Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

open access: yesEnvironmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...

Tiltaksrettet overvåking av Årdalsfjorden i henhold til vannforskriften. Overvåking for Hydro Aluminium Årdal Karbon, Hydro Aluminium Årdal Metallverk og Norsun [PDF]

open access: yes, 2016
Alle de fem sedimentstasjonene klassifiseres til «moderat økologisk tilstand» og «ikke god kjemisk tilstand». Bunnfauna gir god tilstand, men overskridelser av EQS-verdien for flere vannregionspesifikke stoffer (hovedsakelig PAH-forbindelser) trekker ...

A Taxonomic Catalogue of Japanese Nemerteans (Phylum Nemertea) [PDF]

open access: yesZoological Science, 2007
A literature-based taxonomic catalogue of the nemertean species (Phylum Nemertea) reported from Japanese waters is provided, listing 19 families, 45 genera, and 120 species as valid. Applications of the following species names to forms previously recorded from Japanese waters are regarded as uncertain: Amphiporus cervicalis, Amphiporus depressus ...

Does the frontal sensory organ in adults of the hoplonemertean Quasitetrastemma stimpsoni originate from the larval apical organ?

open access: yesFrontiers in Zoology, 2020
Background The apical organ is the most prominent neural structure in spiralian larvae. Although it has been thoroughly investigated in larvae of the class Pilidiophora in phylum Nemertea, studies on its structure in other nemertean larvae are limited ...

Effects of beach remourishment on the benthic macrofauna and the fishes of the nearshore zone at Sebastian Inlet State Recreation Area [PDF]

open access: yes, 1987
Approximately 100,000 cubic yards of sand was transported to the ocean beach to renourish the eroded beach front during the period December 1985 through May 1986.

The aquatic annelid fauna of the San Marcos River headsprings, Hays County, Texas

open access: yesZooKeys, 2016
The San Marcos River in Central Texas has been well studied and has been demonstrated to be remarkably specious. Prior to the present study, research on free-living invertebrates in the San Marcos River only dealt with hard bodied taxa with the exception

PARTHENOGENESIS IN CARCINONEMERTES SPP. (NEMERTEA: HOPLONEMERTEA)

open access: yesThe Biological Bulletin, 1986
When juveniles of Carcinonemertes spp. are removed from male crabs and raised in the laboratory, a 50:50 sex ratio is obtained. Isolated females produce egg strings typical of Carcinonemertes, except that the embryos are haploid, with about 13 chromosomes per cell. Larvae develop at least to hatching, and some do hatch. Nearly all of the 146 females so

Status of the Nemertea as predators in marine ecosystems

open access: yesHydrobiologia, 2001
The ecology of nemertean predators in marine ecosystems is reviewed. Nemerteans occur in most marine environments although usually in low abundances. Some species, particularly in intertidal habitats, may reach locally high densities. During specific time periods appropriate for hunting, nemerteans roam about in search of prey.
