Morphological variation in a conservative structure: The Scapulocoracoids in Sympterygia acuta Garman, 1837 and Sympterygia bonapartii Müller & Henle, 1841 (Chondrichthyes: Rajidae)

Zootaxa, 2017
Scapulocoracoid variation in Sympterygia acuta and S. bonapartii was analyzed inter- and intraspecifically, and the utility of this structure as a diagnostic character in skates was evaluated. Skeletal pieces were obtained from a total of 85 specimens collected in coastal waters of northern Argentina in 2011 and 2012.

Evaluating the usefulness of natural tags for host population structure in chondrichthyans: Parasite assemblages of Sympterygia bonapartii (Rajiformes: Arhynchobatidae) in the Southwestern Atlantic

Fisheries Research, 2017
Abstract The usefulness of parasite tags for population discrimination of elasmobranch hosts remains largely unexplored. In order to assess the existence of different populations of Sympterygia bonapartii in the Southwestern Atlantic using its parasites as biological tags and to evaluate their usefulness as indicators for chondrichthyan hosts, we ...

A new species of Heteronybelinia (Cestoda: Trypanorhyncha) from Sympterygia bonapartii (Rajidae), Nemadactylus bergi (Cheilodactylidae) and Raneya brasiliensis (Ophidiidae) in the south-western Atlantic, with comments on host specificity of the genus

Journal of Helminthology, 2012
AbstractAdults and plerocercoids of a new species of Heteronybelinia (Trypanorhyncha, Tentaculariidae) were recovered from the skate Sympterygia bonapartii (Rajiformes: Rajidae) and two species of teleosts, Raneya brasiliensis (Ophidiiformes: Ophidiidae) and Nemadactylus bergi (Perciformes: Cheilodactylidae), respectively. Heteronybelinia mattisi n. sp.

Demographic analyses reveal differential biological vulnerability in four Southwestern Atlantic skates

Canadian Journal of Fisheries and Aquatic Sciences, 2023
More than thirty-three skate species have been registered in the Southwestern Atlantic Ocean south of 34°S (SAO), where hotspots of the endemic threatened marine chondrichthyans with high scientific and conservation priorities have been detected.
