Spatial effects on species persistence and implications for biodiversity, arXiv
 









Excerpt: Natural ecosystems are characterized by striking diversity of form and
functions and yet exhibit deep symmetries emerging across scales of space, time
and organizational complexity. Species-area relationships and species-abundance
distributions are examples of emerging patterns irrespective of the details of
the underlying ecosystem functions. Here we present empirical and theoretical
evidence for a new macroecological pattern related to the distributions of local
species persistence times, defined as the timespans between local colonizations
and extinctions in a given geographic region.
