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.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Scalable Benthic Biomonitoring: Trade‐Offs Between Bulk and Environmental DNA Metabarcoding Across Sediment Types

open access: yesEnvironmental DNA, Volume 8, Issue 3, May–June 2026.
Direct eDNA metabarcoding is the most scalable method for large benthic monitoring programs, provided that sampling effort is increased to compensate for slightly lower per‐sample biodiversity recovery. ABSTRACT DNA metabarcoding offers prospects to assess benthic biodiversity in a more scalable and comprehensive way, but processing methods remain ...

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.

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 Seasonal Rhythms of Coastal eDNA: Insights Into Biodiversity and Regional Detection Patterns

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Seasonal variation affects environmental DNA (eDNA) detection, yet its influence on species monitoring remains underexplored. This study examines eDNA detection windows across taxa, primers, and regions, finding that most species have short detection periods (1–2 months) that vary with taxonomy and primer choice. These results underscore the importance

Ship hull fouling in the port of Recife, Pernambuco

open access: yesBrazilian Journal of Oceanography, 2007
Ports of big coastal cities are exposed to exotic species as a consequence of shipping traffic. As the Port of Recife receives an annual average of 491 ships from other regions of Brazil and from all over the world, this work was aimed at knowing which ...

Environmental Gradients and Ecological Processes Are Main Drivers of Eukaryotic Diversity in the Eastern Red Sea

open access: yesEnvironmental DNA, Volume 8, Issue 1, January–February 2026.
Across 266 water column samples, COI eDNA metabarcoding detected 4298 eukaryotic MOTUs spanning 40 phyla in the Eastern Red Sea. Community composition varied strongly across depth and regions, revealing hidden biodiversity patterns and providing a baseline for conservation‐oriented monitoring in a future‐ocean analogue.
