Endangered Pinto/Northern Abalone (Haliotis kamtschatkana) are Panmictic Across Their 3700 km Range Along the Pacific Coast of North America by J. L. Dimond, J. V. Bouma, F. Lafarga‐De la Cruz, K. J. Supernault, T. White, D. A. Witting

“…We employed reduced representation sequencing (RADseq) to generate single nucleotide polymorphism (SNP) data, assessing population connectivity and potential adaptive variation at 12 locations across the full range from Alaska to Mexico. Despite depleted populations, our analysis of over 6000 SNPs across nearly 300 individuals revealed that pinto abalone maintains a high genetic diversity with no evidence of a genetic bottleneck. …”

Potential plant extinctions with the loss of the Pleistocene mammoth steppe by Jérémy Courtin, Kathleen R. Stoof-Leichsenring, Simeon Lisovski, Ying Liu, Inger Greve Alsos, Boris K. Biskaborn, Bernhard Diekmann, Martin Melles, Bernd Wagner, Luidmila Pestryakova, James Russell, Yongsong Huang, Ulrike Herzschuh

“…Here, we introduce a method for detection of plant taxa loss at regional (extirpation) to potentially global scale (extinction) and their causes, as determined from ancient plant DNA metabarcoding in sediment cores (sedaDNA) from lakes in Siberia and Alaska over the past 28,000 years. Overall, potential plant extinctions track changes in temperature, in vegetation, and in megafauna extinctions at the Pleistocene-Holocene transition. …”

Genetic history of the Koryaks and Evens of the Magadan region based on Y chromosome polymorphism data by B. A. Malyarchuk, M. V. Derenko

“…The analysis of microsatellite loci for haplogroup Q-B143 in the Eskimos of Greenland, Canada and Alaska as well as in the indigenous peoples of Northeastern Siberia showed a decrease in genetic diversity from east to west, pointing to the direction of distribution of the Paleo-Eskimo genetic component in the circumpolar region of America and Asia. …”

Demographic disparities in access to COVID-19 clinical trial sites across the United States: a geospatial analysis by Raphael Cuomo, Tiana McMann, Qing Xu, Zhuoran Li, Joshua Yang, Julie Hsieh, Christine Lee, Milena Lolic, Richardae Araojo, Tim Mackey

“…Sites were more likely to be found in counties with higher proportions of Asian (p < 0.001) and American Indian or Alaska Native residents (p < 0.001). Areas with greater concentrations of Black or African American residents had significantly lower concentrations of observational (p < 0.001) and government-sponsored COVID-19 studies (p = 0.003) in national analysis and significantly fewer concentrations of study sites in both Los Angeles (p < 0.001) and New York (p = 0.007). …”

Measurement error in remotely sensed fractional snow cover datasets: implications for ecological research by Rowan Jacques-Hamilton, Mihai Valcu, Eunbi Kwon, Tom S L Versluijs, Bart Kempenaers

“…We established 38 quadrats (80 m × 50 m) across a study site of Arctic tundra near Utqiaġvik, Alaska. At each quadrat, we estimated fractional snow cover (FSC) and the timing of snow melt using data from moderate resolution imaging spectroradiometer (MODIS), visible infrared imaging radiometer suite (VIIRS), and Sentinel-2 satellites. …”
