The biogeography of grebes
Abstract Grebes have a worldwide (cosmopolitan) distribution (Fig. 5.1), but they are poorly represented in tropical lowlands, and are absent from the high arctic (and Antarctic) regions. The strongholds of grebes are in the temperate steppe biomes and forest/steppe transitions, where the majority o...

| Summary: | Abstract Grebes have a worldwide (cosmopolitan) distribution (Fig. 5.1), but they are poorly represented in tropical lowlands, and are absent from the high arctic (and Antarctic) regions. The strongholds of grebes are in the temperate steppe biomes and forest/steppe transitions, where the majority of wetlands are shallow depressions, often with mineral-rich and slightly alkaline water, promoting high biological production. Grebes are abundant even in the wetlands of some of the high-altitude steppes in Central Asia and South America, to well above 4 000 m as. |
