A community is an assemblage of species living close enough together for potential interaction which differ in their species richness, species evenness, and relative abundance of different species. In an ecosystem, there are various species-specific niches either isolated or overlapped.…
Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water, or nutrients from the soil. Because plants cannot walk around and take their…
Land productivity is a measure of the amount of sustainable land use, determined as the relationship between land quality in overall productive terms and output. It can show a land’s potential to support and maintain life and can be used…
In the natural world, no organism exists in absolute isolation. The first law of ecology states, ” everything is connected with everything”. There is a continuous interaction between and among the biotic organisms and their interaction with abiotic interaction. This…
Habitat loss, Habitat fragmentation, and Habitat destruction are often analogous to each other. They are interconnected being cause or effect of similar reasons. In order to understand habitat fragmentation first, we need to understand about Habitat destruction. Habitat destruction is…
Stochasticity is something that is randomly determined or happens by chance. Random variation or stochasticity in the environment influences Growth, Food availability, prey-predator relation, Population size, colonization, and random order of immigration/ emigration which ultimately determines the population dynamics of…
The concept of Metapopulation is coined by Richard Levins in 1969. Meta-population consists of a group of spatially separated populations of the same species which are linked by migration, dispersal, and extinction. Thus even if all members of one population…
Conversion in forestry is defined as a change from one silvicultural system or one (set of) species to another. Importance of Conversion A.Change in Crop Composition Increase yield from the forest Plantation of fast-growing species like eucalyptus, species have less…
It is a silvicultural system in which equal or equi-productive areas of mature crops are successively clear-felled in one operation to be regenerated most frequently, artificially but sometimes naturally also. The entire crop of the coupe should be felled and…
GIS is an integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image and other resource data is geographically referenced. NASA The major functions of GIS comprise: Mapping Managing spatially referenced data Design and planning…
