Question

2. An ecologist is monitoring a recently established population of wild lupine (a perennial plant). By carefully mapping, tagging, and censusing the entire population of plants for one entire reproductive cycle (June of one year to June of the next year) the ecologist obtained the following data, use to determine the per capita rate of growth (r) for this population.:

   Initial number of plants: 120

   Number of new seedlings established: 55

   Number of initial plants that died: 15

Answer 1

To calculate the per capita rate of growth (s) for the given population, the following formula could be wed CGR = 5x100 here G= change in size of population le cuerent population - initial population N = intial population t = no. of years. Tune of next * Ча = 1 yeay Given that study period = June of on year to Initial no of plants = 120 Number of new seeding citablished = 55 Number of initial plants that died is Hence current population = (120+55)-15 160 plante i G - 160-120 = $40 plante in CGR = 40 x 100 Pey capita = 33.33% growth rate
