Navigating the multiple meanings of β diversity: a roadmap for the practicing ecologist.
A roadmap of the most widely used and ecologically relevant approaches for analysis through a series of mission statements is provided, distinguishing two types of β diversity: directional turnover along a gradient vs. non-directional variation. Expand
Functional landscape heterogeneity and animal biodiversity in agricultural landscapes.
A framework for solving the problem of to what extent biodiversity can be enhanced by altering landscape pattern without reducing agricultural production is proposed, considering separately compositional heterogeneity ( the number and proportions of different cover types) and configurational heterogeneity (the spatial arrangement of cover types).

Landscape moderation of biodiversity patterns and processes ‐ eight hypotheses

This review uses knowledge gained from human‐modified landscapes to suggest eight hypotheses, which it hopes will encourage more systematic research on the role of landscape composition and configuration in determining the structure of ecological communities, ecosystem functioning and services.

Partitioning Species Diversity across Landscapes and Regions: A Hierarchical Analysis of α, β, and γ Diversity

A statistical approach for testing null hypotheses that observed partitions of species richness or diversity indices differed from those expected by chance is developed, and these tests are illustrated using data from a hierarchical study of forest‐canopy beetles. Expand
Conservation biological control and enemy diversity on a landscape scale
Complex landscapes characterized by highly connected crop–noncrop mosaics may be best for long-term conservation biological control and sustainable crop production, but experimental evidence for detailed recommendations to design the composition and configuration of agricultural landscapes that maintain a diversity of generalist and specialist natural enemies is still needed. Expand
Disentangling the Drivers of β Diversity Along Latitudinal and Elevational Gradients
It is shown that sampling alone predicts changes in β diversity caused simply by changes in the sizes of species pools, and there is no need to invoke differences in the mechanisms of community assembly in temperate versus tropical systems to explain these global-scale patterns of β diversity. Expand
Additive Partitioning of Species Diversity across Multiple Spatial Scales: Implications for Regional Conservation of Biodiversity
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 statistically… Expand
Harvester Ants (Pogonomyrmex spp.): Their Community and Ecosystem Influences
Because of nest densities, the longevity of nests, and the amount of seed harvested and soil handled, harvester ants have significant direct and indirect effects on community structure and ecosystem functioning. Expand
Partitioning species diversity across landscapes and regions: a hierarchical analysis of alpha, beta, and gamma diversity.
A statistical approach for testing null hypotheses that observed partitions of species richness or diversity indices differed from those expected by chance is developed, and these tests are illustrated using data from a hierarchical study of forest-canopy beetles. Expand
Critical Thresholds in Species' Responses to Landscape Structure
Critical thresholds are transition ranges across which small changes in spatial pattern produce abrupt shifts in ecological responses. Habitat fragmentation provides a familiar example of a critical… Expand
