Spatial segregation in eastern North Pacific skate assemblages. [PDF]
PLoS ONE, 2014 Skates (Rajiformes: Rajoidei) are common mesopredators in marine benthic communities. The spatial associations of individual species and the structure of assemblages are of considerable importance for effective monitoring and management of exploited ...

Biogeographic patterns in the cartilaginous fauna (Pisces: Elasmobranchii and Holocephali) in the southeast Pacific Ocean. [PDF]
PeerJ, 2014 The abundance and species richness of the cartilaginous fish community of the continental shelf and slope off central Chile is described, based on fishery-independent trawl tows made in 2006 and 2007. A total of 194,705 specimens comprising 20 species (9

Development and evolution of dentition pattern and tooth order in the skates and rays (batoidea; chondrichthyes). [PDF]
PLoS One, 2015 Shark and ray (elasmobranch) dentitions are well known for their multiple generations of teeth, with isolated teeth being common in the fossil record.

Evaluating ecosystem caps on fishery yield in the context of climate stress and predation. [PDF]
Ecol ApplAbstract Ecosystem‐based fisheries management strives to account for species interactions and ecosystem processes in natural resource management and conservation. In this context, ecosystem‐wide caps on total fishery catches have been proposed as one tool to manage multispecies fisheries with an ecosystem approach.

Morphology of the unique egg cases of hornsharks (Heterodontiformes: Heterodontidae). [PDF]
J Fish BiolAbstract Many of the egg cases of oviparous chondrichthyans remain unknown and undescribed in the literature. Egg cases can be a useful taxonomic character for species distinction and can be a valuable indicator of a species distribution in the field.

Eocene Shark Teeth From Peninsular Antarctica: Windows to Habitat Use and Paleoceanography. [PDF]
Paleoceanogr PaleoclimatolAbstract Eocene climate cooling, driven by the falling pCO2 and tectonic changes in the Southern Ocean, impacted marine ecosystems. Sharks in high‐latitude oceans, sensitive to these changes, offer insights into both environmental shifts and biological responses, yet few paleoecological studies exist.

Diet and trophic structure of fishes in the Barents Sea: between empty and full stomachs - large individual variability follows a common pattern. [PDF]
J Fish BiolAbstract More than 27,000 stomachs from 70 species of fish were collected from the Barents Sea in 2015. Quantitative stomach content expressed relative to the body weight of the predator fish (g g−1 as %) varied by four to five orders of magnitude for six species with the largest sample size (Atlantic cod Gadus morhua, haddock Melanogrammus aeglefinus,
