Dry Pampas
The Semi-arid Pampas, also known as the Dry Pampas, is a temperate grasslands, savannas, and shrublands, temperate grassland terrestrial ecoregion, ecoregion of south central Argentina. Setting The Semi-arid Pampas cover an area of , including western Buenos Aires Province, southern Cordoba Province, Argentina, Cordoba and San Luis Province, San Luis Provinces and most of La Pampa Province. The area is, in all, home to no more than a million people, who generally enjoy some of the nation's lowest poverty rates. The Humid Pampas grassland lies to the east, while the drier Argentine Espinál (thorny) grassland lies to the west. The soil tends to be sandier in this region than to the east, though both regions are characterized by their mostly minimal incline and frequent finger lakes. Generally more similar than not, these two biomes are mostly distinguished by their contrasting rainfall quantities, soil quality and land use; this section of the pampas typically sees about a third le ...

Arid Pampas Red
Aridity is the condition of geographical regions which make up approximately 43% of total global available land area, characterized by low annual precipitation, increased temperatures, and limited water availability.Perez-Aguilar, L. Y., Plata-Rocha, W., Monjardin-Armenta, S. A., Franco-Ochoa, C., & Zambrano-Medina, Y. G. (2021). The Identification and Classification of Arid Zones through Multicriteria Evaluation and Geographic Information Systems—Case Study: Arid Regions of Northwest Mexico. ''ISPRS International Journal of Geo-Information'', ''10''(11), 720. https://doi.org/10.3390/ijgi10110720 These areas tend to fall upon degraded soils, and their health and functioning are key necessities of regulating ecosystems’ atmospheric components. Change over time The distribution of aridity at any time is largely the result of the general circulation of the atmosphere. The latter does change significantly over time through climate change. For example, temperature increase by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Cypress
''Cupressus sempervirens'', the Mediterranean cypress (also known as Italian cypress, Tuscan cypress, Persian cypress, or pencil pine), is a species of Cupressus, cypress native plant, native to the eastern Mediterranean region and Iran. While some studies show it has modern medicinal properties, it is most noted for uses in folk medicine, where the dried leaves of the plant are used to treat various ailments. It is well-adapted to the environmental conditions that it lives in due to its ability to survive in both Acidic soil, acidic and Alkali soil, alkaline soils and withstand drought. ''Cupressus sempervirens'' is widely present in culture, most notably in Iran, where it is both a sacred tree and a metaphor for "the graceful figure of the beloved". Description ''Cupressus sempervirens'' is a medium-sized Pinophyta, coniferous evergreen tree growing up to 35 m (115 ft) tall, with a conic crown with level branches and variably loosely hanging branchlets. It is very lon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stork
Storks are large, long-legged, long-necked wading birds with long, stout bills. They belong to the family Ciconiidae, and make up the order Ciconiiformes . Ciconiiformes previously included a number of other families, such as herons and ibises, but those families have been moved to other orders. Storks dwell in many regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are 20 living species of storks in six genera. Various terms are used to refer to groups of storks, two frequently used ones being a ''muster'' of storks and a ''phalanx'' of storks. Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Ottomar Ansch� ...

Coot
Coots are medium-sized water birds that are members of the rail family, Rallidae. They constitute the genus ''Fulica'', the name being the Latin term for "coot". Coots have predominantly black plumage, and—unlike many rails—they are usually easy to see, often swimming in open water. Taxonomy and systematics The genus ''Fulica'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. The genus name is the Latin word for a Eurasian coot. The name was used by the Swiss naturalist Conrad Gessner in 1555. The type species is the Eurasian coot. A group of coots is referred to as a ''covert'' or ''cover''. Species The genus contains 10 extant species and one which is now extinct. Extinct species Recently extinct species * ''Fulica newtonii'' Milne-Edwards, 1867 – Mascarene coot (extinct, c. 1700) Late Quaternary species * ''Fulica chathamensis'' Forbes, 1892 – Chatham Island coot ( early Holocene of the ...

Martin (bird)
The swallows, martins, and saw-wings, or Hirundinidae are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used as the common name for '' Hirundo rustica'' in the UK and Ireland. Around 90 species of Hirundinidae are known, divided into 21 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory. This family comprises two subfamilies: Pseudochelidoninae (the river martins of the genus ''Pseudochelidon'') and Hirundininae (all other swallows, martins, and saw-wings). In the Old World, the name "martin" tends to be used for the squarer-tailed species, and the name "swallow" for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partridge
A partridge is a medium-sized Galliformes, galliform bird in any of several genera, with a wide Indigenous (ecology), native distribution throughout parts of Europe, Asia and Africa. Several species have been introduced to the Americas. They are sometimes grouped in the Perdicinae subfamily of the Phasianidae (pheasants, quail, etc.). However, molecular research suggests that partridges are not a distinct taxon within the family Phasianidae, but that some species are closer to the pheasants, while others are closer to the junglefowl. Description Partridges are medium-sized Game (hunting), game birds, generally intermediate in size between the larger pheasants, smaller quail; they're ground-dwelling birds that feature variable plumage colouration across species, with most tending to grey and brown. Range and habitat Partridges are native to Europe, Asia, Africa, and the Middle East. Some species are found nesting on steppes or agricultural land, while other species prefer mor ...

