I have my hands on a textbook of biology
I find the current biology in DF lacking. Don't you?
Please add anything else you can think of:
Food webs. - animal eats animal etc
This brings into question the
interaction of different species in their biomes. Not all animals just eat and get eaten by each other.
Carrying Capacity(maximum critter count) designated by the amount of producers(trees and brush) which is dependent on the biome itself. Climatograms

Population Density - I think this is covered in the raws already.
Competition from other animals, Predation, Parasitism and disease, Drought and other climate extremes. Dwarf-caused/"Intelligent being" distrubances to the environment all contribute to
population size.Environments should be always changing. Populations should adapt to a certain amount of change.
... oooooogh
Aquaculture - the raising of aquatic animals for dwarf consumption. tehe?
and simply...
evolution! with a lot of this tied in to it all.
What are your thoughts?
