How I Discovered a New German Speech Sound – and Why Nobody Cares

Dr. 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.

Underground Allies: The Crucial Relationship Between Trees and Mycorrhizal Fungi

Dr. Jordon Tourville [Appalachian Mountain Club]. Mycorrhizal fungi form mutualistic symbioses with >94% of all plant species, yet research around their impacts on forests is still in its infancy. Using examples from mountain forests in the Northeast, we discussed how these relationships work and what we still need to understand about these unlikely allies. Watch it here! »

Persistent Pollutants: people and fish

Dr. Celia Chen [Dartmouth]. Environmental pollutants like mercury and "forever chemicals" impact humans and wildlife through consumption of their food. Pollutants come from sources related to human activities and make their way to wildlife and humans through aquatic food webs. Where do they come from, what is their fate in aquatic ecosystems, and what we should do about it? Watch it here! »

Season of the Ticks: Understanding the Spread of Ticks and Lyme Disease in the Northeastern United States

Joseph Savage [Dartmouth]. The presence of Lyme disease and blacklegged ticks in the Northeast results from an incredibly complicated story of ecology. Joseph helped us understand how Lyme Disease has become so widespread, and the pieces that we are still working to figure out. Watch it here! »

There and Back Again: a journey through aquatic ecosystems

Kate Buckman [Connecticut River Conservancy]—There and Back Again: a journey through aquatic ecosystems. Throughout her career Dr. Buckman has worked in various freshwater, estuarine, and marine aquatic ecosystems, traveling from NH to the Caribbean, the deep sea, and back to NH and the Connecticut River watershed. Despite the outward differences between these areas, this journey allowed Kate to observe common threads in aquatic ecology and how humans interact with water. She will talk about her experiences and observations and invites discussion around how our actions here in New England may reach farther than we think. Watch it here! »

Frogs on Tea Bushes and Lessons From Fieldwork

Lilly Linden [Dartmouth]. Dr. Linden will talk to us about some novel genera of frogs from the Western Ghats of India.

Engineering Bacteria for Cellulosic Biofuel Production

Daniel Olson [Dartmouth]. Biofuels made from cellulose are one of the few options available for reducing greenhouse gas emissions in the heavy-duty transportation sector, which includes long-haul trucking, ocean shipping, and aviation. Bacteria that natively consume cellulose are good candidates for producing cellulosic biofuels, but in many cases, their metabolism is poorly understood. Watch it here! »

Life on the edge: alpine plant communities

Dr. 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

Every 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

Did 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

Over 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.

Backyard crickets and tropical katydids: The amazing world of insect sound and vibration

The 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

Many 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

Dr. 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.
