Cultivated strawberry (Fragaria × ananassa) is one of our youngest domesticates, originating in early eighteenth-century Europe from spontaneous hybrids between wild allo-octoploid species (F. chiloensis and F. virginiana). The improvement of horticultural traits by 300 years of breeding has enabled the global expansion of strawberry production. Here, we describe the genomic history of strawberry domestication from the earliest hybrids to modern cultivars. We observed a significant increase in heterozygosity among interspecific hybrids and a decrease...

Scaling up experimental stress responses of grass invasion to predictions of continental-level range suitability

Bo Zhang, Yingdan Yuan, Lele Shu, Edwin Grosholz, Yuxi Guo, James Cuda, Jinchi Zhang, Lu Zhai & Jiangxiao Qiu
Understanding how the biological invasion is driven by environmental factors will improve model prediction and advance early detection, especially in the context of accelerating anthropogenic ecological changes. Although a large body of studies has examined how favorable environments promote biological invasions, a more comprehensive and mechanistic understanding of invasive species response to unfavorable/stressful conditions is still developing. Grass invasion has been problematic across the globe; in particular, C4 grass invaders, with high drought tolerance, adaptations...

Data from: Measuring behavior patterns and evaluating time sampling methodology to characterize brush use in weaned beef cattle

Kelsey Horvath, Rachel Toaff-Rosenstein, Cassandra Tucker & Emily Miller-Cushon
With growing interest in provision of brushes to cattle, and implications of brush use for behavioral development and welfare, there is a need to validate methodology for quantifying grooming behavior. Our objectives were to characterize patterns of brush use, including bouts, diurnal activity, and individual variability over 24-h periods and to validate time sampling methodologies to characterize these traits, including instantaneous recording at various time intervals and continuous recording for subsets of the day. Data...
