Yоu аre wоrking with lоcаl conservаtion agencies to monitor a key population of javelina living in the Sonoran Desert (pictured below). Previous studies estimate that the population can grow unabated - due to numerous resources in relatively new habitat for javelinas. You estimate the population size of javelina in this area to be 80 individuals in 2009 and 130 individuals in 2010. Based on this information, estimate the number of javelina in the population in the year 2011. If your calculation has decimals, round up if your decimal is 0.5 or larger, round down if your decimal is below 0.5. Hint: start by calculating r for 2010, then use the appropriate growth formula to find what the new population size will be in 2011. Because this is a population without an apparent carrying capacity, you should use the exponential growth model.
