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 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.
Investigations on the skin toxin of the adult rough-skinned newt
, Taricha granulosa.
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.
Increased frequency and severity of developmental deformities in Rough-skinned Newt
(Taricha granulosa) embryos exposed to road deicing salts (NaCl & MgCl2).
Key words: Crater Lake National Park, Lontra canadensis, North American River Otter, predation, Rough-skinned Newt
, Taricha granulosa, tetrodotoxin
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).
In the beginning there were rough-skinned newts
and snakes who wanted to eat them.
Hoary bats, bugling elks, rough-skinned newts
, lungless salamanders, and even predaceous centipedes get equal billing with the famed spotted owl--in pictures by such eminent nature photographers as Frank Balthis, Michael Sewell, and Larry Ulrich.
Also called rough-skinned newts
, they knew well enough to move out of our way, but we had to take care not to step on them for about a quarter-mile, or more, stretch.
