Waterbird diversity, densities, communities and seasonality in the Kalahari Basin, Botswana

Journal of Arid Environments, 1999
Abstract 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

Spatially Diverse Water Levels Enhance Habitat Heterogeneity for Wintering Waterbirds

Freshwater Biology
ABSTRACT1. Rising global temperatures and the increasing frequency of climate extremes pose significant challenges to waterbird conservation. These effects might be mitigated by managing habitat heterogeneity through diverse water levels in waterbird habitats. East Dongting Lake (EDL), a critical wintering site within the East Asian–Australasian Flyway,

Seasonal Variations in Waterbird Diversity and Threats to the Barotse Floodplain

University of Zambia Journal of Agricultural and Biomedical Sciences
This 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.

Abundance and diversity of the waterbird community in a managed wetland ecosystem

2004
The 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
