NSF awards substantial support for Hibbett’s research into mechanisms of fungal evolution
David Hibbett has been awarded two National Science Foundation grants to support research projects that employ phylogenetic approaches to unlocking the secrets of basic fungal biology as well as the evolution of fungal morphology and ecological strategies.
$275,073 applied over three years will fund Functional and evolutionary bases of substrate-specificity in wood-decaying basidiomycetes . “This project will investigate the mechanisms of substrate specificity and substrate switching in wood-decaying Agaricomycetes using a combination of analyses of genes expressed during decay, and physical and chemical characterization of the decay process. Fungal enzymes that are involved in wood decay or degradation have potential applications in emerging bioprocesses, such as energy-related bioconversions, including biofuel production, and bioremediation. Enhanced understanding of the mechanisms that allow different species of fungi to exploit particular wood substrates could help guide development of genetic resources that could be used for such applied purposes.”
The second grant of $339,384, again over three years, will support Evolution of fruiting body forms in the mushroom-forming Fungi (Agaricomycetes): a comparative phylogenetic and developmental approach. “…much of the basic biology of fungi remains unknown, including knowledge on how fungi develop. This project will address the historical patterns and genetic mechanisms of developmental and morphological evolution in Agaricomycetes, which is a large group of fungi that includes gilled mushrooms, polypores, puffballs, and other complex forms. The results of this research will provide baseline information on the mechanisms of fungal development, as well as gene regulation and other processes of general significance for basic and applied fungal biology.”
Both projects will provide training for undergraduates, grad students and post-docs and will involve educational outreach about fungal biology to high schools and to the general public through a variety of venues. For more information read ....
Fall Fest 2015
Biology and BCMB undergrads presented their faculty-supervised research projects in twenty seven posters representing the biological sciences at this year's Fall Fest celebration. For details check out the Fall Fest 2015 program.
PhD candidate Mandy Gaudreau has recieved recognition via a grant from the Sophie Danforth Conservation Biology Fund for her work investigating the role that pathogen pressure may play in the worldwide decline of frog populations . She will use this award to support her project, "Using species distribution modeling to predict seasonal fluctuations in the amphibian pathogen Batrachochytrium dendrobatidis infection intensity in northeastern United States anuran populations."
The first week of the new academic year was punctuated by the 2015 Bumpus Graduate Symposium on August 26th. Doctoral and masters students presented their research projects with talks and posters, and all were treated to a yummy buffet as well.
...and, if you have fond memories of Where's Waldo, how many Clark biologists can you identify in Professor Robertson's shot of the poster session? Unless our eyes deceive us, we're up to 29 and counting...
Ruela Bardhi, Philip Bergmann, Allan Carrillo, Amy Cheu, Brianna Cooney, Mandy Gaudreau, Chris Grace, Melissa Graham, Faye Harwell, Gina Kelley, Daniel Klonaros, Alicia Knudson, Mitchell Kukol, Denis Larochelle, Becca Littlefield, Neva Meyer, Celine Miranda, Chitra Naidu, Gaby Nemelceff, Marco Notarangelo, Max Nyquist, Nick Pagan, Minoli Perera, Levi Seeley, John Soghigian, Jacob Steenwyk, Abinav Sur, Justin Thackeray, and Simona Tolchin.
On August 5th, Deb Robertson hosted Biology’s first annual One-Slide Undergraduate Summer Research Symposium, a venue for Biology undergrads to practice delivering brief but powerful presentations of their summer research. Rules of the game: presentations were limited to a single slide visual image and a three minute talk. We were treated to four presentations from different labs:
Sam Pelluso and Justin Wilbur from the Thackeray lab presented their research screening for new mutations in the PLC-gamma gene of the fruit fly, Drosophila. This gene is a regulator of development in both flies and humans.
Marian Crockett, who works in the Bergmann lab, reported on her investigation of the effects of solid substrate type (fine/coarse, regular/irregular, etc.) on locomotory modes of lizards moving across different substrates.
Kayli Schulz from the Larochelle lab described her project involving cell printing patterns of Dictyostelium discoidium on bacterial lawns. Kayli is experimenting with the incorporation of flourescence and bioluminescence into her plate cultures to improve the effectiveness of photographic images in showing differential viability of Dicty populations exposed to greater and lesser levels of UV light.
And Monica Marrone from the Livdahl lab talked about her analysis of host-diversity effects on parasite-loading in mosquitos. Her preliminary results point to the occurance of reduced parasite loads in mosquitos collected from communities with higher numbers of mosquito species than from mosquitos collected from communities with fewer mosquito species.
