Brett co-authored a paper that appeared in the Journal of Applied Ecology. According to paper’s other co-author, Rufus Isaacs, theirs is the first paper that demonstrates an economic advantage for farmers when they create wild bee habitat next to cultivated fields. The two entomologists planted marginal land surrounding blueberry fields with a mix of native perennial wildflowers. Even though the fields were pollinated by honey bees trucked in for the purpose, Brett discovered that, after a period of two years, the rising population of wild bees increased blueberry yields by 10 to 20 percent. That increase more than offset the costs of making the marginal land attractive to wild bee populations. Brett was the lead author on the paper. The K biology major completed his Ph.D. at Michigan State University under Isaacs and is now working at Rutgers University.

Ellen participated in the April 22 March for Science in Washington, D.C., the goal of which was to send the message that science matters. Ellen was one of six scientists profiled in an April 21 article (“From Alaska to Georgia, Why 6 Scientists Will March on Washington”) that appeared in the Chronicle of Higher Education. Ellen represented the “from Alaska,” where she is a student in ecology and marine biology (her research focuses on humpback whales) at the University of Alaska at Fairbanks. In the article she states that she attended the march, in particular, to make sure that rural researchers and young women were represented. At K Ellen majored in biology and studied abroad in Oaxaca, Mexico. The title of her K Senior Individualized Project is “Tidal Influences on Behavior and Dispersal of Humpback Whales in Glacier Bay and Icy Strait, Alaska.”
Biologist, educator, and “bug geek,” Dan manages the O. Orkin Insect Zoo and Butterfly Pavilion (part of the Smithsonian Museum of Natural History). He contributed his expertise to a recent NPR report (the delightfully titled “How Animals Hacked the Rainbow and Got Stumped on Blue”) about the evolution of the uses of color by animals. Turns out that living and reproducing depended occasionally on an organism’s ability to make itself a certain color. And it further turns out that the color blue was difficult for animals to make by ingesting dietary pigments (many animals get their color from their food). According to Dan, if you can’t make blue, then make the optical technology to appear blue. The entomologist then provides a beautiful example–the blue morpho butterfly, some of which he keeps at his insect zoo. They have tiny transparent structures on their wing surface that reflect light in a way that makes the wings appear so blue it hurts your eyes. But ground up wings, robbed of the reflective prism structures, look gray or brown. At K Dan majored in biology, and his study abroad in Ecuador gave him ample opportunity to pursue his love of insects, a passion he traces back to his freshman year aquatic ecology class. Dan has never forgotten the influence of K on the trajectory of his career. Not long ago he sponsored a K externship at the insect zoo.
Danny continues his publishing endeavors at Skyebluepublications.com of Port Coquitlam, British Columbia, Canada. He plans this year to publish a short review in a peer-reviewed agricultural journal on his research on low-quality feeds and protein utilization in livestock, work he eventually plans to share in book form. He also is preparing two shorter communications: the first on the amino acid histidine fed as a supplement for better growth, lactation and reproduction; the second on models of shell egg cholesterol metabolism for poultry, chicken and turkeys as ways for lowering cholesterol content in the egg. The latter work may suggest new approaches to breeding high-histidine varieties of common animal feedstuffs, including timothy, ryegrass, cocksfoot, fescue, alfalfa, clover, trefoil, sanfoin, soybean, corn and sorghum.
Peter is an associate professor of biology at the Rose-Hulman Institute of Technology in Terre Haute, Indiana. Peter’s research interests include plant-microbe interactions and identification of phytoplasma in wildflowers. He teaches courses in cell and molecular biology, genetics, industrial microbiology, and plant biology. Peter earned his bachelor’s degree in biology and studied abroad in Aberdeen Scotland. After he graduated from K he was awarded a Fulbright Fellowship and studied rainforest ecophysiology at Macquarie Univeristy in Sydney, Australia. He earned his Ph.D. in plant biology at the University of California at Berkeley.
Dan is the subject of “Member Spotlight” for the American Association for the Advancement of Science (AAAS). The article (by Laura Petersen) is titled “Dan Blustein journeys from marine biology to Hollywood and back again,” and it’s a good read, chronicling his interesting forays in the saga explicit in the title–though “back again” might more accurately refer to “marine robotics” rather than marine biology. Of particular note is the reference to Dan’s opportunities in K’s externship program. Those two experiences, one with octopi at the Seattle Aquarium and the other job-shadowing a physician, helped clarify what he wanted to do. Of course the article showcases that Dan’s path has been more spiral than straight line. How cool (and liberal arts!) is that.
Jacob recently completed his Ph.D. at Colorado State University. He has been conducting research on new approaches to control disease-carrying mosquitoes. His research was described in a paper–“Mosquitocidal properties of IgG targeting the glutamate-gated chloride channel in three mosquito disease vectors (Diptera: Culicidae)”–that was published in the May issue of Journal for Experimental Biology. And his paper was highlighted as the “Editor’s Choice” for that issue of the journal. Despite the fact that malaria mortality rates have fallen steadily since 2000, the disease threatens half the human population and kills one child every minute. Moreover, resistance in mosquitoes to the primary pesticide used to control them is increasing. A new mosquitocidal candidate has arisen in an old drug, ivermectin, which has been successfully used against parasitic worms that cause diseases such as onchocerciasis (River Blindness). However, little was known about the process by which ivermectin worked against mosquitoes. Jacob’s research elucidated the site (called the glutamate-gated chloride channel, part of the insect’s nervous system) and the mechanism of action at that site which were responsible for ivermectin’s effectiveness. Based on what was learned from that discovery, Jacob tested a new strategy, essentially substituting for ivermectin an antibody to the glutamate gated chloride channel. His preliminary tests confirmed the antibody insecticide’s effectiveness against the mosquito that transmits malaria. In two other disease-carrying mosquitoes (yellow fever and West Nile virus) the antibody did not pass across the gut, which prevented any insecticidal effect. The next step is to immunize cattle with the antibody. Cattle are a major source of blood meals for mosquitoes. It is hoped that malaria-bearing mosquitoes that consume cattle blood carrying the toxic antibodies during the malaria parasite’s incubation period would die, disrupting transmission of the disease. A new antibody insecticide may offer hope for a malaria-free future.
Jacob is married to classmate Alyssa Brayshaw ’08. This year Alyssa was awarded a prestigious National Science Foundation Graduate Research Fellowship to support her doctoral work. She will begin work in the fall on her Ph.D. at Texas A&M University. She plans to focus her research in the field of wildlife disease ecology, concentrating on Chagus Disease, which threatens to cross the Texas-Mexico border. Jacob was offered and accepted a post-doctoral position at Texas A&M in the lab of a population geneticist studying mosquito populations on Bioko Island and other field sites in West Africa. Jacob majored in chemistry at K. Alyssa majored in biology and studied abroad in Nairobi, Kenya.
Samantha recently served as an AmeriCorps New Jersey watershed ambassador working in the Assicunk, Crosswicks and Doctors Creek watersheds. “I hosted a volunteer monitoring training at the Tulpehaking Nature Center, with eight volunteers,” she is quoted as saying. “We spend many hours together. It had gone so well that I was on cloud nine at the end of the training. I’m so grateful for the time I have spent in New Jersey.” Samantha’s comments were part of the state’s Department of Environmental Protection’s effort to recruit Americorps watershed ambassadors for 2016. Samantha majored in biology at Kalamazoo College and studied abroad in Beijing, China.
