DIVERSITY OF WATERBIRDS FROM COASTAL AGROECOSYSTEM, CENTRAL KERALA, INDIA
UTTAR PRADESH JOURNAL OF ZOOLOGY, 2022Coastal Agroecosystem (Pokkali Farming) has been identified with a high waterbird density. In this study, we analysed the waterbird diversity and their current threats in Pokkali farming during February 2021- January 2022. Bird survey was carried out using the Direct Observation Method, Point Count Method and Line Transect Method. A total of 31 species

Whole‐community facilitation by beaver: ecosystem engineer increases waterbird diversity
Aquatic Conservation: Marine and Freshwater Ecosystems, 2014ABSTRACTWetlands are rich in biodiversity, but globally threatened. After a long period of regional extirpation, beavers have recently returned to many European areas and are now restoring wetlands. The beaver is remarkable regarding the large impacts it has not only on individual species but on entire communities and ecosystems.

The Influence of the Creation of a Lagoon on Waterbird Diversity in Urdaibai, Spain
Waterbirds, 2014Abstract Restoration and the creation of artificial wetlands can mitigate the loss and degradation of natural wetlands. The chief wetland areas in northern Iberia are the estuaries situated along the coast of the Bay of Biscay. These areas are tidal in nature and often small in size.

Waterbird community composition, abundance, and diversity along an urban gradient
Landscape and Urban Planning, 2018Abstract Urban riparian corridors have the capacity to maintain high levels of bird abundance and biodiversity. How riparian corridors in cities are used by waterbirds has received relatively little focus in urban bird studies. The principal objective of our study was to determine how habitat and landscape elements affect waterbird biodiversity in an

Diversity of wintering waterbirds enhanced by restoring aquatic vegetation at Shengjin Lake, China
Science of The Total Environment, 2020The restoration of planted vegetation contributes towards improving the habitat quality of waterbirds and enhancing the diversity of their communities. Thus, the success of projects attempting to restore aquatic vegetation could, in part, be quantified by evaluating the community structure of wintering waterbirds.

Abundance and diversity of the waterbird community in a managed wetland ecosystem
2004The waterbird community was studied in the Comacchio Lagoon for wildlife conservation and ecosystem wise use purposes. The studied area, divided into 33 sectors, covered little less than half of the 120 km2 total surface and all types of habitat and human management. Censuses were carried out 2-4 times every month during three years; average numbers of

Seasonal Variations in Waterbird Diversity and Threats to the Barotse Floodplain
University of Zambia Journal of Agricultural and Biomedical SciencesThis study explored waterbird diversity and associated threats in the Barotse Floodplain, Zambia, a critical wetland in the Zambezi River Basin. Field surveys conducted along a 202 km transect during the cold-dry and hot-dry seasons revealed higher waterbird diversity in the hot-dry season, as indicated by the Shannon-Wiener Index.

Environmental Monitoring and Assessment, 2018
Assessment of the effectiveness of nature conservation measures is a crucial step to ensure that the actions undertaken have achieved the expected results. Depending on the results of such evaluations, managers may need to reframe or even change their approaches.

Seasonal Diversity and Population Status of Waterbirds in Phewa Lake, Pokhara, Nepal
Journal of Wetlands Ecology, 1970The study (2007-08) was carried out in Phewa Lake which is one of the largest lake systems in Nepal to evaluate seasonal diversity and population status of waterbirds. A total of 39 waterbird species belonging to 17 families of 5 orders was recorded. The highest number of species (31 species) was found in December and January.

Waterbird diversity, densities, communities and seasonality in the Kalahari Basin, Botswana
Journal of Arid Environments, 1999Abstract Surveys in all major wetlands in Botswana (52,127 birds of 104 species on 10,672 ha of water and along 1782 km of shoreline) showed that waterbird diversity (from rarefaction) and densities were highest at small ephemeral endorheic pans. Oligotrophic waters in the Okavango Delta had similar diversity, but 10 times lower density. Large saline
