Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned speci ...

Polylepis
''Polylepis'' is a genus comprising 28 recognised shrub and tree species, that are endemic to the mid- and high-elevation regions of the tropical Andes. This group is unique in the rose family in that it is predominantly wind-pollinated. They are usually gnarled in shape, but in certain areas some trees are 15–20 m tall and have 2 m-thick trunks. The foliage is evergreen, with dense small leaves, and often having large amounts of dead twigs hanging down from the underside of the canopy. The name ''Polylepis'' is, in fact, derived from the Greek words poly (many) plus letis (layers), referring to the shredding, multi-layered bark that is common to all species of the genus. The bark is thick and rough and densely layered for protection against low temperatures. Some species of ''Polylepis'' form woodlands growing well above normal tree line within grass and scrub associations at elevations over 5000 m; which makes ''Polylepis'' appear to be the highest naturally occurring arbora ...

Secondary Woodland
A secondary forest (or second-growth forest) is a forest or woodland area which has re-grown after a timber harvest or clearing for agriculture, until a long enough period has passed so that the effects of the disturbance are no longer evident. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early seral forest, as well as third-growth forests that result from harvest in second growth forests. Secondary forest regrowing after timber harvest differs from forest regrowing after natural disturbances such as fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. However, often after natural disturbance the timber is harvested and removed from the system, in which case the system more closely resembles secondary forest rather than seral forest.

American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, ''The Auk'' and '' The Condor'' as well as the ''AOS Checklist of North American Birds''. In 2013, the American Ornithologists' Union announced a close partnership with the Cooper Ornithological Society, including joint meetings, a centralized publishing office, and a refocusing of their respective journals to increase efficiency of research. In October 2016, the AOU announced that it was ceasing to operate as an independent union and was merging with the Cooper Ornithological Society to create the American Ornithological Society.

Huallaga River
The Huallaga River is a tributary of the Marañón River, part of the Amazon Basin. Old names for this river include ''Guallaga'' and ''Rio de los Motilones''. The Huallaga is born on the slopes of the Andes in central Peru and joins the Marañón before the latter reaches the Ucayali River to form the Amazon. Its main affluents are the Monzón, Mayo, Biabo, Abiseo and Tocache rivers. Coca is grown in most of those valleys, which are also exposed to periodic floods. Description Although it runs for 700 miles (1,100 km), it remains unnavigable for the most part. For nearly its entire length the Huallaga is an impetuous torrent running through a succession of gorges. It has forty-two rapids (pongos) and it crosses the Andes, forming the Pongo de Aguirre gorge. From this point, from the Amazon, the Huallaga can be ascended by larger river boats (''lanchas'') to the port city of Yurimaguas, Loreto. Although there are no defined boundaries, the river is commonly divided into tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Department Of Piura
Piura () is a coastal department and region in northwestern Peru. The region's capital is Piura and its largest port cities, Paita and Talara, are also among the most important in Peru. The area is known for its tropical and dry beaches. It is the most populous department in Peru, its twelfth smallest department, and its fourth-most densely populated department, after Tumbes, La Libertad, and Lambayeque. The country's latest decentralization program is in hiatus after the proposal to merge departments was defeated in the national referendum in October 2005. The referendum held on October 30, 2005, as part of the ongoing decentralization process in Peru, to decide whether the region would merge with the current regions of Lambayeque and Tumbes to create a new ''Región Norte'' was defeated. Geography The Piura Region is bordered to the north by the Tumbes Region and Ecuador, to the east by Cajamarca Region, to the south by the Lambayeque Region, and to the west by the Pac ...
