Some Optimal Growth Media For Use In The Botany Classroom, Marshall D. Sundberg
Journal of the Minnesota Academy of Science
Cultures of various bacteria and fungi are often used in introductory botany classes. In most cases the students are simply asked to examine these colonies or to prepare a microscope slide. Directions are given in this paper for the preparation of optimal growth media which may be consumed by the student. This provides a new twist to otherwise routine laboratory exercises.

Cluster analysis of data from 277 Braun-Blanquet releves differentiates 11 major forested communities in a 1,450 sq km area of northeastern Minnesota. Upland communities include black spruce-jack pine, jack pine, red pine, aspen-birch, aspen-birch-fir, and mixed conifer-deciduous. Forested wetland communities include black spruce, tamarack, cedar, ash, and alder carr. The greatest floristic differences are between those communities at opposite extremes of the moisture spectrum, and greatest similarities between red pine and aspen-birch-fir communities. Floristic similarities and differences are-reflected by the positions of communities in the synecological ·moisture nutrient field Structural differences between upland communities are more notable than floristic differences.
