Tracking climate vulnerability across spatial distribution and functional traits in Magnolia gentryi from the Peruvian tropical montane cloud forest
<p>Understanding the responses of tree species' functional traits to climate variability is essential for predicting the future of Tropical Montane Cloud Forest (TMCF) tree species through acclimation, especially in Andean montane environments where fog pockets act as moisture traps. We studied the distribution of <em>Magnolia gentryi</em> to measure its spatial arrangement and identify local hotspots, while also evaluating the extent to which climate-related factors are associated with its distribution. Finally, we analyzed variations in 13 functional traits of <em>M. gentryi</em> and the climate links to infer the shaping plant acclimate capacity. Our results show that Andean TMCF climatic factors constrain <em>M. gentryi</em> spatial distribution with significant patches or gaps, associated with high precipitation rates and mean minimum temperature. The functional traits of <em>M. gentryi</em> are constrained by Andean TMCF climatic factors, resulting in reduced within-species acclimation in functional traits associated with a hydric deficit. The association between functional traits and climate oscillation is crucial for understanding the growth conditions of relict-endemic species and is essential for conservation efforts. Changes in forest trait diversity and species composition occur because of fluctuations in hydraulic safety–efficiency gradients.</p>

Data from: Is tropical montane forest heterogeneity promoted by a resource-driven feedback cycle? Evidence from nutrient relations, herbivory and litter decomposition along a topographical gradient
1. Ridges of tropical mountains often differ strikingly from neighbouring ravines in terms of forest structure, productivity, and species composition. This heterogeneity is poorly understood despite its critical role in biodiversity maintenance, carbon and nutrient budgets. 2. We examined measures of tree biomass and productivity, foliage and litter quality (nutrient concentrations, specific leaf mass, phenolics), herbivory and leaf litter decomposition in each six plots laid out in upper and lower slope position in a tropical montane moist forest in southeastern Ecuador. 3. Productivity, quality of foliage and litter and herbivory were significantly lower in upper slope position and closely correlated with soil nutrient concentrations and accumulated humus. The decomposition of upper slope leaf litter (decomposition rate k) was substantially lower than in litter from lower slope forest, whereas the site of decomposition (slope position) only had a marginal effect on the decomposition rate. 4. Our results suggest that the differences in stand structure, productivity, foliar quality, herbivory and decomposition between slope positions are ultimately due to stronger nutrient limitations in upper slope forest. We propose a general conceptual model that explains origin and maintenance of contrasting forest types along topographical gradients through down-slope fluxes of nutrients and water, and a nutrient-driven positive feedback cycle.
