Повний текст джерелаBiological communities change in time and space following driving pressures from differences in habitat structure and resource availability. Understanding the ecological role and interactions within aquatic community is essential for any management action trying to improve water quality by interferences in lake food web, ecosystem dynamics and modeling. The present study was carried out in two freshwater systems in Southern Brazil: an irrigated rice field and in a large shallow system, Mangueira Lake. The goal of this study in temporary wetlands was to evaluate the plankton and fish dynamics during a productive cycle. Our results evidenced a temporal gradient by nutrients availability in the temporary wetland studied. However, the limnological variables did not display any horizontal pattern among sampling stations. Linear regression showed a positive relationship between chlorophyll a and nutrients, zooplankton biomass and copepod biomass. In contrast, fish biomass and planktivorous fish biomass were inversely related to chlorophyll a. Statistically significant relationships between DOC with nutrients, plankton and fish biomass were also identified during the rice production cycle. In Mangueira Lake, a shallow system (zmed 3m) and 90 km long, the goal was to evaluate the spatial and temporal distribution of plankton and fish biomass as a function of the presence of the emergent macrophytes Zizaniopsis bonariensis. We also analyzed the existence of longitudinal gradient in lake and the food web structure in system. The PCA and RDA analyses showed the temporal (seasonal) and spatial (North/South) gradient during the study. Analysis of similarity (ANOSIM) applied to environmental variables showed significant differences between sampling sites (North and South). Secchi transparency, DOC and chlorophyll a were significantly different in North and South sampling sites. ANOVA results showed that season effects are stronger in the Northern sampling site. Concerning the community structure in the Mangueira Lake, bacterioplankton biomass, chlorophyll a, zooplankton biomass and fish captures were different seasonally after extracting the habitat structure effect, while in the Southern sampling site only chlorophyll a presented a seasonal significant variation. Habitat structure (by Z. bonariensis stands and open water samples) induced significant differences in chlorophyll a both in North and South samples after extracting seasonal effect. Fish captures do also responded to habitat structure in the North, after extracting the season effect. Analysis of similarity (ANOSIM) applied to fish community also showed significant differences between North and South, although no significant differences between vegetated and open water zones was observed. Fish biomass, number of captures, and richness were different between sampling sites. Based on the δ13C and δ15N ratios and analysis of stomach content of fish species, we provide also a description of food web structure, trophic positions of fish species and primary producers of system. Analysis of nitrogen isotope ratios yielded two fish trophic levels in Mangueira Lake. Emergent macrophytes and periphyton were important carbon source that sustain the food web structure of the system. Cluster analysis of δ13C and δ15N values and stomach content yielded a perfect phylogenetic arrangement of species. This result reflects that major feeding niches are shared by taxonomically related species. The feeding dynamics of the dominant fish species, Oligosarcus jenynsii was analysed by using analyses of stomach contents and stable isotopes signature. Seasonal and ontogenetic change in the feeding biology of O. jenynsii was identified, showing the high feeding plasticity, in addition to an opportunistic strategy of this generalist carnivore species. This study allows identifying a large spatial heterogeneity and clear longitudinal gradient both in biotic and abiotic factors, reflecting fish and plankton distribution and abundance. The evaluated parameters are intended to feed a mathematical model for the Mangueira Lake, looking for predictable scenarios from natural and anthropogenic stressors.

Visto que os componentes abióticos formam a fonte de recursos basais, a abordagem deste trabalho consiste na avaliação dos efeitos da entrada de nutrientes alóctones em modelos estratégicos que descrevem a dinâmica de redes e cadeias tróficas, concentrando-se na determinação das características das populações de equilíbrio e das dinâmicas das espécies com diferentes respostas funcionais. Modelos estratégicos que contêm informações acerca do comportamento de populações interativas frente à entrada de nutrientes são uma base importante no delineamento de fenômenos gerais que podem ocorrer dentro da dinâmica de comunidades.

