Pattern of Population Growth

Factors that Limit Population Size Physical limits

Sometimes other environments are just bad places to live. They may be too hot, too cold, or too dangerous. 

Competition limits

You might have a great place to live but there may be other organisms competing for your food. If there is a smarter bird in the next area, you might not be able to get all of the food you need. A worse situation would be to meet a bird that wants to eat you. 

Geographic limits

You live a good life and might die if you tried to get over the mountains. An ocean might be another geographic limitation.

Equations

This sections seems useless unless the reader is already aware of the identity of each variable. This section needs to define each variable before using it in an equation. Unfortunately I do not know what the variables are and so cannot do this myself, instead I ask that someone with some knowledge in the field add the identity of each variable just prior to their use in each of their equations.

What is population modeling?

"Population modeling is an application of differential equations to the study of changes in populations."

This is not true. Models of population growth might as well consist of difference equations, or be agent based or individual based. --OpenScience (talk) 21:29, 6 February 2010 (UTC)
