Collection of small mammals in the island and peninsula region of western Lake Erie from 1962 to 1967 has provided information on the present distribution of several species. The white-footed mouse (Peromyscus leucopus ...

Histological and histochemical tests give similar results for the midguts of Floridobolus penneri (Causey, 1957) and Narceus gordanus (Chamberlin, 1943). The peritrophic membrane is composed of basic proteins and acid ...

Microscopic examination of biogenic opal isolated from the 0.05-0.02-mm total mineral fraction of 12 upland soil profiles indicates that fragments of sponge spicules are minor but ubiquitous constituents of Ohio soils, ...
