Natural river landscapes can be biodiversity hotspots but are one of the most human altered ecosystems with habitats significantly damaged around world, and a third fish populations threatened extinction. While riparian have been negatively by anthropogenic activities, effective planning restoration strategies reverse negative impacts improving habitat quality. However, restoring rivers requires appropriate data on current health while also considering priorities for different stakeholders. To address this, Geographic Information System (GIS) was used to create new transferable priority model based section Linth in Switzerland as case study. The is founded connectivity, condition, national species hotspots. Landscape change zone analyzed using aerial imagery landscape metrics. Almost quarter within study area were considered high or very priority, many aquatic set benefit from restoration. From 1946 2019, became highly fragmented due significant growth impervious surfaces concomitant loss agricultural land. GIS provides tool which environmental agencies manage natural features over large scales, targeting conservation areas greatest need.

Riparian topographical features can drive a suite of ecological indicators (EIs) that shape the river ecosystem. The mechanisms EIs reflect provide several ecosystem services. We know little about responses (indicators plant cover, regeneration, exotics, habitat, erosion, and stressors) to changing stream-channel width, riparian elevation lengthy drawdown zones (upstream, midstream, downstream) long rivers. have discovered characteristics affect buffer areas differently by using rapid field-based method with 297 transects in inundated regions along Yangtze River other 36 linked tributaries China. Changing widths was most effective on downstream least at midstream. exotic parameters were affected (with range −0.36 < r 0.401) widths, as determined Pearson correlation ( p 0.05). In contrast, width had uppermost impact upstream lowermost downstream; significant habitat ≤ 0.787). followed pattern negatively associated exotics −0.645 −0.594) positively correlated regeneration 0.569). These results reaffirm imperative need for studies regionally dependent maintained under same management strategies regardless their features. Future policies should be formulated enhance service provision, promoting sustainable use extensive ecosystems while considering EIs. Additionally, these future acknowledge zone factors within network. Furthermore, additional measures are conserve prevent further destruction.

Abstract Few factors are as important in determining water quality land use/land cover (LULC). Many use activities, including agriculture, urban development, mining, and commercial forestry, tend to be sources of diffuse pollution. By contrast, indigenous vegetation can act a sink, thus providing some protection from anthropogenic contamination. Notwithstanding the large body research demonstrating these facts, decision-makers require clear accessible information assist them developing effective management plans that fully cognisant manifold impacts LULC on resources. Reviewing available literature, this article, therefore, offers critical overview typical quality. An strategy for managing highlighted article is maintenance sufficient amount unfragmented natural vegetation, not only within riparian zones but also across catchment areas. However, knowledge gaps identified review indicate further context-specific required determine types minimum vegetative protect resources pollution potential impact landscape fragmentation ability A discussion therefore provided.

Land use/land cover (LULC) can have significant impacts on water quality and the health of aquatic ecosystems. Consequently, understanding quantifying nature these is essential for development effective catchment management strategies. This article provides a critical review literature in which use statistical methods to model LULC demonstrated. A survey publications, included hundreds original research articles, revealed several common themes findings. However, there are also persistent knowledge gaps, areas methodological uncertainty, questions application that require further study clarification. These relate primarily appropriate analytical scales, significance landscape configuration, estimation thresholds, as well potentially confounding influence extraneous variables. Moreover, geographical bias published means need ecologically climatically disparate regions, including less developed countries Global South. The focus this not provide technical techniques themselves, but examine important practical considerations their modelling quality.

Histopathology has been used as a very useful tool to provide information on the severity of tissue damage, injuries, and organ functionality. Thus, this work aimed assess whether seasonal variations (summer winter) in water quality had consequences liver histology Iberian barbel (Luciobarbus bocagei) Douro nase (Pseudochondrostoma duriense). The research was carried out Vilariça River, tributary Sabor River Portugal, which is spawning grounds by these endemic cyprinids. histopathological changes, assessed through semi-quantitative system, allowed identification 13 changes located hepatic parenchyma, bile duct, blood vessels. with higher prevalence both species were vacuolization hepatocytes, endothelial rupture, necrosis, fibrosis, degenerative vacuolization. results showed that degree histological alterations ranged between moderate severe, major observed L. bocagei, summer season, at sampling points downstream middle stream. canonical analysis indicated exposure fish metals may increase potential risk damage. summer, high concentrations Fe, Cu, Zn, As, Mn justified biliary duct epithelial detachment, species, hyperplasia epithelium, bocagei. In winter, TSS Cd, Ni, Cr congestion vessels species. hepatosomatic index caught winter due presence hepatocyte reflected differences type contaminants different seasons periods, thus proven valuable indicator quality.
