“…If mating activity in the Indiana population did commence in October, it would be interrupted by hibernation from November into March. Sever () found sperm in the Wolffian ducts of male P. cinereus in October, but Sever () did not find sperm in spermathecae of females from this locale in October. Sever () suggested that mating activity is most intense after hibernation until June, when oviposition commences.…”

Egg recognition and subsequent egg brooding are costly forms of parental investment in many species of vertebrates. Life history factors, such as coloniality or risk of brood parasitism, may constrain egg recognition in vertebrates. Female red‐backed salamanders (Plethodon cinereus) from my study site are territorial and do not share nest sites with other females. They are terrestrial and neither they nor their eggs are likely to be displaced by environmental factors such as flooding. I experimentally tested, in the laboratory, the hypothesis that female red‐backed salamanders can discriminate between their own eggs and the eggs of unfamiliar females. Each female was allowed to move about a test chamber containing two clutches of eggs, one clutch with which it was found in the forest and one that had been found with a distant female. Most females remained with one clutch of eggs, which they brooded during the entire observation period. However, they did not significantly prefer to brood their own eggs over the eggs of another female. In a corollary field experiment, I tested whether brooding females that were displaced 1 m from their nest sites would return to their territories and commence brooding behaviour within 3 d. All 10 displaced females returned to their own nest within this time period and were found brooding their eggs. Because female red‐backed salamanders at my study site do not tend to share nest sites with other females and because their eggs remain in stationary nests, selection may not have favoured egg recognition. However, the results suggest that female salamanders indirectly recognize their own eggs by actively recognizing their territorial nest sites.

 Abstract Sever, D. M., Halliday, T. R., Moriarty, E. C. and Arano, B. 2000. Sperm storage in females of the smooth newt ( Triturus v. vulgaris L.): II. Ultrastructure of the spermathecae after the breeding season. -Acta Zoologica (Stockholm) 82 : 49-56.Sperm storage in cloacal spermathecae was studied in females of Triturus v. vulgaris from southern England killed at the end of the breeding season in June. This species mates and oviposits eggs in ponds from March to June. Included in the sample were 12 unmated females collected in terrestrial situations in March and mated in the laboratory. Some of these females oviposited viable eggs in the laboratory whereas others did not oviposit after mating. In addition, we examined five females with unknown mating histories that were collected from a breeding pond in June. We found that all of the specimens contained some stored sperm and were similar in spermathecal ultrastructure. The spermathecae exhibited characteristics of secretory epithelium at the end of a cycle, including irregular heterochromatic nuclei surrounded by scant cytoplasm, absence of organelles involved in synthetic activities, few secretory vacuoles, and wide intercellular canaliculi. Spermiophagy by the spermathecal epithelium was extensive. In contrast, spermathecae from females at the beginning of the breeding season as reported in our previous study were actively producing a PAS+ secretion and did not exhibit spermiophagy. Spermiophagy is a means of eliminating sperm prior to the next breeding season.
