In New Hampshire, eastern red-backed salamanders predominate in salamander assemblages, comprising 93.5% of the biomass of six salamander species (Burton and Likens, 1975a). The number of mature ova has been positively correlated with female length (Nagel, 1977; Lotter, 1978), as well as with female mass but not length (Fraser, 1980), suggesting that low food levels or quality may reduce clutch size. Life history: Eggs are laid in June, suspended like a bunch of grapes within a rotting log or under a rock. OCLC Number: 7763502: Notes: Cover title. We conducted two experiments in microcosms to examine whether the earthworm Lumbricus terrestris acted as an ecosystem engineer by providing additional habitat (burrows) for Plethodon cinereus, a common woodland salamander. Jaeger's (1980a) data actually support Highton (2003) in suggesting stable populations over a 14-yr period prior to 1980. Eggs are susceptible to dehydration, and the rehydration rate is slower than the rate of dehydration (Heatwole, 1961b). In the United States, eastern red-backed salamanders range throughout New England, southward to western and northeastern North Carolina, and northwestward to western Minnesota, where a disjunct population is found (Petranka, 1998). L. Age/Size at Reproductive Maturity. direct-developing Plethodon is contingent on a reliable staging table from a representative species. Eastern red-backed salamanders prefer cool, moist microhabitats and avoid temperature extremes and desiccating environments (Heatwole, 1960). Ecology, 57(3):459-471. Corresponding Author. Title. Citation: AmphibiaWeb. The Red-backed can usually be found in damp locations under leaf litter or in the coarse woody debris of mature deciduous or mixed hardwood forests. Not much is known about the dispersal of neonates, although neonates and juveniles are thought to be philopatric.The spe… Females deposit eggs in moist natural cavities within leaf litter, soil burrows, or rotting logs (Test and Heatwole, 1962). Pfingsten (1989b) considers eastern red-backed salamanders to be an indicator organism of the beech-maple forest in Ohio, where cool, moist conditions prevail. 1991. The red-backed salamander is a small terrestrial salamander, 5.7–10.0 cm (2.2–3.9 in) in total length (including tail), which usually lives in forested areas under rocks, logs, bark, and other debris. Shrews ate only 40% of red-backed salamanders offered in lab trials, which was attributed to distasteful glandular secretions (Brodie et al., 1979; see also Hecker et al., 2003). The influence of habitat provisioning: use of earthworm burrows by the terrestrial salamander, Plethodon cinereus. , As in many Plethodon species, female red-backed salamanders have the ability to store sperm as spermatophore, and have been evidenced in doing so up to eight months prior to the oviposition period in June and July. Author links open overlay panel Breanna L. Riedel a Kevin R. Russell a W. Mark Ford b Katherine P. O’Neill c Harry W. Godwin c. Show more.  These color morphs are rarer than the red-backed, lead-backed, and erythristic morphs, but still have been reported with consistency among varying populations of this species. We conducted two experiments in microcosms to examine whether the earthworm Lumbricus terrestris acted as an ecosystem engineer by providing additional habitat (burrows) for Plethodon cinereus, a common woodland salamander. The egg-laying habits of Plethodon cinereus . Both species have been documented to be highly territorial both in the wild and in captivity. , Data related to Plethodon cinereus at Wikispecies, Integrated Taxonomic Information System [Internet] 2012. An Plethodon cinereus in nahilalakip ha genus nga Plethodon, ngan familia nga Plethodontidae. 