4.If the structures increase the overall abundance of prey in the environment, then they may provide the sustainable new foraging opportunities for these biotas.
6.Thus, the limits on indigenous food production in New Guinea had nothing to do with New Guinea peoples, and everything with the New Guinea biota and environment.
7.Thus, as in New Guinea, the limitations on indigenous food production in the eastern United States were not due to Native American peoples themselves, but instead depended entirely on the American biota and environment.
8.Here, for example, you see biota that colors these amazing hot sulphur springs in New Zealand this gorgeous orange color, and it lets you start to think about how different these other planets could be.
9.We aren't sure why more animals haven't been able to put these microbes to work for them; perhaps it's because their guts don't have the right chemical composition or because other biota already living there are hostile towards newcomers.
