The role of dung beetle species in nitrous oxide emission, ammonia volatilization, and nutrient cycling.

ABSTRACT: This study evaluated the role of dung beetle species alone or associated under different species on nitrous oxide (N₂O) emission, ammonia volatilization, and the performance of pearl millet [Pennisetum glaucum (L.)]. There were seven treatments, including two controls (soil and soil + dung without beetles), single species of Onthophagus taurus [Shreber, 1759] (1), Digitonthophagus gazella [Fabricius, 1787] (2), or Phanaeus vindex [MacLeay, 1819] (3); and their assemblages (1 + 2 and 1 + 2 + 3). Nitrous oxide emission was estimated for 24 days, when pearl millet was planted in sequence to assess growth, nitrogen yield (NY), and dung beetle activity. Dung beetle species presented greater N₂O flow of dung on the 6th day (80 g N₂O-N ha^-1 day^-1</
