Ecology on Khan Academy: Why are polar bears found only in the Arctic? Why does mildew grow in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environment, and how these interactions affect where, and in what numbers, different types of organisms are found.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

At the population level, rabbits can have high fecundity:- does this imply an absence of density dependent effects? Or perhaps since rabbits seek to maximize r, the effect would make itself felt on their survivability?

Sir , if I'm correct isn't fecundity the maximum no of offsprings the organism can bear in ideal conditions vs fertility which is no of offsprings under normal environmental conditions.

Would you say that semel parity species have "very low" fecundity, or, "no" fecundity?

Semelparous species may have high fecundity during their singular respoductive event--a lot of their energy is allocated into growth and said event. Salmon are an example of a semelparous species with high fecundity.
