In teaching methods, I cover non-linear effects (where the change in Y resulting from X varies by the level of X). I've been looking for a good illustration of it, and lo and behold, I found a very good one for college students.... I bet that my students will better understand the concept now.
The same appears to be true for some plants and CO2 levels. Increased CO2 levels can enhance plant growth (it is essentially plant food), but at a certain point the high levels can begin to affect gene regulation in certain plants, leaving them more susceptible to predation.
ReplyDeleteInteresting... there are a lot of cool non-linear effects in the world (though I think the one about beer might be more relevant for college kids. :-)
