“…Other studies (Rosenberg; In this context, inventories of oligochaete fauna and ecological relationships between species and the environment are very important for the formulation of biodiversity conservation policies, especially in tropical environments (Christoffersen, 2010;Alves, 2018). Studies of oligochaete assemblage patterns can be useful to predict changes along environmental gradients, as well for standardized methods for testing organisms in ecotoxicological studies (Castro et al, 2020;Suriani et al, 2007;Behrend et al, 2012). However, oligochaete species surveryed and systematics studies still are scarce in Brazilian environments, probably due to the lack of specialists in the taxonomic identification of these worms.…”

This work sought the survey of species and information about the distribution of the Class Oligochaeta in reservoirs sampled in the Sediment Quality Monitoring Network of CETESB (Environmental Company of the State of São Paulo). As such, this study aimed to inventory the limnic oligochaetes fauna to expand knowledge of the ecology and distribution of this group in reservoirs in the state of São Paulo. Ninety replicates were performed in 12 reservoirs in the state of São Paulo between 2014 and 2016, using van Veen or Ponar samplers in the sublittoral region, and Ekman-Birge in the deep region. Twenty-eight taxa were inventoried, belonging to the families Naididae and Opistocystidae. The species Dero righii and Pristina longisoma were recorded for the first time in São Paulo State, Nais magnaseta and Spirosperma velutina were first recorded in Brazil. The results presented here make this inventory extremely important for understanding the distribution of aquatic oligochaetes throughout the Brazilian territory.

“…Earthworms are the most used organisms in terrestrial bioassessments in Latin America (Niemeyer et al 2017). In this sense, oligochaetes have played an important role as bioindicators of pollutant toxicity due to their sensitivity to specific toxicants and certain tolerance to pollution (Chapman 2001;Sivakumar 2015;Castro et al 2020a;Castro et al 2020b;Felipe et al 2020).…”

Soil toxicity tests are commonly applied using Enchytraeus crypticus to analyze reproductive outputs. However, the traditional method for counting potworms takes a long time due to the significant number of offspring. This paper compares the conventional total counting of E. crypticus juveniles (M1) and an alternative methodology (M2). The proposed methodology (M2) uses a simple random counting method (1/4) for the partial counting of juveniles and total estimation. Chronic bioassays (21 days of exposure) were performed in tropical artificial soil (TAS) using sugarcane vinasse as a hazardous substance. Comparing the final density of juveniles recorded in M1 and M2, no statistical differences were pointed out in either one. Applying analyses based on effective concentration (EC10 and EC50), no statistical differences were identified there either. The t-test showed that there was no statistical difference between the counting methods (M1 and M2) in each treatment (control and dilutions). Moreover, we ran the Tukey test for M1 and M2 methods separately and observed that 100 % of the vinasse showed a statistical difference compared to the control treatment in both (p ≤ 0.05), affirming that independent of the counting method, the ecotoxicological outputs were similar. Therefore, the proposed alternative is a suitable method for bioassay using. E. crypticus in tropical artificial soil, decreasing to 1/4 the total time required for counting.

“…Esses dados são comparados com níveis tóxicos presentes na literatura, desconsiderando a sensibilidade de diferentes organismos, a interação dos compostos tóxicos com o meio, a biodisponibilidade e a presença de diferentes compostos tóxicos(ALEXANDER, 2000;DE ZWART;POSTHUMA, 2005; O'HALLORAN, 2006). Allonais inaequalis Stephenson, 1911 (Oligochaeta: Naididae) é espécie nativa (ver Capítulo 1) utilizada em bioensaios por possuir tolerância a diferentes condições do meio, desde os mais impactados até os mais preservados e, por serem de fácil obtenção e manutenção, além de suas ocorrências nos corpos hídricos brasileiros (SMITH; KENNEDY;DICKSON, 1991; CORBI, GORBI, CORREA, 2015;CASTRO et al, 2020b;FELIPE et al, 2020) Os vegetais Lactuca sativa (Linnaeus, 1753) e Eruca sativa (Linnaeus, 1753) são comumente utilizados em testes de fitotoxicidade devido a sua sensibilidade aos contaminantes, rápida germinação, baixo custo e por serem consumido em diversos países(CHANDLER et al, 2020;DE PAIVA PINHEIRO et al, 2020;LI et al, 2020;MARTINS; MOURATO, 2020; SHARIATINIA et al, 2021; WAHID et al., 2021).…”
