Superimposed to these environ- mental (‘external hypothesis’) and intrinsic (‘endogenous hypothesis’) explana- tions, there may be phylogenetic constraints contributing to shape phenology. The phenology of tree and shrub species with fleshy fruits in a Dry Chaco forest in Argentina was studied addressing these hypotheses and following two approaches, with the species average values taken as independent data points, and removing phylogenetic effects. The hypotheses addressed are largely complementary to one another. Strong environmental restrictions conditioned general flowering patterns with species ´ endogenous characteristics acting secondarily. Phylogenetic patterns were also masked by climatic variables. When considering fruiting phenology, however, phylogeny, representing a set of species ´ shared traits, predominated over environmental restrictions.10aArgentina10adispersal guild10aDry Chaco forest10aflowering and fruiting patterns10aphenology10aphylogeny1 aMarco, D.E.1 aPáez, S.A.  uhttps://insectafgseag.myspecies.info/fr/node/384
