Guttulate Foliage-gleaner
The guttulate foliage-gleaner (''Syndactyla guttulata'') is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Venezuela. Taxonomy and systematics The guttulate foliage-gleaner was originally described as ''Anabazenops guttulatus''. It early acquired the English name "guttulated foliage-gleaner", a name which persisted until it was pointed out that the word ''guttulated'' does not exist in English. "Webster's International indeed states that the English noun ''guttula'' is an obscure word for a drop-shaped spot, and the adjectival form is ''guttulate'', not "guttulated". The guttulate foliage-gleaner has two subspecies, the nominate ''S. g. guttulata'' ( Sclater, PL, 1858) and ''S. g. pallida'' ( Zimmer, JT & Phelps, WH, 1944). Description The guttulate foliage-gleaner is long and weighs . It is a largish furnariid with a more wedge-shaped bill than many others of its genus. The sexes have the same plumage. Adults of ...

Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River, canoeing down it to the Mississippi. Sclater w ...

Aragua
Aragua State ( es, Estado Aragua, ) is one of the 23 states of Venezuela. It is located in the north-central region of Venezuela. It has plains and jungles and Caribbean beaches. The most popular are Cata and Choroni. It has Venezuela's first national park which is called Henri Pittier. The capital is Maracay, other important cities include Turmero and El Limón. Aragua State covers a total surface area of and, based on the 2011 census information, the estimated population of Aragua State in 2012 is 1,630,308 inhabitants. Etymology The name of the state comes from an indigenous word of Cumanagoto (Caribbean) origin, which is used to refer to the Chaguaramo, a type of palm from the region uotation requiredHowever, according to Carlos Blanco Galeno, a chronicler from Turmero, it derives from the Cariban aregua, and this de are ('site') and gua which in turn derives from ogun ('my thing'), so it would mean 'my place, my country'.

Syndactyla
''Syndactyla'' is a genus of foliage-gleaners, birds in the ovenbird family Furnariidae. Taxonomy The genus ''Syndactyla'' was introduced in 1853 by the German naturalist Ludwig Reichenbach to accommodate the buff-browed foliage-gleaner. The name combines the Ancient Greek ''sun'' meaning "together" with ''daktulos'' meaning "toe". Members of this genus are most closely related to the foliage-gleaners in the genus ''Anabacerthia''. A high resolution version of the phylogenetic tree in Figure 1 is available from the first author's websithere The recurvebills, ''S. ucayalae'' and ''S. striata,'' were formerly placed in their own genus ''Simoxenops,'' ''and S. roraimae'' was formerly placed in the genus ''Automolus''. Species The genus contains eight species: * Lineated foliage-gleaner, ''Syndactyla subalaris'' * Guttulate foliage-gleaner, ''Syndactyla guttulata'' * Buff-browed foliage-gleaner, ''Syndactyla rufosuperciliata'' * Rufous-necked foliage-gleaner, ''Syndactyl ...

Henri Pittier National Park
Henri Pittier National Park is the oldest national park in Venezuela, originally created in 1937 under the name of ''Rancho Grande'' by decree of President Eleazar López Contreras. In 1953 the park was renamed in honor of Henri Pittier, a distinguished Swiss geographer, botanist and ethnologist, who arrived in Venezuela in 1917, classified more than 30,000 plants in the country and devoted many years studying the flora and fauna in the park. Henry Pittier National Park has the honor of having started the history of national parks of Venezuela. Its 107,800 hectares, located in the north of Aragua state, comprise most of the Araguan coast and mountainous area of Carabobo state. It also borders San Esteban National Park. Henri Pittier National Park is the largest among the national parks of the Venezuelan Coastal Range. The park consists of two geographic systems: a steep mountainous interior where there are more than 500 bird species and 22 endemic species and a coastal area with ...

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] |
Bromeliad
The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, '' Pitcairnia feliciana''. It is among the basal families within the Poales and is the only family within the order that has septal nectaries and inferior ovaries.Judd, Walter S. Plant systematics a phylogenetic approach. 3rd ed. Sunderland, MA: Sinauer Associates, Inc., 2007. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both epiphytes, such as Spanish moss ('' Tillandsia usneoides''), and terrestrial species, such as the pineapple ('' Ananas comosus''). Many bromeliads are able to store water in a structure formed by their tightly overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte '' Tillandsia'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Army Ant
The name army ant (or legionary ant or ''marabunta'') is applied to over 200 ant species in different lineages. Because of their aggressive predatory foraging groups, known as "raids", a huge number of ants forage simultaneously over a limited area. Another shared feature is that, unlike most ant species, army ants do not construct permanent nests; an army ant colony moves almost incessantly over the time it exists. All species are members of the true ant family, Formicidae, but several groups have independently evolved the same basic behavioural and ecological syndrome. This syndrome is often referred to as "legionary behaviour", and may be an example of convergent evolution. Most New World army ants belong to the genera '' Cheliomyrmex'', '' Neivamyrmex'', ''Nomamyrmex'', ''Labidus'', and '' Eciton''. The largest genus is ''Neivamyrmex'', which contains more than 120 species; the most predominant species is '' Eciton burchellii''; its common name "army ant" is considered ...

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.

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] |
Secondary Forest
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.

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 Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of , Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and O ...

Primary Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree hei ...
