Abstract Sustainable management of lakes requires us to overcome ecological, economic, and social challenges. These challenges can be addressed by focusing on achieving ecological improvement within a multifaceted, co‐beneficial context. In‐lake restoration measures may promote more rapid ecosystem responses than is feasible with catchment alone, even if multiple interventions are needed. In particular, we identify methods that support the overarching societal target circular economy through...
The hypertrophic Swarzędzkie Lake, Poland, is characterized by high species diversity, abundance and biomass of both phytoplankton zooplankton (up to 99.5 mg WW L−1 817.75 μg DW L−1, respectively). community grazing rate calculated with the use two empirical models, based on herbivorous crustaceans, peaked in spring early autumn up 150.6% water filtered per day, was lowest during winter. Simple statistics revealed a positive correlation between chlorophyll concentration (r = 0.404, P 0.033)...
The ribbon type Lake Durowskie (Western Poland) is currently undergoing a sustainable restoration process due to water quality deterioration, manifested in blooms, low transparency, and oxygen deficits near the bottom sediments. Three methods were applied: (i) hypolimnion aeration using two wind-driven pulverizing aerators installed at deepest places, (ii) phosphorus inactivation small doses of iron sulfate magnesium chloride several times year, (iii) biomanipulation pike fry stocking....
Uzarzewskie Lake is a small, postglacial lake, located in western Poland. The lake under restoration treatment since 2006. At first, iron was done for 2 years. In the second stage, spring water directed into hypolimnion order to improve oxygenation near bottom sediments. purpose of our research determine changes contribution functional groups total number taxa and biomass phytoplankton due physical chemical characteristics restored lake. Phytoplankton composition analyzed three periods: (1)...
Abstract The study covered a small, shallow lake, intensively used for recreation (sailing, tourist services and port infrastructure). This aimed to determine the spatial differentiation of bottom sediments potential phosphorus release in five zones, differing mainly type recreation, depth, direct catchment management, shoreline management macrophyte presence. results were propose protective restoration measures improve water quality studied lake. innovation was detailed analysis sediments,...
Nature-based solutions in lake restoration enable gradual ecosystem reconstruction without drastic and expensive intervention. Sustainable involves limited external interference strong enough to initiate maintain positive changes the ecosystem. It was introduced Lake Durowskie, an urban, flow-through situated Western Poland, using hypolimnetic aeration, phosphorus precipitation with small doses of chemicals biomanipulation 2009, is continued until today. Oxygen conditions hypolimnion after...
Successful management of lake ecosystems used for recreation requires firstly an identification nutrient sources. It is necessary to identify the factors causing deterioration water quality and plan measures their mitigation. Analyses external internal loading were carried out hypereutrophic Raczyńskie Lake. The study included flows from tributaries, stormwater runoff impermeable areas direct catchment impact as sources nitrogen phosphorus, well bottom sediments source phosphorus. In case...
Groundwater intake near Lake Głębokie, situated in the city of Szczecin Northwestern Poland, resulted a distinct decrease lake water level. Water from river and neighboring urban area led to eutrophication strong cyanobacterial bloom. Both recreation were threatened due possible influence toxins. The was subjected three sustainable restoration methods: aeration sediment-water; iron addition precipitate P, and; biomanipulation. goal our study determine changes taxonomic composition...
Functioning of the Lake Rusałka ecosystem in Poznań (western Poland) is a shallow, artificial, strongly eutrophic reservoir. Thermal stratification weak and comprises only about 8% bottom surface. In summer, epilimnion oversaturated with oxygen due to intensive phytoplankton growth (chlorophyll up 80.2 μg l -1 ), while conditions hypolimnion are anaerobic. The high concentration ammonium nitrogen low N:P ratio stimulated intense cyanobacteria period from June November. domination rotifers...
Abstract This paper presents the preliminary results of a study phytoplankton structure and dynamics physicochemical properties Lake Swarzędzkie in 2011. The subject is shallow, elongated, post-glacial lake located western Poland. surface area 93.7 ha with maximum depth 7.2 m. Its poor water quality led to implementation chemical biological restoration procedures an attempt improve it. highest concentration total nitrogen was 13.07 mg l -1 N. Secchi (SD) low summer minimum value 0.5 m...
Abstract Phosphorus release from bottom sediments studied in two zones of Lake Uzarzewskie differing depth and water oxygenation displayed seasonal spatial variability. The experiments indicated that the lake receives considerable internal loading, especially deeper, anaerobic, rarely-mixed part lake. Meanwhile, shallow zone situated 0-3 m range, could be a sink for phosphorus during spring source other seasons year. total loading was over 950 kg year -1 P, 83% this amount originated deeper...
Abstract Experimental research conducted on bottom sediments from the eutrophic Lake Rusałka (Poznań, Poland) indicated that phosphorus release process has a significant influence functioning of ecosystem. Internal loading was very intense in deepest part lake, where it reached up to 29.84 mg m -2 d -1 P under anaerobic conditions. This however, insignificant overall internal loading. The highest lake shallows, which covered 92% area. Total mean annual ecosystem 1214.5 kg year P, i.e., 3.31 g P.
Continuous nitrate treatment is an innovative, nature-based and cost-effective restoration method that has been implemented in a small, hypereutrophic lake by redirecting the nitrate-rich waters of lake's natural tributaries into its hypolimnion. The aim this to increase redox potential at sediment-water interface order provide conditions for efficient phosphorus binding. To assess effects treatment, studies physico-chemical biological parameters were carried out before application (PreNT -...
Abstract Zooplankton phosphorus excretion was studied in Swarzędzkie Lake 2000-2002. Phosphorus rates were high from spring through autumn, but low winter. The highest value, 203.7 μgP 1 -1 d (vertical profile mean), recorded June 2000. mean rate 26.6 and 10 times greater for rotifers than both cladocerans copepods. In most months, the calculated sum of tributary external loading internal bottom sediment loading. Nevertheless, influence zooplankton on yearly phytoplankton abundance, biomass...
