It is well known that the population structure of plants in permanent plots change from year to year. Species abundances probably shift with time due to both species biology and variation in environmental factors. The main purpose of the study has been to describe and analyse long-term variation in the abundance (coverage) of blister sedge Carex vesicaria and reed canary grass Phalaris arundinacea in relation to time and space after a permanent lowering of a lake water level and exposition of new areas for species colonization. The study area lies in outer edge of a freshwater fluvial delta in the northern part of the Myrkdalen lake (229 m a.s.l.) West Norway, which was exposed after a permanent 1.4 m lowering of the summer water level in 1987. A 40 m long transect with ten 0.5 m × 4 m plot was established on the lower parts of the exposed delta in 1987. Study plots were situated at mean heights between 13 and 92 cm above the new summer water level. Floristic composition of the plots was monitored and analysed from 1988 to 2020, a total of 19 times. The plants show major differences in establishment, growth, and long-time dynamics in the permanent plots. The coverage of C. vesicaria and P. arundinacea was highly variable over the study period. Variations in coverage were related to time using regression analyses. The trends were mostly best described by cubic functions. Both species showed relatively low coverages between 18 and 26 years after the lake water drawdown, but increased again over the last study periods. Maximum coverage of the species was in time gradually separated by elevation. C. vesicaria became dominant in plots less than ca. 50 cm above the mean summer water, and P. arundinacea reached higher coverage above that elevation. The study indicates that elevation, as a proxy for flooding duration, and not aboveground species competition was the main factor for this difference in distribution.

In this study, three polymer types of microplastics (MPs), polyethylene (PE), polystyrene (PS) and polypropylene (PP), were exposed for 60 days in Xincun Bay (Hainan, China), a long-term mariculture tropical lagoon. High-throughput sequencing and scanning electron microscopy (SEM) were used to investigate the succession of microbial community structure and function on MPs after 10, 30, and 60 days of exposure, respectively. The results showed that diversity indices for bacteria from MPs were higher than those for bacteria from seawater. Significant differences were observed in community structure and metabolic function between MPs and seawater. The microbial network structure on MPs was more complex and dispersed than that in seawater. No significant differences in bacterial community structure and metabolic function were observed among different types of MPs.The biofilm on PS was the thickest, and the network structure on PP was the most complex one. With increasing exposure time, the biofilm attached to the surface of MPs became thicker and microbial composition showed some differences.The analysis of potential degradation bacteria and pathogens with abundance above 0.01% showed that the abundance of several potential plastic biodegraders on MPs was higher than that in seawater, while no potential pathogen was found enriched on MPs.

Open pit coal mining is a global problem, because mines occupy large areas that completely change the relief, dramatically affect ecosystems, as a result of which they lose most of their functions, and a significant part of the fertile soil degrades and becomes unsuitable for agricultural activities. In the presented work, the initial stage of soil formation was studied, the parameters of the granulometric composition of uneven-aged rocks of Donbas mine dumps, their nutritional regime, and the species composition of soil algae were studied. Samples were taken from three different-aged rock dumps of the mines: "South-Donbaska - 3" (rock storage for 40 years); "South-Donbaska - 1" (storage of rock for 52 years), "Trudovska No5 - bis (storage of rock for more than 100 years). The agrochemical parameters of the rock were determined in the samples: pHwater, humus, nitrate nitrogen, mobile phosphorus, exchangeable potassium, particle size distribution. The determination of granulometric fractions of 0–20 cm layer of rock dumps of the mines shows, along with the age, a potential increase of the dump of fine fractions and a decrease in the fraction of stones from 83% in the dump of the South-Donbaska mine, and by 30 to 64.7% in the dump of the Trudovska No. 5-bis. The proportion of the clay fraction is not high in all dumps and it does not exceed 1%, but its appearance indicates the initial stage of a soil structure formation. Soil formation begins with the colonization of mineral rocks with soil algae. The species composition of soil algae, the quantitative accounting were determined by microscopy of a freshly selected soil sample and by cultural methods. Algae species were determined by determinants. In the rock dump, the structure of algal groups becomes more similar to, their structure in the background soils of the territory. The dominance of the representatives of Chlorophyta and Cyanophyta in the rock indicates the steppe process of soil formation. The data obtained contribute to the expansion of the ecological and biological understanding of the initial stages of the formation of soil cenoses.

