Migratory birds - Connecting Wetlands and People
Management of migratory species succeeds where critically important sites are well managed along flyways. Migratory waterbirds depend on a range of secure sites from their breeding grounds to staging and nonbreeding sites that they use during their annual migrations. These birds depend on a range of natural and man-made wetland habitats - many are managed as nationally protected areas, Natura ...

Precipitation influences on uptake of a global pollutant by a coastal avian species
Climatic variation, including precipitation amounts and timing, have been linked to abundance and breeding success of many avian species. Less studied but also of significance is the consequence of climatic variability on the exposure and uptake of nutrients and contaminants by wildlife. We examined mercury (Hg) concentrations in nestling wood stork feathers in a coastal setting over a 16‐year ...

Species diversity of the Okavango Delta, Botswana
Abstract. In the Okavango Delta (about 28,000 km2) the number of identified species is 1,300 for plants, 71 for fish, 33 for amphibians, 64 for reptiles, 444 for birds, and 122 for mammals. The local occurrence of different species of these taxonomic groups in the Okavango Delta is mainly due to a hydrological gradient from permanent streams and swamps to seasonal floodplains, riparian ...

Mercury‐contaminated terrestrial spiders pose a potential risk to songbirds at Caddo Lake (Texas/Louisiana, USA)
Methyl mercury (MeHg) is an environmental contaminant that can have adverse effects on wildlife. Because MeHg is produced by bacteria in aquatic ecosystems, studies of MeHg contamination of food webs have historically focused on aquatic organisms. However, recent studies have shown that terrestrial organisms such as songbirds can be contaminated with MeHg by feeding on MeHg‐contaminated ...

Water Reuse
Water is an increasingly scarce resource for much of the World's population. Global warming, an increasing world population and generally increasing incomes mean the demand for water is likely to rise further. If current trends continue, we will use 40% more water by 2024 than we do now. In industrialised countries much of the water used for non-potable purposes such as industrial applications, ...
