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.

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‐

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 ...

Reproductive Anatomy of Chondrichthyans: Notes on Specimen Handling and Sperm Extraction. I. Rays and Skates [PDF]

open access: yesAnimals, 2021
The superorder Batoidea (rays, skates, and relatives), constitutes one of the most threatened group of vertebrates. Strengthening ex situ conservation programs developed in research centers and public aquaria could be a way of addressing this situation ...
