| Abstract Mucorales comprises fungi commonly isolated as saprobes from soil, dung, stored grains and plants. Although these fungi have been studied in several countries, there are relatively a few reports of them in semi-arid areas. Therefore, the aims of the present study were to assess and compare the Mucorales communities in dung from different species and breeds of herbivores in the semi-arid of Pernambuco, based on the frequency of occurrence and species richness of these fungi. Samples of dung collected in the cities of Arcoverde, Serra Talhada and Sertânia were incubated in moist chambers in triplicate. Altogether, 24 taxa of Mucorales distributed in the genera Absidia, Circinella, Cunninghamella, Lichtheimia, Mucor, Pilobolus, Rhizopus and... |

| Flies occurring from dung of cow, horse and pig were investigated in Hokkaido, Japan. A total of 53 species of the flies belonging to 8 families was reared in two localities; these species were 2 of Stratiomyiidae, 8 of Sepsidae, 11 of Sphaeroceridae, 2 of Scathophagidae, 6 of Anthomyiidae, 22 of Muscidae, and 2 of Sarcophagidae. Numbers of species emerged from droppings of cow, horse and pig were 44, 23, and 23 species, respectively. Cow droppings in Otofuke yielded a large number and a wide variety of species of Anthomyiidae and Muscidae. Information concerning faunal composition in dung and dung preferences for each species is provided. |

| ABSTRACT Livestock urine and dung are important components of the N cycle in pastures, but little information on its effect on soil nitrous oxide (N2O) emissions is available. We conducted a short-term (39-day) trial to quantify the direct N2O-N emissions from sheep excreta on an experimental area of ryegrass pasture growing on a Typic Paleudult in southern Brazil. Four rates of urine-N (161, 242, 323, and 403 kg ha-1 N) and one of dung-N (13 kg ha-1 N) were applied, as well as a control plot receiving no excreta. The N2O-N emission factor (EF = % of added N released as N2O-N) for urine and dung was calculated, taking into account the N2O fluxes in the field, over a period of 39 days. The EF value of the urine and dung was used to estimate the emissions of... |
