Fungi from soils, such as Aspergillus and Penicillium, can be used as bioindicatorsfor biodiversity conservation. The aim of this study was to isolate and identify species of Aspergillus andPenicillium in soil, from the municipalities of Tupanatinga and Ibimirim, with dry forests, in the CatimbauNational Park. Five collections were performed in each area during the drought season of 2012, totaling 25soil samples per area. Fungi were isolated by suspending soil samples in sterile distilled water and plating onSabouraud Agar media plus Chloramphenicol and Rose Bengal, and Glycerol Dicloran Agar. Isolates wereidentified by morphological taxonomy in the Culture Collection Laboratory and confirmed by sequencing ofthe Internal Transcribed Spacer of rDNA. A total of 42 species were identified, of which 22 belong to the genusAspergillus and 20 to Penicillium. Penicillium isolates showed uniform distribution from the collecting area inTupanatinga, and the evenness indices found were 0.92 and 0.88 in Tupanatinga and Ibimirim, respectively.Among isolates of Aspergillus evenness, the value found in Tupanatinga (0.85) was very close to that found inIbimirim (0.86). High diversity and low dominance of fungi in soil samples was observed. These results contributedto the estimation of fungal diversity in dry environments of the Caatinga, where diversity is decreasingin soils that have undergone disturbance. 2016 artículo científico 0034-7744 https://www.redalyc.org/articulo.oa?id=44943437005 en http://www.redalyc.org/revista.oa?id=449 Revista de Biología Tropical application/pdf Universidad de Costa Rica Revista de Biología Tropical (Costa Rica) Num.1 Vol.64 |
