5.I measure the use of nuts, trees and nesting
materials by two species of squirrel and find some strong overlaps in the uses
of nesting materials in particular. Is
it safe to conclude that these two species are competitors? Why or why not?
yes. Competition is only one of many interacting biotic and abiotic
factors that affect community structure. Moreover, competition is not
always a straightforward, direct, interaction. Interspecific competition
may occur when individuals of two separate species share a limiting resource in the same area. If the resource cannot support both populations, then lowered fecundity, growth, or survival may result in at least one species. Interspecific competition has the potential to alter populations, communities
and the evolution of interacting species. On an individual organism
level, competition can occur as interference or exploitative
Direct competition has been observed between individuals, populations
and species, but there is little evidence that competition has been the
driving force in the evolution of large groups. For example, between
amphibians, reptiles and mammals
