"Hybridization among three juniper taxa along the Sierra-Great Basin
Ecotone"

Talk Description


Junipers are a foundational woody plant across many arid and semi-arid
landscapes of western North America. Pinyon-juniper woodlands cover
millions of acres across the western United States, providing vital food
and habitat resources for many arthropod, bird, and mammal species. Along
the Sierra-Great Basin Ecotone, three juniper taxa come into contact and
hybridize, forming a broad hybrid zone along the border of California and
Nevada. To determine the ancestry of the hybrids, I generated a large
population genetic data set (9,125 SNPs; 25 populations; 326 individuals)
that spanned the hybrid zone and the geographic ranges of the three taxa.
For these same individuals, my collaborators and I characterized
phytochemical variation (163 terpenoid molecules) to understand how leaf
chemistry varies across pure individuals and hybrids. I compare patterns of
genetic, phytochemical, and environmental variation across the landscape to
understand the evolutionary consequences and ecological drivers of
hybridization in this system.

*Bio*


Dr. Kathryn Uckele is a postdoctoral scholar in the Department of Ecology
and Evolutionary Biology at the University of California, Santa Cruz, where
she studies the evolution and diversification of the
tropical spiral gingers (*Costus*). In 2022, she received her PhD in
Ecology, Evolution, and Conservation Biology from the University of Nevada,
Reno, where much of her research focused on understanding the genomic and
phenotypic consequences of hybridization among three juniper taxa.
