How do lichens represent the level of air pollution?

Post by sviestine_muse » Wed Sep 06, 2006 6:58 pm

hello everybody,

although i'm a novice here, i expect some help from you. i have to write an essay (~4000 words in lenght) about how diversity and abundance of lichens represents the level of air pollution in some certain areas. experiments were carried out in two different territories, one very close to an important road and the other quite apart from any traffic. the thing is, i need some external sources of information for my essay, and this is quite a problem. results are gathered and are waiting to be analysed, so if someone could advise me any site or book, it would be perfect and i would really appreciate it :)

by the way, does anybody know how are the types of lichens called in english? i mean those three types: one is lichens that are quite bushy and usually grow in clean areas, the second is lichens that have structures similar to some sort of leaves and the third one is lichens that neither have leaves, nor are similar to a bush. does somebody know what i am talking about?

You're in the IB program and writing an extended essay?

Lol, I'm done :), and I'd suggest you don't do the same paper as the exemplars

mithrilhack> I wasn't given this title as an example, so. Anyway, if such exists... Seems that I am not lucky then :D Did you also write a biological essay? By the way, what subjects did you take? What and where are you studying?

loveangel> International Baccalaureate, a programme in which you take the exams equivalent to GSCE. And a diploma of which is accepted by most of universities around the world :)

As far as I know, the EE is bull, it only helps if you're missing your IB test points(SL). I'd find out what my advisor wants rather than what IB wants since the advisor will give you a school grade(at least at my school it was).
