It is known that plant invasions are of major concern as they result in loss of biodiversity and alterations in ecosystem processes and functions. Although numerous mechanisms have been postulated to find out the reasons behind plant invasiveness, the actual and precise mechanism is still obscure. Soil microbes are considered as one of the important determinants of plant growth and establishment....

The aim of the study was to determine the impact of the increase in the organic matter content in the bottom sediments on the benthic fauna structure. The research was carried out in a strongly rheolimnic the Włocławek Dam Reservoir (Poland). The samples were taken on eight dates from March 1988 to February 1989. The sampling sites were located at the following depths: 1 m, 2 m, 5 m, 8 m and 10 m...

The aim of the paper was to evaluate the structure of macrozoobenthos in acid, oligotrophic Jasne Lake. The basic abiotic parameters of water and bottom sediments were also studied. The samples were taken on five dates: 25.11.1997 and 13.05., 01.07., 7.08. and 21.10. in 1998. The sampling sites were located in four clearly different zones of the lake bottom at depths: 5 m, 10 m, 15 m and 19 m. The...
