The aim of the study was to determine the extent to which created and functioning beaver dams contribute to increasing water retention in the Łąki Soleckie facility (Mała River valley). Changes in the plant cover of meadow habitats within the range of beaver dams were also determined. During the growing periods in 2020-2022, measurements of the periodic levels and water retention of the Mała River and the adjacent ditches (R-27, R-29) were closely related to the activity of beavers and precipitation. The maximum volume of water retained in the Mała riverbed in 2020-2022 was 1,300, 1,700, and 1,200 m3 ; the maximum retention of the R-29 ditch was 270, 210, and 200 m3, respectively. In 2021-2022, the R-27 ditch collected the most water - 270 m3 and 250 m3. Starting from June 2022, due to beaver dams D2 and D3, the water level in the river and water retention have stabilised at a high level, despite slight rainfall. The activity of beavers contributed to the transformation of communities of wet habitats located on organic soils (Calthion) into communities of periodically wet habitats (Caricetum gracilis). In places where natural habitat 6510 occurs, the coverage of species of the Festuca genus has increased, and the value of the biodiversity index has increased by an average of 9%. High stability in the community of expansive species (Deschampsia caespitosa and Veronica longifolia) and their increasing cover may make it difficult to maintain the proper condition of natural habitat 6510.

Gdyby zrobić ankietę wśród Polaków, czy lubią przyrodę, to pewnie znaczna większość z nich na to pytanie odpowiedziałaby: „zdecydowanie tak”. To cieszy, ale i nie dziwi. Przecież ulubione cele naszych weekendowych wypadów to jeziora, rzeki, lasy i góry. Tak odpoczywamy i regenerujemy siły. Miasta i ogólnie tereny zurbanizowane, gdzie przyrody jest niewiele, powodują u nas uczucie zmęczenia, przygnębienia, a nawet wywołują stany depresyjne. Jednak okazuje się, że przyrodę lubimy wybiórczo.

Tychy, Poznań, Kętrzyn i Ciechanowiec to kilka przykładów miast, w których sady miejskie już są – jeszcze małe, ale ich istnienie pokazuje, że miasta są zainteresowane takimi układami zieleni. To doskonałe miejsca służące ochronie bioróżnorodności i edukacji. Jednak, jak wszystkie inne ekorozwiązania, wymagają specjalistycznego traktowania. Tak łatwo o posądzenie o greenwashing – lepiej tego unikać.

Lasy mieszane i liściaste, zwłaszcza niebędące lasami gospodarczymi, charakteryzują się szczególnie różnorodnymi siedliskami, stanowiącymi miejsce życia licznych gatunków grzybów, roślin i zwierząt. Różnorodność siedlisk leśnych zwiększa tzw. martwe drewno, czyli uschnięte drzewa i krzewy, stojące fragmenty pni, leżące kłody, gałęzie i opadłe liście. Warto mu się przyjrzeć, także w miastach, np. w kontekście wpływu tzw. czwartej przyrody na zachowanie bioróżnorodności.

Green walls, along with green roofs, parks, and vertical gardens, belong to the green infrastructure of cities, which will encompass the majority of humanity in the coming decades. Green infrastructure benefits both urban residents and nature in the urban landscape, although there is no scientific consensus on the extent to which green walls, especially green facades, impact biodiversity in cities. This study examined the influence of green facades on the richness of mammals, birds, and invertebrates, considering the species and age of the plants comprising the green facade in a medium-sized city located in southwestern Poland. It was found that the implementation of green facades significantly enhances species’ biodiversity compared to non-vegetated walls. Four synanthropic bird species were nesting on green facades: Eurasian collared dove (Streptopelia decaocto), blackbird (Turdus merula), house sparrow (Passer domesticus) and woodpigeon (Columba palumbus). For the beech marten (Martes foina), the green facades are a hunting ground for birds and their eggs. This simple and effective method of creating green walls provides benefits to local wildlife by creating habitats, shelter, and foraging opportunities for selected species. However, it is difficult to determine whether green facades contribute to the formation of ecological corridors in urban environments. The study also examined the social aspect related to the establishment and maintenance of green facades on the surveyed buildings.

