IER specializes in statistical design and analyses of terrestrial and aquatic ecosystems including:
- Biological hypothesis driven mark-recapture and survival analysis to test hypothesis regarding factors affecting fish and wildlife population size, trend, and demography using information theoretic model selection methods.
- Spatially explicit mark-recapture methods to provide robust estimates of density , optimized sampling designs, and assess factors affecting broader scale distribution in sampled areas.
- Habitat selection and occupancy models to determine resources most selected by wildlife species and assess trends in occupancy of habitats.
- Survey design, stratification, and allocation of effort to optimize precision based on budgetary and logistical limitations.
- Distance sampling and combination distance sampling-mark-recapture methods.
- Analyses of covariance that allow testing of research or management hypotheses while controlling for other extraneous factors.
- Data-driven population viability analysis to evaluate conservation and research strategies for bird and mammal species. Stochastic modelling to assess the effect of variation on model predictions.
- Power analyses based on pilot data or retrospective analyses.
- Design and analyses of water quality & sediment monitoring projects.
- Comparisons of macroinvertebrate communities to regional reference conditions
- Before-After Control-Impact (BACI) Studies for robust estimation of impacts or perturbations.
- Multivariate statistical techniques, such as principal component analysis, canonical correspondence, step-wise regressions, and other approaches.
- Piecewise regression methods to estimate ecological thresholds.
