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 admi ...

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, ... [...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 pollinator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), 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 as 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 name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

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. 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 brille. 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 lick their own brilles whe ...

Madagascar
Madagascar, officially the Republic of Madagascar, is an island country that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's List of islands by area, fourth largest island, the List of island countries, second-largest island country, and the List of countries and dependencies by area, 46th largest country overall. Its capital and List of cities in Madagascar, largest city is Antananarivo. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic period, around 180 million years ago, and separated from the Indian subcontinent approximately 90 million years ago. This isolation allowed native plants and animals to evolve in relative seclusion; as a result, Madagascar is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of its wildlife of Madagascar, wildlife being endemic. The island has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phelsuma
''Phelsuma'' is a large genus of geckos in the Family (biology), 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, 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 a ...

Reptiles Of Madagascar
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and amniotic development. Living traditional reptiles comprise four orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia ( ), which corresponds to common usage. Modern cladistic taxonomy regards that group as paraphyletic, since genetic and paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among reptiles from an evolutionary perspective. Many cladistic systems therefore redefine Reptilia as a cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Robert Mertens
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
