Growth and mechanical correlations of calcified cartilage in Batoidea: A histomorphological study using the Raja asterias model. [PDF]
J Fish BiolAbstract This study investigates the growth and calcification of the appendicular skeleton in Raja asterias (Delaroche, 1809), a member of the Batoidea, to explore the relationship between histomorphology and the mechanics of batoid locomotion within the water column. Although much prior research has focused on the “tessellated pattern” in these fishes,

Distribution and taxonomic identity of the species of Narcine (Toperdiniformes: Narcinidae) in the southwestern Atlantic Ocean. [PDF]
J Fish BiolAbstract The genus Narcine is the most diverse among electric rays of the order Torpediniformes and is also the only electric ray genus with more than one species occurring in South American waters: Narcine brasiliensis and Narcine bancroftii. The first species has been historically described as distributed from Brazil's southeast coast down to ...

Aquatic eDNA outperforms sedimentary eDNA for the detection of estuarine fish communities in subtropical coastal vegetated ecosystems. [PDF]
J Fish BiolAbstract In South Africa, mangrove forests and seagrass meadows often co‐occur in estuarine systems and in combination host rich, often endemic biodiversity. There is an urgent need to explore community diversity in coastal vegetated ecosystems, given the degrading effects of climate change and anthropogenic pressures.

Individual Variation in Philopatry Is Unrelated to Activity and Space Use in the Undulate Skate <i>Raja undulata</i>. [PDF]
Ecol EvolConsistent individual variation in fine‐scale movement traits is unrelated to movements occurring at larger spatio‐temporal scales in undulate skates (Raja undulata). ABSTRACT Individual variation in behavior is widespread in animals. Movement traits, which describe how individuals interact with their environment, can vary across a range of spatial and

Behavioural Responses of a Large, Benthic Elasmobranch to Catch-and-Release Angling
Frontiers in Marine Science, 2022 Catch-and-release angling is widespread, but the impacts of this practice for captured individuals are understudied, especially among elasmobranchs.

Using citizen science photographs to identify reproductive events in an oviparous elasmobranch. [PDF]
J Fish BiolAbstract Identifying critical habitats is important for the effective management of vulnerable species. Critical habitats, such as mating or nursery grounds, support populations during key life stages and help to maximise reproductive output and population growth. In elasmobranchs, mating often happens over a defined season, suggesting sites associated

Bacterial community dynamics during embryonic development of the little skate (Leucoraja erinacea)
Animal Microbiome, 2021 Background Microbial transmission from parent to offspring is hypothesized to be widespread in vertebrates. However, evidence for this is limited as many evolutionarily important clades remain unexamined.
