Maintaining optimal ecological security in Dongting Lake Basin is of great significance to national projects Yangtze River Economic Belt Construction and Protection. Ecological quality the potential associated affecting factors are important contents Basin. In this research, remote sensing index (RSEI) were used analyze temporal spatial variation qualities during 2001–2019 determine factors. Results showed that overall fluctuated 2001–2019. The change intensities among different RSEI levels...
The Yangtze River Basin was among the areas most severely affected by widespread extreme drought in Northern Hemisphere 2022. Drought conditions this basin extended into wintering season, significantly influencing waterfowl habitat availability. Exploring how distributions and ecological niches respond to these changes wetland environmental underlying mechanisms are important for biodiversity conservation understanding processes. By integrating field observations, remote sensing, niche...
Irrational land use has triggered many serious ecological problems worldwide, especially in regions where human–land conflicts are prominent. However, the driving mechanisms at different spatiotemporal scales vary and have not been addressed detail. This study explored variations of landscape patterns from 1990 to 2020 Dongting Lake Ecological Economic Zone (DLEEZ) by land-use transfer matrix, pattern indices methods, etc. We also combined geographical detector geographically temporally...
Water regime is regarded as the primary factor influencing vegetation distribution in natural wetland ecosystems. However, effect of water change induced by large-scale hydraulic engineering on still unclear. In this study, multi-temporal TM/ETM+/OLI images and hydrological data from 1995 to 2015 were used elucidate how influenced East Dongting Lake (EDTL), especially after operation Three Gorges Dam (TGD) 2003. Using unsupervised supervised classification methods, three types land cover...
Wetland restoration is an effective way to recover degraded wetlands worldwide. The Dongting Lake wetland, important wintering habitat for waterbirds, has suffered considerable degradation due climate change and human disturbance during the last two decades; however, wetland projects have now been implemented improve waterbird diversity in Lake. Based on annual survey data (2012/2013–2019/2020), we aimed compare differences variables (e.g., sedge [Carex spp.] meadow area, mudflat water...
Abstract. Litter decomposition plays a vital role in wetland carbon cycling. However, the contribution of aboveground litter to soil organic (SOC) pool has not yet been quantified. Here, we conducted Carex brevicuspis leaf input experiment clarify intrinsic factors controlling and quantify its SOC at different water levels. The genus is ubiquitous global freshwater wetlands. We sampled this plant −25, 0, +25 cm relative surface over 280 d analysed pool. percentage dry weight loss...
Abstract Dongting Lake, an important wintering habitat for migratory waterbirds in the East Asian–Australasian Flyway, has suffered serious degradation recent decades. To restore habitats biodiversity conservation and flood control, 459 dykes were demolished 14 preserved 2017. However, direct impact of dyke demolition on was not comprehensively assessed. In this study, based annual waterbird census data (2013/14–2020/21), we compared differences areas species composition dyke‐demolished...
Abstract East Dongting Lake is a Ramsar site and particularly important wintering ground for herbivorous geese along the Asian‐Australasian Flyway. The operation of Three Gorges Dam has changed water regime significant impact on wetland ecosystems downstream. We studied responses two sympatric goose species, Lesser white‐fronted Anser erythropus Bean fabalis , to habitat change by investigating their food conditions, selection, diet composition in periods 2016/2017 2017/2018, which had early...
In lacustrine wetlands connected to rivers, the changes in flood regimes caused by hydrological projects lead community traits of dominant macrophytes and, consequently, influence structure and function wetland vegetation. However, trait responses timing duration disturbance have been rarely quantified. 2011–2019, we investigated plant species diversity, density, biomass three macrophyte communities ( Carex brevicuspis C.B. Clarke, Miscanthus sacchariflorus (Maxim.) Hackel, Polygonum...
Phenological mismatches between migratory birds and food availability driven by global warming have been found to influence the fitness population dynamics of several herbivorous goose species in Arctic breeding sites. However, effect phenological at wintering sites inadequately studied. We used long-term data explore consequences water regime changes on mismatch (i.e., days arrival geese timing optimal Normalized Difference Vegetation Index [NDVIopt]) detect relative role as a driver annual...
