“…The study by Sharma et al (2012) from the Gulf of Mexico examined sites with significant depth variation, extending from the continental shelf to the deep communities with a depth range of 212-3000 m. Our results did not support a relationship between depth and nematode assemblage nMDS coordinates, though one of the nematode feeding types (2A-epistrate feeders) had a significant negative correlation with depth. Epistrate feeders are thought to primarily graze on diatoms and other microalgae (Moens et al 2014), a food source that would be less available with increasing depth. When eastern and western sites were analyzed separately, the western locations revealed a strong correlation with decreasing epistrate feeders (primarily a decrease in the genus Dorylaimopsis), and increasing deposit feeders (1A þ 1B) with depth.…”

“…It has been demonstrated that meiofauna, including foraminifera, are good indicators of the health of coastal marine (Vassallo et al 2006;Balsamo et al 2012;Schönfeld et al 2012;Moens et al 2014). In recent decades, a growing body of scientific literature has been dedicated to the response of meiofauna to anthropogenic impacts, such as pollution (Coull and Chandler 1992;Fleeger and Carman 2011;Balsamo et al 2012;Moens et al 2014).…”

Meiofauna reflect changes derived from environmental disturbance, both spatially and temporally (Moreno et al 2008), and can be considered a collective indicator of environmental quality since they display specific responses to different types of anthropogenic disturbance (Schratzberger and Warwick 1999;Danovaro et al 2004b).…”

“…Larger organisms, such as bivalves and crustaceans, suffer high mortality with long recovery times (Kaiser et al 2006), whereas smaller meiofaunal taxa appear to have higher resilience to these disturbances (Jennings et al 2001). Most studies have focused on megafauna and macrofauna, and relatively little is known about the impact of bottom trawling on meiofaunal communities (Moens et al 2014). In general, meiofauna were less affected than macrofauna by physical disturbance, as in the case of sediment modifications due to the passage of large cruise liners (Warwick et al 1990).…”

Is the meiofauna a good indicator for climate change and anthropogenic impacts?

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,

“…Fine sediments are generally characterized by the families Desmodoridae and Linhomoeidae, while coarse sediments are dominated by the families Enchelidiidade, Xyalidae, Cyatholaimidae, and Chromadoridae (Wieser 1959;Heip et al 1985;Fonseca and Fehlauer-Ale 2012;Maria et al 2013;Moens et al 2013). Although distinct assemblages along the spectrum occur, we still do not know how these changes occur.…”

The majority of studies have advocated that diversity of marine nematodes increases with increasing sediment grain size, although the opposite trend has also been suggested. The controversy is partially caused by not taking into account the effect of density on patterns of diversity and by analyzing datasets from different environments. The present study investigated nematode assemblages from sediments varying from very fine sand (mean grain size of 0.12 mm) to very coarse sand (1 mm) in shallow sublittoral marine environments. Contrary to previous studies, species richness was constant along the granulometric spectrum, despite significant changes in composition. The dominant genera were separated into five groups according to their optimum distribution and there was little overlap between these groups. Concepts from the niche theory explain to some extent the observed patterns. For instance, some of the coexisting genera were from different feeding types.
