Paperback. Condición: New. Print on Demand. This book is an illustrated account of a detailed study of the fauna of Mayfields Cave, a small cavern in southern Indiana, United States. The author spent months observing the animal inhabitants of the cave in all conditions to which they are normally subjected. The author observed and identified a multitude of species within the cave, including beetles, myriapods, spiders, crustaceans, and even blind fish and bats. The author collected data on the habits of each species, and in some cases was able to determine the role of the species in the cave ecosystem. This book also discusses the conditions that favor or hinder cave life, and includes information on the origin of cave life. This book provides readers with new insights into the lives of cave animals, and sheds light on the intriguing world that exists beneath our feet. 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. Condición: New. Print on Demand. This book presents the findings of a study conducted by the author over eight years, during which they bred and reared generations of Cladocera, small planktonic crustaceans, to conduct selection experiments on a physiological character: light sensitivity. The author carefully controlled the environment and stimuli to which the Cladocera were exposed, selecting individuals based on their reaction times to light and isolating their descendants into separate strains. Through this process, they aimed to isolate a strain more responsive to light and another with reduced responsiveness. The study contributes valuable insights into the nature and heritability of physiological traits within a pure line, challenging the prevailing view that selection within a pure line was ineffective. The experiments yielded strains with significantly different reaction times to light, demonstrating the potential for selection to modify physiological characteristics. This book provides a detailed account of the experimental methods, data analysis, and the author's interpretation of the results, offering valuable information for biologists interested in the genetics and evolution of physiological traits.
