Full textThe intervention of anthropogenic activities to the environment has reflected in the structure and functions of ecosystems and the use of chemical additives, such as pesticides and fertilizers, has contributed for the disequilibrium. The Vertimec® 18EC, whose toxicity is described to different taxa, is widely used in agricultural crops, and it has been known about the intense handling practices, often irregular, which can reach higher concentrations than those expected in the aquatic environment. One group that has been highlighted in recent years by the increasing decline associated with the use of these products is the amphibians. Amphibians plays a central role in the food chain and several studies have related the ecological disequilibrium caused by the decline of this group due to the addition of contaminants, including pesticides. In this study, laboratory bioassays were developed to determine the more susceptible stage and the LC50,96h of Lithobates catesbeianus to Vertimec® 18EC. From these results, in situ experiments (mesocosms) were conducted with tadpoles in more advanced stage (25 of Gosner table) in order to compare the differences in toxicity of Vertimec® 18EC when manipulated both in field and in laboratory. Also, the effects caused by a single and multiple application of the pesticides were evaluated. The laboratorial results showed that earlier stages (21G) were more sensitive than more developing tadpoles (25G), and the effects of the pesticide were more aggressive under natural conditions (mesocoms), with 100% of mortality before 24 hours, at the same developmental stage. The results of laboratorial and in situ bioassays indicated that the lower concentration (0.002 ml Vertimec.L-1) didn\'t cause mortality, but alterations on development stage and larval period time were observed, indicating indirect effects (available resources) on the success of this species. On the other hand, no difference was found between the single and multiple applications of Vertimec® 18EC because all organisms died in the unique dosage treatment, but it was possible to verify limnological alterations after the second application of the pesticide. Considering the results obtained we conclude that Vertimec® 18EC can affect directly (mortality, development stages and behavior) and indirectly (food reduction) the population of Lithobates catesbeianus, contributing to the decline of amphibians in the natural systems.

Estudos sobre saturação de espécies buscam conhecer o papel relativo de fatores locais e regionais sobre a estruturação das comunidades. No caso de comunidades zooplanctônicas, os resultados encontrados são bastante divergentes, tornando necessário o preenchimento de certas lacunas. Uma destas está na comparação entre diferentes tipos de ambiente, como perenes e temporários, que apresentam comunidades com características bem distintas. Lagoas temporárias passam periodicamente por eventos de seca e, considerando organismos aquáticos, este é um dos mais fortes distúrbios experimentados, pois impõe severas restrições fisiológicas e comportamentais. Baseado nestes fatos, este estudo tem como hipótese principal que lagoas temporárias apresentam comunidades zooplanctônicas insaturadas, enquanto lagoas perenes apresentam comunidades zooplanctônicas saturadas. Para testá-la, foi realizado um experimento em mesocosmos onde as comunidades zooplanctônicas destes dois tipos de lagoas foram manipuladas, bem como o evento de dispersão. Os resultados indicam que ambas apresentam-se saturadas e que, portanto, fatores locais são predominantemente mais importantes do que a dispersão (fator regional) sobre a estruturação destas comunidades. Dentre estes fatores locais, os fatores abióticos atuam como filtros selecionadores de espécies e parecem ser mais importantes do que as interações bióticas com as comunidades residentes.
Many studies about species saturation try to find out the relative role of the local and regional factors on the communities structure. Regarding to zooplankton communities, the results obtained are very divergent requiring the filling of certain gaps. One of these gaps is on the comparison between different types of environments, like perennial and temporary which have communities with very different features. Temporary ponds are periodically affected by drought events and, considering the aquatic organisms, this is one of the strongest disturbs that they experienced because it imposes physiological and behavioral restrictions. Based on these facts, the principal hypothesis of this study is that temporary ponds have unsaturated zooplankton communities while permanent ponds have saturated zooplankton communities. To test it, an experiment was made in mesocosms where the communities of both ponds were manipulated as well as the dispersion event. The results indicate that both communities are saturated and therefore local factors are predominantly more important than the dispersion (regional factor) on the structuring of these communities. Among these local factors, the abiotic factors act as species selectors filters and seems to be more relevant than the biotic interactions with the resident species.

