dc.description.abstract | 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 whichmany biodiversitymeasures 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 terrestrialmammals 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. | en_US |
