Gridded temperature data sets are typically produced at spatial resolutions that cannot fully resolve fine‐scale variation in surface air temperature in regions of complex topography. These data limitations have become increasingly important as scientists and managers attempt to understand and plan for potential climate change impacts. Here, we describe the development of a high‐resolution (250 m) daily historical (1979–2012)...

Aim Determine if differences in the climatic niche between conspecific adult and juvenile trees of the western U nites S tates vary by species traits and to assess if forest canopies moderate the sensitivity of juvenile trees to climatic variation. Location The western U nites S tates. Methods Using data from the USDA F orest I nventory and A nalysis programme, we compare the distribution of conspecific adult and juvenile tree...

Forests dominated by Douglas‐fir and western hemlock in the Pacific Northwest of the United States have strongly influenced concepts and policy concerning old‐growth forest conservation. Despite the attention to their old‐growth characteristics, a tendency remains to view their disturbance ecology in relatively simple terms, emphasizing infrequent, stand‐replacing (SR) fire and an associated linear pathway toward development o...

Aim The uncertainty associated with species distribution model ( SDM ) projections is poorly characterized, despite its potential value to decision makers. Error estimates from most modelling techniques have been shown to be biased due to their failure to account for spatial autocorrelation ( SAC ) of residual error. Generalized linear mixed models ( GLMM ) have the ability to account for SAC through the inclusion of a spatial...

Rapid climate change has the potential to affect economic, social, and biological systems. A concern for species conservation is whether or not the rate of on‐going climate change will exceed the rate at which species can adapt or move to suitable environments. Here we assess the climate velocity (both climate displacement rate and direction) for minimum temperature, actual evapotranspiration, and climatic water deficit (defic...