4. The redback salamander, Plethodon cinereus, is one of the most abundant vertebrates in eastern North American forests, with densities often exceeding 1 per sq. They have no aquatic larval stage. Regular surface activity during prolonged warm spells in winter has been observed (Highton, 1972), and based on full stomachs in January in Indiana, there is some evidence that feeding continues through the winter (Caldwell, 1975), but declines from December–February (Petranka, 1998). (1993) hypothesized that homing was accomplished by forming a cognitive map of the surrounding pheromone-marked territories of other salamanders in the home area of the forest. A wide variety of animals and one plant will prey upon eastern red-backed salamanders, with ring-necked snakes (Diadophis punctatus) and short-tailed shrews (Blarina brevicauda) likely being the most common predators. Waldick (1997) presents evidence of mass emigration away from a clearcut in New Brunswick. None reported. Ants, termites, beetles, flies, earthworms, spiders, snails, slugs, mites, centipedes, millipedes, springtails, midges, pseudoscorpions, and other lepidopterans, thysanopterans, and hymenopterans are all reported as prey (Cockran, 1911; Murphy, 1918; Blanchard, 1928a; Hamilton, 1932; Jameson, 1944; Jaeger, 1972; Caldwell and Jones, 1973; Caldwell, 1975; Burton, 1976; Hoff, 1977; Pauley, 1978b; Mitchell and Woolcott, 1985; Bausmann and Whitaker, 1987; Maglia, 1996; Hughes et al., 1999). Eastern red-backed salamanders are replaced by the more drought resistant southern ravine salamanders (P. richmondi) on steep slopes in Ohio (Pfingsten, 1989b). The Eastern Red-backed Salamander is one of three salamanders in Vermont with very similar body sizes and shapes. In Maryland, Cooper (1956) reported aquatic hibernation in 7.5–25 cm (3–10 in) of water. In the United States, Eastern Red-backed Salamanders range throughout New England, southward to western and northeastern North Carolina, and northwestward to western Minnesota, where a disjunct population is found (Petranka, 1998). Eastern red-backed salamanders have a limited ability to burrow, being effective only in soft substrates such as leaf litter or loose humus, and they prefer to use or enlarge existing retreats (Heatwole, 1960).  This may be a consequence of a higher predation risk experienced in the wild by the lead-backed phase, and may also mean lead-phase salamanders could be more vulnerable in captivity settings. Petranka et al. Conifer-dominated forests often have litter temperatures of 39 ˚C (Heatwole, 1962), exceeding the maximum temperature tolerances for plethodontids (32.3–34.6 ˚C; Spotila, 1972), whereas litter in deciduous forests typically stays cooler (28 ˚C maximum; Heatwole, 1962). Eastern red-backed salamanders are also reported to eat their own cast skins and occasionally will cannibalize conspecific eggs and juveniles (Surface, 1913; Piersol, 1914; Burger, 1935; Heatwole and Test, 1961; Highton and Savage, 1961; Burton, 1976). Indeed, Waldick (1997) concluded that habitat modifications associated with standard forestry practices resulted in a decline of all forest amphibians in eastern North America, with terrestrial salamanders, such as eastern red-backed salamanders, being most susceptible. Despite this, eastern red-backed salamanders can be extremely numerous (see Table 12). Plethodon cinereus: red phase. However, some red-backed salamanders are thought to engage in social monogamy, and may maintain codefended territories throughout their active periods. We reared juveniles of P. cinereus in an enclosure alone, with a similarly-sized conspecific, with a similarly-sized P. glutinosus, and with a larger P. glutinosus. There is some evidence that eastern red-backed salamander black morphs can tolerate warmer temperatures than can striped morphs, and maintenance of this polymorphism may therefore increase the species' tolerance to thermal variation (Moreno, 1989). When exposed, individuals may remain motionless to avoid detection, flee for protective cover, or assume a coiled position with the tail on top, presenting a dispensable body part to the predator (see below). Predators.  Sperm or spermatophores are not retained following the oviposition period. Eastern red-backed salamanders avoid shallow soils, rocky substrates, hydric soils, and soils with pH < 3.7 (Wyman and Hawksley-Lescault, 1987; Petranka, 1998). These estimates usually do not take into account the portion of the population that remains under the surface, which is probably greater than the number of individuals on the surface (e.g., Highton, 2003).  