“…These results do not only reflect the importance of climate and soil conditions to the distribution of P. erinaceus, but also extend this observation to semi-arid savanna ecosystems. The first striking result is the effect of silt content (Silt5) on the distribution of the species, reflecting the importance of this textural element on tree growth as it promotes water retention and reduced air circulation (O'Geen 2013, Bünemann et al 2018, Sanchez 2019). Further, we found precipitation (BIO18) and temperature (BIO3 and BIO6) contributing to the models, indicating a balanced influence of these variables on species distribution.…”

“…In particular, the available soil water capacity is a descriptor of the effective storage of water in the soil (Chandler et al., 2017). The saturated water content describes the storage beyond the field capacity of the soil (O'Geen, 2013). The bulk density is a metric of how densely packed are the soil ingredients which can affect the porosity of the soil (Archer & Smith, 1972).…”

“…The bulk density is a metric of how densely packed are the soil ingredients which can affect the porosity of the soil (Archer & Smith, 1972). The soil textures (sand/silt/clay fractions) are essential descriptors of the hydraulic transmissivity (O'Geen, 2013). Soil organic carbon is known to affect the hydraulic conductivity of a soil (Nemes et al., 2005).…”

The water stored in the root-zone layer is one of the most important water resources, as it supplies natural vegetation and crops with the vital water needed. Today, 75% of the total crop area harvested at global scale consists of nonirrigated crops (Portmann et al., 2010), which emphasizes the critical role of soil moisture in global food production and food security. From a natural system perspective, soil moisture is one of the most important components of the hydrological cycle, regulating energy flows and biogeochemical cycles, and hence plays a key role on plant growth (Seneviratne et al., 2010). Lacking systematic in situ measurements of soil moisture, research that focuses on agricultural drought assessment (

“…"Water is the single biggest factor which determines the bulk electrical properties of materials in most Earth settings" stated Davis and Annan [29] in 1989. The topsoil, which in agriculturally used fields corresponds to the plough layer, is rich in organic material and pore space between the solid particles, comprising the soil water [30]. In media where liquid water is present, dramatic changes of the GPR velocity can occur, complicating the imaging of buried structures, as described by Urban et al [19].…”

Archaeological Prospection with Motorised Multichannel Ground-Penetrating Radar Arrays on Snow-Covered Areas in Norway

The technical advancements of the past decade have rendered motorised, high-resolution ground-penetrating radar (GPR) investigations increasingly popular for archaeological research and cultural heritage management in Norway. However, the agricultural use of most survey areas limits the time available for fieldwork in spring and autumn and thus reduces the method's potential. An extension of the fieldwork period into the winter season would be desirable. The project "Arkeologi i veien?" aimed to develop practical solutions for efficient motorised GPR surveys on snow and to evaluate to what extent the thickness of the snow cover affects data quality. Four sites with known archaeological remains in the ground have been investigated under snowless conditions and with snow cover. The comparative data analysis showed that GPR surveys can result in useful data even on areas covered with one metre of snow. This study shows that different temperatures and resulting variable snow conditions can have a strong effect on the quality of the generated GPR data. The possibility for GPR measurements on snow offers the opportunity to extend fieldwork into the winter period without conflicting with the growing season; however, local weather and snow conditions have to be closely observed in order to obtain useful prospection data.