Ao longo de décadas, a liberação de dióxido de carbono (CO2), principalmente devido à queima de combustíveis fósseis, aumentou consideravelmente e resultou em um aumento da concentração de CO2 atmosférico. A rápida absorção de energia térmica e de CO2 pelos oceanos resultará em uma série de mudanças concomitantes na bioquímica da água do mar, incluindo reduções no pH e estado de saturação de carbonato. A acidificação dos oceanos representa riscos para todos os ecossistemas marinhos, mas já se sabe que os recifes de coral são amplamente reconhecidos como o ecossistema que é mais ameaçado pela acidificação do oceano. Com isso, o presente estudo teve como principal objetivo investigar os efeitos de diferentes níveis de pH da água do mar, sobre a comunidade de Nematoda de fital dos recifes de coral. Para esta avaliação, um experimento de mesocosmo foi conduzido utilizando unidades artificiais de substrato (UAS) colonizadas pela meiofauna de fital. Os fatores avaliados foram o tempo (com 15 e 30 dias de exposição) e os níveis de acidificação: pH controle (água do mar/ambiente sem manipulação) e três níveis de acidificação (reduções no pH ambiente de 0,3, 0,6 e 0,9 unidade). Ao final do experimento, as amostras foram fixadas, lavadas em peneiras geológicas (500 e 45-μm) e os nematódeos foram identificados a nível de gênero com auxilio de microscópio ótico. Foram identificados 60 gêneros, distribuídos em 7 ordens e 25 famílias. Os resultados mostraram que a estrutura da comunidade sofreu diferenças significativas para os fatores tempo e tratamento, mas não para a interação entre eles. A densidade sofreu diferenças significativas para a interação entre os fatores tempo e tratamento. Já riqueza dos gêneros, sofreu redução entre os tratamentos de pH 7,5 e 7,2. Apenas o gênero Chromadora se mostrou mais sensíveis ao experimento, que teve resposta significativa para o fator tempo, com redução de sua densidade. Para os grupos tróficos da comunidade foram encontradas diferenças significativas para os dois fatores e para a interação entre eles, já para o Índice de Diversidade Trófica (IDT) os resultados da ANO VA indicaram que apenas o fator tempo foi significativo. O Índice de Maturidade (IM) não apresentou resultados significativos para nenhum dos fatores. Os resultados apresentados mostraram que os efeitos podem ser complexos, com respostas positivas e negativas, devido à vulnerabilidade diferencial dentro e entre os grupos genéricos de nematódeos mostraram ainda que o funcionamento da comunidade consegue resistir a este tipo de impacto, pelo menos, na escala de variação do pH adotada neste experimento.
The carbon dioxide (CO2) release, mainly due to burning fossil fuels, increased considerably during the last decades and resulted in an increase in atmospheric CO2 concentration. The rapid absorption of CO2 and thermal energy by the oceans will result in a series of concurrent biochemical changes in seawater, including reductions in pH and carbonate saturation state. Despite the increasing risk that ocean acidification will modify benthic communities, great uncertainty remains about how this impact will affect the lower trophic levels, such as members of the meiofauna and of the Nematofauna. A mesocosm experiment was conducted to investigate the effects of water acidification on a phytal Nematofauna community from a coral reef. Community samples collected from the coral reef subtidal zone (Recife de Fora Municipal Marine Park, Porto Seguro, Bahia, Brazil), using artificial substrate units (ASUs), were exposed to a control pH (ambient seawater) and to three levels of seawater acidification (pH reductions of 0.3, 0.6 and 0.9 units below ambient) and collected after 15 and 30 days. The samples were fixed, washed in geological sieves (0.5 and 0.044 mm) and Nematofauna was identified to genus level with the aid of an optical microscope. Sixty genera distributed in 7 orders and 25 families were identified. The results showed that the community structure underwent significant differences for the time and treatment factors, but not for the interaction between them. The density was significantly different for the interaction between time and treatment factors. The richness of the genera suffered a reduction between treatments of pH 7.5 and 7.2. Only the genera Chromadora showed to be more sensitive to the experiment, which had a significant response to the time factor, with reduction of its density. For the trophic groups of the community significant differences were found for the two factors and for the interaction among them, for the Index of Trophic Diversity (ITD) the ANOVA results indicated that only the time factor was significant. The Maturity Index (MI) did not present significant results for any of the factors. The results presented showed that the effects can be complex, with positive and negative responses, due to the differential vulnerability within and between the generic groups of nematodes. They also showed that the functioning of the community can resist this type of impact, least on the scale of pH variation adopted in this experiment.