The present study investigates the influence of seasonal dynamics on macrobenthic assemblages in four seasons of 2017-2018 from the central sector of Indian Sundarbans which is under the constant threat of climate change. Besides taxonomic analysis, a trait-based approach has also been applied to assess the change in their ecosystem functioning. The maximum species density (11675 ± 11883.31 ind. m−2) was observed during the spring season which declines considerably in the monsoon season (5875 ± 6224.08 ind. m−2). A total of 95 macrobenthic taxa were recorded from Sundarbans and they were dominated by families like Capitellidae, Donacidae, Magelonidae, Nereididae, Paraonidae and Spionidae. Overall, polychaetes have shown higher taxonomic and functional variation than other groups. Opportunistic polychaete species have shown a prominent compositional shift during post-monsoon seasons. Both the univariate and multivariate analyses have shown a significant relation between macrobenthic composition and environmental parameters. SIMPER has depicted that environmental parameters made the station 4 unique for several types of molluscs like Acteocina estriata, Stenothyra deltae and Meretrix meretrix during spring. Trait percentages also showed a seasonal succession pattern and among the trait categories, burrowers and deposit feeders dominated the estuary. A gradual increase in suspension feeders in spring has been noticed. RLQ approach with fourth-corner analysis was used to unravel the relationship between traits and environmental parameters. Hence, the present study provided a comprehensive idea about the species composition along with their trait categories from such a dynamic habitat. That could be the first stepping stone for a long term monitoring of macrobenthic assemblages from this largest delta on earth.

Family businesses play a crucial role in the Polish economy, making up around 36% of the entire SME sector. The development of family companies has been connected to various dilemma, concerning, among others, their continuity and succession. In Polish family-owned businesses, there has appeared a long-expected moment of handing over power to the upcoming generations, i.e. to the so-called Y generation that is now pursuing their university studies. The author of the article has presented the characteristics of ‘Y’ generation successors, with a special emphasis on their distinctive features, as well as backing statistical data. The main core of the paper includes a proposal of a university programme for future managers of family companies. The programme, consisting of 5 modules, revolves mainly around the specific and complex character of the succession process, information policy within the said process, developing managing successors’ managerial skills, with a particular emphasis on their enhancement, as well as informing about the organisational culture of family businesses and the formal and legal conditions of successions.

This study aims to investigate the role of CEO succession in family business and the effect on financial risk. Using a Generalized Least Square (GLS) regression analysis and unbalanced panel data of 48 family firms, the stagnation, agency perspectives, and signaling model of their behavior were tested. This study finds that CEO turnover is negatively associated with firm’s financial risk. Furthermore, CEO descendants are more risk averse than CEO founders, and older CEOs are also more risk averse than younger CEOs. In addition, CEOs with higher education are also more risk averse. This implies that the Indonesian family firms are conservative towards financial risk. In relation to the stagnation perspective, the decrease in financial risk of family firms in Indonesia will be premature to be concluded that it will be in a stagnant phase.

W artykule przedstawiono rolę sukcesji dyrektora generalnego w firmie rodzinnej i jej wpływu na ryzyko finansowe. Wykorzystując analizę regresji Uogólnionego Least Square (GLS) i dane niezrównoważonego panelu 48 firm rodzinnych, przetestowano stagnację, perspektywy agencyjne i model sygnalizacyjny ich zachowania. Badanie wykazało, że zmiana prezesa jest negatywnie związana z ryzykiem finansowym firmy. Ponadto potomkowie CEO są bardziej niechętni do ryzyka niż założyciele CEO, a starsi CEO są bardziej niechętni do ryzyka niż młodsi CEO. Ponadto prezesi z wyższym wykształceniem są również bardziej niechętni do podejmowania ryzyka. Oznacza to, że indonezyjskie firmy rodzinne były konserwatywne wobec ryzyka finansowego. W odniesieniu do perspektywy stagnacji zmniejszenie ryzyka finansowego firm rodzinnych w Indonezji będzie zbyt wcześnie, aby stwierdzić, że wystąpi faza stagnacji.

