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. In this exert‚ Ray describes her mothers cooking. My mother was

So far Love’s belief—that hermeneutical close readings‚ due to their implied humanism‚ may produce a depth that is neither inherent‚ nor necessary to a text—has been expounded‚ along with her affinity for sociological practices of close observation and description. To this‚ I would like to add her own account‚ from a talk given at the University of Pennsylvania‚ of the way Goffman’s work has informed her own. She says: […] in his work on social interaction and communication‚ Goffman focused consistently

Importance of Deep Reading Both of these texts lead to the theory that the Internet‚ over time‚ may rewire our brains so that we are less capable of sustained attention and deep thought. They explain how the young brain needs years to develop skills such as: deductive reasoning‚ analogical skills‚ critical analysis‚ reflection‚ and insight. This pivotal dimension of time is potentially endangered by the digital culture’s pervasive emphasis on immediacy and information loading that embraces speed

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
