Ribes
''Ribes'' is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The various species are known as currants or gooseberries, and some are cultivated for their edible fruit or as ornamental plants. ''Ribes'' is the only genus in the family Grossulariaceae. Description ''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The sepals of the flowers are larger than the petals, and fuse into a tube or saucer shape. The ovary is inferior, maturing into a berry with many seeds. Taxonomy ''Ribes'' is the single genus in the Saxifragales family Grossulariaceae. Although once included in the broader circumscription of Saxifragaceae ''sensu lato'', it is now positioned as a sister group to Saxifragaceae ''sensu stricto''. Subdivision First treated on a worldwide basis in 1907, the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Gallinule
The common gallinule (''Gallinula galeata'') is a bird in the family Rallidae. It was split from the common moorhen by the American Ornithologists' Union in July 2011. It lives around well-vegetated marshes, ponds, canals, and other wetlands in the Americas. The species is not found in the polar regions or many tropical rainforests. Elsewhere, the common gallinule is likely the most commonly seen rail species in much of North America, except for the American coot in some regions. Description and ecology The gallinule has dark plumage apart from the white undertail, yellow legs and a red frontal shield. The young are browner and lack the red shield. It has a wide range of gargling calls and will emit loud hisses when threatened. Measurements: * Length: 12.6–13.8 in (32–35 cm) * Weight: 10.9–16.1 oz (310–456 g) * Wingspan: 21.3–24.4 in (54–62 cm) This is a common breeding bird in marsh environments and well-vegetated lakes. Populations in areas where the waters freeze ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puna Teal
The Puna teal (''Spatula puna'') is a species of dabbling duck in the family Anatidae. It was at one time regarded as a subspecies of the silver teal. The Puna teal is resident in the Andes of Peru, western Bolivia, northern Chile, and extreme northwestern Argentina.Clements, J. (2007) It is found on the larger lakes and pools in the altiplano. The status of the Puna teal is Least Concern, as listed on the IUCN Red List. Taxonomy The first formal description of the Puna teal was by the Swiss naturalist Johann Jakob von Tschudi in 1844 under the binomial name ''Anas puna''. It was at one time considered as a subspecies of the silver teal in the genus ''Anas''. A molecular phylogentic study comparing mitochondrial DNA sequences published in 2009 found that the genus ''Anas'', as then defined, was non-monophyletic. The genus was subsequently split into four monophyletic genera with ten species including the Puna teal moved into the resurrected genus ''Spatula''. This genus had be ...

Junin Crake
The Junin crake or Junin rail (''Laterallus jamaicensis tuerosi'') is a species of bird in the family Rallidae. It is usually considered a subspecies of the black rail. The Junín rail is, as suggested by its common name, endemic to marshy habitats around Lake Junín Lake Junin (; Spanish ''Lago Junín'', named after the nearby town of Junin) or Chinchaycocha (possibly from Quechua ''chincha, chinchay'' north, northern, ''chinchay'' ocelot, ''qucha'' lake, lagoon, "northern lake" or "ocelot lake") is the larg ... in west-central Peru. It is threatened by habitat loss. The Junin flightless grebe, another highly endangered species, is restricted to the same lake. References External linksBirdLife Species Factsheet.

