    Why would we expect dopamine to reduce predator adaptation? Does it have something to do with learned fear responses? If so, do these crabs know what an eagle looks like? If they’ve been raised in captivity, how do they recognize a picture of an eagle as a threat?

    I’m interested in the basis for your theory that increased dopamine would enhance habituation. You say that dopamine is linked to associative learning, but did you find any literature on non-associative learning like habituation? Off the top of my head, I think that some literature shows that increased dopamine is correlated to slower habituation (which would be consistent with the pattern of your data) although that has often been attributed to increased locomotor activity as opposed to true habituation.

    HI,
    It was interesting to find out that your study was leaning towards dopamine precursor having a negative influence. Do you think the type of breed and ecosystem conditions have influenced this? I think this study would be interesting to see in different ecological conditions.Great presentation!
