The nervous systems of basally branching nemertea (palaeonemertea). [PDF]

open access: yesPLoS ONE, 2013
In recent years, a lot of studies have been published dealing with the anatomy of the nervous system in different spiralian species. The only nemertean species investigated in this context probably shows derived characters and thus the conditions found ...

The accordion worm: a new genus and species of heteronemertean (Nemertea, Pilidiophora) from Galicia (Spain) [PDF]

open access: yesRoyal Society Open Science
Ribbon worms (Nemertea) are a less-known group of invertebrates, specially challenging for taxonomic studies due to the scarcity of external morphological features.

Identification of Six Novel Proteins Containing a ZP Module from Nemertean Species [PDF]

open access: yesBiomolecules
During fertilization, a series of reactions between the eggs and spermatozoa proceed predominantly in a species-specific manner. The molecules mediating these species-specific reactions remain unknown except in a few organisms.

Mitochondrial genome of Parborlasia corrugatus (Nemertea: Lineidae) [PDF]

open access: yesMitochondrial 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.

Comparative description of ten transcriptomes of newly sequenced invertebrates and efficiency estimation of genomic sampling in non-model taxa [PDF]

open access: yesFrontiers in Zoology, 2012
Introduction Traditionally, genomic or transcriptomic data have been restricted to a few model or emerging model organisms, and to a handful of species of medical and/or environmental importance.

Nemertide Alpha-1 as a Biopesticide: Aphid Deterrence, Antimicrobial Activity, and Safety Aspects [PDF]

open access: yesMarine Drugs
Aphid control often relies on synthetic pesticides, but their overuse has raised concerns about resistance development and negative impact on wildlife and human health. Consequently, the search for new biopesticide agents has gained significant attention.

A Field-Friendly, Non-Toxic Fixative for Integrated Morphological and Molecular Research in Non-Model Invertebrates. [PDF]

open access: yesEcol Evol
Formalin, ethanol, and RNAlater are commonly used fixatives for morphological and molecular studies, but each has limitations when specimen availability is low, as is often the case with field‐collected non‐model organisms. Here, we evaluate KINFix, a non‐toxic alcohol‐based fixative, in four invertebrate taxa and show that it effectively preserves ...

Tetrodotoxins Secretion and Voltage-Gated Sodium Channel Adaptation in the Ribbon Worm Kulikovia alborostrata (Takakura, 1898) (Nemertea)

open access: yesToxins, 2021
Nemertea is a phylum of marine worms whose members bear various toxins, including tetrodotoxin (TTX) and its analogues. Despite the more than 30 years of studying TTXs in nemerteans, many questions regarding their functions and the mechanisms ensuring ...

Development of the Nervous System of Carinina ochracea (Palaeonemer-tea, Nemertea). [PDF]

open access: yesPLoS ONE, 2016
The various clades of Lophotrochozoa possess highly disparate adult morphologies. Most of them, including Nemertea (ribbon worms), are postulated to develop via a pelagic larva of the trochophora type, which is regarded as plesiomorphic in Lophotrochozoa.
