Recent methodological advances have opened new perspectives for tropical
dendrochonological studies by facilitating the visualization, delimitation, and analyses of …

During the last two decades the tropical Amazon forests have been impacted by frequent
and severe droughts. However, little is known about the impacts of these extreme events on …

Background The distribution of trace elements in tree rings although poorly known may be
useful to better understand environmental changes, pollution trends, long-term droughts …

Background The increase in the frequency and intensity of droughts is pointed out as one of
the main factors altering biogeochemical cycles in the Amazon basin. An eco-nutritional …

The analysis of climate variability and development of reconstructions based on tree-ring
records in tropical forests have been increasing in recent decades. In the Amazon region …

To ensure unbiased tree-ring radiocarbon (14 C) results, traditional pretreatments carefully
isolate wood cellulose from extractives using organic solvents, among other chemicals. The …

Abstract The Seasonally Dry Tropical Forests (SDTF) present very high biodiversity and a
number of tree species that are adapted to prolonged periods of water stress. Considering …

Tropical dry forests (TDF) are highly important tropical forest ecosystems. Yet, these forests
are highly threatened, usually neglected and only poorly studied. Understanding the long …

Tree-ring width chronologies of cedro (Cedrela fissilis Vell.)(1875 to 2018), jatobá
(Hymenaea courbaril L.)(1840 to 2018) and roxinho Peltogyne paniculata Benth.)(1910 to …

Seasonally dry tropical forests are an important global climatic regulator, a main driver of the
global carbon sink dynamics and are predicted to suffer future reductions in their productivity …
