between organisms and the environment; the connectedness between living systems and non-living systems on the Earth is called ecology. The term “ecology” which was coined by Ernst Haeckel comes from the Greek root words oikos logos literally meaning “the study of household”. Haeckel was referring to the interactions within the house of nature and we have used the word ecology (translated from the German Oekologie or Ökologie) to describe complex systems of life both extant and extinct. These interactions

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

Janisse Ray wrote the book‚ "Ecology of a Cracker Childhood." In the story‚ the author describes how she grew up‚ the influences that her family history‚ culture‚ and nature had on her‚ and how she is an individual as well as part of a whole. The memory that I believe gives a very personal insight into the author’s identity details her mother’s down home‚ southern cooking and the imprints‚ that her cooking impressed on her.

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
