Natural selection and selection by nature

Hi All, I did not foresee to stir such a discussion, but I am glad I did, and the discussion is very helpful, to show that we are using so many different working definitions. I will give my 2 cents on this. First of all, we have to distinguish between "Natural Selection" and "Evolution by mean

Garmin, Magellan, and ArcGIS

I am shopping for recreational-grade GPS units, specifically looking for a unit from which I can import points into ArcGIS with date, time, and notes. Can anyone give me any recommendations for or against any particular units, brands, or data-transfer tricks? Thanks, Joe Sexton

Re: Questioni: what would a bankrupt U.S. government mean for wildlif e conservation

I’ve extracted the following from a draft manuscript about the role of ecologists in macroeconomic policy dialogue. It’s relevant to Ken Bagstad's observations on the "dilemma" facing conservationists vis-à- vis economic growth, which were prompted by Stan Moore. I think one horn of this dilem

Re: Maldaptation, Extinction and Natural selection

Norris, I think you have a good point to illustrate the problem: > Imagine the case where you have two phenotypically identical > populations that have different underlying genetics. If these > populations have different heritabilites, application of the identical > selective pressures could l

Re: Maldaptation, Extinction and Natural selection

Imagine a stable population in which a favorable new genotype has appeared and is increasing. That sure looks like selection FOR the new genotype to me. On the other hand, if we start with the same population and change the environment so some of the old genotypes no longer do well, I'd call th

Re: Maldaptation, Extinction and Natural selection

Part of this disagreement seems to stem from a detachment of ecological processes (death and reproduction) and resulting evolutionary patterns. Various ecological processes act in a non-random ways to remove phenotypes (and indirectly genotypes) from populations. I am hesitant to reserve the t

Re: Maldaptation, Extinction and Natural selection

But Wirt, Natural selection doesn't "cull" but rather it "favors." And selecting "for" something is very different than selecting "against" something. Favoring a trait leads to adaptation. That is, those with a trait leave more descendents. Even so, it is not that simple. At any rate, John
