The order Mysida Boas, 1883 is a group of small, shrimp‐like peracarid crustaceans with surprisingly high morphological and ecological diversity. In this study, a new genus and species of deep‐sea mysids, Muscamysis carolinensis gen. et sp. n. , is described based on a solitary specimen recently collected from the Caroline Ridge, Northwest Pacific. To determine the phylogenetic position of the new genus within Mysida, we recon...

Cumaceans are small peracarid crustaceans that can be remarkably diverse and important benthic organisms. Despite their ubiquitous presence in soft sediments, no well‐resolved phylogeny currently exists, which impedes ecological and evolutionary studies of the group. We present a phylogeny based on Bayesian inference of six markers (18S, 28S, 12S, 16S, CytB and COI), which recovers monophyly of the order, a deep split between...

Saccharina latissima is the most important habitat-forming kelp in sheltered areas of North-Atlantic, and there is also an increasing interest in cultivation and utilization of S. latissima . The cultivation activity may introduce a risk of “crop-to-wild” gene flow from the cultivated crops to natural populations. A baseline study to examine genetic structure and gene flow in S. latissima along the Norwegian coast was therefor...
