“…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.

“…These characteristics of mangrove patches are the primary determinants of its species composition, and for many animals, including birds, mangrove patches are important steppingstones (Hutchings & Saenger 1987;Kutt 2007). This is especially true for the mangrove birds that are good dispersers, for example, water birds (Morris 2012;Almeida et al 2016). By contrast, mangrove-dependent species or species with low dispersal ability are unlikely to move between mangroves separated by other habitat types or by relatively large distances (Kathiresan & Bingham 2001;Grose 2016;Chupil & de Araujo Monteiro-Filho 2018).…”

Local species turnover increases regional bird diversity in mangroves

Understanding patterns of species diversity and distribution is crucial for the development of adequate public conservation policies. Despite the conservation value of mangroves, we still have a limited understanding of the influence of the habitat characteristics and patch connectivity of mangroves on bird species composition and diversity at local and regional scales. Here we used 40 point counts in six mangroves in southern Brazil to test the effects of landscape connectivity and habitat characteristics on the composition and diversity of mangrove bird communities. We measured environment variables locally and calculated land cover to describe the landscapes in which the patches of mangrove habitat were inserted. We also generated spatial variables as proxies for connectivity. We found that local bird species richness was similar in the different mangroves, ranging from 22 to 33 species, but with more species being found in larger patches. The partitioning of the beta diversity revealed a high species turnover, indicating that each patch of mangrove contributes different species to the regional pool of 57 species. Variance partitioning analysis also indicated that the composition of the mangrove bird metacommunity is driven mainly by local patch dynamics, whereas habitat characteristics and connectivity had a minor influence. These findings indicate that the maintenance of multiple large patches of mangrove at a regional scale will ensure a high species turnover and is the key to the maintenance of a diverse regional biota.
