Exploring r and K Selection in Ecology

Mr. Anderson explains R and K selection, focusing on population growth, survivorship curves, and the characteristics of R and K selected species. He discusses how these concepts apply to real-world examples, such as wolves in Yellowstone and sea turtles. The video also covers the continuum between R and K selection and gender differences in species strategies.

What does 'R' in R-selected species stand for?

• Growth rate

• Recovery rate

• Resistance

• Reproduction rate

What shape does the logistic growth curve resemble?

• S-shaped

• J-shaped

• Linear

What is the carrying capacity in ecological terms?

• The maximum population size an environment can sustain

• The rate at which a population grows