A study was conducted on changes in the abundance and diversity of floristic composition in baulks and cultivated agrocenoses in the area of the village of Nowokornino, located on the outskirts of the Białowieża Forest. Within the geodesic area of the village, which covers approximately 1,100 ha, agricultural crops are grown under three farming systems: conventional farming, integrated farming and organic farming. In the study area, there are unique marginal ecosystems in the form of mid-field baulks on which various weed species of ecological importance occur. Three study plots were designated on the baulks, and three plots on field crops Floristic surveys were carried out in 2016, 2020 and 2022. The cover of individual species was estimated according to the 7-level Braun-Blanquette scale. A total of 91 plant species belonging to 6 phytosociological groups were found, with the Stellarietea mediae group having the highest species richness. The significance of differences in floristic richness between study and control plots was tested by one-way analysis of variance (ANOVA). Statistical analysis showed that the factors differentiating the floristic composition on the baulks were their location within the cultivated agrocenoses, natural soil abundance and interaction with fertiliser factors. The highest species abundance of plants defined as weeds, occurred in fields under the integrated farming system (58 species), the lowest in fields under the conventional system (39 species). The vegetation of the baulks and adjacent arable fields was dominated by plants representing mainly three types of ecological strategies: C, R and C-R.

The East Java coast has biodiversity potential, including microalgae. Microalgae are primary producers for the aquatic ecosystem, whose distribution depends on water quality parameters and sub-habitat characteristics. The purpose of this study was to analyse and identify the microalgae, as well as environmental quality parameters based on sub-habitat characteristics in the northern part of the East Java coast, Indonesia. The research was conducted from March to June 2023. Sample sites were determined using purposive sampling techniques at nine sites located in Gresik, Lamongan, and Tuban coasts. Water samples were collected from various sub-habitats, including the water column, sediments, rocks, mangroves, artificial substrates, macroalgae, and water plants consisting of water hyacinth (Eichhornia crassipes) and Coontail (Ceratophyllum demersum). The obtained results depicted microalgae found were from Bacillariophyceae, Chlorophyceae, Chrysophyceae, Coscinodiscophyceae, Cyanophyceae, Dinophyceae, Trebouxiophyceae, and Zygnematophyceae. Bacillariophyceae dominated the community in all sites. The expected outcome of this study is to provide and complete the database of microalgae morphologically based on sub-habitat characteristics, particularly on the north coast of East Java, Indonesia.

An increase in demand for energy from renewable sources has increased the hectareage of crops grown for energy purposes. The impact of large-scale energy crop monocultures on soil biodiversity is poorly understood and requires long-term monitoring. Due to their specific lifestyle, Lumbricidae, known as “ecosystem engineers”, have found application in biomonitoring of the soil environment. This study aimed to evaluate the qualitative and quantitative structure of Lumbricidae in annual rapeseed (Brassica napus L.) and perennial willow (Salix viminalis L.) crops for energy purposes, with a permanent grassland as a control site. The research was conducted on the territory of the Podkarpackie Agricultural Advisory Center in Boguchwała (southeastern Poland). Earthworms were obtained by hand sorting soil blocks of 25×25×25 cm and a 0.4% formalin solution was used to extract individuals from deeper soil layers. There were no differences in the species composition of Lumbricidae between the analyzed crops. Five species of earthworms, Dendrodrilus rubidus tenius, Lumbricus rubelllus, Aporrectodea caliginosa, A. rosea, and L. terrestris, were found at each study site. Rapeseed had the lowest density (17.26 ± 9.16 ind•m-2) and biomass (5.93 ± 2.42 g•m-2) of Lumbricidae (p < 0.05). On sites with willow and permanent grassland, density and biomass of Lumbricidae were similar (69.15 ± 28.99 ind•m-2; 26.55 ± 9.67 g•m-2 and 54.04 ± 22.93 ind•m-2; 20.03 ± 7.99 g•m-2, respectively (p > 0.05). The study demonstrated the beneficial effect of perennial willow cultivation on the quantitative structure of earthworm communities. Only long-term biomonitoring will make it possible to determine the real impact of energy crops on invertebrate assemblages and their appropriate management to promote biodiversity.

Restoration of grassland habitats useful for wildlife is an intervention often carried out in various marginal environments (such as some mountainous areas) where agriculture and grassland management have undergone deep changes in recent decades. To assess some of these interventions, a study was conducted in an Apennine reserve in Central Italy, where some grassland areas recovered through different techniques were identified, represented by shrub clearing followed by sowing of a forage mixture and shrub clearing alone, which were compared with natural areas on which no interventions were carried out. Several parameters related to the botanical composition and quality of the recovered pastoral resources were analysed. In addition, in three different experimental sites, further in-depth investigations were carried out to assess the actual animal frequentation and the impact of the in-take of the wild animals present (mainly red deer) on the occurring vegetation. Results highlighted the importance of recovery interventions in these situations, the success of mechanical treatments (even if represented by clearing shrubs alone), and the real appreciation for the recovered areas by wildlife, whose utilisation on different vegetal species could be assessed, highlighting a diverse feeding behaviour for some taxa, compared to domestic animals.

