Resumo: Os metais traço são utilizados na indústria e na agricultura e podem estar presentes em efluentes de mineração e esgoto. Assim, esses elementos atingem o ambiente e podem ser prejudiciais aos organismos, meio ambiente e às pessoas. Um monitoramento representativo é essencial para a gestão dos recursos hídricos e consequente prevenção à poluição. Monitoramentos convencionais da água algumas vezes podem não revelar a real condição do ambiente. Isto acontece devido às condições de lançamento e chegada dos poluentes ao sistema, à tecnologia disponível para quantificar a concentração e devido às características da própria substância monitorada. No caso dos metais traço, estes têm uma atração maior por outras partículas (sólidos suspensos, solo, sedimento, carbono orgânico dissolvido), as quais sedimentam, não permanecendo na coluna d'água. Outro fator a ser considerado é que as fontes de metais traço são geralmente intermitentes e as coletas são não contínuas. Além disto, os limites de detecção são altos e não detectam tais elementos na água. Desta forma, o biofilme é uma técnica alternativa de monitoramento, pois analisa o nível de contaminação em um intervalo de tempo. Para este estudo foram construídos dois amostradores. Amostras de biofilme, água e sedimento foram coletadas ao longo de oito meses para dois pontos de monitoramento, um na bacia do rio Barigüi e outro na bacia do rio Miringuava. Parâmetros de qualidade da água, granulometria e conteúdo de metais traço foram estimados. Os resultados mostram que o biofilme identificou os metais traço em praticamente todas as campanhas, enquanto que para as amostras de água isto não aconteceu. As amostras de sedimento representaram a poluição, porém não foi possível determinar o tempo da contaminação pelo método de coleta utilizado. O biofilme representou as diferenças no uso e ocupação do solo, representando poluição consistente com cada bacia hidrográfica. Palavras-chave: biofilme, metais traço, monitoramento, rio Miringuava, rio Barigüi.
Abstract: Trace metals are used in industries and agriculture and can be present in mining and sewer effluents. In such context, these elements can enter the environment and be very harmful to organisms, environment and people. A representative monitoring is essential for water resources management and, consequently, pollution prevention. Conventional water monitoring do not always show real environment condition. That happens because of effluent release conditions, pollution arrival system conditions, available technology to identify element concentrations and monitoring substance characteristics. Specifically for trace elements, they tend to adhere to other particles (suspended matter, soil, sediment, DOC) and deposit in riverbed. Other factor is that trace metal sources are usually from intermittent discharges and collections are not continuous. Besides that, usual techniques have high quantification limit and do not identify these elements in water. Thus, biofilm is an alternative monitoring technique for trace metals evaluation since it analyses contamination level in a time space. For this study, two biofilm samplers were constructed. Biofilm, water and sediment samples were collected for an eight month period in two monitoring sites, Barigüi and Miringuava watershed. Water quality parameters, granulometry, and trace metals content were estimated. Results showed that biofilm identified metals in almost every campaign, while water samples did not. On the other hand, sediment samples represented pollution but it was not possible to determine the contamination time by the used collection method. Biofilm also represented differences in soil use and occupation, representing consistent pollution potential for each basin. Keywords: biofilm, trace metals, monitoring, Miringuava River, Barigüi River.

