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

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