Deb Robertson honored as Outstanding Teacher of the Year
At Clark's 2015 May Senior Brunch, Professor Deb Robertson, pictured here with her students Becca Littlefield and Hannah Reich, was named Clark’s Outstanding Teacher of the Year.
Nominations for this award are provided by department and program chairs and by members of the senior class, who are invited to nominate that full-time Clark faculty member who has had the greatest impact on their intellectual development and academic career inside and outside of the classroom. Following review by the selection committee, all Clark undergraduates determine the "Outstanding Teacher" through a direct, on-line ballot.
Best congratulations, Deb!
Clark University Graduate Student Multidisciplinary Conference

MS Student Does Double Duty as Scholar and Coach
While pursuing her BA in Environmental and Conservation Biology, master’s student Gabriela Jijon Nemalceff became interested in the role of riparian forests on stream systems. With the guidance of John Baker she undertook a survey of macroinvertebrate communities found in the pristine East Branch of the Swift River in Petersham, MA, collecting and sorting specimens of resident invertebrates; her collection enhances the value of the East Branch as a reference stream, used to characterize the baseline ecological condition of rivers and streams throughout the region.
Now pursuing her MS in biology in the Foster & Baker lab, Gaby is building on her survey, identifying the resident taxonomic groups of invertebrates and characterizing their patterns of distribution throughout the system. More specifically she is investigating the effects of riparian land-cover types (meadow/tall grass; coniferous forest; deciduous forest) on the distribution and abundance of invertebrates in the stream system. She is also analyzing the occurrence of morphological feeding types across taxa that may be determined by light and microclimate conditions unique to the different canopy types.
Outside the field and lab, Gaby has an entirely different association with water as a competitive swimmer, both at the international level with the Ecuadoran National Swim Team and at the collegiate level with the Clark Varsity Swimming and Diving team. During her tenure on the Clark team, Gaby set several individual records in various swimming events. Since graduating in 2014 she has broadened her experience of the sport by becoming an assistant coach of the Clark team.
News from Two Livdahl Old-boys...
Robert Koenekoop, PhD '84, MD has been promoted to Professor, with tenure, in the Faculty of Medicine, McGill University in Montreal. Rob, who studied mosquito population biology for his PhD at Clark (in fact he was Todd Livdahl's first PhD student), is Director of the McGill Ocular Genetics Centre and Chief of Paediatric Ophthalmology at the McGill Medical Centre, and has recently developed a successful treatment for a congenital blindness disease, Leber congenital amourosis. His group has also identified a gene responsible for a childhood blindness disorder.
Christopher Vitek, who recieved his PhD in 2003 under the supervision of Todd Livdahl, has received tenure and promotion to Associate Professor at the University of Texas —Pan American. His medical and ecological entomology lab generally studies the ecology and behavior of insects, researching, among other questions, patterns and changes in populations of mosquitos and other disease vectors in the lower Rio Grande Valley, which is an area at high risk for the emergence of vector-borne pathogens novel to the region.
Chris was also recently elected a Fellow of the Texas Academy of Science.
And More from the Current Livdahl Cohort:

In its review of Melissa's proposal the ABS Research Grant Committee commented that “... this is a sophisticated and professional proposal addressing a timely and important question ... (with) results that should be of broad interest and further our understanding of stress response and maternal effects... This an innovative study that may have a huge impact on multiple fields. It is truly integrative as it incorporates animal behavior, evolutionary biology, endocrinology and molecular biology.” In accordance with this assessment, the committee granted Melissa $2,000, the maximum award possible per the Barlow Award guidelines.
M.S. Research Published
Mycologia has just published a paper by 2014 MS graduate Rachael Martin. The paper, coauthored with Romina Gazis, David Hibbett, et al, is derived from Rachael’s master's thesis project ("Unexpected Diversity of Basidiomycetous Endophytes in Sapwood and Leaves of Hevea") investigating the diversity and substrate affinity of fungal endophytes found on wild and cultivated populations of rubber tree plants.
Rachael's research interests were jumpstarted by her work in the Hibbett lab, both as an undergrad and as a master's student. She is currently employed as a Research Assistant in Seanna Annis' lab at the University of Maine, Orono, where she studies diseases of blueberries and their control.
