The RF−NPA (Rice Field Non–Pesticide Application) and RF−PA are located in Phimai District, Nakhon Ratchasima Province, Northeastern Thailand. These two rice fields (15°10′55.1″N, 102°23′46.7″E (RF–NPA), and 15°10′45.0″N, 102°23′46.1″E (RF–PA)) are located 146 m above sea level. This resource contains 33 occurrence records of 16 zooplankton species.

|タイトル||Viability of zooplankton resting eggs in rice field sediment after pesticide applications|
|ファンデイング||This research was funded by Research and Graduate Studies Khon Kaen University and the Human Resource Development in Science Project (Science Achievement Scholarship of Thailand, SAST).|
|Study Area Description||RF−NPA (Rice Field Non–Pesticide Application) is 1.76 ha in size, had not received any pesticides during the year preceding the study. RF−PA (Rice Field–Pesticide Application) is 2.08 ha in size and had pesticides applied during the sampling year. Both rice fields are located in Ban Non Lukki, Than Lalot Subdistrict, Phimai District, Nakhon Ratchasima Province, Northeastern Thailand. These two rice fields (15°10′55.1″N, 102°23′46.7″E (RF–NPA), and 15°10′45.0″N, 102°23′46.1″E (RF–PA)) are located 146 m above sea level. The distance of RF−NPA is only about 55 m at its closest point to RF−PA. Both RF–NPA and RF–PA were rain-fed rice farming by direct sowing.|
|研究の意図、目的、背景など（デザイン）||The goal of this project was to database occurrences of zooplankton species hatching from two rice field sediments.|
Sediment samples were collected from two rice fields in Phimai District, Nakhon Ratchasima Province, Northeastern Thailand. The hatching experiment was conducted for 30 days. All zooplankton samples were identified and counted under a compound light microscope. The occurrence of zooplankton in each rice field was recorded.
|Study Extent||All zooplankton species were recorded on 30 May 2019 based on hatching resting eggs collected from RF–NPA and RF–PA, Phimai District, Nakhon Ratchasima Province, Thailand.|
|Quality Control||Identification to species level focused on rotifers and cladocerans following the identification keys of Segers (1995), Smirnov (1996), Nogrady and Segers (2002), and research papers (e.g., Sinev (2016). Other identification references were provided in the dataset.|
Method step description:
- 1. Sediment samples were collected from RF–NPA and RF–PA on 14 October 2018. 2. The hatching experiment was conducted from 26 April 2019 to 20 May 2019. 3. All zooplankton species were documented and their locations were recorded. 4. Scientific names of zooplankton were validated.
