Mass extinction events are directly and indirectly responsible for what the Earth looks like today in terms of both organismal composition and distribution; it is estimated that well over 99% of organisms that once existed on Earth have gone extinct. These events have occurred several times during the past 500 million years, with varying causes, intensities, and lasting impact. We will examine each mass extinction in detail, including the current putative “6th Extinction”, evaluating and discussing the cause, effect, and lasting impact of each. Special focus will be paid to the Permian, K-Pg, and Holocene extinctions due to their magnitude and recency.
In this course, we will cover the basic and advanced concepts related to vaccines and immunizations and how the immune system mounts responses to vaccines to establish protective immunity. We will discuss the different ways society views vaccines, paying attention to the current anti-vaccination movement, and how social media has impacted the spread of anti-vaccine propaganda. Importantly, we will investigate strategies on how to promote vaccination as an important tool to protect our society against disease. To obtain a deeper understanding of concepts and controversies related to vaccines, we will investigate the current pandemic, emerging epidemics and the future of vaccines.

"Wildlife" is defined as wild birds and wild mammals. It does not include other vertebrates (fish, amphibians, or reptiles), nor does it include invertebrate animals. This is a course about the Principles of Wildlife Conservation, and is not specifically about wildlife management, or even wildlife ecology. However, both these latter subjects will be examined briefly. Wildlife conservation usually involves as much if not more of the following disciplines than it involves biology: history, sociology, and politics. It is recommended that you have taken a course in ecology and statistics before enrolling in this course.
