Zoology


Book Description

Excerpt from Zoology: A Textbook for College and University Students After using much of the subject matter as a mimeographed text, the author prepared the manuscript in its final form, and during three summers has availed himself of the aid of many specialists at the Marine Biological Laboratory, Woods Hole, Mass. Through the interest of various authorities who gave advance information about their work, certain chapters include material prior to the actual publication of the research discussed. Some of the most important features of the book are the logical arrangement of facts about the animals within a group, a statement of the chief characteristics at the beginning of the discussion, and a summary on the economic importance at the end of each section. The newer physiology has been introduced and a bibliography checked by experts in each field is given at the end of each chapter. Sources readily available have been selected and resumes chosen instead of the pioneer researches. Extensive discussions of Embry ology and Animal Behavior have been found undesirable since such studies cannot be comprehensively treated in an introductory course without excluding other fundamental subjects.

The Evolutionary Synthesis


Book Description

Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the "modern synthesis" of evolutionary biology and genetics come together to analyze that remarkable event. In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin's theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin's original theory--that evolutionary change is due to the combination of variation and selection--is as solid at the end of the twentieth century as it was in 1859.

Nautilus


Book Description

1. 1 Nautilus and Allonautilus: Two Decades of Progress W. Bruce Saunders Department of Geology Bryn Mawr College Bryn Mawr PA 19010 wsaunder@brynmawr. edu Neil H. Landman Division of Paleontology American Museum of Natural History New York, New York 10024 landman@amnh. org When Nautilus: Biology and Paleobiology of a Living Fossil was published in 1987, it marked a milestone in cross-disciplinary collaboration. More than half of the contributing authors (36/65) were paleontologists, many of whom were collaborating with neontological counterparts. Their interest in studying this reclusive, poorly known animal was being driven by a search for clues to the mode of life and natural history of the once dominant shelled cephalopods, through study of the sole surviving genus. At the same time, Nautilus offered an opportunity for neontologists to look at a fundamentally different, phylogenetically basal member of the extant Cephalopoda. It was a w- win situation, combining paleontological deep-time perspectives, old fashioned expeditionary zeal, traditional biological approaches and new techniques. The results were cross-fertilized investigations in such disparate fields as ecology, functional morphology, taphonomy, genetics, phylogeny, locomotive dynamics, etc. As one reviewer of the xxxvi Introduction xxxvii book noted, Nautilus had gone from being one of the least known to one of the best understood of living cephalopods.




Animals and Science Education


Book Description

This book discusses how we can inspire today’s youth to engage in challenging and productive discussions around the past, present and future role of animals in science education. Animals play a large role in the sciences and science education and yet they remain one of the least visible topics in the educational literature. This book is intended to cultivate research topics, conversations, and dispositions for the ethical use of animals in science and education. This book explores the vital role of animals with/in science education, specimens, protected species, and other associated issues with regards to the role of animals in science. Topics explored include ethical, curriculum and pedagogical dimensions, involving invertebrates, engineering solutions that contribute to ecosystems, the experiences of animals under our care, aesthetic and contemplative practices alongside science, school-based ethical dialogue, nature study for promoting inquiry and sustainability, the challenge of whether animals need to be used for science whatsoever, reconceptualizing museum specimens, cultivating socioscientific issues and epistemic practice, cultural integrity and citizen science, the care and nurturance of gender-balanced curriculum choices for science education, and theoretical conversations around cultivating critical thinking skills and ethical dispositions. The diverse authors in this book take on the logic of domination and symbolic violence embodied within the scientific enterprise that has systematically subjugated animals and nature, and emboldened the anthropocentric and exploitative expressions for the future role of animals. At a time when animals are getting excluded from classrooms (too dangerous! too many allergies! too dirty!), this book is an important counterpoint. Interacting with animals helps students develop empathy, learn to care for living things, engage with content. We need more animals in the science curriculum, not less.
