Multivariate Ecological Community Analysis II

Take your multivariate analysis skills to the next level by building upon the professional understanding and capability attained in MECA I.  This course takes you through the defensible ten-step process for performing, interpreting, and communicating defensible analyses for the most widely used free ordination techniques (PCA, NMS, NMS Scores), classification procedures (Cluster Analysis, TWCA), group testing tools (MRPP, PerMANOVA, SumF, ISA), association assessments (Mantel Test, Compare Scores), and trait analyses (functional diversity metrics, FCA).  Plus, the strengths and weaknesses of other commonly encountered tools (e.g., RA, DCA, TWINSPAN, PCoA, dbRDA) are explored, tips are given on how to apply and interpret graphing tools to ordination diagrams, and the procedure for bootstrapping multivariate analyses is outlined.

Learn at your your own pace with or without instructor support (see Online Course Format Chart below for details).

MECA I.  If taking the PREMIUM version for the professional certificate program, and you have previously taken Jeri Peck’s MECA I course or “Multivariate Data Analysis, Using PC‑ORD” short-course, or Bruce McCune’s “Community Structure and Analysis” course, you can request to take the MECA I final exam to test out of this prerequisite for a fee.

• Learn on your own and at your own pace over the 3-month term as you watch 37 prerecorded lectures, read up on the covered topics in the required textbook (see below), and watch and perform 19 practice exercises using the PC-ORD software.  After each lesson, take a brief knowledge-check quiz before moving on.

• Required Textbook (covers MECA I & II):  Peck, J.E.  2016.  Multivariate Analysis for Ecologists:  Step-by-Step, second edition. https://www.wildblueberrymedia.net/store/step-by-step

• Required Software (covers MECA I & II):  PC-ORD version 7, which was written by and for ecologists applying multivariate analyses.  A discounted purchase price for a perpetual license has been negotiated for our students. https://www.wildblueberrymedia.net/store/pc-ord-7-single-user-license-student-user

LEARNING OBJECTIVES

After taking this course, students will be able to:

• Choose among PCA and NMS to address analysis objectives
