Blackish Tapaculo
The blackish tapaculo (''Scytalopus latrans'') is a species of bird in the family Rhinocryptidae. It is found in Colombia, Ecuador, Peru, and Venezuela. Taxonomy and systematics The blackish tapaculo was originally described by Hellmayr as a species. Later it was reclassified as a subspecies of unicolored tapaculo (''Scytalopus unicolor'') and later still returned to full species status.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S.

Carl Eduard Hellmayr
Carl Eduard Hellmayr (29 January 1878 in Vienna, Austria – 24 February 1944 in Orselina, Switzerland) was an Austrian ornithologist. Biography Hellmayr was born in Vienna and studied at the University of Vienna, although he did not complete his degree. After his studies he worked in Vienna, Munich, Berlin, Paris, Tring (England), and Chicago. He spent the years 1905–1908 studying Baron Rothschild's private collection of natural history specimens at Tring, near London. There he received guidance from the German ornithologist Ernst Hartert. In 1908, Hellmayr was appointed Curator of the Bird Department at the Bavarian State Museum, which he had helped organize in 1903 and where he became a specialist in Neotropical birds, studying Johann Baptist von Spix's collection of Brazilian birds. In 1922, he was made Curator in Zoology at the Field Museum in Chicago. He stayed there until 1931. His books included 13 of the 15 volumes of the ''Catalogue of Birds of the Americas'' (19 ...

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 arbor ...

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, ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 adapted for flight. Some bird species of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scytalopus
''Scytalopus'' is a genus of small passerine birds belonging to the tapaculo group. They are found in South and Central America from Tierra del Fuego to Costa Rica, but are absent from the Amazon Basin. They inhabit dense vegetation at or near ground-level and are mainly found in mountainous regions, particularly the Andes. They can be very difficult to see as they run through the undergrowth in a mouse-like fashion. Description They are plump with short tails that often are held cocked. Depending on species, the total length is 10–14 cm (4-5½ in). Their plumage is blackish or grey. Several species have brown bellies, rumps or flanks; often with some barring. A few have white crowns or eyebrows. Juveniles of most species are browner and have barred flanks. Many species are essentially impossible to separate by their plumage, but songs and calls are often distinctive and important for species identification. Behavior Their diet consists mainly of insects. Little is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and 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 building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Selaginella
''Selaginella'' is the sole genus of vascular plants in the family Selaginellaceae, the spikemosses or lesser clubmosses. This family is distinguished from Lycopodiaceae (the clubmosses) by having scale-leaves bearing a ligule and by having spores of two types. They are sometimes included in an informal paraphyletic group called the "fern allies". '' S. moellendorffii'' is an important model organism. Its genome has been sequenced by the United States Department of Energy's Joint Genome Institute. The name ''Selaginella'' was erected by Palisot de Beauvois solely for the species ''Selaginella selaginoides'', which turns out (with the closely related ''Selaginella deflexa'') to be a clade that is sister to all other ''Selaginellas'', so any definitive subdivision of the species into separate genera leaves two taxa in ''Selaginella'', with the hundreds of other species in new or resurrected genera. ''Selaginella'' occurs mostly in the tropical regions of the world, with a hand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phenology
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonality, seasonal and interannual variations in climate, as well as environmental factor, habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of bird migration, migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy (climate), proxy for ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. 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. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chusquea
''Chusquea'' is a genus of evergreen bamboos in the grass family. Most of them are native to mountain habitats in Latin America, from Mexico to southern Chile and Argentina. They are sometimes referred to as South American mountain bamboos. Unlike most other grasses, the stems of these species are solid, not hollow. Some animals are, to various extents, associated with stands of ''Chusquea'', for example the Inca wren, monito del monte, and the plushcap. Notable species ''Chusquea culeou'', the chilean feather bamboo or colihue cane, from southern Chile and adjacent western Argentina, is notable as the most frost-tolerant South American bamboo and the only one that has been grown successfully to any extent in the temperate Northern Hemisphere, with successful growth as an ornamental plant north to Scotland. The colihue cane was used by the Mapuches Indians to make instruments and as lances during the War of Arauco. ''Chusquea quila'' (in Spanish ''quila''), in contrast to Coli ...
