To better understand why the fungal pathogen, Batrachochytrium dendrobatidis (Bd), varies in mortality outcome with different species, Stevenson et al. (2014) explored how host-specific body temperature at low and high elevations contribute to host Bd response. The authors incubated Bd cultures that mimicked temperatures experienced by three sympatric Litoria species, L. nannotis, L. rheocola, and L. serrata. The culture growth patterns were consistent with recovery rates in nature where the most varied thermal regime, associated with Litoria serrata at low elevation, had slower culture growth rates and a faster species recovery rate in the wild than L. nannotis and L. rheocola, which have a stable and less varied thermal regime, respectively. Their findings support the idea that natural temperature regimes affect the patterns of Bd-driven decline.
