Reproductive isolation: prezygotic, find a mate, both be fertile, give and receive mating cue, mate and form zygote, post-zygotic, zygote and embryonic development, production of grandchildren, results in hybrid inviability or sterility. In summary, those are things that can hinder the successful creation of offspring. Landscape features that influence microclimate vegetation: there can be huge temperature differences due to shade. Temperatures in aquatic environments: water temperature does not fluctuate as much in marine/aquatic environments as they do on land. Evolutionary tradeoffs: adapting to one set of environmental conditions generally reduce fitness in other environments, you can only really be adapted to a certain range of conditions, tied to . The principle of allocation **: all organisms only have a limited amount of accessible energy, can only eat so much food in a day, and only so much can be processed, evolutionary tradeoffs are inevitable.