Full textThe pesticide Vertimec® 18EC is largely used to control pests in agriculture acting as insecticide, nematicide and acaricide. Although applied in agricultural lands it can reach the aquatic systems via surface runoff and affect many non-target species. A field experiment simulating the runoff over a field plot contaminated which consisted of two 6 m apart agricultural plots, one non-contaminated, acting as control, and the other contaminated with 0.125 L/\'M POT.2\' of Vertimec using a backpack sprayer. Runoff samples were collected downstream the plots. One fraction was used for physical and chemical analysis and laboratory acute toxicity tests and the remaining sample was inoculated in 12 cylindrical chambers, immersed in a water tank filled with Lobo Reservoir water, in a nearby constructed mesocosm. Three species of freshwater invertebrates were used as test-organisms in this study: Chironomus sancticaroli (Insecta, Diptera), Hydra viridissima (Cnidaria, Hydridae) and Girardia tigrina (Plathyelminthes, Turbellaria). The values of LC50 96 h for Vertimec® 18EC were: 0.14 mL/L (2.52 mg/L of abamectin) for H. viridissima, 0.028 mL/L (494 ug/L of abamectin) for G. tigrina and 0.54 \'10 POT.-5\' mL/L (97 ng/L of abamectin) para C. sancticaroli. These results indicate that C. sancticaroli has a much higher sensitivity to this pesticide than the other species tested. In the experiments in mesocosms it was found that in the highest concentration tested, the length and width of the body and cephalic capsules of the larvae in the contaminated runoff were smaller than those of the larvae from both, the control and non-contaminated runoff, evidencing that the chronic exposure to the Vertimec contaminated runoff affected adversely the growth of C. sancticaroli larvae. In addition some larvae in the contaminated mesocosm had mentum deformities (4.2%). The analyses of the whole community in the mesocosms at the end of the experiment showed that in the treatment with direct application of Vertimec, there were 100% mortality of all C. sancticaroli inoculated larvae, and almost 80% decrease in the richness of taxa and in the total density of benthic organisms when compared with the community in the control. No taxa belonging to the Class Insecta were recorded in the contaminated treatment corroborating the strong toxicity of this insecticide. From all results obtained we conclude that Vertimec® 18EC is highly toxic to benthic macro-invertebrates community and that aquatic ecosystems contaminated by agricultural runoff with this pesticide will be adversely affected.

Full textThe general aim of this work was to evaluate the distribution and the toxic effects of the metals Cr and Cu on lenthic aquatic ecosystems, using systems of different complexity and organization levels. The systems used for Cr and Cu toxicity evaluations were: a) single-specific tests with Selenastrum capricornutum (microalgae), Daphnia similis e Ceriodaphnia dubia (Cladocera), Chironomus xanthus (Diptera, Chironomidae), Oreochromis niloticus (fish) and Pistia stratiotes (macrophyte); b) microcosms experiments (multi- specific tests) with the Lobos reservoir natural communities; c) mesocosms experiments, with natural water, sediment, plankton, benthics, fishes and macrophytes from Lobos reservoir. In the toxicity tests, all the species were more sensitive to Cu than to Cr, and the sensitiviness sequence was D. similis> C. dubia> S. capricornutum> C. xanthus > P. stratiotes > O. niloticus. In the microcosms and mesocosms experiments, the test-concentrations were the maximum value allowed by the CONAMA Resolution nº 20/1986 to Cr6+ and Cu2+ to Class 2 water bodies (50 µg.L-1 and 20 µg.L-1, respectively). In all experiments the chlorophyll concentration was significantly reduced after the metal addition. The effects on the Zooplankton density and richness were stronger to Cr than to Cu; however Cladocera was more sensitive to Cu. Chromium caused higher inhibition in primary production in April/ 2002, but in November/ December 2002 the primary production suffered higher inhibition by Cu addition. Both studied metals showed significant effects on several water variables, as dissolved oxygen, ammonium, phosphate forms distribution, chlorophyll and suspended material, being the Cr effects stronger than the Cu effects, in relation to the number of affected variables and the system restoration time. The sediments didnt show alterations after the metal addition. Chromium and Cu bioaccumulation was observed by plankton, benthic invertebrates, macrophytes and fishes. The toxicity of the studied metals was reduced by the fish and macrophyte inclusion, mainly to Cu. Although the concentration of Cr and Cu were low, toxic effects were observed on both biotic and abiotic system compartments. The results obtained in this work may be useful as subsidy to evaluation of the maximum value allowed by the CONAMA Resolution nº 20/1986 to the studied metals.

