Overview: This is an advanced ecology course that is aimed at senior-level undergraduates. It
is designed to build on foundational lower level undergraduate ecology courses and allow the
undergraduates to begin shifting to the knowledge base and ways of thinking required in
graduate school. The class will examine forested biomes as integrated ecological systems,
compare similarities and differences among biomes in order to better understand general
ecological principles, and consider implications for place-based management.
The class will build on the sub-disciplines of population, community, and ecosystem ecology to
study “ecological systems”. Ecological systems encompass all levels of organizations and
integration of all or many sub-disciplines in ecology is necessary to understand and manage
them. The use of sub-disciplines in ecology has helped us simplify ecological systems and
improve understanding of components of the systems. An important step in ecology is putting
the pieces together to understand and manage integrated ecological systems.
We will approach the study of ecological systems by examining how they differ across the
globe and identify the overarching principles that govern these differences. Traditionally,
ecologists have studied one or a few ecological systems in depth and their understanding of
physiology, population dynamics, community interactions, ecosystem processes and human land
use was heavily influenced by those particular systems. New technology now allows us to know
in-depth the functioning of many types of ecological systems. Through comparison across
biomes, we can better understand the factors that govern ecological systems in particular
locations. The role of disturbance in driving biodiversity, for example, varies with soil fertility
and ecosystem productivity. Disturbance can reduce diversity in low productivity systems and
increase it in productive systems. Hence, the management of disturbance need differ among
ecosystems to achieve biodiversity objectives
Goals:
1. Integrate subdisciplines in ecology to understand “ecological systems”.
2. Better understand general ecological principles through comparison among biomes.
3. Draw on these principles to better tailor conservation and management strategies to
local places.

Course Structure:
 Lectures on key principles and geographic comparison
 Virtual field trips of global forest biomes
 Student lead active learning projects
Grading: Grading will be based on 3 exams (100 points each) and 9 student projects (20 points
each) for a total of 480 points.
Student Projects:
Anticipated Learning Outcomes:
1. Ecology Department majors will be able to synthesize among sub-disciples such as
animal behavior, population ecology, community ecology, and ecosystem ecology to
understand integrated ecological systems.
2. Students will better understand fundamental principles of ecology by examining how
these principles are manifest in the different terrestrial biomes of the world.
3. Students will be able to draw on these general principles and knowledge of terrestrial
biomes to better tailor conservation and management strategies to local ecosystems.
4. Students will transition from ways of thinking and ecological knowledge typical of
advanced undergraduate students to those expected for beginning graduate students.
5. Students will demonstrate outcomes 1-4 in three examinations and in a final written
project.