Resumo: Com a intensificação das transformações dos sistemas naturais pela atividade humana, o entendimento dos processos que afetam as comunidades e o funcionamento dos ecossistemas tornou-se um tema central para a ecologia contemporânea. As interações entre as espécies, bem como as interações entre as espécies e os componentes abióticos do meio ambiente, afetam tanto os padões de diversidade biológica como funções ecossistêmicas. Neste trabalho, buscou-se compreender o papel relativo das interações predador-presa e dos componentes abióticos sobre as propriedades das comunidades e funcionamento dos ecossistemas. No primeiro capítulo, investiguei o papel do tamanho do habitat sobre os efeitos de predadores terrestres na estrutura de comunidades e funcionamento de ecossistemas adjacentes. O tamanho do habitat modera cascatas tróficas dentro de ecossistemas, deste modo, esperei que efeitos similares do tamanho do habitat poderiam afetar cascatas tróficas que ocorrem através dos limites dos ecossistemas. No segundo capítulo, explorei predições relacionadas a variação no formato de pirâmides tróficas de biomassa ao longo de gradientes ambientais (tamanho do habitat, concentração de detritos e produtividade). Além disso, investiguei a contribuição relativa dos efeitos de consumo direto e do risco de predação nas interações predador-presa como mecanismos estruturadores de pirâmides tróficas de biomassa. No terceiro capítulo, tive como objetivo investigar os efeitos de dois extremos de um gradiente ambiental e os efeitos de predadores sobre os componentes da diversidade de presas detritívoras (i.e., diversidade funcional, filogenética e taxonômica). Além disso, explorei o papel relativo do ambiente, dos predadores e dos componentes da diversidade sobre o funcionamento ecossistêmico (i.e., decomposição e fluxo de nitrogênio). Os resultados encontrados nos três capítulos demonstram que fatores abióticos são cruciais na determinação das propriedades das comunidades, interações predador-presa e, consequentemente, no funcionamento ecossistêmico. O papel relativo dos efeitos cascatas de predadores é altamente dependente das condições ambientais que medeiam as interações entre predadores e presas
Abstract: In the face of the increasing transformation of environmental conditions by human activity, understanding the processes that affect communities and ecosystem functioning has become fundamental goals in ecology. The interactions between coexisting species and, their interactions with the abiotic components of environment, affect the patterns of biological diversity and functions of ecosystems. In this study, I sought to understand the relative role of predator-prey interactions and of abiotic factors on the communities¿ properties and ecosystem functioning. In the first chapter, I investigated the role of habitat size in mediating the effects of terrestrial predators on the structure of communities and the functioning of adjacent ecosystems. Habitat size mediated trophic cascades within ecosystems; therefore, I expected that similar effects of habitat size affect cross-ecosystem trophic cascades. In the second chapter, I explored predictions related to the variation of trophic pyramids of biomass across environmental gradients (i.e., habitat size, detritus concentration and productivity). Furthermore, I investigated the relative contribution of consumptive and non-consumptive effects of predators on the shape of trophic pyramids of biomass. In the third chapter, I sought to investigate the effects of two extremes of an environmental gradient and the effects of predators on the components of detritivores diversity (i.e., functional, phylogenetic and taxonomic). Moreover, I explored the relative role of environment, predators and detritivore diversity components on the functioning of ecosystems (i.e., detritus processing and nitrogen flux). The results from this study demonstrated that abiotic factors are crucial determinants of community properties, predator-prey interactions and ecosystem functioning. The relative role of the predators cascading effects are strongly dependent on the environmental conditions which mediate the interactions between predators and prey

Pełny tekst źródłaWetlands exhibit high primary productivity and play a significant role in the global carbon cycle. Brackish and salt marshes co-occur in Southern California; yet, restoration designs often eliminate remnant brackish marshes, along with their ecosystem functions, without evaluation. Vegetation, soil organic matter, and carbon flux were compared between brackish and salt marsh habitats in the Huntington Beach Wetlands. Newland Brackish Marsh had more carbon aboveground in denser and taller vegetation than the other two marshes. Brookhurst Salt Marsh sediments had more organic matter than the other two marshes. CH4 emissions were negligible at all sites, and there were no differences in CO2 flux or aerobic and anaerobic microbial respiration among sites. Although these components of the carbon cycle were similar among sites in this project, such quantitative functional evaluations should be part of the restoration planning process.

