1. Preparation Stage 1) Define the research topic and key study objectives. 2) Conduct a literature review by gathering relevant theoretical knowledge from books and reliable online sources. Specific references include the "Urban Lichen Detective" book and previous studies on lichen biodiversity. 3) Establish research objectives aligned with the GLOBE measurement protocols. 4) Determine sample collection points within the study area, specifying latitude and longitude coordinates for both the starting and ending points. 2. Data Collection Stage 1) Conduct team meetings to plan and coordinate research activities. 2) Survey the study area and finalize sampling locations. 3) Measure key environmental factors using GLOBE protocols: - Sampling Points Selection: Identify sample collection sites along the designated nature trail within the study area. - Temperature Measurement: Use a digital hygrometer to measure air temperature at the bark surface, recording data three times per sample. - Relative Humidity Measurement: Use a digital hygrometer to assess air humidity at the bark surface, collecting data three times per sample. - Light Intensity Measurement: Use a soil moisture pH light meter to measure light intensity at each sample site. - Data Entry: Record all collected data into the GLOBE Data Entry system.
This research, "A Study of Plankton Biodiversity in the Water Resources of Sa Nae Daeng Pond, Somdet Phra Srinagarindra 95 Public Park (Khao Pae Choi), Na Ta Luang Subdistrict, Mueang Trang District, Trang Province," aims to investigate the biodiversity of plankton in the water resources of Sa Nae Daeng Pond. The study examines water temperature, pH, dissolved oxygen (DO), cloud types, relative humidity, and air temperature. The water quality study of Sa Nae Daeng Pond revealed an average water pH of 8, an average water temperature of 28.25°C, a dissolved oxygen (DO) range of 5.25 mg/l, and an average water transparency of 0.32 m. The average air temperature was 32.8°C, the average humidity was 51.95%, and the most prevalent cloud type was Cirrus, followed by Cumulus. The plankton biodiversity study identified 10 species of zooplankton, including Dugesia spp., Ephemeroporus barroisi, Rotifer sp., Paramecium sp., Spirulina sp., Neidium productum, Phacus sp., Strongyloides stercoralis, Oscillatoria sp., and Odonata sp. Three species of phytoplankton were identified : Micrasterias furcata, Closterium sp., and Arcella discoides Ehr. Keywords: Somdet Phra Srinagarindra 95 Public Park (Khao Pae Choi), Na Ta Luang Subdistrict, Mueang Trang District, Trang Province, plankton, water quality, Sa Nae Daeng Pond.
