This lab is intended as an introduction to a plant systematics course. Students work in groups of two to apply what they have learned about plant structures to develop a character matrix based on a set of imaged herbarium specimens of several mystery species. After constructing a phylogeny with their character matrix, they compare their hypotheses between groups and discuss the differences and similarities.

Description

Intended Audience:

Undergraduates in their first plant systematics class. The module assumes that students have been introduced to concepts in tree reading, phylogenies, and character matricies.

Description:

This resource includes a mystery specimen pack where identifiers have been moved, a reference file for instructors, and lab instructions, and worksheet. The module can be adapted for the distance learning environment either through providing the materials online or printing the mystery specimen pack and worksheets for each student or student group.

 

Learning Objectives:

By the end of this module students will be able to: 

1. Evaluate morphological characters to construct a character matrix

2. Develop phylogenies using a character matrix and be able to read phylogenies

3. Identify disadvantages to developing phylogenies only using morphological characters

This project was funded in part by the Institute of Museum and Library Services (CAGML-247505-OMLS-21)