Full textAgricultural activities, mainly monocultures, require large use of inputs. The constant application of agrochemicals, as herbicides, pesticides and fungicides, has promoted impacts on water resources and biota at the center, especially on non-target organisms such substances. This study aimed to evaluate the effects of fungicide Pyrimethanil in benthic macroinvertebrate community through environmental monitoring experimental units of field (mesocosms) and laboratory ecotoxicological tests with individuals of Chironomus sancticaroli. The mesocosms were made using six tanks with maximum volume equivalent to 1500 liters. The contamination of the tanks with Pyrimethanil was performed by spraying of water on the surface by applying a fungicide concentration equivalent to 0,1 mg/L. Thus, the mesocosms were divided into three contaminated replicas and three controls replicas. The monitoring and sampling of water and benthic macroinvertebrates were performed on a monthly basis during the period of one year. The fungicide Pyrimethanil does not cause significant changes in monitored variables. Similarly, the community structure of benthic macroinvertebrates were similar characteristics between the contaminated and control mesocosms. However, during the monitoring, the mesocosms controls had significantly higher values in the abundance of individuals and total number of taxa compared to the values observed in the mesocosms contaminated with Pyrimethanil.

Full textPesticides are chemical products applied to environment in order to control species which cause harm to agriculture. However, these chemicals can reach non-target species when flushed into aquatic ecosystems and even bring grave diseases to human health. Amongst many, Vertimec® stands out in a range of pesticides, being utilized in numerous agricultures, including potatoes and strawberries, which constitute the income of many farmers. Nevertheless, despite its intensive use, there is still lack of research and study on its potential risks on terrestrial and aquatic biota. In this context, we sought to evaluate the effects of the application of Vertimec® on phytoplankton, through laboratorial study (unialgal bioassay, with Pseudokircheneriella subcapitata) and in situ (composition and density, in mesocosms) starting from the simulation of soil contamination with Vertimec® and subsequent flushing into the body of water, making use of the runoff water in unialgal bioassay; the addition of runoff water from mesocosms in four treatments (control, contaminated runoff, non-contaminated and direct addition of contaminant), evaluating the effects on the community structure and unialgal bioassay with Abamectin, main Vertimec®s active principle. The results obtained show that the runoff effects on the cellular density of P. subcapitata will not occur according the product used but due to the high turbidity of the samples. At the tests with water at the mesocosms, the treatments which received runoff motivated the growing of P. subcapitata, indicating the nutrient-contributing effect to the environment of the culture. At the analysis of the phytoplanktonic community at the mesocosms, alterations on the physical and chemical characteristics of the water were observed (pH, dissolved oxygen, turbidity, conductivity and nutrients) featuring effects of runoff (with or without Vertimec®) or the direct addition of the contaminant, which implicated chances in the density and composition of the phytoplankton (such as the reduction of Bacillariophyta, increase of Chlorophyceae and, along with these , a larger contribution to the species Monoraphidium minutum). Despite acknowledging the effects of Vertimec® on phytoplankton, though in situ studies, the results from Abamectin do not show toxicity to the algae P.subcapitata, demonstrating the presence of other contaminants in the marketable product.

