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.
基于对来自土壤和凋落物的微生物的超过 250 项研究中报告的曲霉属物种的计数，进行了卡方分析，以确定五个生物群落和五个纬度范围内的物种出现情况与预期分布的差异。然而，生物群落中整个属成员的分布并没有总体趋势，但是属的各个部分似乎具有明显的分布模式。大多数属于曲霉属、节丛孢属、黄皮层属和Circumdati 节的成员在沙漠土壤中的出现频率高于预期。森林、湿地或耕地土壤的物种出现没有明显的模式，尽管节丛孢属的成员在耕地土壤中相当罕见。大多数物种在草原土壤中的出现频率与预期相符或低于预期。该属的成员在亚热带/暖温带 26 至 35 度之间的纬度上出现的频率高于预期。大多数物种在较低纬度出现的频率与预期相符，而在 35 度以上的纬度出现的频率则低于预期。
