Researchers in Alaska conducted an artificial soil warming experiment to examine how a warming arctic might affect the nitrogen cycle. The active layer of the soils (that is, soils not frozen all year) were either not heated throughout the growing season (control), or warmed 3 degrees C throughout the growing season (soil warming). The study ran for 5 years, from 2013 to 2017. Which of the following statements is not supported by the data provided? the soils must contain some source of immobilized nitrogen if detectable mineralization rates are occurring the difference in nitrogen mineralization rates between warmed soils and control soils increased through time O If climate change leads to warming in the arctic, it would be expected to increase nitrogen mineralization rates over broad areas over the course of the study, denitrification rates will be higher in control soils compared to warmed soils warmed soils exhibited higher nitrogen mineralization rates than control soils

Figure 1.16 seems at first to be simply a description of thephysical and chemical properties of a lake. Outline how livingorganisms participate in determining the physical and chemical(i.e., temperature and O2) patterns. Consider organisms livingboth in the lake and on the land surrounding the lake. Consideralso a research report that shows that dense populations of algaesometimes change the temperature structure of lakes by raisingthe thermocline and thereby increasing the thickness of the deep,cold layer; how could algal populations do this, and what couldbe the consequences for deep-water animals?