Full textOs estudos de avaliação de risco ecológico consistem em avaliar os riscos ecológicos ocasionados pelas diversas atividades antropogênicas a um determinado sistema. Essa abordagem de integração reporta a estimativa dos efeitos de risco adverso através dos níveis de organização biológica potencialmente expostos a pertubação, incluindo assim uma melhor compreensão da complexidade dos ecossistemas. É bem conhecido que os pesticidas possuem efeitos nocivos ao meio ambiente, contribuindo para a perda de biodiversidade e mudanças nos níveis tróficos. A partir dessa análise, o objetivo geral desse estudo foi uma avaliação de risco ecológico em cenários de contaminação por pesticidas em relação aos compartimentos terrestres e aquáticos. Para tanto, foram avaliados os efeitos diretos e indiretos sobre as respostas individuais para diferentes níveis de organização biológica e para as interações multitróficas através de modelos ecossistêmicos. Assim, foram analisados os impactos ambientais em relação as perdas e mudanças das funções e serviços dos ecossistemas. Para esse propósito, foram desenvolvidos cenários de risco em relação as rotas de exposição do antiparasitário Ivermectin para a minhoca Eisenia fetida em relação a testes de reprodução, através da via dermal (solo) e oral (comida). Foi construída uma abordagem experimental para caracterizar os efeitos do fungicida Scala® (Pyrimethanil), comparando a aplicação através de pulverização por spray com a aplicação homogênea no solo em um sistema terrestre multiespécies. Experimentos foram realizados para reportar os efeitos do fungicida Mythos® (Pyrimethanil) em plantas terrestres alvo, seguidos por teste com elutriato com organismos de água doce não-alvo e testes de fuga com invertebrados terrestres não-alvo e uma quantificação dos serviços ecossistêmicos. Foi realizada uma avaliação de risco holística do fungicida pyrimethanil com respostas dos organismos terrestres e aquáticos e das interações tróficas através dos modelos ecossistêmicos e complementados com respostas individuais. Os resultados obtidos sugerem que os parâmetros de reprodução para as minhocas foram afetados com o aumento das concentrações de ivermectina com diferenças estatísticas significativas entre as rotas de exposição a contaminação. O fungicida pyrimethanil mostrou efeitos adversos sobre os invertebrados terrestres para as aplicações do pesticida e para a distribuição espacial, sendo as preferências de habitat e habilidade de forageio direta ou indiretamente afetadas pela toxicidade do fungicida. Os possíveis impactos do runoff e lixiviação nos corpos de água e solos adjacentes mostram mudanças na estrutura da comunidade com mudanças e perdas nos serviços ecossistêmicos de provisão, regulação e suporte. A avaliação de risco holística mostrou os impactos e efeitos adversos sobre os organismos terrestres e aquáticos, ecossistemas e processos nos diferentes cenários de simulação. Ao analisar os dados obtidos é possível concluir que os experimentos realizados permeiam os múltiplos aspectos da contaminação por pesticidas, mostrando respostas de indivíduos a ecossistemas através das rotas de exposição da contaminação, interações multitróficas a partir dos experimentos de modelos ecossistêmicos, respostas individuais, comportamentais e comparativas com os sistemas terrestres e aquáticos em avaliações de risco ecológico. Portanto, esse estudo se apresenta como um importante registro dos efeitos deletérios e das respostas dos impactos por pesticidas, levando a possíveis perdas e mudanças das funções e serviços ecossistêmicos em áreas com distúrbios.

Full textIn-situ mesocosms experiments allow the extrapolation of laboratory data to the field with high reliability. In the present study, nine hexagonal PVC mesocosms with 2 m height and 4.5 to 5.1 m3 volume were installed in contact with the sediment near the Lobo reservoir dam (22º15\'S e 47º49\'W) in february of 2002. In accordance with the National Environmental Council (CONAMA) 20/86 resolution for Class 2 water bodies, the maximum allowed concentrations of copper (0,02 mg/L) and chromium (0,5 mg/L) were added to the mesocosms (triplicate), and three other ones were used as controls. The main purpose of this study was to evaluate the possible changes in the sediment environment, particularly the enrichment and induction of toxicity, by the contamination of these metals. The sediment was sampled by means of Eckman-Birge and core samplers on the 0 (before the contamination), 10th, 20th and 30th days (end of the experiment). Afterwards, physical and chemical analyses, benthic macrofauna characterization and several toxicity assays were conducted with the samples. In order to better evaluate these results, the sediments quality triad was considered. A discrete increase in the total concentration of copper and chromium was observed in the sediments of the contaminated mesocosms when compared to the controls, as well as a reduction in the abundance of benthic organisms and toxic effects over the organisms tested with these sediments. The triad responses were essential for quality characterization of the control mesocosms sediments in comparison with the contaminated ones.
