BIO205H5 Lecture Notes - Lecture 8: The Red Dot
Document Summary
Slide #4: can use maps to analyze population, gives temporal distribution of the species, look at the range of a species, gives idea of geographic spans, just describing the range ddoes not give the full detail about distribution. It does not mean the species are equally distributed. Slide #5: there are areas where population is denser than other areas. Which would mean that the population is bigger. Slide #6: clustered --> closer resources, evenly spaced --> regular dispersion pattern. Each bird (refer to pic) protects its own space: random --> as the wind blows. Slide #7: organisms also disperse from their original space, clicker q: who spread so quickly o humans (already on land so no the a) o a infectious disease ( the rate was too slow). o o. A bird species (birds can disperse a longer distance) right answer --> In 60 yrs went all across north america. o an amphibian species.
