… ; Gavrilets 2003), the contraction and expansion of species geographical ranges (Kirkpatrick
& Barton 1997) and the ecological and evolutionary dynamics of species interactions (Kaltz …

… In a cross-inoculation experiment this pathogen was less successful at infecting sympatric
than allopatric hosts (Kaltz et al. unpubl./in prep.). However, restricted migration may not be …

A critical issue facing humanity is the rise in antimicrobial resistance. Although increasing
research effort is spent on developing novel drugs, few alternatives reach the clinic. Phage …

… Kaltz, unpubl. data), possibly because infected plants invest less in root stocks (Shykoff
and Kaltz 1998). Drift, together with selection for increased host plant resistance, may even …

The evolution of antibiotic resistance in bacteria is a global concern and the use of
bacteriophages alone or in combined therapies is attracting increasing attention as an alternative. …

Environmental heterogeneity influences coevolution and local adaptation in host–parasite
systems. This also concerns applied issues, because the geographic range of parasites may …

… Intuitively, the simple relationship to N o reflects the fact that we assume independence
between the fate of different lineages present at the onset of stress (no density – dependence). …

Many antagonistic interactions between hosts and their parasites result in coevolution.
Although coevolution can drive diversity and specificity within species, it is not known whether …

Environmental change represents a major threat to species persistence. When change is
rapid, a population's only means of persisting may be to evolve resistance. Understanding …
