Growth and Metamorphosis of the Ringed Salamander
Observations of the ringed salamander, Ambystoma annulatum, from Stone County, Missouri, were made during 1983 and 1984. Deposition of eggs on land and development of eggs out of the water were observed. Larvae hatched at a mean total length of 11.4 mm and metamorphosed at a mean total length of …

Predation of Ringed Salamander Larvae, Ambystoma Annulatum
Predation on larval Ambystoma annulatum was studied in 1991-1993. The following predators, which are normally present in the breeding ponds of A. annulatum during larval development, were studied : dragonfly nymphs (Anax and Tramea), waterbugs (Belostoma), backswimmers (Notonecta), and newts …

Feeding kinematics of the grotto salamander, Eurycea spelaea
All larval salamanders that have been studied capture prey using inertial suction feeding, and the kinematics were at one time thought to be highly stereotypical. Many salamanders have been studied, but the life history of Eurycea spelaea, the grotto salamander, is unique among the troglobitic …

The Impact of Logging on Aquatic Salamander Communities.
<p>For this study, the abundance of the salamander fauna in two streams was compared to determine the impact of logging activities. After five months of study, the area around one stream was logged by the National Forest Service. Following logging, the abundance of salamanders in the stream was …

RESISTANCE AND RESILIENCE OF STREAM SALAMANDER POPULATIONS TO DISTURBANCE
… of small, first-order streams. Stream salamanders (Family Plethodontidae) represent the dominant vertebrate group and play important ecological roles in first-order streams, although they have often been neglected in previous studies on the effects of disturbance on system ecosystems. …

Predator Recognition and Avoidance in the San Marcos Salamander
… of effectiveness and efficiency. The San Marcos salamander (Eurycea nana) is a fully aquatic salamander endemic to the headwaters of the San Marcos River. Eurycea nana is subject to predation by a diverse community of native and nonnative fish predators. Despite the importance of predation …

Developing a predictive geospatial habitat model for a rare species of salamander in Tennessee: a case study for the green salamander (Aneides aeneus)
Green Salamanders (Aneides aeneus; Cope and Packard 1881) are a secretive and cryptic species of salamander that can be relatively difficult to detect, due to their occupation of arboreal habitats. The incorporation of geospatial tools is critical in developing models that can be used to predict …

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, …

Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… studies in a little studied species, the marbled salamander (Ambystoma opacum). I studied female mating behavior, sexual selection, and the consequences of polyandry for individual females and salamander populations. I also compared the performance of several statistical approaches for analyzing …

A Behavioral Syndrome in the Southern Red-Backed Salamander (Plethodon Serratus)
… I compared behavior of adult southern red-backed salamanders (Plethodon serratus) in two contexts: (1) exploring unfamiliar territory, and (2) learning to adopt a foraging task. A behavioral syndrome was present for females; individuals that excelled in the foraging task also had a tendency to …
