Abstract:
... Climate change is likely to stimulate variations in phytoplankton composition and production in gradually eutrophicating water, with negative consequences for the water quality of many reservoirs. This study analyzed the effects of climate warming and increased nutrient loading on algae communities recorded by sedimentary pigments in the Changtan Reservoir of southeastern China from 1985 to 2015. ...

Abstract:
... Despite of the importance of understanding the sediment quality for lacustrine management, the source evaluation of sedimentary organic matter (SOM) in freshwater lakes is still insufficient. In this study, two shallow eutrophic lakes of Lake Taihu, China and Lake Izunuma, Japan were systematically investigated. Results of fatty acid profiles demonstrated that a wide range of organic matters, vary ...

Abstract:
... Healthy plankton communities are the foundation of many freshwater food webs. Their biodiversity is often used to directly reflect the health of the rivers. Globally, river ecosystem restoration is a critical issue and many freshwater ecosystems, especially in cities, are degraded because of intensive human activities. This is true for Jinan, China’s first pilot city for the Water Ecological Civil ...

Abstract:
... It is essential to understand the combined effects of elevated CO₂ and temperature on phytoplankton-zooplankton link when attempting to predict climate change responses of freshwater ecosystems. Phytoplankton species differ in stoichiometric and fatty acids composition, and this may result in phytoplankton-mediated effect on zooplankton at elevated CO₂ and temperature. Beyond the isolated analysis ...

Number of these genes varied from less than a half of EGT-compatible genes to an overwhelming majority, and their presence was treated as an evidence of cryptic green plastid. We have performed such an analysis with a novel weighted approach on an extended dataset of diatom gen ...

Abstract:
... The processes underpinning the differences between Antarctic and sub-Antarctic ecological communities are still unclear.

However, with the rapid development of aquaculture, the frequent occurrence of Yesso scallop's high mortality in summer has led to huge production losses. In the present study, seawater samples were collected from Yesso scallop farming waters ...

Abstract:
... Based on diatom, aquatic pollen and non-pollen palynomorph (NPP), lake sediment microfacies, and X-ray fluorescence (XRF) analyses we define three main phases of lake basin development including a marshy phase (ca. 16,600–9400 cal. yr BP), lagoon phase (ca. 9400–5900 cal. yr BP) and freshwater lake phase (since ca. 5900 cal. yr BP). Marine influence on the lake system linked to global sea-level ri ...
