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 …

Food Habits of Larval Ringed Salamanders, Ambystoma Annulatum
Larval Ambystoma annulatum were collected from two ponds in Stone County, Missouri during 1989-1990 for a food habits study. Larvae fed on a variety of organisms. The major food items consisted of microcrustaceans, nematodes, and dipteran larvae. The diet changed both with development and season. …

Learning of Dietary Cues By Embryos and Larvae of Ringed Salamanders (Ambystoma Annulatum)
… the hypothesis that larval ringed salamanders (Ambystoma annulatum) exposed to a novel food scent as embryos will exhibit a preference for the scent post-hatching. Embryos were exposed to brine shrimp or a water control. After hatching, behavior of larvae was quantified following exposure to …

A Skeletochronological Study to Determine the Age of the Ringed Salamander (Ambystoma Annulatum)
… 202 sexually mature ringed salamanders (Ambystoma Annulatum) were caught in a semi-permanent pond by using pit-fall traps and drift fence. The sex ratio strongly deviated from a 1:1 ration and approached 3:1 in favor of males. The average snout-vent lengths were significantly higher …

Genetic diversity and distribution of the ringed salamander (Ambystoma annulatum) across multiple spatial scales
… ... Across its distribution, I found that A. annulatum exists as two genetic clusters that correspond to watershed boundaries. Within each cluster, I found evidence for decreased gene flow in recent generations, possibly due to the extensive timber harvest and land conversion of the CIH post …

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 …

Response Of Salamanders To Chemical Stimuli From Predators In Natural Habitats
… (2) responses of larval ringed salamanders, Ambystoma annulatum, to chemical stimuli from predatory newts, Notophthalmus viridescens, and (3) responses of terrestrial southern red-backed salamanders, Plethodon serratus, to chemical stimuli from predatory ringneck snakes, Diadophis punctatus. …
