Chapter 38, Problem 12TYK
SCIENTIFIC THINKING The human-generated increase in greenhouse gases is a natural experiment (see Module 38.11) that provides many opportunities to study the effects of warming temperatures and climate change on populations, communities, and ecosystems. For example, snowshoe hares are adapted to the climate of their habitat in the taiga of the high mountains and northern regions of North America. One prominent adaptation is seasonal changes in fur color—a white winter coat that turns brown in the spring—that camouflage hares from a long list of predators, including lynx, bobcats, martens, weasels, foxes, owls, hawks, mountain lions, wolves, and coyotes. These color changes are triggered by day length. As increasing spring temperatures cause earlier snowmelt in the taiga, biologists have observed many white hares sitting on brown earth. Suggest how this natural experiment could be used to investigate the effects of climate change on populations and communities in the taiga ecosystem (assume historical data are available).

Question:
Think and research the effects of humans' buildings structures, communities, etc. on undeveloped land. Particularly, look at natural species in Texas, as well as the physical environment.
We learned an ironic twist to the story of global warming while watching the film: Ice and Brimstone: Years of Living Dangerously. What was it?
a. That an increase in erupting volcanoes was another extreme weather event.
b. That running wind mills pollutes more than coal plants.
c. That oil refineries were one of the largest contributors to research in clean energy.
d. That melting ice in the arctic was revealing new deposits of coal to be mined.
Misconception: Humans can’t negatively impact ecosystems, because species will just evolve what they need to survive.

Body size of mammals also correlates well with latitude (Bergmann’s rule); the larger pumas live at high latitudes. Consequently, this variation in body size has been interpreted as the result of selection for efficient temperature regulation. Why are homeothermic animals often larger at high latitudes?arrow_forward
