Cotton Pygmy Goose
The cotton pygmy goose or cotton teal (''Nettapus coromandelianus'') is a small perching duck which breeds in Asia, Southeast Asia extending south and east to Queensland where they are sometimes called white-quilled pygmy goose. They are among the smallest waterfowl in the world and are found in small to large waterbodies with good aquatic vegetation. They are usually seen in pairs or larger groups of pairs, roosting and nesting on trees near water. They are strong fliers and are known to disperse widely, especially in winter. Their breeding season coincides with the rains. Taxonomy The cotton pygmy goose was Species description, formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the ducks, swans and geese in the genus ''Anas'' and coined the binomial nomenclature, binomial name ''Anas coromandeliana''. Gmelin based his description on "La Sarcelle de Coromandel" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Friedrich Gmelin
Johann Friedrich Gmelin (8 August 1748 – 1 November 1804) was a German natural history, naturalist, chemist, botanist, entomologist, herpetologist, and malacologist.

Nominate Subspecies
In 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), 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 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.

Ruppia
''Ruppia'', also known as the widgeonweeds, ditch grasses or widgeon grass, is the only extant genus in the family Ruppiaceae, with 11 known species. These are aquatic plants widespread over much of the world. The genus name honours Heinrich Bernhard Rupp, a German botanist (1688–1719). They are widespread outside of frigid zones and the tropics. Description The leaf is simple and not rhizomatous. They can be annual (commonly) or perennial (rarely); stem growth is conspicuously sympodial, but sometimes is not. These species are adapted to be in brackish water (and salt marshes). The leaves are small or medium-sized. Their disposition can be alternate, opposite, or whorled (usually alternate except when subtending an inflorescence). Even, lamina keep entire and are setaceous or linear. The leaf just shows one vein without cross-venules. Stomata are not present. The mesophyll leaks calcium oxalate crystals. The minor leaf veins do not present phloem transfer cells and leaks ves ...

Hydrilla
''Hydrilla'' (waterthyme) is a genus of aquatic plant, usually treated as containing just one species, ''Hydrilla verticillata'', though some botanists divide it into several species.

The leaves are arranged in whorls of two to eight around the stem, each leaf 5–20 mm long and 0.7–2 mm broad, with serrations or small spines along the leaf margins; the leaf midrib is often reddish when fresh. It is monoecious (sometimes dioecious), with male and female flowers produced separately on a single plant; the flowers are small, with three sepals and three petals, the petals 3–5 mm long, transparent with red streaks. It reproduces primarily vegetatively by fragmentation and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ipomoea
''Ipomoea'' () is the largest genus in the plant family Convolvulaceae, with over 600 species. It is a large and diverse group, with common names including morning glory, Ipomoea aquatica, water convolvulus or water spinach, sweet potato, bindweed, Ipomoea alba, moonflower, etc. The genus occurs throughout the tropical and subtropical regions of the world, and comprises annual plant, annual and perennial plant, perennial herbaceous plants, lianas, shrubs, and small trees; most of the species are twining Vine, climbing plants. Their most widespread common name is morning glory, but some species in related genera bear that same common name and some ''Ipomoea'' species are known by different common names. Those formerly separated in ''Calonyction'' (Ancient Greek, Greek "good" and , , , "night") are called moonflowers. The name ''Ipomoea'' is derived from the Ancient Greek , meaning , and (), meaning "resembling". It refers to their twining habit. Uses and ecology Human ...

Oryzias
''Oryzias'' is a genus of ricefishes native to fresh and brackish water in east and south Asia. Some species are widespread and the Japanese rice fish (''O. latipes'') is commonly used in science as a model organism, while others have very small ranges and are threatened. They are small, up to long, and most are relatively plain in colour. The genus name ''Oryzias'' is a reference to the scientific name for rice, ''Oryza''. They have an unusual reproductive behavior where the female facultatively (optionally) carries the eggs in a cluster at the pelvic or anal fins for a period after they have been fertilized.

Chilika Lake
Chilika Lake is the largest brackish water lagoon with estuarine character that sprawls along the east coast of Indian sub-continent in Asia and second largest coastal lagoon in the world, covering an area of over . It is spread over the Puri, Khordha and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal. It has been listed as a tentative UNESCO World Heritage site. Its salinity varies by region, from freshwater where rivers flow in, to oceanic salinity levels due to tidal influx. History Geological evidence indicates that Chilika Lake was part of the Bay of Bengal during the later stages of the Pleistocene period (1.8 million to 10,000 years BP). Excavations were conducted by the Archaeological Survey of India at Golabai Sasan (), north of Chilika lake in Khurdha district. Golabai provides evidence of a sequence of Chilika area culture in three phases: Neolithic (c. 1600 BCE), Chalcolithic (c. 14 ...

Nettapus Coromandelianus Female - Bueng Boraphet
Pygmy geese are a group of very small "perching ducks" in the genus ''Nettapus'' which breed in the Old World tropics. They are the smallest of all wildfowl. As the "perching ducks" are a paraphyletic group, they need to be placed elsewhere. The initially assumed relationship with the dabbling duck subfamily Anatinae has been questioned, and it appears they form a lineage in an ancient Gondwanan radiation of waterfowl, within which they are of unclear affinities. An undescribed fossil species from the late Hemphillian (5.0–4.1 mya) of Jalisco, central Mexico, has also been identified from the distal end of a tarsometatarsus. It is only record of the genus in the New World. The genus ''Nettapus'' was erected by the German naturalist Johann Friedrich von Brandt in 1836. The name is from Ancient Greek ''nētta'' meaning "duck" and ''pous'' meaning "foot". It was thought that the type species, the African pygmy goose (''Nettapus auritus''), possessed the feet and body of a duck and ...
