A New Look at ISTA in Iowa

In early April of this year, plans of the Iowa Academy of Science to form a new section for Science Teachers within the Academy were presented to Betty Goettsch, president of the ISTA by Dr. Robert Yager, a representative of the executive council of Iowa Academy of Science. Dr. Yager suggested that the ISTA might be interested in considering the opportunity for affiliation in this new division

Surficial Geology, Soils, and Plant Zonation Ross Biological Area

Plant distribution is investigated with regard to geologic, geomorphic, and pedologic influences. Little is known about the soil-plant relationship of native species. This study attempts to develop a basic concept that the native plant zonation can be described in terms of the above three factors simply on the basis of routine field investigations. Further studies may then be designed to bring about a more quantitative understanding of the actual nutrient and moisture regimes under which certain native species will be most commonly found