Gray Hawk
The gray hawk (''Buteo plagiatus'') or Mexican goshawk is a smallish raptor found in open country and forest edges. It is sometimes placed in the genus ''Asturina'' as ''Asturina plagiata''. The species was split by the American Ornithological Society (AOU) from the gray-lined hawk. The gray hawk is found from Costa Rica north into the southwestern United States. The gray hawk is in length and weighs on average. The adult has a pale gray body, the tail is black with three white bands and the legs are orange. It is a solid, unpatterned gray on the upper parts. Immature birds have dark brown upperparts, a pale-banded brown tail, brown-spotted white underparts and a brown streaked buff head and neck. This species is quite short-winged, and has a fast agile flight for a ''Buteo''. The call is a shrill whistled ''kleee-ooo''. The gray hawk feeds mainly on lizards and snakes, but will also take small mammals, birds and frogs. It usually sits on an open high perch from which it swo ...

Pampas Deer
The Pampas deer (''Ozotoceros bezoarticus'') is a species of deer that live in the grasslands of South America at low elevations.Geist, Valerius. Deer of the world their evolution, behaviour, and ecology'. Mechanicsburg, Pa: Stackpole Books, 1998 They are known as in Portuguese and as or in Spanish. It is the only species in the genus ''Ozotoceros''. Their habitat includes water and hills, often with winter drought, and grass that is high enough to cover a standing deer.P., Walker, Ernest. ''Walker's Mammals of the world''. Baltimore: Johns Hopkins UP, 1991 Many of them live on the Pantanal wetlands, where there are ongoing conservation efforts, and other areas of annual flooding cycles. Human activity has changed much of the original landscape. They are known to live up to 12 years in the wild, longer if captive, but are threatened due to over-hunting and habitat loss. Many people are concerned over this loss, because a healthy deer population means a healthy grassland, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conquest Of The Desert
The Conquest of the Desert () was an Armed Forces of the Argentine Republic, Argentine military campaign directed mainly by General Julio Argentino Roca during the 1870s and 1880s with the intention of establishing dominance over Patagonia, inhabited primarily by Indigenous peoples in Argentina, Indigenous peoples. The Conquest of the Desert extended Argentine territories into Patagonia and ended Chilean expansion in the region. Argentine troops killed more than 1,000 Mapuches, displaced more than 15,000 more from their traditional lands and enslaved a portion of the remaining Indigenous people. Argentines of European descent, Settlers of European descent moved in and developed the lands through irrigation for agriculture, converting the territory into an extremely productive area that contributed to the status of Argentina as a great exporter of agricultural products during the early 20th century.''The Argentine Military and the Boundary Dispute With Chile, 1870-1902,'' George ...

Puelche People
The Gününa küna (Guennakin), or sometimes Puelche (Mapudungun: ''pwelche'', "people of the east") were Indigenous peoples living east of the Andes Mountains in Chile and Southwest Argentina. They were annihilated by Plague (disease), plagues and epidemics in the late 18th century, with survivors merging into other groups such as the Mapuche, Het people, Het, and Tehuelche people, Tehuelche. Language and name They spoke the Puelche language, which went extinct around the 1970s. Currently, there are efforts to revitalize the language. The name "Puelche" was not an autonym but was given to them by the Mapuche. Lifeways The Puelches, like the Pehuenches, were hunters, gatherers, and fishermen. They used bows, arrows, and — after the arrival of the Mapuche — spears. They were tall and stout and dressed in fur ''quillangos'' (cloaks) and turbans of rolled threads with nets that covered their heads and on which they attached feather ornaments. They build their houses wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darwin's Rhea
Darwin's rhea or the lesser rhea (''Rhea pennata'') is a large flightless bird, the smaller of the two extant species of rheas. It is found in the Altiplano and Patagonia in South America. Description The lesser rhea stands at tall. Length is and weight is . Like most ratites, it has a small head and a small bill, the latter measuring , but has long legs and a long neck. It has relatively larger wings than other ratites, enabling it to run particularly well. It can reach speeds of 60 km/h (37 mph), enabling it to outrun predators. The sharp claws on the toes are effective weapons. Their feathers are similar to those of ostriches, in that they have no aftershaft.Perrins, C. (1987) Their plumage is spotted brown and white, and the upper part of their tarsus is feathered. The tarsus is long and has 18 horizontal plates on the front. Etymology It is known as ''ñandú petiso'', or ''ñandú del norte'', in Argentina, where the majority live. Other names are ''su ...

Patagonia
Patagonia () is a geographical region that includes parts of Argentina and Chile at the southern end of South America. The region includes the southern section of the Andes mountain chain with lakes, fjords, temperate rainforests, and glaciers in the west and Patagonian Desert, deserts, Plateaus, tablelands, and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The northern limit of the region is not precisely defined; the Colorado River, Argentina, Colorado and Barrancas River, Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes considered part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía R ...
