\nBarbara Pawlik-Skowro\u0144ska, Tadeusz Skowro\u0144ski
\nCyanobacteria (= Cvanophyta- blue-green algae) still play an important role in different biotopes of the whole biosphere. This review concerns interactions between these microorganisms and heavy metals – the common pollutants of aquatic environment. Cyanobacteria bind superficially and accumulate intracellularly both essential and toxic metals. In this way, they influence the partitioning of metals between different components of ecosystem, and the equilibrium concentration of metals in water. Under some specific environmental conditions (high pH) cyanobacteria can exist and grow in strongly heavy-metal polluted waters, although their metabolism is more sensitive to toxic metals than that of eukaryotic algae and fungi. Toxic impact of heavy metals on cyanobacteria comprises inhibition of photosynthetic processes, changes of enzyme activities, inhibition of growth and metabolism, desintegration of cell structure etc. All these effects are a consequence of metal uptake. Cyanobacteria bind heavy meta Is in two phase process comprising surface sorption and intracellular, metabolism-dependent transport, Physico-chemical environmental factors (light conditions, temperature, pH, presence of other metal cations and anions, etc) influence the bioavailability and toxicity of heavy metals due to their influence on both phases of uptake process and chemical metal speciation. In aquatic environment, cyanobacteria as a component of seston, play an important role in biogeochemical metal cycling. They are also a significant source of organic compounds excreted or released during senescence into the water, which can change the heavy metal speciation and availability to living organisms.

\nGlony jako czynnik degradacji r\u00f3\u017cnych materia\u0142\u00f3w [Algae as a degradation factor of various materials]
\nKrzysztof Jan Krajewski
\nThe present knowledge in the field of algae impact on different materials is presented, as based both on the original study and literature search. Data are presented on the influence aerophytic algae on building materials and wood in particular. Results are also reported of studies concerning the effects of superficial occurrence of algae in water environment. The data collected suggest that, besides the lasting discolouring, algae exert negative influence upon studied materials, both in the water and land environment. The observed alteration of physical and mechanical properties of materials under question are of mainly superficial character but it is also possible, in the case of wood, that limited deep effects will occur. The mechanism of destruction the studied materials by algae cannot be considered fully explained. The quoted here research on the relationship between algae and their environment suggest that algae may influence in an active way on various substrates.

\nGrzyby mikroskopijne wyst\u0119puj\u0105ce w Arktyce i obszarach alpejskich [Microfungi in Arctic and alpine regions]
\nAndrzej Chlebicki
\nThis review is concerned with the strategies of survival under Arctic and alpine conditions and adaptation of fungi to the short Arctic and alpine summers. The arctic-alpine species show ecological and morphological adaptations as the simplification of life cycle, the formation of ascospores with thick, pigmented walls and gelatinous sheats which protect against DV-B radiation. The comparison of ascospores of dryadicolous fungi from Tatra Mts, Alps, Scandinavia and Spitsbergen shows increasing participation of species with pigmented ascospores towards North.

\nSkaningowy mikroskop elektronowy w badaniach karpologicznych [Scanning electron microscope in carpological studies]
\nJagna Karcz
\nThe structure of plant surfaces has been intensively studied under taxonomic and ecological aspects. During the last decade the application of scanning electron microscope has greatly increased our knowledge of plant surfaces. The SEM is a surface microscope and the subject under examination is the natural primary surface of a plant – the epiderm, which covers i. e. seeds and fruits. Structurally, epiderms are usually rather thick-walled and stable in a vacuum: this allows quick preparation for SEM examinations, without the need for complicated dehydration techniques. Epidermal characters of seeds and fruits are surprisingly little affected by the environmental conditions in which a plant grows: there is evidence for a strong genetic control over these characters. Their high structural diversity provides most valuable criteria for the classification between species and family level. The comprehensive bibliography of Brisson and Peterson [13] indicates the value of the SEM for the study of seeds and fruits. Surface characters may be grouped into four categories (Figs. 1,4): (1) cellular arrangement or cellular pattern, (2) Shape of cells (the „primary sculpture” of a surface), (3) Relief of outer cell walls (the „secondary sculpture” superimposed on the primary sculpture), caused mainly by cuticular striations and superficially visible wall inclusions and wall thickennings, (4) Epicuticular secretions (the „tertiary sculpture” superimposed on the secondary sculpture), i. e. mainly waxes and related substances. Micromorphological and ultrastructural data have contributed invaluable information to our understanding of the evolution and classification of seed plants and play an important role in the modem syntetic systems of Angiosperms (e.g. Dahlgren [18]).

\nRola proliny u ro\u015blin wy\u017cszych w warunkach stresu abiotycznego [Role of proline in higher plants under conditions of abiotic stress]
\nPiotr Karolewski
\nIn this review the influence of abiotic stress factors on the level of proline in different plant organs is discussed. This is very difficult because the content of proline is also depends on the influence of many interacting intrinsic (age and stage of developement) and external (temperature, humidity of air, water status, nutrition etc.) factors. Results of much research indicates that influences of abiotic factors, such as toxic gases and metals, salinity, drought, low and high temperature affect free proline in a similar fashion. It is characterized by three stages: an initial lack of significant changes, followed by a rapid increase, and finally a reduction in the level of this amino acid, depending on the dose of the acting stress factor. These changes have a similar course, irrespective of the sensitivity of the plants. This indicates that in the sphere of proline metabolism, we are dealing with a qualitatively identical mechanism of plant reactions, irrespective of the the type of stress factor and the degree of plant tolerance. However, more sensitive plants respond earlier, at lower concentrations or interactions of the stress factors than do more tolerant plants. The stages refered to above correspond respectively to: I) defence reactions, 2) unfavourable metabolic changes and 3) degradation processes leading in effect to the death of plants. The active participation of proline in the defence reactions of plants against the injurious effects of stress factors can take place only at relatively low levels of the stress factor, i.e. until the period of rapid increase in the level of this imino acid. On the other hand, excessive levels of free proline accumulation expresses the degree of stress already experienced.
