Streszczenie:
George Evelyn Hutchinson is recognised as one of the best limnologists and ecologists of the 20th century, whose contributions have been key for the development of modern ecology and limnology. His most important contributions nclude, concepts, theories and classifications currently used such as, for example, the ecological niche concept, Hutchinson’s paradox and lake classifications. Hutchinson redefined the ecological niche concept based on previous ideas of Grinnell and Elton, suggesting that it should be considered as a hypervolume in the environmental space caused by the ultidimensional response of variables that determine the stability of populations. This new perception of the ecological niche has been fundamental for the development of other investigations in different fields of biology, in particular in ecology, evolution, and biogeography. Furthermore, Hutchinson’s treatise on limnology is considered as the most extensive compilation of limnology. Hutchinson aimed to answer why several species of phytoplankton that compete for the same resources can coexist in an aquatic ecosystem which is usually nutrient deficient (known as the Hutchinson’s paradox). The scientific advances promoted by Hutchinson have inspired many generations of biologists. George Evelyn Hutchinson es reconocido como uno de los mejores limnólogos y ecólogos del siglo XX, cuyas aportaciones han sido cruciales para el desarrollo de la ecología y limnología moderna. Sus más importantes contribuciones incluyen conceptos, teorías y clasificaciones vigentes en la actualidad como, por ejemplo, el concepto de nicho ecológico, la paradoja de Hutchinson y las clasificaciones de lagos. A partir de las ideas de Grinnell y Elton, Hutchinson sugirió que el concepto de nicho ecológico debía considerarse como un hipervolumen en el espacio ambiental originado por la respuesta multidimensional de las variables que determinan la estabilidad de las poblaciones. Esta nueva percepción del nicho ecológico ha sido fundamental para el desarrollo de otras investigaciones en diferentes campos de la biología, particularmente en la ecología, la evolución y la biogeografía. Por otro lado, el tratado de limnología realizado por Hutchinson es considerado como la recopilación más extensa de la limnología. Hutchinson intentó dar respuesta a por qué varias especies del fitoplancton que compiten por los mismos recursos pueden coexistir en un ecosistema acuático que por naturaleza suele ser deficiente en nutrientes (conocido como la paradoja de Hutchinson). Los avances científicos promovidos por Hutchinson han servido de fuente de inspiración a muchas generaciones de biólogos.

Este trabalho teve como objetivo comparar o comportamento limnológico no período de doze meses dos viveiros de piscicultura de engorda e pesque-pague em um estabele-cimento de pesque-pague localizado no município de Corumbataí. As saídas de campo foram realizadas mensalmente em um período de doze meses no período matutino. Quatro viveiros de pesque-pague e quatro viveiros de engorda foram analisados, nos quais os seguintes parâmetros foram medidos: oxigênio dissolvido, temperatura, pH, condutividade, turbidez. Além destes, a água foi coletada e armazenada em frascos plásticos para serem analisadas em laboratório: fósforo total e nitrogênio total Kjeldahl. Foram aplicados Analises de Componentes Principais (PCA) e ANOVA fatorial para os escores obtidos com a PCA. Pôde ser observada características discriminantes entre os viveiros de engorda e pesque-pague através da PCA, assim como a existência de diferença significativa (p<0,05) entre os períodos de verão e inverno e entre os viveiros de pesque-pague e engorda. Conclui-se que o diferente manejo empregado aos vivei-ros de engorda e pesque-pague nos períodos de verão e inverno principalmente com o fornecimento de ração tornam os viveiros de engorda ambientes mais eutrofizados, especialmente no verão

