New insights into the genetic variability of Fasciola hepatica (Trematoda) in Algeria and relationships with other geographic regions revealed by mitochondrial DNA

open access: yesHelminthologia, 2022
This study aims to investigate the level of genetic variability of Fasciola hepatica flukes isolated from cattle in Algeria and to determine the phylogenetic and phylogeographic relationships with sequences isolated worldwide. Mitochondrial (Cytochrome c

DNA barcoding uncovers two putative new species in Trachelyopterus (Siluriformes: Auchenipteridae)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Trachelyopterus is a cryptic genus within the Neotropical catfish family Auchenipteridae with a complex history of taxonomic revisions. Despite the notable morphological and genetic similarities among its species, some studies suggest that the genus harbours greater diversity than is currently recognized, including additional species yet to be

Integrative taxonomy of Harveylithon (Corallinales, Rhodophyta) reveals three new species from Korea and expanded diversity in the northwestern Pacific

open access: yesJournal of Phycology, EarlyView.
Abstract Non‐geniculate coralline genus Harveylithon includes 12 species worldwide. In this study, we propose three new species, Ha. koreanum sp. nov., Ha. longiforme sp. nov., and Ha. planiforme sp. nov., based on integrative molecular and morphological analyses.

Molecular phylogeny of the genus Lythria and description of the male genitalia of L. venustata (Lepidoptera: Geometridae: Sterrhinae)

open access: yesEuropean Journal of Entomology, 2009
We present a molecular phylogeny incorporating all five species of the Palaearctic geometrid genus Lythria, based on a 2810-bp combined data matrix comprising the full sequence of the mitochondrial gene cytochrome oxidase subunit one (COI) and fragments ...

The genus Arthrocardia (Corallinales, Rhodophyta) in New Zealand: Description of three new species

open access: yesPhycological Research, EarlyView.
SUMMARY Three new species of the coralline algal genus Arthrocardia (Corallinophycidae, Rhodophyta) are described from New Zealand: A. meridionalis, A. perplexa, and A. robusta. These species are difficult to distinguish based on morphoanatomical characters alone and require molecular sequence data for reliable identification.

Mitochondrial COI and cytb Characterisation of K‐Lineage Varroa destructor Isolates From Kastamonu, Türkiye

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
This study provides the molecular characterisation and phylogenetic analysis of Varroa destructor collected in Kastamonu, Türkiye. Using mitochondrial COI and cytb markers, the research identifies an identical K‐lineage, offering critical insights into the genetic diversity and evolutionary relationships within the region's mite populations.

Feeding Ecology of Gould's Arrow Squid Nototodarus gouldi (Cephalopoda: Ommastrephidae) in Aotearoa New Zealand Waters

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Squids are important components of marine ecosystems because of their role as both predator and prey. Across the Tasman Sea, Gould's arrow squid (Nototodarus gouldi) is a commercially targeted ommastrephid squid that supports an economically important fishery.
