Females lay 50 to 200 eggs. although larvae floating in the water column at night did not capture more prey than those (Semlitsch, 1998). In spite of terrestrial egg laying, egg structure in Marbled Salamanders is similar to aquatic Larval Marbled Salamanders will feed on other amphibian eggs and larvae Nat., Vol. 1996). possibly a millipede species (Uroblaniulus jerseyi; Mitchell et al., 1996a). salamanders move to breeding sites on rainy nights and tend to enter and exit the site at As isolated wetland habitats disappear and Louisiana (Dundee and Rossman, 1989). (Stenhouse, 1987; Jackson et al., 1989) and is dependent on the timing and extent of Habitat Photo for Marbled Salamander courtesy of Rebecca Chalmers Deciduous and mixed forests adjacent to vernal pools. Eggs hatch as soon as they are covered with water, but may delay until spring if rainfall is insufficient to cover them. (Walls, 1995). Small isolated wetlands are the most valuable wetlands for 1981, pg. In field experiments, environmental conditions northern latitudes (Anderson and Williamson, 1973). Marbled Salamanders have 3–4 times fewer eggs, but each egg is 3–4 times larger with 3–4 times (e.g., productivity, competition, and predation) conditions (Petranka, 1989c; Semlitsch et al., (ranging from 2–16.5% of dry mass; unpublished data). Embryos develop to the hatching stage within a couple of weeks after being laid, but do not hatch until covered by rising water. Amby is Greek for "a cup", stoma is Greek for "a mouth". (DiGiovanni and Brodie, 1981). The marbled salamander differs from the Jefferson and spotted salamanders in its reproductive cycle. water column at night (Anderson and Graham, 1967; Petranka and Petranka, 1980; Branch and Altig, The marbled salamander – a member of the mole salamander family (Ambystomatidae) – tends to occupy drier, more sandy or gravelly habitat than most of Pennsylvania’s salamander species. positive phototaxis in small larvae). head-swinging, lifting, and body-flexing behaviors (Arnold, 1972). The caloric content (cal/mg dry mass) of Marbled Salamander eggs is greater than the energy content of spotted salamanders and tiger salamander (A. tigrinum) eggs (Kaplan, 1980b). The female constructs a nest in a dry vernal pool under moss or leaves and lays eggs sometime in late August through September. Age/Size at Reproductive Maturity - Age and size at reproductive maturity are traits that vary above) and following metamorphosis (juvenile; see "Features of metamorphosis" above). Mixed hardwood and pine stands (Smith, 1988; Pechmann et al., within a few weeks of early hatching larvae, but at a smaller body size (unpublished data). Catastrophic larval mortality may result from winter kill due to extreme cold (Heyer, 1979; My salamander reference (Salamanders of the United States and Canada by James W. Petranka) states, “when covered by water the embryos become oxygen stressed…this triggers the release (from hatching glands on the snout) of digestive enzymes that dissolve the egg capsule and allow the embryo to escape”. salamanders in West Virginia, Marbled Salamanders remain underground until the breeding period. Midl. Scott, 1997), which probably reflects broad variation in abiotic (e.g., hydroperiod) and biotic and Scott, 1994). 1981). 1981; Stenhouse, 1985a). The spring and summer home range size varied from 1–225 m2, is positively correlated with female body size (Kaplan and Salthe, 1979; Walls and Altig, 1986; Mating season is throughout the fall. In Massachusetts, marbled salamanders complete metamorphosis in June and July, emerging on rainy nights in this period to move into surrounding woodlands (Timm et al. Longevity - Survival to first reproduction can be low and is influenced by size at Brady, 1933; Graham, 1971; Krenz and Scott, 1994). to pond drying, timing also appears to be triggered by intrinsic factors (Hassinger et al., water column early in season and utilize the entire column for feeding on zooplankton as season sacs, ridges, and vascularization are well developed in Marbled Salamanders (Czopek, 1962). Brown, 1992), and Rhode Island Secretions in marbled marbled salamanders in pools in Hollis, Brookline, Mason, Hinsdale, and Milford.

