“…Darrigran et al (1998) also verified that the colonization by L. fortunei on solid surfaces (e.g., rocks) increased Oligochaeta colonization because of the increase in surface complexity. The increase in the abundance of detritivorous taxa, mostly Chironomidae and Naididae, probably increases the food resource availability, as well as release and disposal of wastes from mussels.…”

We conducted a study about invertebrates on artificial substrates with different antifouling paints in order to answer the following questions: 1) is there lower accumulation of organic matter on substrates with antifouling paints, 2) is invertebrate colonization influenced by the release of biocides from antifouling paints, 3) is the colonization of aquatic invertebrates positively influenced by the material accumulated upon the substrate surface and 4) is the assemblage composition of invertebrates similar among the different antifouling paints? To answer these questions, four structures were installed in the Baía River in February 1 st , 2007. Each structure was composed of 7 wood boards: 5 boards painted with each type of antifouling paints (T1, T2, T3, T4 and T5), one painted only with the primer (Pr) and the other without any paint (Cn). After 365 days, we observed a greater accumulation of organic matter in the substrates with T2 and T3 paint coatings. Limnoperna fortunei was recorded in all tested paints, with higher densities in the control, primer, T2 and T3. The colonization of Chironomidae and Naididae on the substrate was positively influenced by L. fortunei density. The non-metric multidimensional scaling (NMDS) of the invertebrate community provided evidence of the clear distinction of invertebrate assemblages among the paints. Paints T2 and T3 were the most similar to the control and primer. Our results suggest that antifouling paints applied on substrates hinder invertebrate colonization by decreasing the density and richness of invertebrates.Keywords: colonization, biofouling, Limnoperna fortunei. Influência de revestimentos antiincrustantes em invertebrados aquáticos (Mytilidae, Chironomidae and Naididae): densidade, riqueza e composição ResumoO estudo dos invertebrados em substrato artificial com diferentes revestimentos antiincrustantes foi realizado com o intuito de responder as seguintes questões: 1) Há menor acumulação de material orgânico nos substratos com revestimentos antiincrustantes? 2) A colonização de invertebrados é afetada pela liberação de biocidas dos revestimentos antiincrustantes? 3) A colonização dos invertebrados aquáticos é facilitada por material acumulado sobre a superfície do substrato? 4) A composição da assembléia é similar entre os diferentes revestimentos? Para realização deste estudo, quatro estruturas foram instaladas em 01 de fevereiro de 2007 no rio Baía. Em cada estrutura foram colocadas sete placas de madeira: cinco placas com aplicação de um tipo de revestimentos antiincrustantes (T1, T2, T3, T4 e T5), uma placa apenas com a aplicação do primer (Pr) e a outra placa permaneceu sem aplicação de nenhum revestimento (Cn). Ao final dos 365 dias em que os substratos ficaram submersos observou-se maior acumulação de material orgânico nos substratos dos revestimentos T2 e T3. Limnoperna fortunei foi registrada em todos os revestimentos testados, com maiores densidades encontradas no controle, primer, T2 e T3. A colonização de Chironomidae e Naididae sobre os...

“…In the current context of globalization, biological invasions constitute one of the main threats to biodiversity (Bellard et al, 2016;Essl et al, 2020). Invasive bivalves cause biotic and structural changes that influence aquatic macroinvertebrate assemblages (Darrigran et al, 1998;Darrigran and Damborenea, 2011;Wittmann et al, 2012;Werner, 2014). The final impact of each invasion on these organisms is difficult to predict (Lodge, 1993).…”

