Document Summary

Study of interactions between organisms and environ. Goal is to determine biological / physical factors that determine distribution & abundance of species. Science / conservation biology uses principles of ecology. Can help predict state of environ. (ex: extrapolation) Eaten by mice and deer (good host for adult ticks) Ticks suck blood takes lyme bacteria. Deer approaches us, tick latches onto us. Correlation between: tick population and acorn falling. All comes down to densities of acorns, mice and deer (and ticks) Change of properties of organisms that span more than 1 gen. Physical environ. affect how species adapts and evolves. Past attributes of species affect present characteristics of species and which are present in a habitat + influences ecological role of species. There are pdf versions of reduced chapters. Discussion = fourth lecture, exams take place here, mandatory. 1. 9 mil eukaryotic (non-bacterial) species (chapman 2009) More sampling yields more species, but at diminishing rate.