Additional color anomalies of this species also exist, including iridistic, albino, leucistic, amelanistic, and melanistic anomalies. Small invertebrates are the staple of the diet. Class: Amphibia. In Virginia, abundance was far less in 2–7-yr-old clearcuts than in > 60-yr-old forest (Blymyer and McGinnes, 1977). In a New Hampshire study, the biomass of six species of salamanders (of which eastern red-backed salamanders comprised 93.5%) exceeded that for all birds during the nesting season and was similar to the biomass estimate for all small mammals (Burton and Likens, 1975a). Egg deposition sites. Competition between eastern red-backed salamanders and other plethodontids is recognized (e.g., Adams, 2000). Surface censuses are likely to encounter only 2–32% of the total population (Taub, 1961; Burton and Likens, 1975a; Highton, 2003). The last published embryological study of Plethodon was that of Dent (1942) who provided both a preliminary staging table and experimental evidence of thyroxine ac-tivity in the Eastern red-backed salamander Plethodon cinereus (Fig. Soil moisture, soil pH, cover object availability, and light intensity all affect salamander distribution, with soil pH being the most influential factor (Wyman, 1988a,b; Frisbie and Wyman, 1992; Sugalski and Claussen, 1997; Grover, 1998). Not much is known about the dispersal of neonates, although neonates and juveniles are thought to be philopatric.The species largely consumes invertebrates and other detritus dwellers. Placyk et al.

Plethodon cinereus (Green, 1818) Eastern Red-Backed Salamander. Seasonal Migrations. Mimicry has also been postulated as an anti-predator mechanism in the erythristic (all red) color morph of eastern red-backed salamanders, which are suspected of mimicking the red eft stage of eastern newts (Notophthalmus viridescens), a highly noxious species distasteful or poisonous to predators (Tilley et al., 1982). Ants and mites formed the bulk of the diet in a Canadian jack pine forest (Bellocq et al., 2000). Other reported predators include woodland snakes (i.e., garter snakes [Thamnophis sp. Petranka (1998) gives home area (the defended territory) averages for males, females, and juveniles as 0.16–0.33 m2. Breeding habitat. D. Juvenile Habitat. Plethodon cinereus has the widest geographical range of the genus, and possesses considerable morphological (e.g., plasticity in head shape) and behavioral variation, which may enable it to exploit a wide range of environmental conditions (Maerz et al. Institute for Tropical Ecosystem Studies, University of Puerto Rico, , 00936‐8377 San Juan, PR, USA. Plethodon cinereus ingår i släktet Plethodon och familjen lunglösa salamandrar. 1Gary S. Casper Great Lakes Ecological Services PO Box 375 Slinger, WI 53086-0375 USA firstname.lastname@example.org. Peterson et al. Forestry impacts demonstrated in other plethodontids probably apply to eastern red-backed salamanders as well, where five times more salamanders were found in Missouri old-growth stands (> 120 yr old) than in second-growth stands (70–80 yr old); 20 times more salamanders were found in second-growth stands than in regenerating forests (< 5 yr old; Herbeck and Larsen, 1999). Most brooding female eastern red-backed salamanders will desert nests and flee when approached by ring-necked snakes (Petranka, 1998). In Virginia, 95% of nests were attended by brooding females (Highton and Savage, 1961). Available density estimates are given in Table 12. There is no evidence that skin secretions from brooding females have antibiotic properties (however, see Vial and Preib, 1966; and Austin, 2000 [southern zigzag salamanders, P. ventralis]). Jaeger et al. Empirical evaluation of the hypothesis of food competition in salamanders of the genus Plethodon. habitat P. cinereus eggs found in clutches of 4 to 9 eggs either underneath or in cavities within decomposing logs. Females produce from four to 17 eggs in a year. The presence of spotted salamanders therefore can affect eastern red-backed salamander distribution on the forest floor in areas of sympatry. [ 10 ] [ 11 ] IUCN kategoriserar arten globalt som livskraftig . Eastern red-backed salamanders exhibit color variants that include red-backed and lead-backed