Summary: Temporal and spatial heterogeneity in the distribution of cladocerans in lakes is influenced by abiotic and biotic factors. The diel vertical and horizontal migrations of cladocerans were studied in two deep lakes in the Czech Republic, revealing differences in distribution patterns due to macrophyte cover and fish assemblages. Temporal variations and diurnal deficits in cladoceran assemblages were observed in both lakes.

Summary: The production of highly toxic monomethylmercury (MeHg) is unevenly distributed in the water column. The role of water column heterogeneity, especially zooplankton grazers, in mercury (Hg) cycling is still not well understood. This study found a significant association between the presence of zooplankton and the concentrations of dissolved total Hg (DTHg) and total Hg (THg) in the water. Results suggest that the heterogeneity of biotic factors, including phytoplankton and zooplankton, plays a key role in the cycling of total Hg and MeHg in boreal lakes.

Summary: Understanding the diel vertical migration patterns of zooplankton is important for biological pumping and pelagic food webs. However, limited knowledge exists about the DVM patterns of zooplankton with different functional traits. This study used a trait-based approach to investigate the vertical distributions of zooplankton in the North Pacific Subtropical Gyre, and found that different functional groups exhibited distinct DVM patterns.

Summary: Vertical behavior, such as diel vertical migration (DVM) and swarming, is widespread among zooplankton. In the Norwegian Sea, synchronized DVM and large near-surface swarms were observed in the zooplankton community. The zooplankton community was concentrated in the upper 20 meters in calm weather but retreated to greater depths in the presence of increased near-surface turbulence, indicating synchronized schooling behavior.

Summary: This study developed an automated, quantitative method for detecting diel vertical migration (DVM) using 2D cross-correlation. The method showed better performance than previous methods and had a high detection rate of 88%. This method provides a robust and efficient way to analyze DVM behaviors in ocean environments.

Summary: The study observed a previously undescribed phenomenon, where an acoustic scattering layer with a daytime depth of 300 m in the subpolar Northeastern Pacific Ocean underwent rapid, high-frequency vertical migrations significantly correlated with cloud-driven variability in surface photosynthetically available radiation.

Summary: Partial diel vertical migration (DVM) in Daphnia populations does not depend on individual size or genetic polymorphism, and the mechanisms maintaining this behavior are unclear. Observational approaches have shown that intraspecific diversity in body hemoglobin concentration may play a role in maintaining partial DVM.

Summary: Vertical migration behavior among zooplankton includes both diel vertical migration and seasonal vertical migration, controlled by ambient irradiance and seasonal environmental deterioration respectively. These migrations play a significant role in the vertical transport of organic carbon to deeper waters (biological carbon sequestration) and in the buffering of global climate change.

Summary: Records from moored Acoustic Doppler Current Profilers (ADCP) provide new insights into the dynamics of deep scattering layers (DSL) and diel vertical migration (DVM) of mesopelagic biomass in the southern Norwegian Sea, with seasonal variations and optical conditions influencing the activity of pelagic and mesopelagic species in the region.

Summary: Diel vertical migration (DVM) is a behavior observed in zooplankton worldwide, influencing biogeochemical cycling and prey availability. This study focuses on the second-order variability in DVM timing, which can help identify factors influencing migration timing and demonstrate changes in DVM behaviors. The findings highlight the importance of considering seasonal variability and context-specific parameters when studying DVM behaviors.

Summary: The optical chain and logger (OptiCAL) is an autonomous ice-tethered observatory equipped with multiple light sensors for mapping the variation of light with depth. It can cover a high dynamic range of under-ice light levels and produce realistic values compared to modeled surface irradiance. The raised light levels at specific depths associated with nearby leads in the ice highlight the importance of depth-resolved light measurements.

Summary: Through studying the seasonal and diel changes of the zooplankton community in Comau Fjord, it was found that zooplankton biomass was highest in summer and lowest in winter, while abundance peaked in spring. Copepods were identified as the most important group in terms of abundance and biovolume.

Summary: The study revealed that even in extreme photic conditions, there is a widely rhythmic daily transcriptome, indicating that very weak solar cues are enough to synchronize organisms. At extremely high latitudes and under sea-ice, gene oscillations are re-organized to include < 24h rhythms. Environmental synchronization may be modulated to include non-photic signals (such as tidal cycles).

Summary: Zooplankton can spend winter actively under lake ice, with only a fraction contributing to an active food web due to limited and unrewarding feeding opportunities. Zooplankton fatty acids under ice mostly come from previously accumulated fat storage, with little contribution from under-ice seston assimilation. The food web under lake ice is supported by mixotrophic phytoplankton, resulting in few trophic linkages and low connectance in the planktonic community.

Summary: Land use and climate change are expected to impact phytoplankton in lakes globally, but the effects vary significantly depending on the region and lake sensitivity. Urbanization is identified as a major driver of phytoplankton development in urban lakes, while climate plays a major role in lakes located in remote areas.

Summary: Invasion of non-native species may affect food web structure and control within lake ecosystems. Comparative analyses of feeding rates of invasive sticklebacks and native whitefish found that competition existed between the two species, but the invasion of sticklebacks is unlikely to change the feeding pressure on zooplankton species.

Summary: The introduction of the invasive Round Goby has resulted in complex changes in the food web of Oneida Lake, New York. The Round Goby has significantly reduced the density of several benthic invertebrate species and their consumption by fish. However, the negative effects on the growth of Yellow Perch and White Perch have been offset by the consumption of Round Goby and the expansion of burrowing mayflies.

Summary: Bythotrephes longimanus is a predatory zooplankton that can decrease Daphnia abundance and potentially impact the growth rates of native planktivorous fish. The recent invasion of Bythotrephes in Oneida Lake provided an opportunity to study the feeding habits and growth of yellow perch. Surprisingly, age-0 yellow perch selected for Bythotrephes as part of their diet without negatively affecting their growth. The presence of Bythotrephes, along with other factors like temperature and Daphnia biomass, had a positive effect on the October length of age-0 yellow perch.

Summary: Coregonine fishes, including lake whitefish and cisco, exhibit similar habitat use during the larval stage, with subtle distributional differences driven by hatch timing and ontogenetic habitat shifts. Our study provides additional evidence that the early life histories of these species are highly similar and does not support the hypothesis that larval habitat use differences are a major driver of differential recruitment success.
