Eremopezus more than a large emu—and more than 10 kg—slightly more than the largest living storks (which reach over 150 cm in height) and the shoebill. The general limit for weight in flying birds is at about 25 kg, the exceptional "Argentavis magnificens" with its size and weight of a good-sized adult human notwithstanding as it evolved under unusual ecological conditions. Large males of the kori bustard ("Ardeotis kori") and great bustard ("Otis tarda") are perfectly capable of flight, while weighing in excess of 20 kg. A wing loading of c. 25 kg/m is the known limit for bird flight under
Ascochyta tarda Ascochyta tarda Ascochyta tarda or Phoma tarda is a fungal plant pathogen that causes dieback and leafspot on coffee and was first observed in Ethiopia in 1954 (Stewart, 1957). It poses a potentially serious threat to coffee crops, but climate change may reduce the prevalence of environmental conditions favorable to its spread. Die-back is a condition in which a tree or shrub begins to die from the tip of its leaves or roots backwards, owing to disease or an unfavorable environment). Necrosis of both flowers and rosettes is also observed with this pathogen and this can significantly reduce crop yield.
