Red-backed salamander
The red-backed (or redback〔) salamander (''Plethodon cinereus'') is a small, hardy woodland salamander. It inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime Provinces in Canada to Minnesota. It is also known as the eastern red-backed salamander〔Integrated Taxonomic Information System () 2012. (2012 Sept; cited 2012 Nov 26 ) Available from: www.itis.gov〕 or the northern red-backed salamander to distinguish it from the southern red-backed salamander (''Plethodon serratus''). It is one of 55 species in the genus ''Plethodon''.
==Description and ecology==
The red-backed salamander is a small (5.7 to 10.0 cm) terrestrial salamander which usually lives in forested areas under rocks, logs, bark, and other debris.〔Conant R, Collins JT. 1998. A field guide to reptiles and amphibians of eastern and central North America. Boston; Houghton Mifflin.〕 It is one of the most numerous salamanders throughout its range.〔 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.〔 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).〔 Both morphs have speckled black and white bellies.〔
The skin of red-backed salamanders was found to contain ''Lysobacter gummosus'', an epibiotic bacterium which produces the chemical 2,4-diacetylphloroglucinol and inhibits the growth of certain pathogenic fungi.
