Systematics of Aspergillus species of subgenus Nidulantes in Iran
Aspergillus subgenus Nidulantes accommodates species of industrial and medical importance. Thirty isolates morphologically assigned to subgenus Nidulantes were studied, 25 isolated from cereals in the north and northwestern provinces and the rest from other substrates in Iran. Based on morphological and molecular data (sequences of the ITS rDNA and β-tubulin), nine species were identified belon...

Since the advent of the theory of evolutio n, o ne of the tasks of biology has bee n to i nvestigate the phyloge netic relatio nship betwee n species. This task is especially impor ta nt because all of the differe nces which exist betwee n species, whether i n morphology, physiology , or ecology, i n ways of behavior, or even i n geographical distributio n, have evolved , like the species thems...

Color patterns may range from brightly patterned to drab and camoufl aged. Th e composition of this family has changed since the description of...
متن کاملBiological Systematics
Biological systematics encompasses three distinct activities: taxonomy, classification (which may or may not be a reasonable reflection of phylogeny) and nomenclature (Fig. 1). Although systematists rigorously and distinctly practice these three components, they are often amalgamated under the term “taxonomy.” While the breadth of “taxonomy” is clearly understood among most practitioners, it ca...
متن کاملSystematics of leptospiraceae.
Leptospires are spirochetes that may be free-living saprophytes found in freshwater or may cause acute or chronic infection of animals. The family Leptospiraceae comprises three genera: Leptospira Leptospira Leptonema Leptonema, and Turneriella Turneriella. Within the genus Leptospira, three clades can be distinguished, of pathogens, nonpathogens, and an intermediate group. Leptospires are furt...
