“…The mean abundance of meiofauna, or meiofaunal density, averaged over the survey period was 614.4 Inds./10 cm 2 . This value falls within a smaller range compared to the meiofauna abundance reported in the intertidal zone of the West Sea, which ranged from 1,521 to 7,849 Inds./10 cm 2 , with a mean abundance of 4,161 Inds./10 cm 2 (Kim et al 1998). Similarly, in the intertidal zone of Daebudo, Korea, the range of meiofauna abundance was 30 to 1,382 Inds./10 cm 2 , with a mean abundance of 751 Inds./10 cm 2 (Min et al 2006).…”

This study aimed to investigate the meiofauna community characteristics in coastal waters highly affected by ocean acidification. Therefore, the meiofauna communities in the coastal waters of Hupo in Uljin-gun, a county bordering the East Sea of Korea, were monitored over five years. During the study period, the mean abundance of total meiofauna communities expressed in population density was 614.4 individuals (Inds.)/10 cm2, similar to the reported meiofauna abundance in the subtidal zone in the Yellow Sea of Korea, an area with sandy sedimentary facies. The most dominant taxa were nematodes (65–70%) and harpacticoids (7–20%); these two taxa accounted for approximately 80% of the total meiofauna abundance. Among the stations studied, station (St.) 10 showed the lowest seawater pH value, and in 2011, when the measured pH was the lowest at 7.82, St. 10 showed the lowest abundance values for total meiofauna and harpacticoids in the 5-year period. To examine the effect of ocean acidification on meiofauna communities at the species level, species of nematodes, the most dominant taxon, were analyzed. The results indicated that the number of nematode species at St. 10 in 2009, when the pH value was low, was 8, which was very low compared to that in the other years of the study period. According to the feeding type, epistrate feeders (2A) accounted for a remarkably high proportion at St. 10, which showed a low pH. This study provides various data on meiobenthic community characteristics to understand the effects of ocean acidification on coastal ecosystems.

“…Most of the time, they are reported together with other ecological parameters such as diversity indices and community structure (e.g., Alves et al 2013;Baguley et al 2015;Carman et al 2000;Elarbaoui et al 2015;Frontalini et al 2011;Huang et al 2005). Nevertheless, quite often, these are the only data provided in pollution studies (e.g., Bertocci et al 2019;Bohórquez et al 2013;Dal Zotto et al 2016;Gao and Liu 2018;Kim et al 2014;Montagna et al 2013;Morad et al 2017;Pereira et al 2017;Riera et al 2013;Sun et al 2014).…”

Índice nematodo/copépodo y las abundancias de nematodos y copépodos como bioindicadores de contaminación: un meta-análisis

A��.Meiofauna has been considered a suitable group for monitoring pollution effects. Based on different pollution tolerance, a nematode/copepod ratio was proposed as an easy tool for monitoring the effect of anthropogenic activities. Although the validity of this tool has been subject to debate due to controversial results, it is still widely used. To establish a general pa�ern in the response of the ratio and nematode and copepod abundances to the effects of organic enrichment, oil pollution and metal enrichment in the marine environment, we conducted a global-scale meta-analysis. The database consisted of 715 pairs of data obtained from 46 studies published during the last 39 years. We could not find a general trend in the response of nematode and copepod abundances to these pollutants. Regarding the ratio, the only significant difference we found is under the effect of oil pollution. However, this difference appears to be an artifact due to publication bias. The information gathered in this study suggests that the ratio and mean abundances are not reliable tools for monitoring purposes.

The community structure of meiobenthos was investigated from seasonal surveys at four stations of Keunso Bay in Taean. Samples of meiobenthos were collected in August, October, 2013 and January, April, 2014. Triplicate faunal samples were collected by using an acryl corer with a 3.6 cm diameter at each station. The mean grain size of the study area ranged from 3.65 ø to 6.35 ø. Total 13 meiofaunal groups were found in the study area. The total density of meiobenthos at each station was be 1,521-7,849 ind./10 cm 2 . Nematodes were the most dominant faunal group at all stations. The subdominant group were Sarcomastigophorans and benthic harpacticoid copepods. The highest meiofaunal density was shown in spring, whereas the lowest density was recorded in summer. A total of 13 meiobenthic taxa were found, the richest taxa in October at station 2 (13 ind./10 cm 2 ), and the lowest in April at station 4 (5 ind./10 cm 2 ). There were seasonal fluctuations in the number of meiobenthic taxa decreasing from summer to spring. The density of meiobenthos gradually decreased as the depth of sediment increased. Seasonal changes in the vertical distribution of meiobenthos in the study area occurred mainly near the sediment surface.
