Can you identify life history traits that tend to be associated with r-selection and K-selection? The giraffe's stature can be a disadvantage as wellit is difficult and dangerous for a giraffe to drink at a water hole. That means giraffes can afford to be pickier than most big animals, and they're also better able to cope with droughts than smaller animals, as the tallest trees tend to have the deepest roots that reach down to water that other trees can't access. Giraffes aren't predators, so they don't kill other animals, but their huge skeletons require more calcium and phosphorous than they can get from a strictly vegetarian diet.

(c) time Apopulation of giraffes on a square kilometer of the african savannah contains sixteen individuals. The researchers hope that both giraffes will show up again soon. Some scientists contended that these animals could be divided into six or more species, since studies had shown that differences in genetics, reproductive timing, and pelage patterns (which are indicative of reproductive isolation) exist between various groups. Giraffe numbers are 20 percent higher than in 2015, an increase linked to conservation efforts and more accurate survey data. Your friend goes on a mission trip to Brazil.
