As transition zones between freshwater and the marine realm, Lagoon systems are especially vulnerable to anthropogenic influence due to their limited water exchange and challenging salinity regimes. To assess the environmental consequences of land use changes on water quality parameters under subtropical African conditions, 12 sites in Lagos Lagoon were sampled monthly over an entire year, covering the wet and dry seasons. The relationships between land use patterns and water quality were studied by combining seasonal water analysis results with GIS mapping based on satellite images. The results of the monthly water analysis showed a large degree of seasonality effects on almost all parameters but also some site-specific features pointing to local dominance of catchment area-related impacts. To unravel them, correlations between water parameters and land use patterns were analyzed based on a rough but robust classification. The land use forms were divided into five categories: waterbody, bare land, forest, urban area, and wetland. Independent of the restricted range of land use pattern variability covered by this study, several significant correlations between land use form and water quality parameters were found. Most of them are exclusively restricted to either the wet or dry season. Consistent season-independent significant correlations were found between the percentage of urban area and dissolved oxygen concentration. For wetlands, such consistent and significant correlations were found with nitrate, chemical oxygen demand, and turbidity. The findings provide first insights into the impact of land use changes on lagoon water quality under subtropical biodiversity of these systems and aquatic resources in general.</p>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"108 6","pages":"65-75"},"PeriodicalIF":0.9,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143252770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we evaluated the consequences of salt pulses in a manipulated mountain stream (central Portugal) with a salinized and a reference reach, assessing microbial decomposition of conditioned and nonconditioned chestnut (<i>Castanea sativa</i>) leaves, immediately after a period of NaCl exposure (daily short-term pulses for 7 days; salinization period) and 4 days after salt contamination cessation (recovery period). Conditioned leaves consistently presented higher mass loss, fungal biomass, and respiration rates than nonconditioned leaves. Leaf conditioning status modulated the deleterious effects of salinization, being more pervasive on the decomposition process of conditioned leaves. The depressing effect on mass loss and associated parameters promoted by daily pulses of salt on these leaves was extended after the cessation of salt contamination. This suggests salt legacy effects on already established microbial communities promoted by structural changes and/or mycelial physiological adjustments. In opposition, no effects of salinization were observed in nonconditioned leaves in either period. This may result from a potentially higher salt tolerance of the pioneer species that may also take advantage of the low basal salt concentration between salt pulses and/or of further incorporation of fungal species provided from upstream. Such continuous fungal imprint may result in redundant dissimilar (salinization period) or similar (recovery period) fungal decomposing communities able to determine balanced mass loss between sides in each period. Globally, results point to the importance of considering leaf litter quality and salt exposure timing in relation to leaf litter pulses when evaluating the consequences and delineating protection measures for streams facing discrete salt contamination.</p></div>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"108 4","pages":"37-44"},"PeriodicalIF":0.9,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143187031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the effects of climate change on the consumption of dissolved oxygen (DO) due to the mineralization of leachate from aquatic macrophytes is fundamental for accurately establishing the oxygen balance in aquatic systems and forecasting element cycling rates. Bioassays were developed to determine the consumption of DO owing to the mineralization of carbon and nitrogen of the aquatic macrophytes leachates (<i>Myriophyllum aquaticum</i>, <i>Hedychium coronarium</i>, <i>Salvinia auriculata</i>, and <i>Chara</i> sp.) when exposed to a temperature increase of 4°C (from 21°C to 25°C). The results concerning accumulated DO were fitted to a first-order kinetic model. At 25°C, oxygen consumption due to mineralization increased by 9.6%, whereas the chemical composition of the leachate changed oxygen consumption between 7.2 (21°C) and 9.2% (25°C). The O/C stoichiometry (oxygen consumed by oxidized carbon) indicated the compositions of the leachate, and temperatures determined the pattern of oxygen consumption. Due to the chemical composition of the leachate, the values varied by approximately 17% and were higher at 25°C (about 30%). Regardless, the increase in temperature improved the oxygen consumption of leachate mineralization. After 90 days at 25°C, the highest concentrations of remaining dissolved organic carbon occurred, suggesting the selection of microorganisms and the catabolic routes that favored the production of refractory organic compounds to the detriment of mineralization. The results indicate that knowledge of the effects of climate variations on aquatic systems is crucial for an accurate understanding of the biogeochemical cycles in these environments.</p></div>","PeriodicalId":54928,"journal":{"name":"International Review of Hydrobiology","volume":"108 5","pages":"49-59"},"PeriodicalIF":0.9,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143186296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, we not only underline alarming conditions of both species, but also question the effectiveness of currently employed stocking efforts. Given that both species are of increasing conservation concern, river basin-specific analyses are required to identify limiting factors on which conservation actions can be taken.

Study was designed to test for effect of human induced acidification. Using multivariate ordination techniques, we analyzed how variations in invertebrate composition are related to environmental factors. The results indicated that pH, hardness, total dissolved solids, and the content of ammonia and calcium were significantly associated with the distribution of invertebrates in the studied mining lakes. The highest iron content, relatively high values of conductivity, and chlorides were found in the extremely acidic mining lakes. A clear trend in decreasing density with decreasing pH was observed for taxa such as Oligochaeta, Chironomidae, Glossiphonidae, and certain taxa of snails. However, the density of other taxa such as Lestidae, Libellulidae, Caenidae, Sialidae, Helodidae, Hydrophilidae, and Polycentropodidae increased with decreasing pH. Specific communities were found with increasing acidity. Therefore, a further increase in acidity will probably cause a stronger decline in most of taxa and their density, and on water chemistry (e.g., calcium concentration, nitrites, and hardness).