Recent studies demonstrated the efficacy of mangrove retaining nutrients and, in particular, the ability of the mineral component of the buffer in its high soil phosphorus levels. In general, the mangroves have been considered as important sinks of nutrients due to its high capacity purification of effluents. However, depending on the geochemical conditions exist, these soils can act as a source of phosphorus to other environments and / or coastal waters. Given that the geochemical behavior of phosphorus and its role in eutrophication of water bodies, is best measured by the behavior of its different fractions, this paper aims at a fractionation of the different forms of phosphorus in wetlands impacted by different effluent. The objective of this project is to study three areas in order to assess how activities impacting interfere in the process of nutrient cycling (with special emphasis on the dynamics of phosphorus forms) and, as the marsh supports the stress caused by these activities. Also, if you evaluate the potential for eutrophication of each human activities. Taking into consideration the impact that these environments suffer as a result of separate activities, were established the following areas of study: a marsh impacted by effluents from shrimp, a marsh impacted by effluents, and a control area located in a preserved area that still finds is little affected by human impacts. The samples were determined pH, Eh, salinity, grain size and the total content of C and P. In addition, extraction was performed sequentially phosphorus which allows differentiation of fractions 7: P exchangeable (NaClP), P associated with iron oxides (Fe-P); organic P (AH-P), the bound phosphorus hydroxides Al (Al-P), P associated with compounds of calcium (Ca-P); phosphorus associated refracting matter (P-RES) and unreacted phosphorus (P-NR). The results indicate that the discharge of effluents in mangrove increases the amount of phosphorus in these environments, especially in organic form, the phosphorus bound to carbonate is the major inorganic fraction in these environments.
Estudos recentes demonstram a eficácia do manguezal em reter nutrientes e, em especial, a capacidade dos componentes minerais do seu solo em tamponar elevados teores de fósforo. Em geral, os solos dos manguezais têm sido considerados como importantes sumidouros de nutrientes devido a sua grande capacidade de depuração de efluentes. Entretanto, dependendo das condições geoquímicas existentes, esses solos podem funcionar como fonte de fósforo para outros ambientes e/ou para as águas costeiras. Tendo em vista que o comportamento geoquímico do fósforo, bem como seu papel na eutrofização dos corpos d'água, é melhor avaliado através do comportamento de suas diferentes frações, o presente trabalho visa realizar um fracionamento das diferentes formas de fósforo em manguezais impactados por distintos efluentes. O objetivo da presente dissertação é estudar três áreas a fim de se avaliar como as atividades impactantes interferem no processo de ciclagem de nutrientes (com especial ênfase na dinâmica das formas de fósforo) e, como o manguezal suporta o estresse ocasionado por estas atividades. Além disso, se avaliará o potencial de eutrofização de cada uma das atividades antrópicas. Levando-se em consideração os impactos que esses ambientes sofrem em consequência de distintas atividades, foram estabelecidas as seguintes áreas de estudo: um manguezal impactado por efluentes de carcinicultura; um manguezal impactado por efluentes urbanos; e uma área controle localizada em uma área preservada que ainda encontra-se pouco afetada por impactos antrópicos. Nas amostras foram determinados pH, Eh, salinidade, granulometria e teores totais de C e P. Além disso, foi realizada a extração seqüencial de fósforo que permite a diferenciação de 7 frações: P trocável (NaCl-P); P associado a óxidos de Fe (FeP); P orgânico (AH-P); fósforo ligado a hidróxidos de Al (Al-P); P associado a compostos de cálcio (Ca-P); fósforo associado à matéria orgânica refratária (P-RES) e fósforo não reativo (P-NR). Os resultados obtidos indicam que o descarte de efluentes nos manguezais aumenta a quantidade de fósforo nesses ambientes, principalmente nas formas orgânicas; o fósforo ligado aos compostos de cálcio é a principal fração inorgânica nesses ambientes. Palavras-chave: ciclagem de nutrientes; extração sequencial; carcinicultura; efluente domiciliar.

Повний текст джерелаA Floresta Atlântica do Nordeste do Brasil contém milhares de fragmentos de florestas em diferentes estágios de regeneração, alguns se recuperando de campos agrícolas abandonados, enquanto outros se recuperam de distúrbios crônicos como incêndio, extração de madeira e caça furtiva. Alguns desses fragmentos ficaram protegidos por várias razões: responsabilidade corporativa, cumprimento do código florestal, preservação da biodiversidade, entre outros. Embora estes fragmentos estejam longe de ter a mesma riqueza de espécies vegetais e animais, podem desempenhar importantes serviços ecossistêmicos, como proteção de corpos d\'água, reservatório de importantes nutrientes e carbono. Isso é especialmente importante se considerarmos que há iniciativas globais como o REDD+ que visam avaliar florestas secundárias e de recuperação como importantes reservatórios de carbono (C). Por outro lado, a gestão e preservação destes fragmentos dependem de um conhecimento sólido sobre a sua estrutura e ciclo de nutrientes. Há uma literatura relativamente rica sobre a perda de biodiversidade nestes fragmentos florestais do Nordeste. No entanto, muito menos está disponível sobre a estrutura e o funcionamento destes fragmentos. Este trabalho pretende contribuir para o preenchimento desta lacuna, fornecendo informações científicas sólidas sobre quatro áreas florestais e uma floresta secundária, onde foi implantado um programa de restauração no Estado de Alagoas, Nordeste do Brasil. Após uma breve introdução, o capítulo um discute a estrutura desses fragmentos através de um inventário florestal completo, onde a densidade indivíduos, sua altura e diâmetro à altura do peito (DAP) foram medidos para cada árvore com DAP >= 10 cm. Com esses dados alométricos, estimamos a área basal e a biomassa viva acima do solo (AGLB), comparando esses atributos com outras estimativas disponíveis na literatura. No capítulo dois, investigamos a distribuição de nutrientes nos fragmentos florestais, onde medimos a concentração foliar de C, nitrogênio (N) e fósforo (P). Ao mesmo tempo, medimos durante um ano a massa da serapilheira em cada fragmento e seu teor de nutrientes. Com essas informações pudemos estabelecer como essas áreas ciclam seus principais nutrientes limitantes e C. Finalmente, no último capítulo abordamos a partição dos estoques de C e nutrientes, acima e abaixo do solo, com o objetivo de avaliar a importância dos pools de C e nutrientes nos fragmentos de floresta e entender qual o papel desses fragmentos em um mundo que necessita urgentemente estocar C em um reservatório sustentável.

