Quantifying Behavior

Video

The spider FLP group at Las Cruces is learning how to use the MTrack2 plugin in ImageJ and JWatcher software (all free and publicly downloadable). We will be quantifying prey behavior and its effects on predator strikes. It means we get to run around at night hunting ctenid spiders out of bromeliads, and then run around the buildings all day and catch moths like frolicking children. Oh, and watch the giant spiders eat their poor flying victims while we make some very interesting videos. The MTrack2 plugin tracks the resulting binary images to give us coordinates of the prey position so we can quantify their movement with the resulting vectors in a very detailed way (which is super exciting!). Here’s a video of a moth flying to its untimely death.
