With global warming ongoing,are cold blooded animals like reptiles heading more north or south?
Not only cold blooded reptiles. Ranges for warm blooded animals are changing too. The birds have changed their migration times. The problem is that many species are interlocked in a food web. For example, certain caterpillars can only eat leaves at a certain stage of development. When the time for that development changes, the caterpillars that hatch starve to death. They can’t adapt fast enough. Global warming is an ecological nightmare, in many ways.
