1f. The birth rate in the lynx population can be estimated by determining litter sizes. Litter size can be determined by two methods. The first method involves counting the number of placental scars on the uterus of a lynx carcass. A scar is left at each implantation site of a fetus. The second method involves counting the number of degenerated corpora lutea (plural of corpus luteum) in the ovaries of the lynx carcass. Neither of these methods provides a completely accurate value for litter size. Explain why each method produces an overestimation of actual litter size. i. Counting placental scars Counting degenerated corpora lutea ii. 1g. The procedures described in 1f above involved the study of lynx carcasses. Describe one technology that ecologists use to collect data on any live animals.
