BIOL 412 Lecture 4: Lecture 4 - Climate & Geography
Document Summary
What is your prediction on plant community similarity from east to west vs. north to south of bc? similarity in north to south range. West to east wet then dry then wet rainfall between north to south is similar environmental conditions are similar; some differences but not very much. But from vancouver to osoyoos different precipitation so more dissimilarity. -- distance decay if we draw a distance decay graph, the n-s graph has a decrease in similarity but shallow line/slope. Similar but much different system. (more difference) even though they are similar in terms of precipitation, there"s still significant different flora community. Wind storms pacific northwest windstorms have big impact in the area: blowdown events windstorm so strong that it knocks down trees and affect the community. Creates openings for invasive species to move in the areas. Hurricanes small islands can be wiped clean by storm surges creating laboratory for studying island recolonization: eg.
