Summary: Diel vertical migration (DVM) is a common phenomenon in aquatic environments, where zooplankton migrate to deeper waters to avoid predation. This study investigates hypotheses related to morphology and DVM using in situ imaging and introduces a robust method for quantifying DVM. The results show that larger and darker copepods have a larger DVM signal.

Summary: We used a bi-static lidar system based on the Scheimpflug principle to measure flying insects above and near a small lake in a forested area in Southern Sweden. The system has a high spatial resolution at close distance but declines further from the sensor due to the compact design. Our study found an increase in insect abundance at dusk and dawn, and a decrease over water compared to over land. Larger insects were also more commonly found over water, and the average size of insects increased at night.

Summary: The winter zooplankton community in Lake Kulonga, located in the Arctic regions of Russia, exhibited specific dynamics influenced by the density of fish predators. The copepod Macrocyclops albidus dominated in terms of biomass at deep-water stations, while old copepodites of Cyclops spp. were prevalent at deep-water stations in terms of abundance. Overall, the abundance and biomass of zooplankton in winter showed significant variations among different taxa and stations.

Summary: This study analyzed biodiversity inventories of 67 French lakes and found that temperature, productivity, and habitat characteristics have significant influences on food web structure. The size and complexity of habitats have a greater impact on overall trophic diversity, while water thermal seasonality and habitat depth have a greater impact on vertical structure. The study highlights the importance of considering temperature, productivity, and habitat characteristics, especially in the context of global change, as these factors can lead to significant structural changes in aquatic food webs.

Summary: This study found that bdelloid rotifers and ostracods (Heterocypris incongruens) were the most common taxa hatched from sediment in stormwater management systems. Laboratory experiments revealed that Cx. restuans larvae reared with H. incongruens had shorter development time, larger adult size, and female-biased sex ratios compared to those reared alone. These findings emphasize the importance of understanding interspecific interactions in influencing larval mosquito development traits.

Summary: Previously overlooked, winter is now recognized as a significant period of biological activity in north-temperate lakes. Research suggests that changes in ice cover duration and snow conditions could have substantial impacts on aquatic ecosystems. This study investigates the potential consequences of changing ice and snow dynamics on aquatic biological communities, specifically focusing on lower trophic levels.

Summary: In phytoplankton communities, spatial overlap may promote competitive exclusion and reduce taxonomic diversity, while also fostering functional diversity. This study found that alterations in lake physical structure and zooplankton community had a stronger impact on phytoplankton diversity than spatial overlap. However, some effects of spatial overlap on competitive interactions were still observable in the system.

Summary: The study investigated the spawning behavior of Lake whitefish in the major tributaries of Green Bay, Wisconsin, and found that adult fish primarily spawn in cobble substrate areas in November when temperatures drop below 8 degrees Celsius. Through hydroacoustic imaging and egg/larval surveys, it was discovered that the tributaries produced 452,000 whitefish larvae in 2017 and 721,000 larvae in 2018. This represents the first documentation of successful lake whitefish larval production in Green Bay tributaries.

Summary: The impact of solar ultraviolet radiation on aquatic zooplankter Daphnia magna depends on its fluctuating nature, with lower fitness costs associated with less fluctuating UVR exposure. Individuals exposed to long-term UVR did not exhibit behavioral plasticity. Populations may respond with alternative strategies depending on the variability of stressors in nature.

Summary: The study found that the response of phytoplankton to ultraviolet radiation largely depends on nutrient availability, with no significant responses in oligotrophic raw water but positive responses in nutrient enrichment. Additionally, different phytoplankton taxa exhibit varied responses to UV radiation, with chlorophytes and dinoflagellates showing positive responses, chrysophytes being sensitive, diatoms showing no significant response, and cyanobacteria's response being nutrient-dependent.

Summary: Traditionally, lakes are classified based on their thermal regime and trophic status, but this classification method is not sufficient to understand seasonally ice-covered lakes. Research has found that differently sized and deep seasonally ice-covered lakes exhibit different thermal stratification characteristics, leading to the proposal of new classification terms.

Summary: This study found that reductions in ice cover duration and earlier ice breakup in lakes due to climate warming can lead to changes in the duration of spring mixing and summer stratification. The timing of ice breakup showed a relationship with spring mixing duration, with differences observed based on latitude. The projected earlier ice breakup could result in nonlinear changes in the relative duration of spring mixing and summer stratification, impacting oxygen depletion severity differently across latitudes.

Summary: Long-term temperature changes in lakes lead to thermal habitat changes, exacerbated by seasonal and depth-related constraints. Tropical lakes show higher thermal non-overlap compared to lakes at other latitudes, and lakes with high biodiversity and endemism exhibit higher thermal habitat changes.

Summary: Inland waters play an important role in connecting terrestrial landscape and oceans, but their contribution to global carbon budgets is often overlooked. This study synthesizes recent estimates of carbon fluxes in different types of inland waterbodies and highlights the impact of anthropogenic pressures on these fluxes. The study also recommends research priorities for better understanding and quantification of carbon fluxes in response to climate and landscape changes.

Summary: In the transition to low-carbon electricity, accurate estimation of carbon dynamics in hydropower reservoirs is crucial. However, existing research has limitations such as neglecting the position and operation of reservoirs in a freshwater network, lack of statistical foundation for global estimates, inaccurate carbon attribution methods, and overlooking the importance of time. Addressing these issues can help uncover pathways to meet energy demand while minimizing carbon emissions and their impact on aquatic ecosystems.
