Document Summary

Gphy102 lecture 26 systems and cycles of the biosphere. Talk about atmosphere, hydrosphere, lithosphere, starting in on biosphere (soil systems last week: biosphere is the interface between all the spheres. Want to understand how it works and the patterns of life on the planet. Objectives: understand energy and matter flows in ecosystems, examine ecosystem productivity, compare and contrast different biogeochemical cycles. Cycling of matter through biosphere and its linkage to the other spheres. Biogeography: focuses on the distribution of life on earth, identification and description of processes influencing patterns of distribution at varying scales. How spatial patterns arise over various scales of time and space: eg evolution, migration, dispersion, extinction. How distribution is affected by physical and biological environments: a group of organisms and the environment with which they interact. Boundaries tree line, where starts to change into different types of trees: all about scale. How you choose to look at things.
