Jean Cabanis
Jean Louis Cabanis (8 March 1816 – 20 February 1906) was a German ornithologist. He worked at the bird collections of the Natural History Museum in Berlin becoming its first curator of birds in 1850. He founded the ''Journal für Ornithologie'' in 1853''.'' Biography Cabanis was born in Berlin to an old Huguenot family who had moved from France. His father Benoit-Jean (1774–1838) and mother Maria Luise (1783–1849) both came from families that were in the textile industry. Little is known of his early life. He studied at the University of Berlin from 1835 to 1839, and then travelled to North America, working as a museum assistant in Carolina. He returned in 1841 with a large natural history collection. He was assistant at the Natural History Museum, Berlin, Natural History Museum of Berlin (which was at the time the Berlin University Museum) and in 1850 he became the curator of birds, taking over from Martin Lichtenstein. Charles Lucien Bonaparte had offered him a positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mixed-species Feeding Flock
A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. These are different from feeding aggregations, which are congregations of several species of bird at areas of high food availability. While it is currently unknown how mixed-species foraging flocks originate, researchers have proposed a few mechanisms for their initiation. Many believe that nuclear species play a vital role in mixed-species flock initiation. Additionally, the forest structure is hypothesized to play a vital role in these flocks' formation. In Sri Lanka, for example, vocal mimicry by the greater racket-tailed drongo might have a key role in the initiation of mixed-species foraging flocks, while in parts of the American tropics packs of foraging golden-crowned warblers might play the same role. Composition Mixed-species foragin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guadua
''Guadua'' is a Neotropical genus of thorny, clumping bamboo in the grass family, ranging from moderate to very large species. Physically, '' Guadua angustifolia'' is noted for being the largest Neotropical bamboo. The genus is similar to ''Bambusa'' and is sometimes included in that genus. Several animals are, to a various extent, associated with stands of ''Guadua'' bamboo, for example several species of seedeaters, and the Amazon and Atlantic Bamboo Rats. Distribution and habitats The genus can be found in a wide range from northern Mexico and Trinidad to Uruguay, but most of the species are concentrated in the Amazon basin and the Orinoco basin. They usually grow at low altitudes (below 1,500 m), but has been found up to 2,500 m. Its habitats include lowland tropical and lower-montane forest, savannas, Cerrados, gallery forest, and disturbed inter-Andean valley vegetation. Human use From a utilitarian perspective, ''Guadua'' is the most important American bamboo. Due to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Araucaria
''Araucaria'' (; original pronunciation: [a.ɾawˈka. ɾja]) is a genus of evergreen coniferous trees in the family Araucariaceae. While today they are largely confined to the Southern Hemisphere, during the Jurassic and Cretaceous they were globally distributed. There are 20 extant taxon, extant species in New Caledonia (where 14 species are endemism, endemic, see New Caledonian Araucaria, New Caledonian ''Araucaria''), eastern Australia (including Norfolk Island), New Guinea, Argentina, Brazil, Chile and Uruguay. The genus is familiar to many people as the genus of the distinctive Chilean pine or monkey-puzzle tree (''Araucaria araucana''). No distinct vernacular name exists for the genus. Many are called "pine", although they are only distantly related to true pines, in the genus ''Pinus''. Description ''Araucaria'' are mainly large trees with a massive erect stem, reaching a height of . The horizontal, spreading branches grow in whorls and are covered with leather ...

Cerrado
The Cerrado () is a vast ecoregion of Tropics, tropical savanna in central Brazil, being present in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins, Maranhão, Piauí, Bahia, Minas Gerais, São Paulo (state), São Paulo, Paraná (state), Paraná and the Federal District (Brazil), Federal District. The core areas of the Cerrado biome are the Brazilian highlands – the ''Planalto''. The main habitat types of the Cerrado consist of forest savanna, wooded savanna, park savanna and grass, gramineous-woody savanna. The Cerrado also includes savanna wetlands and gallery forests. The second largest of Biomes in Brazil, Brazil's major habitat types, after the Amazon rainforest, Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia). About 75% of the Cerrado’s 2 million km2 is privately owned. Vast amounts of research have shown that the Cerrado is one of the richest of all tropi ...

Ecotone
An ecotone is a transitional area between two plant communities, where these meet and integrate. Examples include areas between grassland and forest, estuaries and lagoon, freshwater and sea water etc. An ecotone may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems). An ecotone may appear on the ground as a gradual blending of the two communities across a broad area, or it may manifest itself as a sharp boundary line. Etymology The word ''ecotone'' was coined (and its etymology given) in 1904 in "The Development and Structure of Vegetation" (Lincoln, Nebraska: Botanical Seminar) by Frederic E. Clements. It is formed as a combination of ''ecology'' plus ''-tone'', from the Greek ''tonos'' or tension – in other words, a place where ecologies are in tension. Features There are several distinguishing features of an ecotone. First, an ecotone can have a sharp vegetation transition, wi ...

Secondary Forest
A secondary forest (or second-growth forest) is a forest or woodland area which has regenerated through largely natural processes after human-caused Disturbance (ecology), disturbances, such as Logging, timber harvest or agriculture clearing, or equivalently disruptive natural phenomena. It is distinguished from an old-growth forest (primary or primeval forest), which has not recently undergone such disruption, and complex early Seral community, 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 Ecological succession, regrowing after natural Disturbance (ecology), disturbances such as Wildfire, fire, insect infestation, or windthrow because the dead trees remain to provide nutrients, structure, and water retention after natural disturbances. Secondary forests are notably different from primary forests in their composition and biodiversity; however, they may still be hel ...

Evergreen Forest
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones. Species of trees Coniferous temperate evergreen forests are most frequently dominated by species in the families. The trees include: Pinaceae and Cupressaceae. Broadleaf temperate evergreen forests include those in which Fagaceae, such as oaks and ferns are common, those in which Nothofagaceae predominate, and the eucalyptus forests of the Southern Hemisphere. There also are assorted temperate evergreen forests dominated by other families of trees, such as Lauraceae in laurel forest. Regions Coniferous temperate evergreen forests are found largely in the temperate mid-latitudes of Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco basins of South America, ...
