BIOL 150 Lecture Notes - Lecture 10: Climax Community, Rain Shadow, Sonoran Desert
Document Summary
Learning objectives: explain the difference between a biome and a biogeographic region, explain the implications of biogeographic regions on biodiversity, explain the species-latitude relationship, explain the factors leading to long-term climatic trends. Biosphere: sum total of all the places in which organisms live. Biome: a large region of land dominated by a large vegetational formation (climax vegetation) whose boundaries are determined by climate (different ecosystems can be part of the same biome i. e. desert can refer to the sonoran or sahara deserts ) The loss of large predators (apex consumers has caused widespread disruption of ecosystems. When we try to pick out anything by itself we find it hitched to everthing else in the universe. - john muir, Soil was more fertile and stable due to the decrease in herbivory. Climate: long-term trends in temp. , humidity, rain, wind, cloud cover . Factors that influence climate are not random distinct climate zones caused by:
