Metabarcoding reveals a high diversity of woody host-associated Phytophthora spp. in soils at public gardens and amenity woodlands in Britain
<p>This is the demultiplexed Illumina MiSeq raw sequencing data from two 96-well plates from the following recent publication, shared with permission of the corresponding author, Sarah Green:</p> <p>Riddell <em>et al.</em> (2019). Metabarcoding reveals a high diversity of woody host-associated <em>Phytophthora</em> spp. in soils at public gardens and amenity woodlands in Britain. https://doi.org/10.7717/peerj.6931<br> <br> It consists of 244 gzipped compressed plain text FASTQ format sequence files, grouped into 122 pairs by the widely used R1 and R2 suffix. The files have been renamed to use the anonymised site numbers (1 to 14) as in the paper, see also supplementary table one for site metadata. Additionally there are two negative controls, and positive control DNA mixtures of 10 and 15 species as described in the paper.<br> </p>

CSM09 Small mammal host-parasite sampling data associated with the Consume herbivore exclusion plots across two burned and native-grazed watersheds at Konza Prairie
Data set contains summaries of the number of individuals of each species of small mammal captured (relative abundance) on each trapping grid. Each record contains date, treatment, grid, trap station, species, specimen number, recapture status, specimen disposition, external body measurements (where applicable), reproductive information, and miscellaneous associated comments. These sampling records are based on nightly captures during one 4-night trapping period in fall (October concurrent with annual bison roundup activites) for each of 4 permanent trapping grids established on two fire/grazing treatments (two grids per treatment). These treatments are both grazed by native grazers (bison) and include one treatment burned annually (N1A) and one treatment burned every 4 years (N4B). In each treatment, sampling grids are arranged as 5 x 10 permanent stakes spaced 10m apart and labeled numerically between 1-50 for grid A and 51-100 for grid B. One grid per treatment (grid A) is sampled using capture-mark-release methods and the other grid in each treatment (grid B) is sampled using specimen removal and subsequent whole body processing and curation.
Phylogenetic signals in host-parasite associations for Neotropical bats and Nearctic desert rodents
<p>Hosts and their parasites have strong ecological and evolutionary relationships, with hosts representing habitats and resources for parasites. In the present study, we use approaches developed to evaluate the statistical dependence of species trait values on phylogenetic relationships to determine whether host–parasite relationships (i.e. parasite infections) are contingent on host phylogeny. If host–parasite relationships are contingent on the ability of hosts to provide habitat or resources to parasites, and if host phylogeny is an effective surrogate for among-host variation in habitat and resource quality, host–parasite relationships should evince phylogenetic signals (i.e. be contingent on host phylogeny). Because the strength of ecological relationships between parasites and their hosts may affect the likelihood of phylogenetic signals occurring in host–parasite relationships, we hypothesized that (1) host specificity would be positively correlated with the strength of phylogenetic signals and (2) the strength of phylogenetic signals will be greater for parasites that rely more on their host throughout their life cycle. Analyses were conducted for ectoparasites from tropical bats and for ectoparasites, helminths, and coccidians from desert rodents. Phylogenetic signals were evaluated for parasite presence and for parasite prevalence. The frequency of phylogenetic signal occurrence was similar for parasite presence and prevalence, with a signal detected in 24–27% of cases at the species level and in 67% and 15% of cases at the genus level for parasites of bats and rodents, respectively. No differences in signal strength or the likelihood of detecting a signal existed between groups of parasites. Phylogenetic signal strength was correlated with host specificity, suggesting that mechanisms increasing host specificity also increase the likelihood of a phylogenetic signal in host use by parasites. Differences in the transmission mode did not affect signal strength or the likelihood of detecting a signal, indicating that variation in host switching opportunities associated with the transmission mode does not affect signal strength.</p>

Bloodmeal metabarcoding of the argasid tick (Ornithodoros turicata Dugès) reveals extensive vector-host associations
<p>Molecular methods to understand host feeding patterns of arthropod vectors are critical to assess exposure risk to vector-borne disease and unveil complex ecological interactions. We build on our prior work discovering the utility of PCR-Sanger sequencing bloodmeal analysis that work well for soft ticks (<em>Acari: Argasidae</em>), unlike for hard ticks (<em>Acari: Ixodidae</em>), thanks to their unique physiology that retains prior bloodmeals for years. Here, we apply bloodmeal metabarcoding using amplicon deep sequencing to identify multiple host species in individual <em>Ornithodoros turicata</em> soft ticks collected from two natural areas in Texas, United States. Of 788 collected <em>O. turicata</em>, 394 were evaluated for bloodmeal source via metabarcoding, revealing 27 different vertebrate hosts (17 mammals, 5 birds, 1 reptile, and 4 amphibians) fed upon by 274 soft ticks. Information on multiple hosts was derived from 167 individual <em>O. turicata</em> (61%). Metabarcoding revealed mixed vertebrate bloodmeals in <em>O. turicata</em> while same specimens yielded only one vertebrate species using Sanger sequencing. These data reveal wide host range of <em>O. turicata</em> and demonstrate the value of bloodmeal metabarcoding for understanding the ecology for known and potential tick-borne pathogens circulating among humans, domestic animals and wildlife such as relapsing fever caused by <em>Borrelia turicatae</em>. Our results also document evidence of prior feeding on wild pig from an off-host soft tick for the first time in North America; a critical observation in the context of enzootic transmission of African swine fever virus if it were introduced to the US. This research enhances our understanding of vector-host associations and offers a promising perspective for biodiversity monitoring and disease control strategies.</p>