Streszczenie:
Levando-se em consideração a grande demanda por água e por fim a poluição emergente nos dias de hoje, o gerenciamento dos corpos hídricos deve ser algo constante, com o propósito preventivo e corretivo, sendo o objetivo deste trabalho a análise das condições ecotoxicológicas e limnológicas dos reservatórios Guarapiranga, Billings e Paiva Castro, na Região Metropolitana de São Paulo, que é abastecida por tais reservatórios. Foram realizadas duas coletas, sedo uma em Maio de 2011, na estação seca, e outra em Janeiro de 2012, na estação chuvosa. Em cada reservatório foram analisados cinco pontos próximos à captação de água pela SABESP. A água e sedimento foram avaliados quanto à toxicidade aguda e crônica através de bioensaios com os cladóceros Daphnia similis e Ceriodaphnia dubia para a água e D. similis e Chironomus xanthus para o sedimento. O tratamento dos dados ocorreu através dos testes de Dunnett\'s ou Steel\'s Many-one Hank e Kruskal-Wallis (fecundidade / sobrevivência) e Fisher Exact Test (mortalidade). Os parâmetros limnológicos analisados na água foram: pH, temperatura, condutividade elétrica, material em suspensão (orgânico e inorgânico), sólidos totais, oxigênio dissolvido, DQO, DBO, nitrogênio total, nitrato, nitrito, amônio, fósforo total, ortofosfato e clorofila a. Os parâmetros físico-químicos do sedimento analisados foram: pH, temperatura, granulometria, teor de Matéria Orgânica e metais (Cd, Cu, Ni, Zn, Pb e Mn). O grau de associação entre as variáveis limnológicas da água, sedimento, e testes ecotoxicológicos, foi avaliado em teste não-paramétrico, através do Coeficiente de Correlação de Spearman. As mesmas variáveis também foram analisadas através da Análise dos Componentes Principais (ACP). O Índice de Estado Trófico mostrou serem os reservatórios Guarapiranga e Billings os mais eutrofizados dentre os corpos hídricos estudados. Conforme os parâmetros analisados na água, alguns parâmetros de certos pontos amostrais estiveram fora dos Padrões estabelecidos pela Resolução CONAMA nº 357/05. Houve influência das chuvas em relação aos parâmetros limnológicos da água, mas o mesmo não foi evidenciado em relação aos resultados dos testes ecotoxicológicos. No geral os dados sugerem ser o sedimento dos reservatórios com maior potencial tóxico do que a água. Os dados ainda sugerem um gradiente de toxicidade, começando pelo reservatório Billings, Guarapiranga e por último Paiva Castro, sendo este o menos tóxico. Houve uma possível correlação entre os metais encontrados no sedimento dos reservatórios mais eutrofizados e a toxicidade obtida nos testes ecotoxicológicos. Os dados sugerem que maiores esforços preventivos e corretivos devem ser alocados para os reservatórios mais eutrofizados e com maiores ocorrências de toxicidade, como é o caso de Guarapiranga e Billings, enquanto que no terceiro reservatório, Paiva Castro, o monitoramento e esforços preventivos serão satisfatórios, mantendo os padrões de qualidade de suas águas em relação aos parâmetros analisados neste trabalho.
