We learned about keystone species and trophic cascades. Discuss keystone species and trophic cascades by describing how the re-introduction of wolves, a keystone species in the Yellowstone Park ecosystem, drove a trophic cascade, starting with elk, that led to the restoration of the Yellowstone National Park ecosystem.  In your discussion, describe how the absence of wolves affected elk, that, in turn, affected rivers and streams, and how the re-introduction of wolves rehabilitated rivers and streams that led to the restoration of the Yellowstone National Park ecosystem.

An effective way of conserving biodiversity is through enacting legislation to protect biodiversity.  What was enacted in 1973 to identify,  protect, and develop a management plan to bring back at-risk species to sustainable numbers?

Discuss what we learned about melanoma and health care equity gaps in the diagnosis and treatment of melanoma in underrepresented communities from our in-person lecture and Canvas discussion assignment.  In your answer, describe what melanoma is, include a misconception about melanoma, and an example of a health care equity gap in melanoma diagnosis and treatment, how this equity gap affects underrepresented communities, and what patients and health professionals can do to close this health care equity gap to increase the diagnosis and survival of patients from underrepresented communities.

We recently experienced the San Bernardino Line Fire this semester. We also learned about climate change from our student group presentations. Use the knowledge you gained from our student group presentations to discuss a human activity that causes climate change, and the connection of climate change to the San Bernardino Line fire. In addition, draw on your experience and from the our student presentations to describe the consequences of the San Bernardino Line Fire, and what we can do to prevent climate change leading to wild fires.