morphs co-occurring in most populations (summarized in Petranka, 1998). Note that in the embryo in the top right egg, the tail is visible against the background of … Mid summer movements occur in response to rising temperature and falling humidity, resulting in salamanders moving to cooler, moister environments (i.e., deeper into soils and from hilltops to depressions in the forest floor; Heatwole, 1962). The results of Generalized Linear Mixed Models comparing the habitat variables that best predict the presence sites of Plethodon cinereus and P. sherando . Embryonic gills are lost just before or shortly after hatching. Brooding females do not actively forage but will eat opportunistically (Ng and Wilbur, 1995). Rita I. Cáceres‐Charneco. Eggs of this species can be confused with those of large gastropods that also nest within rotting logs. Ginklasipika han IUCN an species komo diri gud kababarak-an. McAlpine (1997a) found no evidence of decline in New Brunswick, but suggests that clearcutting, conversions to conifer plantations, and shorter cutting cycles may have depleted populations. 88073 Series: University of Toronto studies. ii. N. Feeding Behavior. These territories are defended aggressively against conspecific adults by threat displays and biting, and both males and females defend territories (Jaeger et al., 1982; Jaeger, 1984; Horne, 1988; Horne and Jaeger, 1988; Mathis, 1989, 1991; Simons et al., 1997; Lang and Jaeger, 2000; Maerz and Madison, 2000). Hatchlings are reported as 22 mm TL (Wisconsin; Vogt, 1981) and averaging 13.5 mm SVL (Ohio; Pfingsten, 1989b). Microspatial segregation occurs between eastern red-backed and Shenandoah salamanders, with possible competitive exclusion, but experimental results are inconclusive (Jaeger, 1970, 1971a,b, 1972, 1974a; Kaplan, 1977; Wrobel et al., 1980; Lancaster and Jaeger, 1995). Freshly laid ova are pale yellow to yellowish white, 3.0–4.0 mm in diameter, and surrounded by two jelly envelopes (Piersol, 1910; Cockran, 1911; Blanchard, 1928a; Bishop, 1941b; Lynn and Dent, 1941; Sayler, 1966; Nagel, 1977; Lotter, 1978; Petranka, 1998). Recent research has suggested that Plethodon cinereus may not only disperse across but also reside within open habitats including fields, meadows, and pastures.  The red-backed phase is not always red, but may actually be various other colors (e.g., yellow-backed, orange-backed, white-backed, or a rare erythristic morph in which the body is completely red). Check Google Images for Plethodon cinereus: The photographer's identification Plethodon cinereus has not been reviewed. Eastern red-backed salamanders (Plethodon cinereus) have undergone extensive taxonomic revision. Conservation. Eastern red-backed salamanders are not freeze tolerant and must avoid freezing temperatures using behavioral mechanisms (Storey and Storey, 1986). Plethodon is a genus of salamanders in the family Plethodontidae.They are also known as woodland salamanders or, more rarely, slimy salamanders. Eastern red-backed salamanders have also been found dead within the insectivorous leaves of the bog-dwelling purple pitcher plant (Sarracenia purpurea; Hughes et al., 1999). We conducted two experiments in microcosms to examine whether the earthworm Lumbricus terrestris acted as an ecosystem engineer by providing additional habitat (burrows) for Plethodon cinereus, a common woodland salamander. Other likely predators include woodland mice (Cricetidae, Zapodidae), centipedes (Chilopoda), and ground beetles (Carabidae). Kleeberger and Werner (1982) estimated home ranges in Michigan average 13 m2 for males and juveniles, 24 m2 for females. Vernberg (1955) reported soil pH preferences of 6.0–6.8. Click here to review or comment on the identification. Range maps reflecting this taxonomic change do not imply a range retraction for eastern red-backed salamanders. Managing for stand structural complexity in northern hardwood forests has been proposed as a method for promoting microhabitat characteristics important to eastern red-backed salamanders (Plethodon cinereus).We evaluated the effects of alternate, structure-based silvicultural systems on red-backed salamander populations at two research sites in