Desenho amostral em meiofauna marinha

open access: yesVértices, 2010
As atividades humanas litorâneas sobre a biota marinha têm levado a discussões sobre protocolos de amostragem adequados, de forma que os vários estudos possam ser comparados.

Meiofauna in Tropical Montane Streams: Biotic and Abiotic Factors Regulating Communities

open access: yesActa Biológica Colombiana, 2023
Meiofauna is a group of heterotrophic organisms smaller than macroinvertebrates but larger than microfauna and characterized by groups such as testate amoebae, ciliates, and nematodes.

Native and Invasive Crayfish Species Impact on the Development of Fire Salamander Larvae: A Pilot Field Study From Northern Italy

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT In northern Italy, the ongoing spread of non‐native red‐swamp crayfish Procambarus clarkii keeps indirectly decimating native populations of white‐clawed crayfish Austropotamobius pallipes complex and is now also threatening local amphibians adapted to slow‐flowing, hilly streams at the borders of its distribution.

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

open access: yesEnvironmental DNA
Meiofauna (all invertebrates smaller than 1 mm) are not only sensitive to environmental changes but also contribute significantly to nutrient cycling and energy transfer to higher trophic levels.

Abundance of Meiofauna and Physical-Chemical Parameters as Water Quality Indicator

open access: yesIlmu Kelautan, 2019
The zone of Losari Coast is an icon of Makassar city, however increase activity of surrounding communities causes a decrease in the water quality. Meiofauna is an effective benthic organism used as an indicator of water quality.

Warming and Sea‐Level Rise Transform Intertidal Sediment Thermal Dynamics

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Intertidal sediments are important hotspots in coastal ecology and biogeochemistry. Their function and ecology are strongly controlled by temperature, yet the impact of future climate warming and sea‐level rise (SLR) on their thermal dynamics remains unquantified.

Low Denitrification, Anammox, and Dissimilatory Nitrate Reduction to Ammonium Rates in a Low Disturbance Mangrove‐Saltmarsh System Using an in Situ Intact Chamber Method

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Mangroves and saltmarshes can remove anthropogenic nitrogen (N) moving from the land to the ocean, but many previous N cycling measurements used destructive sampling procedures that excluded important habitats such as crab burrows, pneumatophores, and saltmarsh vegetation.

The effect of estuarine system on the meiofauna and nematodes in the East Siberian Sea

open access: yesScientific Reports, 2021
Arctic meiofauna and nematodes were examined at 12 stations in the East Siberian Sea, covering a depth range of 13–59 m and an estuarine-shelf system from the Indigirka and Kolyma rivers to the adjacent shelf.

Unravelling Bulk Ichthyoplankton Diversity in Vietnam: Metabarcoding Validation With Controlled Mock Samples

open access: yesMolecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT The sustainability of Southeast Asian fisheries hinges on high‐throughput tools for monitoring early life‐stage fish biodiversity. However, applying DNA metabarcoding to hyper‐diverse tropical ichthyoplankton requires rigorous calibration to ensure quantitative reliability.

Meiofauna Community in Soft Sediments at TAG and Snake Pit Hydrothermal Vent Fields

open access: yesFrontiers in Marine Science, 2020
The risk assessment of seafloor massive sulfide (SMS) mining on meiobenthic organisms, specifically on soft-sediment meiofauna, is impeded by a lack of knowledge on the biology and ecology of these communities.
