Refining transcriptome gene catalogs by MS-validation of expressed proteins
(Wiley, 2017-11-19)Protein sequence identification by tandem mass spectroscopy (LC-MS/MS) identifies thousands of protein sequences even in complex mixtures, and provides valuable insight into the biological functions of different cells. For non-model organisms, ... -
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 ... -
Role of organic matter and microbial communities in mercury retention and methylation in sediments near run-of-river hydroelectric dams
(Elsevier, 2021-02-06)Run-of-river power plants (RoRs) are expected to triple in number over the next decades in Canada. These struc-tures are not anticipated to considerably promote the mobilization and transport of mercury (Hg) and its subse-quent microbial transformation ... -
Role of prey subcellular distribution on the bioaccumulation of yttrium (Y) in the rainbow trout
(Elsevier, 2019-12-13)Our knowledge of the processes leading to the bioaccumulation of rare earth elements (REE) in aquatic biota is limited. As the contamination of freshwater ecosystems by anthropogenic REE have recently been reported, it becomes increasingly urgent to ... -
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 ... -
Spatial organization of dinoflagellate genomes : novel insights and remaining critical questions
(Wiley, 2021-08-14)As is true for many other aspects, genome architecture, evolution, and function in dinoflagellates are enigmatic and, in the meantime, continuous inspiration for scientific quests. Recent third-generation sequencing and Hi-C linkage analyses brought ... -
Spatially explicit predictions of food web structure from regional-level data
(The Royal Society, 2024-07-22)Knowledge about how ecological networks vary across global scales iscurrently limited given the complexity of acquiring repeated spatial datafor species interactions. Yet, recent developments in metawebs highlightefficient ways to first document possible ... -
Toxicity and subcellular fractionation of yttrium in three freshwater organisms : Daphnia magna, Chironomus riparius and Oncorhynchus mykiss
(American Chemical Society, 2019-08-15)The demand for rare earth elements (REEs) has increased since the 1990s leading to the development of many mining projects worldwide. However, less is known about how organisms can handle these metals in natural aquatic systems. Through laboratory ... -
A transcriptome-based perspective of cell cycle regulation in dinoflagellates
(Elsevier, 2016-10-17)Dinoflagellates are a group of unicellular and generally marine protists, of interest to many because of their ability to form the large algal blooms commonly called “red tides”. The large algal concentrations in these blooms require sustained cell ... -
A transcriptome-based perspective of meiosis in dinoflagellates
(Elsevier, 2019-08-01)There is increasing interest in the possibility of sexual recombination in dinoflagellates, especially those symbiotic with coral, since recombination may be able to augment genetic diversity and reduce levels of coral bleaching. Several previous studies ... -
Understanding food web mercury accumulation through trophic transfer and carbon processing along a river affected by recent run-of-river dams
(2021-02-03)Unlike large dams which favor methylation of Hg in flooded soils over long periods, run-of-river dams are designed to flood a limited area of soils and are therefore not expected to significantly affect mercury (Hg) cycling or carbon processing. We ...
