We investigated the composition and structure of fungal communities associated with leaf litter generated by Clusia nemorosa and Vismia guianensis that belong to phylogenetically-related botanical families and exist together in a remnant of the Atlantic Forest in Bahia, Brazil. Samplings were conducted during wet (June 2011) and dry (January 2013) seasons in Serra da Jibóia. The fungi were isol...

Epigeous fungal fruiting has important impacts on reproduction and ecosystem function. Forest disturbances, such as timber harvest, impact moisture, host availability, substrate which in turn may drive changes patterns community structure. We surveyed mushrooms 0.4 ha patch cuts (18 months post-harvest) adjacent intact hardwood forest northern New Hampshire, USA, to document the effects of harv...

Taxonomic studies of bambusicolous fungi in China and Thailand have resulted the collection three fascinating saprobic coelomycetes strains. Morphology coupled with combined gene analysis ITS, LSU, TUB2, TEF1-? DNA sequence data showed that they belong to genus Apiospora, family Apiosporaceae. A new species from Thailand, Apiospora mukdahanensis, records A. locuta-pollinis are herein described....

Abstract Ephemeroptera, Plecoptera and Trichoptera are three orders of freshwater macroinvertebrates with a short terrestrial adult life-stage that they use to disperse by flying upstream. This aerial dispersal can be assisted native riparian forest, but regional variation has not yet been empirically tested. In this study we compared the EPT community 153 sampling sites located in streams four...

Sungai Barito yang panjangnya sekitar 900 km merupakan sungai besar penting di Kalimantan. Penelitian dilakukan Sub Das Nagara, Marabahan dan Kuin. Berdasarkan perhitungan indeks keanekaragaman plankton pada Nagara untuk fitoplankton zooplankton termasuk dalam kategori perairan tidak tercemar, tercemar sedang berat, Kuin ringan sedang. Koefisien Saprobik β-Mesosaprobik, sedangkan nilai koefisie...

The genus Phoma Sacc. consists of important fungal plant pathogenic species occurring on economically important cultivated crops in spite of many other saprobic species. Thus, the aim of this study was to identify 35 isolates of Phoma species and related taxa collected from different hosts by means of morphological and molecular characters. Multi-locus phylogenetic analyses based on ITS1-5.8S-I...

امروزه علاقه به اعمال سبک مربی گری در میان مدیران سازمانها حال رشد است. سازمان ها دنبال این روش مدیریتی هستند تا با استفاده از شایستگی های گری، نیروی انسانی خود را متعهد ساخته و بهبودعملکرد فردی سازمانی نائل آیند. وجود این، هیچ تحقیق یا ادبیاتی زمینه ندارد که کدامیک عوامل بیشترین بهبود عملکرد برای ویژه بانک بوجود می آورند. حاضر راستای پاسخگویی چالش، صورت جامع نظام مند تمامی شاخص هایی حوزه موثر ...

The diversity and distribution of microfungal assemblages in leaf litter of a tropical Australian forest was assessed using two methods: (1) cultures were isolated using a particle filtration protocol (wet season 2001), and (2) fruit bodies were observed directly on leaf surfaces following incubation in humid chambers (wet and dry season of 2002). Four tree species were studied using both metho...

Homothallism (self-fertility) describes a wide variety of sexual strategies that enable a fungus to reproduce in the absence of a mating partner. Unisexual reproduction, a form of homothallism, is a process whereby a fungus can progress through sexual reproduction in the absence of mating genes previously considered essential for self-fertility. In this study, we consider the molecular mechanis...

Fungal type I polyketides (PKs) are synthesized by PK synthases (PKSs) and include well known secondary metabolites such as the anticholesterol drug lovastatin and the potent natural carcinogen aflatoxin. Other type I PKs are known to be virulence factors for some plant pathogens and pigments such as melanin. In this study, a phylogenomic approach was used to investigate the origin and diversit...
