Re: [ECOLOG-L] AIC and Occam's Razor
This might shock some people, bit AIC does not give The Truth. If you have a model that fits almost as well, but is simpler, then I don't see a problem with using it. It's worth checking how much less of the variation is explain (e.g. using R^2), and also how different the fitted models are. AIC has a tendency to give overly complex models (especially with lots of data), so I often use BIC instead, which tends too far in the other direction.

[ECOLOG-L] Graduate student opportunity in prairie ecology/restoration in Nebraska
I am looking for a Ph D student interested in vegetation dynamics in prairie remnants and prairie restorations. The Nature Conservancy has restored 1,500 acres of grassland and manages 2,000 acres of remnant prairies and uses prescribed fire and grazing to increase habitat quality around Grand Island, Nebraska. However, it is increasingly clear that environmental factors such as soil composition and fertility, drought susceptibility, site history and species pools significant influence the vegetation composition. For instance, observationally, we see that remnant prairies are often dominated by invasive grasses and are low in forb diversity. Even when subjected to years of management to suppress invasive grasses and repeated over-seeding attempts, forb diversity fails to increase. Conversely, cropland restorations planted with 150-230 species successfully establish diverse plant communities. However, these restorations are threatened by the same invasive grass species and we see large variation among sites. There seems to be environmental variability, presently unaccounted for, that is hindering successful efforts to rehabilitate remnant prairies and restored prairies. We are currently examining how management (including fire and grazing), site history and site environmental factors correlate with vegetation composition, diversity, and the abundance of at-risk and invasive species. For this we have set up 800 permanently marked plots that are annually monitored for plant composition and abundance. In addition we have data of site history, management, soil fertility, soil texture and will collect productivity, nitrogen and water availability data in the next year. Based on this we will analyze the factors that control diversity, and propose hypotheses for management strategies that increase diversity, decrease the prevalence of invasive species, and increase the abundance of at-risk species. As a next step, we will experimentally examine these hypotheses on factors that controls plant diversity and how we may change the competitive balance among plant species to favor natives, increase the abundance of rare and threatened species, and decrease the prevalence of exotic weeds. If you are interested in such a research project for your Ph D, please contact me. This requires an interest in both basic and applied community and ecosystem ecology.

[ECOLOG-L] AIC and Occam;s Razor
Bob: Here are a few thoughts on your comments: This might shock some people, but AIC does not give The Truth. Of course not; one cannot hope to find full truth from finite samples. If you have a model that fits almost as well, but is simpler, then I don't see a problem with using it. You could use the more simple model if you wished, but it is far better to model average (not to mention that you could properly treat model selection uncertainty as part of the measure of precision). It's worth checking how much less of the variation is explain (e.g. using R^2), and also how different the fitted models are. Adj R-sq might be worth mention; however, it is a very poor way to select models. Adj R-sq applies just to the fitted data set and is not able to reflect out-of-sample prediction. Akaike's predictive likelihood goes beyond this. AIC has a tendency to give overly complex models (especially with lots of data), What you say is correct; however, that is exactly why people should be using AICc -- afterall that was first published some 33 years ago (1978)! so I often use BIC instead, which tends too far in the other direction. BIC is very poor; disliked by likelihoodists and Bayesians alike. Its underlying assumptions are absurd. It is not related to information theory in the slightest. Almost a hoax. This is a poor approach. Or, if the full model isn't too big, I don't bother with model selection, and report the full model. Again, a very poor approach to valid inference unless the sample size is very large. I hope these comments will be useful. David Anderson

Re: [ECOLOG-L] AIC and Occam's Razor
What answers have you found and why were they unsatisfactory? First, use AICc, not AIC. See Burnham and Anderson 2002 or Anderson 2008 (Primer). Second, I think most all literature is rather clear that models with deltaAICc 2 are basically equivalent. So of course you should report support for models in that group, however many there may be. There are plenty of examples in the literature of language to accompany such situations. Finally, if you have this kind of model selection uncertainty, ignoring the advantages of multimodel inference, including model-averaging, is a rather strange decision.

Re: [ECOLOG-L] AIC and Occam's Razor
There are a couple of strange things about the description of the scenario. First, the idea of thinking about a model with almost the same AIC (or, better, AICc) but fewer terms, in pursuit of parsimony is doing parsimony twice. The AIC already accounts for the relative number of parameters. If the model with fewer parameters has a worse AIC, the result is saying that the better model is better even though it has more parameters. And, advantageously, it is doing it in an objective way rather than some subjective feeling about parsimony. Second, in regard to Bob's reply to the scenario, R^2 is a really weak tool for comparing models. You can always improve R^2 by adding more terms. The value of information criteria (or at least one of the values) is escaping from that bind in a satisfactory way. Finally, in regard to Davis's question about what to report, in at least some parts of the literature, it is standard to report all the models evaluated, ranked by their Delta AIC. That way the reader can judge how much better the best model is than the second, third, etc. best. But in the end, you need a model to use. Model averaging is a really good procedure here, and it seems a little strange to rule it out.

[ECOLOG-L] Help with Multiple Regression
Dear friends, It has been recently suggested by Legendre and co-authors that we include quadratic and product terms of our environmental variables in constrained ordinations. For instance, to include not only latitude but also latitude^2 and latitude*longitude, the same with physical and biotic variables aimed at being correlated with ordination axis in some way. I am following McCune and Grace's book (2002) suggestion of correlating environmental variables with NMDS axes. However common correlations of multiple variables x each nmds axis are not the best options because at each correlation they do not control for the other variables in the dataset. Those authors also state that multiple regression use partial correlation coefficients and thus would be a better methos for correlating several environmental variables with ordination axes. However, multiple regression suffers from multicolinearity, which is greatly enhanced when we use product or quadratic terms of the environmental variables. What do you think about that?

[ECOLOG-L] life that uses Arsenic in place of phosphorus
For those who have not heard NASA today announced that research done through their exobiology program discovered a that a bacterium living in Mono Lake, California can use Arsenic in place of phosphorus. This is being pretty hyped in the news as a new form of life. I think the aspect regarding its impact on extraterestrial life is over-hyped and frankly a stretch. We are not looking at an organism THAT USES Arsenic instead of phosporus. We are looking at an organism that CAN OPPORTUNISTICALLY USE Arsenic in place of phosphorus. This is pretty cool, and a huge scientific finding. however, I guess our anti-intellectual society would find it very difficult to appreciate that this is a big deal, so we have to promote the least interesting component of the study, the most speculative, and frankly the part that is hardly related to these findings,...that extraterrestrial life could use Arsenic. In fact, this DOES NOT REDEFINE our understanding of life, it REAFFIRMS our understanding!!! This is another adaptation that evolved from species with normal phosphorus-based physiology that resides in a high-arsenic environment. We long believed that organisms should be able to do this, and now they found one that could. Also, they have not established whether these organisms do this in the environment, only that they can do it in the lab. Understand, I am not taking away from the extreme importance of their findings, I just wish we would actually revel in their findings instead of speculation that has not been established.
