Chestnut-throated Huet-huet
The chestnut-throated huet-huet (''Pteroptochos castaneus'') is a large passerine bird of the family Rhinocryptidae. At an average mass of , it is, with the related black-throated huet-huet, the largest rhinocryptid and the third-heaviest tracheophone suboscine behind the giant and great antpittas.del hoyo, Joseph; Elliott, Andrew and Christie, David; ''Handbook of the Birds of the World: Volume 8 – Broadbills to Tapaculos''; p. 765. It is a stockily-built bird, averaging in length with a predominantly dark brown plumage except for a dark red throat and a pale buff bar on its wind – lacking in the black-throated species. For many decades intense debate existed as to whether these two were one species or two,Johnson, Alfredo William; ''The Birds of Chile and Adjacent Regions of Argentina, Peru and Bolivia'' (volume II), pp. 201-210. but molecular studies in the 1990s demonstrated that the two species had been separated since before the Patagonian Ice Sheet first formed in so ...

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich Pestalozzi (1746–1827). The teaching included the use o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maule Region
The Maule Region ( es, Región del Maule, ) is one of Chile's 16 first order administrative divisions. Its capital is Talca. The region derives its name from the Maule River which, running westward from the Andes, bisects the region and spans a basin of about 20,600 km2. The Maule river is of considerable historic interest because, among other reasons, it marked the southern limits of the Inca Empire. Geography and ecology The region covers an area of and is bordered on the west by the Pacific Ocean; on the east by the Argentina; on the north by the O'Higgins Region, and on the south by the Ñuble Region. There are a number of flora and fauna species present in Maule. For example, the endangered Chilean Wine Palm (''Jubaea chilensis'') is found in a very limited distribution that includes the Maule Region. The limited distribution ''Nothofagus alessandri'' is also found in the region. Demography According to the 2017 census, the population of the region was 1,033,197. Wi ...

Bird Nest
A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. Although the term popularly refers to a specific structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests is known as ''caliology''. Not all bird species bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maulino Forest
Maulino forest ( es, Bosque Maulino) is a forest type naturally growing in the Chilean Coast Range of Central Chile from latitude 35°55 to 36°20 S. The chief tree species is ''Nothofagus glauca''. Other tree species include '' Nothofagus leonii'', ''Nothofagus alessandri'' and ''Gomortega keule''. The forest grows at a transition zone between Mediterranean climate to humid temperate climate. Precipitations vary from 1000 to 700 mm/a and are concentrated in winter. According to geographers Humberto Fuenzalida and Edmundo Pisano the forest is one of mesophytes on the transition zone of temperate rain forests. José San Martín and Claudio Donoso identify three forest subtypes: *''Nothofagus glauca'' forests *''Nothofagus antarctica'' forests *''Nothofagus alessandri'' forest Maulino forest stand out for its high degree of endemism. Fragmentation and degradation Large swathes of former Maulino forest were cleared for agriculture. This led to significant soil erosion before the area ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habitat ...

Understory
In forestry and ecology, understory (American English), or understorey (Commonwealth English), also known as underbrush or undergrowth, includes plant life growing beneath the forest canopy without penetrating it to any great extent, but above the forest floor. Only a small percentage of light penetrates the canopy so understory vegetation is generally shade-tolerant. The understory typically consists of trees stunted through lack of light, other small trees with low light requirements, saplings, shrubs, vines and undergrowth. Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential emergent trees into competitive growth as they grow upwards to fill the gap. These trees tend to have straight trunks ...

Pinus Radiata
''Pinus radiata'' ( syn. ''Pinus insignis''), the Monterey pine, insignis pine or radiata pine, is a species of pine native to the Central Coast of California and Mexico (Guadalupe Island and Cedros island). It is an evergreen conifer in the family Pinaceae. ''P. radiata'' is a versatile, fast-growing, medium-density softwood, suitable for a wide range of uses. Its silviculture reflects a century of research, observation and practice. It is often considered a model for growers of other plantation species. It is the most widely planted pine in the world, valued for rapid growth and desirable lumber and pulp qualities. Although ''P. radiata'' is extensively cultivated as a plantation timber in many temperate parts of the world, it faces serious threats in its natural range, due to the introduction of pine pitch canker (''Fusarium circinatum''). Description ''P. radiata'' is a coniferous evergreen tree growing to tall in the wild, but up to in cultivation in optimum conditi ...

Neuquén Province
Neuquén () is a province of Argentina, located in the west of the country, at the northern end of Patagonia. It borders Mendoza Province to the north, Rio Negro Province to the southeast, and Chile to the west. It also meets La Pampa Province at its northeast corner. History The Neuquén Province receives its name from the Neuquén River. The term ''"Neuquén"'' derives from the Mapudungun word ''"Nehuenken"'' meaning ''drafty'', which the aborigines used for the river. The word (without the accentuation) is a palindrome. Lácar Department in Neuquén Province has the southernmost known remains of maize before it was further diffused by the Inca Empire. Maize remains were found as far south as 40°19' S in Melinquina, with it being found inside pottery dated to 730 ±80 BP and 920 ±60 BP. This maize was probably brought across the Andes from Chile. Inhabited by Tehuelches and Pehuenche, the territory was initially explored by conquistadores coming from Chile. In 1670 a Jesu ...
