Inter- / inside-tree variations of reference wood characteristics of high value-added Central African timber species [PDF]

open access: yes, 2012
The Central African wood sector is characterised by a steady but sometime short-lived commercialisation of new timber species on the local market as well as for regional or international trading.

Solar Irradiance Variability and Climate

open access: yes, 2013
The brightness of the Sun varies on all time scales on which it has been observed, and there is increasing evidence that it has an influence on climate. The amplitudes of such variations depend on the wavelength and possibly on the time scale.

Does the altitude affect the stability of montane forests? A study in the Kahuzi-Biega National Park (Democratic Republic of the Congo) [PDF]

open access: yes, 2017
To understand the functioning of montane forests, this study was conducted in the highlands of the Kahuzi-Biega National Park in the Democratic Republicof the Congo.

Thermal Plasticity is Regulated by a Key MicroRNA During Range Expansion of an Invasive Fruit Fly

open access: yesAdvanced Science, EarlyView.
Populations at the invasion front of Bactrocera dorsalis adapt through reduced phenotypic and gene expression plasticity, a phenomenon likely to be driven by genetic assimilation. We identify a key miRNA‐mediated regulatory axis, in which miR‐276b post‐transcriptionally represses thw, a conserved chitin‐binding gene critical to the cold‐tolerance ...

Microbial growths and checking on acrylic painted tropical woods and their static bending after three years of natural weathering

open access: yesJournal of Materials Research and Technology, 2019
Wood products exposed outdoor could be weathered, especially in the tropical region with high in sun light, temperature, rain intensity, and relative humidity.

Stable Isotope Ratio Analysis for the Comparison of Timber From Two Forest Concessions in Gabon

open access: yesFrontiers in Forests and Global Change, 2022
Consumers are becoming increasingly aware of the environmental impacts caused by deforestation and illegal logging and there is an increasing demand for supply chain transparency and traceability of wood products.

Characterization of the fire behaviour of tropical wood species for use in the construction industry [PDF]

open access: yes, 2016
It is widely acknowledged that wood is a combustible and flammable material. However, not all woods have the same fire behaviour; this can change significantly depending on the type and species of wood.

Coupled Above‐ and Belowground Ecosystem Stability Worldwide

open access: yesAdvanced Science, EarlyView.
Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

Tropic Responses of Fungi to Wood Volatiles [PDF]

open access: yesMicrobiology, 1983
SUMMARY: Sapwood blocks of lime (Tilia vulgaris) and pine (Pinus sylvestris) placed to one side of growing colonies of several wood decay fungi markedly influenced their hyphal extension patterns, particularly by causing positive or negative tropic responses.

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

open access: yesAdvanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...
