A separate section of the journal, Molecular and developmental evolution, is devoted to experimental approaches to evolution and development.

It gives me great pleasure to bring out this experimental zoology volume for Zoology students. This volume is constructed as per the revised syllabus of Zoology Practical for B. Sc. First Year Students Based on Syllabus instructed by Swami Ramanand Teerth Marathwada University, Nanded Curriculum under CBCS for Faculty of Science & Technology Undergraduate (UG) Programme Annual Pattern. This experimental zoology volume covers the syllabus of B.SC. First Year Practical Paper- V -Practicals Based on Theory Paper-I, II, III and IV (Nonchordata, Chordata, Cell biology and developmental biology).

International Review of General and Experimental Zoology, Volume 4 discusses the epibranchial organs in lower teleostean fishes, an example of structural adaptation; the aging and regression in the colonial marine hydroid Campanularia flexuosa, with special reference to senescence in hydroids; and the structure and characteristics of avian egg shells. The text also describes tissue mast cell and wound healing; the quantitative aspects of neurohistology; and the concept of the rods and cones approach. The strong relationships between the feeding behavior of marine organisms and biological conditions expressed in evolutionary terms are also considered. Zoologists, physiologists, biochemists, and people involved in the study of fish and wildlife services will find the book invaluable.

This is a major new textbook that is intended to lead students away from purely descriptive zoology courses into an experimental approach that emphasizes asking and answering questions about nature. The book gives a panoramic view of vertebrate life, classification, ecology and behaviour. Section I of the book describes the major groups of vertebrates and their origins. The second section covers classification and its methodology. Section III describes the ecology of vertebrates from two standpoints: how individuals cope with environmental extremes, and principles of population and community ecology as illustrated by experiments carried out in the field. Section IV describes the geographic distribution of vertebrates. The fifth section discusses migration. Vertebrate behaviour is the subject of the final section and covers observations and the theories and experiments they have inspired.
