The two new concepts in bio-indicative research
The aim of the study was to present the proposals for the use of new methods in researches about bioindication. The Study provides proposals of the use of the intrapopulational variability of plants and animals as an index of the quality of the enviroment as well as the results of the research in the literature on the conditions of intrapopulational variability of plants and animals. Furthermore the study includes proposals to determine index of capturability and the analysis of the suitability of Simpson’s coeffcient (for determining the biodiversity) and the coefcient of the effectivity of community – WEZ. The Author calls for a wider application of statistical methods in ecological researches. The study shows that there is a link between intrapopulational variability of plants and animals and the quality of their environments. The survey indicates a better usage of the coeffcient of the effectivity of community – WEZ than the Simpson’s coeffcient.
The tree stumps as a wintering site for some amphibians species
Amphibian complex life-story is derived as a main factor of their diffculty in regards of the protection. Well known from the spring migration and road mortality data have still some mysterys. One of them is how they choose and use wintering site. In this study we were trying to get an anwser on a question if new created hibernation site were use by amphibians and
which direction they choose during spring migration. We were also taking a data on the weather inﬂuence of the amphibian activity. We were set at about 200 meters of the drift fence around tree stapms layed on the 0.38 hectares area. Drift fences was daily checked in the period of 12 March to 08 May, usually 2–3 times per day. Totally 637 specimens were caught, belonged to 9 species. The most numerous species was common toad and the least numerous crested newt. Some of the
specimens were already in amplexus. Since few years the study area is under ongoing monitoring research and active protection in regards of the amphibians. In our research we have found that amphibians are gladly settle new created structures within their home range.
