“…Water availability is erratic and, in general, substrates are mineral rich (Pennington et al 2009). The vegetation is dominated by trees, most of which are deciduous during the dry season Prado and Gibbs 1993;Santos et al 2007;Caetano et al 2008;Santos et al 2012;Calvo-Rodriguez et al 2017). Myracrodruon urundeuva is widely used in popular therapeutic treatments (Monteiro et al 2012), due to the high concentration of secondary metabolites present in vegetative parts (Viana et al 1995;Queiroz et al 2002).…”

Myracrodruon urundeuva (Baroeira^) is a dioecious tree of the seasonally dry tropical forest (SDTF) of Brazil and source of a unique unifloral honey. To discriminate this honey by its pollen spectra, we compared melissopalynological analysis of reference honey samples with those of other samples collected in the SDTF belt. Reference honeys had on average 99% of aroeira pollen, while the other honey samples averaged 84% of this pollen. We used the receiver operating characteristic (ROC) curve, applied here for the first time in honey analysis, for determining the cut-off value of at least 93% of Myracrodruon pollen in a sample for classifying unifloral aroeira honey. The over-representation of aroeira pollen in this honey reflects that honeybees visited ten times as many staminate flowers as pistillate flowers. We conclude that unifloral aroeira honey has uniform pollen spectra, as a byproduct of the preference of honeybees for staminate flowers.Myracrodruon urundeuva / receivers operating characteristic (ROC) curve / melissopalynology / Apis mellifera Corresponding author: C.

“…The annual tree mortality rates reported for Neotropical dry and semi -deciduous forests ranges between 1.9% and 4.1% (for DBH > 10 cm) (Felfili, 1995;Uslar et al, 2011;Torres et al, 2012) and between 1.3% and 4.9% (for DBH > 5 cm) (Aquino et al, 2007;Carbajal and Calvo, 2013;Aguirre, 2016;Calvo-Rodriguez et al, 2017). These values are considerably higher than the mortality rate we report here (0.72%).…”

Studies about the complex processes of forest dynamics in pre-montane and montane forests (between 600 - 3000 m altitude) are rare. This study contributes to our knowledge on changes in the floristic composition and population dynamics of woody species in a sub-xerophilous formation immersed in the humid pre-montane and montane forests of Peru. In 2015 we re-measured trees with diameter at breast height equal or greater than10cm in a permanent plot established in 2009. We recorded 31 species of 25 families, with a Fisher's Alpha diversity index of 7.5. The most abundant and dominant species (including Heteropterys intermedia, Physocalymma scaberrimum, Sapium glandulosum, Tachigali peruviana and Machaerium hirtum) represented 66.25% of all species in 2009 and 66.36% in 2015. The prevalence of these species and others ensures the maintenance of a characteristic seasonally dry forest formation within the census period (6.25 years). The dynamics of this forest, with a high rate of recruitment (3.82%) and a low rate of mortality (0.72%), show favorable conditions for the maintenance of this forest fragment.
