Continuous-flow microwave heating has potential in aseptic processing of various food products, including purees from sweetpotatoes and other vegetables. Establishing the feasibility of a new processing technology for achieving commercial sterility requires evaluating microbial inactivation. This study aimed to assess the feasibility of using commercially available plastic pouches of bioindicat...

Solitary bees (Hymenoptera: Apoidea) are endangered by extinction. Furthermore they are highly suited for nature conservancy indication purposes. Nevertheless their appearence in development and ecological planning tasks is quite seldom due to their diicult classii-cation. Our approach to classiication of solitary bees is based on two ideas: (1) to use only the veining of the wings for discrimi...

One of the ecological functions green open space (RTH) is to accommodate biodiversity in urban areas by providing a habitat for wild plants and animals. Pollution, urbanization, various other environmental pressures make spaces more susceptible disturbances, both natural due human activities, which can affect existence within them, including butterflies, have specificity sensitivity certain con...

Ecological patterns and processes are characteristically scale dependent, and research findings often cannot be translated easily from one scale to another. Conservation biology is challenged by a lack of congruence between the spatial scales of ecological research (typically involving small plots) and land management (typically involving whole landscapes). Here, I discuss spatial scaling issue...

Human health often depends on environmental variables and is generally subject to widespread and comprehensive surveillance. Compared with other available measures of ecosystem health, human disease incidence may be one of the most useful and practical bioindicators for the often elusive gauge of ecologic well-being. We argue that many subtle ecosystem disruptions are often identified only as a...

overgrazing, via harvesting of forage species and decrease the other herbs, is of progressive factors in biodiversity destroying. in order to investigate the animal grazing impacts on changing of plant structure and diversity, we selected the comparison between this effect with exclosure area, and proving of the excluded area effects on plant diversity; two sites of kojour rangeland, mazandran ...

Protists include all eukaryotes except plants, fungi and animals. They are an essential, yet often forgotten, component of the soil microbiome. Method developments have now furthered our understanding of the real taxonomic and functional diversity of soil protists. They occupy key roles in microbial foodwebs as consumers of bacteria, fungi and other small eukaryotes. As parasites of plants, ani...

SHEPPARD L.J. 1996. How reproducible are the reactions of stress indicators for Sitka spruce treated with acid mist? Phyton (Horn, Austria) 36 (3): (23) (30). Results of previously published experiments based on open-top chambers and field exposure systems with seedlings, mature grafts and physiologically mature trees (<13m tall) of Sitka spruce exposed to pH 2.5 mist are discussed briefly for ...
