“…Dissolved organic matter rich in nutrients, such as that released from organic horizons or dung pats in the presence of potworms or beetles, respectively 171,175,181 , has also been reported to increase total nitrogen and phosphorus and ammonium-nitrogen in mineral soil [181][182][183][184] , potentially alleviating microbial nutrient limitations and boosting the microbial pathway of MAOM formation. This notion is supported by studies reporting microbial biomass stimulation in the presence of potworms and dung beetles [185][186][187] (but see also Liiri et al 175 and Menendez et al 179 ). However, microbial traits considered important to the microbial pathway of MAOM formation, such as microbial C use efficiency 25 , have not been investigated in tandem with potworms or beetles and hardly with springtails 188 (Fig.…”

Fauna is highly abundant and diverse in soils worldwide, but surprisingly little is known about how it affects soil organic matter stabilization. Here, we review how the ecological strategies of a multitude of soil faunal taxa can affect the formation and persistence of labile (particulate organic matter, POM) and stabilized soil organic matter (mineral-associated organic matter, MAOM). We propose three major mechanisms - transformation, translocation, and grazing on microorganisms - by which soil fauna alters factors deemed essential in the formation of POM and MAOM, including the quantity and decomposability of organic matter, soil mineralogy, and the abundance, location, and composition of the microbial community. Determining the relevance of these mechanisms to POM and MAOM formation in cross-disciplinary studies that cover individual taxa and more complex faunal communities, and employ physical fractionation, isotopic, and microbiological approaches is essential to advance concepts, models, and policies focused on soil organic matter and effectively manage soils as carbon sinks, nutrient stores, and providers of food.

This study examined how dung beetle species and assemblage affect nitrous oxide (N2O), ammonia volatilization, and pearl millet [Pennisetum glaucum (L.) R] performance. Seven treatments were applied in pot and they were two controls (only soil and soil + dung without beetles), single species of Onthophagus taurus (1), Digitonthophagus gazella (2), or Phanaeus vindex [MacLeay] (3); and their assemblages (1 + 2 and 1 + 2 + 3) respectively. After an initial trial assessing gas emissions, pearl millet was planted to assess growth, nitrogen yield (NY), and dung beetle activity after dung application. Dung beetle species increased N2O flow on dung on the 6th day (80 g N2O-N ha− 1 day− 1) compared to soil and dung (2.6 g N2O-N ha− 1 day− 1). Ammonia emissions varied with the presence of dung beetles (P < 0.05), and D. gazella had lesser NH3-N on days 1, 6, and 12 with averages of 2061, 1526, and 1048 g ha− 1 day− 1, respectively. The soil N content increased with dung + beetle application. Each pot with dung application affected pearl millet herbage accumulation (HA) regardless of dung beetle application, averages ranged from of 5 and 8 g DM pot− 1. A PCA analysis was applied to analyze variation and correlation to each variable, but it indicated a low principal component explanation (less than 80%), not enough to explain the variation in findings. The presence of dung beetles prior to planting improved pearl millet production by enhancing N cycling, although assemblages with the three beetle species enhanced N losses to the environment via denitrification.

“…Dung beetle taxa differ in their nesting techniques and are classified as dwellers, tunnelers, or rollers 12 , which have a major impact on ecological functions, such as dung removal efficiency 13 . Many of the beetle species excavate the soil in distinct ways, with varying diameters and sizes, resulting in different micro-environments with different GHG fluxes 14,15 and enhanced nutrient cycling by transferring soil carbon more efficiently and favouring bacterial soil diversity 12,16,17 .…”

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) compared to soil and dung (2.6 g N2O-N ha−1 day−1). Ammonia emissions varied with the presence of dung beetles (P < 0.05), and D. gazella had less NH3−N on days 1, 6, and 12 with averages of 2061, 1526, and 1048 g ha−1 day−1, respectively. The soil N content increased with dung + beetle application. Dung application affected pearl millet herbage accumulation (HA) regardless of dung beetle presence, and averages ranged from 5 to 8 g DM bucket−1. A PCA analysis was applied to analyze variation and correlation to each variable, but it indicated a low principal component explanation (less than 80%), not enough to explain the variation in findings. Despite the greater dung removal, the largest species, P. vindex and their species combination, need to be more studied to get a better understanding about their contribution on greenhouse gases. The presence of dung beetles prior to planting improved pearl millet production by enhancing N cycling, although assemblages with the three beetle species enhanced N losses to the environment via denitrification.
