Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs. [PDF]
Environ Microbiol RepHere we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

Description of a new deep-water dogfish shark from Hawaii, with comments on the Squalus mitsukurii species complex in the West Pacific [PDF]
ZooKeys, 2018 Dogfish sharks of the genus Squalus are small, deep-water sharks with a slow rate of molecular evolution that has led to their designation as a series of species complexes, with low between-species diversity relative to other taxa.

High hydrostatic pressure effects on arginine vasotocin levels in fish
Aquatic Biology, 2020 The present study investigates the response of the hormone arginine vasotocin (AVT), the non-mammalian antidiuretic hormone, to the acclimation of fish to high hydrostatic pressure (5.1 MPa). Two fish species with different osmoregulatory strategies, the

Exploring variability in the diet of depredating sperm whales in the Gulf of Alaska through stable isotope analysis [PDF]
Royal Society Open Science, 2020 Sperm whales interact with commercially important groundfish fisheries offshore in the Gulf of Alaska (GOA). This study aims to use stable isotope analysis to better understand the trophic variability of sperm whales and their potential prey, and to use ...

Aquaporin 4 is a ubiquitously expressed isoform in the dogfish (Squalus acanthias) shark.
Frontiers in Physiology, 2012 The dogfish orthologue of aquaporin 4 (AQP4) was amplified from cDNA using degenerate PCR followed by cloning and sequencing. The complete coding region was then obtained using 5’ and 3’ RACE techniques.

The use of satellite tags to redefine movement patterns of spiny dogfish (Squalus acanthias) along the U.S. east coast: implications for fisheries management. [PDF]
PLoS ONE, 2014 Spiny dogfish (Squalus acanthias) are assumed to be a highly migratory species, making habitual north-south migrations throughout their northwestern Atlantic United States (U.S.) range.

Distribution of skates and sharks in the North Sea: 112 years of change [PDF]
, 2016 How have North Sea skate and shark assemblages changed since the early 20th century when bottom trawling became widespread, whilst their environment became increasingly impacted by fishing, climate change, habitat degradation and other anthropogenic ...