The invasion of the Asiatic clam Corbicula fluminea in South America has already reached Patagonia. Despite the well-known direct and indirect impacts that this species exerts on fresh-water ecosystems, particularly on benthic communities, few studies have been undertaken on its effect on the composition and structure of aquatic macroinvertebrate assemblages. This study evaluated the effects of the invasion of the Asiatic clam C. fluminea on the aquatic macroinvertebrate assemblages of the Limay River, one of the most important rivers of the arid plateau of Argentinian Patagonia. As this river is currently in the process of being invaded, it was possible to compare invaded and non-invaded sites. Invaded sites displayed a certain homogenization of their constituent species and functional composition. Non-metric multidimensional scaling, similarity analysis and similarity percentages showed negative or positive influence of the presence of this species on the abundance of some taxa, due to competition for resources in this low-productivity Patagonian ecosystem. The deposition of the faeces and pseudo-faeces of C. fluminea enriches the organic content of the sediments. However, its pedal feeding can function as a competitive strategy: by consuming its own deposited organic matter when food is scarce, the amount available to other macroinvertebrates is reduced. This paper is the first contribution on the impact of this invasion on northern Patagonia’s aquatic macroinvertebrate assemblages.

“…Oligochaeta species richness is directly related to food availability (Collado and Schmelz, 2001) and quality (Pasteris et al, 1994;Collado and Schmelz, 2001), substrate type (Verdonschot, 2001;Bletter et al, 2008), oxygen availability (Collado et al, 1999;Nijboer et al, 2004), and biological interactions (Darrigran et al, 1998). In addition, this group presents a low dispersion, and most of them are considered indicators of specific habitats (Verdonschot, 2001), of hydro-morphological character (Verdonschot, 2001), and of trophic state (Suriani et al, 2007).…”

Using oligochaeta assemblages as an indicator of environmental changes

We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta assemblage along the Iguaçu River. Changes in environmental variables and in richness and composition of Oligochaeta were summarized by Canonic Correspondence Analysis. Along the Iguaçu River, conductivity, and altitude decreased, whereas temperature increased. Oligochaeta composition showed a significant spatial variation, with higher abundances of the family Tubificidae and the genus Dero (Naididae) occurring in the First Plateau. In the Second and Third plateaus, few species were dominant, with increases in the presence of species of Naididae below dams. We found a clear decrease in species richness along the Iguaçu River. Moreover, we found that Oligochaeta assemblage was influenced by some environmental variables such as altitude, conductivity, substrate type and temperature, and by anthropogenic activities (human occupation and damming). The results supported the use of Oligochaeta as surrogate taxa to predict environmental changes along impacted (dammed and eutrophic) rivers. The validity of this was indicated by the strong and significant gradient registered, from the headwater to mouth of the Iguaçu River.Keywords: surrogate taxa, reservoir cascade, geomorphologic gradient, human occupation, Iguaçu River. Usando assembléias de Oligochaeta como um indicador de mudanças ambientais ResumoFoi delineada uma pesquisa de campo (toda extensão do rio; não barrado: Primeiro e Segundo planaltos; barrado: Terceiro planalto) para testar a hipótese de que a cascata de reservatórios promove redução na riqueza de espécies e muda a composição da assembléia de Oligochaeta ao longo do Rio Iguaçu. Mudanças nas variáveis ambientais e na riqueza e composição de Oligochaeta foram sumarizadas por Análise de Correspondência Canônica. Ao longo do Rio Iguaçu, a condutividade e a altitude diminuíram, enquanto a temperatura aumentou. A composição de Oligochaeta mostrou variação espacial significativa, com maiores abundâncias da família Tubificidae e do gênero Dero (Naididae) ocorrendo no Primeiro planalto. No Segundo e Terceiro planaltos, poucas espécies foram dominantes, com aumento na presença de espécies de Naididae abaixo de barragens. Foi encontrada uma clara diminuição na riqueza de espécies ao longo do Rio Iguaçu. Além disso, observou-se que a assembléia de Oligochaeta foi influenciada por algumas variáveis ambientais, como altitude, condutividade, tipo de substrato e temperatura, e por atividades antropogênicas (ocupação humana e barramento). Os resultados deste estudo suportam o uso de Oligochaeta como táxon substituto para predizer mudanças ambientais ao longo de rios impactados (barrados e eutróficos). A validade desse estudo foi indicada pelo forte e significativo gradiente, registrado da cabeceira à foz do Rio Iguaçu.Palavras-chave: taxon substituto, cascata de r...