The model reclamation process of the studied fly ash deposits has been started in 2003 by formation of five different experimental surface layers containing fly ash and organic matter in various combinations. Then, grass mixture was sown on these surface layers. In 2015, selected properties of plant communities growing on different variants of surface layers applied in the reclamation process were assessed. It was assumed that the type of mineral and organic substrates used in the process and their quality were the main factors affecting the long term plant diversity present on different variants of restored surfaces. The aim of this analysis was the assessment of the effectiveness of ash waste reclamation (carried out on five different types of the surface layer) after 12 years since its initiation. The long term results of the reclamation process showed that the applied surface layers allowed for an effective reclamation of ashes since all variants of experimental surfaces were totally covered by dense vegetation. The predominance of plant species from ruderal and segetal habitats indicated that the soil of the experimental habitats was fertile with neutral and slightly alkaline pH, and texture of sandy loams. The experimental surface layers with a texture of sand of favourable C:N ratio, neutral or slightly alkaline did not limit the plant development. The use of organic waste markedly contributed to the floristic diversity of the spontaneously developed vegetation. Coniferous bark used in some experimental variants had a marked effect on their floristic distinctiveness due to the presence of species preferring habitats of lower pH values.

This study focuses on the taxonomy of epiphytic diatoms in the area of invasive macroalgae from the genus Caulerpa. Caulerpa species are characterized by the presence of secondary metabolites, such as caulerpenyne (CYN), the main function of which is a chemical defense mechanism against herbivores and epiphytes. Epiphytic diatoms were studied on fronds of Caulerpa taxifolia (“killer seaweed”) and, for comparison, on autochthonous macroalgae Padina sp. and Halimeda tuna at the eastern Adriatic Sea coast (Island of Hvar) in the summer and autumn of 2010. The qualitative analysis was performed with the use of light and scanning electron microscopy. The Shannon–Wiener Diversity Index determined for Caulerpa taxifolia showed a wide range of values (3.11–4.88), with a maximum in August and a minimum in October. While the number of taxa on Caulerpa taxifolia fronds increased from June (41) to August (88), it declined in autumn due to the high relative abundance of Cocconeis caulerpacola, which is a diatom typical for Caulerpa. On the other hand, the largest number of taxa on Padina sp. was observed in September (82). The detailed composition of epiphytic diatoms and seasonal dynamics in the area affected by the invasive macroalga Caulerpa taxifolia have been determined for the first time.

In this paper, the analysis of the vegetation growing on the waste dump Siechnice was carried out. On the basis of phytosociological relevès, the plant species were determined. It was shown that vegetation identified on the waste dump is similar to the plants growing around this area. What is more, ecological succession of Urticaceae was observed, which proves succession of plants preferring alkaline soils. In addition, the ecotoxicological tests did not show the contamination impact of soil samples. We recorded only a slight inhibition of growth of A. sativa (in the shoot length in lower part of dump).

Post-industrial sites form a unique phenomenon in the landscape. They enable us to study the human-altered succession of communities. Regarding this, we studied an ant community in three types of habitats – reclamation and spontaneous succession in an ore basin together with unaltered surroundings in the Czech Republic. More than 30 years after being abandoned, the site with spontaneous succession was more species rich than the reclaimed one. Moreover, spontaneous succession created a habitat that was more similar regarding ant diversity to the unaltered surrounding environment than that after traditional reclamation. Ants dependent on tree vegetation were rather rare in both the reclaimed and spontaneous succession parts of the ore basin compared to the surrounding landscape. The relative abundance of socially parasitic ants increases in a gradient from the reclaimed basin, through the basin with spontaneous succession to the unaltered surroundings. Our study highlighted the fact that the formation of ant communities at post-industrial sites is clearly more complicated than for other arthropods, including related aculeate hymenopterans. The potential of both reclaimed and spontaneous succession basins for harbouring endangered species appeared to be lower for ants than for other taxa indicated by recent studies.

