“…Yan et al () and Liang et al () uncovered seven divergent mitochondrial clades in A. davidianus . Besides, Riddell, Odom, Damm, and Sears () revealed that plasticity may contribute in buffering salamander species from climate change. Models not accounting for plasticity may overestimate a species' extinction risk.…”

Being the largest extant amphibian in the world, the IUCN Critically Endangered Chinese giant salamander Andrias davidianus is a charismatic species with great international public interest. While threats such as commercial overexploitation and habitat degradation have been extensively documented to affect natural populations of A. davidianus, still no information is available about the species sensitivity to climate change. Here, we develop an ensemble of species distribution models (SDMs) for A. davidianus and projected its habitat suitability under present‐day and future climate change scenarios. We based our SDMs on bioclimatic and topographic predictors, and recent (2012–2018) field‐collected occurrence data across the whole distribution range of the species. The ensemble SDMs exhibited good predictive capacity and suggested that slope, maximum temperature of warmest month, precipitation of driest month, and isothermality are the most influential predictors in determining distribution patterns in this species. The projections of our models point to a pronounced impact of climate changes over A. davidianus, with more than two‐thirds of its suitable range expected to be lost in all scenarios of future climates tested. In concert with the numerous other threats that are affecting this species, climate change poses a serious hindrance to the long‐term survival of A. davidianus. We emphasise the urgent need of undertaking strict measures to manage this species and safeguard the few remaining available suitable habitats. We suggest that adaptive management strategies including designation of new reserves should be considered to mitigate the impacts of climate change on A. davidianus.

“…For one species (the Rough-skinned Newt, Taricha granulosa), individuals occupying a coastal stream on the Pacific Coast of North America varied in their physiological tolerance to elevated salinity, with individuals closer to the ocean exhibiting less of a response to salt stress than those found farther upstream(Hopkins et al, 2016). Physiological plasticity is a significant means by which species may persist across varying environmental conditions(Chevin & Hoffmann, 2017;Herrando-Pérez et al, 2018;Novarro et al, 2018).Ultimately, plasticity may buffer some species from extinction by promoting physiological, behavioral, and/or other adaptations that could minimize potentially lethal exposure to stressors such as salinity(Chown et al, 2010;Riddell, Odom, Damm, & Sears, 2018;Sergio, Blas, & Hiraldo, 2018;Urban, Richardson, & Freidenfelds, 2014).…”

Climate change is anticipated to exacerbate the extinction risk of species whose persistence is already compromised by habitat loss, invasive species, disease, or other stressors. In coastal areas of the southeastern United States (USA), many imperiled vertebrates are vulnerable to hurricanes, which climate models predict to become more severe in the 21st century. Despite this escalating threat, explicit adaptation strategies that address hurricane threats, in particular, and climate change more generally, are largely underrepresented in recovery planning and implementation. We provide a basis for stronger emphasis on strategic planning for imperiled species facing the increasing threat of catastrophic hurricanes. Our reasoning comes from observations of short‐term environmental and biological impacts of Hurricane Michael, which impacted the Gulf Coast of the southeastern USA in October 2018. During this storm, St. Marks National Wildlife Refuge, located along the northern Gulf of Mexico's coast in the panhandle region of Florida, received storm surge that was 3.0–3.6 m (NAVD88) above sea level. Storm surge pushed sea water into some ephemeral freshwater ponds used for breeding by the federally threatened frosted flatwoods salamander (Ambystoma cingulatum). After the storm, specific conductance across all ponds measured varied from 80 to 23,100 µS/cm, compared to 75 to 445 µS/cm in spring 2018. For 17 overwashed wetlands that were measured in both spring and fall 2018, posthurricane conductance observations were, on average, more than 90 times higher than in the previous spring, setting the stage for varying population responses across this coastal landscape. Importantly, we found live individual flatwoods salamanders at both overwashed and non‐overwashed sites, although we cannot yet assess the demographic consequences of this storm. We outline actions that could be incorporated into climate adaptation strategies and recovery planning for imperiled species, like A. cingulatum, that are associated with freshwater coastal wetlands in hurricane‐prone regions.

“…When environmental temperature changes, animals can respond by behaviourally thermoregulating (including migration, seeking shade or panting) (Walther et al 2002;Sunday et al 2010;Campbell et al 2018), they can adapt over many generations (Fields et al 1993;Hendry and Kinnison 1999;Kinnison and Hendry 2001;Parmesan and Yohe 2003;Root et al 2003;Charmantier et al 2004;Gienapp et al 2008), or they can acclimate, by shifting their thermal performance curves to better match environmental temperatures (Wilson and Franklin 2002;Riddell et al 2018;Rohr et al 2018). Thermal acclimation, a form of reversible plasticity, occurs when an organism shifts their underlying physiology in response to a change in environmental temperature to maintain physiological function (Wilson and Franklin 2002;Beaman et al 2016) (Fig 1.2).…”

“…The ability B. cocosensis has to acclimate may buffer them from increased temperatures associated with climate change, and some studies suggest that plasticity is already protecting some species from climate warming (Rohr et al 2018;Riddell et al 2018). Extreme heat events, however, are predicted to result in local population extinctions , as rate of thermal change is likely to be faster than rates of physiological change/acclimation (Peck et al 2009).…”
