Donald Price (Life Sciences) was part of a team including scientists from Harvard, Bishop Museum, Louisiana State University, UC Davis, and the University of Hawaii that recently published an article in Current Biology titled "Reproductive Capacity Evolves in Response to Ecology through Common Changes in Cell Number in Hawaiian Drosophila."  They investigated potential effects of ecology on the developmental processes underlying ovariole number evolution among Hawaiian Drosophila, a large...

Joy A. McKenna (Life Sciences) was selected by the Graduate College to receive the first place 2018-19 UNLV Outstanding Graduate Student Teaching Award, which is a highly selective and prestigious award recognizing a strong commitment to outstanding pedagogy and successful experiences thus far with undergraduate instruction at UNLV. McKenna received a $2,500 stipend in addition to being recognized by the UNLV Women's Council for this accomplishment. She is a Ph.D. candidate in the laboratory of...

Elizabeth Stacy and Donald Price (both Life Sciences), along with two former graduate students from the Stacy lab, have a paper in press, "Varieties of the Highly Dispersible and Hypervariable Tree, Metrosideros polymorpha, Differ in Response to Mechanical Stress and Light Across a Sharp Ecotone" in the American Journal of Botany. This study examines the drivers of isolation between sympatric populations of long-lived and highly-dispersible conspecific trees, which are poorly understood.  The...

Kelly Tseng, Cindy Kha, and Dylan Guerin (all Life Sciences) published a research article, "Using the Xenopus Developmental Eye Regrowth System to Distinguish the Role of Developmental Versus Regenerative Mechanisms," in the journal Frontiers in Physiology. This study addressed the role of developmental mechanisms in regenerating eye tissues after injury. The authors showed that regeneration of the retina recapitulates the developmental process. Furthermore, they identify a gene that is used by...

Elizabeth Stacy and Tomoko Sakishima (both Life Sciences) authored a paper in press for the Journal of Biogeography, "Phylogeography of the Highly Dispersible Landscape-dominant Woody Species Complex, Metrosideros, in Hawaii." They carried out a population genetic analysis of >1,500 adults of Hawaii's dominant tree from across the archipelago for insights into how diversification occurs within long-lived, highly dispersible and continuously distributed groups. They find, among other results...
May 1, 2019
Dylan Guerin (Life Sciences), was featured as the "Visitor of the Week" by Cold Spring Harbor Laboratories on Long Island, New York. A doctoral student in the research group of professor Kelly Tseng, Guerin was selected to attend the Cold Spring Harbor Laboratories' course on Cell & Developmental Biology of Xenopus and received a Howard Hughes Medical Institute scholarship. His research seeks to identify and understand the genes that promote eye regeneration.
April 25, 2019
Melissa Schofield and Muneeba Ahmed (both Life Sciences)  were recognized for their outstanding presentations at the 2019 AZ-NV American Society for Microbiology branch meeting. Schofield, a doctoral student in Boo Shan Tseng's lab, received the top prize for graduate student oral presentation. Ahmed, an undergraduate researcher in Brian Hedlund's lab, was recognized for an outstanding poster presentation
April 23, 2019
Boo Shan Tseng (Life Sciences) was awarded a Cystic Fibrosis Foundation pilot grant, entitled "Suppressors of mucA essentiality in Pseudomonas aeruginosa." She, with her team of undergraduate and graduate students, will use this two-year, $107,290 award to study why the gene mucA, is required for bacteria to survive. This bacterial gene is important in infection, as mutations of this gene is strongly correlated with death of cystic fibrosis patients chronically infected with this pathogen....

Elizabeth Stacy and Donald Price , along with doctorate candidate Tomoko Sakishima published "Multiple Colonizations, Hybridization and Uneven Diversification in Cyrtandra (Gesneriaceae) Lineages on Hawai'i Island" in the Journal of Biogeography.  This work used variation at nine single-copy nuclear genes in this species-rich plant genus to investigate the roles of colonization and hybridization in shaping community assemblages.  Results revealed rapid diversification (3.5 species/My) of one of...

Linda Lister (Music), Brian Hedlund (Life Sciences), and Zhaohuan Zhu (Physics and Astronomy) have been selected by the NSHE Board of Regents to receive this year's Regents’ Awards, which honor accomplishments that increase NSHE’s stature in five areas: teaching, academic advising, creative activities, research, and early-career (or “rising”) research. The board selected three faculty members whose work related specifically to research and creative activity. Lister received a Regents’ Creative...

Alexis Sauceda-Quintero, Yesenia Cuenca, and Kelly Tseng (all School of Life Sciences) are highlighted as "trailblazers" in videos on the Nevada STEM mentor network, sponsored by the NSHE system sponsored programs and EPSCoR office. This website showcases contributions to STEM research, education, and mentorship. Undergraduate students Cuenca and Sauceda-Quintero are research mentees of Tseng, an associate professor. Cuenca was a recipient of undergraduate research fellowships from the National...
March 8, 2019
Donald Price (Life Sciences) had a paper, "Hawaiian Picture‐winged Drosophila Exhibit Adaptive Population Divergence along a Narrow Climatic Gradient on Hawaii Island,"  published in Ecology and Evolution. The paper stems from work done in Price's laboratory with Jonathan Eldon, a previous graduate student now at Indiana University, and Renee Belinger,, a postdoctoral researcher in Hawaii. Anthropogenic influences on global processes and climatic conditions are increasingly affecting ecosystems...
