Abstract The leaf economics spectrum 1,2 and the global of plant forms functions 3 revealed fundamental axes variation in traits, which represent different ecological strategies that are shaped by evolutionary development species 2 . Ecosystem depend on environmental conditions traits comprise communities 4 However, ecosystem largely unknown, limits our understanding how ecosystems respond as a whole to anthropogenic drivers, climate variability 4,5 Here we derive set 6 from dataset surface...
Abstract Amplification of the hydrologic cycle as a consequence global warming is predicted to increase climate variability and frequency severity droughts. Recent large‐scale drought flooding over numerous continents provide unique opportunities understand ecosystem responses climatic extremes. In this study, we investigated impacts early 21st century extreme hydroclimatic variations in southeastern Australia on phenology vegetation productivity using Moderate Resolution Imaging...
Abstract Each year, terrestrial ecosystems absorb more than a quarter of the anthropogenic carbon emissions, termed as land sink. An exceptionally large sink anomaly was recorded in 2011, which half attributed to Australia. However, persistence and spatially attribution this remain largely unknown. Here we conducted an observation-based study characterize Australian through novel coupling satellite retrievals atmospheric CO 2 photosynthesis in-situ flux tower measures. We show 2010–11...
Abstract. Land surface phenological cycles of vegetation greening and browning are influenced by variability in climatic forcing. Quantitative spatial information on their is important for agricultural applications, wildfire fuel accumulation, land management, modeling, climate change studies. Most phenology studies have focused temperature-driven Northern Hemisphere systems, where shows annually recurring patterns. However, precipitation-driven non-annual arid semi-arid systems (i.e.,...
Abstract. Evapotranspiration (ET) of Amazon forests is a main driver regional climate patterns and an important indicator ecosystem functioning. Despite its importance, the seasonal variability ET over forests, relationship with environmental drivers, still poorly understood. In this study, we carry out water balance approach to analyse in their relationships energy drivers five sub-basins across Basin. We used situ measurements river discharge, remotely sensed estimates terrestrial storage,...
Tree–grass ecosystems are widely distributed. However, their phenology has not yet been fully characterized. The technique of repeated digital photographs for plant monitoring (hereafter referred as PhenoCam) provide opportunities long-term phenology, and extracting phenological transition dates (PTDs, e.g., start the growing season). Here, we aim to evaluate utility near-infrared-enabled PhenoCam structure (i.e., greenness) physiology gross primary productivity—GPP) at four tree–grass...
Plant functional diversity (FD) is an important component of biodiversity that characterizes the variability traits within a community, landscape, or even large spatial scales. It can influence ecosystem processes and stability. Hence, it to understand how why FD varies between ecosystems, along resources availability gradients climate gradients, across vegetation successional stages. Usually, assessed through labor-intensive field measurements, while assessing from space may provide way...
Ecosystem health is the goal of eco-environmental management, and its assessment necessary for improving regional ecological environments promoting sustainable development. However, previous studies on ecosystem have mainly concentrated rapidly developing urbanized areas, with very few having been conducted alpine pastoral regions. Taking Gannan region China as study area, based remote-sensing GIS technologies, we used entropy methods to calculate relative weights several indicators quantify...
Woody plants serve as crucial ecological barriers surrounding oases in arid and semi-arid regions, playing a vital role maintaining the stability supporting sustainable development of oases. However, their sparse distribution makes significant challenges accurately mapping spatial extent using medium-resolution remote sensing imagery. In this study, we utilized high-resolution Gaofen (GF-2) Landsat 5/7/8 satellite images to quantify relationship between vegetation growth groundwater table...
The interplay between terrestrial water storage and vegetation dynamics in arid regions is critical for understanding ecohydrological responses to climate change human activities. This study examines the coupling total anomaly (TWSA) greenness changes Hexi Corridor, an region northwestern China consisting of three inland river basins—Shule, Heihe, Shiyang—from 2002 2022. Utilizing TWSA data from GRACE/GRACE-FO satellites MODIS Enhanced Vegetation Index (EVI) data, we applied a trend analysis...
The global carbon cycle is highly sensitive to climate-driven fluctuations of precipitation, especially in the Southern Hemisphere. This was clearly manifested by a 20% increase terrestrial C sink 2011 during strongest sustained La Niña since 1917. However, inconsistencies exist between El Niño/La (ENSO) cycles and precipitation historical record; for example, significant ENSO-precipitation correlations were present only 31% last 100 years, often absent wet years. To resolve these...
Abstract Projected increases in temporal precipitation variability, including intra‐annual and interannual will likely have important impacts on terrestrial ecosystem productivity. The direction magnitude of these how they vary across biomes, however, remain largely uncertain. Here, we review published literature that investigated the effect different characteristics variability vegetation We first reviewed commonly used methods, manipulation experiments, process‐based modeling, data‐driven...
The upper Yellow River basin over the Tibetan Plateau (TP) is an important ecological barrier in northwestern China. Effective LULC products that enable monitoring of changes regional ecosystem types are great importance for their environmental protection and macro-control. Here, we combined 18-class classification scheme based on with Sentinel-2 imagery, Google Earth Engine (GEE) platform, random forest method to present new a spatial resolution 10 m 2018 2020 Basin TP conducted types....
