Document Summary
Lecture 13: species ranges and limiting factors; climate: eeb pursues the why questions, mouse and blender demo: csb studies can be conducted even after death, eeb studies. Levels of whole organisms and up cannot because it focuses on why questions. Less concerned with biological model species: more concerned with differences among species, how they came to be, and what they imply. Temperature varies through a gradient starting from poles microhabitat scale: everything is patchy at every scale! Species have ranges of tolerance along environmental gradients: bell curve graph demonstrates performance of a species varies along gradient. Low intensity end to high intensity end; middle hump where species does best under its optimal conditions: aspects of performance, reproduction. Individual survival: marginal extremes on either ends of the curve. Lethal zones at the ends survival is impossible: death zone on mount everest o2 concentration (1/3 of sea level)
