Ecology Letters (2011) 14: 19–28 Abstract A recent increase in studies of β diversity has
yielded a confusing array of concepts, measures and methods. Here, we provide a roadmap of …

Understanding how landscape characteristics affect biodiversity patterns and ecological
processes at local and landscape scales is critical for mitigating effects of global environmental …

Ecology Letters (2011) 14: 101–112 Abstract Biodiversity in agricultural landscapes can be
increased with conversion of some production lands into ‘more‐natural’– unmanaged or …

Conservation biological control in agroecosystems requires a landscape management
perspective, because most arthropod species experience their habitat at spatial scales beyond …

Understanding spatial variation in biodiversity along environmental gradients is a central
theme in ecology. Differences in species compositional turnover among sites (β diversity) …

Invasive species, disease vectors, and pathogens affect biodiversity, ecosystem function
and services, and human health. Climate change, land use, and transport vectors interact in …

Species diversity may be additively partitioned within and among samples (α and β diversity)
from hierarchically scaled studies to assess the proportion of the total diversity (γ) found in …

Ecologists have traditionally viewed the total species diversity within a set of communities as
the product of the average diversity within a community (alpha) and the diversity among the …

Ecologists and conservation biologists are keenly interested in how patterns of species
diversity change across spatial scales. We examined how additive partitioning can be used to …

… in both the direction and the strength of the effect of wing span among data sets could
partly be explained by a nonlinear effect of dispersal capacity on population persistence (Thomas …
