comment Why aren't plants' roots as diverse as leaves?
PS many of the leaf trait relationships in the paper you cite (Wright et al 2004) were demonstrated to be mathematical artifacts by (Osnas et al 2013).

What do you base your claims that there are only a few ways to be an effective leaf / root on? Evidence would go a long way.

comment Why aren't plants' roots as diverse as leaves?
I think the perceived diversity is biased by the relative obscurity of roots and familiarity of leaves as well as the scale at which a human observes these organs with the naked eye. I suspect functional diversity of roots is greater than leaves. One reason for this is that roots compete for and acquire a more diverse set of resources and interact with a larger diversity of organisms than do leaves. In short, if you could observe the metabolome and microbiome I would expect the opposite to be true.

comment What kind of mushroom is this?
:-) a dog! No, I suspect Coprinus comatus or similar. Did you keep them around? Did they turn black and inky?

Did you try the image search after cropping the fingers out of the target!

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 What are ways to compare the “costs” and “gains” of food production systems?
This is called "Life cycle analysis"

comment What controls leaf senescence in deciduous tree species, and how can I predict it?
there was a related question on stats.SE (about modeling bud burst) stats.stackexchange.com/q/9797/1381

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.

comment How deep in the soil can a seed be placed and still develop into a plant/tree?
there is no single mathematical relationship, but I have tried to provide a general answer please let @richard or I know if you have further questions

@RichardSmith Thanks for looking it over. I just wanted to make sure I didn't miss anything obvious.

TL;DR 1) yes, 2) depends on species, soil, climate, 3) yes

comment Is Homo sapiens the only species capable of prioritization?
Animal behavior is not my field but I think the answer is "no, animal feeding / foraging shows optimization of the cost / benefits of finding and capturing different foods / prey", an ecological 'paradigm' as explained here notes.utk.edu/bio/greenberg.nsf/…
