Reproduction alternation in trees: testing the resource depletion hypothesis using experimental fruit removal in<i>Quercus ilex</i> Open
The keystones of resource budget models to explain mast seeding are that fruit production depletes tree stored resources, which become subsequently limiting to flower production the following year. These two hypotheses have, however, rarel…

Holm oak fecundity does not acclimate to a drier world Open
Summary Climate change might impact tree fecundity by altering the relative influences of meteorological and physiological drivers, and by modifying resource investment in reproduction. Using a 13‐yr monitoring of Quercus ilex reproduction…

Drivers of holm oak fecundity Open
Le changement climatique exerce une pression croissante sur les forêts du monde entier, et ses impacts potentiels sur la fécondité des arbres sont encore mal compris. De nombreuses espèces d’arbres forestiers se reproduisent suivant des pa…

Déterminisme environnemental de la fécondité du chêne vert Open
Climate change is placing increasing pressure on forests around the world, and its potential impacts on the reproductive capacity of individuals are yet poorly understood. Many forest tree species reproduce following so-called masting patt…

Resource manipulation through experimental defoliation has legacy effects on allocation to reproductive and vegetative organs in<i>Quercus ilex</i> Open
Background and Aims In plants, high costs of reproduction during some years can induce trade-offs in resource allocation with other functions such as growth, survival and resistance against herbivores or extreme abiotic conditions, but als…

Floral trait differentiation in<i>Anacamptis coriophora</i>: Phenotypic selection on scents, but not on colour Open
Current divergent selection may promote floral trait differentiation among conspecific populations in flowering plants. However, whether this applies to complex traits such as colour or scents has been little studied, even though these tra…

Divergent selection on flowering phenology but not on floral morphology between two closely related orchids Open
Closely related species often differ in traits that influence reproductive success, suggesting that divergent selection on such traits contribute to the maintenance of species boundaries. G ymnadenia conopsea ss. and Gymnadenia densiflora …

Flower phenology as a disruptor of the fruiting dynamics in temperate oak species Open
Summary Many perennial plants display masting, that is, fruiting with strong interannual variations, irregular and synchronized between trees within the population. Here, we tested the hypothesis that the early flower phenology in temperat…

Quelle interministérialité pour le Conseil National de l'Alimentation ? Open
Cette analyse s'inscrit dans un contexte de prise de poste recente de la secretaire interministerielle du CNA et du demarrage d'une nouvelle mandature (2016-2019). Ce projet doit permettre au commanditaire de mieux apprehender les enjeux d…
