Paleoecological and paleolimnological studies can provide a long-term perspective on changes in environmental and ecosystem processes. The sediments documented both direct and indirect impacts of climate change and human activities on aquatic ecosystems. The fossils of zooplankton remain and pigments in lake sediments can reflect community structure changes of primary producers and primary consumers. The authors reconstructed the zooplankton and algal community changes during the past 600 years using carapaces of A. tibetiana and resting eggs of D. tibetana and pigments from the sediments of Dagze Co, in the central Tibet Plateau. Using total nitrogen and total phosphorus reconstructed the nutrient changes. These results suggest that algal community structure and changes in production can be attributed to alterations in the zooplankton community, with important implications for Tibetan aquatic ecosystems.

File naming and required software

File name: Data is stored in the format XLS of table, named "Dagze Co zooplankton pigments and nutrients.xls ”。 There are three sheets, namely pigments, zooplankton remains and nutrients. The pigments contain 14 fields, age and 13 kind of pigments; zooplankton remains contains three fields,Age, the number of Artemia. tibetiana and Daphnia. tibetana. Nutriments contains three fields, Age, TP (total phosphorus) and TN (total nitrogen).
Data reading method: View and edit it by using Excel software in Microsoft office.
