Relationships between chironomids and water depth in Bosten Lake, **njiang, northwest China
A significant relationship between the distribution and abundance of chironomids and water depth has long been recognized. Few studies on this topic, however, have been carried out in arid regions where the ch...

Comprehensive evaluation of heavy metal contamination in surface and core sediments of Taihu Lake, the third largest freshwater lake in China
The spatial and temporal variations of Fe, K, Co, V, Cr, Cu, Ni, Zn, and Pb were determined in the sediments of Taihu Lake, the third largest freshwater lake in China and categorized into natural origin (Fe, K...

Alternate trajectories in historic trophic change from two lakes in the same catchment, Huayang Basin, middle reach of Yangtze River, China
In order to assess how best to manage impacted lake systems, one needs to understand the trophic functioning of the lake system and the recent states through which the lake may have transitioned. Lakes in the ...

Environmental changes during the past 13500 cal. a BP deduced from lacustrine sediment records of Lake Qinghai, China
A 475-cm long sediment core (QH-2005) from Lake Qinghai was used to carry out multi-proxy analysis of δ18O and body length of ostracod valves and redness and grain size of sediments, in order to reconstruct envir...

Limnological responses to warming on the **zang Plateau, Tibet, over the past 200 years
Paleolimnological analyses can be used to evaluate limnological responses to changing climate over decadal to centennial timescales, especially in regions with sparse lake monitoring data. We used a training s...

A geochemical record of recent anthropogenic nutrient loading and enhanced productivity in Lake Nansihu, China
Total organic carbon (TOC), total nitrogen (TN), stable carbon and nitrogen isotopes (δ13C, δ15N), total phosphorus (TP) and organic phosphorus (OP) were measured in surface sediments and two short cores (DU-3 an...

Holocene climate reconstructions of Ulungur Lake (**njiang, China) inferred from ostracod species assemblages and stable isotopes
In this paper, the data on the paleoclimatic and paleoenvironmental changes during the Holocene are presented and a discussion is made on a 225-cm-long sediment core from Ulungur Lake, located in Northwest Chi...

A chironomid-based salinity inference model from lakes on the Tibetan Plateau
Previous studies have shown chironomids to be excellent indicators of environmental change and training sets have been developed in order to allow these changes to be reconstructed quantitatively from subfossi...

Weak chemical weathering during the Little Ice Age recorded by lake sediments
Low magnetic susceptibility, low Sr content and hence high Rb/Sr ratio in the lake sediment sequence indicate a weak chemical weathering process under arid and cold climate of the Little Ice Age in a single cl...