Повний текст джерелаO consórcio entre milho (Zea mays L) e espécies de Brachiaria spp. (syn. Urochloa spp.) desempenha importante função no manejo da agricultura tropical, produzir resíduos ou forragem em áreas intensivamente cultivadas. Apesar de estudos anteriores fornecerem valiosas informações sobre efeitos do consórcio sobre o manejo do solo e produção de biomassa, um melhor entendimento de como este sistema de cultivo afeta a dinâmica de nutrientes (exógenos ou endógeno) é necessário. Dois experimentos foram conduzidos durante a safra e segunda safra. No primeiro, os monocultivos de milho e braquiária (Brachiaria brizantha cv. Marandu) foram comparados com dois padrões de consórcio, direcionado a produção de resíduos ou forragem, com simulação do pastejo animal. Biomassa, acúmulo de nitrogênio (N), N- fertilizante e balanço de N foram avaliados. As variáveis respostas praticamente não foram afetadas pelos sistemas de cultivos durante o período de coexistência. Após a colheita do milho, os sistemas consórciados acumularam mais biomassa (0,6 -11 Mg ha-1) e N (12-318 kg ha-1) comparado ao pousio precedido pelo monocultivo de milho, apesar destes incrementos afetarem apenas o acúmulos totais (pré+pós-colheita) do cultivo de safra. A recuperação do N-fertilizante foi semelhante entre os sitemas de cultivo. Quando o consórcio objetivou a implantação de pasto, o pastejo simulado após a colheita do milho influênciou o balanço de N, com deficit de aproximadamente -221 kg ha-1.O segundo experimento foi conduzido para investigar a influência das espécies de Brachiaria sobre o particionamento de nutrientes no milho e a ciclagem pós-colheita de grãos. Produção de biomassa, quantidades de N, fósforo (P) e postássio (K) acumuladas foram avaliadas no monocultivo de milho e em três espécies de Brachiaria spp. (B. Brizantha cv Marandu, B. ruziziensis, and B. hibrido cultivar Mulato II, Convert HD 36) em consórcio com milho. Biomassa e acúmulo de nutrientes não foram afetados no consórcio do milho com as espécies de Brachiaria. Após a colheita do milho, o acúmulo de biomassa e nutrientes das espéceis de braquiária classificadas em ordem decrescente foram: B. brizantha > B. ruziziensis > B. convert. Comparado ao monocultivo de milho, o consórcio aumentou a biomassa total (milho+braquiária) e o acúmulo de nutrientes apenas quando cultivado na safra. Entre os 6 locais/anos, os benefícios do consórcio ocorreu após acolheita do milho, especialmente para o cultivo de safra. O milho consorciado com espécies de Brachiaria não afetou a recuperação do N-fertilizante nem sua distribuição nos componentes do sistema solo-planta. Entretanto, o consórcio proporcionou maior acúmulo de biomassa após a colheita do milho se comparado ao pousio precedido pelo monocultivo de milho, aumentando a porção de nutrientes alocados no compartimento planta do sistema. Nossos resultados sugerem que a integração entre atividades de lavoura e pastejo aumenta a demanda por N do sistema de produção. O consórcio entre milho e Brachiaria brizantha cv Marandu no cultivo de safra foi a melhor estratégia para aumentar a produção de biomassa e a ciclagem de nutrientes no sistema de produção do milho.
