TLDR
It is suggested that body secretions and/or faecal material may act as signal markers during territorial defence in red-backed and Shenandoah salamanders as well as in other Plethodon species.About:

Further classification of skin alkaloids from neotropical poison frogs (dendrobatidae), with a general survey of toxic/noxious substances in the amphibia
TL;DR: Cutaneous granular glands are a shared character of adult amphibians, including caecilians, and are thought to be the source of most biologically active compounds in amphibian skin, which clearly prove the defensive value of these diverse metabolites.

Dear Enemy Recognition and the Costs of Aggression between Salamanders
TL;DR: Adult male and female red-backed salamanders, Plethodon cinereus, employ "dear enemy" recognition, such that individuals are less aggressive and more submissive toward familiar territorial neighbors than toward strangers.
Journal ArticleDOI
Constraints on the Design of Chemical Communication Systems in Terrestrial Vertebrates
TL;DR: Several features of chemical signals, including temporal parameters, spatial range, localizability, intensity and detectability, and information content, appear to be adjusted for particular social functions, subject to constraints of the signaling environment.

Homing and olfaction in salmonids: a critical review with special reference to the atlantic salmon
TL;DR: Wild, native fish demonstrate an excellent homing ability, judged from percent return to the home river and straying to non‐native watersheds.
Journal ArticleDOI
Territoriality in a terrestrial salamander: the influence of resource quality and body size
TL;DR: In this natural forest habitat, there is intraspecific competition for high quality cover objects and larger individuals are more successful competitors than smaller individuals and large body size is an advantage in territorial encounters.

Spacing Patterns in Mobile Animals
Jerram L. Brown,Gordon H. Orians +1 more
TL;DR: This review will examine concepts of spacing patterns in mobile animals from the perspective of their proximate causes, their ecological consequences, and their adaptive significance.
Journal ArticleDOI
The biological significance of the territories of birds.
TL;DR: Since territorial behaviour has consequences both harmful and advantageous to the individual's chances of ultimate reproductive success, and since the inter relations between the selective forces governing behaviour, structure and physiology are extremely complex, simple answers about the function of territory cannot be expected.

Responses of olfactory bulb neurones to odour stimulation of small nasal areas in the salamander.
John S. Kauer,David G. Moulton +1 more
TL;DR: The present experiments were designed to test to what extent the position of an odour on the receptor mucosa can influence the activity of olfactory bulb neurones.

Competitive Exclusion as a Factor Influencing the Distributions of Two Species of Terrestrial Salamanders
TL;DR: The salamander Plethodon richmondi shenandoah is restricted to areas of talus on Hawksbill Mountain, Shenandoah National Park, Virginia, while P. cinereus inhabits the soil outside the talus, and it seems unlikely that salamanders other than cine reus could exclude shenandanah from the soil or that other animals exert a strong influence.

Food as a Limited Resource in Competition between Two Species of Terrestrial Salamanders
TL;DR: Salamanders in the soil take prey that are significantly larger than prey taken by conhabiting P. cinerueus, indicating that food may be the limited resource for which competition occurs, and food may periodically become a limited resource during long dry seasons and as such may affect the survival of the salamanders or their ability to produce eggs.
