Ants and Plants with Extrafloral Nectaries in Fire Successional Habitates on Andros (Bahamas)
Honey baits were used to assess the activity and abundance of nectar-drinking ants in fire successional habitats of rocklands on Andros Island, Bahamas. Vegetation was sampled in pineyard and coppice habitats (the same communities as Florida’s pine rocklands and hammocks), revealing a larger proportion of taxa with extrafloral nectaries in coppice samples, but roughly equivalent cover of plants with extrafloral nectaries in pineyard and coppice vegetation. Ant activity was greater in pineyard than in coppice habitats, with time to discovery of baits the shortest in open and recently burned pineyards, and most of the baits experiencing recruitment of ants. Overgrown pineyards and coppices both had longer time-todiscovery and much less recruitment to baits; coppice edges, more variable, were not significantly different from either of the 2 other habitat groups. Our preliminary study revealed some new records of plant genera and species with extrafloral nectaries, but all ants we observed at nectaries and on baits are also known from pine rocklands and hardwood hammocks of south Florida
Tan Your Skin, Not Your Eyes
Objective. The goal of this project was to evaluate the public’s use of protective goggles while using a tanning booth and to educate tanners about the harmful side effects that ultraviolet (UV) radiation can have on their eyes. Background. UV exposure increases the risk of certain ocular problems. UV exposure has been shown to hasten a number of serious eye diseases including but definitely not limited to: the development of cataract, pterygium, photokeratitis, age related macular degeneration, conjunctival carcinoma, and malignant melanoma. The signs, symptoms, and effects of such conditions range from dry, irritated eyes to unaesthetic growths on the eyes to decreased vision to even death. Simply wearing the proper goggles would provide ample protection to the eyes from the threats of UV radiation. Methods. We surveyed professional students in the Optometry, Dental, and Osteopathic Medicine programs of Nova Southeastern University. Only students who have ever used a tanning bed filled out the survey and received an informative flyer. Results. A total of 91 surveys were completed. The majority of respondents (63%) report using goggles every time they tan. The rest of the tanners surveyed (37%) report removing their goggles at least some of the time, with almost one sixth (16%) reporting that they never wear goggles
