The microbial food web associated with the ice algal assemblage: biomass and bacterivory of nanoflagellate protozoans in Resolute Passage (High Canadian Arctic)
TL;DR: The results suggest that a shift in the grazing behavior of HNAN occurred during the bloom season, modifying the microbial food web dynamics.

Photoadaptive Strategies In Sea-Ice Microalgae
Raymond G Barlow,Michel Gosselin,Louis Legendre,Jean-Claude Therriault,S. Demers,Rfc Mantoura,Carole A. Llewellyn +6 more
TL;DR: Estimates of the turnover time of photosystem I reaction centres revealed that there was a faster flow of electrons through the electron transport chain in response to the increase in under-ice photon fluence rates.

Carbon flows through the microbial food web of first-year ice in resolute passage (Canadian High Arctic)
Alain F. Vézina,S. Demers,Isabelle Laurion,Télesphore Sime-Ngando,S. Kim Juniper,Laure Devine +5 more
TL;DR: In this paper, an inverse modeling analysis of the microbial food web associated with the spring bloom of ice algae at Resolute Passage in the High Arctic was performed. But the results were limited to two sites under thin and thick snow cover.

An experimental tool to study the effects of ultraviolet radiation on planktonic communities : A mesocosm approach
S. Demers,Claude Belzile,D.R. S. Lean,B. Mostajir,S. Roy,S. J. de Mora,David F. Bird,Michel Gosselin,Jean-Pierre Chanut,Maurice Levasseur +9 more
TL;DR: In this paper, a mesocosm approach was adopted for the study of the impact of UV-B radiation on coastal planktonic communities, and experiments were conducted in eight land-based 1500 1 mesocms.

Impact of freshwater on a subarctic coastal ecosystem under seasonal sea ice (southeastern Hudson Bay, Canada) II. Production and export of microalgae *
Louis Legendre,B. Robineau,Michel Gosselin,Christine Michel,R.G. Ingram,Louis Fortier,Jean-Claude Therriault,S. Demers,D. Monti +8 more
TL;DR: In this article, the relationship between three predictor variables (water salinity, river runoff and seasonal air temperature index) and biological variables are used to assess the impact of freshwater on production and export of microalgae.
