Some Aleutian Islands are surrounded by urchin barrens while others are surrounded by kelp forests. Which statement gives the primary explanation for these differences? O The kelp forest islands experience a substantially warmer climate than do the urchin barren islands. Grazing by urchins prevents the formation of kelp forests. Kelp forest islands and urchin barren islands differ with respect to oceanic currents. O Kelp eat urchins, thus preventing their establishment.

Increasing levels of carbon in the atmosphere have been linked to changes in the global climate patterns. You will be asked about this in the next questions. We also talked about more direct impacts of higher atmospheric carbon levels on living systems (I included them in the Nutrients - Bioshpere lecture). Describe one non-global climate change (something that does not involve a change in temperatures or rainfall) impact on the ecology of living systems and how increasing carbon levels in the atmosphere cause this impact.
The mountain pine beetle inhabits western North America, where it feeds on the inner bark of pine trees. In recent years, the beetles expanded hundreds of km north, because winters are warmer. Their eggs are kill ed by extreme cold events, which no longer occur Rising temperatures have also stressed the trees, making them more vulnerable to mountain pine beetle mortality. The mortality trees is now so extensive that the forests are projected to become a net carbon source instead of a carbon sink, releasing 200 megatons of carbon per year by the year 2020. The response of mountain pine beetles to warmer temperatures can be described as: () acclimation adaptation O radiative forcing range shift phenological shift

Why are deserts typically found at 30° N and S in latitude? Group of answer choices Hadley Cells cause dry air to descend at 30° N and S in latitude. Rain shadows are only found at 30° N and S in latitude. All deserts experience a continental climate, which are common at 30° N and S in latitude. Savannas are found at 30° N and S in latitude, not deserts.
