The role of corticosterone and toxicity in the antipredator behavior of the
Rough-skinned Newt (Taricha granulosa).
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.

Rough-Skinned Newt, Taricha granulosa," Copeia, vol.
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).
Rough-skinned Newts (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).