Potamogeton
''Potamogeton'' is a genus of aquatic, mostly freshwater, plants of the family Potamogetonaceae. Most are known by the common name pondweed, although many unrelated plants may be called pondweed, such as Canadian pondweed (''Elodea canadensis''). The genus name means "river neighbor", originating from the Greek ''potamos'' (river) and ''geiton'' (neighbor). Morphology ''Potamogeton'' species range from large (stems of 6 m or more) to very small (less than 10 cm). Height is strongly influenced by environmental conditions, particularly water depth. All species are technically perennial, but some species disintegrate in autumn to a large number of asexually produced resting buds called turions, which serve both as a means of overwintering and dispersal. Turions may be borne on the rhizome, on the stem, or on stolons from the rhizome. Most species, however, persist by perennial creeping rhizomes. In some cases the turions are the only means to differentiate species. The leav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chara (alga)
''Chara'' is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures. They are found in freshwater, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom. They prefer less oxygenated and hard water and are not found in waters where mosquito larvae are present. They are covered with calcium carbonate deposits and are commonly known as stoneworts. Cyanobacteria have been found growing as epiphytes on the surfaces of ''Chara'', where they may be involved in fixing nitrogen, which is important to plant nutrition. Structure The branching system of ''Chara'' species is complex with branches derived from apical cells which cut off segments at the base to form nodal and internodal cells alternately.Round, F.E. 1965.''The Biology of the algae.'' Ernest Arnold. The main axes bear whorls of branches in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myriophyllum
''Myriophyllum'' (water milfoil) is a genus of about 69 species of freshwater aquatic plants, with a cosmopolitan distribution. The center of diversity for ''Myriophyllum'' is Australia with 43 recognized species (37 endemic). These submersed aquatic plants are perhaps most commonly recognized for having elongate stems with air canals and whorled leaves that are finely, pinnately divided, but there are many exceptions. For example, the North American species ''M''. ''tenellum'' has alternately arranged scale like leaves, while many Australian species have small alternate or opposite leaves that lack dissection. The plants are usually heterophyllous, leaves above the water are often stiffer and smaller than the submerged leaves on the same plant and can lack dissection. Species can be monoecious or dioecious. In monoecious species plants are hermaphrodite, in dioecious species plants are either male or female, the flowers are small, 4(2)-parted and usually borne in emergent leaf ax ...

Juncus
''Juncus'' is a genus of monocotyledonous flowering plants, commonly known as rushes. It is the largest genus in the family Juncaceae, containing around 300 species. Description Rushes of the genus ''Juncus'' are herbaceous plants that superficially resemble grasses or sedges. They have historically received little attention from botanists; in his 1819 monograph, James Ebenezer Bicheno described the genus as "obscure and uninviting". The form of the flower differentiates rushes from grasses or sedges. The flowers of ''Juncus'' comprise five whorls of floral parts: three sepals, three petals (or, taken together, six tepals), two to six stamens (in two whorls) and a stigma with three lobes. The stems are round in cross-section, unlike those of sedges, which are typically somewhat triangular in cross-section. In ''Juncus'' section ''Juncotypus'' (formerly called ''Juncus'' subg. ''Genuini''), which contains some of the most widespread and familiar species, the leaves are reduced t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elodea
''Elodea'' is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog’s-bit family (Hydrocharitaceae), ''Elodea'' is native to the Americas and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water. An older name for this genus is ''Anacharis'', which serves as a common name in North America. The introduction of some species of ''Elodea'' into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem and it is now considered a noxious weed in these areas. ''Elodea canadensis'', sometimes called American or Canadian water weed or pond weed, is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking plants, like Brazilian elodea (''Egeria densa'') or hydrilla (''Hydrilla verticillata''). American water weed is an attractive aquarium plant and is a good ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schoenoplectus Californicus
''Schoeneoplectus californicus'' is a species of sedge known by the common names California bulrush, southern bulrush and giant bulrush. It is also sometimes called "tule", but the closely related ''Schoenoplectus acutus'' is the species most often referred to by that name. Description ''Schoenoplectus californicus'' is a rhizomed water plant found in marshy areas. It is native to the southern and western United States as well as Mexico, Central America, South America, Easter Island, and the Falkland Islands. It is naturalized on some Pacific islands including New Zealand, Hawaii and the Cook Islands. It has tall, thin, dark green stems which are usually triangular in cross-section and woolly, bristly tan or brown flowers in panicle inflorescences. Uses A notable subspecies is the totora, ''Schoenoplectus californicus'' subsp. ''tatora''. This is famous for making up the floating islands on which the Uros people of Lake Titicaca dwell, as well as occurring on isolated Eas ...
