An overview of existing and promising technologies for national forest monitoring
The main goal of national forest programs is to lead and steer forest policy development and implementation processes in an inter-sectoral way (FAO 2006). National forest monitoring systems contribute to forest programs through monitoring forest changes and

Overcoming obstacles to sharing data on tree allometric equations
Advances in ecology face the complexity of ecosystems with dynamics longer than a single scientist’s career. In forestry and REDD+ practice, in particular, our ability to understand forest ecosystem dynamics and to manage them for mitigation and

“50 years Annals of Forest Science”: Can mosses serve as model organisms for forest research?
Based on their impact on many ecosystems, we review the relevance of mosses in research regarding stress tolerance, metabolism, and cell biology. We introduce the potential use of mosses as complementary model systems in molecular forest research,

C depletion and tree dieback in young peach trees: a possible consequence of N shortage?
By Erwin Dreyer On 13 March 2015 In Non classé
Bud burst disruption, carbon depletion and tree dieback in spring were experimentally linked to N shortage the previous autumn. Dieback occurred despite tree N concentrations were compatible with plant survival: their N stores being blocked in the

Phosphorus nutrition of beech (Fagus sylvatica L.) is decreasing in Europe
Foliar phosphorus concentrations have decreased in Europe during the last 20 years. High atmospheric nitrogen deposition and climate change might be responsible for this trend. Continued decrease in foliar P concentrations might lead to reduced growth and vitality

A novel method to correct for wood MOE ultrasonics and NIRS measurements on increment cores in Liquidambar styraciflua L
Ultrasounds overestimate the MOE value. This paper analyses the causes of this difference and opens the perspective for a novel method allowing the calculation of the correct MOE from ultrasounds or NIRS measurements on cores. Standardized methods

The effects of thinning intensity and tree size on the growth response to annual climate in Cedrus atlantica: a linear mixed modeling approach
With a retrospective growth analysis over 20 years, we showed that silviculture (in particular thinning) of Cedrus atlantica (Manetti) could to some extent mitigate the effects of drought episodes. Severe reductions of density resulted in faster recovery of

“50 years Annals of Forest Science”: Certainties and uncertainties about the life cycle of the Périgord black truffle (Tuber melanosporum Vittad.)
Several aspects of the life cycle of the Périgord black truffle have been elucidated only recently, while others remain either controversial or unstudied. In this paper, we present a revised life cycle of this fungus and highlight

Life after disturbance: changes in the spatial genetic structure of Jacaranda copaia after logging in French Guiana
Forest disturbance affects the within-population distribution of genetic diversity, but not its overall levels, in a tropical pioneer tree species. In particular, clumps of related saplings with impoverished diversity are found in canopy gaps but not under

Monitoring ectomycorrhizal fungi at large scales for science, forest management, fungal conservation and environmental policy
The ICP Forests network can be a platform for large-scale mycorrhizal studies. Mapping and monitoring of mycorrhizas have untapped potential to inform science, management, conservation and policy regarding distributions, diversity hotspots, dominance and rarity, and indicators of
