▪ Abstract Mammals are exposed to a diverse array of parasites and infectious diseases, many which affect host survival reproduction. Species that live in dense populations, large social groups, or with promiscuous mating systems may be especially vulnerable diseases owing the close proximity higher contact rates among individuals. We review effects density contacts on parasite spread importance promiscuity structure for evolution sexually transmitted diseases. Host organization system...
In a wild plant-pathogen system, host resistance and pathogen virulence varied markedly among local populations. Broadly virulent pathogens occurred more frequently in highly resistant populations, whereas avirulent dominated susceptible Experimental inoculations indicated negative trade-off between spore production virulence. The nonrandom spatial distribution of pathogens, maintained through time despite high mobility, implies that selection favors strains Melampsora lini Linum marginale...
Abstract The soil environment is essential to many ecosystem services which are primarily mediated by microbial communities. Soil physical and chemical conditions altered on local global scales anthropogenic activity threatens the provision of services. Despite importance biota for function, we have limited ability predict manage community responses change. To better understand causal relationships between structure ecological argue a systems approach prediction management response...
Abstract Comparative studies investigating relationships between plant traits and species rarity commonness were surveyed to establish whether global patterns have emerged that would be of practical use in management strategies aimed at the long‐term conservation species. Across 54 studies, 94 been examined relation abundance, distribution threatened status local, regional geographical spatial scales. Most (63) yet focus more than one study. Half involved less 10 species, one‐quarter did not...
Spatial structuring is important in understanding the ecological and evolutionary dynamics of natural populations since local demes are rarely, if ever, completely isolated from neighboring demes. Plant host-pathogen interactions provide good examples coevolutionary systems where both numerical genetic have been explicitly investigated a spatial context genes under selection can be unambiguously identified. In this article, we focus on long-term studies several that span range life histories...
Studies of disease in relation to animal mating systems have focused on sexual selection and the evolution reproduction. Relatively little work has examined other aspects ecological evolutionary relationships between host social behaviour, dynamics prevalence infectious diseases; this is particularly evident with respect sexually transmitted diseases (STDs). Here, we use a simulation approach investigate rates STD spread ranging from permanent monogamy serial polygyny or polyandry complete...
The analysis of plant-pathogen interactions is a rapidly moving research field and one that very important for productive agricultural systems. focus this review on the evolution plant defence responses coevolution their pathogens, primarily from molecular-genetic perspective. It explores major types including pathogen associated molecular patterns effector triggered immunity as well forces driving evolution, such mechanisms by which lineages species evolve. Advances in our understanding...
Anthropogenic impacts increasingly drive ecological and evolutionary processes at many spatio-temporal scales, demanding greater capacity to predict manage their consequences. This is particularly true for agro-ecosystems, which not only comprise a significant proportion of land use, but also involve conflicting imperatives expand or intensify production while simultaneously reducing environmental impacts. These reinforce the likelihood further major changes in agriculture over next 30-40...
The potential for local adaptation between pathogens and their hosts has generated strong theoretical empirical interest with evidence both against reported a range of systems. We use the Linum marginale—Melampsora lini plant‐pathogen system hierarchical spatial structure to investigate patterns within metapopulation characterised by epidemic dynamics frequent extinction pathogen populations. Based on large sample sizes comprehensive cross‐inoculation trials, our analyses demonstrate...
The concept of gene‐for‐gene coevolution is a major model for research on disease resistance in crop plants. However, few theoretical or empirical studies have examined such systems natural situations, and as consequence, there little knowledge how spatial effects are likely to influence the evolution host pathogen virulence interactions. In this work, simulation approach was used investigate epidemiological genetic consequences varying dispersal metapopulation situations. results...
1 The metapopulation concept is useful when considering ecological and evolutionary dynamics of spatially structured populations. However, debate has focused on genetic variation that neutral rather than under selection. This distinction particularly important in antagonistic or co-evolutionary interactions such as host-pathogen predator-prey systems. Plant systems provide some the best examples studies which numerical have been investigated a explicit context, where genes selection can be...
Summary 1. Variation in disease resistance is a widespread phenomenon wild plant–pathogen associations. Here, we review current literature on natural associations to determine how diversity distributed at different hierarchical levels – within host individuals, populations, amongst populations the metapopulation scale and larger regional scales. 2. We find across all spatial scales examined. Furthermore, variability seems be best counter‐defence of plants against their rapidly evolving...
Network and multivariate statistical analyses were performed to determine interactions between bacterial fungal community terminal restriction length polymorphisms as well soil properties in paired woodland pasture sites. Canonical correspondence analysis (CCA) revealed that shifts composition correlated with dissolved organic carbon, while changes moisture, nitrogen phosphorus. Weighted correlation network detected two distinct microbial modules per land use. Bacterial ribotypes did not...
Understanding of plant-pathogen coevolution in natural systems continues to develop as new theories at the population and species level are increasingly informed by studies unraveling molecular basis interactions between individual plants their pathogens. The next challenge lies further integration these approaches a comprehensive picture how life history traits both players interact with environment shape evolutionary trajectories.
