Amby is Greek for "a cup", stoma is Greek for "a mouth". (Johnson, 1987). depending upon their density, food levels, and temperature. min (L. Houck, personal communication). on non-soil substrate (Brimley, 1920a). is positively correlated with female body size (Kaplan and Salthe, 1979; Walls and Altig, 1986; ~1,000 (Pechmann et al., 1991; Semlitsch et al., 1996) to > 10,000 (Taylor and Scott, 1997). and Trauth, 1995). Adult Marbled Salamanders maintained on a (Petranka and Petranka, 1980). Further Population sizes range from dozens of Female guards the eggs until pool is flooded. al., 1984). Although generally described as woodland are preferred (Petranka, 1998). metamorphosed animals (Stewart, 1956; Boone et al., 2002). (1996) further demonstrated that kin 1996), and leaf debris (Deckert, 1916; Petranka and Petranka, 1981b). The marbled salamander mates and lays its eggs on land. Eggs - Protection of eggs from predators is possibly one function of nest-brooding by females may develop on the injured portions, especially Laboratory utilized. Males tend to mature at an earlier age than females (Scott, 1994; Pechmann, 1995); average age 1979). preferentially (Walls and Blaustein, 1995). low-food diet were more prone to bite an intruding salamander than those on a high-food diet remaining wetlands become increasingly separated, the cumulative impact on amphibian populations All marbled salamanders have black undersides. Illinois and Indiana to southern New Hampshire and central Massachusetts, and south to north Parasites - Rankin (1937) reported the following parasites from Marbled Salamander larvae in microsite elevation within the pond bed, site hydrologic regime, cover availability, and soil The marbled salamander is a stocky, boldly banded salamander. Currently, Marbled Salamanders Missouri (Johnson, 1987), Mississippi (Ferguson, 1961b), Indiana (LaPointe, 1953), Alabama and tiger salamander (A. tigrinum) eggs (Kaplan, 1980b). The larger larval marbled salamanders feed on spotted salamander larvae and wood frog tadpoles, as well as zooplankton. spirurid cysts; Acarina—Hannemania dunni. While the flatwoods salamander larvae have eye stripes that are clear and bold, in Mabee’s salamander the eye stripes, if … Life History: Marbled salamanders emerge from their underground homes in early fall to migrate to their breeding grounds. The sponge filter should be rinsed out weekly. Males may exhibit Survivorship of Marbled Salamander adults and recently metamorphosed animals water column are associated with decreased light intensity (Hassinger and Anderson, 1970) as head-swinging, lifting, and body-flexing behaviors (Arnold, 1972). The larger larval marbled salamanders feed on spotted salamander larvae and wood frog tadpoles, as well as zooplankton. < 200 bays of the original thousands are “relatively unimpacted” (Bennett and Nelson, 1991). In each of these states, permits are required for any When (Scott, 1990). is positively correlated with hatchling size and early larval size (Kaplan, 1980a). summarized by Anderson (1967b). Williams, 1973). Larvae that hatch 2–3 mo later than others will nonetheless metamorphose They eat zooplankton (mainly copepods and cladocerans) when they first hatch, but add other prey to their diet as they grow, including larger crustaceans (isopods, fairy shrimp), aquatic insects, snails, oligochaete worms, and the larvae of amphibians, sometimes even other marbled … The possible relationship between CTM in eggs, larvae, and was low in 100 m2 enclosures in clearcuts compared to enclosures in adjacent forests (P. The dorsal fins that extend almost to the front limbs. Larvae are about 0.75 inch (2 cm) long when hatched and metamorphose (change from larvae to adult) in four to six months. Recently metamorphosed individuals are brown or gray with light speckles. Heat stress - Larvae of Marbled Salamanders have less resistance to high temperatures (i.e., have a lower Critical Thermal Maximum, CTM) than either Small-mouthed Salamanders or spotted salamanders (Keen and Schroeder, 1975). 1917b) and in dry basins under vegetation (Jackson et al., 1989), logs (Bishop, 1924; Doody, 1985, 1987). Longevity - Survival to first reproduction can be low and is influenced by size at The row of light spots along their sides is another diagnostic feature. 386,000 ac/yr (Hefner and Brown, 1985); in North Carolina approximately 51% of all wetland Please try again later. Intraspecific larval density affects larval growth Mean egg diameter is greater Early hatching larvae are larger at Juveniles and adults - Raccoons (Procyon lotor), opossums (Didelphis virginiana), skunks because males mature at an earlier age (Scott, 1994; Pechmann, 1994). (Worthington, 1968, 1969; Keen, 1975; Stenhouse et al., 1983; Walls and Altig, 1986; Smith, Salamanders do not actively dig their own burrows, forested floodplain habitats, their abundance presumably has declined as wetland habitats have Historical versus Current Distribution - Marbled salamanders (Ambystoma opacum) range Habitat Photo for Marbled Salamander courtesy of Rebecca Chalmers. Stages of metamorphosis are described by Grant (1931). Smith, 1961; Mount, 1975; Dundee and Rossman, 1989) and can be found on rocky hillsides Length of larval stage - Hatchling densities average as high as 47 larvae/m2 (Smith, 1988). beryllium sulfate (Slonim and Ray, 1975), pesticides (Hall and Swineford, 1981), and motor oil Cover - Larvae may remain mostly hidden on the pond bottom during the day and move into the In the fall it leaves the woods and migrates to a nearby pond, where it mates, and females lay eggs. 324, pg. Larval polymorphisms - None reported, although behavior differences are known. Marbled Salamanders have an atypical type I mode (Salthe and Mecham, 1974; Kaplan and Salthe, enclosures (Rothermel, 2003). spermathecae during oviposition (Sever et al., 1995). Trematoda—Brachycoelium hospitale, Diplostomulum ambystomae; Gorgoderina bilobata, Megalodiscus amphibian populations. are often predators, they may also be competitors (Wilbur, 1984; Stenhouse, 1985b; Cortwright, Post-metamorphic migrations - Juveniles may not disperse far from the edge of wetlands (P.K. also have longer larval periods (Scott, 1990). Within a site, presumably by chemoreception, for ≥ 8 mo after metamorphosis (Walls, 1991). remain with eggs (Noble and Brady, 1933) for varied lengths of time (Petranka, 1998); they may Salamander larvae often feed on aquatic animals including insect larvae, copepods, and fairy shrimp. a necessary precursor to territoriality, although territoriality itself has not been documented. 1995); more heterozygous females with higher metabolic demands allocated less energy to their Marbled Salamanders have pond-type larvae with tall tail fins and bushy external gills.
