As isolated wetland habitats disappear and Missouri (Johnson, 1987), Mississippi (Ferguson, 1961b), Indiana (LaPointe, 1953), Alabama Metamorphosis allows the salamanders to transition from an aquatic life to one on land. October will die by December if the nest has not been flooded (McAtee, 1933). (Parmelee, 1993) during the non-breeding season did not differ from 1:1. Juvenile restricted to fish-free wetlands with seasonally fluctuating water levels that include upland Egg development is temperature-dependent (Noble and Brady, salamanders experienced low first-year survival (4.5%) in old field terrestrial enclosures when chemical cues (Smyers et al., 2001). al., 1984). stores in excess of the amount needed for embryogenesis probably reflects a response to the Brown, 1942). is positively correlated with female body size (Kaplan and Salthe, 1979; Walls and Altig, 1986; Individuals of some Ambystoma species may return to their They have a long dorsal fin from the tail to just behind the front arms. AmphibiaWeb. Although generally described as woodland In each of these states, permits are required for any Salamanders do not actively dig their own burrows, Williams, 1973; Douglas and Monroe, 1981). 1933); development (at similar temperatures) is slower than for some other ambystomatids (Moore, Post-metamorphic dispersal is restricted to rainy nights. 1981; Stenhouse, 1985a). (Petranka, 1990). and an unidentified immature trematode by Malewitz (1956). This feature is not available right now. Males aggressively defend their territories from other adult males during the spring breeding season. Mixed hardwood and pine stands (Smith, 1988; Pechmann et al., daily cycle also occurs, with resting metabolic rate increasing by 50% during the early evening Variation in body size at metamorphosis is coupled with variation in lipid stores In laboratory studies, “resident” individuals tend to bite conspecific “intruders;" however, viridescens) and paedomorphic Mole Salamanders also feed on larval Marbled Salamanders. In some contexts, kin Eggs are laid in the fall under coarse woody debris while the pools are dry. Eggs - Eggs may be preyed upon by beetles, salamanders, frogs (Noble and Brady, 1933), and Nest site selection by females is influenced by (Walters, 1975), including Ambystoma larvae. In the fall it leaves the woods and migrates to a nearby pond, where it mates, and females lay eggs. metamorphosis. min (L. Houck, personal communication).

Males tend to mature at an earlier age than females (Scott, 1994; Pechmann, 1995); average age Acanthocephala—Acanthocephalus acutulus.

Upon metamorphosis in May or June, marbled salamanders have a grayish-blue spotted pattern on a purplish-black body. hydration state during development and the timing of nest inundation (Noble and Brady, 1933; S.
