ที่มา:KASETSART UNIVERSITY FISHERIES RESEARCH BULLETINหัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Composition and Distribution of Zooplankton in the Pasak Jolasid Reservoir, Lop Buri Province) ผู้เขียน:Issarapon Jithlang, นางลัดดา วงศ์รัตน์, ศาสตราจารย์ สื่อสิ่งพิมพ์:pdf AbstractComposition and distribution of zooplankton in the Pasak Jolasid reservoir were studied during 2002. Samples were horizontally, obliquely and vertically drawn at two-month intervals using three mesh sizes plankton nets (22,40 and 100 um). A total of 119 species of zooplankton was recorded. Rotifera was the most diverse zooplankton group in this reservoir. The taxa found in decreasing order were as follow: Phylum Rotifera (24 genera, 76 species and 4 varieties), Phylum Protozoa (13 genera and 22 species), Phylum Arthropoda (12 genera, 20 species and 1 group), and Phylum Cnidaria (1 genus, 1 species). An occurrence of the freshwater jellyfish (Craspedacusta sinensis) was the first record in the reservoir of Thailand. Spatial and temporal variations in species number of zooplankton were relatively small; variation in number of species raning between 44 and 89. High numbers were recorded in October at one station along Pasak river ranging between 70 and 89 species, while low numbers ranging between 44-54 were recorded in April at two stations located on the bank of the reservoir. |
ที่มา:KASETSART UNIVERSITY FISHERIES RESEARCH BULLETINหัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Zooplankton of Kanchanaburi Province, Thailand) ผู้เขียน:นางลัดดา วงศ์รัตน์, ศาสตราจารย์, วรรณดา พิพัฒน์เจริญชัย สื่อสิ่งพิมพ์:pdf AbstractThe freshwater zooplankton of 5 types of water body in the western part of Thailand was studied for twelve months. Twenty-one species of Protozoa, eighty-eight species of Rotifera, twenty-eight species of Cladocera, two species of Calanoida and two species of Cyclopoida were found in samples collected monthly in 1998. In general, Rotifera dominated in all water-bodies, although fluctuations occurred during the year. Sampies from the reservoir heavily vegetated yield the highest number of species. The following species are common Thai zooplankton: Arcella bathysoma, A. vulgaris, Centropyxis aculeata, Difflugia lebes, D. urceolata, Euglypha fi I if era, Anuraeopsis fissa, Brachionus angularis, B. falcatus, Filinia longiseta, Keratella cochlearis, K. tropica, Lecane bulla, L. papuana, Polyarthra vulgaris, Trichocerca similis, Ceriodaphnia cornuta, Bosminopsis deitersi, Diaphanosoma excisum and Moina micrura. A tropical rare species, Daphnia lumholzi, was found in rivers, reservoirs and man-made lake in this study. Copepoda was a minor component in the study area where Thermocyclops crassus was common throughout the year. One calanoid copepod, Phyllodiaptomus sasikumari found in a richfield is the first record in Thailand. Seasonal variation of species composition might not be so pronounced, however number of species at most sampling locations increased during wet season. |
