Summary: This study investigates the existence of paleolakes in the isolated watersheds of the Mojave Desert, confirming their presence and the active nature of basin margins. The research shows that evidence of past high-lake stands is often buried but preserved by geomorphic processes, and suggests that the basin margin is where evidence of pluvial lakes should be sought. Some Holocene paleolakes in the Ivanpah basin seem to have persisted for decades to centuries.

Summary: This study investigated the role of DSi in Tonle Sap Lake, Cambodia. The concentration of DSi was higher in the dry season than in the wet season, and both measurements were comparable with lakes in other parts of the world. The molar ratio of TN:TP:DSi suggested limitation of TP and DSi in both seasons, and phytoplankton biomass was found to be influenced by DSi, TN:TP, dissolved oxygen, and water temperature.

Summary: Lake Barrine on the Atherton Tablelands in tropical northeast Australia provides a sediment record of hydroclimate and vegetation change over the past 18,000 years. The research reveals distinct periods of intense but seasonal rainfall and a trend towards wetter conditions during the early Holocene, leading to the establishment of tropical forests in the catchment. The precipitation changes in Lake Barrine correspond to other records in the region and are influenced by the intertropical convergence zone, the Indian Ocean Dipole, and the El Nino Southern Oscillation.

Summary: Hydrological regimes and climatic factors have complex influences on plant phenology in floodplain wetlands. Warmer temperature tends to advance the start of the pre-flooding growing season, while flood regimes play a dominant role in determining the phenology in the post-flooding growing season. Carex phenology is more affected by hydrology in high-elevation areas compared to low-elevation areas. These findings provide insights for the conservation and management of floodplain wetlands in the Yangtze River.

Summary: Eutrophication has significantly impacted biotic communities, posing a major threat to biodiversity conservation in lake ecosystems. This study examines the long-term diversity dynamics in response to nutrient enrichment among lakes in different ecological states, based on diatom records from eight shallow lakes in central China. The findings reveal distinct trends in diversity dynamics, including replacement of resident species by pollution-tolerant species in heavily-polluted lakes, net species gain at an accelerating rate in transitional lakes, and a slowdown in species gain in macrophyte-dominated lakes. It highlights the importance of considering both individual lake and regional factors in conserving diatom diversity.

Summary: This study explores the patterns and driving forces of diatom diversity in Sphagnum peatlands in central and northeastern China. It was found that diatoms are more prevalent in these peatlands than previously thought. The distance-decay rate of diatom community similarity is faster in central China, likely due to strong dispersal limitation in these enclosed montane peatlands. The diatom composition in these peatlands is primarily determined by niche-based processes.

Summary: Human activities are causing significant changes in the global biogeochemical cycles of nitrogen (N), phosphorus (P), and biogenic silica (BSi). This study investigates the burial rates and ratios of N, P, and BSi in sediment cores from eight lakes in the middle Yangtze River floodplain to understand nutrient dynamics in response to human disturbances. The results show that the burial rates of N, P, and BSi have increased since the early 20th century, with a hiatus in the 1970s. The ratios of N:P, N:BSi, and P:BSi suggest changes in nutrient sources and agricultural land expansion as factors influencing nutrient burial in the lakes.
