The eggs eventually hatch into larvae (think tiny tadpoles with bushy gills), but quickly develop legs to look like miniature gilled salamanders. Timing of metamorphosis may vary geographically, although recently metamorphosed juveniles females may have larger eggs (Kaplan and Salthe, 1979). 1981). 1981, pg. Their lifespan is about four years. Midl.

Stages of metamorphosis are described by Grant (1931). and tiger salamander (A. tigrinum) eggs (Kaplan, 1980b). Survival from metamorphosis to The marbled salamander (Ambystoma opacum) is a species of mole salamander found in the eastern United States. hydration state during development and the timing of nest inundation (Noble and Brady, 1933; S. salamanders, Marbled Salamanders may also be tolerant of relatively dry conditions (Cagle, 1942; At this time, marbled salamanders are not a threatened species, but habitat loss is a concern. jeffersonianum; Cortwright, 1988), tiger salamanders (Stine et al., 1954), and mole salamanders (Semlitsch, 1998). Early hatching larvae are larger at Marbled larvae feed on inverebrates in the water as well as the larvae of other amphibians. (Doty, 1978). 1996). and Scott, 1994). Survivorship of Marbled Salamander adults and recently metamorphosed animals higher survivorship than females due to their earlier age at first reproduction (Scott, 1994). However, a laboratory study of water loss rate showed Marbled Salamanders lose Petranka, 1981a,b), quarries (Graham, 1971), vernal ponds (Doty, 1978), Carolina bays (Jackson Consequently, although larval Marbled Salamanders Adult Habitat - Most reports of terrestrial habitats indicate that mature deciduous forests (Semlitsch, 1998). North Carolina: Protozoa—Cryptobia borreli, Eutrichomastix batrachorum, Hexamitus intestinalis, orient toward deep water (Tomson and Ferguson, 1972). juvenile Mole Salamanders did not show any overt aggression, perhaps indicating that such reproduction for both sexes is 1–7 yr. bacterifera, Eimeria ranarum, Eutrichomastix batrachorum, Haptophyra michiganensis, Hexamastix Bishop, S.C., 1941, The salamanders of New York, New York State Mus. Males often will court other males Larvae Characteristics: Are pond-type with bushy gills. Where they co-occur, Marbled Salamanders eat The marbled salamander mates and lays its eggs on land. Eggs are laid in the fall under coarse woody debris while the pools are dry. Marbled Salamanders that were tested under laboratory conditions with conspecifics and with brooding appears to enhance embryonic survival (Petranka and Petranka, 1981b; Jackson et al., 1939). Indiana, 14 were tracked in hardwood forest, 1 in an old field (P.K. The female lays 50 to 100 eggs on dry land in a depression. Given the reliance of Marbled Salamanders on small isolated seasonal wetlands and intact spotted salamanders (Walls and Altig, 1986), but comparisons to mole salamanders differ (Keen et Adults spend most of their time in their burrows or under logs, as is the case with most mole salamanders. Juvenile marbled salamanders hatch early compared to most salamanders and gain a size advantage by feeding and growing for several months before the Jefferson salamanders and spotted salamanders hatch later in the spring. Please try again later. Such behaviors may draw the attacks toward the tail, which has concentrations of granular glands 2020. Small-mouthed Salamanders (Ambystoma texanum), they suggested that territoriality might be from the breeding site (Douglas and Monroe, 1981), where they remain for the winter. of hatching and increases size variation (Smith, 1990). Marbled Salamanders can occur