Spatial Ecology of the Spotted Salamander <em>Ambystoma maculatum</em> During the Nonbreeding Season.
<p>Spotted Salamanders, <em>Ambystoma maculatum</em>, are a widely distributed pond-breeding amphibian that spends an estimated 95% of its life in woodlands surrounding breeding ponds. Their terrestrial ecology remains poorly understood. Few studies have tracked the movement patterns of Spotted …

Conservation genetics of a spotted salamander (Ambystoma maculatum (Shaw 1802)) local population in southeast Tennessee
Currently there is a worldwide amphibian decline with numerous causes. Because of this, it is important to understand how genetic variation in local amphibian populations is affected by disturbance. The goal of this study was to assess the genetic impacts of past chemical and ammunition storage and …

Level of UV-B Radiation Influences the Effects of Glyphosate-Based Herbicide on Fitness of the Spotted Salamander
… and morphological plasticity of larvae of the spotted salamander (Ambystoma maculatum) under conditions that reflect open and closed canopy light regimes. Larval salamander responses to glyphosate-based herbicide varied depending on UV-B conditions. In general, it appears that an open canopy …

Annual variation in timing, orientation and effects of weather on Jefferson salamander (Ambystoma jeffersonianum) and spotted salamander (Ambystoma maculatum) movements in central Kentucky
… County, Kentucky. The pond was checked daily for salamander movements from 17 January 2010 to 26 September 2010 and from 26 January 2011 to 3 August 2011, which corresponded to the activity season. Weather variables examined in relation to amphibian movements included barometric pressure, …

Survivorship of ploidy-variable unisexual <i>ambystoma</i> aalamanders across developmental stages
… <em>Ambystoma</em> species (e.g., Jefferson's Salamander <em>A. jeffersonianum</em>, and the Blue-Spotted Salamander <em>A. laterale</em>). Kleptogenesis can result in ploidy-variable embryos within an egg mass because the female may or may not incorporate the male ambystomatid genome. Little …

Abiotic Factors Underlying Stress Hormone Level Variation Among Larval Amphibians
… the larvae of four amphibian species: Jefferson salamander (Ambystoma jeffersonianum), spotted salamander (A. maculatum), wood frog (Rana sylvatica), and grey treefrog (Hyla versicolor). Chapter II examined corticosterone level differences throughout development in A. jeffersonianum and R. …

The Influence of Tail Autotomy on Avoidance of Chemical Alarm Cues in Northern Zigzag Salamanders, Plethodon dorsalis
… that pose an increased predation risk salamanders may use predator avoidance. Salamanders detect chemical alarm cues via the vomeronasal organ and their avoidance of the chemical cues is based upon the apparent associated risk. The objective of this study was to better understand …

Population Size and Movements of Spotted Salamanders at South Holston Dam, Sullivan County, Tennessee.
… Appalachians, there are growing concerns about Spotted Salamanders (<em>Ambystoma maculatum</em>) due to habitat destruction and the uncertain future of their forested riparian habitat. In this study, I establish baseline data of a population of Spotted Salamanders so future monitoring of this …
