“…Inquilines include the moth, which spends its entire life cycle in the pitcher plant leaves (Jones, ; Stephens, Santos, & Folkerts, ), and the flesh flies, which are also tightly associated with the plant leaves (Dahlem & Naczi, ). Notably, both the moth and flies are poor flyers and dispersal limited (Folkerts, ; Krawchuk & Taylor, ; Rasic & Keyghobadi, ; Stephens & Folkerts, ). In contrast, the spider species sampled here are widespread and opportunistic predators, abundant in the habitat but not dependent on S. alata , as either can be found in a variety of other microhabitat in the region.…”

Biogeographic barriers have long been implicated as drivers of biological diversification, but how these barriers influence co-occurring taxa can vary depending on factors intrinsic to the organism and in their relationships with other species. Due to the interdependence among taxa, ecological communities present a compelling opportunity to explore how interactions among species may lead to a shared response to historical events. Here we collect single nucleotide polymorphism data from five commensal arthropods associated with the Sarracenia alata carnivorous pitcher plant, and test for codiversification across the Mississippi River, a major biogeographic barrier in the southeastern United States. Population genetic structure in three of the ecologically dependent arthropods mirrors that of the host pitcher plant, with divergence time estimates suggesting two of the species (the pitcher plant moth Exyra semicrocea and a flesh fly Sarcophaga sarraceniae) dispersed synchronously across this barrier along with the pitcher plant. Patterns in population size and genetic diversity suggest the plant and ecologically dependent arthropods dispersed from east to west across the Mississippi River. In contrast, species less dependent on the plant ecologically show discordant phylogeographic patterns. This study demonstrates that ecological relationships may be an important predictor of codiversification, and supports recent suggestions that organismal trait data should be prominently featured in comparative phylogeographic investigations.

“…They are considered herbivores, where larvae are restricted to the pitchers and feed on the inner tissue of the leaf. Adult moths are often found inside the pitcher leaves during the day, and disperse to nearby pitchers within the bog at night (Stephens & Folkerts, ). Multiple mite lineages are known from this habitat, where they either scavenge on the prey mass or act as active predators (Fashing & O'Connor, ).…”

Aim:The Sarracenia alata pitcher plant and inquiline species comprise an ecological community. These inquilines span the continuum in their ecological association with the host pitcher plant, from species that contain little-to-no interaction with the plant to species that are completely dependent on the plant for their entire life cycle. We are interested in testing if degree of ecological dependence is positively correlated with a shared evolutionary history, and in identifying members of this community that display concordant phylogeographic structure.Location: Southeastern United States. Methods:We collected genome-wide sequence data from a set of arthropods that are ecologically associated with the plant to estimate comparative phylogeographic patterns among the species. We estimated species tree distributions from biallelic unlinked SNP data and used phylogeographic concordance factors (PCFs) to test degree of phylogeographic concordance among community members. In addition, for each species we conducted an analysis of molecular variance and calculated F ST values to identify population genetic structure across the landscape, and compared these traditional values to the tree-based approach.Results: Obligate members of the pitcher plant community display concordant phylogeographic patterns, suggesting their ecological dependence has manifested itself into a shared evolutionary history. In contrast, two spider species do not contain significant population genetic structure or similar phylogeographic histories, highlighting their loose association with the host pitcher plant. Main conclusion:The S. alata pitcher plant system should be considered an evolutionary community, where multiple members sharing strong ecological interactions also display concordant phylogeographic structure. This work demonstrates that PCFs provide an important quantitative measure into assessing community structure and illustrates how simulations can be used to assess significance of shared patterns of phylogeographic structure across the landscape.
