A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in by the zoologist Robert T. Keystone species play a critical role in maintaining the structure of an ecological community , affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether.

This year I decided to change the way I teach the last unit of the year, which is ecology. Our textbook is really old, and not aligned to NGSS. This year, I wanted to start developing some phenomenon based lessons that start with interesting observations and build student understanding from those real-world observations. HHMI has some amazing ecology lessons, including lessons based on trophic cascades. Since students love otters, I started out with a question and an image of sea otters. And, what determines how large each population can grow? At first, we had a class discussion about otters, where students informed me that otters have a favorite rock, and we came up with ideas about what would determine how many otters could live in an area?

This course is an introduction to ecology and ecosystem dynamics using a systems thinking lens. Through a case study on Mozambique's Gorongosa National Park, learners will explore how scientists study ecosystems, and investigate the complex array of factors that inform management efforts. At the end of the course, learners will be able to grapple with real-world conservation questions, such as whether an ecosystem can recover from anthropogenic disruption and what role humans can, and should, play in that recovery. I really enjoyed taking this course. It gave me good knowledge base in ecology and conservation. The course is very well structured and is suitable for people with no prior knowledge in the topic.
