LIMNOLOGY SEMINAR: Join us on Wednesday for a seminar by Monica Fisher: "Fire Dynamics of northeastern Ontario throughout the Holocene," at 12:30 in Biosciences 4338.

The Cumming Lab is proud to announce that Brian Cumming is the 2019 Rigler Award Winner! A big thanks to @Can_Limnology, the nominator and the selection committee!

Congratulations to #queensu researcher Dr. Brian Cumming who has received the @Can_Limnology Rigler Award sponsored by NRC Canada for lifetime contributions to #limnology, the study of inland waters 💧 Read more: bit.ly/2ZJG0q1 Discover #QueensuResearch

Getting ready to share the 2020 Rigler Award @Can_Limnology at CCFFR. Congratulations to Brian Cumming from Queen's University !

Brian Cumming is up talking abt his research on lake responses to anthropogenic and natural forcings for the Rigler Memorial Lecture. #ccffrscl2020 #ccffrscl

Conceptual basis for need of long-term data: how can research inform what is 'acceptable' environmental change with baselines having shifted over timescales? #ccffrscl2020 #ccffrscl

Case study: Osoyoos Lake in southern BC. Straddles Canada-US border. Sediment loadings caused bacterial blooms starting in 1960s thru to today, corrective measures caused improvement after 2000. #ccffrscl2020 #ccffrscl

But what is baseline? Modern day diatom distributions related to Phosphorus levels, & paleolim diatoms in lake used to understand historic loading, shows climate change affecting it now #ccffrscl2020 #ccffrscl

Case study: reference lakes in Adirondacks region. Chrysophytes used to compare pre-industrial to modern conditions. Most lakes have changed chrysophyte assemblage to warmer water species: shifted baseline to compare to acidified/stressed lakes. #ccffrscl2020

Case study: using paleolim data to get baseline from warmer periods over prev thousands of years in NW Ontario. How representable is monitoring data from 1969-today? #ccffrscl2020 #ccffrscl

Monitoring data since 1960s vs paleolim data show large changes of plankton assemblage starting in mid to late 1800s. Also developed method to sample different depths to account for changing lake depths and plankton shifts relative to shoreline #ccffrscl2020 #ccffrscl

Going back in time with paleo data from canadian lakes and great colleagues during the Rigler Lecture. CCFFR @Can_Limnology Cumming Lab River Institute

The first Rigler award was given in 1984- today one space is left on the plaque ! @Can_Limnology

Congratulations to Dr. Brian Cumming from Cumming Lab Queen's University for winning the Rigler Award for life time achievement and contribution to the field of aquatic science in Canada 🇨🇦 💧 #limnology #canadianscience

Congrats Cumming Lab! I’ll never forget the day we collected that particularly long gravity core!

Join us again next week for a #limnology seminar with Dr. Bjoern Wissel who will speak on DIC dynamics in hardwater lakes! DM myself or Dr. Liz Favot if you’d like the zoom link!
