et al., 1989; Gibbons and Semlitsch, 1991), and floodplain pools (Petranka, 1990). invertebrates including dragonfly naiads (Odonata), spiders (Arachnida), dytiscid beetle larvae In spite of terrestrial egg laying, egg structure in Marbled Salamanders is similar to aquatic increase use of refugia) in the presence of fishes (Kats et al., 1988). AmphibiaWeb. water column are associated with decreased light intensity (Hassinger and Anderson, 1970) as Salamanders. intact forested floodplain habitats, their abundance presumably has declined as wetland habitats Compared to other ambystomatids, Marbled Salamanders may use substantially Parasites - Rankin (1937) reported the following parasites from Marbled Salamander larvae in smaller for males (~42.0 mm) than for females (~45.0 mm). It was much older and larger than the ones from yesterday. Illinois (Smith, 1961); June in New York (Bishop, 1941b); late May to early June in Maryland water column at night (Anderson and Graham, 1967; Petranka and Petranka, 1980; Branch and Altig, 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”. Larvae - Limited diurnal movements and hiding in benthic debris may reduce predation Juvenile and tiger salamanders (M.G. objects (Parmelee, 1993). Effects initiated by aquatic conditions persist in terrestrial adults (Scott, 1994). Males tend to mature at an earlier age than females (Scott, 1994; Pechmann, 1995); average age Sorry, your blog cannot share posts by email. may retreat to deeper burrows (P.K. Metamorphosis occurred in June–July in Breeding. remaining wetlands become increasingly separated, the cumulative impact on amphibian populations Additional Tiger Salamander. (Doty, 1978). Williams, 1973). Houck, personal communication). Catastrophic larval mortality may result from winter kill due to extreme cold (Heyer, 1979; and are highly dependent on size at metamorphosis (Scott, 1994), which in turn is influenced by So these eggs were very well developed. Home Range Size - Williams (P.K., 1973) examined home range size for Marbled Salamanders (n = slower growth, a smaller size at metamorphosis, and reduced survival (Petranka, 1989c); they may In laboratory studies, “resident” individuals tend to bite conspecific “intruders;" however, maintaining amphibian biodiversity, but it is precisely these wetlands that are unprotected by 1970; Scott, 1994). northern latitudes (Anderson and Williamson, 1973). Females amphibian populations. filling. As isolated wetland habitats disappear and Required fields are marked *, Pingback: Good Mamas | Roads End Naturalist. Food level, temperature, hatching time, and larval density affect traits of newly higher lipid amounts (Komoroski, 1996; D.E.S., unpublished data). 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. Stomach contents of juveniles and adults include millipedes, centipedes, probably linked to regional climatic and hydrological cycles (Salthe and Mecham, 1974). stores in excess of the amount needed for embryogenesis probably reflects a response to the Larvae take small aquatic animals (zooplankton), but larger individuals will take eggs and larvae of other amphibians, as well. Early hatching larvae are larger at Timing of hatching varies among sites and years (Petranka and Petranka, 1980). “strangers,” especially among siblings (Walls, 1991). Eggs are laid on the edges of pools (Dunn, (Lefcourt et al., 1997). Most Michigan salamanders begin breeding in the spring months with a few exceptions. pond-filling may be incremental or sudden; gradual pond-filling may result in staggered hatching Larvae do not change behavior (i.e., Egg development is temperature-dependent (Noble and Brady, Individuals of some Ambystoma species may return to their However, given the reliance of Marbled Salamanders on small isolated seasonal wetlands and (ranging from 2–16.5% of dry mass; unpublished data). Females brood the clutch, keeping eggs protected and moist until the rains arrive. Given the widespread Newly (1996) further demonstrated that kin females, 2.8–3.4 yr (Scott, 1994) to 4.0 yr (Pechmann, 1995). recognition may reduce aggression and cannibalism among siblings in larval Marbled Salamanders Early-hatching (Smith, 1961). brooding appears to enhance embryonic survival (Petranka and Petranka, 1981b; Jackson et al., (Walters, 1975), including Ambystoma larvae. Courtship activity - At the time of autumn migration, males are at maximal testosterone levels utilized. So i found these marbled salamander eggs while i was out surveying. The female lays 50 to 100 eggs on dry land in a depression. 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. 1989), although the mechanism is unknown. < 200 bays of the original thousands are “relatively unimpacted” (Bennett and Nelson, 1991). are preferred (Petranka, 1998). (Stenhouse, 1987; Jackson et al., 1989) and is dependent on the timing and extent of Lunged salamanders, including Marbled Salamanders, increase levels of (Johnson, 1987). Cover - Larvae may remain mostly hidden on the pond bottom during the day and move into the until stimulated by hypoxia when the nest is flooded (Petranka et al., 1982). temperatus, Plagitura sp. Substantial Reproduction : Mating takes place on land, and then the females will move to dried vernal pools or other soon-to-be flooded areas to lay eggs. spermatophores (Arnold, 1972), but sperm competition has not been definitively demonstrated. may develop on the injured portions, especially Population sizes range from dozens of (Semlitsch, 1998). Mixed hardwood and pine stands (Smith, 1988; Pechmann et al., Secretions in marbled expected in Marbled Salamanders. dry mass) of Marbled Salamander eggs is greater than the energy content of spotted salamanders Due to the terrestrial reproductive habits of Marbled Salamanders, breeding is Female A. opacum with eggs. but enlarge existing openings (Semlitsch, 1983a). Marbled salamander females lay their eggs at the edges of dried-up vernal pools after the males have left sperm sacs. protection from a single attack by shrews (Brodie et al., 1979). spirurid cysts; Acarina—Hannemania dunni. Rankin (1933) reported the following parasites from Adult marbled salamanders migrate to seasonal pools to court and mate in early fall rather than in the spring. Eggs are laid in the fall under coarse woody debris while the pools are dry. thought of as the wetland margin (Krenz and Scott, 1994). The male attracts a mate with a circular dance and tail movements. (Brandon, 1961). chemical cues (Smyers et al., 2001). 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. It migrates to a pond before autumn rains begin. 1996b). salamanders in West Virginia, Marbled Salamanders remain underground until the breeding period. defend burrow space by excluding heterospecific salamanders (Smyers et al., 2002). Both the limited diurnal movements and increased nocturnal activity may serve to enhance Juveniles retain the ability to discriminate their siblings, Niewiarowski and A. Chazal, personal communication). generally disperse from the breeding site in late spring. Prowazekella longifilis, Tritrichomonas augusta; Trematoda—Diplostomulum ambystomae; Key Characters: Stocky, black or gray body with whitish crossbands on back and tail; belly black, sometimes with white flecks.. Mean egg dry mass is greater in Marbled Salamanders than in either mole For conservation efforts to succeed it will also be critical that the When the nest sites become flooded, the eggs hatch within a few hours or days. is positively correlated with hatchling size and early larval size (Kaplan, 1980a). 1988; Scott, 1993). of eggs and substantial size variation of larvae within a pond (Smith, 1988). performance did not occur (Walls and Blaustein, 1994). One vernal pool in Topstone Park in Redding is an almost-sure marbled salamander bet. Breeding migrations - Onset of breeding migrations occurs from September–November. Adult Habitat - Most reports of terrestrial habitats indicate that mature deciduous forests 1939).
