Epilithic Algal and Meiofaunal Assemblages of Arctic/Alpine Lakes and Streams Along Latitudinal and Environmental Gradients in Scandinavia

Freshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Epilithic biofilms along a latitudinal gradient of Arctic/alpine lakes and streams were analysed for their composition of algae (incl. cyanobacteria) and meiofaunal assemblages and correlated these with environmental variables. The composition of algal, meiofauna and nematode assemblages differed between lakes and streams.

Predicting large-scale spatial patterns of marine meiofauna: implications for environmental monitoring

Ocean and Coastal Research
This study aims model the distribution of meiofauna indicators in relation to environmental variables from the Santos Basin continental margin, SE Brazil, using machine learning techniques, to provide baseline information and foster future monitoring ...

Limited Spatial and Temporal Variability in Meiofauna and Nematode Communities at Distant but Environmentally Similar Sites in an Area of Interest for Deep-Sea Mining

Frontiers in Marine Science, 2017
To be able to adequately assess potential environmental impacts of deep-sea polymetallic nodule mining, the establishment of a proper environmental baseline, incorporating both spatial and temporal variability, is essential.

DNA Metabarcoding Reveals Tardigrades' Diversity and Dispersal Patterns in European Freshwater Rock Pools

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Freshwater rock pools are ephemeral and fragile habitats that support specialised animal taxa. While distributed worldwide, these habitats are usually neglected and overlooked. We used DNA metabarcoding and metaphylogeographic approaches to study inter and intraspecific tardigrade biodiversity to identify their biogeographic patterns to ...

Effects of the burrowing crab Chasmagnathus granulata (Dana) on meiofauna of estuarine intertidal habitats of Patos Lagoon, Southern Brazil

Brazilian Archives of Biology and Technology, 2005
This study aimed to evaluate the effects of the burrowing crab Chasmagnathus granulata on meiofauna at three intertidal habitats across a tidal exposure gradient (i.e., an emerged salt marsh, an emerged mudflat and a submerged mudflat) in an estuarine ...

Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency

Limnology and Oceanography, Volume 70, Issue S2, Page S69-S83, December 2025.
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are

Experimental seabed disturbance effects on Chatham Rise deep‐sea meiofaunal communities, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1388-1421, December 2025.
ABSTRACT Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately ...

Composition and vertical distribution of metazoan meiofauna assemblages on the continental shelf off central Chile

Latin American Journal of Aquatic Research, 2015
A quantitative study of metazoan meiofauna was carried out in Valparaiso Bay (33°S 71°W) which is affected by seasonal hypoxia in central Chile. The contents of bottom water, dissolved oxygen (BWDO), organic carbon, chloroplast pigments and composition ...

Variación temporal de las Comunidades de la Meiofauna en una Playa del Ecuador

Revista Tecnológica, 2012
La estructura de la comunidad de la meiofauna fue estudiada quincenalmente en dos zonas de muestreo: supralitoral e infralitoral, a lo largo de un año, en la playa arenosa de San Pedro de Manglaralto, Ecuador, para describir su patrón de distribución en

Sea ice meiofauna distribution on local to pan‐Arctic scales

Ecology and Evolution, 2018
Arctic sea ice provides microhabitats for biota that inhabit the liquid‐filled network of brine channels and the ice–water interface. We used meta‐analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in
