As cities are developed in line with sustainable development, space needs to be efficiently utilized. A balance must be achieved between investment sites and naturally active areas in order to shape the urban environment. In the public city, green spaces represent an indisputable element and are essential. An urban greenery plan is an essential component of a city's economic development. In recent years, spatial planning has been gaining government attention, particularly green development. Responsible management of these spaces is essential. However, urban foliage management appears to be a challenge for local authorities. In a spatial development plan, new greenery may be created, destroyed green spaces should be renovated, or brownfields must be repurposed. The purpose of this paper is to present a coherent concept for reclaiming the estate in Krakow, focusing especially on landscaping the Riverside Park. The design will create a friendly space that can be used by residents for rest and meetings, as well as enhance aesthetics and quality of life. Parks and community gardens are listed as strategic components for equipping the city with public spaces for meetings and recreation as well as other activities.

W Polsce ilość odpadów poddanych recyklingowi organicznemu – kompostowaniu począwszy od roku 2015 wzrasta. Obserwuje się także rosnącą ilość selektywnie zbieranych odpadów komunalnych, w tym biodegradowalnych. Recykling organiczny bioodpadów daje możliwość odzyskania materii w formie kompostu lub stabilizatu, przy jednoczesnym zmniejszeniu ilości odpadów kierowanych na składowiska. Kompost przeznaczony na nawóz musi spełnić określone wymagania jakościowe zgodnie z Ustawą o nawozach i nawożeniu. Otrzymany nawóz znajduje szerokie zastosowanie m.in., jako: środek wspomagający uprawę roślin, podłoże w rekultywacji terenów zdegradowanych, dodatek do pasz i ściółek.

After thorough field explorations in these areas from 2012 to 2020 in different seasons, 38 species of Impatiens are recorded, in which 6 species are endemic to Western Ghats and 26 species are endemic to southern Western Ghats of India. Horticultural potential of 18 endemic species of balsam is also discussed.

The observations, lasting above one year, have concerned particular plant species and plant communities on two selected savanna plots burned earlier, situated near Lusaka, and additionally some other localities. After the opening remarks, some information about fire’s influence on vegetation is given, with a quotation of papers connected with the area of investigations, as well as the author’s and Jan Kornaś’s publications. Those texts are followed by a short description of the geographical conditions in the region taken into account, of the studied plots, and information about the methods of investigations. Subsequently, there is a list of noticed species, with short descriptions and some pictures. Phytosociological data are presented in tables. The following chapters contain the joint characteristic of the studied vegetation: data about its floristic composition, phenology, and morphology of species. The Raunkiaer’s plant classification is considered here; afterward data on the water content in some roots and rhizomes are presented. The next chapter contains the description of common features of vegetation on the studied plots. Thereafter may be found information about the pyrophytic plant species noticed elsewhere in Zambia. In the discussion publications supplementing the author’s study are mentioned. Further, more detailed descriptions of the features of fire, its occurrence in nature, distribution, and structure of savannas are included. Plant regeneration on the burned plots, the usefulness of Raunkiaer’s classification in the tropics, and problems of evolution of pyrophytes are presented. There is also some evidence of phytosociological studies in Africa and proposals for the establishment of a new association Hyparrhenio-Gardenietum. In the end, some conceptions concerning the rational use of fire, particularly in nature conservation, are mentioned, as well as arguments for the protection of pyrophytic species.

Jerusalem artichoke could be used as a source of renewable energy in the meaning of biomass combustion or liquid fuels production. The presented study concerned on the impact of JA plantation for biomass combustion on plant diversity. The spontaneous vegetation of JA crops studied on the basis of phytosociological methods consisted of varied groups of species that contain weeds (32%), meadow (29%), and ruderal (13%) species. Most of the species occurred sporadically (55%) with low frequency. Most of the plants accompanying JA cultivation were perennial, mainly hemicryptophytes (51%) with a smaller number of geophytes (17%). Therophytes constituted 25% of spontaneous flora of JA crops. It can be proposed the group of generalist energy crop weeds with Convolvulus arvensis, Elymus repens, Equisetum arvense, Ranunculus repens, and Rumex obtusifolius.

