Although the immediate cause of the die offs was the chytrid, climate change played a pivotal role in the extinctions. Researchers included this subtle connection in their inclusive climate-linked epidemic hypothesis, which acknowledged climatic change as a key factor in amphibian extinctions both in Costa Rica and elsewhere.
Climate change also increases both the frequency and intensity of extreme weather events, [7] which can directly wipe out regional populations of species. [8] Those species occupying coastal and low-lying island habitats can also become extinct by sea level rise. This has already happened with Bramble Cay melomys in Australia. [9]
Specific reasons for the decline may include climate change, chytridiomycosis, or volcanic activity, but the main threat is habitat destruction as logging, agricultural activities, and human settlement reduce their often tiny, fragmented ranges. Survey work is being undertaken to assess the status of these salamanders, and to better understand ...
No subpopulations of amphibians have been evaluated by the IUCN. Additionally, 1193 amphibian species (16.4% of those evaluated) are listed as data deficient , meaning there is insufficient information for a full assessment of conservation status.
Like most woodland salamanders, the Shenandoah salamander eats mites, flies, small beetles, springtails, and other soil invertebrates. [9] No direct observation of predation of the Shenandoah salamander has ever been reported, but potential predators residing within the habitat of the Shenandoah salamander include ring-necked snakes, short-tailed shrews, brown thrashers, and towhees.

The giant salamander was identified using DNA by staff at the Zoological Society of London and the Natural History Museum. Newly discovered giant salamander is ‘world’s largest amphibian ...
Alpine salamanders are not resilient to habitat changes— few terrestrial salamanders are— so risks of climate change altering their living spaces is severe. [23] Although alpine salamanders are listed as Least Concern on IUCN Red List, their numbers are decreasing. [1] Additionally, some subspecies of S. atra are in greater danger. [25]
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
