Genetic information is used extensively to reconstruct the evolutionary and demographic
history of organisms. Recently, it has been suggested that genetic information from some …

A growing body of literature points to a large-scale research approach as essential for
understanding population and community ecology. Many of our advances regarding the …

Species interactions commonly coevolve as complex geographic mosaics of populations
shaped by differences in local selection and gene flow. We use a haploid matching-alleles …

Abstract The California Floristic Province harbours more endemic plant and animal taxa and
more identifiable subspecies than any other area of comparable size in North America. We …

Some species of parasites occur on a wide range of hosts while others are restricted to one
or a few host species. The host specificity of a parasite species is determined, in part, by its …

Abstract Theory predicts that mixing in spatially structured populations of hosts and parasites
can increase the rate of antagonistic coevolution. We experimentally tested this prediction by …

The geographic mosaic theory of coevolution is stimulating much new research on
interspecific interactions. We provide a guide to the fundamental components of the theory …

Morphological and molecular phylogenies of animal parasites have often shown parallel
cladogenesis, supporting hypotheses of coevolution. Few studies of the phylogenetic history …

Although much insight is to be gained through the comparison of the population genetic
structures of parasites and hosts, there are, at present, few studies that take advantage of the …

Variations observed in parasite virulence and host resistance may be the outcome of
coevolutionary processes. Recent theoretical developments have led to a 'geographic …
