transverse bars on the snout and head. The upper eyelid is blue. In contrast to the nominate form, there is a wide, irregular, v-shaped marking which points to the head on the lower back. The tail is wider and flatter than in ''Phelsuma laticauda laticauda''. The ventral side is off-white. Distribution This day gecko inhabits northwest Madagascar. It is only known from the region around Antsohihy Antsohihy is a city (commune urbaine) in northern Madagascar. It is the a ...

Robert Mertens
Robert Friedrich Wilhelm Mertens (1 December 1894 – 23 August 1975) was a German herpetologist. Several taxa of reptiles are named after him.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii. ("Mertens", p. 176; "Robert", p. 223; "Robert Mertens", p. 223). He postulated Mertensian mimicry. Mertens was born in Saint Petersburg, Russia. He moved to Germany in 1912, where he earned a doctorate in zoology from the University of Leipzig in 1915. During World War I he served in the German army. Mertens worked at the Senckenberg Museum in Frankfurt for many years, beginning as an assistant in 1919, and retiring as director emeritus in 1960. He also became a lecturer at Goethe University Frankfurt in 1932, and became a Professor there in 1939. Both jobs provided him with ample time for extensive travel and the study of lizards. He collected specimens in 30 countries. During World War II, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diurnal Animal
Diurnality is a form of plant and 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 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 preferred pollinators a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics ( morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Madagascar (the fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is endemic. Human settlement of Madagascar occurred during or before the mid first millennium AD by Austronesian peoples, presumably arriving on outrigger cano ...

Phelsuma
''Phelsuma'' is a large genus of geckos in the family Gekkonidae. Species in the genus ''Phelsuma'' are commonly referred to as day geckos. Some day geckos are seriously endangered and some are common, but all ''Phelsuma'' species are CITES Appendix II listed. Little is known about trade in day geckos, but the IUCN considers it a threat to some species. Some species are captive-bred. Taxonomy The genus itself is thought to have originated anywhere between the Late Cretaceous to the mid-Eocene (43 to 75 mya), as that is when its lineage is known to have diverged from the one containing the Namaqua day gecko (''Rhoptropella''), although it is unknown how closely related both genera are. The crown group containing all recent species is thought to have originated in the early Oligocene, about 30 million years ago, with the most basal of them being the isolated Andaman day gecko (''P. andamanensis''), which diverged from all other species shortly after the crown group originated. ...

Reptiles Of Madagascar
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 arou ...

Taxa Named By Robert Mertens
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
