Somatochlora Flavomaculata
''Somatochlora flavomaculata'', also called yellow-spotted emerald, is a common species of dragonfly in the family Corduliidae. Its distribution stretches from France to Siberia and Mongolia. It frequents wetlands in its range. The males are known to defend their territory. Identification Unlike other dragonflies that are metallic green, the species has yellow spots on its thorax and abdomen. Females have the largest spots, and the spots are brighter on young specimens. Spots on the abdomen become darker as an individual ages and may later become almost invisible. The species is similar to ''Somatochlora metallica'', also known as brilliant emerald, but it has more yellow on top of its abdomen with yellow going down its sides. ''S. flavomaculata'' is also smaller than ''S. metallica''. Behavior The males defend their territory on dry vegetation, paths by bushes and trees, in a reedbed's Glade (geography), glades, and waterbodies. Near the end of its breeding cycle, the waterbodie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dragonfly
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along or ...

Corduliidae
The Corduliidae, also knowns as the emeralds, emerald dragonflies or green-eyed skimmers, is a family of dragonflies. These dragonflies are usually black or dark brown with areas of metallic green or yellow, and most of them have large, emerald-green eyes. The larvae are black, hairy-looking, and usually semiaquatic. This family include species called "baskettails", "emeralds", "sundragons", "shadowdragons", and "boghaunters". They are not uncommon and are found nearly worldwide, but some individual species are quite rare. Hine's emerald dragonfly (''Somatochlora hineana''), for example, is an endangered species in the United States. Selected genera Some genera included in this family are: * '' Aeschnosoma'' * ''Antipodochlora'' – Dusk dragonfly * ''Cordulia'' – American emeralds * ''Corduliochlora'' * '' Cordulisantosia'' * ''Dorocordulia'' – little emeralds * ''Epitheca'' – baskettails * '' Guadalca'' * ''Helocordulia'' – sundragons * '' Hemicordulia'' - eme ...

Somatochlora Metallica
The brilliant emerald, ''Somatochlora metallica'', is a middle-sized species of dragonfly. It is the largest and greenest of the ''Somatochlora'' species; long. ''S. metallica'' is found across most of northern Eurasia where it is the commonest of its genus. In Great Britain, it is locally common in south east England and has a very restricted population in Scotland. The East Asian ''Somatochlora vera'', scientifically described in 1914 by Aleksandr Bartenev based on a specimen from Ussuri, Siberia Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of ... (and later also reported in northern China), is typically treated as part of ''S. metallica'', but has also been considered a synonym of the East Asian '' S. exuberata''.

Glade (geography)
In the most general sense, a glade or clearing is an open area within a forest. Glades are often grassy meadows under the canopy of deciduous trees such as red alder or quaking aspen in western North America. They also represent openings in forests where local conditions such as avalanches, poor soils, or fire damage have created semipermanent clearings. They are very important to herbivorous animals, such as deer and elk, for forage and denning activities. Sometimes the word is used in a looser sense, as in the treeless wetlands of the Everglades of Florida. In the central United States, calcareous glades occur with rocky, prairie-like habitats in areas of shallow soil. Glades are characterized by unique plant and animal communities that are adapted to harsh and dry conditions. See also *Treefall gap A treefall gap is a distinguishable hole in the canopy of a forest with vertical sides extending through all levels down to an average height of above ground. These holes o ...

Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or seawater, saltwater. The main w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species Richness
Species richness is the number of different species represented in an ecological community, landscape or region. Species richness is simply a count of species, and it does not take into account the abundances of the species or their relative abundance distributions. Species richness is sometimes considered synonymous with species diversity, but the formal metric species diversity takes into account both species richness and species evenness. Sampling considerations Depending on the purposes of quantifying species richness, the individuals can be selected in different ways. They can be, for example, trees found in an inventory plot, birds observed from a monitoring point, or beetles collected in a pitfall trap. Once the set of individuals has been defined, its species richness can be exactly quantified, provided the species-level taxonomy of the organisms of interest is well enough known. Applying different species delimitations will lead to different species richness values ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
