Paperback. Condición: New. Print on Demand. This book presents a new theory of biological reproduction that does not rely on assumptions regarding germ plasm or other unprovable concepts. The author argues that the process of reproduction is a natural consequence of the aging process in organisms, and that reproductive cells arise from parts of the organism that have become isolated from the main body. This theory is supported by experimental evidence from a variety of organisms, including plants and animals. The book also discusses the implications of this theory for our understanding of sexual reproduction, asexual reproduction, and the evolution of life. The author's insights provide a new perspective on the fundamental processes of life and challenge conventional wisdom in biology.

Paperback. Condición: New. Print on Demand. This book explores the concept of ecological succession, focusing on the changes over time that occur in ponds and other water bodies, and how these affect the fish populations that inhabit them. The author examines in detail a series of ecologically distinct ponds, analysing the physical, biological, and chemical characteristics of each, as well as the species of fish found within them. Through this comparative study, the author identifies the key factors responsible for determining which species of fish are present in a given pond, namely the availability of food, the presence of breeding grounds, and competition from other species. This book provides valuable insights into the complex interplay between the environment and the organisms that inhabit it, showcasing how ecological processes shape the distribution and abundance of species over time. Understanding these dynamics is crucial for effective conservation and management of aquatic ecosystems.

Paperback. Condición: New. Print on Demand. This book analyzes sea urchin egg fertilization, focusing on cortical responses following sperm penetration. The author's examination of the sea urchin Echinarachnius parma reveals that the membrane protecting its egg forms as a wave that sweeps across the egg's surface after sperm entry, which counters the widely accepted theory that the membrane forms simultaneously across the egg's surface. Moreover, the author observes a gradient of susceptibility to sperm across the egg surface, challenging the view that the fertilization membrane is solely responsible for blocking polyspermy. These discoveries shed new light on cortical changes during fertilization, demonstrating their role in preventing polyspermy and initiating development. The author's research expands our knowledge of fertilization mechanisms and their implications for understanding early developmental processes.
