The North American pronghorn has a number of adaptations which allow it to survive in an open plains environment, including teeth and a digestive system specialized to process prairie grasses and shrubs. Found in parts of Southern Alberta, individuals of this species can sustain speeds of up to 80km/ hour, and are known to travel in herds. Cougars, wolves, coyotes and bobcats are their major predators. At one time, herds of nearly 40000000 pronghorn were scattered across North America; now there are fewer than 30000. 3) Provide two examples of specific features of the pronghorn's abiotic environment that have helped shape its physical features and behaviour. Explain each. (2) 4) List and explain one biotic and one abiotic limiting factor that might be responsible for the reduction in pronghorn populations in recent years. (2) 5) A hypothetical terrestrial ecosystem lies near the equator in a region known to receive relatively high amounts of precipitation. What characteristics would we expect this ecosystem to display? Explain (think of the flora and fauna). (2).
