Document Summary
Bet hedging , environment is variable or unpredictable. All of their energy is committed to reproduction. Smaller organism have higher rate of growth increase and more variable population. Lower densities: high population, higher birth rates, lower death rate. Higher densities: lower population, lower birth rates, and higher death rates. Species that depend on these tress have to travel around to find the populations in large reproductive years. Subpopulations may occupy patches: subpopulation may come to or close to extinct. One of the most difficult types of animals to manage lice long before reproducing. Predator in same community often prey on same species. Prey in the same community may be prey on. 2 individual interfering with others in order to get resources. Compete for resource by one individuals reduce it availability for the others. Ecological niche: total of species abiotic and biotic resource use. Fundamental niche: an organism"s abilities to live in a given abiotic environment.
