Microclimate and seed bank under <i>Pithecellobium keyense</i> (Fabaceae) in a coastal scrubland

Abstract Microclimatic conditions affect seeds' survival, dormancy, and germination, which are determinants in vegetation succession recovery. The semiarid coastal scrublands of Yucatan, Mexico very important because the environmental services they provide thus, studies needed disturbed sites relation to seed viability microclimate. In this study, we characterized microclimate bank under Pithecellobium keyense s hrubs, during rainy dry seasons. We collected soil samples measured microenvironmental variables adult P. at three different positions canopy every studied individual (“open” or completely sunny, “half‐shaded,” placed border canopy, “fully shaded” next stem shrub). Photosynthetic photon flux density (PPFD), minimum night‐time temperature, maximum daytime temperature behaved differently among both During season, was no microenvironments, while dry, highest found fully shaded lowest open position. had an effect on probability Chuburná; stronger season.
