Abstract Redesigning agrosystems to include more ecological regulations can help feed a growing human population, preserve soils for future productivity, limit dependency on synthetic fertilizers, and reduce agriculture contribution global changes such as eutrophication warming. However, guidelines redesigning cropping systems from natural make them sustainable remain limited. Synthetizing the knowledge biogeochemical cycles in ecosystems, we outline four that synchronize supply of soluble...
Abstract. Priming effects in soil science describe the influence of labile carbon inputs on rates microbial organic matter mineralisation, which can either increase (positive priming) or decrease (negative priming). While both positive and negative priming occur natural ecosystems, latter is less documented peer-reviewed literature overall impact balance vegetated ecosystems remains elusive. Here, we highlight three aspects need to be discussed ensure (rhizosphere) are correctly perceived...
Abstract Climate change currently manifests in upward and northward shifting treelines, which encompasses changes to the carbon (C) nitrogen (N) composition of organic inputs soils. Whether these changed will increase or decrease microbial mineralisation native soil matter remains unknown, making it difficult estimate how treeline shifts affect C balance. Aiming improve mechanistic understanding cycling regions experiencing shifts, we quantified priming effects soils high altitudes (Peruvian...
Abstract Tree lines in high latitudes and altitudes are considered sentinels of global change. This manifests accelerated encroachment trees shrubs enhanced plant productivity, with currently unknown implications for the carbon balance these biomes. Given large soil organic stocks many tree line soils, we here wondered whether introducing highly productive plants would accelerate cycling through rhizosphere priming effects if certain soils be more vulnerable to loss from positive than...
Abstract Ferns (Polypodiophyta) are an abundant floral element of the tropics with high sensitivity to environmental conditions and good indicators overall biodiversity. Here, we set out identify which geochemical factors determine fern diversity in a low-montane tropical rainforest Eastern Ecuador. We conducted field survey high-spatial resolution completing comprehensive inventory across two elevational ranges, combined biochemical characterisation underlying soils. While α-diversity was...
Abstract Recent opening of the La Thure quarry in Western Belgium allowed collection new data from a poorly outcropping area Belgian Frasnian platform. The studied section covers an interval extending falsiovalis to hassi s.l. Zones. Sedimentological analyses reconstruction depositional settings northwestern part Dinant Synclinorium after demise extended Givetian carbonate Two models are distinguished: (a) siliciclastic drowned platform during Early Frasnian; and (b) fore-reef setting...

This manifests accelerated encroachment trees shrubs enhanced plant productivity, with currently unknown implications for the carbon balance these biomes. Given large soil organic stocks many treeline soils, we here wondered whether introducing highly productive plants would accelerate cycling through rhizosphere priming effects if certain soils be more vulnerable to loss from positive than others....
Understanding how climate change will affect crop performance is critical to ensure global food security and sustainability. Empirical data key anticipate the impact of on cropping systems, but multifactorial experiments remain scarce. In this study, growth winter wheat was examined in two agricultural soil management systems: one with long-term low organic inputs other high inputs. The grown these differentially managed soils an Ecotron, where plant-soil mesocosms were subjected three...
Abstract Dryland ecosystems are particularly susceptible to the adverse effects of intensive agriculture, with tillage exerting a major impact on soil health and its biotic components. The implementation less disturbing management practices can be essential for preserving environment maintaining diverse communities microorganisms, micro- mesofauna, which contributors fertility. In this study, we assessed chemical properties, biodiversity functionality, wheat crop growth across gradient...
Abstract Arbuscular mycorrhizal fungi (AMF) are amongst the most studied plant symbionts and regularly found in terrestrial plants. However, global estimates of AMF abundance all land plants difficult because i) status many non-commercial, wild species is still unknown ii) numerous engage facultative symbiosis, meaning that they can, but do not always do, associate with mycorrhiza iii) can vary individuals one same at location, as well for different within a given genus or family. To gain...
In the field of satellite imagery, good image acquisition chains are constructed such that produced being transmitted from to ground is well sampled (in order achieve a posteriori restoration results for example). This means Nyquist-Shannon sampling theorem satisfied [1]. However this does not take into account properties signal be transmitted. Some recent works have used prior knowledge as its sparsity. new theory has recently been extensively in literature since it offers nice mathematical...
Abstract In high altitudes and latitudes climate change manifests in upward northward shifting treelines. This entails changes to the carbon (C) nitrogen (N) composition of organic inputs soils can increase or decrease microbial mineralisation native soil matter (positive negative priming effect). It is currently unknown whether observed treeline shifts will lead loss storage these ecosystems. We therefore investigated effects from (Peruvian Andes) (subarctic Sweden). a laboratory...
