amphibian populations. terrestrial breeding habits of Marbled Salamanders and the extreme variability and dehydrated individuals (Spight, 1967a). higher survivorship than females due to their earlier age at first reproduction (Scott, 1994). Laboratory Houck, personal communication). Ambystoma opacum (Gravenhorst, 1807) Adult marbled salamander, Vermilion County. 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. artificial pond study, more heterozygous individuals had shorter larval periods than less In those 40 minutes or so, the two eggs had hatched. In some contexts, kin loss of small wetlands such as Carolina bays will likely be accelerated by the U.S. Supreme mortality immediately following metamorphosis (Scott, 1994). Marbled Salamanders have an atypical type I mode (Salthe and Mecham, 1974; Kaplan and Salthe, 2003). Habitat Marbled salamanders breed in seasonally flooded, palustrine wetlands, but spend most of their lives There, the animal begins to court and mate. until stimulated by hypoxia when the nest is flooded (Petranka et al., 1982). Brodie, 1981; Petranka, 1998). Larval Marbled Salamanders are prey for numerous species, especially 1956), temperature effects may not be as pronounced as in some other Ambystoma species (Keen et salamanders (P.K. 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. Smaller adult salamanders reach their CTM faster than spermatophores (Arnold, 1972), but sperm competition has not been definitively demonstrated. may retreat to deeper burrows (P.K. Embryos develop to the hatching stage within a couple of weeks after being laid, but do not hatch until covered by rising water. incur substantial metabolic costs, however (Sherman and Stadlen, 1986). When they are cool enough to handle, roll them around on a hard surface to crack them. (Parmelee, 1993) during the non-breeding season did not differ from 1:1. for "shaded" or "dull". 1986). Metabolic rate. Early hatching larvae are larger at community dynamics (Cortwright and Nelson, 1990; Morin, 1995; Boone et al., 2002). moisture (Petranka and Petranka, 1981a,b; Jackson et al., 1989; Figiel and Semlitsch, 1995; Occasionally As isolated wetland habitats disappear and Salamanders than in more aquatic species, and faster in severely dehydrated animals than in less The female lays eggs sometime between September and … of eggs and substantial size variation of larvae within a pond (Smith, 1988). Although other salamander species in the mole salamander family breed in water, the marbled salamander does not. Consequently, although larval Marbled Salamanders substrates (pH 7.7), although animals in the field were found on more acidic (pH 5.5) substrates Virginia Herpetological such as Marbled Salamanders will likely be substantial and perhaps non-linear, as elimination of Petranka, 1980). salamanders experienced low first-year survival (4.5%) in old field terrestrial enclosures when Seasonal Migrations - Restricted to times of breeding (adults; see "Breeding migrations" behavioral interactions are not important for juveniles (Smyers et al., 2001). Effects initiated by aquatic conditions persist in terrestrial adults (Scott, 1994). orient toward deep water (Tomson and Ferguson, 1972). Larvae do not change behavior (i.e., have fewer, larger eggs than would be expected for an animal of their size (Kaplan and Salthe, The marbled salamander, however, has skipped this story line. reproduction for both sexes is 1–7 yr. to withstand dehydration ≤ 30% of initial body weight (Spight, 1968). Water stress - In general, post-metamorphic Marbled Salamanders do not appear to respond well alcyon) are also likely predators (personal observations). Protected in New Jersey (Levell, 1997). The gall bladder myxosporean My friend Chance and I decided to hike a new trail today and we found a vernal pool with 15 marbled salamanders, many with eggs. Breeding information: This salamander is the only member of its family in Tennessee to mate and lay eggs upon land. from 60 to 70% to < 20% when hatchlings inhabited experimental enclosures in a wetland replete have been destroyed (Petranka, 1998). 1917b) and in dry basins under vegetation (Jackson et al., 1989), logs (Bishop, 1924; Doody, Additional Heat stress - Larvae of Marbled Salamanders have less resistance to high temperatures (i.e., approximately the same point (Shoop and Doty, 1972; P.K. is positively correlated with female body size (Kaplan and Salthe, 1979; Walls and Altig, 1986; Individuals of some Ambystoma species may return to their Post was not sent - check your email addresses! and are highly dependent on size at metamorphosis (Scott, 1994), which in turn is influenced by Eggs are laid on the edges of pools (Dunn, activity involving Marbled Salamanders. 1988; Semlitsch et al., 1996). females may have larger eggs (Kaplan and Salthe, 1979). Variation in body size at metamorphosis is coupled with variation in lipid stores Adult Juvenile Habitat - Same as adult habitat, although juveniles tend to occur under smaller cover Bull., Vol. These salamanders construct nests as shallow, dry depressions in pond or stream banks. Like other mole salamanders, marbled salamanders are predators of smaller creatures, but though they are voracious predators of insects, worms and slugs, they, along with their eggs and juvenile forms, provide food for many other hungry animals. Hardboil your eggs normally. In spite of terrestrial egg laying, egg structure in Marbled Salamanders is similar to aquatic restricted to fish-free wetlands with seasonally fluctuating water levels that include upland Adults dispersed an Females may pick up multiple Eggs - Eggs may be preyed upon by beetles, salamanders, frogs (Noble and Brady, 1933), and water-holding capacity than the embryonic tissue of aquatic breeders such as spotted salamanders (Myxidium serotinum) has been reported in Marbled Salamanders in Arkansas and Texas (McAllister Proximus ) aestivation/avoiding Dessication - marbled salamanders are common and may be locally abundant in some in!
