Central Andean Wet Puna
The Central Andean wet puna is a montane grasslands and shrublands ecoregion in the Andes of Peru and Bolivia. Setting This ecoregion occurs above and consists of high-elevation, wet, montane grasslands amid lakes, plateaus, valleys, and high mountains. It is bordered on the west by the Sechura Desert and on the east by the Peruvian Yungas. To the north it transitions to the Cordillera Central páramo, to the south, the Central Andean puna. The ecoregion can be subdivided into three subregions: the high andean puna, wet puna, and wet montane grassland. The high Andean puna lies between . Nightly freezes occur throughout the year and annual precipitation is less than , falling mainly as snow and hail. The wet puna is located in the altiplano at elevations between . It is wetter in the north, where the wet season lasts eight months, and drier in the south, where the wet season lasts two months. Precipitation ranges from per year. Night freezes occur from March to October. The w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huascarán National Park
Huascarán National Park () is a Peruvian national park that comprises most of the mountain range known as Cordillera Blanca (the world's highest tropical mountain range) which is part of the central Andes, in the region of Ancash. The park covers an area of and is managed by the Peruvian Network of Protected Natural Areas, or SERNANP (Servicio Nacional de Áreas Naturales Protegidas). It was designated as a World Heritage Site in 1985 by UNESCO, is also a well-known mountaineering spot, and harbors a unique biodiversity with plant species such as the Queen of the Andes, trees of the genera '' Polylepis'' and ''Buddleja'', and animals such as spectacled bears, condors, vicunas, and tarucas. The park is approximately long from north to south and averages about in width. The western slope of the Cordillera Blanca drains to the Pacific Ocean via the Santa River and the eastern slopes drain to the Marañón River and ultimately to the Amazon River and the Atlantic Ocean. ...

Subtropical Highland Climate
An oceanic climate, also known as a marine climate or maritime climate, is the temperate climate sub-type in Köppen classification represented as ''Cfb'', typical of west coasts in higher middle latitudes of continents, generally featuring cool to warm summers and cool to mild winters (for their latitude), with a relatively narrow annual temperature range and few extremes of temperature. Oceanic climates can be found in both hemispheres generally between 40 and 60 degrees latitude, with subpolar versions extending to 70 degrees latitude in some coastal areas. Other varieties of climates usually classified together with these include subtropical highland climates, represented as ''Cwb'' or ''Cfb'', and subpolar oceanic or cold subtropical highland climates, represented as ''Cfc'' or ''Cwc''. Subtropical highland climates occur in some mountainous parts of the subtropics or tropics, some of which have monsoon influence, while their cold variants and subpolar oceanic climates occ ...

Daucus
''Daucus'' is a worldwide genus of herbaceous plants of the celery family Apiaceae of which the best-known species is the cultivated carrot. ''Daucus'' has about 45 species. The oldest carrot fossil is 1.3 Ma, and was found on the island of Madeira in the Atlantic Ocean. Description Members of ''Daucus'' are distinguished within the family ''Apiaceae'' by their leaves which are 2–3 pinnatisect with narrow end sections. The genus primarily consists of biennial plants but also includes some annual plants and some perennial herbs. All ''Daucus'' have bristly stems. The inflorescences are umbels. The flowers are mostly white, with bracts and bracteoles. The petals may be pure white, reddish, pinkish or yellowish. They are emarginate above and have pointed, wrapped lobules. The petals are often unequal in size, with petals at the outermost edge of the inflorescence often being larger. The fruit is an ovoid to ellipsoidal schizocarp, cylindrical or compressed, with ciliate pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baccharis
''Baccharis'' is a genus of perennial plant, perennials and shrubs in the Asteraceae, aster family (Asteraceae). They are commonly known as baccharises but sometimes referred to as "brooms", because many members have small thin leaves resembling the true broom (shrub), brooms. They are not at all related to these however, but belong to an entirely different lineage of eudicots. ''Baccharis halimifolia, B. halimifolia'' is commonly known as "groundsel bush", however true groundsels are found in the genus ''Senecio''. ''Baccharis'', with over 500 species, is one of the largest genera in the Asteraceae. It is found throughout the Americas, distributed mainly in the warmer regions of Brazil, Argentina, Colombia, Chile and Mexico, with ''B. halimifolia'' ranging northward along the Atlantic Coast to the southern tip of Nova Scotia in Canada. If present, the leaves of ''Baccharis'' are borne along the stems in alternate fashion. Flowers are usually white or pinkish. There are no ray f ...

