Some remarks on long-term and seasonal changes in the zooplankton of Parakrama Samudrae to low water levels following a catastrophic cyclone in 1978. Species composition seems to have returned to a stable condition after restoration of high water levels. Seasonal changes in composition and densities of plankton were not marked over a three-years sampling period.作者: Gnrh670 時(shí)間: 2025-3-23 07:52

Thermal stratification, mixis, and advective currents in the Parakrama Samudra Reservoir, Sri Lanka. The data were used to calculate Birgean mechanical work (Birge 1916) and derived values. Although similar temperature ranges were recorded (28.0°–34.5° C) for August/September 1979 and March 1980, fluctuations in mixing work (Eckel 1948) (up to 4 J m.and 20 J m., respectively) were observed, which作者: 單獨(dú) 時(shí)間: 2025-3-28 10:53 作者: Chandelier 時(shí)間: 2025-3-28 17:26 作者: 擦試不掉 時(shí)間: 2025-3-28 21:10 作者: surmount 時(shí)間: 2025-3-29 00:19
