Environmental DNA (eDNA) originates from cellular material shed by organisms into aquatic
or terrestrial environments and can be sampled and monitored using metabarcoding …

The freshwater and marine fish faunas of South America are the most diverse on Earth, with
current species richness estimates standing above 9100 species. In addition, over the last …

Abstract Background The megadiverse Neotropical freshwater ichthyofauna is the richest in
the world with approximately 6,000 recognized species. Interestingly, they are distributed …

The discovery of fluorescent proteins has revolutionized experimental biology. Whereas the
majority of fluorescent proteins have been identified from cnidarians, recently several …

Here we report a governmental initiative to enforce a regulatory program based on DNA
Barcode identification of mislabeled seafood products commercialized in Southern Brazil …

Here, we report trading of endangered shark species in a world hotspot for elasmobranch
conservation in Brazil. Data on shark fisheries are scarce in Brazil, although the northern …

Species identification based on the DNA sequence of a fragment of the cytochrome c
oxidase subunit I gene in the mitochondrial genome, DNA barcoding, is widely applied to …

Accurate identification of fishes is essential for understanding their biology and to ensure
food safety for consumers. DNA barcoding is an important tool because it can verify …

Sharks developed life history traits that make them susceptible to overfishing. This is, in turn,
a risk for extinction, and several species are affected. The high price of shark fins in the …

Morphological identification in the field can be extremely difficult considering fragmentation
of species for trade or high similarity between congeneric species. In this context, the shark …
