Data from: Using DNA barcoding to identify host-parasite interactions between cryptic species of goby (Coryphopterus: Gobiidae, Perciformes) and parasitic copepods (Pharodes tortugensis: Chondracanthidae, Cyclopoida)
<p>Previous work, using morphological characters, identified a generalist copepod parasite (<i>Pharodes tortugensis</i>) at high prevalence on two common gobies (C<i>oryphopterus glaucofraenum</i> and <i>C. dicrus</i>) in the British Virgin Islands (BVI). DNA barcoding subsequently revealed <i>C. glaucofraenum</i> to be three morphologically similar species (<i>C. glaucofraenum</i>, <i>C. venezuelae</i> and <i>C. tortugae</i>), casting doubt on host identities in the BVI and the classification of the parasite as a single species. Mitochondrial cytochrome c oxidase subunit I (COI) data from 67 gobies in the BVI showed that, in addition to <i>C. dicrus</i>, host gobies were a mix of <i>C. glaucofraenum</i> and <i>C. venezuelae,</i> while <i>C. tortugae</i> was unexpectedly absent from the study area. COI data (n = 70) indicated that the copepod infecting all three hosts was a single species, almost certainly <i>P. tortugensis</i>. The pharodes–coryphopterus interaction has a strong impact on host dynamics in the BVI, and a revised understanding of these dynamics must account for any differences among the three newly confirmed hosts in transmission of, and susceptibility to, the shared parasite. No other infected hosts were discovered at our sites, but <i>P. tortugensis</i> is reportedly widespread and infects 12 additional host species elsewhere. Further DNA barcoding is thus needed to test whether <i>P. tortugensis</i> is truly a widespread generalist, or instead represents a group of more specialized cryptic species.</p>
Thicker eggshells are not predicted by host egg ejection behaviour in four species of Australian cuckoo
<p>Defences of hosts against brood parasitic cuckoos include detection and ejection of cuckoo eggs from the nest. Ejection behaviour often involves puncturing the cuckoo egg, which is predicted to drive the evolution of thicker eggshells in cuckoos that parasitise such hosts. Here we test this prediction in four Australian cuckoo species and their hosts, using Hall-effect magnetic-inference to directly estimate eggshell thickness in parasitised clutches. In Australia, hosts that build cup-shaped nests are generally adept at ejecting cuckoo eggs, whereas hosts that build dome-shaped nests mostly accept foreign eggs. We analysed two datasets: a small sample of hosts with known egg ejection rates and a broader sample of hosts where egg ejection behaviour was inferred based on nest type (dome or cup). Contrary to predictions, cuckoos that exploit dome-nesting hosts (acceptor hosts) had significantly thicker eggshells relative to their hosts than cuckoos that exploit cup-nesting hosts (ejector hosts). No difference in eggshell thicknesses was observed in the smaller sample of hosts with known egg ejection rates, probably due to lack of power. Overall cuckoo eggshell thickness did not deviate from the expected avian relationship between eggshell thickness and egg length estimated from 74 bird species. Our results do not support the hypothesis that thicker eggshells have evolved in response to host ejection behaviour in Australian cuckoos, but are consistent with the hypothesis that thicker eggshells have evolved to reduce the risk of breakage when eggs are dropped into dome nests.</p>
Genomic evidence for contrasting patterns of host‐associated genetic differentiation across shared host‐plant species in leaf‐ and bud‐galling sawflies
<p>Resource specialization and host-associated genetic differentiation (HAD) are frequently invoked as an explanation for the high diversity of plant-feeding insects and other organisms with a parasitic lifestyle. While genetic studies have demonstrated numerous examples of HAD in insect herbivores, the general rarity of comparative studies means that we still lack an understanding of how deterministic HAD is, and whether patterns of host shifts can be predicted over evolutionary time scales. We applied genome-wide SNP data obtained through low-coverage genome resequencing to define species limits and to compare host-plant use in population samples of leaf- and bud-galling sawflies collected from seven shared willow (<em>Salix</em>) host species. To infer the repeatability of long-term cophylogenetic patterns, we also contrasted the phylogenies of the two galler groups with each other as well as with the phylogeny of their <em>Salix</em> hosts estimated based on RADseq data. We found clear evidence for host specialization and HAD in both of the focal galler groups, but also that leaf gallers are more specialized to single host species than are most bud gallers. In contrast to bud gallers, leaf gallers also exhibit statistically significant cophylogenetic signal with their <em>Salix</em> hosts. The observed discordant patterns of resource specialization and long-term host use in two related galler groups that have radiated in parallel across a shared resource base indicate a general lack of evolutionary repeatability and suggest that short- and long-term host use and ecological diversification in plant-feeding insects are dominated by stochasticity and/or lineage-specific effects.</p>
Data for: Host shift promotes divergent evolution between closely related holoparasitic species
<p>Distinct hosts have been hypothesized to possess the potential for affecting species differentiation and genome evolution of parasitic organisms. However, what host shift history is experienced by the closely related parasites and whether disparate evolution of their genomes occur remain largely unknown. Here, we screened horizontal gene transfer (HGT) events in a pair of sister species of holoparasitic Boschniakia (Orobanchaceae) having obligate hosts from distinct families to recall the former host-parasite associations and performed a comparative analysis to investigate the difference of their organelle genomes. Except these from present hosts (Ericaceae and Betulaceae), a number of HGTs from Rosaceae were identified to support the occurrence of unexpected ancient host shifts. Different hosts transfer functional genes which changed nuclear genomes of the sister species. Similarly, different donors transfer sequences to their mitogenomes which size varies due to foreign and repetitive elements rather than other factors found in other parasites. The plastomes are both severely reduced, but the extent of differences in reduction syndrome is near to the genus level. Our findings provide new insights into the genome evolution of parasites adapting different hosts and extend the mechanism of host shift promoting species differentiation to parasitic plant lineages.</p>
Data for: Host infection dynamics and disease induced mortality modify species contributions to the environmental reservoir
<p>Environmental pathogen reservoirs exist for many globally important diseases and can fuel epidemics, influence pathogen evolution, and increase the threat of host extinction. Species composition can be an important factor that shapes reservoir dynamics and ultimately determines the outcome of a disease outbreak. However, disease-induced mortality can change species communities, indicating that species responsible for environmental reservoir maintenance may change over time. Here we examine reservoir dynamics of <em>Pseudogymnoascus</em> <em>destructans</em>, the fungal pathogen that causes white-nose syndrome in bats. We quantified changes in pathogen shedding, infection prevalence and intensity, host abundance, and the subsequent propagule pressure imposed by each species over time. We find that highly shedding species are important during pathogen invasion, but contribute less over time to environmental contamination as they also suffer the greatest declines. Less infected species remain more abundant, resulting in equivalent or higher propagule pressure. More broadly, we demonstrate that high infection intensity and subsequent mortality during disease progression can reduce the contributions of high-shedding species to long-term pathogen maintenance.</p>

Field sampling and DNA-barcoding of fig pollinator wasps across host species and host developmental phase and on non-Ficus controls
<p><span>To better understand factors that might contribute to this observed range of specificity, we used sticky traps to capture fig-pollinating wasp individuals at 13 <em>Ficus</em> species, sampling at different stages of the reproductive cycle of the host figs (e.g. trees with receptive inflorescences, or vegetative trees, bearing only leaves). We also sampled at other tree species, using them as non-<em>Ficus</em> controls. DNA barcoding allowed us to identify the wasps to species, and therefore assign their presence and abundance to host fig species and the developmental stage of that individual tree. Here we upload the data and the R scripts used to analyze these data.</span></p>
