Paperback. Condizione: New. Print on Demand. This book provides a comprehensive account of stonefly life histories in southern Colorado's Rio Conejos. Stoneflies are integral members of stream ecosystems, serving as biological indicators, fish food, and energy sources for many aquatic organisms. Despite the importance of stoneflies, only 5% of the over 575 North American species have been adequately studied. This book seeks to address this knowledge gap by presenting detailed life history information for 31 stoney species alongside environmental data collected over multiple years. The author's meticulous fieldwork, including monthly sampling, intensive summer observations, and laboratory rearing, provides critical insights into the growth, development, and emergence patterns of these insects. Moreover, this book explores the ecological interactions between cohabiting stonefly species and their role within the broader stream ecosystem. Through rigorous scientific investigation, this book enhances our understanding of stonefly life histories and their ecological significance, contributing to the overall comprehension of freshwater ecosystems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.

Paperback. Condizione: New. Print on Demand. This book presents the findings of extensive research into the genetic and taxonomic relationships within and between three closely related plant genera: Sphaeromeria, Artemisia, and Tanacetum. The author analyzes RAPD data from 238 randomly amplified polymorphic DNA markers obtained from 41 populations of 16 taxa. The study reveals distinct genetic differences among the genera, providing support for the established separation of Sphaeromeria and Tanacetum from Artemisia. Furthermore, the findings suggest a closer affiliation of Sphaeromeria with Artemisia than with Tanacetum. The book contributes valuable insights into the evolutionary history and genetic diversity of these plant groups, offering a deeper understanding of their relationships and classification within the broader context of the Anthemideae tribe.
