A multi‐level exploration of the relationship between temperature and species diversity: Two cases of marine phytoplankton

Ecology and Evolution, Volume 12, Issue 12, December 2022., 2022
Previous studies of T–diversity relationships suggested that the T–diversity relationships were not always positive or negative and they could be unimodal or otherwise. Thus, this study uses the piecewise model, rather than the method of the overall correlation between T and diversity, to explore the details of how exactly diversity changes with T ...

Dinoflagellate hosts determine the community structure of marine Chytridiomycota: Demonstration of their prominent interactions

Environmental Microbiology, Volume 24, Issue 12, Page 5951-5965, December 2022., 2022
Abstract The interactions of parasitic fungi with their phytoplankton hosts in the marine environment are mostly unknown. In this study, we evaluated the diversity of Chytridiomycota in phytoplankton communities dominated by dinoflagellates at several coastal locations in the NW Mediterranean Sea and demonstrated the most prominent interactions of ...

Paralytic Toxins Accumulation and Tissue Expression of α-Amylase and Lipase Genes in the Pacific Oyster Crassostrea gigas Fed with the Neurotoxic Dinoflagellate Alexandrium catenella

Marine Drugs, 2012
The pacific oyster Crassostrea gigas was experimentally exposed to the neurotoxic Alexandrium catenella and a non-producer of PSTs, Alexandrium tamarense (control algae), at concentrations corresponding to those observed during the blooming period.

White spot syndrome virus host range and impact on transmission

Reviews in Aquaculture, Volume 14, Issue 4, Page 1843-1860, September 2022., 2022
Abstract White spot syndrome virus (WSSV), the etiological agent of white spot disease (WSD), is a significant pathogen affecting shrimp farming industry worldwide. White spot syndrome virus is a generalist virus mainly infecting decapod crustaceans. The aims of this review were to: (1) Re‐evaluate and update the status of reported WSSV host and vector

Patterns of paralytic shellfish toxicity in the St. Lawrence region in relationship with the abundance and distribution of Alexandrium tamarense

Scientia Marina, 2003
Shellfish toxin data from 11 years and Alexandrium tamarense abundance during 6 of those years are analysed. Comparison of PSP toxicity in Mytilus edulis with PSP toxicity in Mya arenaria shows a significant correlation (r2=0.61), with M.

Comparing metabarcoding and morphological approaches to identify phytoplankton taxa associated with harmful algal blooms

FACETS, 2020
Molecular techniques are expected to be highly useful in detecting taxa causing harmful algal blooms (HABs). This is the first report in Canada evaluating HABs-related species identification using a combination of morphological and molecular approaches ...
