Document Summary
Inductive reasoning - general conclusions from specific observations. Deductive reasoning - specific conclusions from general observations. Hypothesis - falsifiable, tentative answer that can be tested. Scientific method - process of trying to find evidence to disprove a hypothesis. Nature is variable, we need to take replicates and use statistics. Theory - broader than a hypothesis, supported by lots of evidence from data. Ecology - scientific study of the relationships between organisms and their environments. There is no such thing as a free lunch. Temperatures drop at larger latitudes because radiation spreads over a bigger area. Warmer air holds more water vapour, warmer air tends to rise. Biogeography - how organisms are distributed/dispersed, dispersal capacity. Residence time -> capacity of a reservoir to hold water. Pure water absorbs red wavelengths, organic material absorbs blue wavelengths. Lotic (rivers) cold, nutrient poor, high o2 at top. Warm, nutrient rich, low o2 at bottom. Peatlands (bogs) - low production, low o2.