Asteraceae
Asteraceae () is a large family (biology), family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the Order (biology), order Asterales. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of Extant taxon, extant species in each family is unknown. The Asteraceae were first described in the year 1740 and given the original name Composita, Compositae. The family is commonly known as the aster, Daisy (flower), daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be Annual plant, annual, Biennial plant, biennial, or Perennial plant, perennial, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions, in a wide variety of habitats. Most occur in Hot desert climate, hot desert and cold or hot Semi-arid climate, semi-desert climates, and they are found on ever ...

Cortaderia
''Cortaderia'' is a genus of plants in the Poaceae or grass family of plants. All current species included in the ''Cortaderia'' genus are native to South and Central America, ranging from the Patagonia region of southern Chile and Argentina, to Costa Rica. For many years, five species native to New Zealand were included in the genus, but since 2011 these have been since reclassified into the genus '' Austroderia'' containing only species native to New Zealand. Etymology The common name pampas grass, though strictly referring to ''C. selloana'', is frequently applied to all species in the genus, as well as the five former members reclassied into the genus Austroderia (sometimes also to species of '' Erianthus'' and '' Saccharum ravennae''). The name of the genus is derived from the Argentine Spanish word ''cortadera'', which in turn refers to the sharp serrations on the leaves. '' Cortaderia jubata'' and '' C. rudiuscula'' produce copious seed asexually. Description Cortaderi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chusquea
''Chusquea'' is a genus of evergreen bamboos in the grass family. Most of them are native to mountain habitats in Latin America, from Mexico to southern Chile and Argentina. They are sometimes referred to as South American mountain bamboos. Unlike most other grasses, the stems of these species are solid, not hollow. Some animals are, to various extents, associated with stands of ''Chusquea'', for example the Inca wren, monito del monte, and the plushcap. Notable species '' Chusquea culeou'', the Chilean feather bamboo or colihue cane, from southern Chile and adjacent western Argentina, is notable as the most frost-tolerant South American bamboo and the only one that has been grown successfully to any extent in the temperate Northern Hemisphere, with successful growth as an ornamental plant north to Scotland. The colihue cane was used by the Mapuches Indians to make instruments and as lances during the War of Arauco. ''Chusquea quila'' (in Spanish ''quila''), in contrast to ...

Stipa
''Stipa'' is a genus of 141 species of large Perennial plant, perennial hermaphrodite, hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the ...

Paspalum
''Paspalum'' is a genus of plants in the grass family. The group is widespread across much of Asia, Africa, Australia, and the Americas. Commonly known as paspalum, bahiagrasses, crowngrasses or dallis grasses, many of the species are tall perennial New World grasses. They are warm-season C4 grasses and are most diverse in subtropical and tropical regions. '' Paspalum scrobiculatum'' (''koda'', ''varuka'', ''varuku'', etc.) is a millet locally grown as food grain. Some species, such as bahiagrass (''P. notatum'') and '' P. nicorae'', are grown for pasturage, especially with the perennial forage peanut (''Arachis glabrata'') as a companion crop. Bahiagrass has also some significance as a honey plant. Water finger-grass (''P. vaginatum'') resembles bermudagrass (''Cynodon dactylon''), but has a higher salinity tolerance and can consume greywater. It is not infrequently used for arena and golf course turf in warmer coastal regions, such as Baja California, Florida, Peru, T ...

Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus '' Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640. Fescue pollen is a significant contributor to hay fever. Taxonomy The genus ''Festuca'' represents a major evolutionary line of ...

Calamagrostis
''Calamagrostis'' (reed grass or smallweed) is a genus of flowering plants in the grass family Poaceae, with about 260 species that occur mainly in temperate regions of the globe. Towards equatorial latitudes, species of ''Calamagrostis'' generally occur at higher elevations. These tufted perennials usually have hairless narrow leaves. The ligules are usually blunt. The inflorescence forms a panicle. Some may be reed-like. The plants may be rhizomatous (underground stems with shoots), stoloniferous (with runners), or caespitose (growing in tufts or clumps). The bisexual spikelets have a single floret and generally they are purple or purple-brown. The spikelets are clustered into inflorescences, which usually develop in early- to mid-summer on long culms ( = stems). Many species of ''Calamagrostis'' are morphologically similar, but they generally occur in distinct habitats, and they have unique geographical distributions. Given the subtle distinctions between many closely related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
