Tropical Ecology & Conservation Course Info
Winter Term 2 – 2021
In
this course we will explore fundamental ecological and evolutionary
principles using tropical landscapes as our geographic template. We
will assess the factors that make tropical systems both unique but also
vulnerable to degradation, drawing from comparisons across geographic
regions. While we learn about the structure, function and biological
history of the tropics, we will address the myriad challenges these
regions face in biodiversity loss and conservation practice.
This course is best suited for 3rd and 4th year students with a basic
background in ecology, evolution and geography. Each week, we will
introduce a course theme with a lecture, to provide a sound conceptual
foundation, followed by discussion based on studies in the primary
literature. Students are expected to read, evaluate and discuss
scientific literature relevant to these course topics.

Learning Outcomes in this Course:
Upon successful completion of this course, students will be able to:
1. Apply principles of ecology to understand the structure and function of tropical ecosystems.
2. Understand the fundamental ecological,
evolutionary and biogeographic processes that influence patterns of
diversity
within the tropics, historically and contemporarily.
3. Assess the anthropogenic threats to tropical
systems and the conservation initiatives for biodiversity protection.
4. Read and evaluate scientific literature and
provide critical reviews and commentary of published studies.
5. Use available data from published studies to test
hypotheses generated through discussion of conceptual ideas in tropical
ecology and conservation.
6. Integrate findings from research of scientific
literature into a written and oral review of a tropical ecosystem and

1. Intellectual Contributions & Participation: Peer
evaluation and feedback is central to scientific investigation,
particularly in the development and refinement of ideas and written
projects, reports or assessments. The lectures and the tutorials of
this course are geared to allow you to ask questions, explore ideas,
constructively criticize, and seek out answers through further
investigation and inquiry. This full participation is expected in
class. Intellectual contributions, including participation in class and
in group discussions, will help you to gain confidence in articulating
ideas in front of an audience and in assimilating and making inferences
from information in scientific papers. Marking will be based on the
guidelines outlined in the rubric for participation shown below.
Addresses learning objectives 1-4
2. Assignments (journal article discussion and reports): We
will read and discuss papers published in the primary literature, which
relate directly to the major themes explored in the course. During
discussion days, assigned groups will provide a brief overview of the
paper, followed by a seminar-style discussion. Students should come to
class having read the paper, with at least three of their own questions
to facilitate discussion. Following discussion students will submit
short assignment answering posted questions or problems developed in
the discussion. Students can work on ‘Discussion Report’ assignments in
groups. See the marking rubric below for a breakdown of the assessment
criteria. Addresses learning objectives 1-5
3. Group Presentation: As part
of the final research project, students will assemble a presentation
that highlights each of the main components of their review and
synthesis (see below). The aim of the presentation exercise is to help
students verbally formalize their outlined projects as they write the
first complete drafts of their paper. Presenters are offered feedback
from their student peers, to evaluate the depth and quality of content
for each section of their project, or to identify potential gaps and
areas for improvement. The group component of this assignment
encourages idea sharing and evaluation of alternative ideas in the
design and composition of the oral (and written) project, including the
importance of maintaining a supportive environment for group
contributions, an important skill for scientific collaboration.
Presentations will be assessed following the rubric shown below.
Addresses learning objectives 4-6
4. Final Research Paper - Review & Synthesis: You
will choose a tropical locality to research in a review and synthesis
article, following the manuscript style of the journal Trends in
Ecology and Evolution. In your assessment, you will assimilate
information on four components that describe this region: biological
diversity, historical biogeography, anthropogenic threats and
conservation strategies. This report is designed to be similar to a
“Rapid Assessment” style composition, using data and information
gathered from published sources and primary scientific literature.
