▪ Abstract Plant pathogens cause mortality and reduce fecundity of individual plants, drive
host population dynamics, and affect the structure and composition of natural plant …

Several floral microbes are known to be pathogenic to plants or floral visitors such as
pollinators. Despite the ecological and economic importance of pathogens deposited in …

Summary 1 We present a critical review of the application of metapopulation theory to the
regional dynamics of plants. We consider whether there is evidence that regional …

A recent issue of Nature contained two articles on plant pathogens. One described the
potential importance of pathogens in driving succession', while the other described a fungal …

For coevolution to occur, there must be genetic variation in each species for traits relevant to
their interaction. Here, statistically significant variation in susceptibility to a parasitic wasp …

Conventional wisdom holds that parasites evolve more rapidly than their hosts and are
therefore locally adapted, that is, better at exploiting sympatric than allopatric hosts. We …

By using models which incorporate both numerical and gene-frequency dynamics, we
investigate the conditions for a stable polymorphism in host disease resistance when there …

Variation in disease resistance is a widespread phenomenon in wild plant–pathogen
associations. Here, we review current literature on natural plant–pathogen associations to …

Plant populations are often genetically polymorphic for resistance to pathogens. The
effectiveness of this resistance is limited because the pathogens are, in turn, polymorphic for …

In the last decade, an increasing number of studies have suggested that males and females
of dioecious plants may be differentially affected by competition, herbivory, and parasitism …
