When incubated alone for 7 days with the fungus Cunninghamella echinulata, tranylcypromine was extensively metabolized. As observed in mammalian systems, N-acetyltranylcypromine was the major metabolite recovered along with lesser amounts of 4-hydroxytranylcypromine, as its N,O-diacetyl derivative. The rate and extent of tranylcypromine biotransformation was affected by whether incubation was on either 30° or flat brackets with a gyratory shaker. There is a strong association between the rate of biotransformation and the utilization of glucose, formation of ammonia, and pH. The slowest rates of biotransformation and metabolic response were observed with the large fungal pellets formed during incubation on flat brackets. These findings raise the possibility that, as in mammalian systems, fungal metabolism of xenobiotics can be affected by nutrient and environmental conditions. Key words: Cunninghamella echinulata, tranylcypromine, biotransformation, toxicity model.

Regional characteristics and diversity of Podiliya environmental conditions are considered, and there is shown that they were favorable to the settlement processes and performed multiple functions at all stages of history, one of which is the ability to use environmental conditions diversity as a source of physical and spiritual recovery. Special attention is given to the Podiliya landscapes formation, as one of the attraction factors. Key words: environmental conditions, landscape, tourism, recreation, region, forest-steppe.

Three spring and two fall crops of greenhouse tomato (Lycopersicon esculentum L. Mill; various cultivars) grown in "Harrow" peat bags were irrigated 1, 4, 8 or 16 times daily. All plants received the same volume of fertilizer solution which varied with time from 0.2 to 1.0 L plant−1 d−1 according to crop and environmental conditions. The results showed little or no effect of irrigation frequency on early or total yield, number of grade no. 1 fruit, or fruit size. Key words: Lycopersicon esculentum, marketable yield

The aim of the research was to check whether there is a relationship between the perception of the workplace by the employee as attractive and the level of job satisfaction experienced by him/her. These analyzes are part of the search for environmental conditions of job satisfaction. The study group consisted of 100 office employees were asked to complete three questionnaires: Job Description Questionnaire by Neuberger and Allerbeck, Job Affect Scale by Brief, Burke, George, Robinson and Webster, and authors’ tool to measure the physical assessment of attractiveness the workplace. The results obtained confirm that the attractiveness of the workplace together with the perception of individual elements of space arrangement are related to job satisfaction, both in the emotional and cognitive dimensions. Thus, the results can be a premise to be used by the employer in the process of building an employer branding as inside-out as well as outside-in. Key words: workplace attractiveness, job satisfaction

The article analyzes the agro-ecological situation and problems of soil use in Lviv region. It is established that the conduct of agriculture is often not the landscape and environmental conditions of the area and agro-ecological conditions of cultivation of agricultural crops. In soils have become widespread degradation processes, such as water and wind erosion, acidification, dehumidification, the depletion of elements of the other power plants. The measures of rational use and protection of soils are proposed. Key words: Lviv region, soil, agro-ecological state of, degradation, soil protection.

We propose that the optimum habitat of the percid fishes Perca flavescens, P. fluviatilis, Stizostedton vitreum vitreum, and S. lucioperca in lakes may be defined by the littoral and sublittoral environmental conditions equivalent to those in large, temperate rivers. Analogous habitat conditions include sand or gravel substrate, low current velocity, reduced light penetration (Stizostedion spp. only), temperatures optimal for growth and reproduction, and well-oxygenated spawning substrates. The species' evolutionary origins and reproductive patterns also reflect their riverine ancestral habitat. Evidence in support of the hypothesis is derived from the diversity of papers contributed to the PERCIS Symposium. Key words: Percidae, habitat, theory, Perca, Stizostedion

The importance of microrelief in relation to mass loss was studied in a Minnesota ombrotrophic forested peatland. Litter and paper strips placed in hummocks for 1 yr lost significantly more mass (two and three times, respectively) than similar material placed in hollows. Less favorable environmental conditions for decomposition, especially lower temperature, reduced decomposition in the hollows. Key words: Peatlands, ombrotrophic, decomposition, Histosols

This study investigated the effects of parity, prior experience, and environmental conditions on the incidence of savaging on seven commercial farms. Results indicated that 3.40% of gilts and 1.22% of sows killed one or more piglets (P < 0.05). Fourteen percent of sows that savaged as gilts also savaged during their second farrowing, compared to 0.8% of sows that had not reviously savaged. The incidence of savaging was similar among gilts during the first (all gilt herd) and second (gilt/sow herd) farrowing cycles. Key words: Savaging, gilts, sows, pigs, maternal behaviour

Abstract Zooplankton community composition, biomass and metabolism can vary drastically over space and time in subtropical estuaries. Changing environmental conditions can affect communities differently, depending on the characteristics of the species involved. In the present study, we compared the rates of oxygen consumption of the dominant zooplankton taxa living in permanently open and in temporally open/closed estuaries. The metabolic response was tested at four temperatures experienced by the animals in their natural environment. Zooplankton from the temporally open/closed estuary showed low activation energies and low rate of metabolism at the highest temperature tested. Animals from the permanently open estuary had higher respiration rates at increased temperatures than those from the open/closed counterpart, with one taxon showing a particularly strong response to temperature increase. Results suggest that the metabolism of zooplankton in subtropical estuaries can be influenced by the environmental conditions experienced and those characteristics need to be accounted for in the development of bioenergetics budgets of species and ecosystems.
