Enhancing metabarcoding efficiency and ecological insights through integrated taxonomy and DNA reference barcoding: A case study on beach meiofauna

open access: yesMolecular Ecology Resources, Volume 24, Issue 7, October 2024.
Abstract Molecular techniques like metabarcoding, while promising for exploring diversity of communities, are often impeded by the lack of reference DNA sequences available for taxonomic annotation. Our study explores the benefits of combining targeted DNA barcoding and morphological taxonomy to improve metabarcoding efficiency, using beach meiofauna ...

Use of eDNA and conventional sampling methods to survey rock pool (gnamma) biodiversity on granite inselbergs

open access: yesAustral Ecology, Volume 49, Issue 8, August 2024.
Environmental DNA sampling coupled with high‐throughput sequencing is increasingly recognized as a useful method for assessing biodiversity with potential applications in terrestrial environments. Rock pools on granite inselbergs support diverse aquatic communities, yet the application of eDNA to document their biodiversity is lacking.

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes [PDF]

open access: yes, 2007
Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon ...

Sulphated glycosaminoglycans support an assortment of planarian rhabdite structures [PDF]

open access: yes, 2017
Planaria are soft-bodied, bilateral flatworms of the phylum Platyhelminthes. They are covered in cilia and use ciliary-gliding to traverse the substratum while hunting.

The mitochondrial genomes of the acoelomorph worms Paratomella rubra, Isodiametra pulchra and Archaphanostoma ylvae [PDF]

open access: yes, 2017
Acoels are small, ubiquitous - but understudied - marine worms with a very simple body plan. Their internal phylogeny is still not fully resolved, and the position of their proposed phylum Xenacoelomorpha remains debated.

Adhesive organ regeneration in Macrostomum lignano [PDF]

open access: yes, 2016
BackgroundFlatworms possess pluripotent stem cells that can give rise to all cell types, which allows them to restore lost body parts after injury or amputation. This makes flatworms excellent model systems for studying regeneration.
