Topic 3: Demecology – the ecology of populations The main idea: Note how mathematical models are used to examine variation in growth of a population. Lecture outline: 1. Statistic and dynamic characteristics of population. 2. Growth curves patterns: J-shaped curve and S-shaped curve 3. Population regulation: Density-dependent and density-independent factors. 4. Human population patterns: - Population numbers. - Demographic transition and structure - Population urbanization

The typical hydraulic regime and flow characteristics of each reservoir were other key factors considered during criteria development. The relationship between water quality‚ biomass accumulation‚ and hydraulic residence time (or retention time)‚ which is the average amount of time required to completely renew a reservoir’s water volume‚ was taken into account when establishing the chlorophyll a criteria. For example‚ reservoirs associated with “run-of-the-river” dams typically have small hydraulic
