Breeding sites are vulnerable to destruction and degradation through draining and filling, and many are being isolated by habitat fragmentation, which could eventually result in deleterious levels of inbreeding and reduced chances of reestablishment of locally extirpated populations. Thousands of local populations already have been eliminated by habitat loss, and more will be lost in the future (Petranka 1998, Miller 2024).

Bodies of water dominated by predatory fishes have been described as barriers but probably should be regarded as unsuitable habitat. For A. barbouri, a stream-pool breeder, predatory fishes appeared to act as a barrier to larval dispersal and gene flow for populations separated by as little as 500-1000 m (Storfer 1999). Highly disturbed land, such as the cleared and bedded soils of some silvicultural site preparation, may serve as an impediment to movement of A. cingulatum (Means et al. 1996), although Ashton (1998) noted the species' use of pine plantations, pastures, and three-year-old clearcuts. Such areas should be treated as unsuitable habitat rather than barriers. <br><br>MOVEMENTS: Palis's (1997b) suggested use of 3.2 km between breeding sites to distinguish breeding populations of A. cingulatum was based on Ashton's (1992) finding that individuals may move as much as 1.6 km from their breeding ponds. Ambystoma californiense sometimes migrates up to 2 km between breeding ponds and terrestrial habitat (see USFWS 2004). Funk and Dunlap (1999) found that A. macrodactylum managed to recolonize lakes after trout extirpation despite evidence of low levels of interpopulation dispersal. Based on a review of several Ambystoma species (e.g., Semlitsch 1981, Douglas and Monroe 1981, Kleeberger and Werner 1983, Madison 1997), Semlitsch (1998) concluded that a radius of less than 200 meters around a breeding pond would likely encompass the terrestrial habitat used by more than 95 percent of adults. Faccio's (2003) study of radio-tagged A. maculatum and A. jeffersonianum in Vermont supports this conclusion. In New York, all movements of A. tigrinum occurred in areas within 300 m of the nearest breeding pond (Madison and Farrand 1998). However, most studies of these salamanders had small sample sizes and/or were not designed to detect long-distance movements, so migration distance may be somewhat underestimated.<br><br>In summary, ambystomatid salamanders generally stay within a few hundred meters of their breeding pool. Due to high breeding site fidelity and limitation of breeding to pool basins, populations using different breeding sites exhibit little or no interbreeding among adults. Thus one might argue that each pool constitutes a separate occurrence or that the separation distance for suitable habitat should be the nominal minimum of 1 km. However, little is known about how frequently first-time (or experienced) breeders use non-natal pools (pools from which they did not originate) or how far they may move to such sites. Frequent colonization of new and remote habitats by at least some species suggests that dispersal movements sometimes may be longer than typical adult migration distances.

Mating often occurs before the female arrives at pond-basin nesting areas (Krenz and Scott, 1994, Herpetologica 50:46-50). Females deposit single clutches of up to about 250 eggs, which are attended by the female until the nest is flooded (female commonly deserts nest if disturbed before flooding). Larvae hatch in fall (usually) or as late as spring, depending on when rains flood the nest. Larvae metamorphose in spring or early summer and move into upland habitats. Most first-time breeders are at least a few years old. Maximum life-span is at least 11-12 years.