Woody plant communities of isolated Afromontane cloud forests in Taita Hills, Kenya [PDF]

, 2010
In the Taita Hills in southern Kenya, remnants of the original Afromontane forest vegetation are restricted to isolated mountain peaks. To assess the level of degradation and the need for forest restoration, we examined how forest plant communities and ...

Restoring Overlogged Tropical Forests

, 2006
Overlogged forests are degraded but nevertheless important. They may continue to be a source of timber and supply an important amount of forest products, particularly for local people whose livelihoods depend on their extraction. One aspect of restoration would be to prevent adding more overlogged areas by implementing sound logging, silvicultural, and

A new geodatabase of fuel treatments across federal lands in the USA

Scientific Data
Catastrophic wildfires threaten landscapes across the United States, and fuel treatments are key to mitigating this risk. Yet, information regarding when, where, and what types of treatments have occurred is scattered across multiple systems of record ...

Tight relationships between leaf and topsoil stoichiometries after 42 years of forest conversion from old-growth forests to Chinese fir plantations

Frontiers in Forests and Global Change, 2023
Soil C:N:P stoichiometry can regulate plant survival and reflect soil fertility and nutrient utilization. Despite the widespread conversion of old-growth forests to plantations or secondary forests, there is little knowledge about how these conversions ...

Predicting Chronicity in Children and Adolescents With Newly Diagnosed Immune Thrombocytopenia at the Timepoint of Diagnosis Using Machine Learning‐Based Approaches

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Objectives To identify predictors of chronic ITP (cITP) and to develop a model based on several machine learning (ML) methods to estimate the individual risk of chronicity at the timepoint of diagnosis. Methods We analyzed a longitudinal cohort of 944 children enrolled in the Intercontinental Cooperative immune thrombocytopenia (ITP) Study ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Decadal stability of radiocesium inventories and soil to tree transfer in forests affected by the Fukushima nuclear accident

Scientific Reports
Understanding the long-term dynamics of radiocesium (137Cs) in forests contaminated by the Fukushima nuclear accident requires determining when these dynamics reach a quasi-equilibrium state, in which the flux of 137Cs between soil and trees becomes ...

Massive and effective acorn dispersal into agroforestry systems by an overlooked vector, the Eurasian magpie (Pica pica)

Ecosphere, 2019
Oak regeneration and the expansion of forested sites in Eurasia rely on acorn dispersal by animals, especially the Eurasian jay (Garrulus glandarius). However, in open agroforestry systems where jays are absent, such as old fields far from acorn sources,
