Abstract Recent studies showed great variations in both soil inorganic carbon (SIC) and organic carbon (SOC) in cropland across the North China Plain. This work was designed to test the hypothesis that hydrological processes associated with the Yellow River may be responsible for the differences in soil carbon dynamics over space. We selected 22 sites from the wheat-maize cropland across the Yellow River in the south North China Plain, and measured SOC, SIC, water-extractable organic carbon (WEO...
Abstract The landscape patch amount and configuration at the class level profoundly affect stream nitrogen (N) and phosphorus (P) concentrations in agricultural catchments, but their relationships and contributions to stream NP levels remain unclear. Here, we observed the stream water NP concentrations, stream flow, and landscape pattern at the class level in 11 catchments in a Chinese subtropical agricultural catchment during 2011–2017 to quantify their relationships and contributions. Pearson ...

Abstract Agricultural non-point source pollution (NPSP) is becoming a severe threat and seriously restricting the sustainable development of agricultural economy and rural environment in the Three Gorges Reservoir Areas (TGRA). However, limited studies have focused on agricultural NPSP management in TGRA, especially for integrated technology systems with TGRA characteristics. An integrated slopping land/paddy field/hydro-fluctuation belt eco-system (SPHES) was constructed using best management p...

Abstract In the last decades, western Iberian Mediterranean drylands have experienced a shift from extensive sheep to beef-cattle farming. In this 5-year study in Evora region (Southern Portugal), we investigated the role of livestock species in favouring grassland bird habitat suitability, starting from the hypothesis that livestock species complement bird habitat requirements under contrasting grazing rotation patterns and annual rainfall conditions. Field methods were based on bird counts and...

Abstract Some of the negative effects of agricultural intensification on biodiversity can be counteracted by the implementation of practices typically associated with organic farming. The efficiency of key ecosystem services, such as natural pest control or pollination, depends on biodiversity and could determine agricultural productivity and food security. In terrestrial ecosystems, both land use and topographic features are important filters in shaping taxa distribution. It is essential to ide...

Abstract The occurrence and dissemination of antibiotic resistance genes (ARGs) constitute a major concern worldwide, and pose crucial threats to public health. The current study focused on this issue in the agricultural soils of Wuliangsuhai watershed in China. A total of 33 ARGs, belonging to 8 major types, were identified in the soil samples, mexF, blaTEM, vanD, sulI, sulII, and oprJ being the predominant ones. The abundance of ARGs ranged from 2.18 × 10−6–1.9 × 10-2 copies/16S rRNA gene copi...

Abstract Ecosystem services provided by silvopastoral systems are mediated by specific management practices, environmental conditions, and overall design of the system. We hypothesized that selection of tree species affects understory forage nutritive value and productivity, light/shade environment, and microclimate. The silvopastoral system was located at the Center for Environmental Farming Systems in Goldsboro, North Carolina, USA. Three overstory tree-species were Pinus palustris (PP; longle...

Abstract Traditional land-use cessation allows the spread of invasive tall-grass species and thus leads to a reduction in grassland biodiversity. We hypothesized that long-term multi-year mowing of invaded grassland fosters the recovery of its taxonomic diversity and functional composition by reducing the dominance of the tall grass species Brachypodium rupestre, and that this change increases the pasture feed value. In 2010, we fenced part of a grassland, abandoned for about 30 years, invaded b...
Abstract Coffee is a key export commodity of East Africa, but average smallholders’ yields are low. To guide sustainable yield improvements of smallholders’ coffee systems, we investigated coffee yield components in three different types of coffee cropping systems along an altitude gradient (1100−2100 m.a.s.l.) during two production years (2015 and 2016). We selected 810 coffee trees distributed over 27 farms and monitored number of stems per tree, fruit load per branch, productive nodes per bra...

Abstract Intensively-managed fruit-tree plantations consisting of low-stem trees have progressively replaced traditional high- and mid-stem orchards in Europe during the intensification of agriculture in the second part of the 20th century. Such perennial agricultural systems often form dense, homogeneous landscapes interspersed with open fields, urban areas and semi-natural structures. This observational study investigated the patterns driving landscape- and field-scale habitat preferences of b...
