On May 18, 1980, Mount St. Helens experienced a major eruption that had devastating effects on the ocal ecosystem. Prior to the eruption, the mountain had a series of earthquakes and steam-venting episodes, causing an injection of magma at shallow depths of the mountain on the north side. This esulted in the north side of the mountain giving way, allowing lava and rock to explode northwards owards Spirit Lake and beyond. This leveled about 600 square kilometers (235 square miles) of fores (a) Identify and explain the type of succession that occurred after the eruption. (b) Describe what the community structure might look like one year after the eruption and today. (c) By 1989, the Mt. St. Helens ecosystem had started to really take off. Describe the species diversity the community. (d) Predict the Mt. St. Helens community after 2004. Justify your response.

SCIENCE, TECHNOLOGY, AND SOCIETY In many countries,irrigation is depleting aquifers to such an extent that landis subsiding, harvests are decreasing, and it is becomingnecessary to drill wells deeper. In many cases, the withdrawalof groundwater has now greatly surpassed the aquifers’ ratesof natural recharge. Discuss the possible consequences of thistrend. What can society and science do to help alleviate thisgrowing problem?

WRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?

Many people who want to reduce their ecological footprinthave focused on how much energy is expended (and howmany climate-warming greenhouse gases are emitted) intransporting food from its place of production to its place ofsale. The typical grocery store item is shipped by truck, air,and/or sea for many hundreds of miles before reaching theshelves, and this transport consumes oil. This concern over“food-miles” has helped drive the “locavore” movement tobuy and eat locally sourced food.However, food’s transport from producer to retailer, asmeasured by food-miles, is just one source of carbon emissionsin the overall process of producing and delivering food. In2008, environmental scientists Christopher Weber and H. ScottMathews conducted a thorough life-cycle analysis (p. 400) ofU.S. food production and delivery. By filling in the table below,you will get a better idea of how our dietary choices contribute toclimate change. After measuring mass, energy content, and dollar valuefor each…
