“…in higher numbers (Table 2). Because this species generally inhabits muddy habitats containing low levels of particulate organic matter (Campitelli‐Ramos et al, 2014), it is not surprising to find Dero sp. in higher numbers in Bolgoda Lake, which is less polluted compared to Beira Lake.…”

Studies addressing the macrobenthic diversity and their potential as bioindicators in water quality assessment programs are sparse for Sri Lanka. The present study investigated the macrobenthic diversity in relation to water quality parameters in some urban reservoirs in the Western Province of Sri Lanka, assessing their potential as bioindicators in water quality assessment programs. The six study reservoirs included the Ihalagama Tank, Peralanda Tank, Kesbewa Tank, Boralesgamuwa Tank, Bolgoda Lake and Beira Lake. The microbenthic fauna abundance at randomly selected locations (n = 9) in each reservoir and selected water quality parameters (temperature; pH; electrical conductivity; total dissolved solids; BOD 5 ; dissolved nitrates; total dissolved phosphate and alkalinity of the overlying water at each location were measured between July 2020 and January 2021, using standard data collection methods). The species richness (SR), species heterogeneity (H′) and species evenness (J) of the macrobenthic fauna in each reservoir were calculated, and the abundance and water quality data analysed using ANOVA and PCA as appropriate. A total of 13 macrobenthic taxa (Glyphidrilus sp., Limnodrilus socialis, Dero sp., Stratiomyd larva, Chironomid larva, Bellamya sp., Melanoides tuberculata, Gyraulus sp., Lymnaea sp., Paludomus sp., Thiara sp., Ancylus sp. and Mesostoma sp.) were observed from the six study reservoirs. The oligochaete tubificid worm L. socialis dominated the sediment samples, accounting for more than 94.7% of the total macrobenthic abundance, with the highest relative abundance of this species observed in Beira Lake (99.3%). The species richness of the macrobenthic community was highest in the Ihalagama and Kesbewa tanks (SR = 5), while it was the lowest in the Peralanda Tank (SR = 2). Since the benthic community was mainly dominated by L. socialis, the lowest species heterogeneity and species evenness values were observed in Beira Lake (H′ = 0.05; J = 0.03). The values of the water quality parameters among the study reservoirs varied, with Beira Lake exhibiting significantly high BOD 5 , dissolved nitrate, and total dissolved phosphate values (p < .05) than the other reservoirs, indicating a higher degree of eutrophication. Furthermore, the SR, J and H′ values for the study reservoirs decreased with increasing BOD 5 , dissolved nitrate and total dissolved phosphate levels. Thus, it was concluded that the abundance and diversity of macrobenthic fauna are primarily governed by water quality parameters. Furthermore, L. socialis can be used as a potential bioindicator organism in water quality assessment programs in urban reservoirs.

ResumoOligochaeta (Annelida: Clitellata) associados a macróitas aquáticas no Brasil. Oligoquetos ainda são caracterizados como um grupo pouco estudado dentre os macroinvertebrados aquáticos e poucos estudos sobre sua ecologia foram realizados no Brasil. Assim, nosso estudo objetivou fornecer um panorama da associação entre Oligochaeta e macróitas, em ambientes aquáticos continentais brasileiros, por meio de uma revisão da literatura junto a um inventário de espécies associadas a macróitas aquáticas em lagoas marginais da represa Ribeirão das Anhumas (Américo Brasiliense-SP). Na revisão, analisamos 10 artigos, nos quais obtivemos dados sobre 41 espécies. Amostramos, ainda, cinco gêneros de macróitas, Egeria, Salvinia, Utricularia, Eleocharis e Ceratophyllum, em agosto e dezembro de 2012 e em março e abril de 2013, na represa Ribeirão das Anhumas. Registramos 21 espécies de Oligochaeta associadas a essas macróitas. Com os dados obtidos na revisão junto ao inventário da represa Ribeirão das Anhumas, evidenciamos o total de 41 espécies associadas a macróitas aquáticas, com maior riqueza da família Naididae (93,33%), seguida por Opistocystidae (4,44%) e Alluroididae (2,22%). Nosso estudo inventariou cerca de 48% da diversidade de Oligochaeta registrados em ecossistemas continentais no Brasil, destacando, assim, a importância das macróitas como recurso para esses invertebrados, principalmente para a família Naididae.Palavras-chave: Ecossistemas de água doce; Fauna associada; Lista de espécies; Microdrili AbstractOligochaeta are still characterized as a poorly studied group among the aquatic macroinvertebrates and few studies about their ecology were conducted in Brazil. Thus, our study aimed to provide an overview of the association between Oligochaeta and macrophytes, in Brazilian continental aquatic environments, by means of a literature review along with an inventory of species associated to aquatic macrophytes on marginal lagoons in the reservoir Ribeirão das Anhumas (Américo Brasiliense, São Paulo, Brazil). In the review, we analyzed 10 articles, where we obtained data on 41 species. We also sampled 5 macrophyte genera, Egeria, Salvinia, Utricularia, Eleocharis, and Ceratophyllum, in August and December 2012 and in March and April 2013, in the reservoir Ribeirão das Anhumas. We registered 21 Oligochaeta species associated to these macrophytes. With the data obtained in the review along with the inventory of the reservoir Ribeirão das Anhumas, we found a total of 41 species associated to aquatic macrophytes, with a higher richness of the Naididae family (93.33%), followed by Opistocystidae (4.44%), and Alluroididae (2.22%). Our study inventoried about 48% of the Oligochaeta diversity registered in continental ecosystems in Brazil, thus highlighting the signiicance of macrophytes as a resource for these invertebrates, mainly for the Naididae family.
