Polyculture affects biomass production of component species but not total standing biomass and soil carbon stocks in a temperate forest plantation

Over-yielding of stand biomass did not occur in a tree polyculture comprised of Betula pendula, Alnus glutinosa and Fagus sylvatica selected for contrasting traits. This was due to antagonistic interactions between the component species. Fine root dynamics

Fire activity and burned forest lands decreased during the last three decades in Spain

Fire activity has decreased in the last decades in Spain as a whole and in most provinces. However, fire risk factors have increased. Wildfires are burning preferentially treeless areas. Flammable pine areas burn less, while the less

Phenology of wood formation in larch (Larix decidua Mill.) trees growing along a 1000-m elevation gradient in the French Southern Alps

Spring temperature increase is the main driver of larch tree wood formation onset along a 1000-m elevation gradient in the Southern Alps, while its cessation is more probably controlled by water stress at the lowest elevation and

Stem cycle analyses help decipher the nonlinear response of trees to concurrent warming and drought

High-resolution analysis of stem radius variation can quantify the impact of warming and drought on stem water balance and stem growth in black spruce [ Picea mariana (Mill.) B.S.P.)]. Drought affected plant water status and stem growth.

Scaling-up individual-level allometric equations to predict stand-level fuel loading in Mediterranean shrublands

Allometric biomass equations developed for individual shrubs can be applied to estimate shrubland fuels from measurements of cover and average height by species. Context Shrubs are a major component of surface fuels in many fire-prone ecosystems. Shrub

Guidelines for reviewers: How to review a data paper?

Data papers aim at describing a dataset made available to a larger community. Data papers are a scientific valuable production and should provide all required information for a large use of the data. The data paper should

Long-term loblolly pine land use reduces methane and net greenhouse gas emissions in a subtropical Cambisol, despite increasing nitrous oxide

In loblolly pine land use of 17–32 years following forest clearing, CH4 consumption and N2O emission diminished by 17 years, due to high soil moisture (~ 80% WFPS, N2O into N2 ), but increased by 32 years, where

Climate has a larger effect than stand basal area on wood density in Pinus ponderosa var. scopulorum in the southwestern USA

Stand basal area of ponderosa pine ( Pinus ponderosa var. scopulorum Engelm.) in the US Southwest has little effect on the density of the wood produced, but climatic fluctuations have a strong effect. Wood density increases during

Seasonal adjustment of primary and secondary growth in maritime pine under simulated climatic changes

Reducing irrigation by up to 75% in spring decreased primary and secondary growth in Pinus pinaster Aiton saplings, whereas an extra irrigation in September prompted secondary growth, confirming the high plasticity of xylogenesis in this species. Context

The utility of terrestrial photogrammetry for assessment of tree volume and taper in boreal mixedwood forests

This study showed that digital terrestrial photogrammetry is able to produce accurate estimates of stem volume and diameter across a range of species and tree sizes that showed strong correspondence when compared with traditional inventory techniques. This
