Abstract Large pelagic vertebrates pose special conservation challenges because their movements generally exceed the boundaries of any single jurisdiction. To assess population structure whale sharks ( Rhincodon typus ), we sequenced complete mitochondrial DNA control regions from individuals collected across a global distribution. We observed 51 site polymorphisms and 8 with indels comprising 44 haplotypes in 70 individuals, high haplotype h = 0.974 ± 0.008) nucleotide diversity (π 0.011...
Barotrauma as a result of rapid decompression has been recorded the most common injury among fish captured in tailrace hydropower dams Brazil, with catfishes representing majority them. Nevertheless, studies investigating barotrauma on catfish are scarce, determining dose–response curves and thresholds pressure changes for nektonic species, such salmonids. Experiments conducted Pimelodus pictus showed that current hypo-hyperbaric chambers used to study species can have limitations when...
Abstract The Atlantic nurse shark, Ginglymostoma cirratum , was recently listed as Vulnerable by IUCN Red List, however, highlighted, little is known about its populations in the Southwestern Atlantic. Therefore, population studies are essential to propose status evaluations and new conservation measures. Natural marks present on animals' bodies used an alternative non‐invasive method rather than usual tagging system for individual identification, thus avoiding need animal handling. This...
Multiple paternity (MP) is a phenomenon observed for more than 30 elasmobranch species. The Batoidea specious the Selachii, but only three studies of MP have been conducted on batoids. occurrence in freshwater stingrays was tested using microsatellite markers, which were developed Potamotrygon leopoldi. Six mothers and their litters genotyped, providing first evidence Potamotrygonidae, with an frequency 33%.
Barotrauma is a major cause of injury and mortality fish as they pass through hydropower turbines. Current understanding related barotrauma biased towards northern temperate southern subtropical species with single chambered swim bladders, specifically North American Australian species, respectively. Today, unprecedented development taking place in Neotropical regions where many have complex multi-chambered bladder architecture. This study investigated two dual-chambered physostomous (pacu,...
A general analysis approach for strip metallization structures enclosed in rectangular or square waveguide is presented. The technique involves the novel application of a commercially available 2.5-dimensional (2.5-D) method-of-moments-based (MoM) electromagnetic (EM) tool to three-dimensional (3-D) problem. Very good agreement demonstrated between computed and measured results several printed linear polarizers embedded within environment. This paper, authors' knowledge, represents first...
A Short-finned Pilot Whale, Globicephala macrorhynchus, was found dead and with shark bites along its body on a beach in northeast Brazil. The present study aimed to identify the species responsible for as well estimate its/their total length. Species identification performed using bite marks, which were of same diameter, suggesting they infected by one or more Tiger sharks similar size. characteristics shape distribution marks left teeth pointed Shark, Galeocerdo cuvier. length Shark...
