Buff-breasted Earthcreeper
The buff-breasted earthcreeper (''Upucerthia validirostris'') is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina, Bolivia, Chile, and Peru. Taxonomy and systematics The buff-breasted earthcreeper has three subspecies, the nominate ''U. v. validirostris'' ( Burmeister, 1861), ''U. v. saturata'' ( Carriker, 1933), and ''U. v. jelskii'' (Cabanis, 1874). Before a 2013 publication, the buff-breasted earthcreeper was credited with an additional subspecies, and ''U. v. jelskii'' was treated as a separate species, the "plain-breasted" earthcreeper, with ''U. v. saturata'' as a subspecies of it. The paper resulted in the "collapse" of the two species with five subspecies into the current one-species, three-subspecies, model.Areta, J.I. and Pearman, M. (2013).

Hermann Burmeister
Karl Hermann Konrad Burmeister (also known as Carlos Germán Conrado Burmeister) (15 January 1807 – 2 May 1892) was a German Argentine zoologist, entomologist, herpetologist, botany, botanist, and coleopterologist. He served as a professor at the Martin Luther University Halle-Wittenberg, University of Halle, headed the museum there and published the ''Handbuch der Entomologie'' (1832–1855) before moving to Argentina where he worked until his death. Career Burmeister was born in Stralsund, where his father was a customs officer. He studied medicine at University of Greifswald, Greifswald (1825–1827) and Halle (Saale), Halle (1827–1829), and in 1830 went to Humboldt University of Berlin, Berlin to qualify himself to be a teacher of natural history. His dissertation was titled ''De insectorum systemate naturali'' and graduated as a doctor of medicine on November 4, 1829 and then received a doctor of philosophy on December 19 in the same year.

Department Of Ancash
Ancash (; ) is a department and region in western Peru. It is bordered by the departments of La Libertad on the north, Huánuco and Pasco on the east, Lima on the south, and the Pacific Ocean on the west. Its capital is the city of Huaraz, and its largest city and port is Chimbote. The name of the region originates from the Quechua word ('light, of little weight'), from ('blue') or from ('eagle'). Geography Ancash is a land of contrasts: it features two great longitudinal valleys, which combine the mountain characteristics of the Callejón de Huaylas (Alley of Huaylas) with the sylvan ones of the Alto Marañón. Kilometres of sandy beaches and the blue waters of the Pacific. The territory of the coast, high plateaux and Andean '' punas'' of the department are flat, while the rest of the territory, in the Andes, is very rough. In the west, there are slopes with strong declivity form narrow canyons with abrupt and deserted sides. The rough territory of the department ...

Birds Described In 1861
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Upucerthia
''Upucerthia'' is a genus of bird in the family Furnariidae. Taxonomy and etymology ''Upucerthia'' is a genus of bird in the family Furnariidae. Established by French zoologist Isidore Geoffroy Saint-Hilaire in 1832, it contains four species known as earthcreepers. Genetic studies done in the early 2000s indicated that the genus as it stood at that time was highly polyphyletic, with species representing four distinct clades. As a result, a total of five former species were moved to other genera. The rock earthcreeper and the straight-billed earthcreeper were moved to the genus ''Ochetorhynchus''. The Bolivian earthcreeper and the Chaco earthcreeper were moved to the genus '' Tarphonomus'', and the striated earthcreeper was moved into the monotypic genus '' Geocerthia''. The genus name is a portmanteau of the genus names '' Upupa'' (for the hoopoes) and ''Certhia'' (for the treecreepers).

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change between grazing events. Successful planned grazing strategies have been in support of the American bison of the Great Plains, or migratory wildebeest of the African savannas, or by holistic planned grazing.

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

South
South is one of the cardinal directions or compass points. The direction is the opposite of north and is perpendicular to both west and east. Etymology The word ''south'' comes from Old English ''sūþ'', from earlier Proto-Germanic ''*sunþaz'' ("south"), possibly related to the same Proto-Indo-European root that the word ''sun'' derived from. Some languages describe south in the same way, from the fact that it is the direction of the sun at noon (in the Northern Hemisphere), like Latin meridies 'noon, south' (from medius 'middle' + dies 'day', ), while others describe south as the right-hand side of the rising sun, like Biblical Hebrew תֵּימָן teiman 'south' from יָמִין yamin 'right', Aramaic תַּימנַא taymna from יָמִין yamin 'right' and Syriac ܬܰܝܡܢܳܐ taymna from ܝܰܡܝܺܢܳܐ yamina (hence the name of Yemen, the land to the south/right of the Levant). South is sometimes abbreviated as S. Navigation By convention, the ''bottom or down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Arthropod
Arthropods ( ) are invertebrates in the phylum Arthropoda. They possess an arthropod exoskeleton, exoskeleton with a cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate, a body with differentiated (Metamerism (biology), metameric) Segmentation (biology), segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They form an extremely diverse group of up to ten million species. Haemolymph is the analogue of blood for most arthropods. An arthropod has an open circulatory system, with a body cavity called a haemocoel through which haemolymph circulates to the interior Organ (anatomy), organs. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. They have ladder-like nervous systems, with paired Anatomical terms of location#Dorsal and ventral, ventral Ventral nerve cord, nerve cord ...
