In winter the chemical composition of epiphyton and epipelon was similar. In summer the epiphyton had on a unit weight basis more organic matter and carbonate, and had per unit organic matter a higher algal number, 作者: GUEER 時間: 2025-3-22 19:45 作者: HPA533 時間: 2025-3-22 23:08

Contribution of photosynthetic sulphur bacteria to primary production in Lake Vechtenf total daily productivity in the pelagial zone. The percentage of photosynthetic bacterial production of total annual planktonic primary production calculated for the entire pelagial zone, taking into account compensation for decreasing volume of lower strata, was 3.6% (i.e. 127 against a total production of 3 510 kg C.lake.yr.).作者: 生氣地 時間: 2025-3-23 14:35
Macro-invertebrate communities associated with the macrophytes of Lake Vechten: structural and functution depended strongly on colonizable plant surface area and vegetation density. The macrofaunal communities of the . and . stands contributed mainly to the lake’s carbon cycle. Being poorly represented by herbivores, the macro-invertebrate communities will affect the lake’s primary production only slightly.作者: 都相信我的話 時間: 2025-3-23 18:36
The aquatic macrophytes of Lake Vechten. Species composition, spatial distribution and production to increasing water turbidity, increasing tree-shading and, from 1978 onwards, grazing and trampling by cattle..Production rates, derived from different combinations of measurement and calculation, were compared. The macrophytes contributed only about 7% to the total lake production in 1980.作者: 泥沼 時間: 2025-3-24 01:42 作者: filicide 時間: 2025-3-24 02:59
The phytoplankton species composition and the seasonal periodicity in Lake Vechten from 1956 to 1979e data of 1975–1979 are compared with those from earlier records, distinct changes can be observed. These changes are discussed with reference to the trophic status of the lake. The vertical distribution of some species is described.作者: Strength 時間: 2025-3-24 08:04

Zone routing uses bordercasting, while contact-based schemes select out-of-zone contact nodes to avoid bordercasting.
