“…One exception was spring days with snow, which generally had positive effects, and this is similar to findings by Davis & Gedalof (2018), who found positive effects of winter snow cover on recruitment. The importance of microbial community in plant dynamics is also increasingly acknowledged (Castro et al, 2022), although soil fungus:bacteria ratio was not selected more than other variables in our system. Microbial communities could even be an important factor in determining species range shifts, such as favorable soil microbial composition mediating climate tolerance to promote tree seedling survival (Allsup et al, 2023).…”

“…Species show remarkable variability in their responses to climatic aspects of microhabitat (Bullied et al, 2012) and aspects of microhabitat not directly influenced by climate (Selmants et al, 2016;Castro et al, 2022) . There are no general trends, except for that diverse components of microhabitat are important for establishment (Table S1).…”

Climate change is causing geographic range shifts globally, and understanding the factors that influence species’ range expansions is crucial for predicting future changes in biodiversity. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically suitable, even though microhabitat variability could have overriding effects on local population dynamics. We aim to better understand the role of microhabitat in range shifts through its impacts on establishment by i) examining microhabitat variability along large macroclimatic gradients, ii) testing which of these microhabitat variables explain plant recruitment and seedling survival, and iii) predicting microhabitat suitability beyond species range limits. We transplanted seeds of 25 common tree, shrub, forb, and graminoid species across and beyond their current elevational ranges in the Washington Cascade Range, USA, along a large elevational gradient spanning a broad range of macroclimates. Over five years, we recorded recruitment, survival, and microhabitat characteristics rarely measured in biogeographic studies. We asked whether microhabitat variables correlate with elevation, which variables drive species establishment, and whether microhabitat variables important for establishment are already suitable beyond leading range limits. We found that only 30% of microhabitat parameters covaried in the expected way with elevation. We further observed extremely low recruitment and moderate seedling survival in our study system, and these were generally only weakly explained by microhabitat. Moreover, species and life stages responded in contrasting ways to soil biota, soil moisture, temperature, and snow duration. Microhabitat suitability predictions suggest that distribution shifts are likely to be species-specific, as different species have different suitabilities, and availabilities, of microhabitat beyond their present ranges, thus calling into question large-scale macroclimatic projections that will miss such complexities. We encourage further research on species responses to microhabitat and the inclusion of microhabitat in range shift forecasts.

Climate change is causing geographic range shifts globally, and understanding the factors that influence species' range expansions is crucial for predicting future biodiversity changes. A common, yet untested, assumption in forecasting approaches is that species will shift beyond current range edges into new habitats as they become macroclimatically suitable, even though microhabitat variability could have overriding effects on local population dynamics. We aim to better understand the role of microhabitat in range shifts in plants through its impacts on establishment by 1) examining microhabitat variability along large macroclimatic (i.e. elevational) gradients, 2) testing which of these microhabitat variables explain plant recruitment and seedling survival, and 3) predicting microhabitat suitability beyond species range limits. We transplanted seeds of 25 common tree, shrub, forb and graminoid species across and beyond their current elevational ranges in the Washington Cascade Range, USA, along a large elevational gradient spanning a broad range of macroclimates. Over five years, we recorded recruitment, survival, and microhabitat (i.e. high resolution soil, air and light) characteristics rarely measured in biogeographic studies. We asked whether microhabitat variables correlate with elevation, which variables drive species establishment, and whether microhabitat variables important for establishment are already suitable beyond leading range limits. We found that only 30% of microhabitat parameters covaried with elevation. We further observed extremely low recruitment and moderate seedling survival, and these were generally only weakly explained by microhabitat. Moreover, species and life stages responded in contrasting ways to soil biota, soil moisture, temperature, and snow duration. Microhabitat suitability predictions suggest that distribution shifts are likely to be species‐specific, as different species have different suitability and availability of microhabitat beyond their present ranges, thus calling into question low‐resolution macroclimatic projections that will miss such complexities.
