Phylogeny and Genetic Population Structure of Dominant Copepods in Two Ponds with Contrasting Salinities in the Solar Saltern of Sfax (Tunisia) Based on Mitochondrial (COI and Cytb) and Nuclear (18S) DNA Sequences

Diversity
Due to the complexity of taxonomic classification based on the classical morphological characters of copepods, phylogenies have been ambiguous. In this study, we investigate the phylogeny of copepods, including four species from three orders, in the ...

Bioaccumulation of methylmercury in a marine copepod

Environmental Toxicology and Chemistry, 2016
Abstract   Methylmercury (MeHg) is known to biomagnify in marine food chains, resulting in higher concentrations in upper trophic level animals than their prey. To better understand how marine copepods, an important intermediate between phytoplankton and forage fish at the bottom of the food chain ...
