Q: Field experiments demonstrate that variation in soil fertility influences terrestrial primary production
Field experiments demonstrate that variation in soil fertility influences terrestrial primary production. However, we cannot say that nutrients exert primary control. That role is still attributed to...
See AnswerQ: Review figure 18.2, in which Rosenzweig (1968)
Review figure 18.2, in which Rosenzweig (1968) plotted the relationship between actual evapotranspiration and net primary production. How do you think that decomposition rates change across the same e...
See AnswerQ: Why was precipitation alone, without temperature, sufficient to account for
Why was precipitation alone, without temperature, sufficient to account for most of the variation in grassland net primary production across central North America (see fig. 18.3)? Figure...
See AnswerQ: How are the desert dune ecosystem and the arctic and alpine tundra
How are the desert dune ecosystem and the arctic and alpine tundra ecosystems indicated in figure 18.2 the same? Figure 18.2:
See AnswerQ: How would actual evapotranspiration and net primary production in the desert dune
How would actual evapotranspiration and net primary production in the desert dune ecosystem, which is a hot desert, and the arctic and alpine tundra ecosystems likely respond to a significant increase...
