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...

Acipenser stellatus is one of the most invaluable species of Sturgeon fishes in the world. The purpose of this study was to identify the resident microbial community from the gastrointestinal tract (GIT) of Acipenser stellatus. One hundred and twenty three fungi were isolated from the GIT of 7 Acipenser stellatus samples including Aspergillus spp (45.5%), Trichoderma spp (8.9%) and Cladophialop...

Diversity in Pistacia has been evaluated at all molecular levels using the internal transcribed spacer 1 (ITS1) marker three species (Pistacia atlantica subsp. atlantica; vera and terebinthus), compared with other species. Results showed that ITS amplification sequencing, followed by phylogenetic analyses, identify confirm their classification, which revealed it can be used as a marker. Our res...

Abstract How social and ecological factors are associated with variation in dominance style across species of animals has been studied frequently, but the underlying processes often not addressed. Theoretical research indicates that stronger spatial cohesion among individuals a group causes higher frequency fighting and, thus, through self-reinforcing effects winning losing fights, differentiat...

Abstract The present study objectified to evaluate the trophic relationships and possible aggressive mimicry involving Carnegiella strigata, marthae Gnathocharax steindachneri, in lowland forest streams. Samplings occurred November 2002, March August 2003 Amanã Sustainable Development Reserve (ASDR). total of 943 fish was caught, being 79.43% C. marthae, 3.18% strigata 17.39% G. steindachneri. ...
