and forbes suggest that vertical transmission of fungal mutualists
Building upon the understanding of AM-host interaction, the present review brings out that the role of AM fungi in plant invasion needs to be investigated in light of following three paradigms: (a) is invasiveness of introduced species in non-native habitats due to their establishment of new symbiotic relationships with AM fungi that are native to the invaded region which contributes to fitness of alien species (b) do AM fungal symbionts get transported and introduced along with propagules of alien plant species and whether the AM fungi act as pathogens to native species or as superior mutualists
in non-native habitats and confer additional benefits and (c) whether cessation of symbiotic associations in the non-native habitats decrease the invasiveness of introduced species.
As the Mutualist
Carson writes, "Because of our fondness for free markets, mutualists
sometimes fall afoul of those who have an aesthetic affinity for collectivism, or those for whom 'petty bourgeois' is a swear word.
may not punish or goad substandard partners at all, treating them just as a nuisance to live with.
Others examine issues that cut across taxonomic categories, such as evolutionary patterns and paces in bacterial mutualists
and parasites, modeling microbial virulence, pathogenomics of bacterial biothreat agents, the impact of phages on the evolution of bacterial pathogenicity, bacterial cell wall biosynthesis, and intracellular pathogens.
," (80) with some examples being the trees
All the other species, for the time being, are here considered commensalistic due to lack of information regarding their feeding habits--if they are shown to feed, even occasionally, on the rats' ectoparasites (mites and fleas primarily) then they would become mutualists
Natural selection, in contrast, fine-tunes adaptations of both sexes to the dynamic changes that occur constantly in the biotic and abiotic environment, such as changing virulence of pathogens and parasites, changing relationships between mutualists
, changing immune system challenges to pathogens, changing climate, and changing food availability.
The combination of potentially novel mycorrhizal utilization and the short co-evolutionary history exotic plants have with native mycorrhizal mutualists
suggests that these plants could receive unusually high benefits or extremely high costs their introduced ranges (Richardson et al.
Pudlo and others (1980) suggest that disturbance of a forest habitat decreases the diversity of ant fauna, including the numbers of seed-dispersing species, which eventually leads to a reduction in myrmecochorous plant species because of the loss of their seed-dispersing mutualists
These forgotten pollinators are keystone mutualists
