Ribbon worm relationships: a phylogeny of the phylum Nemertea [PDF]

open access: yesProceedings 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 ...

Mitochondrial genome of Parborlasia corrugatus (Nemertea: Lineidae)

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.

Rediscovery of the nemertean Prostoma graecense from Xochimilco, 75 years after its first and only record

open access: yesRevista 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 ...

Translocating Intact Assemblages to Degraded Sites to Accelerate Ecological Recovery

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Estuarine ecosystems are threatened by anthropogenic pressures such as climate change, coastal development, and increased nutrient and sediment inputs. These pressures are deteriorating ecological health and threatening the functioning and services that estuarine ecosystems provide.

Ecology and Reproduction of Bunodeopsis in Tropical Northwestern Atlantic Seagrass Ecosystems

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT The seagrass ecosystems of the Tropical Northwestern Atlantic (TNA) host three described species of sea anemones in the genus Bunodeopsis Andres, 1881 (Enthemonae: Metridioidea: Acuticulata): B. antilliensis, B. globulifera, and B. pelagica.

A nemertean excitatory peptide/CCHamide regulates ciliary swimming in the larvae of Lineus longissimus

open access: yesFrontiers 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

First record of Baseodiscus mexicanus (Bürger, 1893) (Nemertea: Heteronemertea) from Japanese waters [PDF]

open access: yesCheck List, 2012
The heteronemertean Baseodiscus mexicanus (Bürger, 1893) was previously known exclusively from the eastern Pacific, except for fragmentary records from Palau and Indonesia, which suggested a possible amphi-Pacific tropical distribution. A single specimen

On the phylogenetic position of Myzostomida: can 77 genes get it wrong? [PDF]

open access: yes, 2009
Background Phylogenomic analyses recently became popular to address questions about deep metazoan phylogeny. Ribosomal proteins (RP) dominate many of these analyses or are, in some cases, the only genes included.

Hard Rock Buffet: Chemosynthetic Carbon Use and Environmental Trophic Structuring of Carbonate‐Associated Macrofauna at Southern California Methane Seeps

open access: yesMarine Ecology, Volume 47, Issue 2, March/April 2026.
ABSTRACT Diverse invertebrate communities inhabiting carbonate rocks at methane seeps may rely on a mix of local chemosynthetic production and sinking photosynthetic organic matter, with relative importance shaped by environmental conditions. We investigate the contribution of chemosynthetic carbon to macrofaunal diets at six Southern California ...

The Geonemertes problem (Nemertea) [PDF]

open access: yesJournal of Zoology, 1981
A new genus of monostiliferous hoplonemerteans, Pantinonemertes gen. nov., provides evidence for the separate evolution of terrestrial nemerteans. The genus is established for two new species found in Australia, P. enalios sp. nov., an intertidal form, and P. winsori sp.
