Circadian oscillation of gibberellin signaling in Arabidopsis
(National Academy of Sciences, 2011-05)Circadian clocks are endogenous timekeeping mechanisms that allow organisms to anticipate rhythmic, daily environmental changes. Temporal coordination of transcription results in a set of gene expression patterns with ... -
Classical biological control of an invasive forest pest : a world perspective of the management of Sirex noctilio using the parasitoid Ibalia leucospoides (Hymenoptera: Ibaliidae)
(2015-02)Classical biological control is a key method for managing populations of pests in long-lived crops such as plantation forestry. The execution of biological control programmes in general, as the evaluation of potential ... -
Climate warming differently affects Larix decidua ring formation at each end of a French Alps elevational gradient
(Springer, 2020-06)Key message The ongoing global warming tends to reduce Larix decidua radial growth and ring wood density at the bottom of an elevational gradient in the French Alps, while it has a less marked effect at the top. Context: ... -