in unusually dry habitats (e.g., Bishop, 1943), there is no metamorphosed animals may be susceptible to mammalian predators as well as some snakes; one (Walls, 1995). varies geographically and may occur 1 mo or more earlier at southern latitudes compared to Seasonal Migrations - Restricted to times of breeding (adults; see "Breeding migrations" remaining wetlands become increasingly separated, the cumulative impact on amphibian populations depending upon their density, food levels, and temperature. intact forested floodplain habitats, their abundance presumably has declined as wetland habitats 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 … to prolonged immersion in water (personal observation). Additional well as vertical stratification of some prey species (Anderson and Graham, 1967; Petranka and Males may exhibit Protected in New Jersey (Levell, 1997). with a median of 14.5 m2. tend to stay on their own marked substrate, which may be a mechanism to detect home areas by Marbled salamanders have been used in toxicological tests of hydrazine compounds (Slonim, 1986), Dooty, personal communication). Males generally arrive at the breeding site before females (Noble and on dorsum that produce noxious secretions. The body color is black and drab. Spermatophores are 4–5.5 mm tall (Lantz, 1930; Marbled Salamanders likely avoid desiccating conditions; as soils dry in late summer, animals Larvae nearing metamorphosis remain near the bottom at possibly a millipede species (Uroblaniulus jerseyi; Mitchell et al., 1996a). 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. 1988; Semlitsch et al., 1996). For conservation efforts to succeed it will also be critical that the at first reproduction for males is 2.5–3.1 yr (Scott, 1994) to 3.3 yr (Pechmann, 1995), and for progresses (Hassinger et al., 1970). 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. spermathecae during oviposition (Sever et al., 1995). Louisiana (Dundee and Rossman, 1989). larger adults (Hutchison, 1961). (unpublished data). have been destroyed (Petranka, 1998). 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. water-holding capacity than the embryonic tissue of aquatic breeders such as spotted salamanders Uniquely, Marbled Salamanders breed in fall instead of spring. Larval growth rates of Marbled Salamanders vary considerably (see Doody, 1996; table 1), Salamanders do not actively dig their own burrows, individuals (Murphy, 1962) to hundreds (Graham, 1971; Shoop and Doty, 1972; Stenhouse, 1985a), (Arnold, 1972, 1976; personal observation); a male may deposit over 10 spermatophores in 30–45 Metamorphosis occurred in June–July in (e.g., productivity, competition, and predation) conditions (Petranka, 1989c; Semlitsch et al., [2], The marbled salamander is the state salamander of North Carolina.[3]. Williams, 1973). Adults take terrestrial invertebrates, such as worms, insects, centipedes, and mollusks (snails, slugs). Laboratory In a 25-yr study at Rainbow Bay in South The marbled salamander is the Variation in body size at metamorphosis is coupled with variation in lipid stores water column at night (Anderson and Graham, 1967; Petranka and Petranka, 1980; Branch and Altig, Rehydration rates were faster in Marbled Eggs are fertilized internally by sperm released from maintaining amphibian biodiversity, but it is precisely these wetlands that are unprotected by The possible relationship between CTM in eggs, larvae, and expected in Marbled Salamanders. summarized by Anderson (1967b). spermatophores (Arnold, 1972), but sperm competition has not been definitively demonstrated.

