Climate change is predicted to affect species distribution worldwide. Most of the methods used evaluate such impact so far assume that respond environmental gradients in a uniform way along their range. Because populations occupying different niches may differ response climate due local adaptation, accounting for intraspecific variation models (SDMs) yield more reliable predictions widely distributed species. Pterocarpus erinaceus Poir highly valued but endangered tree species, which occurs...
Abstract Climatic and edaphic effects are increasingly being discussed in the context of biodiversity-ecosystem functioning. Here we use data from West African semi-arid tree savannas contrasting climatic conditions (lower vs . higher mean annual precipitation-MAP temperature-MAT) to (1) determine how climate modulates species richness on aboveground carbon (AGC); (2) explore AGC relate with soil variables these conditions; (3) assess influence directly, and/or indirectly through stand...
The increasing rate of land use intensification and the rising evidence climate change impacts raise concerns about viability valued non-timber forest product (NTFP)-providing trees. This calls for assessment current status future trajectories their populations. Using population data collected from three land-use types (e.g., grazing lands, riverine areas natural forest) in western Tigray, we evaluated vulnerability multipurpose baobab tree (Adansonia digitata L.) to human disturbances...
Abstract Aim Despite mounting empirical evidence regarding the positive effects of forest structural diversity (STR DIV ) on functioning, underlying biotic mechanisms and controlling abiotic factors remain poorly understood. This study provides first assessment interactive STR in species functional traits aboveground biomass (AGB) natural forests West East Africa. Location Time period 2014–2020. Major taxa studied Woody plants. Methods Using data from 276 plots 7993 trees 207 distributed...
Abstract Land use/cover (LULC) changes have unequivocally affected biodiversity and ecosystem functioning, with enormous repercussions for human well‐being. However, the mechanistic ecological mechanisms underlying impact of land conversion on multifunctionality (EMF) remain insufficiently examined from perspective multiple attributes in dryland regions increasing deforestation rates. We investigated how natural forests savannas to agroforestry parklands alters relationships between...
Identifying the best genetic material across provenances and genotypes, particularly for vigorous seedling production, is a key aspect of domestication programs. This study aimed to (i) assess provenance tree-to-tree differences in germination performance Balanites aegyptiaca (ii) identify mother trees with seed sourcing. A total 1440 ripe fruits were collected from 36 two (Karimama Tanguieta) Benin one (Mouhoun) Burkina Faso. trial was conducted using split-plot design over 30 days....
Understanding the complex diversity of species and their potential uses in traditional agroforestry systems is crucial for enhancing productivity tropical ensuring sustainability natural resource base. The aim this study evaluation role home gardens parklands, which are prominent systems, conservation management biodiversity. Our quantified compared woody herbaceous perennial parkland under a sub-humid climate western Ethiopia. A sociological survey 130 household respondents revealed 14...
Abstract Aims: Mixed‐species forests are known to be highly productive systems because of their high species diversity, including taxonomic diversity (species richness) and structural diversity. Recent empirical evidence also points plant maximum height, as a functional trait that potentially drives forest above‐ground biomass (AGB). However, the interrelations between these biotic variables complex, it is not always predictable if attributes or metrics height would act most important...
The importance of terrestrial ecosystems for carbon sequestration and climate regulation is acknowledged globally. However, the underlying structural drivers are still not well understood, particularly across distinct tropical forest where trees species have different growth habits potential to reach maximal size. In particular, how important tree size classes in contributing stand aboveground (AGC) remains unclear ecosystems. Here, we hypothesized that (i) would contribute differently AGC...
The adverse impacts of ecosystem degradation have raised the need for forest landscape restoration (FLR) to be included in international sustainability agendas. However, path towards successful FLR implementation faces numerous biophysical, socioeconomic and governance challenges because operates within complex socioecological systems. In present study, we review discuss context global environmental change. We propose a roadmap consisting five interlinked steps overcome these challenges: (1)...
Abstract Despite the importance of agroforestry parkland systems for ecosystem and livelihood benefits, evidence on determinants carbon storage in parklands remains scarce. Here, we assessed direct indirect influence human management (selective harvesting trees), abiotic factors (climate, topography, soil) multiple attributes species diversity (taxonomic, functional, structural) aboveground (AGC) stocks 51 drylands Benin. We used linear mixed-effects regressions structural equation modeling...
Riparian ecosystems are recognized as large reservoirs of biodiversity providing important ecosystem services. However, the relationship between tree species diversity and functions underlying ecological mechanisms have less been studied in riparian corridors. This study assessed effect (taxonomic, functional, phylogenetic) on (habitat quality–HbQ aboveground carbon–AGC) across environmental gradients (distances to stream bed) conservation status. Data were collected from 96 inventory plots...
Abstract Given recent and projected climate change, the study of adaptation mitigation strategies which involve ecologically economically important plant species is urgently needed. Faidherbia albida (Delile) A. Chev. a both economic ecological importance. We use 229 locational records gathered in dry highlands Ethiopia, nineteen environmental variables modelling program MaxEnt to model present possible future distributions this species. To distributions, we used two emission scenarios...
The early growth stage is critical in the response of trees to climate change and variability. It not clear, however, what metrics are best define early-growth sensitivity assessing adaptation strategies young forests change. Using a combination field experiments modelling, we assessed two promising afforestation species, Jatropha curcas L. Moringa oleifera Lam., by analyzing their predicted climate–growth relationships initial years after planting on degraded cropland semi-arid zone Benin....