Considering the great water demand and the increase pollution in the present-day, the management of the hydric bodies must be something constant, with the preventive and corrective purpose, being the objective of this work to analyze the ecotoxicological and limnological conditions of Guarapiranga, Billings and Paiva Castro reservoirs, in the Metropolitan Region of São Paulo, that\'s supplied by these reservoirs. It was made 2 collections, one in May 2011, in the dry season, and the other in January 2012, in the wet season. In each reservoir it was analyzed 5 points next to the water captation station by the SABESP. The water and sediment were analyzed as for acute and chronic toxicity through bioEssays with the cladocerans Daphnia similis and Ceriodaphnia dubia to the water and D. similis and Chironomus Xanthus to the sediment. The data treatment occurred through the Dunnett\'s or Steel\'s Many-one Hank and Kruskal-Wallis (fecundity/ survival) and Fisher Exact Test (mortality). The limnological water parameters analyzed were: pH, temperature, electrical conductivity, suspended solids (organic and inorganic), total solids, dissolved oxygen, COD, BOD, total nitrogen, nitrate, nitrite, ammonium, total phosphorus, orthophosphate and chlorophyll a. The physical-chemical analyzed parameters in sediment were: pH, temperature, granulometry, organic matter, and metals (Cd, Cu, Ni, Zn, Pb and Mn). The association level between the limnological variables in water, sediment, and ecotoxicological tests, was available in non-parametric tests, through the Spearman correlation coefficient. The same variables were analyzed through the Principal Component Analysis. The Trophic State Index show the Guarapiranga and Billings reservoir as the most eutrophicated between the hydric bodies studied. According to the analyzed parameters in the water, some parameters of certain points were out of the standards established by CONAMA Resolution nº 357/05. There was influence from the rain in relation to the limnological parameters from water, but the same standard was not evidenced in relation to the results from the ecotoxicological tests. In general, the data suggest being the reservoir sediments with more toxic potential than the water. The data still suggest a toxicity gradient, beginning in the Billings and Guarapiranga reservoir, and for last Paiva Castro, being this one the less toxic. There was one possible correlation between the metal found in the more eutrophicated reservoir sediment and the toxicity obtained in the ecotoxicological tests. The data suggest that greater preventive and corrective efforts must be allocated to the more eutrophicated reservoirs with more toxicity occurrences, as the case of Guarapiranga and Billings, while in the third reservoir, Paiva Castro, the monitoring and preventive efforts will be satisfactory, keeping the water quality standard in relation to the parameters analyzed in this work.

Estudos limnológicos em viveiros de piscicultura abordando as características físicas, químicas e biológicas são de extrema importância para a manutenção dos organismos aquáticos, pois caracterizam o ambiente de maneira completa, permitem compreender a dinâmica do sistema e aplicar manejo adequado no local, aumentando a produtividade e a qualidade da piscicultura. A comunidade planctônica é uma ferramenta fundamental para esta caracterização, sendo composta por organismos sensíveis às mudanças na qualidade da água que respondem através da diversidade e abundância de espécies. O principal objetivo deste trabalho foi classificar a qualidade da água de um viveiro de piscicultura (21°11'S e 48°18'W) localizado no Centro de Aquicultura da UNESP de Jaboticabal, SP, de acordo com a comunidade planctônica presente neste ecossistema e o Índice de Estado Trófico. Os resultados mostraram uma comunidade planctônica característica de ambiente eutrófico, com dominância dos gêneros: Thermocyclops, Brachionus, Keratella e Trichocerca (zooplâncton) e Anabaena, Aphanocapsa e Microcystis (fitoplâncton). O Índice de Estado Trófico corrobora os resultados obtidos através da análise da comunidade planctônica, classificando todos os pontos amostrados no viveiro como eutróficos (variando de 66 a 70). É possível concluir que o enriquecimento da coluna d'água é promovido pelo sistema de fluxo contínuo, que traz uma elevada carga para o viveiro estudado através do efluente dos viveiros e tanques localizados à montante deste, tornando as características limnológicas propícias para o desenvolvimento de espécies de Cyanobacteria potencialmente tóxicas tais como Microcystis aeroginosa e Pseudanabaena catenata, do grupo Cyanobacteria...
Limnological studies in fishpond considering physical, chemical and biological characteristics are of extreme importance for the maintenance of the aquatic organisms because such variable are essential to characterize the environment as a whole, permitting to amplify the understanding of the dynamics of the system and allowing the adoption of an adequate local management, increasing the productivity and quality of the commercial activity. An overlook in the planktonic community is a fundamental tool to complete such characterization because such community is composed by sensitive organism dependents upon the quality of the water. Any alteration in such condition may reflect in changes in the abundance and diversity of present species. The main objective of this study was classify the quality of the water of a fishpond located in the Aquiculture Center of the State University of São Paulo in Jaboticabal, SP - Brazil (21°11'S e 48°18'W) in relation to the planktonic community present in the system and the Trophic Status Index. The results showed a planktonic community typical of eutrophic environment with a dominance of the genera: Thermocyclops, Brachionus, Keratella and Trichocerca (zooplankton) and Anabaena, Aphanocapsa and Microcystis (phytoplankton). The Trophic Status Index corroborated with the results found for the planktonic community, classifying all sampled points in the fishpond as eutrophic (varying from 66 to 70). It is possible to conclude that the enrichment of the water column was promoted by the continuous influx in the fishpond, in which carries a higher load of effluents from nurseries and other fishpound located upstream. Such condition becomes the limnological characteristics favorable for the potentially propagation of toxic species as Microcystis aeroginosa and Pseudanabaena catenata from the Cyanobacteria group, calling the attention for an adequate management of the local, avoiding a booming of such ...

