Soil aggregation and associated nutrient content along a distance-from-tree gradient in a low input cropping system. Comparing the effect for two tree species: Mangifera indica (mango, Anacardiaceae) vs. Faidherbia albida (faidherbia, Fabaceae)

Trees can play a major role in improving soil quality and thus have the potential to enhance sustainability of agroecosystems. Although this has been well established, knowledge on the effect of individual trees on aggregate stability and associated-nutrie ...

Integrating models across temporal and spatial scales to simulate landscape patterns and dynamics in mountain pasture-woodlands

Alexander Ludwig Johannes Peringer

Context Pasture-woodlands are semi-natural landscapes that result from the combined influences of climate, management, and intrinsic vegetation dynamics. These landscapes are sensitive to future changes in land use and climate, but our ability to predict t ...

Anthropogenic charcoal-rich soils of the XIX century reveal that biochar leads to enhanced fertility and fodder quality of alpine grasslands

Soil incorporation of charcoal (biochar) has been suggested as practice to sequester carbon, improve soil properties and crop yields but most studies have been done in the short term. Old anthropogenic charcoal-rich soils in the Alps enable to explore the ...

Importance Sampling Tree for Large-scale Empirical Expectation

François Fleuret, Olivier Canévet, Cijo Jose

We propose a tree-based procedure inspired by the Monte-Carlo Tree Search that dynamically modulates an importance-based sampling to prioritize computation, while getting unbiased estimates of weighted sums. We apply this generic method to learning on very ...

Herbaceous Angiosperms Are Not More Vulnerable to Drought-Induced Embolism Than Angiosperm Trees

Alexandre Buttler, Hervé Cochard, Constant Signarbieux

The water transport pipeline in herbs is assumed to be more vulnerable to drought than in trees due to the formation of frequent embolisms (gas bubbles), which could be removed by the occurrence of root pressure, especially in grasses. Here, we studied hyd ...

Subfossil peatland trees as proxies for Holocene palaeohydrology and palaeoclimate

Luca Bragazza

Due to the scarcity of reliable and highly resolved moisture proxies covering much of the Holocene, there has been increased interest in the study of living and subfossil peatland trees sensitive to gradual and extreme changes in hydrology, precipitation, ...

Multi-scale feedbacks between tree regeneration traits and herbivore behavior explain the structure of pasture-woodland mosaics

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

The pasture-woodlands of Central Europe are low-intensity grazing systems in which the structural richness of dynamic forest-grassland mosaics is causal for their high biodiversity. Distinct mosaic patterns in Picea abies- and Fagus sylvatica-dominated pas ...

A TASTY Alternative

Martin Odersky, Eugene Burmako, Dmytro Petrashko

This document proposes a new serialization format for typed syntax trees of Scala programs. It aims to be ● compact: All numbers and references are length encoded, trees are inlined by default but may be shared. ● lazy: Trees can be explored from the top, ...

A maximum-likelihood approach for building cell-type trees by lifting

Bernard Moret, Philipp Bucher, Yu Lin, Mingfu Shao, Nishanth Ulhas Nair, Paulina Grnarova, Laura Madeleine Hunter

Background: In cell differentiation, a less specialized cell differentiates into a more specialized one, even though all cells in one organism have (almost) the same genome. Epigenetic factors such as histone modifications are known to play a significant r ...

Homogenization of a multiscale viscoelastic model with nonlocal damping, application to the human lungs

Paul Isaac Denis Louis Marie Cazeaux

We are interested in the mathematical modeling of the deformation of the human lung tissue, called the lung parenchyma, during the respiration process. The parenchyma is a foam-like elastic material containing millions of air-filled alveoli connected by a ...
