Abstract Carbon (C) and nitrogen (N) are key to biogeochemical cycles in terrestrial ecosystems. Despite the negative effects of drought on multiple ecosystem processes, our understanding of the responses of C and N in plants, soil, and microorganisms to drought remains incomplete. Our meta-analysis of 379 observations from 79 studies revealed that the C and N concentrations and C:N ratios of plant organs, litter, and soil, and activities and stoichiometry of C- and N-acquiring extracellular enz...

Abstract Heat waves are problematic for grazing livestock systems in regions dependant on temperate (cool-season) pasture species, owing to the often minimal heat tolerance (thermotolerance) of these pastures. A field experiment in north-west Tasmania, Australia, tested the hypothesis irrigating more frequently reduces detrimental heat wave effects on perennial ryegrass (Lolium perenne L.) above-ground growth and short-term persistence (measured via basal frequency). Heat wave conditions were im...

Abstract Plants rely on spectral cues present in their surroundings, generated by the constantly changing light environment, to guide their growth and reproduction. Photoreceptors mediate the capture of information by plants from the light environment over a wide range of wavelengths, but despite extensive evidence that plants respond to various light cues, only fragmentary data have been published showing patterns of diurnal, seasonal and geographical variation in the spectral composition of da...

Abstract Drought-induced dieback episodes are globally reported among forest ecosystems but they have been understudied in scrublands. Chronically-stressed individuals are supposed to be more vulnerable prior to drought which triggers death. We analyzed drought-triggered dieback and mortality events affecting Mediterranean Juniperus phoenicea scrublands in two sites with contrasting climate and soil conditions located in Spain. We characterized the radial growth patterns of coexisting living and...

Abstract Climate warming has induced substantial advances in the onset of vegetation green-up in the northern hemisphere during recent decades. To date, however, the temporal changes in green-up date have not been adequately explained by the statistical relationships between green-up date and climatic factors, posing challenges in the attribution and prediction of phenological change. In this study, we thus turned to focus on autumn phenology, a critical biotic factor that is likely to affect th...

Abstract Current crop models usually need a lot of input information to simulate crop leaf area index and have relatively large simulation errors under soil water stress, which need to be improved. In this study, based on experiments conducted in glass soil columns and field under rainout shelters in four years (2012-2016) in Yangling, Shaanxi Province in China, we attempted to establish a dynamic model for simulating leaf expansion and senescence of winter wheat under soil water stress. First, ...

Abstract Continuous N2O flux acquisition is crucial to enrich our knowledge of the complex mechanisms underlying the annual greenhouse gas budget and to refine their estimation. N2O flux measurement methodologies at high temporal resolution, i.e. micro-meteorology methodologies, are still scarce and may exacerbate the lack of important data, especially during the night if the required turbulent conditions are not met. The static and automated chamber methodologies also lead to numerous gaps in a...

Abstract This study investigates the spatiotemporal relationships between growing season precipitation, maximum temperature, and minimum temperature anomalies on yield for corn (Zea mays), soybean (Glycine max), cotton (Gossypium), peanut (arachis hypogaea), and sweet potato (Ipomoea batatas) crops in the southeastern United States (SEUS). Detrended county-level yield data (1981–2018) were analyzed alongside spatially derived growing season (May-Oct) climate anomalies. Results reveal that the re...

Abstract Climate models predict significant changes in precipitation magnitude and timing in semi-arid grasslands, where soil carbon release is particularly sensitive to changing precipitation. Using data from a 4-year (2015-2018) field manipulation experiment, we explored effects of changed precipitation in different periods on soil respiration (SR) and heterotrophic respiration (HR) in a semi-arid grassland in northern China. The results showed that: (1) Decreased precipitation both in the ear...

This study aims to ascertain the uncertainties related to the spatiotemporal estimation of net radiation, and its components, using remote sensing data. Geographical focus is an irrigated agricultural hotspot of the Brazilian semiarid region, for which we also investigate the impact that contrasting land-cover types have on the upwelling radiation balance components, and hence on net radiation. Instantaneous (Rn) and daily (Rn,24) values of net radiation were estimated based on OLI/TIRS-Landsat-...
