Figure 24.10A What Factors Influence Extinction in Small Populations?
Original Paper: Wootton, J. T. and C. A. Pfister. 2013. Experimental separation of genetic and demographic factors on extinction risk in wild populations. Ecology 94: 211
J. Timothy Wootton and Catherine Pfister established new, isolated populations of sea palms (a species of kelp, Postelsia palmaeformis) on exposed rocky shores of the northwestern United States. They then studied the probability of population extinct as a function of genetic structure and population size.
