Use of mucus as a non-invasive sampling method for DNA barcoding of stingrays and skates (batoid elasmobranchs)
(2019-03-01)
In this study we tested the use of mucus from five species of Neotropical marine batoid elasmobranchs to extract genomic DNA for barcoding and phylogenetic analysis. The DNA from all individuals sampled was successfully ...
Coastal sharks and rays in a marine protected area in southern Brazil
(2021-01-01)
In southern Brazil, we investigated shark and ray capture records in an integral protection marine protection area (MPA) that allows fishing in that area. We found 10 shark and nine ray species, of which 88.5% and 66.2%, ...

A safe haven for potential reproductive aggregations of the critically endangered Brazilian guitarfish (Pseudobatos horkelii)
(2021-01-01)
Brazilian endemic batoid elasmobranch populations have declined dramatically in the past 40 years due to anthropic activities (e.g., overfishing). The Brazilian guitarfish, Pseudobatos horkelii, included in the IUCN red ...
New record of the critically endangered striped smooth-hound, mustelus fasciatus (Garman, 1913) (chondrichthyes, triakidae), in the southwest Atlantic
(Pensoft Publishers, 2018-12-21)
We report the southernmost known occurrence in the Atlantic Ocean of the striped smooth-hound, Mustelus fasciatus (Garman, 1913). The shark, a female measuring 106 cm TL, was fished in warm coastal waters, with a salinity ...
Movement and activity patterns of the nurse shark, Ginglymostoma cirratum, in an oceanic Marine Protected Area of the South-western Atlantic
(2016-08-19)
The movement and activity patterns of the nurse shark, Ginglymostoma cirratum, a vulnerable species off Brazil, were investigated using mark-recapture and acoustic telemetry at an oceanic insular Marine Protected Area, the ...
Putative extinction of two sawfish in Mexico and the United States
(Neotropical Ichthyology, 2009-01-01)
All species of sawfish are listed by the International Union for the Conservation of Nature (IUCN) as endangered or critically endangered. In fact, the smalltooth sawfish Pristis pectinata, and the largetooth sawfish Pristis ...
Restricted connectivity and population genetic fragility in a globally endangered Hammerhead Shark
(2020-09-01)
Vagile, large-bodied marine organisms frequently have wide range dispersion but also dependence on coastal habitats for part of their life history. These characteristics may induce complex population genetic structure ...
