The analysis of networks of ecological throphic transfers is a useful complement to simulation modelling in the quest for understanding whole-ecosystem dynamics. Throphic networks can be studied in quantitive and systematic fashion at several levels. The purpose of this paper is to investigate a system of parabolic equations with discrete time delays describing a simple throphic food network wh...

Exposure to ultraviolet (UV) radiation may cause the significant degradation of many materials. UV radiation causes photooxidative degradation which results in breaking of the polymer chains, produces free radical and reduces the molecular weight, causing deterioration of mechanical properties and leading to useless materials, after an unpredictable time. Polystyrene (PS), one of the most impor...

Forests acting as carbon storage and sequestration play an essential role in the global nutrient cycle, which fungi are active participants. The forests cover almost all regions from boreal, temperate to subtropical tropical forests. relative proportion of sequestrated forest soil varies approximately 85% terrestrial pool boreal 60% 50% rainforests. Fungi decomposers organic matter root-associa...

The emerald ash borer is causing dramatic losses following its introduction into North America, with hundreds of millions trees killed. Attacked lose wood integrity rapidly after infestation and are prone to failure. aim this study was investigate the degrading potential Basidiomycota fungi previously found associated EAB galleries. Laboratory soil agar microcosm experiments showed that many wh...

Soils are important reservoirs for potential human pathogens and opportunistic fungi such as the dermatophyte or dimorphic in order Onygenales. In soils, these taxa decomposers but many of them have to cause respiratory skin diseases humans and, some cases, systemic infections. Even so, factors that determine biogeography ecology Onygenales remain largely undocumented. To address this knowledge...

The formation of a steppe phytocenosis on marginal lands is an important stage in the restoration landscape. Analysis composition bacterial communities rhizosphere six plants collected removed from agricultural land use showed similarity dominant phylotypes ( Pseudomonadota (Proteobacteria) , Actinomycetota (Actinobacteria), Bacillota (Firmicutes), Bacteroidota (Bacteroidetes), Verrucomicrobiot...

Aerobic composting and vermicomposting processes were compared in the co-composting of durian shells citrus peels. For decomposers, microorganism catalyst from Land Development Department, i.e., LDD1 catalyst, earthworms used. The moisture contents peels 84.6% 77.3%, respectively, pH relatively low, as these are sources potassium. experiments utilized four different reactors: (100%) reactor 1; ...

Cattle farming is one of the livestock business commodities in Indonesia. In production process, cattle farms produce waste form feces and leftover feed which can be processed such a way through decomposition process into organic fertilizer. The rate influenced by existing decomposer microbes. One microbes needed cellulolytic bacteria. research was conducted to obtain potential bacterial isolat...

? Fine roots and mycorrhizal fungi may either stimulate leaf litter decomposition by providing free-living decomposers with root-derived carbon, or slow through nutrient competition between saprotrophic fungi. We reduced the presence of fine their associated in a northern hardwood forest New Hampshire, USA soil trenching. Plots spanned gradient from 96% arbuscular (AM) associations to 100% ecto...
