    Population variation in germination strategies in an edaphic specialist

    Endemic species in biodiversity hotspots are often dependent on edaphic conditions and germination strategies that allow them to persist under climatically variable conditions. Torres-Martinez et al. tested whether geographic variation in historical precipitation patterns predicts patterns of dormancy and germination timing for populations of Lasthenia fremontii, a vernal pool annual endemic to the California Floristic […] More

    Maize root growth angles, nitrogen capture and environmental conditions

    Crops capable of improved nitrogen capture are in demand for the purposes of efficient global agricultural production. Dathe et al. employ functional-structural modelling to test the hypothesis that variation in the growth angles of maize roots is an important determinant of nitrogen uptake. They find that root growth angles are primary determinants of nitrogen acquisition […] More
