Recovering Historical eDNA From Museum-Preserved Filter Feeders via Non-Destructive Metabarcoding. [PDF]

Mol Ecol Resour
ABSTRACT Recent technical advances have significantly enhanced the value of museum specimens for molecular research, with metagenomic and metabarcoding approaches expanding further the utility of museum collections. However, given the finite number of specimens, there is a critical need to move past destructive DNA extraction approaches and to explore ...

Evaluating ecosystem caps on fishery yield in the context of climate stress and predation. [PDF]

Ecol Appl
Abstract 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 Biol
Abstract 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 Paleoclimatol
Abstract 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 Biol
Abstract 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,

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

Additions to the Taxonomy of the Antarctic Dark-Mouth Skate Bathyraja arctowskii (Dollo, 1904), with Descriptions of the Syntypes and Morphology of Teeth, Dermal Denticles and Thorns

Diversity, 2023
The taxonomy of the enigmatic dark-mouth skate, Bathyraja arctowskii (Dollo, 1904), from the Southern Ocean was finally resolved after more than 100 years of ambiguity in 2021.

Threatened fish species in the Northeast Atlantic are functionally rare

Global Ecology and Biogeography, Volume 32, Issue 10, Page 1827-1845, October 2023., 2023
Abstract Aim The criteria used to define the International Union for Conservation of Nature (IUCN) Red List categories are essentially based on demographic parameters at the species level, but they do not integrate species' traits or their roles in ecosystems.

A holistic and comprehensive data approach validates the distribution of the critically endangered flapper skate (Dipturus intermedius)

Journal of Fish Biology, Volume 103, Issue 3, Page 516-528, September 2023., 2023
Abstract Morphological similarities between skates of the genus Dipturus in the north‐eastern Atlantic and Mediterranean have resulted in longstanding confusion, misidentification and misreporting. Current evidence indicates that the common skate is best explained as two species, the flapper skate (Dipturus intermedius) and the common blue skate (D ...

First record of partial albinism in the critically endangered Angelshark (Squatina squatina) (Linnaeus, 1758)

Journal of Fish Biology, Volume 103, Issue 2, Page 439-442, August 2023., 2023
Abstract We report the first case of partial albinism in the Critically Endangered angelshark, Squatina squatina. The encounter with this specimen took place while SCUBA diving on the beach of Tufia, located on the east coast of the island of Gran Canaria on 2 April 2021.
