Pharmacokinetic study of voriconazole administered orally at 50 mg/kg in nursehound sharks (Scyliorhinus stellaris) and udulate skates (Raja undulata) [PDF]
Background Fungal diseases represent an ongoing problem for elasmobranchs kept under human care worldwide. When present, mycoses often lead to high mortality rates, compromising welfare and conservation programs in aquariums.

The Drivers of Mesozoic Neoselachian Success and Resilience [PDF]
The modern diversity of sharks, skates, and rays (Neoselachii) is the result of various diversification and extinction events during the Mesozoic (252–66 Ma).

Spatial segregation in eastern North Pacific skate assemblages. [PDF]
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]
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

Drivers of the spatial behaviour of the threatened thornback skate (Raja clavata)
Fish movements are fundamental to their ecology and survival. Understanding the causes and consequences of the spatial behaviour of fish is of high relevance as it provides critical knowledge for conservation purposes. Skate (Rajidae) populations face an