<br/><br/>In South Carolina, reproductive success varied among different years; little or no recruitment occurred during drought periods (Pechmann et al. 1991). Food limitation may reduce individual female reproductive output (Scott and Fore 1995, Herpetologica 51:462-471).","ecologyComments":null,"habitatComments":"Marbled salamanders live in various wooded habitats, near swamps or vernal pools. They are more tolerant of dry habitats than are most salamanders and can be found on rocky bluffs and slopes and wooded sand dunes. Adults are entirely terrestrial and spend most of their time under surface objects or underground. Eggs are laid in forest depressions such as vernal pool basins and sometimes at the edges of permanent ponds, swamps, and slow-moving streams, in sites that lack standing water in late summer or early fall but are inundated by fall rains and generally hold standing water through winter and into at least early summer of the next year. Oviposition sites typically are in mineral soil beneath protective cover of leaf litter, logs, detritus, or rocks.","generalDescription":"Marbled salamanders have smooth skin with vertical grooves on each side of the torso, a broad head, and small eyes. The upper side is black with whitish or grayish bands. The belly in plain black. Juveniles are black or brown with numerous tiny light dots on the upperside. Maximum total length is about 5 inches (13 cm). Large larvae have large external gills and a conspicuous row of light spots on each sides bordered by less distinct rows The throat has dispersed, uniform dark stippling, and the chest and sides of the belly have scattered dark specks. Eggs are small separate spheres with clear jelly.","diagnosticCharacteristics":null,"speciesMarineHabitats":[],"speciesTerrestrialHabitats":[{"cagTerrHabId":-111086,"terrestrialHabitat":{"id":1,"terrestrialHabitatDescEn":"Forest - Hardwood","terrestrialHabitatDescEs":"Bosque - Madera dura","terrestrialHabitatDescFr":"Forêt — Feuillu","displayOrder":2}},{"cagTerrHabId":-111087,"terrestrialHabitat":{"id":2,"terrestrialHabitatDescEn":"Forest - Conifer","terrestrialHabitatDescEs":"Bosque - Conífera","terrestrialHabitatDescFr":"Forêt — Résineux","displayOrder":3}},{"cagTerrHabId":-111088,"terrestrialHabitat":{"id":3,"terrestrialHabitatDescEn":"Forest - Mixed","terrestrialHabitatDescEs":"Bosque - Mixto","terrestrialHabitatDescFr":"Forêt — Mixte","displayOrder":4}},{"cagTerrHabId":-111089,"terrestrialHabitat":{"id":4,"terrestrialHabitatDescEn":"Woodland - Hardwood","terrestrialHabitatDescEs":"Lote de madera - Madera dura","terrestrialHabitatDescFr":"Terrain boisé — Feuillu","displayOrder":6}},{"cagTerrHabId":-111090,"terrestrialHabitat":{"id":5,"terrestrialHabitatDescEn":"Woodland - Conifer","terrestrialHabitatDescEs":"Lote de madera - Conífera","terrestrialHabitatDescFr":"Terrain boisé — Résineux","displayOrder":7}},{"cagTerrHabId":-111091,"terrestrialHabitat":{"id":6,"terrestrialHabitatDescEn":"Woodland - Mixed","terrestrialHabitatDescEs":"Lote de madera - Mixto","terrestrialHabitatDescFr":"Terrain boisé — Mixte","displayOrder":8}},{"cagTerrHabId":-111085,"terrestrialHabitat":{"id":17,"terrestrialHabitatDescEn":"Bare rock/talus/scree","terrestrialHabitatDescEs":"Roca viva/pendiente de roca/piedras sueltas","terrestrialHabitatDescFr":"Éboulis","displayOrder":20}}],"speciesRiverineHabitats":[],"speciesPalustrineHabitats":[{"cagPalusHabId":-103206,"palustrineHabitat":{"id":1,"palustrineHabitatDescEn":"TEMPORARY POOL","palustrineHabitatDescEs":"PISCINA TEMPORAL","palustrineHabitatDescFr":"BASSIN TEMPORAIRE","displayOrder":1}},{"cagPalusHabId":-103209,"palustrineHabitat":{"id":3,"palustrineHabitatDescEn":"SCRUB-SHRUB WETLAND","palustrineHabitatDescEs":"HUMEDAL DE MATORRALES","palustrineHabitatDescFr":"FRUTICÉE HUMIDE","displayOrder":3}},{"cagPalusHabId":-103207,"palustrineHabitat":{"id":4,"palustrineHabitatDescEn":"FORESTED WETLAND","palustrineHabitatDescEs":"HUMEDAL BOSCOSO","palustrineHabitatDescFr":"TERRE HUMIDE FORESTIÈRE","displayOrder":4}},{"cagPalusHabId":-103208,"palustrineHabitat":{"id":6,"palustrineHabitatDescEn":"Riparian","palustrineHabitatDescEs":"Ribereño","palustrineHabitatDescFr":"Riverain","displayOrder":6}}],"speciesLacustrineHabitats":[],"speciesSubterraneanHabitats":[],"speciesEstuarineHabitats":[]},"primaryReference":{"id":1153425,"citation":"Nicholson, K.
