Document Summary
What is global change biology: rising co2 concentrations, climate change temperature, precipitation, land use change, heavy urbanization, feeding an exponentially growing population, etc. Increase in nutrients (i. e. biogeochemical cycles) that enter the water and destroys dissolved oxygen in water; detriment to species that live there. Temperatures are continuously increasing; we keep breaking heat records. High latitude regions change a lot faster than lower latitude (cid:396)egio(cid:374)s . Notice how there is not a uniform change in temperatures. In precipitation, there is no uniform change either; some regions get more wet while others get more dry. Types of shift/change: left: hotter, middle: more extremes, right: change of distribution. Lots of forests and grasslands get changed to farm/agricultural land: largest ecosystem in us: corn/soybean rotations, shows you the largest influence of humans. Distribution of landscape and the stages in land use. Note: not all parts of the world move linearly through these transitions.
