Document Summary
These mega-herbivores were responsible for the structure of the plant community; some. The importance of history and the law of diminishing expectation. Each generation expects less than the previous with regard to saving resources. Incredible biomass of ungulates mastodons, mammoths, carnivores, lions, wolf. The past is the key to the present!!!!: the early pre-european stage: the late pleistocene in north america. The mammoth stepe is a temperature (cool) grassland. The pleistocene overkill hypothesis has been advanced as the cause of the megafaunal extinctions. Humans are the cause to push the mega-herbivores over the edge traits of plants and animals may no longer function as they did then. Many of the plant species had mechanisms that are no longer relevant. Seeds too high for any modern herbivore to eat. Seeds with claws to hitch a ride with an herbivore to be pollinated. When large herbivores went instinct, many plant adaptions were rendered outdated and irrelevant.
