Study Notes
Course Information
- Course: BIOB50H3F Ecology
- Term: Fall 2024
Instructor
- Dr. Péter Molnár
- MSc: Mathematics, University of Munich
- PhD: Mathematical & Statistical Ecology, Climate Change Impacts on Polar Bears, University of Alberta
- Postdoctoral Fellow: Disease Ecology, Global Change Ecology, Conservation Biology, Climate Change Impacts on Parasitism & Disease, Princeton University
Laboratory of Quantitative Global Change Ecology
- Focuses on how climate change, land use, and other disturbances affect ecological and epidemiological interactions
- Examples include:
- How does climate change affect polar bears?
- How does climate change alter the spread of parasitic diseases?
- How does land use change affect interactions between mammal populations and their parasites (e.g., via disease spillovers)?
Learning Goals
- Become familiar with fundamental ecological principles and concepts across all ecological levels (individual, populations, communities, ecosystems)
- Learn classical ecological studies and results.
- Interpret different types of ecological data (theoretical, observational, experimental, modeling).
- Formulate and test ecological hypotheses in different contexts
- Apply, analyze, and interpret basic ecological models for individual, population, and community dynamics
- Use spreadsheet programs to implement and evaluate population and community dynamics models
- Apply ecological principles to understand applied aspects of ecology, such as disease ecology, climate change impacts, and approaches to conservation biology
What is Ecology?
- The study of relationships between organisms and their environment. This includes all conditions of existence.
- Sources of ecological knowledge include:
- Traditional ecological knowledge
- Local ecological knowledge
- Writings describing animal and plant relationships (e.g., by Aristotle)
- Advances by naturalists in the 17th-19th centuries (e.g., Linnaeus, Humboldt, Darwin)
An Example of Ecological Interactions (Marine Trophic Cascade)
- Sea otter populations declined in the late 20th century, possibly due to increased predation by orcas.
- Sea otters' decline also impacted kelp forests, leading to urchin barrens.
An Example of Ecological Interactions (Schistosomiasis)
- Schistosomiasis (snail fever, bilharzia): caused by parasitic flatworms called schistosomes
- Can lead to significant health issues like urinary and/or intestinal infections, abdominal pain, diarrhea and bloody stool, leading to conditions like liver damage, kidney failure, infertility, or bladder cancer.
Everything in Nature is Interconnected
- Organisms within ecosystems are connected via resource needs.
- Creating complex interaction webs (illustrated by diagrams of food webs).
Ecology in the Anthropocene
- Human impact has significantly changed Earth's history.
- Actions have led to rapid and substantial ecological changes in many areas including increasing population, increasing carbon dioxide emissions, changing methane atmospheric concentration, reducing tropical forests, increasing nitrogen flux to coastal zones, increasing ocean acidification
- Ecologists are facing challenges that include, understanding the impact of climate change, land use changes, overexploitation, invasive species and ecosystem homogenization and species extinctions.
Learning Approaches to Ecology
- Observation and Natural History
- Experimental Ecology & Null Hypothesis Testing
- Multiple Hypothesis Testing with Best-Fit Comparisons
- Ecological Modelling
