To support my research on ecosystem functioning, my collaborators and I are developing PEcAn, a model-data synthesis framework (www.pecanproject.org) and BETYdb, its underlying database (www.betydb.org).

comment What are the ecological effects of moderately high and prolonged concentrations of nitrogen deposition on an ecosystem?
Would help to define magnitudes. Prolonged = decades? Moderately high = 5g/m2/y?

comment Definitions and examples of some math-releated ecology branches
"Numerical Ecology" is the title of a classic text by Legendre and Legendre, with a recent variation applied to R; but it is not clear how the field is different

The question is not answerable unless you define "bad"

comment Relationship between biomass and net primary productivity
What model are you using to predict NPP? What other variables does it predict? How frequent are the biomass measures? does it predict above and belowground NPP separately? You can only compare apples to apples.

This is called "Life cycle analysis"

comment Are there any substance that are more dangerous at low dose than at higher dose?
thanks for the clarification; as written it can be interpreted as "homeopathy" doesn't work, except when it does. On another note (more as a clarification for readers than as a correction to you) the GMO study is a poor example to use. Because of the many flaws, any inference is limited (e.g. my primary conclusion is that there is insufficient information to conclude anything about the relationship dose-response relationship).

Example of something always reactive no matter the dose?

sugar, water, protein, ... these all have an optimal range of healthy doses- too much OR too little can be harmful.

Perhaps the Biofuel Ecophysiological Traits and Yields Database would be of some help?

comment What is the effect of a pure-oxygen environment on a plant?
If the plant is potted, thre could be co2 from the soil, as well as from plant respiration. But at such high o2, photosynthesis would be inefficient.
