Can native caterpillars help control our non-native, invasive plants? That’s what researcher Michael LaScaleia is trying to figure out through his research at the Arboretum. Join us for a Research Spotlight program to learn about Michael’s research and search for some of these caterpillars in the landscape. This walk will include some boggy areas, so waterproof shoes are recommended!
In 2016, the Donald Pfister lab at Harvard University discovered a new species of mycorrhizal truffle at the Arboretum, related to the famed culinary truffle but genetically distinct. Nine years later the lab is still making new discoveries in the field of mycorrhizae: the fungi that form symbiotic associations with plant roots and provide the plants with extra water and nutrients from the soil in exchange for a steady supply of sugars.
Join Professor Don Pfister for a research spotlight on mycorrhizae and the Arboretum truffle, and learn about the biology of mycorrizae, how the Arboretum truffle and other mycorrhizae disperse their spores, and how to go about finding mycorrhizae in the landscape. The group will also take some soil cores and look for evidence of mycorrhizae in the soil. Maybe we’ll find a truffle!
Climate change is impacting every part of the plants at the Arboretum, from the buds down to the roots. Join researcher Nikhil Chari to learn how elevated temperatures and carbon dioxide are impacting tree roots, and the carbon they send back out into the soil. Nikhil will demonstrate how he takes root samples and soil cores, discuss his research on carbon cycling, and compare the root morphology of different plants in the landscape.
Most of us know honeybees for the delicious honey they create (and the occasional sting!). But for scientists, the non-native honeybee represents a potential threat to our native bumblebees and butterflies. Biology professor Dr. Richard Primack has been studying these insects at the Arboretum, observing flower visitors at over 600 plant species to determine if honeybees and native pollinators can co-exist. Just us for a research talk and discover the results of this years-long investigation.
Fungi are known for their decomposing properties, but did you know that also make great building components? Dehydrated fungal mycelium is waterproof, fire retardant, insulating, and sound absorbing, and GSD post-doc Noam Attius is on the hunt for new species of fungi in the Arboretum to create the next generation of eco-materials. Join Noam for a walk in the landscape highlighting her work and learn about the Arboretum fungi she is exploring.
Black swallow-wort is a highly invasive vine in the U.S. and Canada, but in Europe it grows benignly, kept in check by a number of insect herbivores that only live in that part of the world. But what if we could bring one of those insects to New England? Could it control this highly invasive plant? Professor Lisa Tewksbury from the University of Rhode Island has released a number of Hypena opulenta moths in the Arboretum to see if it would control the black swallow-wort here, and now it’s time to return to that part of the landscape and see if the experiment has worked. Join Professor Tewksbury for a Research Spotlight to learn about her work and see if we can find evidence of Hypena opulenta larva on the black swallow-wort plants here.
The Horticulture team planted the Solar Array Pollinator Meadow to provide a habitat for a wide variety of insects, birds, and other pollinators under and around the Weld Hill solar panels. But until recently, they had no good way of knowing just how well their experiment was working–that is, until naturalist Louise Miller took it on as a research project for her Mass Audubon Field Certification. Miller conducted a biodiversity survey of the meadow and recorded 70 species of plants and nearly 300 species of non-plant creatures, from snails and mushrooms to insects and salamanders. Join Miller to learn about the diversity she found here, view some of her incredible photographs, and get a chance to record some observations yourself.
Have you ever noticed the small tufts of hair found at the intersection of veins on a maple leaf? These structures, called mite domatia, provide shelter and protection for predatory mites, which defend the plant against herbivores and pathogens in return. Join University of Michigan Postdoc and 2026 Carvão Awardee Marianne Azevedo Silva to learn about this mutualistic relationship and the research she is conducting on the mites themselves.
