- Hyena carrying capacity in Mkomazi National Park is 500 (in the absence of competitors). Wild Dog carrying capacity in that park is 700 (in the absence of competitors). The addition of 1 wild dog to the park is equivalent to adding 2.5 hyena. The addition of 1 hyena to the park is equivalent to adding 0.4 wild dogs. Which of these species is the better competitor?

These were later determined to be the results of reduced numbers and altered feeding behavior of elk as they were preyed upon by the wolves. Given this information, which of the following best describes wolves in Yellowstone National Park? A. They are a primary consumer B. They are an ecosystem engineer C. They are a foundation species D. They are a keystone species E. They are a flagship speciesExpat Med @DrExpat_ 4.

Unfortunately, thispopulation has underwent an extreme collapse in recent years due to overfishing.Some argue, however, that the collapse of the cod population may actually beattributed to an increase in the population of harp seals, a known predator ofcod. One suggestion to help cod stocks recover is therefore to permit the huntingof harp seals on a large scale. Suggest and explain one potentially negativeconsequence of limiting the harp seal population.A population of 1,492 finches is introduced to a rainforest.
