The role of corticosterone and toxicity in the antipredator behavior of the Rough-skinned Newt
On a visit to Mount Pisgah Arboretum today, you might encounter second-graders discovering their first rough-skinned newt
with one of our volunteer nature guides, college students restoring habitat in our creek, a local expert leading a group walk to find lichens and mosses, birdwatchers exploring our oak savannahs, volunteers working together to resurface a trail, and visitors pausing to rest and reflect on a memorial bench.

We know at least one species, the rough-skinned newt
, can be fatal to humans: a person died after swallowing the creature on a dare.
It's the same poison found in a number of other creatures, including puffer fish, several types of frogs, North America's rough-skinned newt
, the blue-ringed octopus, and some other flatworms.
These include other flatworms, frogs, North America's rough-skinned newt
, and the blue-ringed octopus.
We found that occupancy of 3 amphibian species (California Red-legged Frog, Ram draytonii; Sierran Treefrog, Hyliola sierra; and Rough-skinned Newt
, Taricha granulosa) among 21 coastal-dune drainages was high, with most coastal-dune drainages occupied by all 3 species.
Inter- and intrahabitat movements of the rough-skinned newt
, Taricha torosa granulosa (Skilton).
Increased frequency and severity of developmental deformities in Rough-skinned Newt
(Taricha granulosa) embryos exposed to road deicing salts (NaCl & MgCl2).

We investigated the role of chemical-based avoidance behavior in predator-prey interactions between a toxic prey species, the Rough-skinned Newt
(Taricha granulosa), and its major predator, the Common Garter Snake (Thamnophis sirtalis).
(Taricha granulosa) were observed most frequently among all sample sites and years on Mitkof and Wrangell Islands, with CPUEs of 0.33 and 0.12, respectively (Table 3).
