Unravelling the role of sulphate in reed development in urban freshwater lakes
The authors analysed data from 14 lakes in the Berlin catchment area for the period 2000 to 2020. They found that if sulphate concentrations had not increased, there would be about 20 per cent more reeds in the sulphate-polluted lakes today.
Ecosystem-based management outperforms species-focused stocking for enhancing fish populations
In a large-scale effort, a research team in cooperation with angling clubs, has conducted whole-lake experiments in 20 lakes to improve ecological conditions. Habitat improvements were the most effective means to enhance fish populations, whereas fish stocking completely failed. The study emphasizes the importance of restoring habitats and improving natural ecosystem processes.
Worldwide moderate-resolution mapping of lake surface chl-a reveals variable responses to global change (1997–2020)
Whether a lake appears blue or green is also related to its chlorophyll-a content. Researchers led by IGB used satellite data to draw conclusions about the concentrations of the green pigment produced by algae.
Upscaling Tracer-Aided Ecohydrological Modeling to Larger Catchments: implications for Process Representation and Heterogeneity in Landscape Organization
The authors adapted a tracer-aided ecohydrological model to upscale tracer-informed process representation to larger catchments scales. The modeling unravelled spatio-temporally varying patterns of water storage-flux-age interactions and their interplay under drought. Insights into ecohydrological functioning at scales relevant to management decision-making are important for guiding interventions.
Fungal parasitism on diatoms alters formation and bio–physical properties of sinking aggregates
The Asymmetric Response Concept explains ecological consequences of multiple stressor exposure and release
Multiple stressors can affect species indirectly through either abiotic variables or impacts on non-target species. Stress tolerance is the key determinant of responses to increasing stress intensity. Dispersal and biotic interactions are the two key mechanisms governing responses to the release from stressors.
Enhancing urban runoff modelling using water stable isotopes and ages in complex catchments
Hydrological and water stable isotope datasets within a modelling framework were utilized to evaluate the water flow paths and ages in the heavily urbanized Panke catchment in Berlin. Groundwater was the primary flow component in reaches with less urbanisation. Wastewater effluent dominated the mid-reaches with direct storm runoff and shallow subsurface contributions in the urbanized reaches.
Leveraging big data to uncover the eco-evolutionary factors shaping behavioural development
In this review, the authors provide a guide to state-of-the-art approaches that allow the collection and analysis of high-resolution behavioural data across development. They outline how such approaches can be used to address key issues regarding the ecological and evolutionary factors shaping behavioural development.
Integrating urban water fluxes and moving beyond impervious surface cover: a review
This review paper by international female experts on urban hydrology identifies gaps in our understanding of how water flows through built landscapes. It focuses on key topics within urban hydrology related to water quantity, incl. runoff and streamflow generation, soils and soil water, groundwater, vegetation, and climate; describes challenges and opportunities in the field of urban hydrology.
