SUMMARY:From Glaciers to Gardens: How Earthworms Shaped Northeastern Forest Soils
DESCRIPTION:Join us at the Museum for an illustrated talk by Annise Dobson\, Associate Research Scientist at Yale University\, who will share how the history of earthworms in North America has been shaped by ancient glaciation\, centuries of human-mediated introductions and spread\, and multiple waves of biological invasion.\nThis talk traces that history from the post-glacial forest assembly absent of earthworms and spread of European earthworms through agriculture\, logging\, road building\, horticulture\, and fishing bait. We then examine contemporary invasion of jumping worms\, and how different earthworm groups reshape habitats by accelerating leaf-litter breakdown\, altering soil structure and nutrient cycling\, and changing conditions for seeds\, seedlings\, and fungal communities. Finally\, we consider how earthworm impacts interact with other stressors such as invasive plants\, overabundant deer\, and climate-driven shifts in temperature and moisture\, and we outline practical steps for reducing spread and supporting conservation and management goals. \nWHEN: Sunday\, August 16\, 2026\nTIME: 4-5 p.m.\nPLACE: In person at the Museum and virtual via zoom \nJoin Zoom WebinarAnnise Dobson is the Director of Research Programs\, Associate Research Scientist\, and Lecturer in the Department of Ecology & Evolutionary Biology and the School of the Environment at Yale University. She grew up on a farm in the Ottawa Valley in Ontario\, Canada\, and completed her PhD at Cornell University. Her research focuses on plant-soil interactions and the ecosystem-level impacts of invasive species. Her work investigates the cascading effects of jumping worms on forest health\, from the soil food web\, up to the seedling layer\, and beyond. Dr. Dobson is passionate about translating scientific discovery into practical land management guidance and is actively involved in outreach to help land managers and the public understand and respond to this pressing ecological threat. \nPHOTO CREDITS: Grant Dobson \nJoin from PC\, Mac\, iPad\, or Android:\nhttps://us02web.zoom.us/j/84396919876 \nPhone one-tap:\n+16694449171\,\,84396919876# US\n+16699009128\,\,84396919876# US (San Jose) \nJoin via audio:\n+1 669 444 9171 US\n+1 669 900 9128 US (San Jose)\n+1 253 205 0468 US\n+1 253 215 8782 US (Tacoma)\n+1 346 248 7799 US (Houston)\n+1 719 359 4580 US\n+1 507 473 4847 US\n+1 564 217 2000 US\n+1 646 558 8656 US (New York)\n+1 646 931 3860 US\n+1 689 278 1000 US\n+1 301 715 8592 US (Washington DC)\n+1 305 224 1968 US\n+1 309 205 3325 US\n+1 312 626 6799 US (Chicago)\n+1 360 209 5623 US\n+1 386 347 5053 US\nWebinar ID: 843 9691 9876\nInternational numbers available: https://us02web.zoom.us/u/kb03lgIB1m
