 Name this parameter from population ecology which, for a population experiencing density dependent logistic growth, is constantly decreasing.
ANSWER: r [accept little r, accept intrinsic per capita growth rate; prompt on Malthusian parameter]
 r is 0 for a population experiencing density dependent logistic growth rate when population size reaches this parameter, which is denoted K. It is the maximum number of individuals of a species an environment can support.
ANSWER: carrying capacity
 An organism’s value of r impacts the number of these events it experiences. Semelparous creatures such as the Pacific salmon do this only once in their lives, and an organism’s fecundity describes the rate of this action.
ANSWER: reproductive events [accept words forms, accept equivalents like having kids]
I think this is the sort of thing that Nick and Shan were talking about; hopefully you got a chance to play it [and a few other questions in the set that I think address your comments] at your sites. I was pretty happy with this question, and I'd be glad to hear what you guys think of it. I'm too lazy to post some of the other questions here, but I think the bonuses on E.O.Wilson/Gould/bees, coral snakes/mimicry/sexual reproduction and drift/allele frequency/chi squared are relevant to this discussion also.
