Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

Soil and Forest Degradation Driven by Cattle Grazing and Selective Logging in Sub‐Antarctic Nothofagus Ecosystems of Patagonia

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil and forest degradation driven by chronic land‐use pressures is an increasingly widespread process in forested landscapes worldwide, yet its empirical characterization remains limited, particularly in temperate and sub‐Antarctic ecosystems.

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam

open access: yesNordic Journal of Botany, EarlyView.
A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

open access: yesNordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

An assessment of the use of airborne LiDAR for estimating growth of Sitka spruce (Picea sitchensis) plantation forestry at Kielder Forest, UK [PDF]

open access: yes, 2007
A growing need exists for the collection of accurate and up-to-date information on forest growth rates for management purposes. Recent studies indicate that airborne laser scanning (ALS) offers a quicker and more cost-effective approach than the ...

Data from: Canopy height explains species richness in the largest clade of Neotropical lianas

open access: yes, 2019
Aim: Tall and structurally complex forests can provide ample habitat and niche space for climbing plants, supporting high liana species richness. We test to what extent canopy height (as proxy of 3D habitat structure), climate and soil interact to ...

Update on Ouratea cidiana Sastre (Ochnaceae), a microendemic species from the Amazon: enlightening the identity and conservation status

open access: yesNordic Journal of Botany, EarlyView.
Ouratea cidiana (Ochnaceae) is a microendemic shrub species from the Brazilian Amazonia, occurring along the banks of the Trombetas River and restricted to the Cachoeira Porteira region, in western Pará State. Since the original collection nearly forty years ago, no additional records have been made, which is concerning given the continuous decline in ...

Canscora agni (Gentianaceae), a new species from the fire‐prone Indian savannas

open access: yesNordic Journal of Botany, EarlyView.
We describe Canscora agni from the Indian savannas as a distinct species which differs from its allied species Canscora alata in having fewer and shorter leaves, pedicel‐wings unequal across the length, bracts with glandular hair on the margins, calyx‐wings being four, wider, up to 2.3 mm, with distinct reticulate venation and having ovary length up to
