Population Ecology | PDF | Population | Ecology Ecology is the study of the interactions of living organisms with their environment. within the discipline of ecology, researchers work at four specific levels, sometimes discretely and sometimes with overlap. these levels are organism, population, community, and ecosystem. Populations can exhibit exponential, or multiplicative, growth, in which each each addition to the population expands the rate of population growth (more individuals mean more reproductive output), leading to a positive feedback loop. Allee effect is new in chapter 2. the chapters on population regulation (chapter 3) and life tables (chapter 4) use a variety of new and better examples comp. What you’ll learn to do: discuss the scope and study of population ecology imagine sailing down a river in a small motorboat on a weekend afternoon; the water is smooth and you are enjoying the warm sunshine and cool breeze when suddenly you are hit in the head by a 20 pound silver carp.

Consequences of recent advances in understanding of population dynamics has lead to almost universal (among ecologists) acceptance of the proposition that population growth is geared to population density. Populations are dynamic entities. their size and composition fluctuate in response to numerous factors, including seasonal and yearly changes in the environment, natural disasters such as forest fires and volcanic eruptions, and competition for resources between and within species.

At the population and community levels, ecologists explore, respectively, how a population of organisms changes over time and the ways in which that population interacts with other species in the community.