The problem of succession has been more and more frequent in investigations concerning the future of agricultural farms in Poland. The reducing number of inhabitants, ageing society and a declining number of new births are only some of the factors which highlight this problem. The focus of the study was on the agricultural farms in the case of accidental events such as death or serious illness that makes it impossible for the owner to make representations and sign on behalf of the business solely. These problems are critical from the standpoint of ensuring the continuous operation of the farm. The study was carried out with using a questionnaire and analysis of the independence of the Chi-square test (χ2). Most of the farmers studied think about what would happen in the case of their permanent loss of ability to manage the farm, and especially in the case of their sudden death. The opportunities for presence of other negative events such as serious illnesses seem to be neglected by those who manage agricultural farms. This is likely to be due to the psychological reluctance to think and prepare for such difficult scenarios. The study also demonstrated the lack of correlation between the size of agricultural farm and securing farmers against the accidental events. A moderate relationship was observed only at the level of general planning of the future of the agricultural farm. One of the popular forms among the owners of agricultural farms was establishment of a kind of mortis causa plenipotentiary.

The aim of this paper was to indicate prerequisites for successful succession in a family company from the successor’s point of view. The author presented the methods used to assess the conditions of the succession process with the use of observations and an individual semi-structured interview. Particular emphasis was placed on the influence of being brought-up in an entrepreneurial family on the further development of the successor’s professional career. Special consideration was given to finding out why a successor chose a particular area of education and what the parents’ influence on was shaping his/her entrepreneurial attitudes. The author underlined the role of emotional intelligence, as the latter is a part of the successor’s competencies. In this field, the author defined the competencies that are of crucial importance for the given process. The author enumerated factors affecting the succession process to the greatest extent, and the key role of the senior member in ensuring the continuity of the family company was also shown. Furthermore, the paper indicated the course of the succession process in the family business, as the former should be a comprehensive, long-term, and meticulously planned process in which (apart from the formal requirements and competencies) one should take into consideration family values, rules of the behavior and traditions of the company.

The investigations of the effect of different habitat conditions on the composition of the seed rain and seedling pool were conducted in the years 2014 and 2015 in abandoned patches of Molinion caeruleae dominated by small-stature meadow taxa (patch I), tall-growing grasses (patch II), as well as shrubs and trees (patch III). Observations showed that along the successional gradient the seed rain and seedling pool diminishes. The prevalence of perennials and native taxa in the seed rain and seedling pool occurred in all the study sites. Moreover, in the propagule and seedling pools of all the patches hemicryptophytes and meadow taxa prevailed but their number decreased in successional sites. Also, the abundance of ruderal and grassland taxa decreased gradually, at expense of number of forest species. Zoochorous species prevailed in the seed rain and seedling pool of all patches. Number of hydrohorous species decreased in successional patches, while the abundance of species with other dispersal modes were similar. Irrespective of patch character, the species producing propagules with medium size dominated in the seed rain and seedling pools, whereas a significant decrease of number of small-seeded species was noticed only in the seedling pool. Despite the diminishing of the seed rain and seedling pool along the successional gradient, the gap creation might be a very effective way of active protection of Molinion caeruleae meadows. However, the gap colonisation requires permanent monitoring to avoid further spreading of undesired taxa.

W pracy na podstawie wymiarów, jakości i żywotności drzew oraz właściwości gleb oceniono, że realizowana rekultywacja leśna na terenach pogórniczych kopalni Osiek przebiega na ogół prawidłowo. Zbiorowiska drzewiaste z sukcesji wykorzystywane w proces rekultywacji charakteryzowały się dużym bogactwem gatunkowym oraz dobrą żywotnością. Skażenie siarką gleby wystąpiło tylko w nielicznych punktach. Pewien niepokój wzbudza natomiast niska przeżywalność 3-letnich upraw wprowadzonych na badany teren.

EN

The studies on the assessment of forest reclamation on post-mining areas of the Osiek Sulpfur Mine were carried out on 24 experimental plots (10 × 10 m), sixteen of which were located in the area where the full cycle of reclamation treatments was conducted, whereas eight of them were the lands where the existing secondary biocenoses were used. The ongoing forest reclamation on the post-mining lands of the "Osiek" Sulphur Mine was assessed as generally appropriate. The trees that entered the area under the evaluation through succession displayed lower quality, though considerably higher viability when compared with those introduced in the scope of reclamation treatments. While the initial soils in the areas subjected to the full cycle of reclamation treatments were characterised by more favourable granulation, higher pH value and higher carbonate con-tent in relation to the soils where the biocenoses formed through succession were left.
