This chapter from his Ph.D. reports that in grain aphids, unlike in pea aphids, symbiont Hamiltonella does not appear to confer physiological protection against parasitoid wasps, but parasitoids still preferentially oviposit in symbiont-free aphids. This raises a series of questions on the nature of host-symbiont-parasitoid interactions in this system.|

Karen Sullam has received a Jordan Award from the American Cichlid Association for a total of $1500.
The grant will fund collaborative research with Dr.'s Kilham and Russell, along with Dr. Peter McIntyre from the University of Wisconsin's Center for Limnology. In brief, the work aims to explore the gut bacterial communities of ecologically diverse cichlids from Lake Tanganyika. These fish have evolved different diets over a relatively short timescale. Karen's work aims to determine whether the dietary shifts have been accompanied by shifts in gut commnities. This could suggest a role for symbionts in the remarkable radiation within this group.

Karen Sullam was recently awarded a Fulbright Fellowship to study abroad in the labs of Dr. Helmut Bürgmann and Dr. Blake Matthews at Eawag (the Swiss Federal Institute of Aquatic Science and Technology) in Switzerland. Karen will travel abroad for this wonderful opportunity from September 2011-August 2012.
Jake recently had two NSF grants awarded to study symbionts of ants and aphids. The "ant grant" (more information below) is a collaboration with fellow PI Corrie Moreau (Field Museum of Natural History), and is a three year project designed to examine the role of gut bacteria in the evolution of herbivory across the ants. The "aphid grant" (read below for more information) is a collaboration with Kerry Oliver (University of Georgia) and is designed to understand the forces driving natural dynamics of defensive symbionts and bacteriophage and their natural enemies. The funding will support Yi and Drew's Ph.D research, while also providing support for a postdoctoral researcher on the ant grant.
NSF, DEB—Population and Community Ecology. "Collaborative Research: Inferring bacterial roles in the evolution of trophic level across the ants." $450,00. 2011-2014. (With PI Corrie Moreau from the Field Museum of Natural History)
NSF, IOS—Symbiosis, Defense, and Self-Recognition. "Collaborative Research: Factors shaping the maintenance of variation in a symbiont-mediated host-enemy interaction." $394,119. 2011-2014. (With PI Kerry Oliver from the University of Georgia)
The Russell lab recently hosted visitors from Harvard and the Field Museum of Natural History, for a "mini-conference" on microbial communities of ants. Steffi Kautz and Ben Rubin (from Corrie Moreau's lab) and Jon Sanders (from Naomi Pierce's lab) worked with Jake, Karen, and Yi to address issues in data analyses and to show off exciting results on the bacteria residing in the guts of ants.
Jake and former Russell lab technician, Colin Funaro, published a manuscript in Applied and Environmental Microbiology entitled "Army Ants Harbor a Host-Specific Clade of Entomoplasmatales Bacteria". First author, and former Russell lab technician Colin Funaro, has moved onto NC State where he is working on a Ph.D in Entomology. Co-author, Daniel Kronauer, captured the photo that was awarded the cover of the journal's first issue of 2011 (http://aem.asm.org/content/vol77/issue1/cover.dtl).

Jake, along with Michael Waring (PI) and Shivanthi Anandan (co-PI) were recently awarded a "GRID" award to study the roles of root-associated microbes from "biowall" plants in purifying indoor air. The long-term goal of this work is to engineer more efficient biowalls (living walls of plants) to purify the air we breathe. As such, the 4-story biowall to be installed in Drexel's Papadakis Integrated Sciences Building will provide a great opportunity for future research.
