An individual-based model for evolutionary effects of selective fishing applied to Pseudoplatystoma corruscans

open access: yesPhysica A: Statistical Mechanics and its Applications, 2012
AbstractThis paper proposes an individual-based model that takes into account the evolutionary effects of selective fishing on exploited populations. The model is an adaptation of the Penna model based on the biology of exploited species and characteristics of fishing. Given the importance of the Pintado Pseudoplatystoma corruscans, a native species of

Fatty acid profiles of five farmed Brazilian freshwater fish species from different families. [PDF]

open access: yesPLoS ONE, 2017
The proximate composition and fatty acid (FA) profiles of five Brazilian freshwater fish species, namely Brycon cephalus (BC), Cichla ocellaris (CO), Prochilodus lineatus (PL), Leporinus friderici (LF) and Pseudoplatystoma corruscans (PCO), were ...

Hybridization, Maternal Inheritance, and Evolutionary Time of Divergence of Endangered Species of <i>Hypancistrus</i> (Siluriformes: Loricariidae) in the Xingu River. [PDF]

open access: yesEcol Evol
We uncover recent hybridization dynamics among three endemic Hypancistrus species from the Xingu River, including the critically endangered H. zebra. Mitogenomic analyses reveal unidirectional maternal inheritance and recent evolutionary radiation (< 0.5 Ma), explaining their retained reproductive compatibility.

DNA metabarcoding assessment of Neotropical ichthyoplankton communities is marker-dependent. [PDF]

open access: yesEcol Evol, 2023
DNA metabarcoding has been applied as a rapid, cost‐effective, and accurate taxonomy tool, allowing the identification of multiple individuals simultaneously. The combined use of the three markers increased the genera detection rates by 25%–87.5%, allowing an increased taxonomic coverage and robust taxonomic identification of complex Neotropical ...

Assessing the population structure of Plagioscion squamosissimus (Teleostei, Perciformes, Sciaenidae) from the São Francisco River, Bahia, Brazil, using body morphology and otolith shape signatures. [PDF]

open access: yesJ Fish Biol
Abstract The south American silver croaker, Plagioscion squamosissimus, holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per ...

Multiple genetic lineages of anadromous migratory Mekong catfish Pangasius krempfi revealed by mtDNA control region and cytochrome b. [PDF]

open access: yesEcol Evol, 2023
We used the control region and cytochrome b to quantify the genetic diversity and to elucidate historical origins and migratory patterns of Pangasius krempfi. Fish were sampled along the Mekong tributaries and coastal areas in the Mekong Delta (Vietnam) and referenced to samples in Pakse (Laos). The results indicate moderate levels of genetic diversity,

Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data. [PDF]

open access: yesCladistics
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.
