“…Stimulation of selected nematode species has been observed in several studies of trace metals (GyeduAbabio & Baird 2006;Austen et al 1994;Mahmoudi et al 2007), hydrocarbons (Coull et Chandler 1992;Peterson et al 1996;Carman et al 1997;Beyrem et Aďssa 2000;Mahmoudi et al 2005) lubricants (Thompson et al 2007;Beyrem et al 2010) and pesticide (Boufahja et al 2011). These species take advantage of the stressed situation at a particular site to dominate in numbers at the expense of other nematode species.…”

Impacts of permethrin contamination on nematode density and diversity: A microcosm study on benthic meiofauna from a Mediterranean coastal lagoon

et al. 2012

A microcosm experiment was used to examine the response of nematode in terms of density and diversity at different levels of permethrin contamination. The sediments were contaminated with three permethrin concentrations [P1: low (5 mg kg −1 ), P2: medium (25 mg kg −1 ) and P3: high (250 mg kg −1 )] and the effects were evaluated after 30 days. The results from univariate and multivariate analyses showed significant differences between nematode assemblages from uncontaminated control and those from permethrin treatments. All univariate indices changed significantly at all the levels of permethrin contamination. In fact, the total nematode abundance (I), Shannon-Weaner index (H ), species richness (d), evenness (J ) and number of species (S) decreased significantly in all the contaminated microcosms. In addition, the results from multivariate analyses of the species abundance data demonstrated that permethrin affects the responses of nematode species. These significant modifications in nematode community structures with response to permethrin contamination were the consequences of a different specific tolerance to this pesticide. Thus, Araeolaimus bioculatus, Calomicrolaimus honestus, Oncholaimus campylocercoides and Theristus pertenuis characterized by increased abundances in all treated replicates, appeared to be "permethrin-resistant" species. Daptonema trabeculosum was eliminated in all the doses tested and seemed to be a very sensitive species to permethrin contamination.

The effects of two lubricating oils on nematode assemblages of a Tunisian lagoon were investigated in a microcosm experiment. Sediment from a pristine site in Ghar El Melh lagoon (Western Mediterranean) was treated with either mineral oil (Mobil 20 W-50), a synthetic lubricant (Mobil 0 W-40), the same two lubricants after use in a vehicle, and effects were examined after 5 weeks. Univariate analysis showed significant differences between most univariate indices of the nematode assemblages in all the lubricant treatments as compared to the control. Total nematode abundance (I), species richness (d) and number of species (S) decreased significantly in all lubricant contaminated microcosms. However, evenness was not affected in all treated replicates except in used mineral lubricant treatment where it was significantly higher than in the control. Diversity (H') was only altered in synthetic lubricant treatments. Results from multivariate analyses of the species abundance data demonstrated that responses of nematode species to the two lubricants treatments were varied: Daptonema trabeculosum was eliminated in all lubricant treatments and seemed to be an intolerant species to oil contamination. Spirinia gerlachi increased in mineral lubricant treatments ("clean" and used) but was eliminated in all synthetic lubricant treatments. This species could be categorized as "resistant" to mineral oil contamination and intolerant to synthetic lubricant contamination. Terschellingia longicaudata increased only in synthetic lubricant treatments ("clean" and used) and appeared to be a "synthetic oil-resistant" species.

“…In field and laboratory experiments, Lenihan and Oliver (1995) observed that N. dimorphus was consistently absent from sediments in Winter Quarters Bay in comparison with uncontaminated sediments. Thompson et al (2006) showed a direct correlation between reduced N. antarcticus larval recruitment rates and presence of oil contaminants in sediment mesocosms placed at various depths at Casey Station, Antarctica.…”

“…However, it is possible that disturbance from anthropogenic and natural sources may play a role in the distribution pattern of both species by limiting suitable habitat and increasing competition for shared food resources and habitat. Pollution at McMurdo Sound may also restrict the range of both species by reducing faunal recruitment (Thompson et al 2006;Conlan et al 2010). Natural impacts from ice scour further reduce habitat and food availability at shallower stations (Dayton et al 1970).…”

Distribution of two species of the genus Nototanais spp. (Tanaidacea) in Winter Quarters Bay and waters adjoining McMurdo Station, McMurdo Sound, Antarctica

Nototanais is the most commonly found peracarid crustacean genus in Antarctic waters. The only two species in the genus, Nototanais dimorphus and Nototanais antarcticus, have been found to have overlapping circumpolar distributions in depths from 7 m to 585 m around Antarctica. However, only one species, N. dimorphus, has been recorded during yearly sampling from 2000 to 2010 at nine shallow (12-36 m) benthic pollution monitoring sites in Winter Quarters Bay and waters adjoining McMurdo Station, McMurdo Sound, Antarctica. These stations varied by depth, anchor ice formation and anthropogenic contamination. In 2011 and 2012, 1071 specimens of Nototanais spp. were collected and separated by species, gender and life stage. N. antarcticus was confirmed to cooccur with N. dimorphus at four of nine long-term monitoring sites. One station had no occurrences of either species. N. antarcticus was found in very low abundances in relation to N. dimorphus, indicating that individual species distributions may be modified by pollution and anchor ice, among other biological factors.