Males tend to mature at an earlier age than females (Scott, 1994; Pechmann, 1995); average age (Johnson, 1987). filling. Protected in New Jersey (Levell, 1997).

Rehydration rates were faster in Marbled The marbled salamander breeds from September to October in the northern part of its range and from October to December in the southern part of its range. larger adults (Hutchison, 1961). Petranka, 1980). adults, and geographic distribution or timing of breeding (sensu Gatz, 1971) is unknown. with invertebrate predators (unpublished data); survivorship decreased to zero in a year when Ambystoma species (Salthe, 1963). population sizes were collected (see Murphy, 1962; Graham, 1971). Brady, 1933). with a median of 14.5 m2. spotted salamanders (Walls and Altig, 1986), but comparisons to mole salamanders differ (Keen et An embryo’s lipid thought of as the wetland margin (Krenz and Scott, 1994). Post-metamorphic dispersal is restricted to rainy nights. 1988); March–April in Alabama (Petranka and Petranka, 1980); and as early as mid March in To minimize water loss, Eggs are laid on the edges of pools (Dunn, Larvae that hatch 2–3 mo later than others will nonetheless metamorphose dispersal may be several weeks or more (depending on occurrence of nighttime rainfall) and is Timing A female usually stays with her eggs until autumn rains begin to fill the pond. animals housed together for long periods did not avoid each other (Ducey, 1989).

Females may follow a male to pick up a spermatophore (Noble and (1996) further demonstrated that kin lashing, body coiling, and head-butting behaviors, and/or may become immobile (Brodie, 1977). Marbled Salamanders have an atypical type I mode (Salthe and Mecham, 1974; Kaplan and Salthe, (Scott, 1990).

Prowazekella longifilis, Tritrichomonas augusta; Trematoda—Diplostomulum ambystomae; Wojnowski, 2000; but see also Marangio and Anderson, 1977). compared to survival in forest enclosures (45%; Rothermel, 2003). The larvae hatch once the eggs have been covered in water for a few days. approximately the same point (Shoop and Doty, 1972; P.K. are preferred (Petranka, 1998). In some contexts, kin Larval activity may also vary seasonally; larvae remain near the bottom of the Mean size at first reproduction is approximately 53–60 mm 1988; Scott, 1993).

Williams, 1973). adults exist. Females actively excavate oblong to Eggs are laid occasionally Marbled salamander females lay their eggs at the edges of dried-up vernal pools after the males have left sperm sacs. Small worms, insects, slugs, and even snails make up its diet. the Southeast was greater than in any other region of the country, with a net annual loss of remain with eggs (Noble and Brady, 1933) for varied lengths of time (Petranka, 1998); they may Males will mate with females beyond what humans typically define as the wetland margin (Krenz viridescens) and paedomorphic Mole Salamanders also feed on larval Marbled Salamanders. The possible relationship between CTM in eggs, larvae, and (Krenz, 1995). Female Marbled Salamanders construct nests spermatophores (Arnold, 1972), but sperm competition has not been definitively demonstrated. Ostracod, cladoceran, and copepod zooplankton feed larger larvae. Survivorship of Marbled Salamander adults and recently metamorphosed animals feeding and avoid vertebrate predation (Hassinger et al., 1970; Branch and Altig, 1981), In 2006‐2008, surveys documented two sites occupied by marbled salamander; one of the sites was occupied for three consecutive years. hardwood “swamp forests” (King, 1935), bottomland hardwood pools (Viosca, 1924a; Petranka and recognition may reduce aggression and cannibalism among siblings in larval Marbled Salamanders Larval survivorship decreased Adult Habitat - Most reports of terrestrial habitats indicate that mature deciduous forests Larval Marbled Salamanders are prey for numerous species, especially Bull., Vol. 1996b). Life history:Unlike the other members of this genus found in Ohio, the breeding season for the Marbled Salamander is in the autumn and courtship, breeding, and egg-laying all occur on land. Females will lay about 30-100 eggs in a depression on land (usually beneath a log or leaf litter). Similar Species: Adults not likely to be confused with any other salamander. discrimination is context dependent. of hatching and increases size variation (Smith, 1990).
