Retreating glaciers and the periglacial areas they vacate for organismal colonization produce a harsh environment of extreme radiation, nutrient limitations, and temperature oscillations. They provide a model system for studying mechanisms that drive establishment and early assembly of communities. Here, we synthesize more than twenty years of research at the...
Questions:
Popular methods to analyse community–trait–environment relationships constrain community patterns by trait and environment relationships. What if some traits are strongly associated with community composition but unrelated to environmental variables and vice versa? We take a different approach, unconstrained by this assumption using non-parametric methods. We applied this technique to...

Questions: Mountain systems have high abiotic heterogeneity over local spatial
scales, offering natural experiments for examining plant species invasions. We
ask whether functional groupings explain non-native species spread into native
vegetation and up elevation gradients.We examine whether non-native species
distribution patterns are related to environmental variables after controlling for
elevation...

The effects of exotic species invasions on biodiversity vary with spatial scale, and documentation of local-scale changes in biodiversity following invasion is generally lacking. Coupling long-term observations of local community dynamics with experiments to determine the role played by exotic species in recruitment limitation of native species would inform both...
Phylogenetic analyses of assemblage membership provide insight into how
ecological communities are structured. However, despite the scale-dependency of many
ecological processes, little is known about how assemblage and source pool size definitions can
be altered, either alone or together, to provide insight into how ecological diversity is
maintained. Moreover, although...
