Correlational ecological niche models have seen intensive use and exploration as a means
of estimating the limits of actual and potential geographic distributions of species, yet their …

Aim The degree to which a species is predictably encountered within its range varies
tremendously across species. Understanding why some species occur less frequently within …

Two of the most prominent explanations for a positive interspecific relationship between
local abundance and regional distribution are the resource breadth and the resource …

Large-scale patterns of spatial variation in species geographic range size are central to
many fundamental questions in macroecology and conservation biology. However, the …

Understanding variation in abundance within species' ranges is fundamental for ecological
and evolutionary theory and applied conservation science. The abundant‐center model …

To quantify the magnitude and pattern of spatial variation in local population density within a
single species, we analyzed large numbers of samples, representing a large geographic …

The development of quantitative models of species' distributions has largely ignored the
potential for intraspecific variation in species' niche requirements. Application of such …

Understanding the processes that underlie how birds select and use habitats depends on an
accurate representation of the patterns of habitat occupancy. These patterns are sensitive to …

Ecologists seek to understand patterns of distribution and abundance of species. Studies of
distribution often use occurrence data to build models of the environmental niche of a …

A forest-simulation model was used to generate an extensive, yet detailed, data set
comprising tree size classes measured on a 9-ha area of contiguous forest over a period of …
