Meeting Time:          W 4:10-6:00pm                     

Office Hours:           Wednesday 1-2 or by appointment

Textbook:                 Required:

An Introduction to Methods and Models in Ecology, Evolution, and Conservation Biology by Braude and Low

Community Ecology: Analytical Methods Using R and Excel (Data in the Wild) by Gardener

Prerequisites:         undergraduate or graduate level coursework in ecology, evolution and or conservation biology.



This class will focus on a critical understanding of major global threats to biodiversity. We will also dedicate considerable time to introducing students to the analytical tools and methods necessary to critically evaluate competing demands for limited conservation resources. Upon completion of this course students will have an understanding of the historical roots of conservation issues as well as being able to develop quantitative and culturally appropriate approaches to addressing these issues.


Midterm 20%

Group Project 30%

Quantitative assignments 15%

Historical Essay 10%

Debate 15%

Reading Discussion 10%

For each lecture exam you will be responsible for all reading material and all lecture materials. The final exam is comprehensive, but will be weighted for material after the mid-semester exam. If you have a conflict with exams contact me as soon as possible and arrangements will be made to take the exam prior to the scheduled date. There are no make-ups for missing an exam unless you have a valid preapproved excuse or medical emergency etc.

This class will consist of one weekly lectures and discussions of the literature. Each week a student will have to lead at least one class discussion concerning the readings. This will occur during the last half hour of class and the leader should be prepared to keep the conversation running for that length of time. To facilitate this the discussion leader will have thoroughly read all the papers and be prepared to ask questions that draw linkages across the topics not simply summarizing the papers. Students may lead the discussion in a traditional question and answer format, or through more active techniques. They will be graded on the following criteria: 1) understanding of individual papers (40%) 2) synthesis across papers and with the lecture topic (40%) 3) ability to foster student engagement (20%). For each discussion I will choose one older paper and it will be up to the discussion leader to choose a more recent (2015-2017) paper about that week’s topic. Students much email me the paper one week before their discussion so that everyone has a chance to read it. I expect every student to have read each of the assigned papers for each class. Failure to do so will not only hurt your own education, but will lower the your grade.

Student participation:

Everyone in this class should feel comfortable to express an idea, even if the idea is not a popular one. I encourage intellectual controversy and believe it is how we learn best. We expect all students to abide by their respective school’ code of academic integrity GSAS: Breaches of the student code such as cheating and plagiarism (that is, taking credit for the work of others) will not be tolerated, and any breaches of the student code will be referred to the Dean’s Office. Students seeking disability services must register here, and I will be happy to accommodate their recommendations.


Conservation Biology Exercises:


Class work: This class has an emphasis on active learning, thus you will have homework due every week (including the first week) and most times this homework will transition into group work within class. Thus if you do not do the homework ahead of time you will most likely be lost within class, and that you will bring down your group. It is in everyone’s best interest for you to do the homework and come to class prepared to discuss and engage with the material.

Recitation: One of the main goals of this class will be to give you a suite of quantitative skills to help assess biodiversity and the threats facing it. While this could take many different forms, I am grounding this class in community ecology theory. The second half of the class will have several assignments to teach you both quantitative community ecology but also how to use these tools within the free statistical environment, R. However as this class is only two hours long, we will not be able to do much of this within the lecture, thus we will have a weekly two-hour voluntary discussion where your group can meet with the TA to work through the problem sets.



We will be having one class long debate centered on the question “Are Species or Ecosystems the most appropriate scale for conservation” To prepare for this each student must read an article supporting one of the two views and submit that paper to me one week in advance. I will curate these papers on the course website so that everyone can see what resources are being brought to the debate.

The debate will consist of two teams, which I will assign. Each team will have to make a 10 min opening statement (and may use up to three total slides). Each team should plan on making use of at least three resources during their opening statement. Each team will also have a chance to make a rebuttal to the opening statement.

Then the debate will move into a less formal format where we will allow a give and take between the sides and the participants. Each student is expected to make a substantive comment backed up by the paper that they chose to read, and at least one more extemporaneous comment. Extra points will be allocated for students who can work in other resources from class and who are able to respond to critiques of their statements in a professional fashion.

Group Project:

Students will work in groups of three or four individuals will complete one of several group projects. The point of these projects is to understand the complexity of real-world conservation issues and to present the views of the varying stakeholders while coming up with practical solutions that are both ecologically grounded but also socially just. Some of these projects are in-class designs that I created, but I have also reached out to conservation practitioners and they may have projects for you to work on with real world applicability. Additionally one or more of the projects may involve working with partners in different institutions.

Potential projects may include those suggested by the Wildlife Conservation Society, The Royal Society for the Protection of Birds, or Birdlife International.

Historical Essay:

You will have a short essay on the history of an idea due February 1st. The goal here is to see how an idea developed over time, as outlined in B&L chapter 22. Therefore I want you to choose one of these papers and follow not only how the idea has developed since publication, but also dive back to see what the ideas intellectual antecedents were like (there’s an example in B&L if you need more clarification).  The papers are:

You’ll have to choose this paper before the first class and be prepared to say which paper and why during class. The assignment itself will be a 1500-2000 word essay (excluding references, of which I suspect there will be a substantial amount) outlining where this idea came from and where it went after publication.
