Aims We present the first global map of vascular plant species richness by ecoregion and
compare these results with the published literature on global priorities for plant conservation …

Societal Impact Statement Identifying regions of the world that are rich in plant species will
enable conservation efforts to be more effectively targeted. We present a review of global …

Questions The co‐existence of high numbers of species has always fascinated ecologists,
but what and where are the communities with the world records for plant species richness …

Aim To explore the scale dependence of relationships between novel measures of
geodiversity and species richness of both native and alien vascular plants. Location Great …

Documenting and understanding patterns of biodiversity is a central issue in biogeography
and macroecology. Knowledge about the distribution of biodiversity is also a central …

An important question in conservation biology is the extent to which the number of
taxonomic supraspecific categories can serve as surrogates of species richness. This issue …

Aim Recent advances in the availability of species distributional and high‐resolution
environmental data have facilitated the investigation of species richness–environment …

Species richness has, arguably, become the common currency of studies of biodiversity
(Gaston and Spicer, 1998). As is apparent from most of the multiple definitions of …

The richness pattern of native vascular plants in North America (north of Mexico) was
studied at the generic level. North America was divided into thirteen geographical regions …

We compare the numbers of vascular plant species in the three major tropical areas. The
Afrotropical Region (Africa south of the Sahara Desert plus Madagascar), roughly equal in …
