The freshwater fish genus Astyanax is one of the most diverse among the Characidae. The
genus is defined by a combination of character states that are widely distributed in …

Since their inception, DNA barcodes have become a powerful tool for understanding the
biodiversity and biology of aquatic species, with multiple applications in diverse fields such …

An accurate species delimitation is critical for biological studies. In this context, the use of
molecular techniques along with species delimitation methods would help to a rapid and …

Polypedilum Kieffer (Diptera: Chironomidae), with 520 currently known species worldwide,
can be extremely difficult to identify species level based on the morphology. We used 3,670 …

Neotropical tetras of the family Characidae form the largest and most taxonomically complex
clade within the order Characiformes. Previous phylogenetic relationships concur on the …

The COI gene is widely used as a DNA barcode in animals that can assist in the
identification of species. One of the widely used aggregators of DNA barcodes is the …

Environmental DNA (eDNA) is an effective approach for detecting vertebrates and plants,
especially in aquatic ecosystems, but prior studies have largely examined eDNA in cool …

DNA barcoding methods use a single locus (usually the mitochondrial COI gene) to assign
unidentified specimens to known species in a library based on a genetic distance threshold …

The high-throughput analysis of satellite DNA (satDNA) content, by means of Illumina
sequencing, unveiled 45 satDNA families in the genome of Astyanax paranae, with repeat …

Coexistence of ecomorphologically similar species in diverse Neotropical ecosystems has
been a focus of long-term debate among ecologists and evolutionary biologists. Such …
