Document Summary
When the environment becomes colder the fur compensates for the change (phenotypic) Changes in morphology or behavior that either helps them coexist or one is eliminated. Species go to great lengths in order to coexist because otherwise the price is very high for one or both species. When two or more species need the same resource (-/-) The two minus signs signify the negative effect the two species would have on one another. The resources used by one reduces for the other, diminishing the supply. This should raise the idea of niche and niche packing. The addition sign would be the predator and the minus sign for the prey. Conflict of outcome in this scenario for the prey. Critical to at least one of the symbionts. Sometimes difficult to see in other species and difficult to measure. The concept of ghost of competition past is evidence that competition happened previously.
