Survey of Plankton Diatoms in Nanren Lake

Latest version published by Taiwan Endemic Species Research Institute on Jun 24, 2019 Taiwan Endemic Species Research Institute

This study surveyed the plankton diatoms in Nanren Lake, Kenting National Park, Pingtung County, Taiwan. A total of 29 species of 21 genera were identified, and most species belonged to the Eunotia and Nitzschia genera. However, Aulacoseira granulata and Discostella stelligera were the dominant species.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 3 records. 1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Geographic Coverage

Located in the Nanren Mountain Ecological Protection Area in the northeastern part of Kenting National Park, Nanren Lake comprises three permanent lakes: the Central Water Body, Independent Nanren Lake, and Yilan Lake (or Ancient Nanren Lake). The natural freshwater lake is formed of rainwater and spring water and is the largest static ecological water system in Nanren Lake.

Sampling Methods

Plankton diatoms collection was performed on January 18, 2018. The sampling sites were the Ancient Nanren Lake (St1), west side of the main lake (St2), and east side of the main lake (St3), as illustrated in Fig. 1. From each site, 500 mL of lake water was collected and transported to the laboratory for observation and species identification.

Study Extent Nanren Lake is located in the Nanren Mountain Ecological Protection Area in northeastern Kenting National Park on the east coast of the Hengchun Peninsula. The geographic position is 22°50’N and 120°50’E. The altitude of the nearby Nanren Mountain to the west of Nanren Lake is 479 m, categorized as low-altitude highland. The Central Water Body of Nanren Lake was originally paddy fields and wetlands. Local residents moved away because of the hardship of making a living there. In 1982, the only outlet of the water body, Hongtu Stream, became clogged, and water stagnated to form the current Nanren Lake. According to a survey conducted in 1990, the area of the lake at that time was 22.54 ha

Method step description:

  1. All the diatom fluids were first concentrated in a centrifugal machine for 10 minutes at 3,500 rpm; the fresh diatoms were then observed using a differential interference contrast microscope. Subsequently, acid washing was conducted using concentrated sulfuric acid, after which observation and identification processes were performed using an electron microscope.
