根据250多项土壤和凋落物微真菌研究中报告的曲霉菌种类计数，对5个生物群落和5个纬度范围内的物种出现情况进行了卡方分析，以确定与预期分布的差异。整个属的成员在生物群中的分布没有总体趋势，但该属的个别部分似乎具有明显的分布格局。在荒漠土壤中，曲霉属、Nidulantes组、黄足目和Cirumdati组的大多数成员出现的频率高于预期。在森林、湿地或耕作土壤中没有明显的物种出现模式，尽管Nidulantes组的成员在耕作土壤中相当罕见。大多数物种在草原土壤中的出现频率达到或低于预期频率。在亚热带/暖温带26度至35度之间的纬度地区，该属成员的出现频率往往高于预期。大多数物种在低纬度地区以预期的频率出现，在纬度超过35度的地区低于预期的频率。
Based on counts of Aspergillus species reported in over 250 studies of microfungi from soils and litter, chi-square analyses were conducted on species occurrence in five biomes and five latitude ranges to determine variations from expected distributions. There was no overall trend in distribution of the members of the entire genus by biome, however, individual sections of the genus appeared to have distinct distribution patterns. Most members of sections Aspergillus, Nidulantes, Flavipedes and Circumdati occurred at greater than expected frequencies in desert soils. There was no distinct pattern of species occurrence for forest, wetland, or cultivated soils, although members of section Nidulantes were quite rare in cultivated soils. Most species occurred at or below expected frequencies in grassland soils. Members of the genus tended to occur at greater than expected frequencies at latitudes in the subtropical/warm temperate zone between 26 and 35 degrees. Most species occurred at expected frequencies in the lower latitudes, and below expected frequencies in latitudes greater than 35 degrees.
