Such factors must be carefully evaluated and contextualized at both the intraspecific and interspecific levels when assessing the conservation status of imperiled species. Here, we studied the population genomics of a perching songbird, the California towhee (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Melozone crissalis<\/jats:italic>\n                    <\/jats:styled-content>\n                    ), by generating a high\u2010quality annotated reference genome assembly (N50\u2009=\u200922\u2009Mb among 627 contigs, max contig size 89.1\u2009Mb) and conducting whole\u2010genome resequencing on\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200981 individual birds sampled from multiple geographic sites across much of the species' range. California towhee sampled from Inyo County and from Southern Oregon, on the periphery of their geographic range, showed reduced heterozygosity and elevated inbreeding compared (a) to other sampled California towhee populations and (b) to related Threatened songbirds. Contemporary effective population sizes (\n                    <jats:italic>N<\/jats:italic>\n                    <jats:sub>\n                      <jats:italic>e<\/jats:italic>\n                    <\/jats:sub>\n                    ) were low for these two peripheral populations, and ancestry patterns of the federally protected Inyo population reveal the remarkably clear genomic signature of a documented, human\u2010induced demographic bottleneck.

Both peripheral populations show evidence indicative of local adaptation, as gauged by landscape genetic approaches. Our data highlight the tension that exists between the idealistic goal of conserving all the diversity in a gene pool (e.g., isolated peripheral populations that may contain locally adapted variants) versus the less desirable but more practical goal of focusing expensive conservation efforts on the core gene pool.\n                  <\/jats:p>","DOI":"10.1111\/eva.70313","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T05:49:41Z","timestamp":1787204981000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Natural and Anthropogenic Drivers of Genomic Diversity in the California Towhee: Conservation Implications for Peripheral Populations"],"prefix":"10.1111","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6745-9460","authenticated-orcid":false,"given":"Andrew N.","family":"Black","sequence":"first","affiliation":[{"name":"Department of Forestry &amp; Natural Resources Purdue University  West Lafayette Indiana USA"},{"name":"Western Association of Fish and Wildlife Agencies  Boise Idaho USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2840-8425","authenticated-orcid":false,"given":"Jong Yoon","family":"Jeon","sequence":"additional","affiliation":[{"name":"Department of Forestry &amp; Natural Resources Purdue University  West Lafayette Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0089-8063","authenticated-orcid":false,"given":"Chris","family":"McCreedy","sequence":"additional","affiliation":[{"name":"Point Blue Conservation Science  Petaluma California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Safia","family":"Janjua","sequence":"additional","affiliation":[{"name":"Department of Forestry &amp; Natural Resources Purdue University  West Lafayette Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6769-7848","authenticated-orcid":false,"given":"Erangi J.","family":"Heenkenda","sequence":"additional","affiliation":[{"name":"Department of Forestry &amp; Natural Resources Purdue University  West Lafayette Indiana USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6446-5718","authenticated-orcid":false,"given":"Samarth","family":"Mathur","sequence":"additional","affiliation":[{"name":"Department of Evolution, Ecology and Organismal Biology The Ohio State University  Columbus Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5232-001X","authenticated-orcid":false,"given":"Elise","family":"Ferree","sequence":"additional","affiliation":[{"name":"Department of Natural Sciences Scripps and Pitzer Colleges  Claremont California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy L.","family":"Fesnock","sequence":"additional","affiliation":[{"name":"Cosumnes River Preserve U.S. Bureau of Land Management  Galt California USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6320-1550","authenticated-orcid":false,"given":"Alvaro","family":"Hernandez","sequence":"additional","affiliation":[{"name":"Roy J.
