Document Summary
R selection: high growth rate, competitive ability is not strongly favoured, rapid development, early reproductive maturity, small body size, single reproduction event (semelparity) Die right after reproduction: all maintenance energy is allocated to reproduction, many, small offspring. K selection: competitive ability is strongly favoured, slow development, late reproductive maturity, large body size, repeated reproduction events (iteroparity, few and large offspring, categorizing plant life history (life history strategies - triangle, competitive, ruderal, stress tolerant. Competitive species such as birch predominate of low disturbance and low stress. Stress tolerant species predominate under conditions of low disturbance and high stress. Ruderals are dominant under conditions of high disturbance and low stress: species distributions and abundances, size and density relationships. Population = a group of individuals of a single species inhabiting a specific area: characteristics, abundance, density (absolute and ecological), Abundance number of individuals: estimating of, flying insects are harder to detect (have to use a net to capture them)
