Though current conservation policy in Poland refl ects world trends and approaches to action, compliance with all of its assumptions would entail the Polish authorities remodelling both the system and the methods by which natural resources are managed. On the one hand this requires a change of approach to the management of natural resources from the traditional, purely nature-related one, to a more modern inter-disciplinary one that takes in social and economic conditioning. On the other hand, a system need to be put in place to allow these ideas to be introduced in practice. The work described here deals with the participation of different stakeholder groups in nature management, with this regarded as a method of increasing the latter’s effi ciency. The many examples (of good practice) presented by the author well illustrate the wisdom of the approach, which often seems to achieve success where it is attempted.

Biodiversity conservation cannot operate in Central Eastern European countries without a well-established monitoring system, that is dependent on the citizen scientists input. Here we analyse, based on a Polish case: (1) The contribution of NGOs to the national nature monitoring scheme and their collaboration with governmental and scientific institutions and (2) the motivation of citizen scientists to volunteer for NGOs’ monitoring activities. The study comprises a focus group interview, 30 in-depth interviews with coordinators, citizen scientists, experts and a 23 days long participant observation of a model NGO. We have assessed the monitoring input of NGOs as being a contributory factor influencing the biodiversity conservation effectiveness. The cooperation between governmental, scientific institutions and NGOs exists, but is dependent on national funding. Although NGOs highlight the lack of coherence in monitoring methodology, they are willing to join the biodiversity monitoring, especially at the European Ecological Network – Natura 2000 sites. On the other hand the trust concerning cooperation with citizen scientists is limited. However, despite this, they still turned out to be trustworthy partners. The most effective way to maintain cooperation with citizen scientists is to create a bond in a group and to provide them with the opportunity to develop their passion for nature. Our findings have shed light on the growing importance of citizen scientists in biodiversity governance, providing recommendations for development of the effective monitoring schemes based on the volunteer work of citizen scientists.
The study was performed on 45 bitches in different cycle phases that were divided into the following groups: anoestrus (I, n=15), heat (pro-oestrus (n=7) or estrous (n=8) (II, n=15) and metestrus (III, n=15). Moreover, all experimental dogs were grouped according to their age: younger than 5 years (Y, n=35) and older than 5 years (O, n=10). The endometrial status was evaluated using cytological, bacteriological and biopsy samples obtained after ovariohyster- ectomy.
The main uterine pathology diagnosed by biopsy was endometritis, since 40%–66% of bitches, independent of the experimental group, developed this condition. No significant differences were found among the cycle phase groups (p>0.05). By contrast, significant differences were found in the age groups; the prevalence of this pathology was higher in older bitches (p=0.0019). The general prevalence of cystic endometrial hyperplasia (CEH) and a normal endometrium (NE) was lower (6.7–26.7% vs 26.7–53.3%) in all groups, and no statistically significant differences were found between certain groups (p>0.05). The percentage of polymorphonuclear neutrophilic leukocytes (PMNs) in endometrial cytology was generally low (< 2%) and did not differ signifi- cantly among the experimental groups (p=0.142). In general, a low degree of correlation was found between the diagnostic results by endometrial cytology and biopsy (Kappa Coeffi- cient=0.046). Positive bacteriological findings were found in approximately 50% of the bitches, independent of the cycle phase and health status of the endometrium. No correlation was found between the bacteriological and histopathological findings (p=0.883).
In conclusion, uterine cytology is not a reliable diagnostic method to detect the subclinical inflammatory and degenerative uterine pathologies in cyclic bitches.
Prognozuje się, że zasoby wody słodkiej dostępne dla ludzkości zmniejszą się o 30 proc. w ciągu najbliższych 20 lat. Jak odwrócić degradację zasobów wody i zrównoważyć zapotrzebowanie ludzi na wodę z potencjałem hydrosfery?
Forecasts suggest that the freshwater resources available to our civilization will shrink by 30% in the coming two decades. How can we reverse the degradation of water resources and create a balance between the society’s demand for water and the capacity of the hydrosphere?
The aim of this paper was to test currently available on the market products for sealing anodic oxide coatings as well as to test the use of other alternative substances improving the sealing process. The ability to seal in 10 different solutions and the quality of the seal has been tested. The influence of the applied preparations on corrosion resistance and resistance to strongly alkaline environment was also investigated.
Based on the results obtained, satisfactory results were archived for the sample sealed in a IMN-OML (Institute of Non-Ferrous Metals in Gliwice, Light Metals Division) solution sealant and in solution of nickel acetate in a medium-temperature process. Sealing by means of nickel acetate solutions is economically justified, and its use allows the process temperature to be lowered. When it comes to resistance to alkalis, samples sealed in IMN-OML sealant are the best. Commercial solutions have also achieved positive results in all tests.
