In this study, planktonic diatoms were sampled in Sinfong mangrove forest in Hsinchu County. A total of 65 genera and 136 species of diatoms were identified, among which 15 species of Nitzschia were the most diverse.

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 8 records.

2 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

Sinfong mangrove forest is located along the southern and northern riverbank of Sinfong River, Sinfong Township, Hsinchu County. It has an area of approximately 4.3 ha. In 2017, the Urban and Rural Development Branch, Construction and Planning Agency, Ministry of the Interior, announced the national status of the Sinfong Important Wetland, which mainly encompassed Sinfong mangrove forest within the Sinfong River basin.

Sampling Methods

During the sampling period, 500ml of water samples were collected from each sampling points and taken back to the laboratory for observation and identification.

Study Extent The two sampling points were St1 and St2. St1 was located within the mangrove forest and St2 was located by the riverbank of Sinfong River on the edge of the mangrove forest. Both sampling points were tidal sections.
Quality Control For diatom identification, a number of manuals were used (Taylor et al. 2007, Wu et al. 2011). Valid diatom taxon names were according to Guiry and Guiry (2022).

Method step description:

  1. Samples were collected from habitat.
  2. The samples were acid-wash treatment for identification.
  3. Photograph the samples with an electron microscope.
