Brain Storming for Meta-Analysis or Literature Review

Hey PAInters,

I thought I would follow up on our discussion yesterday about collaborating for a publication. We could all comment and come up with some ideas on the website and discuss them next week.

From CM:

A general paper on syntheses (e.g., meta-analysis):

    I have been wondering if there is a general rule acknowledged regarding the propensity for dispersal based on a wimpy phenotype. For instance, it seems like the smaller male butterflies, lizards, lions, whatever get the boot because they can’t compete with the bigger males. In butterflies at least, there is some evidence that the smaller phenotype actually has more implicit dispersal ability because of better endurance. So then, is there evidence that these wimpier genes are a higher proportion of gene flow? If so, then this seems like it would be an interesting driver of divergence based on sexual selection (big males would be selected for, but gene flow by smaller males with ensuing increases in heterozygosity would perhaps counteract the initial selection in some way…or just lead to divergence). ANYWAY, the meta-analysis would be is there a phenotypic pattern of who disperses and is there evidence that these are the main culprits in gene flow.

      Hi Josh,

      There are some generalizable “rules.” In small mammals, for instance, there is a pretty strong relationship between sociality and sex-biased dispersal.

      I think that this is a great question. Not to mention a catchy title: “Wimpy gene flow” or “Dispersal of the least fit.”

      I think that you are right about divergence of male body size. I have never read anything about that before. Incidentally I’ve been posed to present a topic for synthesis on size and dispersal. The way I will be proposing to collect data could easily accommodate data to explore this idea. Have you searched empirical or theoretical literatures to see if this has been explored?

    I like Jahner’s idea. I think there is plenty of literature, which would obviously help in the search for data. Dave Wagner just published something on asynchrony in bees

    Another perhaps more tractable idea:

    Patterns associated with host-switching in phytophagous insects. Specifically models of host-switching seem to be built off of the idea that insects are more likely to switch to a congener of their previous host….is this really justified? We could just collate a list of host-switch records and look for patterns…would be pretty easy to do I think.

    Do cryptically colors caterpillars (insects) contain less chemical defensive compounds in their hemolymph than caterpillars (insects) that have warning coloration?

  5. npardikes says :

    The effects of host plant density on phytophage abundance

  6. npardikes says :

    effects of habitat topography on phytophagous insect community structure (diversity or abundance)

  7. npardikes says :

    Is the ratio of predators to victims constant?

    Nick, do you know that you can edit a post? It might be easier to have these all in one.
