Lately I've been trying to think about what I learn in my classes in a broader sense. What's the "big picture" of what I'm learning? How am I going to use this in the future?
Which brings me to the first of this installment: what I've learned in ecology.
- Bears aren't hibernating anymore! Well, they are, but for shorter amounts of time. They've been slowly migrating to more urban areas, where they have ample food sources from all the garbage they get into. This is why National Parks have bear-proof garbage cans--it really messes up their psyche and hibernation patterns.
- The current population boom is not happening in the USA--it's happening in pre-industrial societies (such as Africa and rural parts of Asia) where new technology is lowering the rate of infant mortality
- You want to see something interesting? Check out wikipedia's page on overpopulation. In a nutshell, we don't know when Earth will reach its carrying capacity (when we don't have enough resources to cover everyone on the planet), because there are so many factors and variables that would determine this statistic.
- Clown fish and angler fish are the coolest animals ever. Clown fish change their sex during their life. For angler fish, the male is teeny tiny and bites onto the female. She ends up sending out a chemical that dissolves the male until he's only a pack of gonads so she can reproduce. So weird!
