BIO-315 Ecological Principles and Field Methods introduces students to the principles of ecology and the practical methods used in the field, exploring theoretical topics in ecological systems at the population, community, and ecosystem level — including energy flow, biogeochemical cycles, and sustainability — while engaging in fieldwork using methodologies like transect sampling and quadrat analysis, alongside GIS and statistical software for data analysis.
Ecological theory at multiple scales
The course explores ecological systems at three distinct scales — population, community, and ecosystem — recognizing that ecological principles operate differently and interact across each of these levels.
Genuine field methods, not just theory
BIO-315 pairs ecological theory with real field methodology — transect sampling, quadrat analysis, GIS, and statistical software — reflecting that ecology as a science depends on rigorous, hands-on data collection and analysis, not theoretical understanding alone.

Worked example: theory guiding field method choice
- Theoretical concept: Species diversity varies across different habitat types within an ecosystem
- Field method application: Using quadrat analysis and transect sampling to actually measure and compare that diversity across sites
- Lesson: BIO-315 teaches that ecological theory and field method are inseparable — theory tells you what to measure, and field methods are how you actually measure it

Frequently asked questions
Ecological phenomena genuinely operate differently at each scale — population-level ecology examines a single species' dynamics, community-level ecology examines interactions among multiple species, and ecosystem-level ecology examines energy flow and nutrient cycling across the whole system — and a complete ecological understanding requires seeing how these scales connect and influence each other. BIO-315 covers all three because focusing on only one scale would miss genuinely important ecological dynamics that only appear when you consider multiple levels together.
Ecology is fundamentally an empirical science — ecological theories about population dynamics or community structure need to be tested and measured against real field data, not simply accepted on the basis of classroom explanation, and skills like transect sampling, quadrat analysis, and GIS mapping are the actual tools ecologists use to collect that real-world evidence. BIO-315 requires hands-on field methods because genuine ecological competency includes the ability to actually go out and measure ecological phenomena, not just understand the underlying theory conceptually.
