BIO 468 Lecture Notes - Lecture 22: Acer Saccharum, Soil Type, Benzene
Document Summary
We should have stated how deep we were going to excavate. Also we should have said that we don"t care how much copper is there, we just want to figure out toxicity (much cheaper) Eastern hemlock/white pine/northern hardwoods forest in nova scotia. Sugar maple, birch, beech, red spruce, hemlock, white pine. Forest composition at any site is modified by local conditions. Soil type: site fertility (tendency for high fertility sites maintain high fertility sites and vice versa, drainage. Aspect (which way the soil is facing: disturbance history (legacy of disturbance) Problems occur if we remove nutrient capital, say from forest fire the nutrient availability is depleted so drastically the succession of the site can be altered. Altering the succession of the site is about overcoming barriers. If ground is burned repeatedly the soil switches stable state to a state called barren.