northwestern Vermont. (2000) emphasize that males and females can cohabit territories as pairs and allow juveniles to forage within their territories. Eastern Red-backed Salamanders usually have a reddish-brown back with darker sides… Unusually late dates are late October in New York (Sherwood, 1895) and 2 August in northern Michigan (Davidson and Heatwole, 1960). Egg-laying behavior is described by Madison et al. O. Moisture requirements also influence microhabitat choice. This phenomenon may have implications for eastern red-backed salamander distribution as global warming progresses, because increased physiological stress is likely in warm summer periods (Ovaska, 1997). Biological series ; no. Eastern Red-backed Salamander (Plethodon cinereus: Crother, Boundy Eastern red-backed salamanders can recognize individual neighbors by odors (McGavin, 1978), and exhibit considerable site tenacity, with 91% of recaptured, displaced individuals returning to within 1 m of their capture sites in Virginia (Gergits and Jaeger, 1990). Similar to adults. Nagel (1977) reported growth rates in an eastern Tennessee population averaging 15 mm SVL during the first year and 8 mm in the second year, with growth surprisingly not slowing during the winter (females in this study reproduced annually, so growth rates may be lower in biennially reproducing populations). Monitoring protocols are being refined, and monitoring of some populations has begun (Carfioli et al., 2000). Eastern red-backed salamanders have among the highest mean rates of dehydration and rehydration (4 mg/cm2/hr) of all plethodontids (Grover, 2000). Clutch size. ... Plethodon cinereus at the Yale Peabody Museum of Natural History website; Species summary written by Kaile Burgess. (1999). E. Adult Habitat. A prolonged mating season lasts from autumn to early spring. Range/Habitat. No range retractions of eastern red-backed salamanders have been reported, but local extirpations have been due to habitat changes, chiefly deforestation, and other, unknown causes (see Highton, 2003). 2020. H. Aestivation/Avoiding Dessication. m. Given its numbers and sensitivity to habitat conditions, it may be useful as a bioindicator of environmental degradation. R. Parasites. Possible competitive interactions between eastern red-backed salamanders and valley and ridge salamanders (P. hoffmani; Fraser, 1976b), and between eastern red-backed salamanders and Wehrle's salamanders (P. wehrlei; Pauley, 1978a,b,c), have been suggested but not conclusively demonstrated. Woodland salamander - found mainly in deciduous forests, but can be found in evergreen and mixed forest as long as a moist environment exists. With the advent of freezing weather, individuals move into underground retreats, beneath stones, into ant mounds, or under and within rotting logs and stumps, where they usually remain until snowmelt (Cockran, 1911; Grizzell, 1949; Vernberg, 1953; Cooper, 1956; Sayler, 1966; Highton, 1972; Caldwell and Jones, 1973; Hoff, 1977; Lotter, 1978; Buhlmann et al., 1988). The smallest mature males from Ohio are reported to be 32–37 mm SVL, and females 34–39 mm (Pfingsten, 1989b). Eastern red-backed salamanders are aggressive toward northern slimy salamanders (P. glutinosus), defending territories against them (Lancaster and Jaeger, 1995). [updated 2012 Sept; cited 2012 Nov 26] Available from: www.itis.gov. Spotted salamanders (Ambystoma maculatum) preyed upon eastern red-backed salamanders in 9% of lab trials (Ducey et al., 1994), which might best be interpreted as interspecific interference. All members of the genus are endemic to North America (Canada and USA). Homing behavior has also been demonstrated in Michigan, where displaced salamanders returned to their territories after displacements of 30 m (90% return) and 90 m (25% return; Kleeberger and Werner, 1982). A. Selective logging appears to have less impact on this species than does clearcutting, with little difference in salamander densities detected between closed-canopy plots and 1-yr-old canopy gap plots (Messere and Ducey, 1998). C. Direct Development. They are constrained by their physiology to certain abiotic factors within their habitat, including soil