Genetic Diversity, Population Structure and Differentiation of Farmed and Wild African Catfish (Clarias gariepinus) in Nigeria

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT The African catfish (Clarias gariepinus) is a commercially important species, for both fisheries and aquaculture, and is now the most commonly farmed fish in sub‐Saharan Africa. However, knowledge about the genetic diversity and population structure of natural and farmed populations, which is crucial for effective conservation and sustainable ...

First Record of Triops cancriformis (Branchiopoda: Notostraca) in Qatar: Its Origin and Range Expansion Inferred From Genetics, Morphology, and Reproduction

Ecology and Evolution, Volume 15, Issue 12, December 2025.
First record of Triops cancriformis is reported in Qatar using genetic, morphological, and reproductive data. The closest relative of this population is found in Germany. Dispersal of propagules is believed to be via avian seasonal migration. ABSTRACT The presence of Triops cancriformis has not been broadly reported outside Europe or North Africa ...

Colony and population genetic structure of the newly invasive white‐footed ant (Technomyrmex difficilis) in the United States

Insect Science, Volume 32, Issue 6, Page 1954-1968, December 2025.
Abstract The invasive white‐footed ant Technomyrmex difficilis has emerged as a rising pest in several regions, yet its invasion dynamics remain underexplored. This species outcompetes native ants and causes agricultural losses by tending pest insects, including aphids and mealybugs.

Genetic identification of ophichthid fishes through DNA barcoding

Mitochondrial DNA. Part B. Resources, 2020
Ophichthidae is the most ecologically diverse family of the order Anguilliformes; however, high morphological similarity and a long larval stage make precise identification difficult.

Advancing Marine Conservation: Metabarcoding and Metaphylogeography for a Multi‐Year Biomonitoring of Benthic Communities of National Parks Across Two Seas

Diversity and Distributions, Volume 31, Issue 11, November 2025.
ABSTRACT Aim We have applied a combined metabarcoding and metaphylogeography approach to temporal monitoring of marine protected areas. Biomonitoring is central to conservation, and new molecular methods, in particular metabarcoding‐based techniques, are changing our ability to track diversity in space and time.

Complex population genetic structure of the bark beetle predator Thanasimus formicarius (L.) (Coleoptera: Cleridae) across its European range

Agricultural and Forest Entomology, Volume 27, Issue 3, Page 437-451, August 2025.
Abstract Thanasimus formicarius (L.) (Coleoptera: Cleridae) is an important bark beetle predator and can reduce bark beetle population densities of some of the most severe forest pests in Europe. We analysed the population genetics and phylogeography of T.
