Evolution of realized Eltonian niches across Rajidae species [PDF]

open access: yesEcosphere, 2021
The notion that closely related species resemble each other in ecological niche space (i.e., phylogenetic dependence) has been a long‐standing, contentious paradigm in evolutionary biology, the incidence of which is important for predicting the ecosystem‐

Complete mitochondrial DNA sequence of Norwegian skates (Raja brachyuran Lafont, 1871) imported to Korea [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2021
In this study, the complete mitochondrial genome of Norwegian skates imported to Korea was sequenced with a circular molecule of 17,121 bp, which consisted of 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNA genes, and a control region ...

The complete mitochondrial genome of the endemic Iberian pygmy skate Neoraja iberica Stehmann, Séret, Costa, & Baro 2008 (Elasmobranchii, Rajidae) [PDF]

open access: yesMitochondrial DNA. Part B. Resources, 2021
Skates, Chondrichthyes fishes from order Rajiformes, are the most species-rich group of all Batoidea. However, their phylogenetic relationships and systematics is still a highly discussed and controversial subject.

Conservation and exploitation status of skate species (Batoidea: Rajidae) in the Balearic Islands, western Mediterranean. [PDF]

open access: yesPLoS ONE
Batoids play key roles in marine ecosystems, yet their slow life history traits make them particularly vulnerable to overexploitation. The Balearic Islands remain a hotspot of batoid diversity, although multiple species could face conservation concerns ...

The genome sequence of the blonde ray, Raja brachyura Lafont, 1871 [version 1; peer review: 2 approved] [PDF]

open access: yesWellcome Open Research
We present a genome assembly from an individual female Raja brachyura (Blonde Ray; Chordata; Chondrichthyes; Rajiformes; Rajidae). The genome sequence spans 2,700.50 megabases.

A parasite through time: Revisiting Trypanosoma rajae Laveran and Mesnil, 1902 with new molecular and morphological insights from the blood of Rajidae in the western Mediterranean [PDF]

open access: yesInternational Journal for Parasitology: Parasites and Wildlife
Trypanosomes are blood parasitic protozoa infecting Chordates, including the elasmobranch skates (Rajidae). Amongst, Trypanosoma rajae Laveran and Mesnil, 1902 is a century old parasite, first briefly described from the Mediterranean starry ray Raja ...

Behavioural Responses of a Large, Benthic Elasmobranch to Catch-and-Release Angling

open access: yesFrontiers in Marine Science, 2022
Catch-and-release angling is widespread, but the impacts of this practice for captured individuals are understudied, especially among elasmobranchs.

Bacterial community dynamics during embryonic development of the little skate (Leucoraja erinacea)

open access: yesAnimal 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.
