Biodiversity is not uniformly distributed across the geographical regions of the earth. Certain regions of the world are flourished with a very large number of different species. Hot spots are the richest and most threatened reservoirs of plant and animal life on earth. There are about 34 hot spots identified in the world. Among this‚ India has two hot spots namely Western Ghats and Eastern Himalayas. The Western Ghats hot spot region lies parallel to the eastern coast of Indian peninsula

HARDWOOD Hardwood is wood from angiosperm trees (more strictly speaking non-monocot angiosperm trees). It may also be used for those trees themselves: these are usually broad-leaved; in temperate and boreal latitudes they are mostly deciduous‚ but in tropics and subtropics mostly evergreen. Hardwood contrasts with softwood (which is from Gymnosperm trees). Hardwoods are not necessarily harder than softwoods. In both groups there is an enormous variation in actual wood hardness‚ with the range in

of leaves. • Softwoods grow faster than hardwood so are cheaper. • Often used as building material. • Trees grow tall and straight which makes it easier for the manufacturer to cut long straight planks of wood. Hardwoods Hardwoods come from deciduous or broad-leafed trees. They are generally slow growing which tends to make them harder and more expensive. Please note though that not all hardwoods are hard‚ Balsa which is very soft and is often used for model planes is in fact a balsa wood! Hardwoods

Notice that the Gross Primary Productivity (P) of the alfalfa field and the deciduous forest are not too different from each other. However‚ the Plant Respiration (RP) in the forest is almost double that in the alfalfa field. What factors (physical‚ chemical‚ or biological) do you think might explain this difference? The difference would have to be the biological and physical factors. The reason for this is the cycle in deciduous forest goes through. Tree insects and diseases are most common in older

What Is a Forest Ecosystem? Forests are important ecosystems that provide environmental and economic benefits. Forest ecosystems are unique environments and are categorized based on the types and ages of trees‚ climate and soil. They impact the environment at scales ranging from local to regional‚ by influencing climate‚ nutrient dynamics and water movement. Forests are found all over the world‚ and they provide valuable economic and environmental services. Information About a Forest Ecosystem

moderating the effects of sun‚ wind‚ and rain. Radiant energy from the sun is absorbed or deflected by leaves on deciduous trees in the summer and is only filtered by branches of deciduous trees in winter. We are cooler when we stand in the shade of trees and are not exposed to direct sunlight. In winter‚ we value the sun’s radiant energy. Therefore‚ we should plant only small or deciduous trees on the south side of homes. Wind speed and direction can be affected by trees. The more compact the foliage
