  1. How air temperature affects flight initiation distance in arid-zone birds

    Arid zones, such as the Kalahari in southern Africa, are experiencing an increase in the number of hot days, as well as in the intensity of heat waves. Research is being conducted to try and understand how increasing temperatures will impact bird communities and population persistence in these …

  2. A study of the ecology of the Namaqua Sandgrouse and other arid-zone birds

    … the nesting habits and success of 11 coexisting arid-zone bird species were examined to test a variety of hypotheses regarding the relationship between nest-predation rate and nest site, nest density, predator-avoidance behaviour, stage of the nesting cycle and season, and degree of residency. …

  3. Effects of temperature and food availability on the reproductive ecology of an arid-zone bird

    For arid-zone birds that breed in spring and summer, the heightened energy, water, and time demands of reproduction and development coincide with the hottest period of the year. For these species, rapid anthropogenic climate warming is exacerbating trade-offs between thermoregulation and …
