Kudos to Biology Major Phi Beta Inductees and Sophmore Prize Winner!

Congratulations to Biology majors Dylan Cahil '18, Kennedy Jensen '18 and Nicholas Norwitz '18 on their induction into Dartmouth's Alpha Chapter of Phi Beta Kappa!  Dartmouth Phi Beta Kappa inductees must have one of the top twenty cummulative grade point averages after completing eight terms of study at Dartmouth.

Biology major, Anant Mishra '19 received the Phi Beta Kappa Sophmore Prize for holding one of the highest grade point averages in his class.  Congratulations Anant!

Bacterial Classification May be More Elusive than Previously Thought

Prof. Olga Zhaxybayeva's work on the classification of microorganisms has revealed that classifying microorganisms is more complicated than previously thought.  Her paper, A null model For mcrobial diversification published in Proceedings of the National Academy of Sciences of the United States of America, shows that a simple birth-death cycle of cells may explain grouping patterns.

Sound Matters: Sex And Death In The Rain Forest

National Public Radio interviewed Dr. Laurel Symes, Dr. Sharon Martinson and Prof. Hannah ter Hofstede about their research on the sounds of the rain forest.  The group is studing the complex ultrasonic communications of bats and their insect prey.  The read or hear the full interview please visit the NPR website at the following link:  https://www.npr.org/2017/04/04/521452464/sound-matters-sex-and-death-in-the-rain-forest

Aldo Arellano '17 Studies the Ecology of Lake Mývatn

Undergraduate researcher, Aldo Arellano '17, spent last summer studing the ecology of Lake Mývatn in Iceland.  Aldo was selected to be one of four researchers to go to Iceland under the National Science Foundation's Research Experience for Undergraduates program.  The project in Iceland took an interdisciplinary approach to understanding midge flies and their influences on food webs.  Aldo's work focused on the blue-green algae, Anabaena.

Laurel Symes, Ph.D. is Featured in Nature Article

Dr. Laurel Symes, Neukom Fellow, is featured in the Nature article, Research Protocols:  A forest of hypotheses.  In her work on sensory perception and decision making, Dr. Symes uses a method called multiple-working-hypotheses.  This method allows her to consider several hypotheses at once rather than focusing in on a single hypothesis.  While this approach requires extensive preparation before the start of experiments and continual refinement of hypotheses during the experiments, it allows researchers to avoid ignoring possible explanations that would be excluded using a single hypothesis.

Dr. Dustin Rubenstein '99 returns to Dartmouth for Scientific Seminar

Dr. Dustin Rubenstein '99, Associate Professor of Biology at Columbia University, returned to Dartmouth in April to report on his research on how organisms adapt to changes in the environment.  While at Dartmouth, Dr. Rubenstein enrolled in the biology department's foreign study program (FSP) and was an undergraduate researcher in Professor Richard Holmes' lab.  His work with Prof. Holmes was published in Science

Dr. Rubenstein reports that his time at Dartmouth continues to influence and inform his work.  His experience on FSP led him to create a field research program at Cornell and later at Columbia based on the FSP model.  The Dartmouth biology department FSP program will celebrate its 40th year in 2017.

Professor Mary Lou Guerinot Elected to National Academy of Sciences

Professor Mary Lou Guerinot has been elected to the National Academy of Sciences (NAS).  Academy members are elected by their peers for outstanding contributions to science.  The NAS has 2,291 active members and 465 foreign associates

Professor Guerinot joined the Department of Biological Sciences in 1985 as an Assistant Professor.  She has trained more than 100 undergraduate researchers and 19 graduate researchers since arriving at Dartmouth.  She has served as Department Chair, Associate Dean for the Sciences and Vice Provost.  Professor Guerinot is the Ronald and Deborah Harris Professor in the Sciences.

The focus of the Guerinot lab is metal and metalloid homeostasis in plants.  Essential minerals play an important role in both plant and human health.  Her lab been a leader in identifying the genetic players and mechanisms involved in iron uptake and homeostasis in plants.  Her worked has been funded by several organizations including the National Science Foundation, National Institutes of Health and the United State Department of Agriculture.

Professor Mark McPeek Elected to the American Academy of Arts and Sciences

Professor Mark McPeek has been elected to the American Academy of Arts and Sciences.  The Academy is one of the oldest learned societies.  Its mission is to serve the "nation as a champion of scholarship, civil dialogue, and useful knowledge."*   Professor McPeeks joins a distinguished group of more than 4,600 Fellows and 600 Foreign Honorary Members.

Prof. McPeek is an ecologist and evolutionary biologist who uses empirical and theoretical approaches to understand the processes that determine organism distribution and abundance.  His work also looks at how processes have influenced organism adaptation and diversification over time.  Currently, he is studying the influence of species interactions on species coevolution and the biological community structure.
