Intraspecific competition

As is evident from the first few posts of this blog, there's been a distinctly biological theme. Whereas biology is the science of life and living organisms ~ to include their morphology, function, evolution and distribution, ecology, or bionomics, is the science relating to the relationship those organisms have with each other and their habitat or environment.
The arachnid, a predatory figure and the web, the capture device ~ the behaviour of one organism and the resulting impact on another are symbolic and the series of episodes that occurred within my marriage and some that occurred after my divorce that will be revealed later on certainly bear much similarity.

An organism's survival is dependent upon the availability of resources within the environment. When resources are limited, competition ensues ~ competition being an interaction that is mutually detrimental to species that share the same resources and one that occurs when a resource is in short supply relative to the numbers seeking it. More specifically it is an interaction in which two or more individuals or species utilise the same limited resources. This can be further broken down to interspecific and intraspecific competition. Intraspecific competition occurs when members of one species interact to the detriment of each and for the same limited resources.
Competition for resources, the driving force of evolution and natural selection, results in the dominance of the variation of the species best suited for survival. Although Darwin posed that intraspecific competition results in organisms better suited for survival that would, over time, adapt and evolve to the environment in which they lived, let's hope in this instance that history will prove Darwin wrong.
