Revealing Hidden Diversity of the Underestimated Neotropical Ichthyofauna: DNA Barcoding in the Recently Described Genus Megaleporinus (Characiformes: Anostomidae)

Frontiers in Genetics, 2017
Molecular studies have improved our knowledge on the neotropical ichthyofauna. DNA barcoding has successfully been used in fish species identification and in detecting cryptic diversity. Megaleporinus (Anostomidae) is a recently described freshwater fish

Species diversity of freshwater shrimp in Henan Province, China, based on morphological characters and COI mitochondrial gene

Ecology and Evolution, 2021
Freshwater shrimp are a rich species group, with a long and problematic taxonomic history attributed to their wide distribution and similar morphological characteristics.

Uncovering Hidden Diversity: Three New Species of the Keratella Genus (Rotifera, Monogononta, Brachionidae) of High Altitude Water Systems from Central Mexico

Diversity, 2021
The correct identification of species is an essential step before any study on biodiversity, ecology or genetics. Keratella is a genus with a predominantly temperate distribution and with several species being endemics or restricted geographically.

Phylogenetic analyses of the leafhopper tribe Chiasmini Distant, 1908 and delimination of species of the genus Exitianus Ball, 1929 (Hemiptera: Cicadellidae: Deltocephalinae: Chiasmini) in China based on molecular data

European Journal of Taxonomy
Previous phylogenetic analyses of the grass-specialist leafhopper tribe Chiasmini have resolved relationships among genera but have included few representatives of individual genera.

Efficiency of the cytochrome c oxidase subunit II gene for the delimitation of termite species (Blattodea: Isoptera) in the state of Paraíba, northeastern Brazil. [PDF]

PLoS One
With the aim of expanding the possibilities of identifying termite species, in the present study we generated genetic data based on sequences of the mitochondrial gene encoding cytochrome c oxidase subunit II (COII) for termites (Blattodea: Isoptera ...

How many cows are in the desert? Molecular phylogeny and species delimitation of the genus Gyriosomus (Coleoptera: Tenebrionidae: Pimeliinae) from the Atacama Desert

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
The newly systematic rearrangement of Gyriosomus recognizes 9 clades, validates 21 taxonomical species and suggests 12 synonyms and 12 species candidates. Three taxonomical species were not evaluated. Polymorphisms, convergences and crypsis have been detected, and therefore morphology‐based taxonomy should be approached with caution. Ecological drivers

Species delimitation of neotropical Characins (Stevardiinae): Implications for taxonomy of complex groups.

PLoS ONE, 2019
Accurate species delimitation is crucial for studies of phylogeny, phylogeography, ecology, conservation and biogeography. The limits of species and genera in the Characidae family are controversial due to its uncertain phylogenetic relationships, high ...

Complex evolution and biogeographic history of moss‐inhabiting flea beetles from the Taiwan‐Ryukyu Island Arc (Coleoptera: Chrysomelidae: Alticini)

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
Extensive radiation of moss‐inhabiting flea beetles in Taiwan and Japan: The Ivalia uenoi complex displays high species diversity closely related to Japanese species. Complex biogeography revealed by phylogenomics: ddRAD data uncovered a history shaped by Miocene vicariance and Pliocene dispersal from Taiwan across the Taiwan‐Ryukyu archipelago ...

Spatial distribution and drivers of aboveground forest biomass in Mexico using GEDI and national forest inventory data

Remote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 755-772, December 2025.
GEDI LiDAR‐derived biomass models were calibrated using local field data across various forest types in Mexico, resulting in a significant improvement in AGBD estimation accuracy compared to the standard GEDI products. The models reduced biomass estimation errors by over 30% and showed the highest accuracy in areas with moderate slopes and low forest ...
