Relationship between extracellular low-molecular-weight thiols and mercury species in natural lake periphytic biofilms
(American chemical Society, 2015-05-26)The uptake of mercury by microorganisms is a key step in the production of methylmercury, a biomagnifiable toxin. Mercury complexation by low molecular weight (LMW) thiols can affect its bioavailability and thus the production of methylmercury. Freshwater ... -
Increasing phytoremediation efficiency and reliability using novel omics approaches
(Cell Press, 2014-04-12)Phytoremediation is a cost-effective green alternative to traditional soil remediation technologies, but has experienced varied success in practice. The recent omics revolution has led to leaps in our understanding of soil microbial communities and ... -
Effects of experimental thermocline and oxycline deepening on methylmercury bioaccumulation in a Canadian Shield lake
(American Chemical Society, 2014-02-10)Environmental disturbances like deforestation or climate change may influence lake thermal and oxic stratification, thereby modifying cycles of contaminants such as mercury (Hg). In a lake naturally separated into three basins, the thermocline and ... -

Neuron participation in a synchrony-encoding assembly
(2006)BACKGROUND:Synchronization of action potentials between neurons is considered to be an encoding process that allows the grouping of various and multiple features of an image leading to a coherent perception. How this coding neuronal assembly is configured ... -
Forked Three-awned Grass, Aristida basiramea Engelm. ex Vasey : a new addition to the flora of Quebec
(Ottawa Field Naturalists Club, 2004)A population of Forked Three-awned Grass (Aristida basiramea Engelm. ex Vasey; Poaceae) was found for the first time in Quebec, on a sand barren of the Cazaville region (Haut-Saint-Laurent). The only other region where this species is known in Canada ... -

Selecting herbaceous plant cover to control tree invasion in rights-of-way
(Elsevier, 2002)Following construction of a right-of-way, environmental regulation often requires the rapid restoration of a herbaceous plant cover to control erosion and/or attenuate visual impact. Herbaceous species can be selected with the added long-term goal ... -
Biodiversite microfongique du Fagus grandifolia dans une forêt ancienne : bioindicateurs et structure mycosociologique
(Ottawa Field Naturalists Club, 2001)En Amérique du Nord, l’étude de la biodiversité des micromycètes dans les forêts anciennes représente un potentiel incontournable et largement inexploré. Le présent inventaire nous a permis de mettre en évidence la biodiversité microfongique, ... -
Edge effects on vegetation in rights-of-way
(Elsevier, 1997)As a result of an increasing use of ecological methods for the control of vegetation in rights-of-way, it has become necessary to understand the natural processes that are likely to facilitate or hinder management objectives. Several factors may ... -
Une addition à la flore du Québec : Monarda punctata var. villicaulis (Lamiaceae)
(Ottawa Field Naturalists Club, 1994)Une population de Monarde ponctuée (Monarda punctata var. villicaulis) fut trouvée pour la première fois au Québec, dans la région du Haut-Saint-Laurent. Cette population, qui comprend plus d’une centaine d’individus, déplace légèrement la limite ... -
The history and tree stratum of an old-growth forest of Haut-Saint-Laurent region, Quebec
(Natural Areas Association, 1992)An old-growth forest of presettlement origin was recently discovered at the northern limit of the Eastern Deciduous Forest (sensu Braun 1950) of North America, in an area that is extensively affected by logging, land clearing, and agriculture. In a ...
