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 ... -
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 ... -
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 ... -
The main nitrate transporter of the dinoflagellate Lingulodinium polyedrum is constitutively expressed and not responsible for daily variations in nitrate uptake rates
(Elsevier, 2016-04-22)Dinoflagellates are unicellular eukaryotes capable of forming spectacular harmful algal blooms (HABs). Eutrophication of coastal waters by fertilizer runoff, nitrate in particular, has contributed to recent increases in the frequency, magnitude and ... -
Exploring dinoflagellate biology with high-throughput proteomics
(Elsevier, 2018-04-16)Dinoflagellates are notorious for their ability to form the harmful algal blooms known as “red tides,” yet the mechanisms underlying bloom formation remain poorly understood. Despite recent advances in nucleic acid sequencing, which have generated ... -
Cytogéographie et taxonomie infraspécifique de l'aster cordifolius L. (Asteraceae) au Québec
(1987-03-31)Le genre Aster (Asteraceae, Astereae) contient approximativement 250 espèces, dont 150 d'origine nord-américaine. L'Eurasie, l'Amérique du Sud et l'Afrique se partagent le reste du genre (Brouillet, 1981). Aster cordifolius L. appartient à la sous-section ... -
The level of pollination specialization affects the relationship between the shape of flowers and the bills of their hummingbird pollinators in Antillean Gesneriaceae
(The University of Chicago Press, 2022-01-27)Premise of research. Pollinators are known to impose strong selection on floral shape. Particularly well studied is the relationship between the flowers of hummingbird-pollinated plant species and the bills of their pollinators. However, no studies to ... -
Le compagnonnage végétal en tant que solution de lutte intégrée contre Pieris rapae, insecte ravageur des cultures de Brassica rapa
(2024-05-22)Les cultures de Brassicacées sont très courantes en agriculture urbaine à Montréal. Elles comportent cependant leur lot de problèmes liés aux insectes ravageurs, tels que la piéride du chou, Pieris rapae. L’utilisation de méthodes de lutte classique ... -
Comportement d’évitement des congénères parasités chez le crapet-soleil (Lepomis gibbosus)
(2024-05-22)Les animaux infectés ont une odeur, une apparence, un comportement et/ou un son différent de leurs congénères non infectés. Ces différences peuvent servir d'indices pour reconnaître et éviter les individus infectés. Des études récentes montrent que ... -
Abrupt shifts in the concentration, composition, and reactivity of dissolved organic carbon along boreal land-water continuum
(2024-05-22)Les sols boréaux représentent l’un des plus grands stocks de carbone terrestre à l’échelle globale. Ainsi, l'un des principaux transferts de matière des écosystèmes terrestres vers les écosystèmes aquatiques concerne le transport du carbone organique. ...
