The seasonal variation and enrichment of nutrients, pigments, bacteria, fungi and algae in the surface microlayer and subsurface waters were investigated in three ponds at the University of Wisconsin-Milwaukee Field Station, Saukville, Ozaukee County, Wisconsin. Samples were collected intermittently from June, 1978 through October, 1981. Microlayer samples were collected using a glass plate and a screen sampler. All ponds showed dramatic seasonal variations in nutrients, microorganisms and algae in both surface and subsurface waters. The data indicate that physical factors such as adsubble processes, antirain and atmospheric deposition, along with biological factors such as heterotrophic mineralization and autotrophic uptake, play …

The reliability of direction finding, as stated in the old adage-"moss grows best on the north sides of trees"-is subject to various interpretations. A personal evaluation of the reliability of this adage was attempted in a study of the corticolous cryptogams (non-seed plants which grow on the bark of trees) at The University of Wisconsin-Milwaukee Cedar-Sauk Field Station and adjacent Cedarburg Bog. In this study the trees were inspected not only for the presence of the true mosses but also for algae, fungi, lichens and liverworts. The results summarized in this report are based on observations of over 2000 separate …

Tucked away in the bogs and swamps of Wisconsin, and in similar habitats throughout the world, thrive a myriad of unicellular plants known as Desmids. They are among the most aesthetic of all microorganisms and vie with the glassywalled Diatoms as "Jewel Plants." If it were not for the inquisitive biologist and the students of the microscopic cosmos, Desmids well might exist unnoticed. For although they have highly intriguing biological features they play no role in water spoilage problems, nor are they important in the food cycle of aquatic animals. Hence they do not attract attention nor invite the condemnations …
