Survival Strategies

Evolutionary Ecology has 2 Survival strategies:

• r-selection
• k-selection

Differences...

r-selection: many offspring, low investment K-selection: few offspring, high investment

r-selection: expand into open niches K-selection: compete for crowded niches

r-selection: unlimited inputs (e.g. rabbits rarely run out of grass) K-selection: scarce inputs (e.g. predators frequently face starvation)

r-selection: unstable habitats K-selection: stable habitats
