Geographic variation in genetic and demographic performance: new insights from an old biogeographical paradigm
Abstract The 'centre–periphery hypothesis'(CPH) is a long‐standing postulate in ecology
that states that genetic variation and demographic performance of a species decrease from …

Genetic variation across species' geographical ranges: the central–marginal hypothesis and beyond
There is growing interest in quantifying genetic population structure across the geographical
ranges of species to understand why species might exhibit stable range limits and to assess …

Geographic range limits: achieving synthesis
KJ Gaston - Proceedings of the Royal Society B …, 2009 - royalsocietypublishing.org
Understanding of the determinants of species' geographic range limits remains poorly
integrated. In part, this is because of the diversity of perspectives on the issue, and because …

Species are not most abundant in the centre of their geographic range or climatic niche
The pervasive idea that species should be most abundant in the centre of their geographic
range or centre of their climatic niche is a key assumption in many existing ecological …

Evolution of dispersal and mating systems along geographic gradients: implications for shifting ranges
AL Hargreaves, CG Eckert - Functional ecology, 2014 - Wiley Online Library
Dispersal affects species' ability to move or adapt in response to environmental change.
Successful long‐distance dispersal also requires reproduction in areas with few mates, thus …

Abundant‐core thinking clarifies exceptions to the abundant‐center distribution pattern
Understanding variation in abundance within species' ranges is fundamental for ecological
and evolutionary theory and applied conservation science. The abundant‐center model …

The geography of demography: long-term demographic studies and species distribution models reveal a species border limited by adaptation
VM Eckhart, MA Geber, WF Morris… - The American …, 2011 - journals.uchicago.edu
Potential causes of species' geographic distribution limits fall into two broad classes:(1)
limited adaptation across spatially variable environments and (2) limited opportunities to …

Increased seed dispersal potential towards geographic range limits in a Pacific coast dune plant
Dispersal may be favoured at geographic range edges by unstable population and
metapopulation dynamics. However, dispersal may also evolve in response to geographic …

Broad geographic covariation between floral traits and the mating system in Camissoniopsis cheiranthifolia (Onagraceae): multiple stable mixed mating systems …
Abstract Background and Aims Plants vary widely in the extent to which seeds are produced

Population genetic analysis of a recent range expansion: mechanisms regulating the poleward range limit in the volcano barnacle Tetraclita rubescens
As range shifts coincident with climate change have become increasingly well documented,
efforts to describe the causes of range boundaries have increased. Three mechanisms …