moisture, temperature, leaf litter type, and cover objects. Plethodon cinereus (Eastern Red-backed Salamander) Movement. A Plethodon cinereus group has been recognized by Grobman (1944) and Highton and Larson (1979). Terrestrial . Where logging activities have reduced the number of natural cavities available in downed woody debris, females may instead utilize cavities within matted leaf litter (Petranka, 1998). Positive correlations have been made between forest age, the quantity and quality of downed woody debris, and salamander abundance (Herbeck and Larsen, 1999), and it is widely believed that abundance declined following European settlement. By Average clutch sizes are 6–9 relatively large eggs (range = 1–14). Salamanders: 232). Breeding occurs in June and July. They may also forage in bogs (Hughes et al., 1999). Habitat relationships of eastern red-backed salamanders (Plethodon cinereus) in Appalachian agroforestry and grazing systems. Maerz and Karuzas (2003) report an instance of an adult cannibalizing a juvenile. Phylum: Chordata. The incubation period is about 6–8 wk (Burger, 1935; Davidson and Heatwole, 1960; Pfingsten, 1989b), with hatching usually taking place in August–September. Sexual maturity is reached about 2 yr after hatching (Bausmann and Whitaker, 1987). Females usually remain coiled with the eggs for about 60 d until hatching, and this behavior is thought to provide some protection for the eggs from predators and dehydration (Petranka, 1998), as well as accrue energetic and growth costs to the brooding female (Ng and Wilbur, 1995). The intensity of the defense varies depending on the quality of food resources contained within the territory (Gabor and Jaeger, 1999). J. Torpor (Hibernation). Eastern red-backed salamanders are a top predator of the detritus food chain, feeding on any prey they can capture. Ecology, 57(3):459-471. Salamanders will climb on vegetation to forage at night (Cockran, 1911; Burton and Likens, 1975a; Jaeger, 1978).  Both morphs have speckled black and white bellies. Empirical evaluation of the hypothesis of food competition in salamanders of the genus Plethodon. Ovipositing typically occurs in late spring and early summer. G. Territories. Frisbie, Malcolm Pratt, and Richard L. Wyman. Related Titles. Studies suggest that populations may recover from clearcutting within 30–60 yr (Pough et al., 1987; deMaynadier and Hunter, 1995). The following parasites and protozoans have been reported from eastern red-backed salamanders (Rankin, 1937; Ernst, 1974; Muzzall, 1990; Bursey and Schibli, 1995; Muzzall et al., 1997; Bolek and Coggins, 1998): protozoans—Cryptobia borreli, Cytamoeba bacterifera, Eutrichomastix batrachorum, Haptophyra (= Cepedietta) michiganensis, Hexamastix batrachorum, Hexamitus spp., Hexamitus batrachorum, Hexamitus intestinalis, Karatomorpha swezi, Monocercomonoides sp., Monocercomonas batrachorum, Octomitus sp., Proteromonas longifila, Prowazekella longifilis, Trimitus parvus, Tritrichomonas augusta, and Tritrichomonas batrachorum; nematodes—Angiostoma plethodontis, Batracholandros magnavulvaris, Cosmocercoides dukae, Cosmocercoides variabilis, Falcaustra sp., Oswaldocruzia pipiens, Oxyuris magnavulvaris, and Rhabdias ranae; helminths—Brachycoelium hospitale, Brachycoelium louisianai, Brachycoelium obesum, Brachycoelium salamandrae, Brachycoelium storeriae, Cylindrotaenia americana, and Cylindrotaenia idahoensis. Mountain dusky salamanders (Desmognathus ochrophaeus) behave aggressively towards eastern red-backed salamanders and can drive them from occupied sites (Smith and Pough, 1994). For example, two southern subspecies (P. c. serratus and P. c. polycentratus) have been combined into southern red-backed salamanders (P. serratus; Highton and Larson, 1979). Housing. Kin discrimination between mother and offspring may be context dependent (Gibbons et al., 2003). The other two similarly-shaped salamanders in Vermont are the Four-toed and the Northern Two-lined Salamanders. As a result, P. cinereus may be well poised to undergo spatial shifts in range and abundance in response to climate change. The red-backed salamander (Plethodon cinereus) is a species of small, hardy woodland salamander in the family Plethodontidae. Historical versus Current Abundance. Fraser, Douglas F. 1976. However, in Virginia, Grover (2000) showed that eastern red-backed salamanders were displaced from moist habitats near streams and seeps by northern dusky salamanders (Desmognathus fuscus) and seal salamanders (Desmognathus monticola). 