Welcome to JAAN's science class!!

Big hi to all of you! I'm an undergraduate following a Bsc in bioscience. Trust me I know the feeling of surfing around the net for ages and getting nothing in return! Or getting something worthless for the time we spent surfing. So I started this blog adding the science stuff I have noted which I think might help someone in their home work. Ok then enjoy!

Population dispersion

Dispersion is the pattern of spacing among the individuals within the population. Basically there are three patterns.
-          Clumped dispersion
-          Uniform(regular) dispersion
-          Random dispersion


Clumped
·         Commonest pattern that can observed in populations.
·         Individuals are bunched into groups within the population.
·         This is mainly results from the response to the unevenly distributed resources in their environment.
·         Also there are positive interactions between the individuals.
·         This supplies many advantages to the population such as protection from predators, reproduce and increase the population size and decrease the energetic cost of moving to do work.


Uniform
·         Individuals are uniformly spaced within the population.
·         Mainly results from the competition for resources.
·         Therefore there are aggressive interactions between the neighbours.


Random
·         Individuals are randomly spaced within the community.
·         Not that much common in nature.
·         This occurs as there are no strong interactions between the individuals.
·         They show neutral interactions.
