The hierarchical system of forest ecosystem models based on the theory of individual-based (structured) models of populations and communities is briefly described. New self-thinning models are integrated with tree stand models within a hierarchical system of models, aimed at assessing (quasi-) stable states of a forest ecosystem under given environment and management. Within the structural mode...

Water is not only the essence of life and medium organisms but also environmental factor that shapes biocenoses, including plant communities [...]

For the collection of primeval forest relict species, you need to identify the old and dead wood stocks first, to check in another step their habitat tradition. In addition to a recent occurrence of stocks ‒ of at least 160 years old ‒, other factors also play an essential role, such as historical forms of utilization, complications in sylviculture like steep slopes or azonal location condition...

SummaryDespite the fact that bacteria of genus Bacillus isolated from soil have been studied for centuries, there are still topics not sufficiently covered or need further research. Most often, members food. In recent years, these begun to isolate various aquatic biocenoses ecosystems oceans, seas, estuaries, lakes, rivers. Studies such isolates indicate almost all species infected with bacteri...

Aphyllophoroid macromycetes are a key link in natural and artificial biocenoses, particular, forest ecosystems. Their peculiarity is due to the variety of morphological forms ability colonise various substrates. The establishment fundamental issues biotic organisation this group fungi, which considers both their specific features integration into general ecological patterns, necessary basis for...

The purpose of the research is to determine relationship between infestation Cryptosporidium parvum in calves that have regular contact with synanthropic reservoirs (rodents and birds) climatic zones Udmurtia. study distribution manifestations cryptosporidiosis was carried out among rodents (gray rat (Rattus norvegicus), house mouse (Mus musculus), common vole (Microtus arvalis), bank (Myodes g...

The aim of the presented investigation was to describe seasonal changes microbial community composition in situ different biocenoses on historical sandstone Northern Pergola Museum King John III’s Palace at Wilanow (Poland). biodiversity analyzed by application Illumina-based next-generation sequencing methods. metabarcoding analysis allowed for detecting lichenized fungi taxa with clear domina...

Global development of transportation dependent on internal combustion engines, involves major increases in the consumption fossil fuels obtained by extracting crude oil from depths means wells and refining it. In this context, protection environment groundwater quality is an increasingly difficult objective to maintain, requiring modern methods address possible negative effects environment. The...
