The aim of this work was to assess the capacity of these areas to shelter soil fauna, contributing to their conservation in the urban environment. It also aimed to assess which soil attributes and landscape features most interfere with the occurrence and abundance of these soil invertebrates. Fifteen areas were selected in the neighborhoods of Campo Grande and Vargem Grande, in the West Zone of the municipality of Rio de Janeiro, making up a gradient of different plantations and forest areas. In each area, a transect was established with three sampling points 5 m apart, where the soil mesofauna was sampled with a specific auger, collecting litter and soil up to 10 cm. Earthworms were sampled using the TSBF method at a depth of 0–10 cm. Soil samples were collected at each fauna sampling point, at the same depth, for routine analysis of soil fertility and texture. The data was analyzed using multivariate techniques, first using principal component analysis (PCA) to select soil attributes representing the local scale of influence and percentages of landscape features. The percentages of landscape features were measured using two buffers around the sampling area, 500 m and 250 m. A multidimensional scaling (NMDS) analysis was carried out to select the fauna groups with the greatest representativeness and degree of response to environmental factors. Environmental factors at the local scale and at the 500 m and 250 m scales were determined using generalized linear model (GLM) analysis, through which it was possible to select models composed of variables that determine the occurrence and density of the different groups of fauna selected. The most abundant groups were Acari, Collembola Entomobryomorpha, and Formicidae. In the crop areas, Acari was dominant, while in the forest area used as a reference Entomobryomorpha was more abundant. On a local scale, pH was the most common factor in the models, often with a negative sign, showing an inverse relationship between the pH value and the density of the fauna group. This result suggests that pH is a good indicator for correlations with soil mesofauna and earthworms. The 250 m models were able to select groups with a greater affinity for crops and highly anthropized areas. In conclusion, it was observed that these areas are capable of maintaining an abundant and diverse community of soil fauna.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 10","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145170412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These indices were analysed using Slow Moving Average regression, which revealed significant declines in vegetation health following oil spill events.

A random forest classifier further quantified the extent of contaminated land cover, demonstrating the effectiveness of this method for monitoring environmental damage in this challenging terrain. Contaminated vegetation, wetland, farmland, and grassland cover approximately 4% (1180 ha) of the total Niger Delta area.

However, the mechanisms through which organic acids released during cyanobacterial accumulation, in conjunction with high nitrogen inputs, drive fluctuations in total phosphorus (TP) concentration in Lake Taihu remain unexplored. In this study, organic matter from decomposed bloom-forming cyanobacteria and nitrate were sequentially added to sediments to evaluate their effects on the fluctuation of TP concentration. Statistical analysis revealed that from 2012 to 2023, the total nitrogen (TN) concentration in Lake Taihu decreased in tandem with declining TN levels in inflowing rivers. In contrast, the TP concentration in the lake water exhibited significant fluctuations despite a continuous decrease in TP loading from the inflowing rivers. High-density bloom-forming cyanobacteria were found to enhance phosphorus release from sediments due to Fe(III) reduction to Fe(II), whereas nitrate–nitrogen (NO<sub>3</sub><sup>−</sup>–N) appeared to promote phosphorus assimilation in sediments under low cyanobacterial density. Microcosm experiments demonstrated that cyanobacterial organic matter significantly enhanced phosphate release from sediments. Thus, cyanobacterial organic matter may have facilitated a shift in phosphorus dynamics from a sink to a source in the sediments of the western lake region of Lake Taihu before 2019. Conversely, from 2019 to 2023, NO<sub>3</sub><sup>−</sup>–N inputs from rivers stimulated Fe(II) oxidation, leading to phosphate binding with Fe(III) and enhancing phosphorus retention in sediments. This process reversed phosphorus from a source to a sink in sediments. These findings reveal a bidirectional source–sink switch regulated by cyanobacterial bloom intensity and nitrate loading, providing a mechanistic explanation for TP fluctuations in Lake Taihu between 2012 and 2023. The study offers broader insights into internal phosphorus cycling and eutrophication management in shallow lakes.</p></div>","PeriodicalId":544,"journal":{"name":"Environmental Monitoring and Assessment","volume":"197 10","pages":""},"PeriodicalIF":3.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focusing on the Shapotou region of Ningxia, this study collected bathymetric data using an unmanned surface vessel and employed interpolation methods and machine learning (XGBoost) to determine the most effective approach for constructing the lake digital elevation model (DEM). The relationship curve between water area, water level, and water reserve, derived from DEM analysis and calculation, is integrated with remote sensing imagery, thus facilitating the efficient monitoring of lake water dynamics. This approach provides valuable scientific and practical support for water resource management in remote or data-scarce regions lacking conventional hydrological infrastructure.

However, these marshes may pose an ecological trap – attracting rails despite high selenium exposure. We captured rails during the 2020–2023 breeding seasons and compared rail selenium levels within three types of marshes (fed with irrigation runoff, Colorado River water, or groundwater). We collected blood, breast feathers, and head feathers of rails in all three water sources for selenium comparisons. We tagged adult rails with GPS transmitters to locate nests and foraging locations where we collected eggshells, unhatched eggs, and prey. We assessed selenium exposure by collecting multiple prey species commonly eaten by rails in all three water sources. Selenium concentrations varied among sampling locations. Selenium concentrations in most sample types were predominately influenced by water source and marsh inflow velocity (sometimes in combination with marsh size). Distance to inflow, however, did not influence selenium concentrations in any sample type. Selenium concentrations were highest in agricultural-fed marshes compared to river-fed and spring-fed marshes. Increased marsh inflow velocities resulted in lower selenium concentrations.
