Evolutionary physiology of New Zealand stick insects: A thermal biology approach
… capacity, are obligated to modify their physiology to cope with short- or long-term temperature changes through phenotypic plasticity or adaptation. Although many single-species studies document how ectotherms tune their phenotypes in response to temperature, our understanding of how …

Quantitative genetics and metabolomics of aerobic metabolism
… (MMR) are important for understanding exercise physiology and the evolution of aerobic performance, but they still are not well understood. To this end, I studied three aspects of MMR. First, I estimated the genetic variances and covariances of MMR and basal metabolic rate (BMR). Second, I …

Comparative Morphometrics of the Sacral Vertebra in <em>Aneides</em> (Caudata: Plethodontidae).
<p>The genus <em>Aneides</em> (Caudata: Plethodontidae) is an arboreal salamander with a prehensile tail and a distribution that spans North America. It is hypothesized that adaptations for arboreality will be visible in the osteology of the sacral vertebra either by qualitative analysis or linear …

The influence of spatiotemporal variation in ambient temperature on the ecology and physiology of birds
… temperature has profound effects on the ecology, physiology and distribution of organisms. Ambient temperature regimes vary across spatial and temporal scales and understanding how organisms cope with this variation is a primary goal of ecological and evolutionary physiology. An emerging framework …

Effects of Supplemental Hydration on Physiology and Behavior of Northern Pacific Rattlesnakes (Crotalus oreganus oreganus)
… state of these animals influences their physiology and behavior. We tested for an effect of hydration on several physiological and behavioral parameters in Northern Pacific rattlesnakes (<em>Crotalus oreganus oreganus</em>) by experimentally manipulating hydration levels in the field. Two …

Araucaria in the Urban Landscape: A Novel Leaning Pattern and Evidence of Cultivated Hybridization
<p>Our understanding of the natural world is constantly evolving and strengthening as more observations are made and experiments are performed. For example, we understand that tree stems grow toward the light (positive phototropism; Darwin 1880, Loehle 1986, Christie et al. 2013) and against …

Phylogeny of <em>Panthera</em>, Including <em>P. atrox</em>, Based on Cranialmandibular Characters
<p>Over the past 20 years both morphological and molecular phylogenies have been proposed for extant and extinct members of the family Felidae. However, there remain several discrepancies, particularly within the genus <em>Panthera</em> and the position of <em>Panthera atrox</em>. Consequently, …

Characterization of Andrenocortical Tissue Morphology, Histology, and Steroid Synthesis Among Finetooth (<i>Carcharhinus isodon</i>), Blacktip (<i>Carcharhinus limbatus</i>), Atlantic Sharpnose (<i>Rhizoprionodon terraenovae</i>), and Bonnethead (<i>Sphyrna tiburo</i>) Sharks
<p>Adrenocortical (interrenal) tissue is composed of steroidogenic cells that produce corticosteroids involved in the stress response and hydromineral balance. Previous research characterizing the elasmobranch interrenal suggests that the number of interrenal bodies that produce the single primary …

The Time-Course of the Effects of Growth Hormone During Zebrafish (<i>DANIO RERIO</i>) Auditory Hair Cell Regeneration
<p>Growth hormone (GH) was upregulated in the zebrafish inner ear following sound exposure in a previous study. To identify the specific role of GH in hair cell regeneration and the possible cellular mechanisms of this regeneration, groups of zebrafish were divided into baseline (no sound exposure, …

RELATING METABOLIC PHENOTYPES TO MOVEMENT BEHAVIOR IN BROOK TROUT
<p>Brook trout movement-related life history strategies vary considerably and range from individuals that stay within the same 100 meters their entire life to individuals that are potamodromous or anadromous. Potential drivers of movement life histories have been the subject of much research in …

Physiological variation of Garry oak (Quercus garryana) seedlings to drought stress
The purpose of this study was to determine physiological differences in drought response among Garry oak (<em>Quercus garryana</em> Douglas ex Hook. [Fagaceae]) seedlings that grow in distinct populations in Washington state, in order to aid in restoration efforts by informing growers of the …

Effect of Oxygen-Limiting Tidal Conditions on Muscle Metabolism and Structure in the Giant Acorn Barnacle, Balanus nubilus
<p>Crustacean muscle fibers are some of the largest cells in the animal kingdom, with fiber diameters in the giant acorn barnacle (<em>Balanus nubilus</em>) exceeding 3 mm. Sessile animals with extreme muscle sizes and that live in the hypoxia-inducing intertidal zone – like <em>B. nubilus</em> – …