Macroalgae have been found to produce active allelochemicals that inhibit of growth other organisms that compete with them for light and space. However, their allelopathic activity on Baltic cyanobacteria is still insufficiently recognised. Therefore, this study aimed to demonstrate the allelopathic effects of Baltic macroalga thallus (Ulva intestinalis) on the growth and photosynthetic activity of three bloom-forming cyanobacteria: Aphanizomenon sp., Nodularia spumigena, and Nostoc sp. This study investigated the cell count of the analysed cyanobacteria (N 105 mL-1), the maximum quantum yield of the second photosystem (PSII) in the dark (Fv/Fm), and the real quantum yield of PSII in the light (ΦPSII) (in the control and the experiments). After 7 days of exposure, the following were added: 0.01, 0.05, and 0.1 g mL-1 of U. intestinalis fresh thallus. It was found that thallus obtained from U. intestinalis had no statistically significant effect on the number of cells of the cyanobacterium Aphanizomenon sp. (at 0.05 and 0.1 g mL-1) and Nostoc sp. (at concentrations of 0.01 and 0.05 g mL−1). On the other hand, it was examined a stimulating effect of 0.01 g mL-1 of the fresh thallus on the number of Aphanizomenon sp. cells which constituted 168%, relative to the control. It was shown that the fresh thallus addition resulted in a decrease in the number of N. spumigena cells (45%, 27%, and 46% after addition of 0.01, 0.05, and 0.1 g wet weight mL−1 of fresh thallus, respectively). In experiments with Nostoc sp., the addition of U. intestinalis thallus has been a negative effect on cyanobacterial growth at 0.1 g mL−1 and constituted 97% of control. It was also found, that U. intestinalis had no allelopathic effect on fluorescence parameters of N. spumigena. All tested concentrations of thallus U. intestinalis (0.01, 0.05, and 0.1 g wet weight mL-1) stimulated the values of Fv/Fm or ΦPSII of cyanobacteria Aphanizomenon sp. and Nostoc sp. compared to the control. These studies help define the role of U. intestinalis allelopathy as a biological factor in the distribution of bloom-forming cyanobacteria in the coastal Baltic Sea region.
人们发现，大型藻类能产生有效的化感物质，抑制与它们竞争光和空间的其他生物的生长。然而，它们对波罗的海蓝藻的化感作用仍未得到充分认识。因此，本研究旨在证明波罗的海大藻(Ulva ninteinalis)对三种形成水华的蓝藻的生长和光合活性的化感作用:本研究研究了所分析蓝藻的细胞计数(n105 mL-1)，第二光系统(PSII)在黑暗中的最大量子产量(Fv/Fm)，以及PSII在光照下的实际量子产量(ΦPSII)(对照和实验)。暴露7 d后，分别添加0.01、0.05和0.1 g mL-1的新鲜菌体。结果表明，大肠杆菌菌体对蓝细菌(0.05和0.1 g mL-1)和Nostoc sp.(0.01和0.05 g mL-1)的细胞数量无显著影响。另一方面，0.01 g mL-1的新鲜菌体对Aphanizomenon的细胞数量有刺激作用，细胞数量为对照的168%。结果表明，鲜菌体添加量分别为0.01、0.05和0.1 g湿重mL−1后，spumigena细胞数量减少了45%、27%和46%。在Nostoc sp.的实验中，添加0.1 g mL−1的大肠杆菌对蓝藻的生长有负面影响，占对照的97%。同时还发现，肠芽孢杆菌对棘球蚴的荧光参数没有化感作用。与对照相比，所有测试浓度(0.01、0.05和0.1 g湿重mL-1)均刺激了蓝细菌的Fv/Fm值和Nostoc sp. ΦPSII。这些研究有助于确定肠梭菌化感作用在波罗的海沿岸地区形成水华的蓝藻分布中的生物学因素。
