Motion detection

In my last post, I promised an update on the experiments that we are currently conducting in the field. While Alex is toiling away (filming lizards while they sprint along a track) in the basement of the station, I have my own experiment underway in one of the bedrooms. I am testing whether moving objects with certain physical properties (e.g., amplitudes) are more effective at capturing the attention of individuals of several species of Puerto Rican anole. This will let us know whether there might be any underlying differences (or similarities) in the motion detection systems of these lizards. I am nearly finished with two species and will let everyone know how it turns out when I know myself! Ok, back to work ...
