Root mechanical traits, including tensile strength (Tr), strain (εr) and modulus of elasticity (Er), are key functional traits that help characterize plant anchorage the physical contribution vegetation to landslides erosion. The variability in these is high among tree fine roots poorly understood. Here, we explore variation root as well their underlying links with morphological (diameter), architectural (topological order) anatomical (stele cortex sizes) traits. We investigated four...
Plant root traits are diverse and variable, the way in which they interact has consequences for fundamental functions such as anchorage, or services soil fixation. Here, we characterize mechanical related to anchorage (tensile strength, strain, stiffness toughness) at both intra‐ inter‐specific levels examine how covary with other economics space. We grew twelve herbaceous species from contrasting taxonomical families a common garden experiment. For each species, excavated systems measured...
Abstract Main conclusion Emblematic Vachellia spp. naturally exposed to hyper-arid conditions, intensive grazing, and parasitism maintain a high nitrogen content functional mutualistic nitrogen-fixing symbioses. AlUla region in Saudi Arabia has rich history regarding mankind, local wildlife, fertility islands suitable for leguminous species, such as the emblematic desert trees. In this region, we investigated characteristics of legumes two nature reserves (Sharaan Madakhil), at one...
Characterizing the above- and belowground carbon stocks of ecosystems is vital for a better understanding role vegetation in cycling. Yet studies on forest at high altitudes remain scarce. We examined partitioning trees growing mixed montane/upper montane French Alps. Field work was performed three forests along gradient both altitude (1400 m, 1700 2000 m) altitude-induced species composition (from lower Abies alba Fagus sylvatica to higher Picea abies Pinus uncinata). inventories root...
<title>Abstract</title> Hot deserts impose extreme conditions on plants growing in arid soils. Deserts are expanding due to climate change, thereby increasing the vulnerability of ecosystems and need preserve them. Arbuscular mycorrhizal fungi (AMF) improve plant fitness by enhancing water/nutrient uptake stress tolerance. However, few studies have focused AMF diversity community composition deserts, soil land use parameters affecting This study aimed comprehensively describe ecological...
Sampling for Digital Soil Mapping is an expensive and time-constrained operation. It crucial to consider these limitations in practical situations, particularly when dealing with large-scale areas that are remote poorly accessible. To address this issue, several authors have proposed methods based on cost constraints optimization reduce the travel time between sampling sites. These focused optimizing access associated each sample site, but not explicitly addressed field work required whole...
Saudi Arabia has implemented ambitious environmental protection programs by creating numerous nature reserves throughout the country. Establishment of latter led to farm abandonment and initiation ecosystem recovery processes. Agricultural practices are known impact structure physicochemical properties soils while also often markedly affecting natural restoration Moreover, weed proliferation in crop fields may modify soil seed banks (SSB), thereby impacting subsequent vegetation recovery....
Background: Human activities such as agriculture are known to markedly affect natural ecosystems, including plant communities and soil properties. Biological reduced in hot, hyper-arid ecosystems compared temperate tropical climatic conditions. Anthropogenic disturbances therefore have greater impacts on the ecosystem’s recovery potential. This study aimed assess diversity of post-agriculture Sharaan Nature Reserve (SNR), located northern Saudi Arabia. Methods: Three types habitats...
Abstract Human activities have affected the surrounding natural ecosystems, including belowground microorganisms, for millennia. Their short‐ and medium‐term effects on diversity composition of soil microbial communities are well‐documented, but their lasting remain unknown. When unoccupied centuries, archaeological sites appropriate studying long‐term past human occupancy compartment. In this work, chemical bacterial compositions were compared between Roman fort Hegra (Saudi Arabia)...
