Iwokrama Forest
The Iwokrama Forest is a nature reserve of central Guyana located in the heart of the Guiana Shield, one of the four last pristine tropical forests in the world (Congo Basin, Congo, New Guinea, and the Amazon rainforest are the others). It represents an important transition zone in rainfall, landforms, human histories and biological communities. At its widest, the area is , and the greatest extent in a north–south direction is 80 km (50 mi). The Georgetown–Lethem Road dissects the forest, traversing about between the northeastern and southern boundaries. The forest lies between 4th parallel north, 4° and 5th parallel north, 5° north latitude and 58.5 and 59.5 degrees west longitude. The Iwokrama Forest is bordered to the west by the Pakaraima Mountains and to the east by the isolated highlands scattered through central-east Guyana. It is also bordered by savannahs in the southwest and northeast of Guyana. The Essequibo River forms the eastern boundary. The northe ...

Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Natural History Of Guyana
Nature is an inherent character or constitution, particularly of the Ecosphere (planetary), ecosphere or the universe as a whole. In this general sense nature refers to the Scientific law, laws, elements and phenomenon, phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright Anthropocentrism, separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Jean-Jacques Rousseau, Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iwokrama International Centre For Rain Forest Conservation And Development
The Iwokrama International Centre for Rain Forest Conservation and Development is an autonomous non-profit institution established by Guyana and the Commonwealth. It "exists to promote the conservation and the sustainable and equitable use of tropical rain forests in a manner that leads to lasting ecological, economic, and social benefits to the people of Guyana and to the world in general, by undertaking research, training, and the development and dissemination of technologies". It started in 1989 as a gift to the Commonwealth by late president Desmond Hoyte, and the Iwokrama Act signed by late President Cheddi Jagan in 1996 officially established the center. The Iwokrama Programme received its first sizeable financial input in 1993 when the "United Nations Development Programme - UNDP" office in Guyana implemented the first Iwokrama project and secured a "Global Environment Facility - GEF" grant of US$3Million as seed money for establishing the programme. The UNDP/GEF project do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macushi
The Macushi (''Makuusi'', ) are an Indigenous people living in the borderlands of southern Guyana, northern Brazil in the state of Roraima, and in an eastern part of Venezuela. Identification The Macushi are also known as the Macusi, Macussi, Makushi, Makusi, Makuxi, Teueia, and Teweya people. Macushi, as well as the Arecuna, Kamarakoto, and Taurepan are considered sub-groups of Pemon.

Chrysobalanaceae
Chrysobalanaceae is a family of flowering plants, consisting of trees and shrubs in 27 genera and about 700 species of pantropical distribution with a centre of diversity in the Amazon. Some of the species contain silica in their bodies for rigidity and so the mesophyll often has sclerenchymatous idioblasts. The widespread species '' Chrysobalanus icaco'' produces a plum-like fruit and the plant is commonly known as the coco plum. The family was traditionally placed as subfamily Chrysobalanoideae in the rose family (Rosaceae) or as a family in the rose order and exceptionally as an order in Myrtiflorae by Dahlgren In the phenotypic cladistic analysis of Nandi et al., it branched with Elaeagnaceae as sister group of Polygalaceae, in their molecular cladistic analysis it was in Malpighiales and also in their combined analysis.Nandi, O.L., Chase, M.W., & Endress, P.K. 1998.

Bird
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. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Giant Anteater
The giant anteater (''Myrmecophaga tridactyla'') is an Insectivore, insectivorous mammal native to Central America, Central and South America. It is the largest of the four living species of anteaters, which are classified with sloths in the order (biology), order Pilosa. The only extant member of the genus ''Myrmecophaga'', the giant anteater is mostly terrestrial, in contrast to other living anteaters and sloths, which are arboreal or semiarboreal. The species is in length, with weights of for males and for females. It is recognizable by its elongated snout, bushy tail, long foreclaws, and distinctively colored fur. The giant anteater is found in multiple habitats, including grassland and rainforest. It forages in open areas and rests in more forested habitats. It feeds primarily on ants and termites, using its foreclaws to dig them up and its long, sticky tongue to collect them. Though giant anteaters live in overlapping home ranges, they are mostly solitary except during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
