Academic Spree Day -- Undergraduate Research in Biology
2012-13 has been a productive year for undergrads engaged in research sponsored by laboratories throughout the Biology Department. Visitors to Spree Day on April 24 were treated to poster presentations by student-investigators of twenty six research projects involving a broad range of topics in biology. We are thrilled to congratulate them for their successes, engendered by their competence, hard work, and enthusiasm.
A Very Good Year for Clark PhD, John Dennehy!
Todd Livdahl reports that his former grad student, John Dennehy (Ph.D. 2003) has been awared a CAREER research grant from the NSF for $764,000 and that he has received tenure and promotion to Associate Professor at Queens College, City University of New York. John's lab focuses on the evolutionary ecology of bacteriophages.
John Soghigian Awarded NSF Grant
Ph.D. student John Soghigian has received an NSF Dissertation Improvement Grant, for a project entitled "Evolution of Parasite-Host Fitness Tradeoffs in a Mosquito-Gregarine System." The $19,707 award will enable John to further develop his interests in coevolution between mosquitoes and their parasites, and will support laboratory research as well as travel for field collection in Taiwan and Hungary.
Clark PhD Robert Scott Appointed New Director of Bonne Bay Marine Station
A former member of the Foster/Baker lab, Bob received his Ph.D. from Clark University in 2000, working on the function of the black nuptial signal found in males of some populations of threespine stickleback. Bob's connection with Clark Biology continues through his participation in the LEEP Sticklegroup. In 2013 Bob and his associates will mentor three LEEP pioneers from the Foster/Baker lab, who will travel to Bonne Bay in Newfoundland to work on projects helping to characterize the stickleback adaptive radiation in stickleback populations found in the shallow, coastal marine waters and lake and riverine freshwater habitats in the vicinity of the research station.
Spree Day - April 25, 2012
As usual this event attracted many students, faculty members and administrators who all came to take part in this festival of creativity and research. Biology undergraduate students discussed their research findings with crowds of visitors.

Student Research Award
Our Biology BA/MA graduate student, and Environmental Science undergraduate Lianne Samalot has received a 2012 Geller Student Research Award. The Albert, Norma and Howard ’77 Geller Endowed Research Awards are intended to support student initiated research projects that advance both our understanding of opportunities for greater sustainability in the human use of resources and the environment, and practical improvements that can be implemented. Congratulations Lianne!
Mini Spree Day '11
Biology celebrated its Mini Spree Day on April 28th. The students in Animal Behavior (BIOL 242) presented the work they did over the last semester. The food was excellent as well as science experience.
Our recent graduate Anna Mazzarella
Anna Mazzarella (’09), MA 2010, has just accepted a Ph.D. Fellowship at the Centre for Ecological and Evolutionary Synthesis (CEES) at the University of Olso, Norway. The goal of the research in which she will participate is Tracking signatures of adaptive diversification during postglacial colonization in threespine stickleback. The project is funded by the Research Council of Norway. The overall aims of the project are to detect genomic regions and phenotypic traits under selection when sticklebacks invade fresh waters. Anna will work with supervisors at the CEES (L.A. Vøllestad, T.F. Hansen, K.S. Jakobsen, K. Østbye) and international collaborators (F. Volckaert, A. Nolte). This is a wonderful opportunity and we are really excited for Anna.
Our biology majors are real heroes!
Three of our students - Mark Benoit, Jason Smith and Alexander Andersen were involved in a rescue operation that actually saved a person's life. We want to congratulate them. To read the whole story click here.
Our MA graduate, Rachel Chock finds opportunity in Chile
Rachel Chock (’07), MA ’08, has accepted a competitive NSF-funded research position in Chile that will begin in June 2010. She will be conducting research with Dr. Loren Hayes from University of Louisiana, Monroe and Dr. Luis Ebensperger from Universidad de Catolica in Santiago, Chile. The researches focuses on social behavior in degus (Octodon degus), and her personal research focus will be on allonursing by this mammal in the lab and the field. This is an exceptionally exciting opportunity.
Our Ph.D. graduate, Lingyan Wang finds her new path in New York.
Lingyan Wang graduated in May 2009, and began working as a post-doctoral fellow in October, in the laboratory of Dr. Sandra Masur, Professor of Ophthalmology, at Mt. Sinai School of Medicine of New York University. She is responsible for the development of three-dimensional culture systems for use as corneal transplants. Good Luck Lingyan!
Welcome back Sohini
Congratulations to Sohini Ghoshroy who finished her dissertation work this past January (2011). We are pleased to announce that Sohini has re-joined
the Robertson lab as a post-doctoral researcher.
This summer, several Biology faculty and graduate students participated in an on-campus workshop to learn effective ways to communicate their research interests and findings to members of the media and the general public (Read more).
A new paper published in BMC Evolutionary Biology
Sohini Ghoshroy, Manfred Binder, Aurelien Tartar and Deb Robertson have a new paper published in BMC Evolutionary Biology titled “Molecular evolution of glutamine synthetase II: Phylogenetic evidence of a non-endosymbiotic gene transfer event early in plant evolution" . In this paper, they examined the evolutionary relationship of glutamine synthetase from eubacterial and eukaryotic lineages and present robust phylogenetic evidence that the glutamine synthetase gene was transferred from gamma-Proteobacteria (Eubacteria) to the green algae early in plant evolution. Although horizontal gene transfer events (the exchange of genes between non-related organisms) are common in prokaryotes (e.g., bacteria) they were thought be a rare in eukaryotes. Genome sequencing and phylogenetic analyses, such as the current paper, have begun to reshape our understanding of the frequency of horizontal gene transfers in eukaryotes, which appear more common than previously thought.
Manfred Binder et al.- new article on mushroom evolution published in Mycologia.

We are very excited to announce the arrival of a new faculty member to the Biology Department at Clark. Our new Assistant Professor is Néva Meyer , Ph.D. Her appointment started at the beginning of 2011/12 academic year. Néva Meyer studies Annelids' development in order to understand how nervous system evolves. Please read more about her work on her lab website.
• New grant for Professor Todd Livdahl
Todd Livdahl has received a $380,000 grant from the National Institutes of Health, for a three year project entitled "Community Diversity and Parasite Dynamics," in which he and his students will conduct experiments to test for the "host dilution" effect, a hypothesized inverse relationship between the number of host species in a community and the success of a parasite infecting multiple hosts. The experimental system will consist of communities of mosquito larvae as hosts of protist parasites.
