Any specifics on what should be put on the note sheet?
I have general information on both biomes, and ecological principles and diagrams. What else?
Be familiar with how to calculate exponential growth. Include some historical events. Know CFCs. I hadn't thought about them, but my last invite test had a ton. Know stuff like global warming/greenhouse effect.
Thank you! :)

We just had our regionals and the ecology test was weirrrd. Isn't the focus supposed to be placed on biomes in North America? There was far too much on it about the Savannah.

I've also seen a lot about the Savannah. The rules say that we will "answer questions involving content knowledge and process skills in the area of ecology and adaptations in featured North American biomes."

It sounds like North American can apply to the area of ecology and adaptations, or just the adaptations, in which Savannah questions are completely acceptable. I guess it's up to the test writer's interpretation of the rules. I'll go submit that as a question at soinc though.

How different are the tests for B and C?

On my cheat sheet I have rainfall, adaptions of animals, and organisms from every biome, because it seems that the two biomes that are focused upon are just as relevant as the other biomes in the tests I have taken. Would formulas be necessary?

the definition for carrying capacity is: "the maximum number number of a certain species that can be sustained in its environment by the available resources" right?

That's the definition I have on my flash cards, and similar, just more complex, than the one on the wiki. Just double check the fact you said number twice. Most definitions you will need are on the Wiki. It is definitely a complete list.

Has anyone used the Shannon index on a test before?

Hmm, that is interesting. I have never seen that before and certainly never encountered it on a test. It seems similar to ecological entropy, which I have heard of (but never had on a test). It seems that the Shannon index was originally designed for communication entropy but can be effectively treated as a way to calculate species diversity (which is different from species richness). As it turns out, it is one of several diversity indices, all of which utilize sigma notation, and some even have integrals. Many event proctors might find these too advanced to include on a typical Ecology test. Despite that, it is still interesting stuff that is worth learning even if you likely won’t be tested on it.
When it comes to the future, there are three kinds of people: those who let it happen, those who make it happen, and those who wonder what happened.
