Paroedura Neglecta
''Paroedura neglecta'' is a species of lizard in the family Gekkonidae. It was first discovered in 2006, but the species was not named until 2019, hence the specific name meaning "neglected". It is endemic to Tsingy de Bemaraha National Park in northwestern Madagascar. Taxonomy The holotype specimen of ''Paroedura neglecta'' is an adult male collected on 1 April 2006 from Andafiabe at the Beboka River, in the Melaky region of western Madagascar. Although the specimen was recognized as an unnamed species shortly after its discovery, it was not species description, described until 13 years later in May 2019, thus it was given the specific name ''neglecta'' (Latin for "neglected"). Genetic analysis has found that ''Paroedura neglecta'' is a member of the ''Paroedura bastardi'' clade, and is a sister taxon to ''Paroedura tanjaka''. The following cladogram shows the position of ''P. neglecta'' among its closest relatives according to Piccoli ''et al.'' (2023): Distribution and habi ...

Paroedura Rennerae
''Paroedura rennerae'' is a species of lizards in the family of the Gekkonidae. Members of this species were formerly assigned to ''Paroedura bastardi'', but a study in 2021 found that they represent a separate species within the species complex. It is Endemism, endemic to Madagascar, where it occurs in a variety of habitats. Taxonomy Specimens of ''Paroedura rennerae'' were not originally recognized as a separate species from Mocquard's Madagascar ground gecko, with collected specimens labelled as ''P. bastardi'' or ''P.'' sp. aff. ''bastardi''. It was not until 2021 that an integrative revision of the ''P. bastardi'' species complex found that ''P. rennerae'' represents a morphologically and genetically distinct species. An adult female collected on 2 December 2010 from Kirindy Forest, Kirindy Reserve was designated as the holotype specimen of ''P. rennerae''. The specific name honors botanist and biologist Susanne Renner. The following cladogram shows the position of ''P. re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris (anatomy)
In humans and most mammals and birds, the iris (plural: ''irides'' or ''irises'') is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. Eye color is defined by the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm. Structure The iris consists of two layers: the front pigmented fibrovascular layer known as a stroma and, beneath the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles ( dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. The sphincter pupillae is the opposing muscle of the dilator pupillae. The pupil's diameter, and thus the inner border of the iris, changes size when constricting or dilating. The outer border of the iris does not change size. The constricti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rostral Scale
The rostral scale, or rostral, in snakes and other scaled reptiles is the median plate on the tip of the snout that borders the mouth opening. Wright AH, Wright AA (1957). ''Handbook of Snakes of the United States and Canada''. Ithaca and London: Comstock Publishing Associates. (7th printing, 1985). 1,105 pp. (in two volumes). . It corresponds to the mental scale in the lower jaw. The term pertains to the rostrum, or nose. In snakes, the shape and size of this scale is one of many characteristics used to differentiate species from one another. Related scales *Nasorostral scale *Mental scale *Labial scales See also *Snake scales *Anatomical terms of location Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans.

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.

Paroedura Karstophila
''Paroedura karstophila'' is a species of lizard in the family Gekkonidae. It is described from Montagne des Français, a karstic limestone massif in the far north of Madagascar recently established as nature reserve. The new species has the nostril in contact with the rostral scale and shares many characters with P. karstophila and especially with P. homalorhina which are also restricted to karstic habitats. Paroedura hordiesi differs from P. karstophila by a smoother skin on dorsum and legs, by original and regenerated tails being both entirely smooth, by colouration, and by larger snout-vent length. Morphologically the new species is most similar to P. homalorhina from the Ankarana reserve from which it can be distinguished by shorter limbs and a less slender habitus. Published molecular data place the new species as close relative of P. homalorhina and another undescribed species from Nosy Hara Island, while newly determined data of the cox1 gene for P. karstophila c ...

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do no ...

Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Forests
The tropical and subtropical dry broadleaf forest is a habitat type defined by the World Wide Fund for Nature and is located at tropical and subtropical latitudes. Though these forests occur in climates that are warm year-round, and may receive several hundred centimeters of rain per year, they have long dry seasons that last several months and vary with geographic location. These seasonal droughts have great impact on all living things in the forest. Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
