“…Vegetation is an important driver, providing food resources and hiding places; however, excessive vegetation cover can negatively affect waterbird survival [35]. Wetland area and shoreline length are strongly determinative of the extent of habitat in the fallow zone, which, as a confluence of aquatic and terrestrial ecosystems, provides a high diversity of niches and abundant food resources [13,41]. We found that all three of these factors were positively correlated with the species number and abundance of waterbirds within a certain range.…”

“…The population status of such species can, thus, be employed as an indicator in habitat importance assessment. As a number of environmental factors directly affect the survival strategies of waterbirds and determine their habitat selection [12], an understanding of the relationship between these factors and habitat importance is fundamental for devising effective management strategies [13]. A further important conservation approach is to identify protection gap areas by overlaying the distributions of important habitats and protected areas using spatial analysis tools [14,15].…”

Wetlands are among the most important habitats of highly wetland-dependent waterbirds but are subject to ongoing habitat loss and degradation owing to intensified anthropogenic activities. The scarcity of human and natural resources makes effective habitat protection an important concern. Here, we aimed to investigate waterbird habitat protection methods for Anhui Province, China, a critical stopover and wintering area on the East Asian-Australasian Flyway that features rich wetland resources subject to significant habitat loss and degradation. We evaluated the status and importance of 306 wintering waterbird habitats and identified the key environmental influences and current protection gaps using the entropy weights method and generalized additive modeling. We found 73 important habitats for waterbirds in Anhui Province, which were classified into levels of importance (descending from I to V) according to the natural discontinuity method. Level I and Level II habitats were mainly located in the Yangtze River floodplain and Level IV habitats in the Huaihe River floodplain. The gap analysis showed that 42 important waterbird habitats had protection gaps, accounting for 57.53% of the total area. Waterbird habitat importance was significantly correlated with elevation, normalized vegetation index, lake area, and lake circumference but not with distance from roads or population density. The results of this study provide scientific information for waterbird habitat conservation planning, which is crucial for maintaining wetland ecosystem functions.

Context The intensification and expansion of human activities have caused profound changes in global wetlands and their associated aquatic bird communities. Understanding the mechanisms that drive the spatial assemblages of wetland birds is important for the development of effective conservation and management strategies. Objectives The overall objective was to evaluate the influence of wetland features such as size and distance to the nearest coastline, and landscape composition, configuration, and function in shaping waterbird richness and abundance in 43 Tunisian Important Bird and Biodiversity Areas (IBAs). Methods Systematic waterbird surveys on species abundance and richness at each IBA were carried out between December and January in 2020/2021 and 2021/2022. Satellite remote sensing indices were used to map wetlands and characterize the vegetation condition in the landscape surrounding them. Landscape metrics were used to describe the habitat configuration around the wetlands. Results Our results show that landscape composition, configuration and function have significant effects on waterbirds (i.e., shorebirds, waterfowl, wading birds, and open-water birds). We found that wetland surface area and distance to the coast were important factors influencing the richness and abundance of waterbirds. Our results also indicate that landscape diversity is an important predictor of waterbird richness and abundance, and that there is a significant interaction between wetland surface area and distance to the nearest wetland in explaining the richness and abundance of waterbirds. Conclusions This study provides evidence that the richness and abundance of waterbirds are robustly dependent on the interaction between wetland surface area and distance to the nearest wetland. Furthermore, local wetland characteristics (wetland surface area and distance to the nearest coastline), landscape composition (forest area and urban area), landscape configuration (spatial heterogeneity), and landscape function (maximum and minimum NDVI), significantly affect wintering waterbird communities. This study also highlights the importance of large and connected wetlands in conserving various bird communities in Tunisian IBAs and provides recommendations for their conservation and sustainable management.

Consistent but Delayed Timing of Precipitation Affects Community Composition of Prairie Pothole Birds and Aquatic Macroinvertebrates, but not Wetland Plants

The hydroperiod (i.e., the length of time ponded water is present) of prairie potholes largely depend on cumulative precipitation amounts, which are sensitive to climate change. Snowmelt runoff is the largest contributor to ponded water amounts. Thus, a change in precipitation timing -where a decline in winter/spring amounts is matched with an equivalent increase in summer amounts -can affect wetland hydroperiod. Between 2014 and 2015, cumulative precipitation amounts were near equivalent; however, precipitation amounts in 2015 were higher in the summer and lower in early spring when compared to climate normals. We sought to understand whether this change in precipitation timing could result in 1) a decline in wetland hydroperiod and 2) a change in the community composition of birds, aquatic macroinvertebrates and plants. Our ndings suggest a change in precipitation timing in 2015 could be tied to a decline in wetland hydroperiod. Additionally, bird and aquatic macroinvertebrate community composition changed between years. For birds, wetlands were dominated by wetland-dependent bird taxa in 2014, but by upland birds in 2015. In 2015, wetlands supported a nested subset of the macroinvertebrates present in 2014, and these were families that were either able to reproduce outside wetlands or could suspend metabolic activities under drought conditions. There was no change in the community composition of plants, and we hypothesize that this may be explained by their ability to utilize rhizomes from the previous year to survive this one-year change in their growing season.
