Precipitation is an important factor influencing the date of foliar senescence, which in turn affects carbon uptake of terrestrial ecosystems. However, the temporal patterns of precipitation frequency and its impact on foliar senescence date remain largely unknown. Using both long-term carbon flux data and satellite observations across the Northern...
Cola nitida is a key multipurpose fruit tree species widely distributed across African countries. Several studies have investigated different aspects of the species, but there is a lack of synthesis on the current state of available literature and prospects for sustainable conservation and management of the species. Using the PRISMA approach for sy...
The density of wood is a key indicator of the carbon investment strategies of trees, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls remain poorly understood, preventing accurate predictions of global forest carbon stocks. Here we analyse information from 1.1 mil...
Background: Ritchiea capparoides is a fast-growing ornamental climbing shrub native to Africa, classified under the Capparaceae family. Despite its importance, it is commonly associated with genera Maerua and Crateva. This bibliometric analysis assesses the spatial and temporal distribution of scientific knowledge concerning these genera, utilizing...
Random forests (RF) have been widely used to predict spatial variables. Several studies have shown that spatial cross-validation (CV) methods consistently cause RF to yield larger prediction errors compared to standard CV methods. This study examined the impact of species characteristics and data features on the performance of the standard RF and s...

The density of wood is a key indicator of trees’ carbon investment strategies, impacting productivity and carbon storage. Despite its importance, the global variation in wood density and its environmental controls remain poorly understood, preventing accurate predictions of global forest carbon stocks. Here, we analyze information from 1.1 million...
Vitex doniana is one of the highly demanded traditional vegetables in West Africa, yet supply is still too low to meet demand. Among the reasons for the low supply is the constraint related to the propagation of the species. Sexual propagation of this species is limited by seed dormancy which hinders cultivation. To achieve homogeneous germination...
Forests are a substantial terrestrial carbon sink, but anthropogenic changes in land use and climate have considerably reduced the scale of this system¹. Remote-sensing estimates to quantify carbon losses from global forests2–5 are characterized by considerable uncertainty and we lack a comprehensive ground-sourced evaluation to benchmark these est...
Demographic pressure and human activities are having significant impacts on biodiversity conservation. As traditional farmlands have challenges of coupling crop production and conservation of biodiversity, this study assessed traditional farmlands in regard to their typology and impacts on conservation of tree species. A line tran-sect of 26 km was...

We used simulated...
Haphazard and opportunistic species occurrence (PO) data are widely used in species distribution models (SDMs) instead of high-quality species data gathered using appropriate and structured sampling methods, which is expensive and often spatially limited. Despite their widespread use in ecology, PO data are prone to errors and uncertainties, such a...
