rooroo17: If you can't sit down, study in sections I guess. For me, I took studying a bit slowly, one or two chapters a day. (:
Gotta say, I love the name.
Because of the short growing season, most tundra plants are perennials.
Short growing season is only half the story. Annual plants have to regrow 100% of their structure and cells every year, making them much more suited for less harsh climates. Annuals can be thought of as being more r-selected: they put all of their energy into producing a lot of seeds after one year and dispersing them all, at which point they die. Perennials put more energy towards survival. They can regrow from pre-existing biomass from the year prior, meaning they need less energy to survive any given year. If you haven't noticed, the tundra is a pretty unforgiving biome. There is very little energy because the sun's rays hit at such an oblique angle. So yeah, perennials are definitely favored. Plus the short growing season thing.

In the rules, it says some questions may be regarding the local ecology at state and regional level. Do you guys think it will apply to invitationals as well?

I suggest the nitrogen, dihydrogen monoxide, carbon, and phosphorus cycles.
Do you think we need to know the sulfur cycle or the potassium cycle? Have you guys ever seen questions on them?

Those two are really simple though. I'm pretty sure they have shown up before on tests, I mean, why wouldn't they? Just memorize them.

Another question: In the tundra, what would be the main limiting factor? I've had many sources say its the temperature and the lack of moisture, but another said it was the short growing season and the permafrost.

Well, the growing season is determined by temperature and rainfall (and sunlight) and permafrost exists because of low temperature.
So, ultimately the temperature, lack of precipitation, and lack of sunlight would be the limiting factors.
