“…More recently, and on the basis of bibliographic analysis, Frontalini & Coccioni (2011) were able to synthetize the inferred sensitive or tolerant response of many foraminiferal species and genera to pollution. Although most of these inferences are not yet supported by the results of laboratory experimentation, a high degree of tolerance to trace elements has been inferred for several taxa, including Ammonia, Cribroelphidium, Haynesina, Brizalina and Bolivina, as also reported by other researchers (Armynot du Châtelet & Debenay, 2010;Armynot du Châtelet et al, 2004;Carnahan et al, 2008Carnahan et al, , 2009Yanko et al, 1999). In recent years, several studies have focused on the response of particular benthic foraminiferal species to selected trace elements in controlled laboratory conditions (e.g.…”

“…Following Armynot du Châtelet et al (2004), only taxa with a relative abundance exceeding 5% in at least one sample were taken into consideration. However, though rare species often considered the most sensitive ones were down-weighted in this way, their contribution in the TE system was measured by means of MI calculation.…”

Summary:This study was conducted in Lake Varano (southern Italy) in order to determine the environmental parameters that influence nematode taxonomic and functional diversity and how they influence them, and to classify for the first time the ecological quality status of a transitional environment. The general composition and level of taxonomic diversity were comparable with those reported for transitional environments worldwide. Principal component analysis revealed that the main environmental factors controlling the assemblages in terms of both composition and biological traits were grain size, organic matter, pollution load index and, only secondarily, salinity. Molgolaimus allgeni, Terschellingia longicaudata and Leptolaimus luridus showed higher values in relation to silt, organic matter and pollution load index, while Axonolaimus caudostriatus, Odontophora wieseri, Paramonhystera pellucida and Paracanthonchus longicaudatus showed higher values in relation to the redox potential and sand percentage. Salinity was detected as an influencing parameter only secondarily and particularly for Calomicrolaimus honestus, Daptonema normandicum, Thalassomonhystera parva and Sabatieria pulchra. With respect to functional traits, the trophic groups seemed to be mainly related to sediment type, which is in turn reflected by the nature of the available food. The maturity index, as well as c-p classes, did not always permit a clear interpretation of the interaction between anthropogenic and natural factors. However, the greater influence of the San Antonino and San Francesco Canals was perfectly revealed by the nematode assemblage. In accordance with the current ecological quality classes, Lake Varano can mainly be classified as having good to poor ecological quality status.Keywords: free-living nematodes; biodiversity; transitional environment; ecological quality; Lake Varano.La comunidad de nematodos de una laguna costera (Laguna de Varano, Italia meridional): patrones de la ecología y la biodiversidad Resumen: Este estudio tiene como objetivo analizar cuál y en qué medida los parámetros ambientales influyen en la diversidad taxonómica y funcional de los nematodos y clasificar por primera vez el Estado de la Calidad Ecológica (EQS) de un ambiente de transición como la laguna de Varano (Italia meridional). La composición y el nivel de divesidad taxonómica son comparables con los reportados en todo el mundo para TEs. El análisis de componentes principales reveló que los factores que controlan la composición y las características biológicas de las comunidades son el tamaño del gránulo, la materia orgá-nica (MO), el índice de aportes contaminados (PLI) y sólo secundariamente la salinidad. Molgolaimus allgeni, Terschellingia longicaudata y Leptolaimus luridus aumentan en número en relación con el limo, la MO y el PLI, mientras Axonolaimus caudostriatus, Odontophora wieseri, Paramonhystera pelúcida y Paracanthonchus longicaudatus muestran valores más altos en relación con el potencial redox y el porcentaje de arena.

“…Offshore nematode communities appear to be more susceptible to metals than near-shore communities (Austen and McEvoy 1997). High levels of heavy metals potentially generate test deformities in benthic foraminifera and modify community structure (e.g., Alve 1995;Ruiz et al 2004;Armynot du Châtelet et al 2004;Ferraro et al 2006;Le Cadre and Debenay 2006). In an experimental study, Alve and Olsgard (1999) found that foraminifera were able to colonise sediments that were severely contaminated with copper.…”

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,
