Contrasting genome-wide signatures of selection in two closely related Epichloe plant pathogen species
<p>Deposited here composite plots for each species, each pairwise population combination and each of the seven chromosomes as shown and referred to in the manuscript.</p> <p>The filename contains [species abbrevation]_[chromosome number]_[population 1]_[population 2]. Chromosome-wide SNP data and sweeps identified for the population pair are shown. The top panel shows pairwise FST values, averaged across 5kb windows. Shaded rectangles represent the locations of AT-rich regions. The second panel shows the absolute values of the integrated haplotype score (iHS) calculated at each SNP locus for which the ancestral allele state was known. Scores for pop1 are shown at the top and scores for pop2 are negatively transformed and showed at the bottom. Horizontal dashed lines indicate the 99.9% percentile threshold which was used as a cutoff to identify outlier SNPs and inferred iHS sweeps are shown as shaded rectangles. The third panel shows the cross-population extended haplotype homozygosity (XP-EHH) scores calculated between the two populations. Dashed lines indicate 99.9% percentile threshold which was used as a cutoff to identify outlier SNPs and inferred divergent sweeps are shown as shaded rectangles. Positive and negative XP-EHH values refer to the direction of selection: positive values indicate selection in pop1 negative values indicate selection in pop2. In the bottom panel, composite likelihood ratio (CLR) scores are plotted for pop1 (black) and pop2 (blue), colored dashed lines indicate respective 99.9% threshold and colored rectangles highlight inferred CLR-sweeps.</p>

Similar parasite communities but dissimilar infection patterns in two closely related chickadee species
<p>Haemosporidian parasite communities are broadly similar in Boulder County, CO between two common songbirds –– the Black-capped Chickadee (<em>Poecile</em> <em>atricapillus</em>) and Mountain Chickadee (<em>Poecile</em> <em>gambeli</em>). However, Mountain Chickadees appear more likely to be infected with <em>Plasmodium</em> and potentially experience higher infection burdens with <em>Leucocytozoon</em> in contrast to Black-capped Chickadees. We found that elevation change (and associated ecology) drives the distributions of these parasite genera. For Boulder County chickadees, environmental factors play a more important role in structuring haemosporidian communities than host evolutionary differences. However, evolutionary differences are likely key to shaping the probability of infection, infection burden, and whether an infection remains detectable over time. We found that for recaptured birds, their infection status (i.e., presence or absence of detectable parasite infection) tends to remain consistent across capture periods. We sampled 234 chickadees between 2017–2021 across a ~1500-meter elevation gradient from low elevation (i.e., the city of Boulder) to comparatively high elevation (i.e., the CU Boulder Mountain Research Station). It is unknown whether long-term haemosporidian abundance trends have changed over time in our sampling region. However, we ask whether potentially disparate patterns of <em>Plasmodium</em> susceptibility and <em>Leucocytozoon</em> infection burden could be playing a role in the negative population trends of Mountain Chickadees.</p>
