Question

24. In this sample matrix calculation of Darwin’s elephants, approximated with three age classes, 0–29, 30–59, and 60–89, what does the value 0.9 indicate? ( 0 2 1 ) ? this row is new young female elephants, 0–29 ( 0.9 0 0 ) ? this is newly middle-age female elephants, 30–59 ( 0 0.8 0 ) ? this is newly older female elephants, 60–89 ? This column is existing older female elephants ? This column is existing middle-age female elephants ? This column is existing young female elephants a. 90% of young elephants survive to become middle-age elephants. b. 90% of middle-age elephants survive to become old elephants. c. Young female elephants produce on average 0.9 female offspring over 30 years. d. Male elephants have an average of 1/0.9 = 1.1 mates over 30 years. 25. In Pinot et al. (2016), did density have a positive or negative effect on population growth? a. positive b. negative c. neither d. both
