For example, identifying environmental variables that influence gene flow can help us predict how populations may respond to rapidly shifting ecologies in the face of climate change. However, when nearby environments tend to be similar, it is hard to tell whether observed patterns of gene flow are actually controlled by environmental variables, or whether they are just controlled by distance, which is the default expectation. In this talk, I will introduce an update that I developed to the R package BEDASSLE, which is designed to distinguish between these scenarios, called isolation by environment (IBE) and isolation by distance (IBD). My update modifies the underlying model, making the package faster and compatible with larger datasets, and adds a model selection component that directly tests whether IBE, IBD, or both combined, best explains the data. The updated method performed well on my simulated data, suggesting that it could be a useful tool for understanding what shapes genetic structure in populations.\n\nAdvisor: Gideon Bradburd", "occurrence_notes":null, "guid":"148151-21903160@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148151", "building_id":"1005169", "building_name":"Biological Sciences Building", "campus_maps_id":"631", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["Ecology & Biology","Thesis Defense","Graduate Students","eeb","Ecology And Evolutionary Biology","developmental biology","department of ecology and evolutionary biology","Bsbsigns","biological science"], "website":"", "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21903160 } , "146933-21899807": { "datetime_modified":"20260324T085128", "datetime_start":"20260514T170000", "datetime_end":"20260514T220000", "has_end_time":1, "date_start":"2026-05-14", "date_end":"2026-05-14", "time_start":"17:00:00", "time_end":"22:00:00", "time_zone":"America\/Detroit", "event_title":"2026 U-M Neuroscience Conference", "occurrence_title":"", "combined_title":"2026 U-M Neuroscience Conference: Bringing scientists together from across schools, departments and institutes at the University of Michigan to network and celebrate neuroscience.", "event_subtitle":"Bringing scientists together from across schools, departments and institutes at the University of Michigan to network and celebrate neuroscience.", "event_type":"Conference \/ Symposium", "event_type_id":"5", "description":"Mark your calendars for the 6th Annual University of Michigan Neuroscience Conference\u2014a unique opportunity for faculty, staff, postdocs, and students to engage with cutting-edge scientific presentations, participate in poster sessions, and network with fellow university neuroscientists.\n\nDAY 1 - Thursday, May 14 | 5:00-10:00 P.M. \nNorth Campus Research Center (NCRC)\n*Attendees must be 21 years or older\n\nDAY 2 - Friday, May 15 | 9:00 A.M.-4:00 P.M.\nBiomedical Science Research Building (BSRB)\n\nThere will be a poster session and featured scientific talks on both days.
