Understanding recent biogeographic responses to climate change is fundamental for
improving our predictions of likely future responses and guiding conservation planning at both …

The populations, species, and communities in high elevation mountainous regions at or
above tree line are being impacted by the changing climate. Mountain systems have been …

Plant distributions are strongly influenced by both climate and topography. In an analysis of
geographic and topographic distributions for selected tree species in California, we found …

Dispersal—the movement of an individual from the site of birth to a different site for
reproduction—is an ecological and evolutionary driver of species ranges that shapes patterns of …

The impacts of climate change have re‐energized interest in understanding the role of
climate in setting species geographic range edges. Despite the strong focus on species' …

Heterogeneous terrain in montane systems results in a decoupling of climatic gradients.
Population dynamics across species’ ranges in these heterogeneous landscapes are shaped …

… Building on a detailed demographic study of in situ spatial gradients (Oldfather & Ackerly
2019a), we examine the effects of experimental warming and/or water addition on demographic …

Topography can create substantial environmental variation at fine spatial scales. Shaped by
slope, aspect, hill-position and elevation, topoclimate heterogeneity may increase …

Predicting whether individuals will colonize a novel habitat is of fundamental ecological
interest and is crucial to conservation efforts. A consistently supported predictor of colonization …

Fine‐scale microclimate variation due to complex topography can shape both current vegetation
distributional patterns and how vegetation responds to changing climate. Topographic …
