“…12,13,31 Remarkably, laboratory results demonstrated some oligochaetes (e.g., Limnodrilus hoff meisteri) were capable of surviving crude oil concentrations that exceeded 16000 mg/ kg. 34 The lower abundance of stoneflies and other sensitive groups at downstream sites was probably not a direct result of continued exposure to residual hydrocarbons but more likely a legacy effect of the 2013 spill. Although we detected petroleum hydrocarbons in West Creek sediments, these concentrations were several orders of magnitude lower than those observed in urban streams and well below reported toxic thresholds based on laboratory experiments.…”

“…In West Creek, these relatively long-lived, univoltine (one generation per year) species were replaced by multivoltine (more than one generation per year) dipterans and non-insects, organisms that are noted for much faster rates of reproduction and recolonization following disturbances . The high tolerance and proliferation of these organisms, particularly oligochaetes, have been documented after petroleum spills. ,, Remarkably, laboratory results demonstrated some oligochaetes (e.g., Limnodrilus hoffmeisteri ) were capable of surviving crude oil concentrations that exceeded 16000 mg/kg …”

We integrated the results of field surveys with a mesocosm experiment to quantify the ecological impacts of a gasoline and diesel spill on a third-order stream in western Colorado (United States). The spill caused a massive fish-kill of brown trout (Salmo trutta) and mottled sculpin (Cottus bairdii), which extended several kilometers downstream. Despite significant decreases in petroleum hydrocarbon concentrations, subsequent surveys indicated little recovery of fish populations 4 years after the spill. Benthic macroinvertebrate communities were also affected, yet some metrics commonly used to assess stream ecological integrity (e.g., total abundance and species richness) showed no difference between impacted and reference sites. The failure of some groups to recover 2.5 years after the spill was likely a result of their comparatively slow reproduction and recolonization rates. To support our hypothesis that effects observed in the field resulted from petroleum exposure, we conducted a mesocosm experiment in which benthic macroinvertebrate communities were exposed to a simulated diesel spill. We observed significant decreases in the abundance of most macroinvertebrate groups at the lowest exposure concentration (75 mg/L diesel) and a strong concentration-dependent drift response across all groups. Our study suggests that relatively small petroleum spills can significantly affect stream communities, and these effects may persist several years after sediment concentrations return to background levels.

“…In general, several Naididae are considered to have a high tolerance to organic toxins and may have a strong ability to degrade industrial pollutants. For example, Vorob' ev et al (2010) reported that the aquatic naidid worm Limnodrilus hoffmeisteri Claparède, 1862 survived highly contaminated oil sediment and also had the ability to bioremediate oil from bottom sediment. In the case of microorganisms, efficient bioremediation is dependent on achieving adequate population density, metabolic capability, and physiological activity at the contaminated site (e.g., Sayler et al 1982;Dinesh et al 2015).…”

Morphological and Genetic Characterization of the First Species of <i>Thalassodrilides</i> (Annelida: Clitellata: Naididae: Limnodriloidinae) from Japan

A species of marine limnodriloidine oligochaete, Thalassodrilides cf. briani Erséus, 1992, is recorded from gravelly sand sediments of the subtidal zone in Ehime Prefecture, Japan. The present material agrees with the original description of T. briani, which was first found at Hong Kong, with the exception that the copulatory sacs are oval; not slender. Despite the lack of genetic data for the Hong Kong population, we conclude that the Japanese specimens are conspecific with it, or at least very closely related, based on morphological considerations. This is the first record of the genus Thalassodrilides Brinkhurst and Baker, 1979 in Japan. The phylogenetic relationships between T. cf. briani and three other species of Thalassodrilides are estimated, based on partial DNA sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene and the complete nuclear ribosomal Internal Transcribed Spacer (ITS) region, using two members of the closely related genus Doliodrilus Erséus, 1984 as outgroups. The genetic analysis shows that T. cf. briani is a species delimited by both mitochondrial and nuclear data, and clearly separated from at least its closely related congeners in the Northwest Atlantic (Caribbean and adjacent areas).

Caracterización estructural y funcional de los macroinvertebrados en los bañados de desborde fluvial del área pampeana

En este estudio se caracteriza el ensamble de macroinvertebrados en bañados de desborde fluvial de cuatro arroyos pampeanos bonaerenses con diferentes actividades en el uso del suelo (intensa horticultura y ganadería extensiva) desde un punto de vista estructural y funcional. Se aplicaron índices bióticos, ecológicos, análisis multivariados y se analizaron los ensambles de oligoquetos y quironómidos. Los mayores valores diversidad y riqueza taxonómica de macroinvertebrados correspondieron al bañado de Chubichaminí (H ́= 1,9; S=19,25). Este arroyo presentó aguas ligeramente poluídas, siendo aceptable en términos de calidad del agua. El análisis multivariado ordenó a los sitios de los bañados Del Gato y Carnaval con la mayor carga de nutrientes vinculados a los taxa más tolerantes como los dípteros Stratiomyidae, Ephydridae y nematodes, oligoquetos y gasterópodos Physidae. La mayor diversidad y riqueza de oligoquetos se registró en los bañados del Cajaravillas y Chubichaminí en los meses cálidos y las diferencias encontradas se debieron principalmente a Limnodrilus hoffmeisteri Claparède, 1862. El ensamble de quironómidos estuvo conformado por 24 taxones pertenecientes a Chironominae, Orthocladiinae y Tanypodinae. El género Chironomus Meigen fue más abundante en el A° Del Gato, correspondiendo principalmente a C. calligraphus Goeldi, asociado a ambientes con evidente impacto antrópico. Los sitios estudiados mostraron diferentes patrones en la proporción de grupos funcionales alimentarios sin una clara relación con el uso del suelo. Los índices aplicados en el ensamble de macroinvertebrados resultaron efectivos para evaluar el estado ecológico de los bañados analizados.
