iteroparity semelparity |
Iteroparity:repeated reproducer, organisms that produce offspring repeatedly Semelparity:one time producer iteroparity is favored in more dependable environments, where adultsare more likely to survive and breed again (produces a few relatively large,well-provided for offspring have better chance of surviving and reproducingthemselves). Parent provides provisioning and extra care. Where survival rate of offspring is low (high predation rates, plants that colonizedisturbed environments, etc) , semelparityis favored (produces large number of [small] offspring); |
