Pueblo State Forest
Bosque del Pueblo (''People's Forest'') is one of the 20 forest units that make up the public forest system of Puerto Rico. The 738-acres forest is located in the municipality of Adjuntas and it comprises a preserved zone which was endangered of being developed as a quarry between the years 1980 and 1995. The forest is located in lands shared by the Adjuntas barrios or districts of Vegas Arriba, Vegas Abajo and Pellejas de Adjuntas. In addition to preserving the forest, the reserve is important to the preservation of the hydrological basins of the Pellejas and Viví Rivers, and many of the tributaries of the Arecibo River have their sources in the forest lands. The forest also functions as an ecological corridor between the Guilarte, Río Abajo and Toro Negro Forests. History The area where the forest was established is rich in gold, silver and copper deposits and was intended to be developed as an open-air mine. Between the years 1980 and 1995 the cultural and environme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-whiskered Vireo (Vireo Altiloquus) (6499240363)
The black-whiskered vireo (''Vireo altiloquus'') is a small passerine bird, which breeds in southern Florida, USA, and the West Indies as far south as the offshore islands of Venezuela. It is a partial migrant, with northern birds wintering from the Greater Antilles to northern South America. This species has occurred as a rare vagrant to Costa Rica. Habitat The breeding habitat is open deciduous wooded areas and cultivation, and in Florida also mangroves. The black-whiskered vireo builds a cup nest in a fork of a tree branch, and lays 2-3 white eggs. Description This vireo is 14–15 cm in length, has a 25 cm wingspan and weighs 17–19 g. It has thick blue-grey legs and a stout bill. The adult black-whiskered vireo has dull olive-green upperparts and white underparts, with yellowish on the flanks and under the tail. It has red eyes and a grey-brown crown with faint dusky edges. There is a dark line through the eyes and a white eyebrow stripe. There is a distinctiv ...

Copper Extraction
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
