Download or read book Landscapes and Labscapes written by Robert E. Kohler and published by University of Chicago Press. This book was released on 2010-11-15 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is it like to do field biology in a world that exalts experiments and laboratories? How have field biologists assimilated laboratory values and practices, and crafted an exact, quantitative science without losing their naturalist souls? In Landscapes and Labscapes, Robert E. Kohler explores the people, places, and practices of field biology in the United States from the 1890s to the 1950s. He takes readers into the fields and forests where field biologists learned to count and measure nature and to read the imperfect records of "nature's experiments." He shows how field researchers use nature's particularities to develop "practices of place" that achieve in nature what laboratory researchers can only do with simplified experiments. Using historical frontiers as models, Kohler shows how biologists created vigorous new border sciences of ecology and evolutionary biology.

Book excerpt: Excerpt from Variations and Genetic Relationships of the Garter-Snakes Three steps are necessary to determine the genetic relationships and simplify Cope's elaborate arrangement of the group: (1) The value of the characters must be determined; (2) the geographic prob abilities must be utilized; (3) similarities and intergradations must be sought.

Download or read book Chemical Signals in Vertebrates 4 written by David Duvall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume reviews recent developments in our understanding of che~ ical signaling in vertebrates. After sections dealing with general princi ples and chemical aspects of vertebrate pheromones, it follows a taxonomic approach, progressing from fish to. mammals. The editors asked a diverse, international group of leading investigators, working on a wide array of vertebrate taxa and specific issues, to consider their efforts from compar ative, evolutionary, and ecological viewpoints. The relative number of manuscripts in each part does not necessarily reflect current intensity of research, since the editors invited speakers who together would provide a balanced and comprehensive overview, while avoiding duplication. Still, the part on mammals is the longest. Fourth in a series dating from 1977, this volume illuminates current trends and likely future developments in the field of chemical signaling in vertebrates. Going back even farther, the first chapter, a personal account of the past quarter century by Dr. Mykytowycz recalls the most important milestones, such as symposia, or the founding of societies and journals. He also credits those investigators who stand out by their seminal studies.
Download or read book Geographic Variation in Behavior written by Susan A. Foster and published by Oxford University Press. This book was released on 1999-03-04 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.
