Responses of antinomic foliar traits to experimental climate forcing in beech and spruce saplings

Alexandre Buttler, Rodolphe Schlaepfer, Constant Signarbieux, María Paula Sanginés De Cárcer

Global warming is predicted to have a strong impact on mountain ecosystems. Subalpine sylvopastoral systems are very sensitive to climate change, which puts their future sustainability at stake. These ecosystems are mostly dominated by spruce and beech, an ...

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 ...

Sensitivity and resistance of soil fertility indicators to land-use changes: New concept and examples from conversion of Indonesian rainforest to plantations

Thomas Guillaume

Tropical forest conversion to agricultural land leads to a strong decrease of soil organic carbon (SOC) stocks. While the decrease of the soil C sequestration function is easy to measure, the impacts of SOC losses on soil fertility remain unclear. Especial ...

Earthworm communities in alluvial forests: Influence of altitude, vegetation stages and soil parameters

Claire Guenat, Géraldine Michèle Bullinger, Jean-Michel Gobat, Renée-Claire Le Bayon

In many terrestrial ecosystems, soil parameters usually regulate the distribution of earthworm communities.In alluvial ecosystems, few studies have investigated the impact of periodic floods and alluvium deposition on soil fauna. In this context, we assume ...

Wind sheltering of a lake by a tree canopy or bluff topography

Fernando Porté Agel, Corey Dean Markfort

[1] A model is developed to quantify the wind sheltering of a lake by a tree canopy or a bluff. The experiment-based model predicts the wind-sheltering coefficient a priori, without calibration, and is useful for one-dimensional (1-D) lake hydrodynamic and ...

Stratégies villageoises pour la gestion des paysages forestiers du Menabe Central, Madagascar

Clémence Dirac Ramohavelo

Introduction In order to reduce deforestation, the current attitude of conservation programmes and forest politics does no longer ban the local populations from the forests, because such measures present negative consequences for the communities. Today's t ...

A game-theoretical model of deforestation in human-environment relationships

Antonio Rodrigues

We studied a two-person game regarding deforestation in human–environment relationships. Each landowner manages a single land parcel where the state of land-use is forested, agricultural, or abandoned. The landowner has two strategies available: forest con ...

GIS modelling of forest wood residues potential for energy use based on forest inventory data: Methodological approach and case study application

Edgard Gnansounou, Luis Alberto Panichelli

This paper presents an approach to perform geo-referenced estimations of forest wood residues availability for energy use based on forest inventory data integration into a GIS. Three different estimation methods are described. The first one evaluates bioma ...

Semi-automatic Use of High Resolution Images and Digital Elevation Models for Counting and Identification of Forest Trees

Claudio Magalhaes Carneiro

This paper presents a semi-automatic and systematic computational approach intending to count and localize different species of trees in zones of dense forest. Comparative analysis of the application of multi-spectral high resolution images and aerial LIDA ...

Short-term effects of cattle browsing on tree sapling growth in mountain wooded pastures

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two siz ...
