Lecture 6 biological impact of climate change (background) If we turn off conveyor belts of the ocean, we are in big trouble: they are carbon sinks = will release a lot of carbon into the already carbon filled atmosphere. Biological impacts of climate change: niche. The niche space of species may overlap to a greater or lesser extent. Can divide an organism"s habitat to what they need, can be n dimensional, they have a range of temperatures and moisture that they do well in. Can extend to all the variable organisms have to deal with. Fundamental niche: the full range of environmental conditions and resources an organism can possibly occupy and use, especially when limiting factors are absent in its habitat. When two organisms live in the same area with some overlapping of niches, that area is where there will be competition. Is fundamental niche going to be present in the world that is coming: tolerance.
