Airborne fungi in the region of Cubatão, São Paulo State, Brazil BJM
Schoenlein-Crusius,Iracema H.; Trufem,Sandra F.B.; Grandi,Rosely A.P.; Milanez,Adauto I.; Pires-Zottarelli,Carmen L.A..
From March/1993 to March/1995, airborne fungi were isolated from the "Vale do Rio Moji" (highly affected by the air pollution caused by fertilizer industries, steel works, cement factories and chemical products industries, among others) and from the "Vale do Rio Pilões" (less affected by the air pollution), both in the municipality of Cubatão, São Paulo State, Brazil, by exposing Petri dishes with potato dextrose agar medium, placed one meter from the ground, during 5 min. After 5 days of incubation at 20ºC, the colonies of the fungi were purified and identified, resulting in the identification of 39 taxa, three unidentified strains of Fusarium and non-sporulating cultures. A total of 28 taxa, one unidentified strain of Fusarium and non-sporulating fungi...

Biodiversity of Agaricomycetes basidiomes associated to Salix and Populus (Salicaceae) plantations Darwiniana
Romano,Gonzalo M.; Calcagno,Javier A.; Lechner,Bernardo E..
Although plantations have an artificial origin, they modify environmental conditions that can alter native fungi diversity. The effects of forest management practices on a plantation of willow (Salix) and poplar (Populus) over Agaricomycetes basidiomes biodiversity were studied for one year in an island located in Paraná Delta, Argentina. Dry weight and number of basidiomes were measured. We found 28 species belonging to Agaricomycetes: 26 species of Agaricales, one species of Polyporales and one species of Russulales. Our findings suggest that forest management practices on plantations of willow and poplar do not affect either the abundance or diversity of Agaricomycetes basidiomes.

Biological potential of fungi associated to Prays oleae in Trás-os-Montes (Northeastern region of Portugal) IPB - Escola Superior Agrária
Oliveira, Ivo; Baptista, Paula; Lino-Neto, Teresa; Bento, Albino; Pereira, J.A..
Olive groves represent an important fraction of the agricultural practices in Portugal, mainly in the region of Trás-os-Montes. Our work pretends to disclose the fungal diversity associated to one of the major olives pests, the Prays oleae Bern. Besides evaluating the extent of the presence of entomopathogenic fungi, we also intend to reveal other promising fungi with potential to be used as biological control agents. In order to achieve this goal, larvae and pupae of the three generations of P.oleae were collected from several orchards. Whenever a fungal agent was associated to the cause of death, we proceeded to the preparation of fungal pure cultures, DNA isolation, amplification and sequencing of their ITS region for species identification. High fungal...

Effect of soil tillage on diversity and relative abundance of macrofungi associated with chestnut in the northeast of Portugal IPB - Escola Superior Agrária
Baptista, Paula; Martins, Anabela.
European chestnut (Castanea sativa Mill.) is a forest tree of great economic interest for wood and fruit production in the north east of Portugal. In order to maintain the soil free of weeds farmers traditionally practice several superficial tillages along the year. Phytossanitary problems mainly related with increasing Phytophtora cinamomi contamination of soils are progressively changing these practices. The present work intend to evaluate the effect of two different soil management (tillage vs. non tillage) of chestnut orchards on the macrofungi diversity and relative abundance. Two Castanea sativa orchards were selected (one tilled and one non tilled) and five plots of 100m2 each were delimited for macrofungi harvesting. During Autumn – Winter of...

Fungal diversity associated to Prays oleae in Trás-os-Montes (Northeastern region of Portugal). A survey of potential entomopathogenic fungi IPB - Escola Superior Agrária
Oliveira, Ivo; Baptista, Paula; Pereira, Susana; Lino-Neto, Teresa; Bento, Albino; Pereira, J.A..
Olive groves are one of the main agricultural activities in the Portuguese region of Trás-os-Montes. They occupy a very large area, where new biological agricultural practices have been increasingly applied. In order to control the pests that attack this culture, using methods that do not rely on chemical substances, an effort must be conducted to achieve new processes. One of the most important pest in the olive groves in this region is the olive moth (Prays oleae Bern.), responsible for high losses in olive yields. One of the promising approaches to control this pest is the use of entomopathogenic fungi that naturally occur in the olive orchards and are able to infect and kill olive moths. The present work intends to evaluate the diversity of fungal...

Microbial diversity in an Oxisol under no-tillage and conventional tillage in southern Brazil. Repositório Alice
BABUJIA, L. C.; SILVA, A. P.; NOGUEIRA, M. A.; HUNGRIA, M..
ABSTRACT: The no-tillage (NT) system of soil management is recognized as more sustainable than conventional tillage (CT), with an important role played by soil microorganisms. The objective of this study was to estimate differences in soil microbial diversity under NT and CT at different soil depths. For that, bacterial (16S rDNA) and fungal (18S rDNA) communities were evaluated by denaturing gradient gel electrophoresis (DGGE) in a 20-year field experiment established on an Oxisol in southern Brazil on which soybean has been grown in the summer and wheat in the winter. Soil samples were collected at the depths of 0-5, 5-10, 10-20 and 20-30 cm, and submitted to DGGE analyses. The results revealed lower similarity (28%) between bacterial communities in the...
