Abstract:
... The forest tree family Aceraceae is widespread in the northern hemisphere and it has ecological and economic importance. However, the phylogenetic relationships and classifications within the family are still controversial due to transitional intraspecific morphological characteristics and introgression hybridization among species. In this study, we determined the evolutionary relationships and mo ...

Abstract:
... Over the last decades, spring leaf‐out of temperate and boreal trees has substantially advanced in response to global warming, affecting terrestrial biogeochemical fluxes and the Earth's climate system. However, it remains unclear whether leaf‐out will continue to advance with further warming because species’ effective chilling temperatures, as well as the amount of chilling time required to break ...

Abstract:
... Global change is expected to increase savanna woody encroachment as well as fire spreading into forest. Forest–savanna ecotones are the frontier of these processes and can thus either mitigate or enhance the effects of global change. However, the ecology of the forest–savanna ecotone is poorly understood. In this study, we determined whether a distinct ecotonal tree community existed between fores ...

To reverse this trend, the country has adopted a “zero deforestation” agricultural policy and committed to rehabilitating its forest cover through the planting of high-value tree species in cocoa landscapes using a participatory approach. However, little is known regarding the ...

Abstract:
... The forest tree height and aboveground biomass (AGB) are important indicators for monitoring changes and trends in forest carbon storage and terrestrial carbon fluxes. Accurate large-scale wall-to-wall mapping of the forest tree height and AGB remain challenging due to the limited data availability for extraction tree height and the data signal saturation problem in AGB estimation. In this study, ...

Abstract:
... In dioecious species, females usually have higher sex-related costs than males. Consequently, trade-offs involving survival, growth, and reproduction are expected to differ between sexes. Here, we investigate several aspects of sex-related costs to test whether they are higher for females than males of a widely distributed, locally abundant, dioecious tropical forest tree species. For this, every ...

Abstract:
... The application of fertiliser, to both replace nutrients lost during mining and facilitate rapid vegetation re-establishment, is viewed as a key step in the restoration of post-mining landscapes. However, few studies have examined the long-term effects of a single initial fertiliser application on tree growth in restored sites. We report on a large-scale, fully replicated study that investigated t ...

Abstract:
... Fixed carbon (C) is a central resource, whose dynamic allocation by the tree determines its ability to establish, grow and compete with other species. Traditionally, tree C allocation has been estimated by isotopic or mass balance approaches. Here we developed a setup of ¹³CO₂ pulse-labeling, with a flux-coupled, three-phase detection, allowing us to follow C quantitatively. We examined C allocati ...

Abstract:
... Cultivated pastures occupy 30% of the Brazilian Cerrado. Most pastures have low productivity, demanding intensification. Pasture intensification, as conventionally proposed, promises conservation by land sparing. However, it does not embrace silvopastoral systems, a type of intensification that enhances carbon balance and in situ biodiversity conservation. In the Cerrado, silvopastoral systems wou ...
