DIVERSITY AND THE MAIN ECOLOGICAL REQUIREMENTS OF THE EPIGEIC SPECIES OF FOREST ECOSYSTEMS IN THE SIBIU COUNTY, IN THE YEARS 2013-2014
2014
Epigeous insects in the “Dumbrava Sibiului” oak forest were captured between 2013-2014. From April to September in each year. 12 traps were installed in a circle 147 individuals collected belonged to 28 species and 6 families: Carabidae – 14 species (50.0%), 187 individuals (77.37 %), Staphylinidae – 7 species (25.0 %), 15 individuals (6.17 %), Silphidae – 3 species (10.72 %), 29 individuals (11.93 %), Elateridae – 1 species (3.51 %), 1 individual (0.41 % ), Scarabaeidae – 2 species (7.14 %), 8 individuals (3.29 %), Forficulidae – 1 species (3.51 %), 2 individuals (0.82 %)). Also, we presented in tables the ecological requirements of the species of Carabidae collected, the variation of thei…
Ecological role of mycotoxins produced by Fusarium graminearum : consequences of the presence of deoxynivalenol (DON) in crop residues on the soil mi…
2012
Fusarium graminearum is a plant pathogenic fungus, causing devastating disease “Fusarium head blight” (FHB) in cereals including wheat and maize. It also contaminates the grains with mycotoxins including deoxynivalenol (DON) which are toxic to human and animals. This disease has resulted in the serious losses in grain yield and quality. We established through a first bibliographic review that during off season fungus survives saprophytically on the crop residues (ecological habitat) and serves as primary inoculum for the next season crop. However, we noticed also that the literature was poor about the role mycotoxins could play in the establishment of F. graminearum in such a habitat. The m…
Quo Vadis, Orthotrichum pulchellum? A Journey of Epiphytic Moss across the European Continent
2022
Orthotrichum pulchellum is a species of epiphytic moss in which a significant expansion from the oceanic part of Europe to the east of the continent has been observed in the recent two decades. The improvement in air quality in Central and Eastern Europe, but also climate change, probably plays a role in this. This study shows what direction of its spreading we can expect in the future. Ecological niche modeling (ENM) is a widespread method to find out species niches in environmental and geographical space, which allows us to highlight areas that have a higher probability of occurrences of the studied species, based on identifying similar environmental conditions to those already known. We …