Pełny tekst źródłaThe present study aims to provide a solid background for river-floodplain restoration based in the response of aquatic communities, to changes in hydrological connectivity, environmental factors and human pressure across the floodplain of a Mediterranean river.The lateral hydrological connectivity was found to be the key factor structuring the habitats and aquatic communities of the Middle Ebro floodplain, while turbidity, salinity and nutrient status were secondary drivers. These factors created a template for the aquatic community development that enabled predictions about the taxonomic and functional patterns in those aquatic communities more likely to occur under particular conditions. In the Middle Ebro River, there are very few possibilities of new wetlands creation, while the diversity and functionality of the remaining ones are threatened by the limited hydrological connectivity. The objective of floodplains restoration should thus consist in re-establishing a wide range of wetland types in accordance with the river-floodplain potential of sustainability.

Pełny tekst źródłaThe introduction of lake trout Salvelinus namaycush into Yellowstone Lake preceded the collapse of the native Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri population. As a system with a simple fish assemblage and several long-term data sets, Yellowstone Lake provided a unique opportunity to evaluate the ecology of a native salmonid in the presence of a non-native salmonid population undergoing suppression in a large natural lake. Diet data for Yellowstone cutthroat trout and lake trout were evaluated at varying densities to determine the effects of density on diet composition. Temporal diet shifts from 1996-1999 to 2011-2013 were likely caused by limitation of prey fish for lake trout. Diets, stable isotopes, and depth-related patterns in CPUE indicated lake trout > 300 mm consumed primarily amphipods, making them trophically similar to Yellowstone cutthroat trout from during 2011-2013. A lake trout removal program was initiated during 1995 to reduce predation on Yellowstone cutthroat trout. Abundance and fishing mortality were estimated for lake trout from 1998 through 2013 and Yellowstone cutthroat trout from 1986 through 2013. Density-dependence was evaluated by examining individual growth, weight, maturity, and pre-recruit survival as a function of abundance. In addition, a simulation model was developed for the lake trout-Yellowstone cutthroat trout system to determine the probability of Yellowstone cutthroat trout abundance persisting at performance metrics given potential reductions in lake trout abundance. Estimates of Yellowstone cutthroat trout abundance varied 5-fold and lake trout abundance varied 6-fold. Yellowstone cutthroat trout weight and pre-recruit survival decreased with increasing Yellowstone cutthroat trout abundance; however, individual growth and maturity were not related to abundance. Lake trout population metrics did not vary with lake trout abundance. Simulation model results were variable because of uncertainty in lake trout pre-recruit survival. Conservative estimates for required lake trout reductions were > 97% of 2013 abundance for a > 70% probability of Yellowstone cutthroat trout persistence at the performance metrics outlined in the Native Fish Conservation Plan. Lake trout removal will likely reduce lake trout abundance and result in Yellowstone cutthroat trout recovery if the amount of fishing effort exerted in 2013 is maintained for at least 15 years.

Pełny tekst źródłaWith the main aim of verifying whether Daphnia magna is sufficient for the evaluation of the environmental risk of pesticides to aquatic ecosystems, toxicity values of 218 insecticides were analyzed. For each one the relative tolerance (Trel) value was calculated to compare the sensitivity of species from different taxonomic groups with that of D. magna. The taxonomic groups were grouped in arthropods, non-arthropod invertebrates, fish, algae/macrophytes and based on Trel values the species sensitivity distribution (SSD) were defined. For the arthropods the influence of the mode of action (MOA) on vulnerability to the insecticide was also analyzed. Still in the arthropods group, for each species, the class, order and family they belong to were identified. To check the necessity of inclusion of a second species studies of relationship were performed, between D. magna, Americamysis bahia and Chironomus riparius. As far as the SSD curves are concerned, for the different groups the most sensitive one was the arthropods group in both values of EC50 and NOEC. Taking into consideration MOA the group of neonicotinoids was the most sensitive one in EC50 case and the GABA – gated chloride channel antagonists in NOEC. The most sensitive taxonomical group was Mysida and it was the combination of Daphnia plus A. Bahia that generated the greater percentage of protection.
