Document Summary
What is one density dependent mechanism that could feed back on the growth the size of population rate: disease, resources, predation, predators and diseases (as populations go up, natural enemy pressure could go up even faster, dilution of resources (e. g. oak trees use all the available lights, destruction of resources (e. g. , gypsy moths kill all the oak trees, degradation of resources (oak trees produce secondary compounds) N t= n t ; (t )= log : negative: population is shrinking, greater than 1 = population is increasing. What are the units of nb: nb is a characteristic scale, quantity divided by something, same units as whatever we are dividing with, two ways : e n or e n/n, paramenter that describes the scale over which something interesting b happens. What is a resource that is competed for but not depleted: light, water, nutrients (sometimes, space (e. g. for nesting)
