    Hi Mark. I would be interested in hearing your thoughts about what data could be used to assess detectability and general "ease of study" for a species to address the Research Wish you authored. I am planning on applying for the Rubenstein Competition primarily to address another Research Wish (identifying species traits associated with vulnerability). However, it seems like your Research Wish could be addressed using much of the same data required for that Wish so I was thinking of proposing to address both in my application. I think it would be fairly straightforward to identify species that should be targeted for study (e.g. those that are Data Deficient on the IUCN Red List but are closely related to species with traits suggesting vulnerability), but such species may not have been studied because they are difficult to study. I think the more difficult task would be to come up with some indicator of how easy the species would be to collect the needed information for conservation. I would of course welcome any additional thoughts you had when authoring the question.

    Hi Barbara, Were you thinking of specific physical or behavioural traits that might be associated with vulnerability to climate change when you authored your Research Wish for the Rubenstein Competition? I am interested in applying for the Rubenstein Competition to address the question you authored. I have most recently been working with marine organisms and I know there are several marine species traits that seem to be associated with vulnerability to exploitation and/or habitat degradation (e.g. age at maturity, body size, fecundity, trophic level, speed of growth, pelagic vs. demersal behaviour, and longevity). As part of my PhD dissertation I also tested whether there were any relationships between vulnerability (to exploitation or habitat degradation) and individual movement (swimming capability, home range, or dispersal/migration frequency) among marine benthic fish species. There does seem to be a relationship between vulnerability and dispersal/migration frequency but the relationship differs depending on the threat (exploitation or habitat degradation). I imagine these seemingly important traits for marine species may differ greatly from terrestrial species and may differ between animals and plants, invertebrates and vertebrates, etc. Did you have ideas of other traits that could be important in one or multiple taxonomic groups? I would be interested to hear any additional thoughts you had about this question.
