Population Dynamics and Conservation of the Whooping Crane

This video tutorial by Mr. Anderson covers population ecology, focusing on factors affecting population growth, such as density-dependent and independent factors. It explains exponential and logistic growth models, K and R selection strategies, and how to calculate population changes. The video also discusses survivorship curves and species strategies, using examples like the whooping crane and Arctic hare to illustrate concepts.
