We are a diverse group of Biology faculty who use quantitative skills in our everyday research, and are interested in developing these skills for undergraduate, graduate and postgraduate training. Please see our QSG resource site (still under development) for primers, examples, wiki’s and blogs that cover a range of quantitative skills.
Area of research: Environmental impacts on aquatic communities and ecosystems
Quantitative Approaches: Analysis of variance—multifactor repeated measures ANOVA on experimental data; Ordination analyses—principal component analysis of zooplankton community data, redundancy analysis to relate environmental gradients to zooplankton community data.
Software: Statistica, JMP, Canoco, R
Area of research: Evolutionary genetics and organismal biology
Quantitative Approaches: Analysis of variance, quantitative genetics of life histories, heritability, generalized linear models
Software: JMP, R
Area of research: Aquatic ecology and paleolimnology
Quantitative Approaches: regression (GLM); multivariate techniques to assess and reconstruct environmental change from community data (e.g., regression and calibration (WA, ML, PLS, Neural Networks); unconstrained (e.g., PCA, CA, DCA, NMDS), constrained, and partial ordination techniques (e.g., RDA, CCA, variance partitioning); multivariate assessment of difference between groups (e.g., ANOSIM, SIMPER); clustering techniques
Software: CANOCO, Primer, R
Troy Day (Math & Stats. Cross-appointed to Biology)
