Dr. Jennifer Hamel, a behavioral ecologist, joined the laboratory of Dr. Christine W. Miller as a Postdoctoral Associate. Dr. Hamel received a B.A. in Russian studies and Art from Carnegie Mellon University in 2004. She conducted post-baccalaureate studies in Biology at University of North Carolina-Asheville. She received her Ph.D. from the University of Missouri in Biological Sciences in 2011.
Dr. Caroline Williams joined Dr. Dan Hahn's laboratory early last month as a Postdoctoral Associate. Dr. Williams hails from New Zealand (though she is often mistaken for an Australian, much to her chagrin), where she completed her B.Sc. and M.Sc. in the Zoology Department at the University of Otago, working on the physiological mechanisms of amphipod host manipulation by a mermithid nematode (Williams et al. 2004 Funct Ecol 18:685). She recently completed her Ph.D. research in Dr. Brent Sinclair's lab in the Department of Biology at the University of Western Ontario, Canada. There, Caroline studied the effects of climate change on the overwintering energetics of Lepidoptera. Much like Caroline's recent move from Ontario to Florida in January, winter warming is often predicted to bring relief from the bitter cold of winter. However, for ectotherms, body temperature determines metabolic rate, and so any increase in temperature increases metabolic rate, which in turn means ectotherms will burn through energy reserves faster. In addition, many overwintering ectotherms begin the winter with a set amount of energy, which must not only sustain life throughout the winter but must provide fuel for the rest of the lifecycle to resume in the spring. Therefore increases in winter temperature mean ectotherms run the risk of running of out fuel during the long winter dormancy. By subjecting a range of butterfly species to the amount of warming that is projected over the next 100 years, Caroline found that susceptibility to the negative effects of winter warming differed among species, and could to some extent be predicted by species traits such as distribution and abundance of species. Species that were good at mitigating the negative effects of winter warming showed the ability to suppress their metabolic rate in response to warmer temperatures. Caroline's new project here in Entomology and Nematology at UF is to investigate the physiological and biochemical drivers of cold adaptation in Drosophila melanogaster. Caroline is a broadly interested biologist who likes to talk about thermal adaptation and tolerances, stress physiology, and the impacts of climate change on biota, among other things. When not at work, Caroline loves spending time with her two-year daughter Liana, and is enjoying getting out and about in the beautiful natural areas that Gainesville has to offer. She is based in room 3007 or in the Hahn lab—feel free to stop by and introduce yourself!
Dr. James P. Cuda was interviewed by a reporter for the Canadian public television program "Bugzilla." The focus of one the upcoming episodes is the giant water bug Lethocerus indicus in Thailand. The program will be aired later this year on BBC America and the Outdoor Life Network.
Ph.D. student Ericka Machtinger, current and former M.S.student of Dr. Norman Leppla, was the recipient of the department's "John A. Mulrennan, Sr. Outstanding M.S. Student Award." The Mulrennan award includes a cash award of $500. Mrs. Machtinger's thesis was selected to be the departmental M.S. thesis nominee for the College of Agricultural and Life Sciences' "Award of Excellence for Graduate Research."
The following entomology undergraduates made the Dean's List for Fall 2011: Garrett Aronson, Christopher Bibbs, James Fleming, Carolyn Huntley, Zachary Miles, Mary Reed, Anthony Riggio, and Lauren Stewart. To earn a spot on the Dean’s List, students must achieve a 3.70 GPA or higher for a minimum of 12 graded credits.
Christopher Bibbs was also recognized on the President’s Honor Roll for Fall 2011. This recognition requires a 4.0 GPA with a minimum of 15 semester hours of graded credits. Chris also holds down a part-time job in our department's Nematode Assay Lab.
The University of Florida Explorer newsletter featured Entomology as a major this semester and included a photograph of some members of the undergradate Entomology Club. This newsletter goes out to all exploratory majors at UF. If you know of anyone interested in majoring or minoring in Entomology, please advise them to come see me. I know you are the best recruiters for the program. - Dr. Rebecca Baldwin, Undergraduate Advisor
Another UF entomologist was recently featured in a ScienceDaily news release. Lepidopterist Dr. Delano Lewis (Ph.D. 2010), is the lead author of a study which demonstrates that a key amino acid essential for human nutrition is also an effective insecticide against a caterpillar, the Lime or Citrus Swallowtail, that threatens the citrus industry. The article was published in the current issue of the Journal of Economic Entomology. Co-author Dr. Bruce Stevens, professor of physiology and functional genomics in the UF College of Medicine, discovered the pesticide properties of methionine while cloning genes that regulate amino acid metabolism in 1998. Working with Dr. James Cuda, Stevens later found this amino acid to be effective against yellow fever mosquito larvae, tomato hornworm and the Colorado potato beetle. In 2004 and 2007, Stevens obtained two patents for the use of methionine as a pesticide, through the UF Office of Technology Licensing.
Dr. Emily Saarinen (Ph.D. 2009) says that she made it through her first semester as an Assistant Professor at the University of Michigan-Dearborn. Dr. Saarinen is in a tenure-track position and her time is split between teaching courses on Ecology and Environmental Science. She will also be teaching Invertebrate Zoology in the future. Currently, her research is on the conservation genetics of threatened insects. Before taking this position, she worked on climate change modeling in a one-year postdoctoral position with the U.S. Environmental Protection Agency in Oregon. After graduation she had worked at UF's McGuire Center for Lepidoptera and Diversity.

Before the age of IPM, how did a loving mother protect her children from those dastardly insects? Click here for details.
"Butterfly gardens, it turns out, are not all they are cracked up to be, yet many books have been written advocating their existence. Conversely, wasps, ants, and even bees are generally greeted with the question, ‘How do I rid the garden of these threats?' I'm here to suggest instead that a better question might be, ‘How do I live with or encourage bees, wasps, and ants into the garden?' Hymenoptera (as well as other insects) provide four basic services to a garden and the world we live in: food to attract critters such as birds, lizards, and frogs; balance to maintain their own ecosystem; pollination to produce seeds, fruits, and vegetables; and recycling to reuse organic wastes." - Eric Grissell, in Bees, Wasps, and Ants
