Neoichnology and sediment distribution in tidal flats of the mud‐dominated mesotidal Mira River estuary (Portugal)

Sedimentology, Volume 72, Issue 7, Page 2201-2238, December 2025.
ABSTRACT Invertebrate burrow morphologies and distributions are presented for the tidal flats of the middle and lower reaches of the tide‐influenced (mesotidal), mud‐dominated Mira River estuary (SW Portugal) as an analogue for interpreting the ichnology of palaeoestuarine successions.

Revision of Angursa (Arthrotardigrada: Styraconyxidae) with the description of a new species from Japan

European Journal of Taxonomy, 2019
We re-examined the type material of five of the seven described species of the marine tardigrade genus Angursa Pollock, 1979, namely, A. abyssalis Renaud-Mornant, 1981, A. bicuspis Pollock, 1979 (type species), A. capsula Bussau, 1992, A.

Characterizing Rocky Intertidal Biodiversity Using Environmental DNA Metabarcoding From Local to National Scales

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We assess the resolution of eDNA metabarcoding for detecting rocky intertidal taxa across three spatial scales—national, regional, and local. Distinct eDNA signals were observed at each scale, with community differences more pronounced at broader scales.

Environmental Gradients, Not Geographic Boundaries, Structure Meiofaunal Communities in Siberian Seas

Environmental DNA, Volume 7, Issue 3, May–June 2025.
This study uses sediment eDNA metabarcoding to assess the diversity and distribution of meiofauna in Siberian seas, marking the first application of this technique in the region. Our results reveal that meiofauna diversity is similar across the three studied seas; however, both meiofauna diversity and the maturity index of nematode communities are ...

Diagnosis of the Condition of Aquatic Ecosystems Using a Partial Assessment of Ecological and Trophic States: An Example of Small Lakes in Northern Poland

Limnological Review
The current state of aquatic ecosystems was assessed for lakes in two river–lake systems: Święta Struga (Święte and Ocypelek) and Kałębnica (Czarne Południowe and Kałębie).

Diversity and distribution of benthic invertebrates dwelling rivers of the Kruger National Park, South Africa

Koedoe: African Protected Area Conservation and Science, 2022
Meiobenthos (or meiofauna) are microscopic invertebrates that inhabit biofilms and interstitial spaces in rivers. They are diverse and extremely abundant, and they perform essential ecological functions by linking microbial production to higher trophic ...

A dataset of individual wet weights of benthic macroinvertebrates

Limnology and Oceanography Letters, Volume 9, Issue 6, Page 696-715, December 2024.
Abstract Biomass estimates are crucial for modeling and understanding energy flow through ecosystems. Many modeling frameworks rely on published body weights of organisms to convert density estimates to biomass. However, published body weight data are limited to few taxa in a limited number of systems. Here we present mean individual weights for common

Do separated taxa react differently to a long-term salinity increase? The meiobenthos changes in Bay Sivash, largest hypersaline lagoon worldwide

Knowledge and Management of Aquatic Ecosystems, 2019
In the world's largest hypersaline lagoon Bay Sivash, its ecosystem twice transformed from a previous state to a new one due to human intervention. Before the North Crimean Canal construction, it was hypersaline (average salinity of 140 g l−1). The canal

Faunal Composition of the Sumisu Caldera Hydrothermal Vent Field as a Key Baseline for Conservation in Light of Deep‐Sea Mining

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 11, November 2024.
ABSTRACT Hydrothermal vents are biodiversity hotspots on the deep seafloor powered by chemosynthetic primary production, inhabited by a specially adapted fauna whose composition varies between regions. Sumisu Caldera, located approximately 500 km south of Tokyo, hosts a hot vent with an unusual species composition among the Izu–Ogasawara Arc sites and ...

Organic Contaminant Mixture Significantly Changes Microbenthic Community Structure and Increases the Expression of PAH Degradation Genes

Frontiers in Environmental Science, 2020
Studying the effects of chemical contaminants on the structure and function of microbial and meiofauna communities have traditionally focused on specific effects of single contaminants on single species.
