Adaptation can be considered at the species level, but a recent study involving Tigriopus californicus has shown that that may not be sufficient to accurately predict the effects of climate change on that species. Tigriopus californicus has isolated populations scattered through a wide latitudinal range. These populations have great disparities in terms of their thermal tolerance and their ability to adapt to a new thermal tolerance. This data suggests that in order to accurately predict the effects that a changing temperature and climate will have on a species, it is necessary to look at the variance in adaptation potential in different populations of that species. (If someone could link this week's article and any relevant posts on the wiki I'd really appreciate it. For some reason it won't let me link things on my computer. I'll try to fix it by next week. Thanks.)
