Bio Wk 5 Models, Restoring Ecosystems, and Change in Climate

• Human land-use practices may result in soil salinity

  • Deforestation, Irrigation of shallow-rooted crops
• Osmoregulation - Regulating Water
• Neolithic revolution - The shift from hunting and gathering to agricultural practices
• Describe the effects of a poorly managed soil system - change the water cycle, reduce the amount of nutrients in the soil, increase pollution, increase soil salinity, and it makes the soil more prone to erosion
• Tillage practices - preserve or improve soil structure
• Crop rotation - alternating different types of plants on the same piece of land
• human-induced selection pressures - Human activities that exert selective pressure on species traits
• Pollution contributes to human-induced selection pressures on species -  It can poison or disrupt the reproductive systems of species
