Comparative Morphometrics of the Sacral Vertebra in <em>Aneides</em> (Caudata: Plethodontidae).
… (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 and morphometric analysis …

Effects of Supplemental Hydration on Physiology and Behavior of Northern Pacific Rattlesnakes (Crotalus oreganus oreganus)
… such as protein production, innate immunity, and behavioral processes such as daily activity and thermoregulation. Few studies have directly assessed the effect of hydration on these animals in nature. While it seems intuitive that drought is stressful to animals, studies examining drought are …

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
… 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 corticosteroid, 1a-hydroxycorticosterone (1a-OHB), varies among species. However, …

The Time-Course of the Effects of Growth Hormone During Zebrafish (<i>DANIO RERIO</i>) Auditory Hair Cell Regeneration
… 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, no injection), buffer-injected and GH-injected groups. Buffer- and GH-injected fish were exposed to a 150 Hz tone at a …

RELATING METABOLIC PHENOTYPES TO MOVEMENT BEHAVIOR IN BROOK TROUT
… 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 fish, with genetic …

Physiological variation of Garry oak (Quercus garryana) seedlings to drought stress
… as well as one population from Whidbey Island, were collected and grown in containers under controlled conditions. The plants were assessed with and without moderate and severe drought stress induced by withholding water. The most extreme differences in photosynthetic characteristics for …

Effect of Oxygen-Limiting Tidal Conditions on Muscle Metabolism and Structure in the Giant Acorn Barnacle, Balanus nubilus
… 3 mm. Sessile animals with extreme muscle sizes and that live in the hypoxia-inducing intertidal zone – like <em>B. nubilus</em> – represent ideal models for probing the effects of oxygen limitation on muscle cells. We investigated changes in metabolism and structure of <em>B. nubilus</em> muscle …
