BIOL 230 Lecture Notes - Lecture 5: Beta Diversity, Species Richness, Gamma Diversity
Document Summary
S = caz logs = logc + zloga y = mx + b y = logs x= loga b= log c z = m. If z=0, s = c(1) = c iclicker: if a sar has c = 0. 2 and z = 0. 25 then: z=1 proportional (linear in linear space) 0 < z < 1: decelerating increase. (i. e. increases w/ decelerating rate) Ans: species increase with area, at a decelerating rate. Larger area -> more individuals -> more species because more resources, less competition. Larger area -> more habitats -> more species. Two things limited the number of species in small areas in scenario 2: low numbers of individuals and few habitat types. Only one of these limited species in scenario 1 (individuals). Between region: different sized areas in different regions. Area number of habitats number of species. Therefore, a region with more habitats has more species in total (gamma diversity = alpha diversity + beta diversity)