Clark Ureka Award to Biology Student/Enterpreneurs
Christopher Dibble ’16 and Calder Sett ’16 are the first place winners of the Clark 2015 Ureka! Big Idea Challenge. They will use the $3,500 award as startup funds their company, Agraponics LLC, which they describe as an agricultural technology company focused on enabling individuals and organizations to grow their own food using aquaponic and hydroponic technologies.
Their idea for Agraponics sprang from their insight that negative environmental impacts of traditional agriculture and food distribution networks could be mitigated by teaching and empowering small entities, from individuals to communities, to grow food locally. With Agraponics LLC they will design, build and sell simple and elegant systems that will enable individuals and groups to readily produce their own food, from fruits and veggies to fish; and they will provide consultation and education to their customers to teach them how. They are currently developing their product portfolio which will include an array of systems based on various nuances of aqua-, hydro- and aeroponic food production, from very small (Calder has a tiny system growing herbs and lettuces on his desk) to larger systems.
We wish them delicious success.
Recent New Scientist article featuring research conducted in Foster & Baker lab considers a hot question in evolutionary biology: which comes first – adaptation or mutation?
Matt Wund, a former post doc in the Foster & Baker lab, was recently contacted by a writer for New Scientist magazine seeking Matt's insight, based on research he conducted during his tenure at Clark, into the role that phenotypic plasticity may play in evolutionary processes. The New Scientist article considers recent work supporting the proposition that physical changes induced in organisms as a plastic response to environmental conditions can become heritable when mutations reinforcing the plastic response enhance fitness and spread through the population.
Wund’s experiments demonstrated that morphological differences characteristic of two distinct forms of freshwater threespine stickleback (the long, slender head and mouth of limnetic, zooplankton-feeding ecotypes vs. the deep head and short, wide mouth of benthic, invertebrate-feeding ecotypes) can be plastically induced in marine stickleback (the ancestral form of all freshwater stickleback) simply by rearing them on diets specific to either limnetic or benthic environments. His result supports the hypothesis that plasticity may have played an important role in the evolution of stickleback ecotypes that emerged in freshwater lakes and rivers following the recession of glaciers of the last ice age.
Allen Carrillo Baltodano, a PhD student in the Meyer lab, has returned from the annual meeting of the Society for Integrative Comparative Biology where he presented a poster entitled "Reevaluation of the hypothesized loss of segmentation in Sipuncula through in-depth analyses of neural development in Themiste lageniformis." During the meeting he also won the American Microscopical Society's Buchsbaum Photomicrography contest for the best color photomicrograph. Allan's trip to the SCIB meeting was funded by an SBIC Broadening Participation Committee Travel Award.
NEWS FLASH .... Clark Mosquitos Get Second Chance at Space Flight: “Baby Bloodsuckers in Outer Space” Rescheduled for December 16, 2014
The science experiment designed by Columbia Middle School students Lily Walsh, Kasia Kapustka, Julia Ellis, Gia LaSalle, and Bianca Urbina will have a second chance to fly to the International Space Station as part of the Yankee Clipper II payload aboard SpaceX-5, the Commercial Resupply Mission scheduled for launch from Cape Canaveral, Florida on December 16, 2014. The experiment was originally part of the Yankee Clipper payload aboard Orb-3 on October 28, 2014, when the vehicle was destroyed on launch.
The experiment titled, “Baby Bloodsuckers in Outer Space” was selected for launch to space from a pool of proposals submitted by students from the Berkeley Heights School District as part of The Student Spaceflight Experiments Program. SSEP is a remarkable U.S. national Science, Technology, Engineering, and Mathematics (STEM) education initiative that gives students the ability to design and propose real experiments to fly in low Earth orbit.
The winning proposal, “Baby Bloodsuckers in Outer Space” is a student-designed experiment to test the role of gravity in the development of Aedes albopictus mosquito eggs. “We believe the eggs will hatch and mature into larvae even in microgravity. On earth, the larvae float to the surface of water to breathe and mature into pupae”, the students explained. Astronauts will preserve the mosquitoes shortly after they should have matured into pupae during their stay aboard the International Space Station. The students continued to explain, “without gravity […] the larvae will lack a mechanism to rise to the surface and therefore will fail to mature.” The students will also perform the same experiment on Earth in order to observe the differences between both specimens.
The mosquito eggs are provided by Todd Livdahl, Professor of Biology at Clark University.

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.

• 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.
• Deb Robertson received a new NSF grant.
Deb Robertson received a three year award this April (2011) from the Division of Integrated Organismal Systems at the National Science Foundation. The work will examine the role of post-transcriptional regulation of gene expression in marine diatoms.
