What is behavioral flexibility and is it a mechanism for surviving in new environments?
Behavioral flexibility, the ability to adapt behavior to new circumstances, is thought to play an important role in a species' ability to successfully adapt to new environments and expand its geographic range. However, behavioral flexibility is rarely directly tested in species in a way that would allow us to determine how it works and how we can make predictions about a species' ability to adapt their behavior to new environments. I use great-tailed grackles (a bird species) as a model to investigate this question because they have rapidly expanded their range into North America over the past 120 years. I found that they are behaviorally flexible and that flexibility is independent from problem solving ability, problem solving speed (Logan 2016a), other behaviors (Logan 2016b), and innovativeness (Logan 2016c), and that grackles can solve some problems with a similar efficiency to New Caledonian crows (Logan et al. 2014). I am currently investigating how great-tailed grackles manage to survive in new environments by testing their behavior, immunity, hormones, parasites, and population genetics in three populations from the middle of their range to the expanding northern edge.

Why does brain size vary in the wild?
If brain size does not predict cognitive ability, as I and others have found, then why do brain sizes vary? I have a unique opportunity examine what social, ecological, and genetic factors influence endocranial volume (a proxy for brain size) variation in a long-term dataset of over 1,300 red deer that lived on the Isle of Rum in Scotland. As individuals in the study died over the past 40+ years, their skulls were kept, providing extensive data for each specimen and making it possible to answer previously inaccessible questions about the heritability of endocranial volume in the wild.

My commitment to conducting rigorous science
My goal is to ethically conduct and promote rigorous science. I avoid exploiting myself as a scientist, I facilitate equality and diversity by ensuring that no one is discriminated against when reading my scientific literature, and I keep funds in academia (see my paper and presentation for background). I use the mechanism of transparency to achieve my goal so anyone can evaluate my contributions at every step of the process. I only submit papers to 100% open access journals at ethical publishers, and I publish the review histories (when it is an option) and datasets (and usually also R code) that go with my papers. I only review and serve as an editor for articles at 100% open access journals at ethical publishers, and I sign my reviews. Occasionally, I may submit papers to or review articles for journals that are not 100% open access (but are at ethical publishers) as long as 1) the article will be made open access immediately upon publication (gold OA), and 2) the journal deducts article processing charges from library subscriptions so universities do not pay more than once for the same article.
