What you'll learn
- Turn an observed ecological pattern into a specific, answerable field question with competing hypotheses, distinguishing predictions and a justified scale of study.
- Design field studies and experiments with correct experimental units, replication, controls, randomization and blocking, avoid pseudoreplication, and use BACI designs and simulation-based power analysis.
- Plan fieldwork that meets permit, animal care, Indigenous partnership and data governance requirements in Canada or the United States, with a field safety plan and biosecurity protocol.
- Choose and apply simple random, stratified, systematic, cluster and adaptive sampling designs, allocate effort among strata, and select quadrat, transect and plotless methods suited to the organism.
- Estimate density from quadrat counts and from line- and point-transect distance sampling, diagnose clumping and correct counts for imperfect detection.
- Estimate abundance and detection probability with mark–recapture, removal, occupancy, N-mixture, spatial capture–recapture, camera trap and eDNA methods, and evaluate their assumptions.
- Measure field biodiversity with accumulation curves, incidence-based estimators, beta diversity partitions, functional and phylogenetic measures, bioacoustics and community science data.
- Measure vegetation structure, cover, woody basal area, soils, water, microclimate and phenology with standard, repeatable methods and calibrated observers.
- Analyse telemetry data to estimate home ranges, habitat selection and movement behaviour, and handle capture, welfare and location data responsibly.
- Quantify spatial autocorrelation and scale, compute landscape metrics, work correctly with coordinate systems and use remote sensing indices such as NDVI with field validation.
- Prepare tidy, documented data and analyse field data with generalized linear models, mixed models, model selection and ordination.
- Design long-term monitoring with adequate power, link it to adaptive management, share data following FAIR and Indigenous data principles, and write a complete field study proposal.
