Document Summary
Climatic variation and salmon abundance: a case study. Hare and francis hypothesized that the abrupt shifts in salmon production were associated with long term climatic variation in the north pacific. Munta found good correspondence between the multi-decadal shifts in salmon production and changes in sea surface temperatures in the north pacific. The physical environment is the ultimate determinant of where organisms live, the resources that are available to them, and the rate at which their populations can grow. The physical environment includes climate, which consists of long term trends in temperature, wind and precipitation. Radiation from the sun ultimately drives the climate system as well as biological e production. The chemical environment, which includes salinity, acidity, and concentrations of gases in the atmosphere and dissolved in water. Soil is an important component of the physical environment because it is where microorganisms, plants and animals live. Concept 2. 1 climate is the most fundamental component of the physical environment.
