First mitochondrial genomes of Capitellidae and Opheliidae (Annelida) and their phylogenetic placement

open access: yesMitochondrial DNA. Part B. Resources, 2022
The complete mitochondrial genomes of Notomastus sp. (15,776 bp) (Annelida: Capitellidae) and Armandia sp. (18,538 bp) (Annelida: Opheliidae) were assembled for the first time. A group II intron (303 bp) was found in cox1 of Notomastus sp. A phylogenetic

Is tagging with visual implant elastomer a reliable technique for marking earthworms? [PDF]

open access: yes, 2009
Visual implant elastomer (VIE) has recently been employed to investigate different aspects of earthworm ecology. However, a number of fundamental questions relating to the detection and positioning of the tag, its persistence and potential effects on ...

Adaptation and evolution of deep-sea scale worms (Annelida: Polynoidae): insights from transcriptome comparison with a shallow-water species

open access: yesScientific Reports, 2017
Polynoid scale worms (Polynoidae, Annelida) invaded deep-sea chemosynthesis-based ecosystems approximately 60 million years ago, but little is known about their genetic adaptation to the extreme deep-sea environment.

What Are the Phylogenetic Limits to Pollinator Diversity?

open access: yesJournal of Applied Entomology, Volume 149, Issue 5, Page 697-703, June 2025.
ABSTRACT Although huge progress has been made over the past 200 years in identifying the diversity of pollinators of angiosperms and other plants, new discoveries continue to be made each year, especially in tropical areas and in the fossil record. In this perspective article I address the following questions: Just how diverse are the pollinators and ...

Life in Extreme Conditions: Diet and Condition of the Extremophile Fish Aphanius almiriensis (Teleostei: Cyprinodontiformes) in a Thermal Rheocrene Spring

open access: yesEcology and Evolution, Volume 15, Issue 5, May 2025.
This study aims to answer some questions about the bioecological traits of an extremophile fish Aphanius almiriensis in order to understand how it can survive and colonize the extreme habitat conditions. To this end, some bioecological characteristics—condition, diet, and feeding strategy—of A. almiriensis inhabiting the Tuzla thermal spring, which has

DNA Extraction Methodology has a Limited Impact on Multitaxa Riverine Benthic Metabarcoding Community Profiles

open access: yesEnvironmental DNA, Volume 7, Issue 3, May/June 2025.
This work examines how DNA extraction methodology may bias the analysis of community composition using amplicon sequencing at a cross‐kingdom level in river phytobenthos samples. Our overall findings suggest that, irrespective of kit, the application of mechanical lysis is likely to improve low abundance community member detection of microbes. However,
