Multispectral canopy reflectance improves spatial distribution models of Amazonian understory species
Species distribution models are required for the research and management of biodiversity in the hyperdiverse tropical forests, but reliable and ecologically relevant digital environmental data layers are not always available. ...
Using digital soil maps to infer edaphic affinities of plant species in Amazonia: Problems and prospects
Amazonia combines semi-continental size with difficult access, so both current ranges of species and their ability to cope with environmental change have to be inferred from sparse field data. Although efficient techniques ...
The role of topographic-derived hydrological variables in explaining plant species distributions in Amazonia
In Amazonian terra-firme non inundated forests, local floristic composition and species occurrence are explained by water availability as determined by topographic conditions. Topographic complexity can render these ...
Dating flowering cycles of Amazonian bamboo-dominated forests by supervised Landsat time series segmentation
Bamboo-dominated forests are unusual and interesting because their structure and biomass fluctuate in decades-long cycles corresponding to the flowering and mortality rhythm of the bamboo. In southwestern Amazonia, these ...
Climate Change in the Baltic Sea Region: A Summary
<p>Based on the Baltic Earth Assessment Reports of this thematic issue in Earth System Dynamics and recent peer-reviewed literature, current knowledge about the effects of global warming on past and future changes in climate ...
A comprehensive spatial model for historical travel effort - a case study in Finland
Contributing to multidisciplinary studies of human population history, this paper presents an analysis chain to comprehensively model the historical travel environment in Finland, based on a study of spatial patterns of ...

Phytolith assemblages in the leaves of Guadua bamboo in Amazonia
<p>Abstract: We studied phytoliths (plant stones) from
228 leaf samples of Guadua weberbaueri and Guadua
sarcocarpa bamboos from eleven collection locations
in Southern Peruvian Amazonia and in the state of Acre
in ...
Geologically recent rearrangements in central Amazonian river network and their importance for the riverine barrier hypothesis
<p>The riverine barrier hypothesis is a central concept in Amazonian
biogeography. It states that large rivers limit species distributions
and trigger vicariant speciation. Although the hypothesis has
explanatory ...
Best practices in justifying calibrations for dating language families
<p>The use of computational methods to assign absolute datings to language divergence is receiving
renewed interest, as modern approaches based on Bayesian statistics offer alternatives to the discredited techniques of ...
