A former student of mine, noted you were interested in Ring of Fire pubs.  I linked 2 from my lab that are published in international journals:

· Jeziorski, Adam & Keller, Bill & Dyer, Richard & Paterson, Andrew & Smol, John. (2015). Differences among modern-day and historical cladoceran communities from the “Ring of Fire” lake region of northern Ontario: Identifying responses to climate warming. Fundamental and Applied Limnology / Archiv für Hydrobiologie. 186. 203-216. https://doi.org/10.1127/fal/2015/0702 

· Hargan, K.E., Nelligan, C., Jeziorski, A. et al. (2016). Tracking the long-term responses of diatoms and cladocerans to climate warming and human influences across lakes of the Ring of Fire in the Far North of Ontario, Canada. J Paleolimnol. 56, 153–172. https://doi.org/10.1007/s10933-016-9901-7

I have also attached an open-source PhD thesis (Diatoms_as_indicators_of_envir.pdf) which includes the data from these two papers.
