Monitoring and modelling landscape structure, land use intensity and landscape change as drivers of water quality using remote sensing

The Science of The Total Environment, Journal Year: 2025, Volume and Issue: 960, P. 178347 - 178347

Published: Jan. 1, 2025

The interactions between landscape structure, land use intensity (LUI), climate change, and ecological processes significantly impact hydrological processes, affecting water quality. Monitoring these factors is crucial for understanding their influence on Remote sensing (RS) provides a continuous, standardized approach to capture structures, LUI, changes over long-term time series. In this study, RS-based indicators from Landsat data (2018-2021) were used assess change study area in northern Germany, applying the ESIS/Imalys tool. These then model predict quality (Chl

Chemodiversity of Cyanobacterial Toxins Driven by Future Scenarios of Climate Warming and Eutrophication

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(32), P. 11767 - 11778

Published: Aug. 3, 2023

Climate change and eutrophication are two environmental threats that can alter the structure of freshwater ecosystems their service functions, but we know little about how ecosystem function will evolve in future scenarios climate warming. Therefore, created different experimental scenarios, including present-day conditions, a 3.0 °C increase mean temperature, "heatwaves" scenario (i.e., an temperature variability) to assess effects on phytoplankton communities under simultaneous stress from herbicides. We show warming, particularly heatwaves, associated with elevated cyanobacterial abundances toxin production, driven by mainly nontoxic toxic Microcystis spp. The reason for higher concentrations is likely because dual pressures warming individual toxin-producing ability decreased. Eutrophication temperatures significantly increased biomass Microcystis, leading concentrations. In contrast, alone did not produce or due depletion available nutrient pool. Similarly, herbicide glyphosate affect any taxa. case enrichment, were much than strong boost potential producers.

Multiple‐stressor effects on leaf litter decomposition in freshwater ecosystems: A meta‐analysis

Functional Ecology, Journal Year: 2024, Volume and Issue: 38(7), P. 1523 - 1536

Abstract Recent years have witnessed a surge in research on the effects of multiple stressors freshwater ecosystems. While studies increased, synthesis their findings into broader understanding ecosystem‐level remains an ongoing endeavour. Leaf litter decomposition, frequently investigated and pivotal ecosystem function freshwaters, is sensitive to changes abiotic conditions biotic communities, therefore susceptible multiple‐stressor effects. Here, we synthesize from 27 manipulative experimental encompassing 61 responses decomposition paired such as warming, nutrient enrichment emerging pollutants We calculated individual overall interaction effect sizes resulting two occurring simultaneously. Furthermore, analysed moderator variables size direction using meta‐analytical approach. Although vote‐counting method showed additive interactions dominate observations (91.8%), weighted random‐effects meta‐analysis revealed antagonistic between (i.e. cumulative was less than sum single effects). Our results emphasized influence characteristics macroinvertebrate involvement, habitat type (lentic vs. lotic) quality (assumed plant mycorrhizal association) shaping stressors. highlights need incorporate local ecological complexities experiments improve predictions biodiversity functions.

River culture: How socio‐ecological linkages to the rhythm of the waters develop, how they are lost, and how they can be regained

Geographical Journal, Journal Year: 2022, Volume and Issue: 190(2)

Published: Aug. 23, 2022

Abstract The hydrological patterns of all natural water bodies pulse in variable rhythms high and low water. biodiversity these ecosystems is driven by the changing nature environment, allowing different life strategies to coexist, e.g., fast reuse nutrients when aquatic biota flourish recently wetted zones vice versa. Much human culture hydroscapes has developed as an adaptation this rhythm, using flood‐fertilised floodplains for agriculture or fisheries, seasonal migration into out floodplain (transhumance). Technological advances have allowed humans control, change, even eliminate rhythm building dams, dikes, canals. Consequently, important ecosystem functions fail, often resulting failure life‐support systems but also decline cultural activities. I argue that loss socio‐cultural connectivity rivers other hydrosystems occurs four phases: (i) direct relationships (e.g., uses waterborne resources), (ii) indirect (cultural activities are connected theses uses), (iii) turning away from river/hydrosystem (often caused decreased quality), (iv) total oblivion (caused removal burial hydrosystem). Reintegrating more riverine would not mean step back time rather find a combination revised traditional ecological knowledge, learning nature, values context use resources, innovations. This paper draws on social‐environmental aspects River Culture Concept – which attempts reintegrate respect pulsing modern, sustainable management diverse case studies.

Disentangling effects of multiple agricultural stressors on benthic and hyporheic nitrate uptake

Biogeochemistry, Journal Year: 2024, Volume and Issue: 167(3), P. 287 - 299

Published: March 13, 2024

Abstract Agricultural land use alters nitrate (NO 3 – ) uptake dynamics in streams, but the specific mechanisms linking individual agricultural stressors to benthic and hyporheic remain unclear. Using stream-side mesocosms 15 N-nitrate additions, we examined combined effects of fine sediment (FS) augmented light phosphorus levels (L&P) on NO rates. In absence FS, L&P stimulated autotrophic heterotrophic biofilms, leading a 12- 7-fold increase compartments, respectively. Under ambient nutrient conditions, FS reduced by 3-fold uptake, were not significant. Conversely, compartment, induced anoxic likely stimulating denitrification causing 14-fold uptake. When these combined, they did interact compartment. compartment interacted antagonistically, with diminishing FS. Our results indicate that previously observed whole-stream streams is attributable nutrients while role total are modest. Moreover, finding stressor interactions vary ecosystem compartments calls for consideration all their contribution whole-system functioning multiple studies. We beginning understand how interacting affect stream functioning, more mechanistic evidence needed disentangle whether additive or non-additive prevail human-altered ecosystems.

Floodplains provide an extraordinary quantity and quality of ecosystem services (ES) but are among the most threatened ecosystems worldwide. The uses transformations floodplains differ widely within between regions. In recent decades, diverse pressures requirements for flood protection, drinking water resource biodiversity, adaptation to climate change have shown that multi-functional floodplain management is necessary. Such integrative approach has been hampered by various interests different sectors society, as represented multiple stakeholders legal principles. We present innovative framework integrated building up on ES multi-functionality stakeholder involvement, forming a scientifically based decision-support prioritize adaptive measures responding at basin local scales. To demonstrate its potential limitations, we applied this cross-scaled in world's international culturally basin, Danube River Basin Europe. conducted large-scale evaluations anthropogenic capacities one hand participatory modelling socio-ecohydrological systems other hand.
