“…Therefore, for this study, land cover, NDVI, NDMI, and slope were chosen as the most indicators for assessing herbivorous Anseriformes' habitat suitability in this study area. These indicators are the important parameters that help to study a quantitative way of migratory bird suitability status [38,52].…”

“…Habitat suitability is also a crucial and sensitive index explaining local habitat use [37]. It could have a wide variety of applications in managing biodiversity of species and conservation planning design [38]. Despite improving the ecological environment and biodiversity conservation, most traditional suitability models have focused on the occurrence and have provided relatively qualitative information on species' habitat suitability [39].…”

“…Knowledge of waterbirds' habitat requirements [57,58] is crucial to assess their habitat suitability effectively. As a result, previous studies consider several factors while determining species' or groups' of species habitat suitability [38,59,60]. However, assessing waterbird habitat suitability by considering several factors has yet to be further explored in Poyang Lake.…”

To design a good conservation strategy for herbivorous Anseriformes wintering in Poyang Lake, knowledge of habitat suitability is essential. Therefore, this study aimed to assess the habitat suitability of herbivorous Anseriformes of China’s Poyang Lake. Landsat images with a resolution of 30 m downloaded from the United States Geological Survey, and other ancillary data were used. The ENVI 5.3 software and ArcGIS 10.2 software were used for preprocessing, classifying the satellite image, and mapping habitat suitability. The study reveals that land cover types were divided into vegetation, mudflats, water, and sand. Similarly, the study area’s habitats were also divided into unsuitable, fair, good, and best grades. However, the distribution of the habitat suitability for each grade reveals significant spatial variations. For instance, vegetation indicated the areas with the best habitat grade, followed by mudflats, and these areas cover (47.93%, 2015 and 55.78%, 2019) the majority of the study area. The unsuitable grades cover the smallest areas (0.48%) of the lake. Similarly, this study results showed a slight change in habitat suitability areas. Therefore, this study highlighted that Poyang Lake has valuable importance for the conservation of herbivorous Anseriformes. Extending the years of study and including some ecological variables from different stopovers could improve the results.

Dams have made great contributions to human society, facilitating flood control, power generation, shipping, agriculture and industry. However, the construction of dams greatly impacts downstream ecological environments and nearby marine areas. To summarize these impacts, this review used recent research to comprehensively analyze how dam construction has affected river hydrology, geomorphology, and ecosystem of downstream reaches globally. Effects of dams on ecosystems occur through reduced river flow, reduced sediment flux, altered water temperature, changed estuary delta, altered composition and distribution of nutrients, altered structure and distribution of phytoplankton populations, caused habitat fragmentation, and blocked migration routes in river sections and adjacent seas. Besides, exploring new reservoir management strategies (including targeted control of dam storage and flushing sediment operations), banning fishing activities, and removing unnecessary dams (obsolete or small dams) are becoming crucial tools for ecosystem restoration.

“…Hydrological change in Lake has a consequence on the ecological suitability, biodiversity, and landscape. Wu et al (2021) noted that Lake water level increase due to water release from impoundment during the middle of dry season had a negative influence on habitat suitability and resulted in Lake landscape pattern change (Wu et al, 2020a). In other aspects of hydrological change, the early dry season influenced landscape pattern (wetland vegetation expansion) and wetland biota, biodiversity, and ecological service such as habitat for migrating fish and birds (Wu et al, 2017(Wu et al, , 2020b.…”

significant positive interaction, while forest and water bodies had a substantial and slight negative relation to mean annual rainfall, respectively. Vegetation, bareland, urbanization, and agriculture/farmland are directly responsible for the hydrologic variation. LC change significantly affected hydrologic regimes and the distribution of spatial rainfall is correlated significantly to LC change pattern. Besides, due to the lack of LC management practices, the impact continues to propagate. Hence, this review helps to portray the potential implications and extent of effects of changes in LC on the hydrological regimes. As a result, the implementation of sound water management strategies and practices in response to changing environments to resurrect water scarcity and mitigate flood and sediment are needed straightaway.
