Available in PDF, EPUB and Kindle. Book excerpt: Diatoms comprise the major group of algae in Iowa waters. Their ecological significance, important in pollution evaluation studies, cannot be fully appreciated without a thorough knowledge of their taxonomy. A scale for abundance rating was used giving at least a rough estimate if data permitted. The names of 50 diatom genera occurring in Iowa are listed and for each genus, the number of taxa in the master list and the number in the 'more common' list are presented. A pollen analysis is tabulated; the samples in this analysis extended through 35 ft. of sediment to the postglacial interface at Little Miller's Bay, Lake West Okoboji. Dating was conducted by the radiocarbon technique for samples taken between 34 ft. and 35 ft. in the sediment core. Since this level had the maximum spruce pollen concentration and the pollen percentage decreased progressively above this level, it was considered as the postglacial interface. Some interesting problems lie in consideration of those diatoms which have disappeared from the original lake flora and those which have become common only since the middle of the postglacial period.

Book excerpt: Diatoms are single-celled plants sometimes ranked as a division, sometimes as a class within a division of the plant world. Remarkable both for the large number of species and for the variety of habitats in which they exist, diatoms have attracted attention recently as indicators of environmental conditions. This book provides a general survey of the diatoms of the interior waters (thus excluding Lake Michigan and the border rivers) and selected subaerial habitats (soils, growths on tree trunks, damp spots) of Illinois. It features identification keys, descriptions of species, distribution maps, and a generous supply of illustrations. The work thoroughly documents current knowledge of diatoms and provides a tool for botanists who wish to carry the work further.

Available in PDF, EPUB and Kindle. Book excerpt: In this volume twenty-three species of Neidium are described. Sample materials were collected in the Zoig� Wetland, an expansive network of lakes and wetlands located in Sichuan Province, China. From the total number of Neidium species reported, sixteen of them are described as new. 281 light microscope and scanning electron microscope photographs document all taxa and illustrate the morphology of these Neidium species. Detailed descriptions for each species are given and the species are compared with other, similar species from other regions of the world. The variability in valve morphology in the genus, including presence and distribution of renilimbi, longitudinal canals, central nodule and striation, are documented. A comprehensive table with morphometric details of all described Neidium species rounds up the volume. This survey of Neidium species almost doubles the number of new Neidium taxa described from China and is of interest for all readers working on diatoms and Bacillariophyceae.
