<br />
Suppose that more similar species compete more directly - a very reasonable assumption given the reality of the fuzziness of defining species. Then an LV equation can have species parameterized by "traits." Different "niches" arise naturally in this model. A study of traits in a Panamanian forest suggests that species cluster in trait niches. ''Question'': the niche peaks tend to "repel" each other - is it worthwhile to think of individual peaks as species "quasiparticles" that interact with nearby quasiparticles through some generalized interaction, thereby giving rise to large scale, slow time dynamics?<br />
<br />
'''Otto Cordero:'''<br />
<br />
By creating nutrient beads and immersing them in seawater, colonization by bacteria can be studied in a controlled way. Genomic signatures can be mapped to particular strategies - degraders, cross-feeders, and cheaters. ''Question'': Does the geometry of the beads have an effect on the time behavior of populations? In other words, if instead of spheres, the bacteria were left to colonize tori or sheets, would there be any noticeable differences?<br />

<br />
Interested in when species are able to adapt to new environments. One take away is that species die much more quickly when introduced to high temperatures as compared to low temperatures, and that rate controlled processes have a different functional dependence than regulatory (as a function of temperature). Another very interesting point: it is very common for species from the tropics to invade more temperate climates, but it is much more unlikely for a temperate species from higher altitudes to invade a tropical environment.<br />
