# Population Ecology (AP topics 3.1-3.5) **Activities, labs, assignments:** * Density-dependence demonstration with ball vs. rolling pin * Exponential growth "riddles" * Breaking down the logistic growth model (completed version on Argonet topic) * K- vs. r-selection card sort (answer key on Argonet topic) * Human survivorship curves lab # Population growth dynamics (basically module 16) **Population growth models:** * **Exponential growth:** * Assumes unlimited resources * Population growth determined by intrinsic growth rate/biotic potential (maximum possible growth rate) * J-curve * **Logistic growth:** * Incorporates limiting resources and carrying capacity (maximum population size that that environment can support) * S-curve **Factors that limit population growth (affect individual survival probability):** * **Density-dependent factors** * **Density-independent factors** **Impacts of resource availability on population growth:** overshoots and diebacks # Module 15: a hodgepodge of population content
