Hi All, I would like to draw your attention to a new technique for tracking fluorescently marked organisms from significant distances (at night). The technique uses powerful, handheld, wide-beam purple laser, conventional fluorescent marking (e.g. fluorescent powder) and specially designed protective goggles. We found it very efficient for spotting marked insects in tree canopies (30 meters above ground) and in aquatic environments (the laser penetrates water really well and could therefore also be used for detecting fluorescent fish tags).
