Intra- and inter-spatial variability of meiofauna in hadal trenches is linked to microbial activity and food availability [PDF]

Scientific Reports, 2022
Hadal trenches are depocenters for organic material, and host intensified benthic microbial activity. The enhanced deposition is presumed to be reflected in elevated meiofaunal standing-stock, but available studies are ambiguous. Here, we investigate the

Potential impacts of polymetallic nodule removal on deep-sea meiofauna [PDF]

Scientific Reports, 2021
Deep seabed mining is potentially imminent in the Clarion Clipperton Fracture Zone (CCFZ; northeast Pacific). Seabed collectors will remove polymetallic nodules and the surrounding surface sediments, both inhabited by meiofauna, along their path.

Meiofauna promotes litter decomposition in stream ecosystems depending on leaf species

Ecology and Evolution, 2020
Litter decomposition, a fundamental process of nutrient cycling and energy flow in freshwater ecosystems, is driven by a diverse array of decomposers. As an important component of the heterotrophic food web, meiofauna can provide a trophic link between ...

Meiofauna in a Potential Deep-Sea Mining Area—Influence of Temporal and Spatial Variability on Small-Scale Abundance Models

Diversity, 2020
In large areas of the Clarion Clipperton Fracture Zone (northeast Pacific), exploration of deep-sea polymetallic nodules as a potential source of high-technology metals is ongoing. Deep-sea mining may have a severe impact on the benthic communities. Here,

Metacommunity Theory and Metabarcoding Reveal the Environmental, Spatial and Biotic Drivers of Meiofaunal Communities in Sandy Beaches. [PDF]

Mol Ecol
ABSTRACT Understanding the processes that shape community assembly is a critical focus of ecology. Marine benthic meiofauna, microscopic invertebrates inhabiting sediment environments, play important roles in ecosystem functioning but have been largely overlooked in metacommunity studies due to the lack of community data. In this study, we quantify the

Spatial and Temporal Variation in Deep-Sea Meiofauna at the LTER Observatory HAUSGARTEN in the Fram Strait (Arctic Ocean)

Diversity, 2020
Time-series studies at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN have yielded the world’s longest time-series on deep-sea meiofauna and thus provide a decent basis to investigate the variability in deep-sea meiobenthic communities ...

Short-term microplastic effects on marine meiofauna abundance, diversity and community composition [PDF]

PeerJ
Background Due to the copious disposal of plastics, marine ecosystems receive a large part of this waste. Microplastics (MPs) are solid particles smaller than 5 millimeters in size. Among the plastic polymers, polystyrene (PS) is one of the most commonly

Functional trait analysis reveals the hidden stability of multitrophic communities. [PDF]

Ecology
Abstract Although important for understanding how ecosystems will fare with increasing global change, the relationship between diversity and stability in multitrophic communities is still debated. Our best understanding comes from work within competitive guilds, where the relationship between stability and functional diversity is generally positive and

Distribution Patterns of Meiofauna Assemblages and Their Relationship With Environmental Factors of Deep Sea Adjacent to the Yap Trench, Western Pacific Ocean

Frontiers in Marine Science, 2019
Sediment samples were collected from 23 sites near the Yap Trench in the Western Pacific Ocean with a depth range of 2896–7837 m. The assemblage composition, spatial distribution, and relationship with environmental variables of meiofauna were studied. A
