    Life on the edge—a changing genetic landscape within an iconic American pika metapopulation over the last half century by Kelly B. Klingler, Lyle B. Nichols, Evon R. Hekkala, Joseph A. E. Stewart, Mary M. Peacock

    Published 2023-09-01
    “…Genetic data extracted from both contemporary samples and archived natural history collections allowed us to track population and patch-level genetic diversity for Bodie pikas across three distinct sampling points during the last half- century (1948–1949, 1988–1991, 2013–2015). Reductions in within-population allelic diversity and expected heterozygosity were observed across the full time period. …”
