	abstract = {The justification of the 4 genera that currently compose the class Pavlovophyceae is based on a low number of species and a relative paucity of available, traceable and referenced cultures. Previous integrative phylogeny work revealed strains that can refine and strengthen our knowledge of the genera\&nbsp;in the class. The application of multiple light and electron microscopy techniques allowed us to prioritize\&nbsp;the cytomorphological characters (pyrenoid, thylakoid, stigma, knob-scales, life stage / life cycle) used for\&nbsp;the taxonomy of these algae and to describe two new species:\&nbsp;Exanthemachrysis fresneliae\&nbsp;Véron sp. nov. and\&nbsp;Rebecca billardiae\&nbsp;Véron sp. nov. Consequently, revisions of the two genera\&nbsp;Exanthemachrysis\&nbsp;Lepailleur emend. Véron and\&nbsp;Rebecca\&nbsp;Green emend. Véron were made. In addition, the genus\&nbsp;Pavlova\&nbsp;Butcher emend Véron is revised in the light of these characters. Particular emphasis is placed on the life\&nbsp;stages and habitat of the species.},

	abstract = {<p>The population dynamics of different Pseudo-nitzschia species, along with particulate domoic acid (pDA) concentrations, were studied from May 2012 to December 2013 in the Bay of Seine (English Channel, Normandy). While Pseudo-nitzschia spp. blooms occurred during the two years of study, Pseudo-nitzschia species diversity and particulate domoic acid concentrations varied greatly. In 2012, three different species were identified during the spring bloom (P. australis, P. pungens and P. fraudulenta) with high pDA concentrations (\~{}1400\&nbsp;ng\&nbsp;l-1) resulting in shellfish harvesting closures. In contrast, the 2013 spring was characterised by a P. delicatissima bloom without any toxic event. Above all, the results show that high pDA concentrations coincided with the presence of P. australis and with potential silicate limitation (Si:N\&nbsp;\&lt;\&nbsp;1), while nitrate concentrations were still replete. The contrasting environmental conditions between 2012 and 2013 highlight different environmental controls that might favour the development of either P. delicatissima or P. australis. This study points to the key role of Pseudo-nitzschia diversity and cellular toxicity in the control of particulate domoic acid variations and highlights the fact that diversity and toxicity are influenced by nutrients, especially nutrient ratios.</p>
