Hi All, I'm seeking a better understanding of the difference in these to widely referenced points of view on niche/trophic assembly.
In an assembly of organisms in a habitat that are seen with Hutchinson glasses, over time one organism in a group of like organisms would have some advantage and slowly (or quickly) use up those resources that the advantage incurs to that organism. With Hubbell glasses, the like organisms in a single trophic level are all essentially the same, even though they are different species. One individual replaces another in the suite of like species when an 'opening' occurs due to death. These very simple charaterizations are the basis for my question. If each species in the group of organisms have specific most critical habitat needs, would they be similar needs or disparate needs, to fall into either the Hutchinson or Hubbell explanation? That is, if all the like organisms of the several species, all were found to have as their most critical habitat requirement to be rainfall in the winter, which explanation would fit best? If some species had winter rainfall, and some summer temperature as their most critical habitat requirement, which explanation is more explanatory? Happy T-day William Espenshade