Abstract: The objective of this study was to evaluate the influence of limnological variables and current velocity on the development of Limnoperna fortunei and the recruitment of new individuals in areas with network tanks in the Canoas II Reservoir on the Paranapanema River. Monthly from August / 2016 to January / 2017 in the field measurements were made of: transparency, dissolved oxygen potential hydrogen, electrical conductivity and total dissolved solids. In addition, water was collected and stored in bottles to be analyzed in laboratory: total nitrogen, nitrite, nitrate, ammonia, total phosphorus, orthophosphate, calcium, alkalinity, hardness and chlorophyll a. Water current velocity measurements were obtained using a flow meter and an ADCP. Samples of larvae of L. fortunei were obtained using a suction pump and 40 μm plankton net. Crosswood substrates were made for counting and measuring the size of fixed larvae. Limnological variables were investigated through Principal Component Analysis (PCA). The comparison between the length of the individuals in the two areas evaluated and the current velocity measurement with the ADCP was done by means of Box Whisker Plot. The results of current velocity of the water with the flowmeter and of the relation between larval density in the water column and number of fixed individuals was done with the aid of graphs. Limnological variables may have influenced the development of L. fortunei, especially in TR2. It has not been proven that water ... (Complete abstract click electronic access below)

This thesis presents the results of contemporary limnological and palaeolimnological investigations of a series of crater lakes in order to reconstruct the palaeoenvironmental history of western Uganda, East Africa. The research examines questions of spatial and temporal heterogeneity of climate changes in the context of growing human impacts on the landscape over the last millennium. Sediment records from two lakes, Nyamogusingiri and Kyasanduka within the Queen Elizabeth National Park (QENP) were investigated to look at the long term records of climate and environmental change (spanning the last c. 1000 years). Five shorter cores across a land-use gradient were retrieved to assess the impact of human activity on the palaeoenvironmental record over the last ~150 years. High-resolution (sub-decadal), multiproxy analyses of lake sediment cores based on diatoms, bulk geochemistry (C/N and δ13C) and sedimentary variables (loss-on-ignition, magnetic properties and physical properties) provide independent lines of evidence that allow the reconstruction of past climate and environmental changes. This multiproxy approach provides a powerful means to reconstruct past environments, whilst the multi-lake approach assists in the identification and separation of local (e.g. catchment-scale modifications and groundwater influences) and regional effects (e.g. climatic changes). The results of a modern limnological survey of 24 lakes were used in conjunction with diatom surface sediment samples (and corresponding water chemistry) from 64 lakes across a natural conductivity gradient in western Uganda (reflecting a regional climatic gradient of effective moisture) to explore factors controlling diatom distribution. The relationships between water chemistry and diatom distributions were explored using canonical correspondence analysis (CCA) and partial CCA. Variance partitioning indicated that conductivity accounted for a significant and independent portion of this variation. A transfer function was developed for conductivity (r2jack = 0.74). Prediction errors, estimated using jack-knifing, are low for the conductivity model (0.256 log units). The final model was applied to the core sediment data.This study highlights the potential for diatom-based quantitative palaeoenvironmental reconstructions from the crater lakes in western Uganda. Sedimentary archives from the Ugandan crater lakes can provide high-resolution, annual to sub-decadal records of environmental change. Whilst all of the lakes studied here demonstrate an individualistic response to external (e.g. climatic) drivers, the broad patterns observed in Uganda and across East Africa suggest that the crater lakes are indeed sensitive to climatic perturbations such as a dry Mediaeval Warm Period (MWP; AD 1000-1200) and a relatively drier climate during the main phase of the Little Ice Age (LIA; c. AD 1500-1800); though lake levels in western Uganda do fluctuate, with a high stand c. AD 1575-1600). The general trends support the hypothesis of an east to west (wet to dry) gradient across East Africa during the LIA, however, the relationship breaks down and is more complex towards the end of the LIA (c. AD 1700-1750) when the inferred changes in lake levels at Nyamogusingiri and Kyasanduka are synchronous with changes observed at Lakes Naivasha (Kenya) and Victoria and diverge from local lake level records (from Edward, Kasenda and Wandakara). Significant changes in the lake ecosystems have occurred over the last 50-75 years, with major shifts in diatom assemblages to benthic-dominated systems and an inferred increase in nutrient levels. These changes are coincident with large sediment influx to the lakes, perhaps as a result of increasing human activity within many of the lake catchments.

