The most interesting result was the decrease of abundance and biomass, proceeding from the sea mouth (about 6000 ind m.) towards the innermost part of the lagoon (less than 100 ind. m.). Correlations are suggested with the different grain size of the sediment.作者: penance 時間: 2025-3-22 04:39 作者: animated 時間: 2025-3-22 08:47 作者: EWER 時間: 2025-3-22 15:46 作者: lobster 時間: 2025-3-22 19:13 作者: 使聲音降低 時間: 2025-3-22 21:30

Age, stage and size structure as population state variables for , (Oligochaeta, Tubificidae)e results are used to establish a size-stage structured matrix population model. The asymptotic behaviour of the model is studied and a basic sensitivity analysis is performed, to evaluate the effects of the observed variability of the matrix elements, on the eventual finite growth rate.作者: 有花 時間: 2025-3-23 14:07
Energy budget of Oligochaeta and its relationship with the primary production of Lake Sevan, Armeniaoduction of the preceding 10 years, which enables a prediction of the quantitative indices of the community of Oligochaeta. The values of energy budget ratios depend on temperature and oxygen regimes but not on the trophic status of the reservoir and were comparatively stable during the observed period.作者: FIR 時間: 2025-3-23 19:44

The effect of water movement on the distribution of Oligochaeta in lakesf‘ sapropel’, can also be limiting to the distribution of oligochaetes. Organic contamination in conditions of low water dynamics can result in the absence of Oligochaeta through oxygen depletion. Dynamic water movement can stimulate the mass development of Oligochaeta in organically polluted areas.作者: 分開如此和諧 時間: 2025-3-27 00:35 作者: Jingoism 時間: 2025-3-27 02:45 作者: Priapism 時間: 2025-3-27 07:04 作者: micturition 時間: 2025-3-27 10:58 作者: infantile 時間: 2025-3-27 15:02 作者: 有害處 時間: 2025-3-27 18:48 作者: 心神不寧 時間: 2025-3-28 00:31 作者: paltry 時間: 2025-3-28 05:33
