Journals dedicated to the polar sciences have been outliers. Within both history of science and media, they stand out in several ways, including their comparatively late establishment peer-review. It was not until second half 20th century, that journals began carry predominantly peer-reviewed original research rather than synopses published elsewhere. This Perspective piece uses 40th anniversar...

Black cottonwood Populus balsamifera L. subsp. trichocarpa (Brayshaw) dominated riparian forests are important habitats for organisms in both terrestrial and aquatic ecosystems in the Pacific Northwest. Using a chronosequence approach and fixed area plots, successional processes were quantified in 28 stands along 145 km of the Willamette River in Western Oregon. Cluster analysis yielded five su...

Incorporation of forest slash during stand establishment is proposed as ameans of increasing soil carbon and nutrient stocks. If effective, the increased soil carbon and nutrient status may result in increased aboveground tree growth. Eight years after study installation, the impact of forest slash incorporation into the soil on soil carbon and nutrient stocks, foliar nutrients and loblolly pin...

115 Eastern white pine (Pinus strobus L.) was often associated with oaks (Quercus spp.) on upland sites in presettlement forests of the upper Great Lakes region, but widespread logging and subsequent fires in the late 1800s converted these upland sites to fire-tolerant oak forests. Although white pine regeneration is occurring in these second-growth oak forests, white pine regeneration patterns...

Abstract Wheat ( Triticum aestivum L.) production in Texas depends heavily on conventional tillage (CT) and a long summer fallow period, which contributes to soil degradation. This study compared the impact of reducing intensity (CT, no‐tillage, strip‐tillage) combined with cropping CT–summer wheat establishment, grain production, herbage mass from 2016 2020 three ecoregions (Coastal Plains, So...

During intrinsically asymmetric division, the spindle is oriented onto a polarized axis specified by a group of conserved PAR proteins. Extrinsic geometric asymmetry generated by cell shape also affects spindle orientation in some systems, but how intrinsic and extrinsic mechanisms coexist without interfering with each other is unknown. In some asymmetrically dividing cells of the wild-type Cae...
