How I Discovered a New German Speech Sound – and Why Nobody Cares
April 01, 2025Dr. Simon Stone [Dartmouth]. Computer science meets linguistics in this mashup. Simon invited led us on a trip into speech science research from both an engineer’s and a phonetician’s perspective. We explored how humans produce speech, how we scientifically describe speech sounds, and how engineers translate them into technical systems to learn more about this amazing human ability. Simon told a story of how he once worked at the intersection of multiple disciplines in the broader field of speech research, and how it ironically made it more complicated for people from these disciplines to hear what each other had to say.

Life on the edge: alpine plant communities
April 06, 2021Dr. Simone Whitecloud's (U.S. Army Corps of Engineers' Cold Regions Research and Engineering Laboratory [CRREL]) research uses experimental approaches to investigate the competitive and cooperative (synergistic) actions of plants in the White Mountains (where 30% of the vegetation is left over from the last ice age) and the Arctic. Do different plant species actually facilitate each other in harsh environments by modifying soil moisture or moderating the localized effects of weather? Watch it here! »
Community-based conservation of migratory amphibians
February 04, 2020Every year, on the first warm, rainy nights of spring, thousands of salamanders and frogs emerge from their winter retreats to make their way to nearby vernal pools to breed. Unfortunately, many individuals are killed when their journeys take them across busy roads. Brett Amy Thelen of the Harris Center for Conservation Education joined us to describe her longstanding citizen science effort to document and reduce migratory amphibian road mortality. This effort recently resulted in New Hampshire’s first “Big Night” road closures to provide safe passage for amphibians. Watch it here! »
The conservation status and uncertain future of Vermont's native bees
March 03, 2020Did you know there are over 300 species of wild bees in Vermont? At least, that's the current estimate - but since there has never been a full survey of the state’s bees, it is very difficult to know whether Vermont's bee populations are healthy or declining. Enter the Vermont Wild Bee Survey (VTBees). This ambitious, multi-year project represents the first step in assessing bee populations across Vermont. Last summer, the VTBees team collected more than 9,000 specimens throughout Chittenden County. Then, in an effort to build a comprehensive database of Vermont's bee fauna, the team spent the winter tracking down specimens in museums around the state. They found many surprises in 2019, and they’re certain many more are yet to come. Spencer Hardy of the Vermont Center for Ecostudies joined us to discuss all things buzzy and fuzzy, and to dish out the inside scoop about the trials and tribulations of studying bees, and the current status and future plans of the VTBees project.

Stone tools: exploring the lives of New England's first human inhabitants
January 08, 2019Over 12,000 years ago what would become New England was a very different place. Open tundra in place of forests, huge herds of migratory caribou replacing our familiar whitetails and moose. This was the world of the Paleoindians, the first human populations to settle this area. While our knowledge of these first Native American groups is limited to stone tools, these materials can help us understand life during the Ice Age here in our own backyard. Dr. Nathaniel Kitchel, Dartmouth College. Watch it here! »
Monarch butterfly migration and the power of citizen science
March 05, 2019Known for its beauty and spectacular migration, the monarch butterfly is Vermont’s state insect. Last summer the butterflies were unusually abundant, but during the past decade they’ve become increasingly rare. What’s behind the fluctuations we see in monarch numbers? Elizabeth Howard, Journey North. Watch here! »
A Tall Order: Studying Giraffe Ecology and Conservation in the Savannas of Uganda
May 07, 2019The future of the giraffe is far from certain: over the past 30 years, giraffe numbers across Africa have declined by over 40%. The causes of this decline are undeniably complicated but dedicated teams of conservationists, researchers and rangers are working across the continent to understand and reverse these alarming trends. Dr. Michael Brown, Dartmouth College. Watch here! »
Backyard crickets and tropical katydids: The amazing world of insect sound and vibration
November 07, 2017The ability to detect, process, and react to cues in the environment underlies nearly every aspect of an animal’s life, from finding mates and food to avoiding predators. Therefore, to understand organisms, we must understand how they recognize stimuli to make decisions and how the process of recognition evolves, diverges, and interacts with ecological context.

Sex, Drugs and Bees: plant chemistry and pollinators
September 09, 2015Many plants rely on flower visits by pollinators such as bees in order to reproduce. When bees consume nectar and pollen, they must cope with naturally occurring plant secondary chemicals, substances usually associated with plants' defense against herbivores. Why would plants expose their pollinators to these chemicals? How do they affect bee health? And what are the consequences of plant chemistry for pollination of wild and cultivated plants? Leif's talk will draw on his research in Vermont exploring effects of plant chemicals on bumble bee--parasite interactions and bee foraging behavior. He'll also address the importance of wild bees to agriculture and ongoing efforts to halt their decline. Dr. Leif Richardson is a postdoctoral research fellow at the Gund Institute for Ecological Economics at the University of Vermont. He previously completed a PhD at Dartmouth College and served as State Lands Ecologist with the Vermont Agency of Natural Resources. He contributed to the Vermont Center for Ecostudies Bumble Bee Atlas project. He lives in Montpelier. Watch it here »
Presettlement Forests of New England
May 05, 2015Dr. Charlie Cogbill has spent a large part of his career studying a forest that no longer exists: the pre-settlement forest in New England and New York. His primary research tools are archives, located in town halls and other repositories, of land surveys made during the seventeenth and eighteenth centuries. Many of these archives contain “lotting” surveys – the survey by which the proprietors of a new town divided the town into lots, which were then sold or granted to the earliest settlers. At each lot corner, the surveyors tended to place a monument, often a post or stake or a pile of stones. They also routinely made mention of a nearby “witness tree.” Through statistical analysis and a reliance on his background in field ecology, he has been able to paint a detailed and localized picture of what the forests of New England and New York looked like back when those forests were being settled by Europeans.
