Black flies are ubiquitous and important members of lotic ecosystems. Size is known to affect many aspects of their life in the aquatic larval stage, including intraspecific competition for feeding sites. As filter feeders, flow affects their ability to feed and reach sufficiently fast flow. This, in turn, can lead to risky fluid-mediated dispersal behavior(More)
Elastic-recoil mechanisms can improve organismal performance and circumvent the thermal limitations of muscle contraction, yet they require the appropriate motor control to operate. We compare muscle activity during tongue projection in salamanders with elastically powered, ballistic projection with activity of those with muscle-powered, non-ballistic(More)
INTRODUCTION The method used to create a melanoma trainer using simulated back skin is presented. The trainer is intended to be used to teach medical students to identify benign and malignant cutaneous pigmented lesions. METHODS Non-Hispanic and Hispanic white melanoma trainers were created using flexible polyurethane foam and pigmented silicone rubber.(More)
