Is DNA metabarcoding an option for formaldehyde‐preserved zooplankton time series?
Limnology and Oceanography: Methods, EarlyView.Abstract The recovery of amplifiable DNA from formaldehyde‐fixed (FF) zooplankton samples has long been considered problematic, but advances in degraded‐DNA retrieval have renewed interest in FF samples. To access the information stored in long‐term zooplankton time series, we evaluated methods for extracting amplifiable DNA from community samples ...

Revista Mexicana de Biodiversidad, 2018 The identity of the freshwater nemertean Prostoma graecense (Böhming, 1892) from Lake Xochimilco is solved 75 years after its first recording. Identification of the specimens was accomplished via both morphological and molecular means, the latter ...

Ribbon worm relationships: a phylogeny of the phylum Nemertea [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2003 We present the most extensive phylogenetic analysis to date, to our knowledge, of higher-level nemertean relationships, based on sequence data from four different genes (the nuclear genes for nuclear large subunit rRNA (28S rRNA) and histone H3 (H3), and the mitochondrial genes for mitochondrial large subunit rRNA (16S rRNA) and cytochrome c oxidase ...

Remote Sensing in Ecology and Conservation, EarlyView.Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Mitochondrial genome of Parborlasia corrugatus (Nemertea: Lineidae)
Mitochondrial DNA. Part B. Resources, 2019 We present the complete mitochondrial genome of the herteronemertean Parborlasia corrugatus. Within the 15,499 bp genome, we were able to recover 13 protein-coding genes as well as two rRNA and 22 tRNA.

Biological Diversity, Volume 3, Issue 3, Page 149-157, September 2026.Mesozooplankton assemblages differed significantly both between and within Baltic Sea bays, driven mainly by local salinity and temperature gradients. Distinct communities occurred over distances of less than 1 km, demonstrating strong fine‐scale spatial variability.

Frontiers in Zoology, 2019 Background The trochozoan excitatory peptide (EP) and its ortholog, the arthropod CCHamide, are neuropeptides that are only investigated in very few animal species. Previous studies on different trochozoan species focused on their physiological effect in

Environmental DNA, Volume 8, Issue 5, September‐October 2026.Bulk‐ and eDNA‐metabarcoding were compared across 50 groundwater sites (monitoring wells, springs, hydrants) to assess invertebrate communities. Both recovered different community structures with limited overlap (13.8% OTUs); eDNA was dominated by non‐stygobionts, and bulk samples by stygobionts.