1991. , Males and females of P. cinereus typically establish separate feeding and/or mating territories underneath rocks and logs. Eastern Red-backed Salamanders (Plethodon cinereus) are one of the most abundant vertebrates in North America. i. 2007). 2. I. When territorial sites are limited, pairs of females may defend sites (Peterson et al., 2000). In this study we compare microhabitat data for a broadly distributed salamander species, Plethodon cinereus, and two microendemic species P. sherando and P. hubrichti. Males breed annually throughout the range and are sexually mature upon reaching 32–37 mm SVL (Blanchard, 1928a; Sayler, 1966; Werner, 1971; Nagel, 1977; Lotter, 1978; Petranka, 1998). In Hoff's (1977) Massachusetts study of tree stump hibernacula, a decided preference for selecting the decayed root systems of white oak (Quercus alba) over other tree species was indicated. Plethodon cinereus, redback phase, dark specimen. Habitat: Moist forests, especially forested, rocky hillsides. Their highest abundance occurs in mature hardwood forests, with deep soils and abundant downed woody debris in various stages of decomposition (Grover, 1998). Stern and Mueller (1972) reported a diurnal rhythm, as measured by oxygen consumption, with activity peaking in the early morning hours, coinciding with that time of day when the lowest temperatures and highest humidity are likely to occur. Eastern red-backed salamanders scent-mark territories on the forest floor with pheromones and fecal matter, which convey information concerning body size and gender. Our analyses evaluate two hypotheses. Family: Plethodonidae.  It is one of the most numerous salamanders throughout its range. Breeding. [ 1 ] Inga underarter finns listade i Catalogue of Life . habitat P. cinereus eggs found in clutches of 4 to 9 eggs either underneath or in cavities within decomposing logs. Eastern red-backed salamanders occupy deciduous, mixed conifer-deciduous, and sometimes northern conifer forests, where they inhabit leaf litter and utilize retreats under stones, within soil cavities, and in rotting logs. Hot, dry conditions are avoided, but true aestivation has not been recorded. F. Home Range Size. First, each of these species occupies microhabitat that differs from the available habitat. Eastern red-backed salamanders are largely nocturnal (Piersol, 1910; Cockran, 1911; Park et al., 1931; Heatwole, 1962). 1. Temperatures below 10 ˚C inhibit locomotion (Feder and Pough, 1975). Tail autotomy has also been reported as an anti-predator defense mechanism (Lancaster and Wise, 1996). A large percentage of the population may be floaters (typically smaller animals that do not hold territories); up to 49% of the animals in a Virginia study may have been floaters (Mathis, 1991). The eggs hatch in 6 to 8 weeks. Eastern red-backed salamanders possess noxious skin secretions concentrated along the dorsum of the tail (Brodie et al., 1979; Petranka, 1998), which convey protection. Order: Caudata. Highton (2003) documents recent widespread declines in most species of this complex. Reproduction is terrestrial. Adults range from 3½ – 5 inches in length.  The red-backed salamander exhibits color polymorphism and two color variations are common: the "red-backed" or "red-stripe" variety has a red dorsal stripe that tapers towards the tail, and the darker variety, known as the "lead-backed" (or simply "lead") phase, lacks most or all of the red pigmentation. Q. cit.). Soils with an interstitial relative humidity < 85% are probably unsuitable for this species (Heatwole and Lim, 1961; Heatwole, 1962). The eggs hatch in 6 to 8 weeks. Much of its life is spent underground. Eastern red-backed salamanders release alarm pheromones from skin glands when attacked, which, unlike territorial pheromones, are short lived (about 2 min; Graves and Quinn, 2000; see also Hecker et al., 2003).
