Patterns of environmental spatial structure lie at the heart of the most fundamental and
familiar patterns of diversity on Earth. Antarctica contains some of the strongest …

Extreme and remote environments provide useful settings to test ideas about the ecological
and evolutionary drivers of biological diversity. In the sub‐A ntarctic, isolation by geographic …

Nestedness analysis has become increasingly popular in the study of biogeographic
patterns of species occurrence. Nested patterns are those in which the species composition …

Aim To present a synthesis of past biogeographic analyses and a new approach based on
spatially explicit biodiversity information for the Antarctic region to identify biologically …

Questions Invasive species establish either by possessing traits, or trait trade‐offs similar to
native species, suggesting pre‐adaptation to local conditions; or by having a different suite …

Antarctica and its surrounding islands lie at one extreme of global variation in diversity.
Typically, these regions are characterized as being species poor and having simple food …

Environmental sorting, historical factors and neutral dynamics may all drive beta diversity
(change in species composition across space), but their relative importance remains …

Long-distance oceanic rafting is frequently invoked as an explanation for broad geographic
distributions of sedentary marine taxa, but evidence for this ecological process remains …

Environmental filtration and spatial processes are associated with variation in ecological
communities and biodiversity; however, their relative importance to species beta diversity at …

Aims Patterns of spatial community dissimilarity have inspired a large body of theory in
ecology and biogeography. Yet key gaps remain in our understanding of the local‐scale …
