Tropical Forests
To understand where and why tropical forests exist, one must begin with some essential facts of geography and climatic systems. By definition, ‘the tropics’ lie between 238N and 238S latitude, the area within which the sun lies directly overhead at some point in its seasonal progression. Thefluxof solar energywithin this region is high, due to the fact that incoming sunlight is projected at a 9...
متن کاملFloristic diversity assessment and vegetation analysis of tropical semievergreen forest of Manipur, north east India
The present paper aimed to study the floristic diversity of Dipterocarpus tuberculatus dominated forest of Manipur situated along the Indo-Myanmar Border, north-eastern India. A total of 123 species belonging to 48 families were recorded. The quantitative features such as density and importance value index of species varied greatly. In the present study the diversity index of shrubs and herbs w...
متن کاملDispersal, environment, and floristic variation of western Amazonian forests.
The distribution of plant species, the species compositions of different sites, and the factors that affect them in tropical rain forests are not well understood. The main hypotheses are that species composition is either (i) uniform over large areas, (ii) random but spatially autocorrelated because of dispersal limitation, or (iii) patchy and environmentally determined. Here we test these hypo...
متن کاملGeological control of floristic composition in Amazonian forests
AIM: Conservation and land-use planning require accurate maps of patterns in species composition and an understanding of the factors that control them. Substantial doubt exists, however, about the existence and determinants of large-area floristic divisions in Amazonia. Here we ask whether Amazonian forests are partitioned into broad-scale floristic units on the basis of geological formations a...
متن کاملFloristic Classification of Large-Scale Ecological Groups in the Forests of Central Zagros
Do climatic variations and drought magnitude affect large-scale vegetation composition in the Central Zagrosian forests, and to what extent do topographic variables of altitude and aspect play a role in these potential differences? To answer this question, in this research, the flora list of 15 Central Zagros forests was obtained in five plant life forms between the valleys of two rivers, Gerdb...
