Laskowski Principles of Life—The New Edition Because success as a biologist means more than just succeeding in the first biology course. For instructors concerned that the practical skills of biology are lost when the student moves on to the next course or takes their first step into the “real world,” Principles of Life, Third Edition lays the foundation for later courses and for students’ careers. Expanding on its pioneering concept-driven approach, experimental data-driven exercises, and active learning focus, the new edition introduces features designed to involve students in mastering concepts and becoming skillful at solving biological problems. Research shows that when students engage with a course, it leads to better outcomes. Principles of Life, Third Edition is a holistic solution that has been designed from the ground up to actively engage students in mastering concepts and becoming skilled at solving biological problems. Within LaunchPad, our digital teaching and learning solution, we provide thoughtfully curated assignments and activities to support pre-lecture preparation, classroom activities, and post-lecture assessment. 2018 With its focus on key competencies foundational to biology education and careers, self-guided adaptive learning, and unparalleled instructor resources for active classrooms, Principles of Life is the resource students need to succeed. A FOCUS ON (c) SKILLS AND CORE COMPETENCIES New to this edition, the AAAS Vision and Change report’s six “core competencies” related to quantitative reasoning, simulation, and communication, are integrated both implicitly throughout the text and explicitly in a new Cokey feature, Think Like a Scientist.

  • REDISCOVERING BIOLOGY Evolution and Molecular to Global Phylogenetics Perspectives
    REDISCOVERING BIOLOGY Evolution and Molecular to Global Phylogenetics Perspectives “Systems of classification are not hat racks, objectively presented to us by nature. They are dynamic theories developed by us to express particular views about the history of organisms. Evolution has provided a set of unique species ordered by differing degrees of genealogical relationship. Taxonomy, the search for this natural order, is the fundamental science of history.” STEPHEN J GOULD 1 Perhaps the most striking feature of life is its enormous diversity. There are more than one million described species of animals and plants, with many millions still left undescribed. (See the Biodiversity unit.) Aside from its sheer numerical diversity, organisms differ widely and along numerous dimensions — including morphological appearance, feeding habits, mating behaviors, and physiologies. In recent decades, scientists have also added molecular genetic differences to this list. Some groups of organisms are clearly more similar to some groups than to others. For instance, mallard ducks are more similar to black ducks than either is to herons. At the same time, some groups are very similar along one dimension, yet strikingly different in other respects. Based solely on flying ability, one would group bats and birds together; however, in most other respects, bats and birds are very dissimilar. How do biologists organize and classify biodiversity? In recent decades, methodological and technological advances have radically altered how biologists classify organisms

  • Biogeography, Phylogeny, and Morphological Evolution of Central Texas Cave and Spring Salamanders
    Biogeography, phylogeny, and morphological evolution of central Texas cave and spring salamanders Bendik et al. Bendik et al. BMC Evolutionary Biology 2013, 13:201 http://www.biomedcentral.com/1471-2148/13/201 Bendik et al. BMC Evolutionary Biology 2013, 13:201 http://www.biomedcentral.com/1471-2148/13/201 RESEARCH ARTICLE Open Access Biogeography, phylogeny, and morphological evolution of central Texas cave and spring salamanders Nathan F Bendik1,2*, Jesse M Meik3, Andrew G Gluesenkamp4, Corey E Roelke1 and Paul T Chippindale1 Abstract Background: Subterranean faunal radiations can result in complex patterns of morphological divergence involving both convergent or parallel phenotypic evolution and cryptic species diversity. Salamanders of the genus Eurycea in central Texas provide a particularly challenging example with respect to phylogeny reconstruction, biogeography and taxonomy. These predominantly aquatic species inhabit karst limestone aquifers and spring outflows, and exhibit a wide range of morphological and genetic variation. We extensively sampled spring and cave populations of six Eurycea species within this group (eastern Blepsimolge clade), to reconstruct their phylogenetic and biogeographic history using mtDNA and examine patterns and origins of cave- and surface-associated morphological variation. Results: Genetic divergence is generally low, and many populations share ancestral haplotypes and/or show evidence of introgression. This pattern likely indicates a recent radiation coupled with a complex history of intermittent connections within the aquatic karst system. Cave populations that exhibit the most extreme troglobitic morphologies show no or very low divergence from surface populations and are geographically interspersed among them, suggesting multiple instances of rapid, parallel phenotypic evolution. Morphological variation is diffuse among cave populations; this is in contrast to surface populations, which form a tight cluster in morphospace.

Their Point of View is not about promoting transparency in the process of constructing the English Names list, assuring that its taxonomy is adequately reviewed, or promoting nomenclatural stability in any global sense. Rather, their Point of View focuses in large part on a single publication, The Amphibian Tree of Life, which is formally unrelated to the Standard English Names List, and promotes an approach to nomenclature mistakenly asserted by them to be compatible with both the International Code of Zoological Nomenclature and one of its competitors, the PhyloCode.

Gutell Phylogenetic Systematics, Historical Biogeography, and the Evolution of Vocalizations in Nearctic Toads (Bufo) by Gregory Blair Pauly, B.S. Dissertation Presented to the Faculty of the Graduate School of The University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy The University of Texas at Austin August 2008 Dedication To my parents, Matthew and Georgia, for many years of support and encouragement. Acknowledgements Many people have contributed to my dissertation research and to the earlier path that brought me to this point. First, I thank my parents, Matthew and Georgia, for their lifelong support and constant encouragement of my interests in science, the outdoors, and all things herpetological. I also thank my sister, Sara, and extended family for their encouragement. My family's appreciation of education, hard work, and the natural world has strongly influenced my career choices and contributed to my love of biology. I am truly grateful to the research opportunities provided to me by Brad Shaffer and Arthur Shapiro during my undergraduate career. Their mentorship was critical to my development as an academic biologist. In particular, in my first month as an undergraduate researcher in Brad Shaffer's lab, I went from a stressed out senior with no idea of what I would do after graduating to knowing what I would do for the rest of my life.
