“…The effects of shallow-water mining wastes (heavy metals) on meiofauna were investigated in the Fal Estuary system (southwest England), revealing that some nematode species may have developed different tolerance mechanisms to survive in areas with high heavy metal concentrations (Somerfield et al 1994). Microcosm and mesocosm scale experiments on meiofauna recolonisation in discharges tailing sediments were performed in Benete Bay (Indonesia; Gwyther et al 2009). This study revealed that meiofauna colonised tailing sediments after 40 days and recovered control values after 97 days.…”

Our planet is changing, and one of the most pressing challenges facing the scientific community revolves around understanding how ecological communities respond to global changes. From coastal to deep-sea ecosystems, ecologists are exploring new areas of research to find model organisms that help predict the future of life on our planet. Among the different categories of organisms, meiofauna offer several advantages for the study of marine benthic ecosystems. This paper reviews the advances in the study of meiofauna with regard to climate change and anthropogenic impacts. Four taxonomic groups are valuable for predicting global changes: foraminifers (especially calcareous forms), nematodes, copepods and ostracods. Environmental variables are fundamental in the interpretation of meiofaunal patterns and multistressor experiments are more informative than single stressor ones, revealing complex ecological and biological interactions. Global change has a general negative effect on meiofauna, with important consequences on benthic food webs. However, some meiofaunal species can be favoured by the extreme conditions induced by global change, as they can exhibit remarkable physiological adaptations. This review highlights the need to incorporate studies on taxonomy,

“…Dominant species patterns and biomass values indicated that the larger fauna took considerably longer than the smaller taxa to recover (Shimmield et al, 2010;Hughes et al, 2015). In Indonesia, Gwyther et al (2009) investigated the recolonization potential of meiofauna on tailings from the Batu Hijau copper and gold mine, deposited at 3000 m depth in a submarine canyon. While the results suggested potential for full recovery of the meiofaunal community after less than 29 weeks, the experiments were conducted in a shallow (diving depth) area under the assumption that the recolonization potential by meiofauna would be similar in terms of community recovery but faster than that occurring at 3000 m (Gwyther et al, 2009).…”

Gwyther (2004) also reported high recolonization rates of meiofauna to sediments affected by discharges of jarosite residue from zinc smelting at over 2000 m depth.…”

“…Mostly, microcosm studies have been focused to explain the relationship between environmental stresses, such as reclamation, contamination, or physical disturbance under field and experimental conditions, and community responses for benthic organisms [5][6][7][8]. However, ecological information including recruitment and survivals of benthic organisms was not clearly specified with salinity limit which definite damage was caused to benthic organisms [9].…”

A B S T R A C TThe brine discharge from seawater desalination has a strong impact on marine community, especially benthic community near brine outlet. The aim of this study is to examine the effect of brine discharge over soft bottom benthic community and changes of sediment quality by periodic brine exposure and water circulation confinement using small-scale benthic microcosms. Transparent acrylic cylinder (1 m in length and 0.5 m in diameter) was used to examine the changes of benthic community structure and sediment quality in microcosm. Salt bags were placed inside of microcosm and the plastic cover partially sealed the open area to maintain salinity at a certain level. Various chemical and biological parameters were analyzed using the sediment samples collected with every two-week interval for 12-week experiment. Major estimated parameters were sediment chemical oxygen demand and total sulfur concentration for sediment quality, and meio/macrobenthic community structure for biological parameters. There were significant differences in some parameters in terms of sediment quality and benthic assemblages between treatment effects. This microcosm approaches to investigate brine impacts of benthic assemblages can a useful tool for gapping between laboratory and field estimations and also to make decision for permitting the level of brine to marine ecosystem.
