High MHC gene copy number maintains diversity despite homozygosity in a Critically Endangered single-island endemic bird, but no evidence of MHC-based mate choice
<p>Raw sequence data from two amplicon libraries of MHC class I exon 3 of Raso Lark <em>Alauda razae</em>, sequenced on an Illumina Miseq. The two different libraries (two different Illumina runs) are collected in separat tar archive (.tar). Within each of those are individual sequence reads as gzipped fastq files (.fastq.gz). Each sample has two files, one for read 1 (R1) and one for read 2 (R2), with file names structured as follows. Delimited by underscore (_) are:</p> <ol> <li>sample name as referred to in the data and paper (“RingNo” in the Supporting data table);</li> <li>formal ID (also referred to in data table, often corresponding to full ring number);</li> <li>Illumina sample number (i.e. based on the order that samples are listed in the sample sheet);</li> <li>Illumina lane number (static as L001, as Miseq instruments have a single lane on their flow cells);</li> <li>read number (R1 [forward] or R2 [reverse]);</li> <li>static identifier from Illumina (001).</li> </ol> <p>Thus, the file 83304_TJ83304_S163_L001_R2_001.fastq.gz is the reverse (read 2) MHC class I exon 3 sequence of individual 83304 (ring number TJ83304).</p>
Habitat-linked genetic variation supports microgeographic adaptive divergence in an island-endemic bird species
<p>We present evidence for and investigate potential mechanisms driving habitat-linked genetic divergence within a bird species endemic to a single 250 km<sup>2</sup> island. The island scrub-jay (<em>Aphelocoma insularis</em>) exhibits microgeographic divergence in bill morphology across pine-oak ecotones on Santa Cruz Island, California (USA) similar to adaptive differences described in mainland congeners over much larger geographic scales. To test whether individuals exhibit genetic differentiation related to habitat type and divergence in bill length, we genotyped over 3,000 single nucleotide polymorphisms (SNPs) in 123 adult island scrub-jay males from across Santa Cruz Island using restriction site-associated DNA sequencing (RADseq). Neutral landscape genomic analyses revealed that genome-wide genetic differentiation was primarily related to geographic distance and differences in habitat composition. We also found 168 putatively adaptive loci associated with habitat type using multivariate redundancy analysis (RDA) while controlling for spatial effects. Finally, two genome-wide association analyses revealed a polygenic basis to variation in bill length with multiple loci detected in or near genes known to affect bill morphology in other birds. Our findings support the hypothesis that divergent selection at microgeographic scales can cause adaptive divergence in the presence of ongoing gene flow.</p>

There are only two documented localities for it in the Central Range (3–4), and there is a large gap between the easternmost record of S. aureus (7) and the range of S. bakeri. The remaining Sericulus allospecies in New Guinea is Flame Bowerbird S. ardens of the southern watershed.
