It is believed that the growth and energetic physiology of basalmost birds such as Archaeopteryx were inherited in their entirety from non-avialan dinosaurs. This hypothesis predicts that the long bones in these birds formed using rapidly growing, well-vascularized woven tissue typical of non-avialan dinosaurs. Methodology/Principal Findings: We report that Archaeopteryx long bones are composed of nearly avascular parallel- fibered bone. This is among the slowest growing osseous tissues and is common in ectothermic reptiles. These findings dispute the hypothesis that non-avialan dinosaur growth and physiology were inherited in totality by the first birds. Examining these findings in a phylogenetic context required intensive sampling of outgroup dinosaurs and basalmost birds. Our results demonstrate the presence of a scale-dependent maniraptoran histological continuum that Archaeopteryx and other basalmost birds follow.

  • New Insights Into the Biology of Theropod Dinosaurs
    AN ABSTRACT OF THE DISSERTATION OF Devon E. Quick for the degree of Doctor of Philosophy in Zoology presented on December 1, 2008. Title: New Insights into the Biology of Theropod Dinosaurs. Abstract approved: __________________________________________________________ John A. Ruben There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and avascular lungs, although the crocodilian lung is less specialized than the avian lung air-sac system. Essential components of avian lungs include the voluminous, thin-walled abdominal air-sacs which are ventilated by an expansive sternum and specialized ribs. Inhalatory, paradoxical collapse of these air-sacs in birds is prevented by the synsacrum, pubes and femoral-thigh complex. The present work examines the theropod abdomen and reveals that it lacked sufficient space to have housed similarly enlarged abdominal air-sacs as well as the skeleto-muscular modifications requisite to have ventilated them. There is little evidence to indicate that theropod dinosaurs possessed a specialized bird-like, air-sac lung and, by extension, that theropod cardiovascular function was any more sophisticated than that of crocodilians. Conventional wisdom holds that theropod visceral anatomy was similar to that in birds. However, exceptional soft tissue preservation in Scipionyx samnitcus (Theropoda) offers rare evidence of in situ theropod visceral anatomy. Using computed tomography, close comparison of Scipionyx with gastrointestinal morphology in crocodilians, birds and lizards indicates that theropod visceral structure and “geography” was strikingly similar only to that in Alligator.

However, these new approaches need to be supplied by great amounts of data, representative of existing animal forms. We tested whether this is the case by performing a quantitative survey in the most important media for ecological physiologists. We found that ecological physiologists have clear biases toward some taxonomic classes, which represent one third of existing animal phyla. Non–taxonomic characterization of animals (endothermy/ectothermy, aquatic/ terrestrial), however, produced a more balanced picture.

  • Models and Instruments in the Development of Electrophysiology, 1845-1912
    TIMOTHY LENOIR Models and instruments in the development of electrophysiology, 1845-1912 1. INTRODUCTION THE NINETEENTH CENTURY witnessed the transformation of physiology from a discipline characterized by theories based on qualitative, descriptive accounts derived mainly from indirect sources, such as comparative anatomy, into a discipline characterized by theories based on controlled experimental investigations of processes transpiring directly within the organism. Two lines of inquiry helped to bring about this transformation of the field. Some physiologists, particularly the French school of Magendie and Claude Bernard, sought to obtain operative control over the functioning of the organ through vivisection and the application of chemical or physical means. Others, particularly German physiologists, attempted to follow the course of physical and chemical changes during the functioning of isolated organs by means of measurements by appropriate instruments. The expressed objective of this second approach to physiology was the development of quantitative theories of the chemical and physical processes underlying specific organ function. Work in electrophysiology, particularly the research efforts spanning the period between 1845 and 1912, was the most successful example of this approach. Work in electrophysiology dates from the publication of Galvani’s researches on decapitated frogs in 1791 and the ensuing debate with Volta over the nature of "animal electricity." Their investigations were deepened and extended by Humboldt, Ritter, Nobili, Matteucci, and others. The results were qualitative and phenomenological. Not until the work of Emil DuBois-Reymond and Hermann Helmholtz *University of Pennsylvania, Department of History and Sociology of Science, 215 South 34th Street, Philadelphia, PA 19104-6310.

This review examines the historical and current contribution of ecophysiological research conducted from the University of Auckland’s Leigh Laboratory in bridging these paradigms, and generating new insights into animal function and community organisation. The assessment focusses on endocrine control processes, and metabolic and behavioural responses of fish to artificial and natural stressors, and examines tracks of future research needed to underpin understanding of likely effects of predicted environmental change on individuals and populations.

  • Phylogenetic Analyses: Comparing Species to Infer Adaptations and Physiological Mechanisms Enrico L
    P1: OTA/XYZ P2: ABC JWBT335-c100079 JWBT335/Comprehensive Physiology November 1, 2011 18:56 Printer Name: Yet to Come Phylogenetic Analyses: Comparing Species to Infer Adaptations and Physiological Mechanisms Enrico L. Rezende*1 and Jose´ Alexandre F. Diniz-Filho2 ABSTRACT Comparisons among species have been a standard tool in animal physiology to understand how organisms function and adapt to their surrounding environment. During the last two decades, conceptual and methodological advances from different fields, including evolutionary biology and systematics, have revolutionized the way comparative analyses are performed, resulting in the advent of modern phylogenetic statistical methods. This development stems from the realiza- tion that conventional analytical methods assume that observations are statistically independent, which is not the case for comparative data because species often resemble each other due to shared ancestry. By taking evolutionary history explicitly into consideration, phylogenetic statistical methods can account for the confounding effects of shared ancestry in interspecific comparisons, improving the reliability of standard approaches such as regressions or correlations in compara- tive analyses. Importantly, these methods have also enabled researchers to address entirely new evolutionary questions, such as the historical sequence of events that resulted in current patterns of form and function, which can only be studied with a phylogenetic perspective. Here, we pro- vide an overview of phylogenetic approaches and their importance for studying the evolution of physiological processes and mechanisms. We discuss the conceptual framework underlying these methods, and explain when and how phylogenetic information should be employed. We then outline the difficulties and limitations inherent to comparative approaches and discuss po- tential problems researchers may encounter when designing a comparative study.
