Marine prey often occur in hierarchical mosaics whereby small, high-density patches
are nested inside of larger, lower density aggregations. We tested the extent to which the foraging
behavior of a marine predator (northern fur seal Callorhinus ursinus) could be explained by the
hierarchical patch structure of a dominant prey species...
Plant diseases often cause serious yield losses in agriculture. A pathogen’s invasiveness can be quantified by the basic reproductive number, R₀. Since pathogen transmission between host plants depends on the spatial separation between them, R₀ is strongly influenced by the spatial scale of the host distribution.We present a proof of...

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...

Ecosystems are shaped by processes occurring and interacting over multiple
temporal and spatial scales. Theory suggests such complexity can be simplified by focusing on
processes sharing the same scale as the pattern of interest. This scale-dependent approach to
studying communities has been challenged by multiscale meta-ecosystem theory, which
recognizes that...