Streszczenie:
This work should demonstrate the interest of a new concept to show the link between limnology and geopolitics. With the term of “limnic border”, we can demonstrate the difference between the zonal border in two dimensions, typical for geopolitics and the deep border, typical for limnology. The introduction will constitute a resume of the historic and epistemological evolution of the vision about border and natural lake and how geopolitical and limnology develop in different ways. We demonstrate the interest to associate these two views, with regard to a general approach associating “biophysical vision” and “anthropic vision”. With the definition of how we can think multiple separation about transboundary lake, we should demonstrate the accuracy and the interest of a new three-dimensional vision, “the limnic border”. We will demonstrate how we can show the accuracy of this new concept by a description of a cross methodology, included limnologic measures and survey.

The subject proposed in this article concerns the intersection of the hydrodynamics of lakes and ponds with the economic development of their territory. It will be a question of understanding the interactions between these water bodies and territorial actors evolving on these limnic territories. Different managements are therefore imposed on each of the parties present. These managements are organized according to the limnological mechanisms specific to each environment (ponds and lakes), their temporality, their spatiality, and their risks for the human activities integrated into these water bodies. We will focus in this article on water and sediment movements not yet studied to interact with local managements. These phenomena constitute a base on which the actors around these water bodies can rely to guide the measures used to protect their activities. The purpose of this article is to provide scientific insights for decision support to actors evolving in the federation of municipalities of the Great Lakes, in the Landes, in New-Aquitaine (France).

Agricultural production is one of the main sources of nitrogen and phosphorous inputs to the water bodies. Quantifying nutrient input from agriculture is needed both to develop effective environmental measures and to justify the technologies to be applied with due account for local natural and climatic conditions. Several related national studies have been conducted since 2015. Institute for Engineering and Environmental Problems in Agricultural Production (IEEP) methodology was used for this purpose. It determines the nitrogen and phosphorus content in the arable layer, including N and P amounts applied with mineral and organic fertilisers. Such factors as soil type and texture, the distance to the water bodies and the land use structure are used to estimate the nutrient input to the water bodies. In addition, the consistency of manure handling technologies with Best Available Techniques (BAT) principles is taken into account through introduction of relevant coefficients. Calculation results according to IEEP methodology were used in the follow-up general assessment of the nutrient load on the water bodies from different sources with the use of Institute of Limnology Load Model. Satisfactory correspondence between the assessment results and the values calculated using the monitoring data confirmed the adequacy of the above assessment procedure. Following its outcomes, the nutrient reduction potential of agricultural sources is approximately 10–20 %.

