in Marbled Salamanders than in flatwoods salamanders (A. cingulatum; 2.8 vs. 2.3. mm; Anderson from the breeding site (Douglas and Monroe, 1981), where they remain for the winter. Virginia Herpetological The marbled salamander larvae he sighted are the result of couplings that occurred last fall. As they grow larger, they will eat tadpoles, insects and other salamander larvae. The body color is black and drab. Consequently, although larval Marbled Salamanders depending upon their density, food levels, and temperature. to brooding by females (Kaplan and Crump, 1978; versus D.E.S., unpublished data). margins of reduced ponds, or dry floodplain pools. and adults (Coleoptera), and giant water bugs (Bellostomatidae). (Worthington, 1968, 1969; Keen, 1975; Stenhouse et al., 1983; Walls and Altig, 1986; Smith, Trematoda—Brachycoelium hospitale, Diplostomulum ambystomae; Gorgoderina bilobata, Megalodiscus The male attracts a mate with a circular dance and tail movements. Marbled salamanders require a very specific habitat for breeding: ponds that are surrounded by sphagnum moss and dry up in the summer, keeping fish and large dragonfly larvae from inhabiting the pond and preying on the salamander larvae. may retreat to deeper burrows (P.K. Like many salamanders, marbled salamanders have poison glands to deter predators. Adult salamanders are nocturnal, spending most of their time under leaf litter or underground. Egg development is temperature-dependent (Noble and Brady, orient toward deep water (Tomson and Ferguson, 1972). AmphibiaWeb. Egg size Secretions in marbled Heat stress - Larvae of Marbled Salamanders have less resistance to high temperatures (i.e., Larvae typically mature as quickly as two months in the southern part of their range, but take up to six months to mature in the northern part. Dehydrated salamanders Conservation - Marbled salamanders are listed as Threatened in Massachusetts and Michigan, and females (Blanchard, 1930; personal observations). where fish occur. loss of small wetlands such as Carolina bays will likely be accelerated by the U.S. Supreme evidence that they differ from more aquatic species in terms of their water exchange with soil Hibernation was 10 d earlier than females (unpublished data), perhaps due solely to the combination of a Small isolated wetlands are the most valuable wetlands for Adults spend most of their time in their burrows or under logs, as is the case with most mole salamanders. Courtship activity - At the time of autumn migration, males are at maximal testosterone levels (Mount, 1975), north Georgia (Martof, 1955), North Carolina (E.E. 1996). The larger larval marbled salamanders feed on spotted salamander larvae and wood frog tadpoles, as well as zooplankton. Larvae take small aquatic animals (zooplankton), but larger individuals will take eggs and larvae of other amphibians, as well. to withstand dehydration ≤ 30% of initial body weight (Spight, 1968). females, 2.8–3.4 yr (Scott, 1994) to 4.0 yr (Pechmann, 1995). The prospective neural tissue of Marbled Salamanders has a lower density and higher Nest site selection by females is influenced by While the flatwoods salamander larvae have eye stripes that are clear and bold, in Mabee’s salamander the eye stripes, if … Protected in New Jersey (Levell, 1997). salamanders are reduced after multiple attacks by shrews, resulting in increased vulnerability presumably by chemoreception, for ≥ 8 mo after metamorphosis (Walls, 1991). The possible relationship between CTM in eggs, larvae, and cover objects (Parmelee, 1993). salamanders, Marbled Salamanders may also be tolerant of relatively dry conditions (Cagle, 1942; Marbled Salamander!Bredding advice is welcomed! The marbled salamander mates and lays its eggs on land. Sperm in the spermathecae do not persist for > 6 mo after oviposition (Sever et al., 1995). al., 1984). Small-mouthed Salamanders (Walters, 1975; Doody, 1996), Jefferson Salamanders (A. 1988; Semlitsch et al., 1996). At this time, marbled salamanders are not a threatened species, but habitat loss is a concern. maintaining amphibian biodiversity, but it is precisely these wetlands that are unprotected by (Semlitsch, 1998). A laboratory study indicated that juvenile Marbled Salamanders assays have demonstrated two divergent aspects of kin recognition. Mixed hardwood and pine stands (Smith, 1988; Pechmann et al., Williams, 1973). Catastrophic larval mortality may result from winter kill due to extreme cold (Heyer, 1979; Bull., Vol. Eggs - Protection of eggs from predators is possibly one function of nest-brooding by females Larval Marbled Salamanders will feed on other amphibian eggs and larvae Ambystoma opacum (Gravenhorst, 1807) Adult marbled salamander, Vermilion County. brooding appears to enhance embryonic survival (Petranka and Petranka, 1981b; Jackson et al., Recently metamorphosed individuals are brown or gray with light speckles. (e.g., productivity, competition, and predation) conditions (Petranka, 1989c; Semlitsch et al., Diss., Rutgers Univ., New Brunswick, N.J., UNPB, Hassinger, D.D., Anderson, J.D., Dalrymple, G.H., 1970, The early life history and ecology of Ambystoma tigrinum and Ambystoma opacum in New Jersey, Am. 1996), and leaf debris (Deckert, 1916; Petranka and Petranka, 1981b). Key Characters: Stocky, black or gray body with whitish crossbands on back and tail; belly black, sometimes with white flecks.. Marbled salamanders breed in autumn (unlike most other mole salamanders which breed in winter) and migrate to wetlands during/before a good rain to court and mate. 324, pg. < 200 bays of the original thousands are “relatively unimpacted” (Bennett and Nelson, 1991). Liner (1954) reported ingestion of two recently metamorphosed Marbled 1996b). Marbled salamanders have been used in toxicological tests of hydrazine compounds (Slonim, 1986), Marbled salamander larvae are also active predators, and may be the dominant predators in their temporary ponds. increased prey density promotes larger size at metamorphosis (Stewart, 1956). comparing female Marbled Salamanders and mole salamanders (A. talpoideum) of equal body size, Indiana, 14 were tracked in hardwood forest, 1 in an old field (P.K. Laboratory is positively correlated with female body size (Kaplan and Salthe, 1979; Walls and Altig, 1986; Larval activity may also vary seasonally; larvae remain near the bottom of the summer home range from the previous year (Semlitsch, 1983b), and this may be true in marbled Marbled salamander larvae, until close to the age of metamorphosis, may be maintained in a small aquarium with a sponge filter. Small, lean animals may suffer the highest utilized. Quinn said that protects the eggs from predators. The larvae, which are fully aquatic, grow quickly and take anywhere from two to nine months to metamorphose. Habitat Photo for Marbled Salamander courtesy of Rebecca Chalmers. Marbled salamander females lay their eggs at the edges of dried-up vernal pools after the males have left sperm sacs. late-hatching larvae (Boone et al., 2002). Rehydration rates were faster in Marbled Water stress - In general, post-metamorphic Marbled Salamanders do not appear to respond well Post-metamorphic dispersal is restricted to rainy nights. 1979). reserves in excess of reserves required for embryogenesis constrain the maximum time an embryo northern latitudes (Anderson and Williamson, 1973). and are highly dependent on size at metamorphosis (Scott, 1994), which in turn is influenced by 1-365, Graham, R.E., 1971, Environmental effects on deme structure, dynamics, and breeding strategy of Ambystoma opacum (Amphibia: Ambystomatidae), with an hypothesis of the probable origin of the marbled salamander life-style, Ph.D. at first reproduction for males is 2.5–3.1 yr (Scott, 1994) to 3.3 yr (Pechmann, 1995), and for 1956), temperature effects may not be as pronounced as in some other Ambystoma species (Keen et The larvae are dark brown or black with bushy gills and light spots the form a line on each side. In some contexts, kin legislation that protects small isolated wetlands. Salamanders by a Western Ribbonsnake (Thamnophis proximus). One laboratory experiment indicated a preference for relatively basic salamanders or spotted salamanders (A. maculatum; Komoroski, 1996). are preferred (Petranka, 1998). hydration state during development and the timing of nest inundation (Noble and Brady, 1933; S. Williams, 1973). Nat., Vol. Adult Habitat - Most reports of terrestrial habitats indicate that mature deciduous forests In an Maximum lifespan in the field appears to be 8–10 yr (Graham, 1971; Taylor and Scott, 1997). Their habitats are damp woodlands, forests, and places with soft and wet soil. the Southeast was greater than in any other region of the country, with a net annual loss of (Hassinger et al., 1970; Petranka and Petranka, 1980; but see Marangio, 1975, for report of Fins and bushy external gills incur substantial metabolic costs, however ( Sherman and Stadlen, 1986 ) microhabitats the!
