“…The tailed frog genus, Ascaphus, is endemic to the Pacific Northwest o f North America and inhabits the cold-flowing streams associated with those forests (Brown 1975;Wallace and Diller 1998;Bury and Adams 1999;Ritland et al 2000;Wahbe et al 2004;Matsuda and Richardson 2005;Hayes et al 2006). There are 2 species within North America, Ascaphus montanus and A. truei.…”

“…Past research on the biology and ecology o f A. truei has focused on the larval life stage (Bury and Adams 1999;Dupuis and Steventon 1999;Wahbe and Bunnell 2001;Hayes et al 2006;Burkholder and Diller 2007). As such, this species is known to be associated with mountainous lotic environments flowing through old-growth stands containing a well-vegetated understory (Green and Campbell 1984).…”

“…Past research on Ascaphus has focused on interior rocky mountain and southern populations (Daugherty and Sheldon 1982;Wahbe et al 2000Wahbe et al , 2004Matsuda and Richardson 2005;Hayes et al 2006;Burkholder and Diller 2007;Hawkes and Gregory 2012) with less work at their northern extent (Dupuis and Steventon 1999). Given the observed declines of southern populations following anthropogenic disturbances (Hawkins et al 1988;Bull and Carter 1996;Hawkes and Gregory 2012), there is concern that tailed frogs at the northern extent o f their distribution may also be negatively affected by activities such as forest harvesting, stream diversion, or the creation o f linear corridors.…”

“…Researchers have observed that southerly populations o f A. truei make seasonal large-scale movements that are dependent on life-history requirements. Furthermore, those movements and ultimately population distribution may be influenced by environmental conditions that act as a physiological or ecological constraint (Matsuda and Richardson 2005;Hayes et al 2006). Thus, in Chapter 2, I used pitfall capture data and an Information Theoretic Model Comparison (ITMC) approach to test hypotheses predicting the distribution of populations o f tailed frogs within a site relative to temporal, environmental, and treatment variables.…”

“…Pitfalltrap data have limited utility for addressing such questions as movement and distribution are premised on recaptures, which are low for this species (Maxcy 2000;Wahbe et al 2004;Matsuda and Richardson 2005;Hayes et al 2006). This is the first study to use radio The mean annual precipitation for this region is 2228 mm, approximately 40-50% o f which is snowfall at the northern extent o f the zone (Pojar et al 1991).…”

Adaptive plasticity in thermal tolerance traits may buffer organisms against changing temperatures, making such responses of particular interest in the face of global climate change. Although population variation is integral to the evolvability of this trait, many studies inferring proxies of physiological vulnerability from thermal tolerance traits extrapolate data from one or a few populations to represent the species. Estimates of physiological vulnerability can be further complicated by methodological effects associated with experimental design. We evaluated how populations varied in their acclimation capacity (i.e., the magnitude of plasticity) for critical thermal maximum (CTmax) in two species of tailed frogs (Ascaphidae), cold‐stream specialists. We used the estimates of acclimation capacity to infer physiological vulnerability to future warming. We performed CTmax experiments on tadpoles from 14 populations using a fully factorial experimental design of two holding temperatures (8 and 15°C) and two experimental starting temperatures (8 and 15°C). This design allowed us to investigate the acute effects of transferring organisms from one holding temperature to a different experimental starting temperature, as well as fully acclimated responses by using the same holding and starting temperature. We found that most populations exhibited beneficial acclimation, where CTmax was higher in tadpoles held at a warmer temperature, but populations varied markedly in the magnitude of the response and the inferred physiological vulnerability to future warming. We also found that the response of transferring organisms to different starting temperatures varied substantially among populations, although accounting for acute effects did not greatly alter estimates of physiological vulnerability at the species level or for most populations. These results underscore the importance of sampling widely among populations when inferring physiological vulnerability, as population variation in acclimation capacity and thermal sensitivity may be critical when assessing vulnerability to future warming.
