'Cold to tundra' isn't exactly precise. Latitudes above 60 degrees and further north until growing seasons drop below 4 and a half months and thus inhibit the growth of trees, meaning tundra dominates(Original post by love2learn)
so...
rainforests = tropical
deciduous = temperate
coniferous = cold to tundra

thats why soils in siberia etc are so grubs-free, lol; apparently they have no worms, or other living things in the soil cos the soil is too acidic, and has little nutrients/food for any soil dwellers(Original post by Ellie4)

not 100% true...you get coniferous forests in america (i think) and here (but they were intrduced here)...but i think that you can't really distinguish between the layers...its a continuum between coniiferous and temoperate forests i believe, like the rural - urban continuum(Original post by love2learn)

Yeah, podsols are too acidic because of the intense leaching/mor humus/chelating agents, making the horizons pronounced because of a lack of biological agents like earth worms.(Original post by Phil23)

did anyone see that documentary about teh "coldest inhabited place on earth" by that oxford uni tutor? nick or whatevver his name is...
...went to some place in siberia where the coldest temt was -70 something! Its a special microclimate tehy have tehre in between teh mountains where the cold dry continental air sinks.
see geog can be interesting
- just the right things
still think human geog sucks though!

It's not as simple as that unfortunately! I suppose in VERY general terms, that's true, but don't forget climate is different within continental interiors than it is nearer the coasts for example, so there aren't defined bands of forests.(Original post by love2learn)
well tropical then termperate above that and then finally coniferous
