Document Summary
Lecture 14 bio220 ecology and evolution of harvested populations. Density-dependent growth rate can limit population size: tern carrying capacity on islands is limited by nesting space, as time increases, n increases until it reaches plateau that reflects capacity that depends on number of available nesting sites. Per capita rate of increase x population size = overall rate of population increase. Ideal harvesting strategy: harvest k individuals/year so population is at maximum growth rate. Improvements in technology make cost curve flatter , but do not alter the population dynamics. Harvesting is determined by: size thresholds, trophy ornaments, e. g. If larger than x gets caught in net, if
