“…It is important to stress that by having a PAM, almost any index of biodiversity pattern (based on incidences) can be constructed (Soberón and Cavner 2015). Total number of species becomes simply one of many aspects of the biodiversity patterns being driven by change in R.…”

“…PAMs can be estimated from the extent of occurrence maps of a group of species (Soberón and Ceballos 2011;Storch et al 2012;Vilela and Villalobos 2015). A well-sampled geographic PAM contains all of the information about species incidences and coincidences and thus, implicitly, all incidence-based indices (Soberón and Cavner 2015). Specifically, the local number of species (alpha diversity), the total number of species (gamma diversity), and their ratio, called beta diversity, are related as follows (Whittaker 1960):…”

In this work, Grinnellian niche theory (a body of theory about geographic distributions of species in terms of noninteracting niche variables) is used to demonstrate that species-area relationships emerge with both size of environmental space and size of geographic area. As environmental space increases, more species' fundamental niches are included, thus increasing the number of species capable of living in the corresponding region. This idea is made operational by proposing a size measure for multidimensional environmental space and approximating fundamental niches with minimum volume ellipsoids. This framework allows estimating a presence-absence matrix based on the distribution of fundamental niches in environmental space, from which many biodiversity measures can be calculated, such as beta diversity. I establish that Whittaker's equation for beta diversity is equivalent to MacArthur's formula relating species numbers and niche breadth; this latter equation provides a mechanism for the species-niche space relationship. I illustrate the theoretical results via exploration of niches of the terrestrial mammals of North America (north of Panama). Each world region has a unique structure of its environmental space, and the position of fundamental niches in niche space is different for different clades; therefore, species-area relationships depend on the clades involved and the region of focus, mostly as a function of MacArthur's niche beta diversity. Analyzing speciesarea relationships from the perspective of niche position in environmental space is novel, shifting emphasis from demographic processes to historical, geographic, and climatic factors; moreover, the Grinnellian approach is based on available data and is computationally feasible.

“…Richness–diversity diagrams use the presence–absence data to describe species compositions of each recorded location in a dataset. From these diagrams, it is possible to extract biodiversity indices including alpha and beta diversities (Soberón and Cavner 2015 ). The horizontal axis shows the proportional mean range size, also called the dispersal field, of the species in each location (Graves and Rahbek 2005 ).…”

The Convention on the Conservation of Migratory Species of Wild Animals (CMS) is a Multilateral Environmental Agreement (MEA) focused on species that regularly travel across international borders. Despite covering an important group of species, CMS is under-utilized compared to other conservation-focused MEAs. CMS suffers from a lack of participation across North America and most of Asia. Our goal is to illustrate differences in species richness and average range-size across signatory and nonsignatory nation-states using range–diversity plots. We also show differences in the cost of CMS membership relative to species patterns to highlight which countries may be discouraged from becoming CMS signatories. Despite containing many CMS species, large economies such as the United States, Russia, and China are not members of the convention. To facilitate migratory species conservation into the future, CMS should seek to fill gaps in participation, potentially directing recruitment efforts toward nonsignatory states that would receive the largest benefit at the lowest relative cost.

“…Biodiversity hotspots are areas featuring exceptional concentrations of endemic species while at the same time experiencing extreme loss of habitat (Brooks et al, 2006;Myers et al, 2000). Species richness and centers of endemism are critical parameters to measure the biological diversity at the macroecological scale (Arita et al, 2012;Soberon & Cavner, 2015). Thus, identifying areas with high biodiversity or conservation concerns is a crucial step toward reaching the conservation goals at global and regional scales (Burriel-Carranza et al, 2019;Sussman et al, 2019).…”
