Landscape genetics has seen rapid growth in number of publications since the term was
coined in 2003. An extensive literature search from 1998 to 2008 using keywords associated …

Publisher Summary This chapter outlines the evolution of geographic variation in birdsong.
Studies of vocal signals in birds offer potentially useful opportunities for empirical tests of the …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Darwin's finches, inhabiting the Galápagos archipelago and Cocos Island, constitute an
iconic model for studies of speciation and adaptive evolution. Here we report the results of …

Understanding the effects of landscape heterogeneity on spatial genetic variation is a
primary goal of landscape genetics. Ecological and geographic variables can contribute to …

Maintaining connectivity for broad-scale ecological processes like dispersal and gene flow
is essential for conserving endangered species in fragmented landscapes. However …

Charles Darwin's experiences in the Galápagos Islands in 1835 helped to guide his
thoughts toward a revolutionary theory: that species were not fixed but diversified from their …

Genomic comparisons of closely related species have identified “islands” of locally elevated
sequence divergence. Genomic islands may contain functional variants involved in local …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Bird beaks display tremendous variation in shape and size, which is closely associated with
the exploitation of multiple ecological niches and likely played a key role in the …
