the Southeast was greater than in any other region of the country, with a net annual loss of this predation due to increased use of refugia by Mole Salamanders (Walls, 1995). The female usually curls her body around the eggs to keep them moist and waits for rain to fill the depression. and Trauth, 1995). Marbled Salamander adults in the same populations: Protozoa—Cryptobia borreli, Cytamoeba subsequent winter rains (Noble and Brady, 1933). unpredictability in the timing of hatching (i.e., the duration of the egg stage). activity involving Marbled Salamanders. within a few weeks of early hatching larvae, but at a smaller body size (unpublished data). For example, from the 1950s–'70s the loss of wetlands in Truett, 1964), Louisiana (Dundee and Rossman, 1989), southeastern Oklahoma (Trowbridge, 1937), chain pickerel (Esox niger) colonized the wetland. When the marbled salamanders are about six months old, the salamanders can be moved to an adult feeding regimen. generally disperse from the breeding site in late spring. Adults are unpalatable to common ribbon snakes Embryos develop to the hatching stage within a couple of weeks after being laid, but do not hatch until covered by rising water. juvenile Mole Salamanders did not show any overt aggression, perhaps indicating that such Brady, 1933; Graham, 1971; Krenz and Scott, 1994). The spring and summer home range size varied from 1–225 m2, (Stenhouse, 1987; Jackson et al., 1989) and is dependent on the timing and extent of Female A. opacum with eggs. 3, 346 pgs., Indiana Academy of Science, Indianapolis, Petranka, J.W., Petranka, J.G., 1981, On the evolution of nest site selection in the marbled salamander, Ambystoma opacum, Copeia, Vol. leave before eggs are inundated (McAtee, 1933; Jackson et al., 1989; Petranka, 1990). but enlarge existing openings (Semlitsch, 1983a). increased prey density promotes larger size at metamorphosis (Stewart, 1956). 1988). In each of these states, permits are required for any Small-mouthed Salamanders (Ambystoma texanum), they suggested that territoriality might be expected in Marbled Salamanders. In spite of terrestrial egg laying, egg structure in Marbled Salamanders is similar to aquatic The possible relationship between CTM in eggs, larvae, and Larval survivorship decreased jeffersonianum; Cortwright, 1988), tiger salamanders (Stine et al., 1954), and mole salamanders Photo by Bob Thomas. summarized by Anderson (1967b). and a suite of larval traits (Stenhouse et al., 1983; Stenhouse, 1985b; Smith, 1988, 1990; spotted salamanders (Walls and Altig, 1986), but comparisons to mole salamanders differ (Keen et Laboratory It was very moist under the log but the standing water was still a few inches away from the eggs. (Semlitsch, 1998). (unpublished data). dry mass) of Marbled Salamander eggs is greater than the energy content of spotted salamanders discrimination is context dependent. 474-495, King, W., 1935, Ecological observation on Ambystoma opacum, Ohio J. The female lays 50-200 eggs, one at a time, in a depression under a log or in a clump of vegetation that will fill with water when it rains. Consequently, although larval Marbled Salamanders summer inactivity, corresponding to periods of little or no rainfall. Adults take terrestrial invertebrates, such as worms, insects, centipedes, and mollusks (snails, slugs). Society, Handbook of Larval Amphibians of the United States and Canada. metamorphosis, have higher survival, and metamorphose earlier than late-hatching larvae (Boone opacum is Latin hydration state during development and the timing of nest inundation (Noble and Brady, 1933; S. There was a tendency for home range size to increase as individuals Brown, 1942). Small, lean animals may suffer the highest Small-mouthed Salamanders (Walters, 1975; Doody, 1996), Jefferson Salamanders (A. have a lower Critical Thermal Maximum, CTM) than either Small-mouthed Salamanders or spotted et al., 2002). Marbled salamanders have been used in toxicological tests of hydrazine compounds (Slonim, 1986), lashing, body coiling, and head-butting behaviors, and/or may become immobile (Brodie, 1977).
