| This article reminded a friend of "Zero to One" by Peter Thiel.
| It was an interesting piece to keep in mind and to make some
| connections while going through the article.

| One note about the trees of Massachusetts is that we chopped 80%
| of them down in the middle of the 1800's, and then for the next
| 80 or so years managed the regrowth depending on what type of
| tree was economically useful. The 1930's aren't that long ago
| from a tree's point of view I think, so we should suppose they
| are still in a fairly perturbed state (both in an emotional and a
| 'different from steady state distribution' sense, I guess).
|
| Anyway, this doesn't really impact the article, which just uses
| the trees of MA as a framing device (narrative framing, that is,
| rather than for example house framing). I just thought it was a
| neat bit of trivia.

| Couldn't that sort of thing level the playing field and alter the
| typical evolutionary processes we would expect?

| Thanks for posting baradhiren07, Brian Hayes is a great find as
| so many theoretical ecologists are so model-oriented their works
| and thoughts are not applicable in forest, field or meadow.
|
| "A model is the Marie Kondo version of nature--relentlessly
| decluttered and tidied up. Sometime important parts get tossed
| out ... Would we learn more if all those aspects of life in the
| woods had a place in the equations or the algorithms?"
|
| I often design very large planting schemes and there are some
| genuinely useful approaches to randomness explored here.
|
| And he's written 'Foolproof, and Other Mathematical Meditations'
| which I'll be tracking down asap.

| I didn't know Brian Hayes has a book too. Thank you for sharing

| Very interesting article. The discussion on the three models and
| their own deficiencies are quite interesting.
|
| Niche assembly: every survival must have its own unique edge of
| advantage. I guess I'm most convinced by this. The counter-
| argument is "how can every specie has its unique edge?", but it
| could also be that we have not yet discovered it.
|
| Natural drift: if everyone is equally fit and the system is large
| enough, then they can all survive (for a long time). But how come
| is everyone equally fit? The response is "since everyone survived
| (as we observe), everyone _must_ be equally fit ".. Honestly I'm
| not convinced by this logic.
|
| Social distancing: trees practice social distancing to defend
| enemies, so diversity comes in. If tree-killing pests are all
| staying on one tree and kill its offsprings around it (but cannot
| kill the original tree since it's too large), then this theory
| seems plausible. I have no idea if this is true in the forests
| though..
