Chapter 56.3, Problem 2R
Summary Introduction
To review:
Beavers are considered an ecosystem engineering species and a keystone species, but not a foundation species.
Introduction:
An ecosystem engineering species is a species that influences and modifies its habitat in a significant way. A keystone species is a species, which plays an important role in its community, irrespective of its size or abundance. A foundation species is a species, which has a great impact on its community due to its large size or abundance.

Make a presentation using the ecosystem to show the interrelationship of animals and plants. It should be in a flowchart that hilights biodiversity and interdependence, when on species is removed the rest are in jeopardy.
Explain the following:
Importance of butterflies within an ecosystem
Importance of butterflies to humans
how humans negatively affect the biodiversity of butterfliesHow change, large and small, has an effect on the ecosystem
There are several hypotheses to explain why biodiversity is higher near the equator. State one of these hypotheses, and make an argument AGAINST it being the correct explanation.

Expand on these points individually, based on your species’ unique story. Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.)

Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forwardafects small mammai populations.

The fire is contained and burns out and the chemical spill is cleaned up. Monitoring of the plant community following this disturbance researchers noticed that after the spill and fire there was a sharp drop in species diversity, abundance, and richness. Over the next 5 years the area was monitored. The community's diversity, abundance, and richness all increased slightly during the first year however after the first year only the abundance went up during the following 4 years with no changes in any other area.
