In fishes, as in other vertebrate species, the DNA component of the telomeres consists of the
tandemly repeated TTAGGG motif. The length of the telomeric arrays in fishes ranges from 2 …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

Abstract Purpose of Review Fishes exhibit the greatest biodiversity among extant
vertebrates. In fact, about 34,000 fish species are currently estimated, of which~ 25% are …

Telomere has a central role in chromosomal stability events. Chromosome ends organized
in telomere-loop prevent activation of DNA damage response (DDR) mechanisms, thus …

The Neotropical knifefish genus Gymnotus is the most broadly distributed and the most
diverse (34+ species) gymnotiform genus. Its wide range includes both Central and South …

Morphological conservatism among closely related species often results in incongruent
taxonomic classification between studies, leading to disagreements about the inferred …

The bluntnose knifefish genus BrachyhypopomusMago-Leccia, 1994, is diagnosed from
other Rhamphichthyoidea (Rhamphichthyidae+ Hypopomidae) by the presence of a disk …

A comparative map** of U2 small nuclear RNA (snRNA) and 5S ribosomal RNA (rRNA)
genes was performed in 6 Gymnotus species. All species analyzed presented the U2 …

The banded knife fish Gymnotus carapo is among the most widely distributed, broadly
adapted (eurytopic), and phenotypically variable fish species in South America, with a …

A complete understanding of animal signal evolution necessitates analyses of both the
proximate (eg anatomical and physiological) mechanisms of signal generation and …