ABSTRACT Important syn-rift hydrocarbon discoveries in the Tertiary East African Rift and in the South Atlantic subsalt basins have in recent years promoted renewed interest in the variability of source and reservoir rock facies in continental rifts. This talk considers several important new observations and developments in our understanding of the sedimentary evolution of lacustrine rift basins. Offshore subsalt basins in the South Atlantic demonstrate the importance of lacustrine carbonates, and especially microbialites, as reservoir facies in extensional systems. The role of rift-related magmatism is significant in these basins, both as drivers of hydrothermal systems around and within rift lakes, and as a source of solutes that facilitate carbonate accumulations. In the Tertiary East African Rift, substantial new hydrocarbon resources have been identified, including onshore siliciclastic reservoirs in remarkably young and shallow parts of the sedimentary section in the Albertine Graben. Rollover anticlines and fault-related folds serve as important structures for several new fields in the East African Rift, but larger structures affiliated with accommodation zones, in many instances located far offshore in the modern lakes, remain untested. Lacustrine source rocks that accumulated in stratified lake basins are the source of the oil and gas in these systems, however there is still much to be learned about their spatial and temporal variability. There is observed considerable variation in the character of organic matter on the floors of modern African lake basins, even adjacent ones. A number of factors likely govern the amount of total organic carbon preserved within the basins. These include 1) primary productivity; 2) degree of siliciclastic dilution, which is controlled in part by offshore slopes and the extent of onshore catchments, and 3) physical limnology, controlled by climate and basin-scale physiography, and the fetch-depth ratio of the lakes, which determines the likelihood of water column stratification. Scientific drilling in the African Rift lake basins is providing considerable information on the high temporal hydroclimate variability of the region, especially in the later Tertiary and Quaternary, which substantially controls basin lithofacies.

Streszczenie:
Avec l'augmentation attendue des activités minières dans les régions nordiques du Canada en raison de la demande mondiale de minéraux critiques, il est impératif de concevoir des méthodes nouvelles et fiables pour identifier les lacs qui peuvent être situés au-dessus des sections de sol non gelées (c.-à-d. les taliks) dans les environnements de pergélisol continu. Lorsque les taliks pénètrent complètement le pergélisol, ils peuvent permettre des interactions entre les eaux de surface et les eaux souterraines sous le pergélisol, ce qui présente des défis importants pour les opérations minières. Ce rapport fournit des données de référence détaillées sur la température de l'eau, la conductivité et parfois des mesures de pH pour les lacs près de Rankin Inlet, au Nunavut, effectuées en avril et en septembre 2023. Cet ensemble de données alimentera nos modèles thermiques et géophysiques pour l'identification des taliks et les modèles conceptuels cryo-hydrogéologiques pour la simulation de l'écoulement hydrogéologique souterrain dans les régions de pergélisol continu. Nos résultats révèlent notamment qu'en avril, les températures de la colonne d'eau dans les bassins lentiques sélectionnés variaient de 0,1 à 2°C directement sous la couverture de glace et de 1,7 à 3,5°C à l'interface eau-sédiment. Inversement, en septembre, la colonne d'eau des bassins étudiés était isotherme. Ces profils de température suggèrent que les lacs étudiés présentent des caractéristiques indiquant des bassins polymictiques froids, la stratification hivernale étant plus prononcée avec l'augmentation de la profondeur du bassin. En outre, nos mesures de conductivité indiquent une relation salinité-densité dans la colonne d'eau des lacs. Plus précisément, les mesures effectuées directement sous la couche de glace et près du fond du lac variaient respectivement de 74 à 168 µS cm-1 et de 77 à 352 µS cm-1 en avril 2023, tandis que les conductivités de la surface et du fond du lac variaient respectivement de 44 à 111 µS cm-1 et de 73 à 488 µS cm-1 en septembre. En outre, les évaluations préliminaires des effets de la cryoconcentration sur la charge en solutés pendant les saisons de prise et de retrait des glaces indiquent une contribution potentielle aux écarts observés dans les conductivités de la colonne d'eau entre les deux saisons d'échantillonnage sur le terrain. Toutefois, il est essentiel de procéder à des analyses géochimiques supplémentaires pour valider cette hypothèse et explorer la possibilité d'autres phénomènes naturels qui pourraient expliquer ces différences.
