“…Based on the climate zone division, an uneven distribution of B. bassiana and B. pseudobassiana was revealed. Earlier studies indicated a strong association of B. bassiana with agricultural and B. pseudobassiana with forest ecosystems [ 24 , 25 ]. Our findings were consistent with these reports as the major species in the forest ecosystems were B. pseudobassiana , and the proportion of B. bassiana increased towards the southern (dfb) more agricultural areas ( Figure 2 B and Figure S3 ).…”

“…While studying the distribution and genetic diversity of Beauveria spp. in natural and agricultural ecosystems in China based on 641 isolates, 14 haplotypes of B. pseudobassiana and 13 haplotypes of B. bassiana were identified [ 25 ]. We found that several haplotypes detected in NER were more abundant and had wide distribution (T1B1.1 and T2B1.1), while others were less frequent and tended to occur mostly in the northern climate zone.…”

“…However, neither these methods nor ITS sequencing has provided sufficiently comparable data to infer interspecies and population genetic structures within Beauveria . Recent studies have been more consistent with the sequencing of nuclear intergenic locus Bloc being effectively mandatory for the determination of Beauveria phylogeny [ 3 , 24 , 25 ]. Most of Beauveria spp.…”

“…have been reported from particular geographical regions, but a few species (e.g., B. bassiana and Beauveria pseudobassiana S.A. Rehner and Humber) have worldwide distributions. Several studies have demonstrated a strong association of B. bassiana with agricultural and B. pseudobassiana with forest ecosystems [ 24 , 25 ].…”

The distribution and genetic diversity of 91 of Beauveria isolates collected during a long-term survey in boreal forests of northern European Russia was studied. Based on morphological and sequence analysis of TEF and Bloc loci, three Beauveria spp. were identified: B. pseudobassiana, B. bassiana, and B. caledonica, with abundance of 81, 11, and 8%, respectively. Through multilocus sequencing, four haplotypes of B. bassiana and two haplotypes of B. caledonica were detected. Twelve haplotypes of B. pseudobassiana with non-random distribution were identified. Two haplotypes of B. pseudobassiana were the most abundant and widespread occurring across the whole study area, whereas others tended to be more specific to either the north or south of the study area, indicating the presence of different subpopulations. For further analysis of these putative subpopulations, southern and northern areas were separated along the boundary of the Köppen–Geiger climate zones (dfb and dfc), and the genetic structure was examined by analysis of molecular variance and spatial autocorrelation. Molecular evidence of intraspecific recombination of B. pseudobassiana and B. bassiana across northern European Russia area was indicated.