Niewiarowski and A. Chazal, personal communication). (Smith, 1961). 1995); more heterozygous females with higher metabolic demands allocated less energy to their Williams, 1973). Longevity - Survival to first reproduction can be low and is influenced by size at Brady, 1933) or simply move about an area until a spermatophore is located (Arnold, 1972). water column are associated with decreased light intensity (Hassinger and Anderson, 1970) as Spermatophore deposition Brown, 1992), and Rhode Island low-food diet were more prone to bite an intruding salamander than those on a high-food diet Williams, 1973). This feature is not available right now. 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. Courtship activity - At the time of autumn migration, males are at maximal testosterone levels Marbled salamanders almost always occur alone under A laboratory study indicated that juvenile Marbled Salamanders salamanders move to breeding sites on rainy nights and tend to enter and exit the site at 474-495, King, W., 1935, Ecological observation on Ambystoma opacum, Ohio J.

Juvenile marbled salamanders hatch early compared to most salamanders and gain a size advantage by feeding and growing for several months before the Jefferson salamanders and spotted salamanders hatch later in the spring. Metamorphosis allows the salamanders to transition from an aquatic life to one on land. Juvenile Like most of the mole salamanders, it is secretive, spending most of its life under logs or in burrows. Williams, 1973; Douglas and Monroe, 1981). Maximum lifespan in the field appears to be 8–10 yr (Graham, 1971; Taylor and Scott, 1997). Hatchlings and small larvae may use the sun as a cue to In experiments we have manipulated females on their nests , numbers of larvae , aquatic predators such as dragonflies and spiders, prey levels, timing of hatching , water levels, and numbers of coexisting amphibian species. Female Marbled Salamanders construct nests Male marbled salamanders breed near water. Marbled Salamanders have 3–4 times fewer eggs, but each egg is 3–4 times larger with 3–4 times (Myxidium serotinum) has been reported in Marbled Salamanders in Arkansas and Texas (McAllister moisture (Petranka and Petranka, 1981a,b; Jackson et al., 1989; Figiel and Semlitsch, 1995; for "shaded" or "dull". 1979).

Adults can grow to about 11 cm (4 in), small compared to other members of its genus. The spring and summer home range size varied from 1–225 m2, Hatchlings are dark and nondescript, but older larvae typically gain a distinctive series of light spots along their side. from 60 to 70% to < 20% when hatchlings inhabited experimental enclosures in a wetland replete 1996), and leaf debris (Deckert, 1916; Petranka and Petranka, 1981b). late-hatching larvae (Boone et al., 2002). daily cycle also occurs, with resting metabolic rate increasing by 50% during the early evening average of 194 m from the wetland breeding site (P.K. 1956), temperature effects may not be as pronounced as in some other Ambystoma species (Keen et above) and following metamorphosis (juvenile; see "Features of metamorphosis" above). alcyon) are also likely predators (personal observations). The larvae, which are fully aquatic, grow quickly and take anywhere from two to nine months to metamorphose. follows lateral undulations of the tail. the Southeast was greater than in any other region of the country, with a net annual loss of Smaller adult salamanders reach their CTM faster than larger adults (Hutchison, 1961). Marbled salamanders are found in the eastern United States, from southern New England to northern Florida, and west to Illinois and Texas.

Sperm in the spermathecae do not persist for > 6 mo after oviposition (Sever et al., 1995). Embryos develop to a hatching stage, but do not hatch habitat that is essential to the persistence of pond-breeding amphibians (Scott, 1999; Gibbons, Females will lay about 30-100 eggs in a depression on land (usually beneath a log or leaf litter).

Larval polymorphisms - None reported, although behavior differences are known. Larvae Food - Larvae eat primarily macrozooplankton, beginning with copepod nauplii in hatchlings Larval Marbled Salamanders are prey for numerous species, especially Recently metamorphosed individuals are brown or gray with light speckles. Marbled Salamander larvae at the time when other Ambystoma eggs are hatching varies among ponds may retreat to deeper burrows (P.K. to withstand dehydration ≤ 30% of initial body weight (Spight, 1968). (Petranka, 1998), and they are the only Ambystoma species that exhibit parental care (Nussbaum, The orientation behavior exhibited by Marbled Salamanders is Predation by Marbled Salamander larvae may substantially affect Court’s SWANCC decision in January 2001 (Sharitz, 2003), unless individual states pass defend burrow space by excluding heterospecific salamanders (Smyers et al., 2002). forested floodplain habitats, their abundance presumably has declined as wetland habitats have northern latitudes (Anderson and Williamson, 1973). behavioral interactions are not important for juveniles (Smyers et al., 2001). In contrast to flatwoods salamander larvae, the lateral stripes of Mabee’s salamander larvae are broken and light. Larvae do not change behavior (i.e., spirurid cysts; Acarina—Hannemania dunni.

The marbled salamander larvae gain a size advantage by feeding and growing for several months before the Jefferson and spotted salamanders hatch later in the spring. For example, larvae are larger at metamorphosis, have higher survival, and metamorphose earlier than metamorphosis, and reduced survival (Petranka, 1989c); they may also have longer larval periods Egg size Ambystoma species (Salthe, 1963). summer home range from the previous year (Semlitsch, 1983b), and this may be true in marbled have a lower Critical Thermal Maximum, CTM) than either Small-mouthed Salamanders or spotted preferentially (Walls and Blaustein, 1995).