Students submit drafts of their research paper to be exchanged for
peer-review, with feedback from the teaching team, prior to the final
submission. This assessment is centered on developing research and
critical thinking skills, as well as sound writing, information
assimilation and critique. See the marking rubric below for a breakdown
of the assessment criteria. Addresses learning objectives 1-6
Goals and learning outcomes by Topic:
Below is a list of the themes we will touch on in this course using lecture and discussion
(the order of these topics might be switched)
Climate, diversity of communities and classification:
Understand how climates vary across the globe and the factors that
determine these patterns – use this to explain why tropical forests are
found where they are.
Describe the diversity of ecosystems within the tropics and identify
unique features of different tropical environments across the globe
(what are the differences between tropical dry and wet forests, or
within tropical montane regions).
Historical biogeography:
Review major geological events and their potential impacts on biodiversity patterns (e.g., continental drift, mountain building
Understand how such events have generated a diversity of ecosystems within the tropics
Community structure and trophic structure:
Understand how tropical forests are structured and how this may promote diversity
Explore the complexity of tropical systems based on species
interactions and unique relationships – start to reflect on how such
interactions can generate and lead to higher diversity in the tropics
Species interactions:
Review the kinds of species interaction there are, and understand how
this relates to concepts such as niche partitioning and negative
density dependence.
Explore some of the interactions that are especially well developed or
unique to the tropics (plant-pollinator interactions and networks,
frugivory, including seed shadows and animal dispersal)
Biodiversity patterns:
Understand the different spatial components of diversity and how they
are quantified and interpreted (including alpha, beta and gamma
diversity)
Explore how these different aspects of diversity contribute to the latitudinal gradient in diversity
Consider variation in diversity across tropical systems – why are some
areas more or less diverse than others within the tropics?
Rarity in the tropics:
Identify the different forms of rarity in numerical abundance and
distribution on multiple scales, explore the consequences of
correlations of rarity (in topics of extinction risk)
Understand what endemism is and where endemics species are concentrated
Consider these metrics in developing priorities for conservation.
Maintenance of diversity:
Understand and evaluate different hypotheses that may maintain local
diversity in tropical communities (including Janzen – Connell effects,
negative density dependence)
Discuss the fragility or stability of mutualistic relationships in the
tropics, and explore the spectrum of biotic interactions in tropical
systems that may influence diversity
Evaluate patterns of niche partitioning in tropical systems and the
evidence that this mechanisms maintains diversity in the tropics
Functional Tropics – productivity and biomass:
Understand what productivity is and how it can be measured
Become familiar with some of the major factors affecting nutrient
cycling in the tropics and some of the key players (e.g., Mycorrhizae,
roles of Phosphorus, overview of ‘leaf economics’)
Coevolution in the tropics:
Explore some of the complex biotic interactions that make tropical systems unique
(e.g., fig-wasp systems, leafcutter ant societies, specialized frugivory and seed dispersal)
Discuss how these relationships can influence evolutionary patterns, and how this can in turn influence tropical diversity
Origins of diversity:
Assess rates of speciation and extinction across latitudes, and explore
the evidence for how this may contribute to the diversity of tropical
systems.
Explore how the high diversity of the tropics relates to geological
periods of time. Discuss how regional or continental-level factors
might be important for the origins of diversity in the tropics (e.g.,
patterns of drift, mountain building, refugia and isolation).
Extinction and species loss:
Step through different threats to tropical forests (e.g.,
deforestation, invasive species, bushmeat, pathogens), and how these
vary across geopolitical boundaries and geographic regions. Explore
this using different case studies.
Evaluate threats to tropical systems with climate change. What are the
forecasts (and uncertainty surrounding predictions) for species loss
and how tropical communities will respond to climate change?
Discuss synergistic effects of climate change and anthropogenic pressures on tropical systems.
Sustainable use in the tropics:
Explore different ecosystem services in the tropics and their local, regional and global implications.
Investigate REDD and PES programs and their potential successes and pitfalls
Successes in tropical conservation:
Discuss cases of restoration or rehabilitation for tropical systems
Review the history of protected areas in the tropics, including their
establishment and maintenance, and the cases that have generated
successful (or unsuccessful) conservation practice.
