Occurrence of 'Antrobathynella stammeri' (Jakobi, 1954) (Crustacea: Syncarida: Bathynellidae) in the hyporheic zones of two English karst rivers [PDF]

open access: yes, 2008
This paper reports the first records of Antrobathynella stammeri in the British Isles since 1985. Numerous individuals were observed in hyporheic water extracted from the River Skirfare (Yorkshire, UK), whilst, in an independent study, a single confirmed

Persistent Gaps and Errors in Reference Databases Impede Ecologically Meaningful Taxonomy Assignments in 18S rRNA Studies: A Case Study of Terrestrial and Marine Nematodes

open access: yesEnvironmental DNA, Volume 7, Issue 2, March/April 2025.
Public molecular databases (i.e., SILVA, EUKARYOME, BOLD) for most microbial metazoan phyla (nematodes, tardigrades, kinorhynchs, etc.) are sparsely populated, negatively impacting our ability to assign ecologically meaningful taxonomy to these understudied groups.

Contribution to the knowledge of the family Otoplanidae Hallez, 1892 (Rhabditophora, Proseriata) in the Mediterranean [PDF]

open access: yes, 2009
A growing awareness is rising that present perception of marine biodiversity is inadequate, and based upon unrepresentative data. The inadequacy of knowledge on taxonomy and distribution of marine organisms is particularly acute for interstitial ...

Bioaugmentation mitigates the impact of estrogen on coliform-grazing protozoa in slow sand filters [PDF]

open access: yes, 2016
Exposure to endocrine-disrupting chemicals (EDCs), such as estrogens, is a growing issue for human and animal health as they have been shown to cause reproductive and developmental abnormalities in wildlife and plants and have been linked to male ...

Community Analysis Reveals Biogeographical Patterns and Biodiversity Shortfalls in Antarctic Tardigrades

open access: yesJournal of Biogeography, Volume 52, Issue 3, Page 735-749, March 2025.
ABSTRACT Aim Tardigrades are important members of Antarctic metazoan communities with many endemic species. Major biogeographic patterns of Antarctic fauna have been identified, in particular regarding the zonation across the Gressitt line, dividing Continental and Peninsular Antarctica. Evidences suggest that Antarctic tardigrades follow this zonation

Meiofauna in Rhodolith Beds on the Continental Shelf of the Potiguar Basin (Brazil)

open access: yesMarine Ecology, Volume 46, Issue 2, March 2025.
ABSTRACT In continental shelves of tropical areas, ecological studies on meiofauna are scarce and most studies were mainly based on a single sampling event or limited spatial design. Along the Potiguar Basin continental shelf, carbonate sediments, produced by calcareous algae (rhodoliths) and corals, dominate. The ecology of rhodolith beds has been the

A supplement to a bibliography of samplers for benthic invertebrates [PDF]

open access: yes, 1983
A supplement to the earlier bibliography compiled by Elliott and Tullett 1978 (FBA Occas. Publ. No. 4) covering literature from December 1977 - December 1982 on samplers that could be used for the rapid removal of benthic intertebrates from the natural ...

Exploring copepod distribution patterns at three nested spatial scales in a spring system. Habitat partitioning and potential for hydrological bioindication [PDF]

open access: yes, 2015
In groundwater-fed springs, habitat characteristics are primarily determined by a complex combination of geomorphic features and physico-chemical parameters, while species assemblages are even more intricate.

Maerl Bed Conservation: Successes and Failures

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.
ABSTRACT Most ecoregions lack data on maerl distribution and ecological status, so this needs fundamental research for conservation. Brittany, NW France, is an exception and has extensive research on maerl species, associated biodiversity, human‐induced impacts and protection efforts.

The enigmatic mineral particle accumulations on the cuticular rings of marine desmoscolecoid nematodes structure and significance explained with clues from live observations [PDF]

open access: yes, 2010
The majority of Desmoscolecoidea are characterized by ring-shaped accumulations of mineral particles on the cuticle resulting in the impression of a peculiar body articulation.
