Summary: The Dual Scripps Plankton Camera (DSPC) presents a new approach for automated monitoring of phyto-and zooplankton communities. The DSPC demonstrates robust scaling with microscopy measurements in both laboratory and field applications, offering high temporal resolution and continuous sampling for a more detailed analysis of plankton dynamics. Comparing data from the DSPC to traditional methods shows overall agreement in diversity and abundance estimates, with the DSPC outperforming in the study of zooplankton community properties. The high frequency, reproducible, and real-time data provided by the DSPC expands our understanding of plankton ecology.

Summary: This study investigated the impact of grazing alien fish, Protosalanx chinensis, on the ecological equilibrium of lake plankton communities. The results showed that the stocking of P. chinensis did not deplete zooplankton resources and did not significantly affect biodiversity. However, there was a weakened correlation between phytoplankton and zooplankton in the lake where P. chinensis was stocked, indicating some effects on the ecological equilibrium. Long-term successive investigations are recommended for sustainable resource utilization and maintaining biological balance.

Summary: Springtime in temperate lakes is characterized by a phytoplankton bloom, followed by a grazing crustacean zooplankton bloom. The timing and species composition of these events may be influenced by antecedent conditions and climate change. Winter conditions have a strong impact on the succession and species composition of both phytoplankton and zooplankton.

Summary: Aquaculture has significant impacts on freshwater lakes, particularly on plankton communities. In this study, the effects of aquaculture on water quality, plankton diversity, and plankton metacommunity co-occurrence patterns were examined in a shallow freshwater lake. The results showed that ecological aquaculture was more efficient in nitrogen removal than ecological restoration. Moreover, lower bacterioplankton diversity but higher phytoplankton and zooplankton diversity were observed in the ecological aquaculture and ecological restoration zones. The lower network connectivity of the plankton metacommunities in these zones suggested a possible lower resistance to future disturbance. Additionally, different mechanisms drove plankton communities of different trophic levels.

Summary: The study investigated the recovery process of a small temperate lake from a natural flooding-induced browning and nutrient loading event. The findings suggest that browning events can lead to lasting changes in water chemistry, trophic status, and productive pathways of a lake, with a decline in pelagic production and only partial recovery of benthic production during the recovery period.

Summary: Phytoplankton dynamics are sensitive to various factors and stressors, and their response varies based on trophic state of the lake. This study in Washington State found that enhanced grazers reduced phytoplankton growth in oligotrophic lakes, while nutrient enhancement increased growth in certain lakes. Assemblage composition did not change significantly, but varied between sites and months. Different effects of grazers and nutrients were observed in low trophic systems, emphasizing the importance of considering trophic state in predicting phytoplankton response in lakes.

Summary: Concentrations of dissolved organic carbon (DOC) are increasing in lakes worldwide, which has significant effects on zooplankton. Deep chlorophyll maxima (DCMs) occur in lakes with lower DOC concentrations and provide an important resource for zooplankton. The increase in DOC can suppress zooplankton by affecting both resource quality and the availability of metalimnetic phytoplankton resources.

Summary: We studied the impact of high fish stock and top-down control on plankton structure and seasonal dynamics in nine fishponds. The fishponds were managed conventionally with supplemental feeding. The results showed that the fishstock had a strong influence on the microbial food web and led to a reduction in control by crustacean zooplankton. The trophic structure severely restricted the link between herbivorous zooplankton and fish during the vegetation season.

Summary: In this study, the effects of stocking common carp on plankton and periphytic microphytes in Lake Josava were examined. The results showed that after stocking, phytoplankton biomass declined and the community shifted towards small centric diatoms, allowing small-bodied zooplankton to exploit them. This led to reduced biomass of autotrophs and the zooplankton possibly began to feed on other sources.

Summary: The abundance of macroalgae is influenced by factors such as topography, wave exposure, and water residence time. Developing a new topographic index can help accurately predict the distribution of macroalgae. Models indicate that the topographic index, along with its interaction with water residence time, is the most significant factor affecting macroalgal abundance.

Summary: Lake respiration is supported by a combination of autochthonous and allochthonous resources, with temperature and organic matter inputs influencing the process. However, the variability in daily inputs can lead to fluctuations in respiration rates, with nutrients not directly tracking phytoplankton blooms in the lakes. Changes in hydrologic, climatic, and land use factors may result in linear responses in ecosystem processes like respiration.

Summary: Advances in understanding and predicting freshwater algal bloom dynamics have highlighted the significant role of groundwater inputs in modulating algal growth, depending on unique local conditions. The distinct chemistry of groundwater can either support or prevent algal blooms, with key mechanisms including the redox state of the subsurface and stability of groundwater discharge. More research is needed to improve predictions of algal blooms by considering changes in land use, water management, and climate impacting groundwater dynamics.

Summary: The frequency of heatwaves in rivers has been increasing in the United States, particularly in summer and fall, in mid- to high-order streams, and at free-flowing sites and sites above a reservoir. This increase in frequency is accompanied by an increase in moderate strength heatwaves and a doubling of the annual mean total number of heatwave days at a site. These heatwaves are often associated with normal or below-normal discharge conditions and occur at sites with lower mean annual discharge.

Summary: Dissolved organic carbon (DOC) plays a crucial role in aquatic ecosystems and has complex effects on ecosystem function. The study examined fluctuations in DOC at different timescales across 49 lakes in the Adirondacks, New York, USA, and found that DOC varied synchronously among lakes at within-season, annual, and interannual timescales. The causes of these variations differed across timescales, with external drivers explaining 78% of spatial DOC synchrony at the annual timescale.

Summary: Tropical cyclones impact estuaries through storm surge, flooding, high winds, and strong wave action. Previous studies have focused on individual locations or storm events, limiting generalizations about tropical cyclone impacts on estuaries. Using long-term and high-frequency measurements, we analyzed responses to 59 tropical cyclones across 19 estuaries in the eastern USA and found that salinity disturbances were more common and lasted longer than dissolved oxygen disturbances. Recovery time was correlated with disturbance severity, and storm properties and location characteristics influenced disturbance patterns.
