Geography and major host evolutionary transitions shape the resource use of plant parasites

Abstract: The evolution of resource use in herbivores has been conceptualized as an analog of the theory of island biogeography, assuming that plant species are islands separated by phylogenetic distances. Despite its usefulness, this analogy has paradoxically led to neglecting real biogeographical processes in the study of macroevolutionary patterns of herbivore-plant interactions. Here we show that host use is mostly determined by the geographical cooccurrence of hosts and parasites in spider mites (Tetranychidae), a … Show more

“…Altogether, our results depict feather mites as strongly limited by transmission opportunities or highly constrained by finding similar ecological conditions on the new host, as suggested by mite species inhabiting hosts with a close phylogenetic relationship (see also Agosta & Klemens, ; Agosta, Janz, & Brooks, ; Araujo et al, ; Combes, ; Khokhlova, Fielden, Degen, & Krasnov, ; Poulin, ). Interestingly, the opposite pattern has been reported for other symbionts with much higher dispersal capabilities than feather mites, such as rodent fleas (Krasnov et al, ), tapeworm fish parasites (Bouzid et al, ) and, recently, for spider mite symbionts of plants (Calatayud et al, ). Indeed, these contrasting results within mites support that major host switches are particularly unexpected in highly specialized symbionts.…”

“…For example, the arrival of new insect species on oceanic islands, or the long‐distance dispersal of plant seeds, can result in major consequences for evolutionary radiations and global biogeography (Darwin, ; Nathan, ). Host switching (the successful colonization of a new host species by a symbiont species) falls into this category; switches are rare and difficult to detect, but because successful switches can isolate symbiont populations in new ecological contexts, they have a high potential to drive diversification of symbionts (Calatayud et al, ; Clayton, Bush, & Johnson, ; de Vienne et al, ; Hoberg & Brooks, ; Johnson, Weckstein, Meyer, & Clayton, ; Martinů et al, ; Nyman, ; Poulin, ; Ricklefs et al, ). Although symbionts constitute much of Earth's biodiversity (Dobson, Lafferty, Kuris, Hechinger, & Jetz, ; Larsen, Miller, Rhodes, & Wiens, ; Morand, ), we still lack a solid understanding of host‐switching dynamics and how it shapes symbiont evolution.…”

“…This finding has been interpreted as evidence of environmental filtering acting on the community of parasites at the “macro” scale (Krasnov et al, ). On the other hand, there is evidence that differences in parasite communities across hosts are driven by parasite geographical ranges and not phylogenetic distance, despite a strong apparent signal of phylogenetic conservatism [Calatayud et al, ; also see similar results in insect–host associations (Nylin et al, )]. The field of community phylogenetics also touches on interactions between species based on the amount of their shared evolutionary history (Cavender‐Bares, Ackerly, Baum, & Bazzaz, ; Webb et al, 2002; but see cautions in Mayfield & Levine, ).…”
