Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxifragaceae
Saxifragaceae is a family of herbaceous perennial flowering plants, within the core eudicot order Saxifragales. The taxonomy of the family has been greatly revised and the scope much reduced in the era of molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus '' Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are herbaceous perennials (rarely annual or biennial), sometimes succulent or xerophytic, often with perennating rhizomes. The leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence stems. They are usually simple, rarely pinnately or palmately compound. Their margins may be entire, deeply lobed, cleft, crenate or dentate and petiolate with stipules. The infloresc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachyopini
The Brachyopini (or Chrysogastrini) is a tribe of hoverflies. Unlike many members of this family these flies are generally darker and less colourful though some genera contain species with an attractive metallic lustre e.g. ''Chrysogaster''. Some like ''Brachyopa'' are associated with sap runs where their larvae feed on decaying sap. Others are found in boggy areas where their often semiaquatic larvae feed on decaying organic matter.

Sphegina Dentata
''Sphegina dentata'' is a species of hoverfly in the family Syrphidae found in Taiwan. Etymology The name comes from Latin ‘dentata’, meaning ‘dentate’, referring to the dentate male cercus. Description In male specimens, the body length is 7.1–7.9 millimeters. The wings are 5.4–5.9 millimeters, entirely microtrichose and hyaline, with brownish stigma. The face is black, concave, strongly projected antero-ventrally, with a weakly developed frontal prominence and long pilose along the eye-margin. The gena and mouth edge are black, with a large subtriangular non-pollinose shiny area; frons and vertex black; a large trapezoidal area posterior of the lunula non-pollinose and shiny; occiput black, with light yellow pilose; antenna dark brown to black with black setae dorsally on scape and pedicel, basal flagellomere round; arista only basally short and pilose, slightly more than three times as long as the basal flagellomere. The thorax is black; scutellum black, semicirc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xiangyang
Xiangyang is a prefecture-level city in northwestern Hubei province, China and the second largest city in Hubei by population. It was known as Xiangfan from 1950 to 2010. The Han River runs through Xiangyang's centre and divides the city north–south. The city itself is an agglomeration of two once separate cities: Fancheng and Xiangyang (or Xiangcheng), and was known as Xiangfan before 2010. What remains of old Xiangyang is located south of the Han River and contains one of the oldest still-intact city walls in China, while Fancheng is located to the north of the Han River. Both cities served prominent historical roles in both ancient and pre-modern Chinese history. Today, the city has been a target of government and private investment as the country seeks to urbanize and develop the interior provinces. Its built-up area made up of 3 urban districts had 2,319,640 inhabitants at the 2020 census while the whole municipality contained approximately 5,260,951 people. History ...

Pinus Taiwanensis
''Pinus taiwanensis'', the Taiwan red pine, is a species of conifer in the family Pinaceae endemic to Taiwan. Taxonomy It is a close relative of ''Pinus luchuensis'' of Japan and ''P. hwangshanensis'' of China, sometimes considered as a subspecies of the former. Sometimes ''P. hwangshanensis'' from China are also referred to as ''P. taiwanensis''. ''P. taiwanensis'' var. ''fragilissima'' and ''P. taiwanensis'' var. ''taiwanensis'' are the two varieties of this species. Description The Taiwan red pine is a large tree, with a straight trunk up to tall and in diameter. Needles are in bundles of two. Cones are long. It is a common species in the Central Mountain Range The Central Mountain Range is the principal mountain range on the island of Taiwan. It runs from the north of the island to the south. Due to this separation, connecting between the west and east is not very convenient.

Astilbe
''Astilbe'' is a genus of 18 species of rhizomatous flowering plants within the family Saxifragaceae, native to mountain ravines and woodlands in Asia and North America. Some species are known by the common names false goat's beard and false spirea. These hardy herbaceous perennials are cultivated by gardeners for their large, handsome, often fern-like foliage and dense, feathery plumes of flowers. They are widely adapted to shade and water-logged conditions, hence they are particularly associated with pond-side planting. They also tolerate clay soils well. Numerous hybrid cultivars have been raised. Flowers of at least some ''Astilbe'' species have a strong and pleasant aroma. Some species, including '' Astilbe rivularis'', are used in traditional medicine. Species Species of ''Astilbe'' include: *'' Astilbe biternata'' (Vent.) Britton ex Kearney – Appalachian false goat's beard *''Astilbe chinensis'' (Maxim.) Franch. & Sav. *''Astilbe crispa'' (Arends) Bergmans *'' Astilbe ...

Hoverfly
Hover flies, also called flower flies or syrphid flies, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers; the adults of many species feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In some species, the larvae are saprotrophs, eating decaying plant and animal matter in the soil or in ponds and streams. In other species, the larvae are insectivores and prey on aphids, thrips, and other plant-sucking insects. Insects such as aphids are considered a crop pest, and therefore the aphid-eating larvae of some hover flies serve as an economically (as well as ecologically) important predator and even potential agents for use in biological control, while the adults may be pollinators. About 6,000 species in 200 genera have been described. Hover flies are common throughout the world and can be found on all continents except Antarctica. Hover flies are harmless to most mammals, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerat ...
