Exploring the complexities of sexuality, this book delves into the evolutionary logic behind diverse reproductive strategies across species, including courtship and mating behaviors. It examines the prevalence of sexual reproduction over asexual methods and poses intriguing questions about gamete types, hermaphroditism in plants and animals, and male competition for mates. By addressing various aspects of sexual reproduction, the book serves as a resource for biologists and anyone interested in the evolution of sexuality, fostering deeper understanding of these key issues.

Focusing on the environmental and health impacts of arsenic, this book explores its role as both a medicinal element and a significant pollutant, particularly in West Bengal. It delves into the bioaccumulation of arsenic and its potential to cause tissue and cellular damage, emphasizing the functional modifications it induces rather than just structural changes to proteins. Designed for undergraduate and postgraduate students, researchers, and the general public, it aims to enhance understanding of arsenic's cyto- and geno-toxicity.

Focusing on the heart's structure, types, development, and function across various vertebrate groups, this textbook serves undergraduate Zoology and Life Science students seeking a comprehensive understanding. It assumes a foundational knowledge of embryology, anatomy, and physiology, while offering insights into both vertebrates and invertebrates. By exploring developmental and anatomical perspectives, the text enhances comprehension of the heart's functional and evolutionary significance, making it a valuable resource for zoologists and enthusiasts interested in comparative anatomy.

The book offers an in-depth exploration of fertilization, focusing on the union of male and female gametes in sexually reproducing eukaryotes, particularly within five classes of vertebrates. It emphasizes both cytological and molecular perspectives, enhancing comprehension of the evolutionary significance of fertilization processes. Aimed at advanced undergraduates and beginning graduate students, it provides a comprehensive synthesis of modern views on fertilization, catering to those seeking a foundational understanding or pursuing research in reproductive biology.

Focusing on the cellular life cycle, this book offers a comprehensive synthesis of modern perspectives on Amitotic and Mitotic cell divisions, tailored for advanced undergraduates and beginning graduate students. It emphasizes molecular regulation primarily in eukaryotic systems, while also touching on prokaryotic aspects. By comparing cell division in both plant and animal systems, it enhances understanding of these processes. The text serves as a valuable resource for cytologists, geneticists, and biologists interested in the intricacies of cell division.

Die Untersuchung der Sexualität beleuchtet die komplexen Verhaltensweisen und biologischen Bedeutungen, die durch verschiedene Faktoren beeinflusst werden. Der Fokus liegt auf der weit verbreiteten sexuellen Fortpflanzung bei Wirbellosen und Wirbeltieren sowie den evolutionären Strategien der Balz und Paarung. Fragen zur Anzahl der Keimzellen, zur Hermaphroditismus und zu Geschlechterkonkurrenz werden aufgeworfen, um die nicht-reproduktiven Aspekte sexueller Beziehungen zu verstehen. Das Buch bietet eine fundierte Diskussion für Biologen und Interessierte, die sich mit der Evolution der Sexualität auseinandersetzen möchten.

Das Lehrbuch behandelt die Struktur, Typen, Entwicklung und Funktion des Herzens bei verschiedenen Wirbeltiergruppen und richtet sich an Zoologie- und Biowissenschaftsstudenten. Es setzt Grundkenntnisse in Embryologie, Anatomie und Physiologie voraus und beleuchtet sowohl evolutionäre als auch anatomische Aspekte des Herzens.

Dieses Werk behandelt den Befruchtungsprozess bei sexuell fortpflanzenden Eukaryoten, insbesondere bei Wirbeltieren. Es beleuchtet zytologische und molekulare Grundlagen und bietet eine umfassende Synthese moderner Ansichten für fortgeschrittene Studenten und Doktoranden in der Reproduktionsbiologie.
