16S rRNA sequences used to identification of bacterial DNA isolated from various materials
The aim of this study was the genetic analysis of two different material. The whole DNA was isolated from the air filter, located in Integrated Environmental Monitoring Station on Swiety Krzyz in the Swietokrzyskie Mountains. The second sample of whole DNA was obtained from sludge. Total DNA was extracted by two method – temperature
isolation and column isolation kit. Genetic analysis revealed presence only Eubacteria. The confirmation of the presence of Archaeacan be possible during further optimization of the used techniques. Presented results confirmed that air filters and sludge are the useful materials to isolate bacterial DNA to identification and to look for microorganisms which could possess some unique factors for adapt to environment. Air filters or sludge can be use
to metagenomic analysis of microorganisms present in different environment, especially to the identification of uncultured bacteria from environment.

The most important toxic elements of animal vemons
A lot of animal venoms is a complex mixture of structurally complicated compounds. Detailed data on the composition of the venoms, the chemical structure of components and their mechanisms of action allow for effective medical treatment in cases of intoxication. The study of toxins form biochemical and biophysical standpoint also allows characterization of receptors in cells and tissues (Ravdin, Darwin, 1979; Bradley et al., 2001; Hille, 2001, Smith et al., 2004). Toxins act in an antagonistic manner with respect to the endogenous physiological controls, thus disturbing the operation of the system, organ or the whole organism. The high specificity of toxin action manifests itself in many cases with the competitive nature of their antagonism towards endogenous compounds (mediators).

Ecological awareness of local societies. Expectations and the reality
Human became to be a source of imbalance in natural environment, as well as the recipient of many dangerous results of this phenomenon. An opportunity to make this situation better is the environmental education of society, compatible with the principles of sustainable development. Nowadays it is coming to the end of the Decade of Education for Sustainable Development 2005–2014. It is a global project, which was announced because of absence of sufficient effects assumed in the Sustainable Development Strategy in 1992 at the Earth Summit in Rio de Janeiro. The aim of sustainable development is to take over all the citizens of Poland to educate them at ecology. The article presents the results of research focused on attitudes and behavior of the local community of Plock, which is considered as one of the most aware of the natural environment in Poland. Research conducted by the author indicated not enough level of ecological awareness of local society, the teachers as well (Tuszyńska, 2013). It has negative impact on forming ecological friendly values and attitudes among students. Assuming that the knowledge gained in the youngest age becomes the foundation for the development of citizenship attitudes, it does not predict
good attitudes of society to natural environment.

Land development of the district of Sitkówka-Nowiny with a particular emphasis on the eia of the implemented investments which can have an impact on the elements of the environment in the years 2013–2016
Development of the land, which is a limited good, brings together many social, economic and cultural aspects which are a specific link, based on specific relationships and dependences taking place between them. Development of the district of Sitkówka-Nowiny is a model to follow, starting from a perfect use of the area, through the care of the development of that area. Harmony accompanying the development, supported with the logistics of made decisions, forward-looking orientation as well as the number of awards received by the district, show the recipe for the difficult economic situation in which the country today is. The implemented investments, which were carried out in the district, have been analyzed paying special attention to their impact on the environment.

Convulation evaluation of the place in the context of globalization processes
The article presents place evaluation of the convolution in the context of the globalization processes. The subject matters of place and its evaluation is of some importance as the key meaning tool in the humanistic geography. There are many processes, phenomena and trends distinguished that transform the surrounding us places, moreover, their straightforward relationship with the processes of globalization. It is stated that the main processes influencing the place are the following: the development of informational and communicational society, changing the mass society for the individualistic society, unification, consumptions, profit maximization and the creation of the virtual reality. The modern globalization can be perceived as the neoliberal political project (conspiracy) aiming at the relocation of the capital through the expropriation and appropriation of space, places and the capital at the expense of the majority of the population.

Variation inside the population of animals and plants as an indicator of the quality of their environments
Based on numerous field observations of Dendrominus piniL. caterpillars, a hypothesis had been formulated that in principle deterioration of living conditions causes an increase in intrapopulational variability of organisms.
The study aims at testing this hypothesis. Accordingly, measurements of the length of beetles Geotrupes stercorosusSc., their ecological and geographical populations and hights of pine seedlings of Pinus silvestrisL. had been performed in different forest site types of Poland.The results obtained confirm the hypothesis presented. The authors call for continuation of similar studies as they can yield results useful for environmental monitoring, as well as for certain aspects of silviculture.