Drought is a large-scale disturbance that affects freshwater ecosystems worldwide. This recurrent phenomenon in Morocco, has experienced severe episodes during the last decade and has caused water stress in several aquatic ecosystems including the Youssef Ben Tachafine dam. Indeed, the volume of this reservoir has experienced its lowest historical hydrological level (12%) during the study period. To study the effects of water stress on water quality and planktonic community structure, water samples were collected from January 2019 to December 2020 at nine depths. The physicochemical parameters of the water were measured in parallel with the qualitative and quantitative study of the phytoplankton and zooplankton communities. The results obtained show a low planktonic diversity with only 43 phytoplanktonic species and 27 zooplanktonic species. The phytoplankton showed an almost permanent predominance of Chlorophyceae (85%), dominated by Closterium pronum, followed by Diatomophyceae (9.5%), dominated by Cyclotella ocellata. Rotifers represent the most abundant zooplanktonic group during the study period with two dominant species (Keratella tecta and Polyarthra vulgaris). Statistical analysis of the data from this study, using R software, revealed a negative correlation between Cladoceran species, Copepods and the diatom Cyclotella ocellata on the one hand and the decrease in water level, temperature and enrichment of the environment in nutrients and phytoplanktonic biomass on the other. This study shows that the effect of the extreme drought, which the Youssef Ben Tachafine dam has experienced, has altered the diversity and structure of planktonic communities, which threatens the sustainability of ecological services of this ecosystem.

This investigation of the biodiversity of copepods was carried out in the Hilla River. From January 2021 to December 2021, monthly samples of water and copepods were taken at three different locations in the river for this investigation. Water’s temperature, turbidity, pH, salinity, dissolved oxygen, biological oxygen demand, total hardness, nitrate, and phosphate are some of the physical and chemical characteristics taken into account. A study was undertaken using biological indicators such the Shanon-Weiner index, Species Uniformity Index, and Species Richness Index. There were 24 copepod taxonomic units found. Copepoda had a maximum density of 1453 ind/m3 in April and a lowest density of 80 ind/m3 in February. The statistical study’ findings revealed a statistically significant positive association between density, all of pH, BOD5, Nitrate, and Phosphate, as well as a statistically significant negative correlation with each of dissolved oxygen and total hardness. The Shanon-Weiner index recorded its greatest value in May, 3.33 bits/ind, and its lowest value in December, 0.08 bits/ind. The greatest value of the Species Uniformity Index (E) was 0.99 in March, while the lowest values of 0.1 were reported in July. Species homogeneity index and each of Turbidity have a substantial negative association and a strong positive connection, respectively. The Species Richness Index reached its greatest point in April (6.13), while it reached its lowest point in January (1.46). According to the statistical study, there is a strong positive association between Index values and a strong negative correlation with overall hardness.

Sixty-eight brachiopod species are reported from the upper part of the Skały Formation at Miłoszów (Łysogóry Region of the Holy Cross Mts., central Poland) on the basis of over 2,200 specimens. The fauna is Early to early Middle Givetian in age (timorensis to rhenanus/varcus conodont zones) and thus predates the Middle Givetian Taghanic Bioevent. One new genus and three new species are described. Leiocyrtia Baliński gen. nov. (type species: Leiocyrtia rara Baliński gen. et sp. nov.; Spiriferida, Cyrtiidae) is characterised by a non-costate shell with prominent sulcus and fold and capillate microornament. Undispirifer sidoniae Halamski and Baliński sp. nov. is characterised by transverse shells and dense ribbing. Moravilla andreae Baliński and Halamski sp. nov. is characterised by relatively coarse radial capillate ornament and is the first representative of the genus outside the type species from the Givetian of Moravia. The most abundant species are: Spinulicosta cf. spinulicosta, Antirhynchonella linguiformis, Pentamerelloides davidsoni, Peratos beyrichi, Plectospira ferita, Spinatrypa wotanica (confirmed to belong to that genus and not to Spinatrypina), Ambothyris sp., and Echinocoelia dorsoplana. ‘Spirifer’ quadriplicatus Sandberger and Sandberger, 1856, a rare species known from Miłoszów and the Rhenish Massif, is an orthide and belongs to Teichertina. The relationship between Skenidioides polonicus and S. cretus, formerly understood as anagenesis, is re-interpreted as budding cladogenesis. Davidsonia septata is reported as an epizoan on rugosan corals, a relationship never previously observed in representatives of that genus. Brachiopods represent different palaeoecological groupings, from relatively shallow-water taxa (BA3, globetum) to deep-water mud-dwelling ones (BA5, deeper brachiopodetum). The richest beds are M1-IIa (28 brachiopod species), M3-7 (23 species), and M0-9 (22 species). Eighteen species described here were not known previously in the Holy Cross Mountains, so the corrected total number of brachiopod species from the Middle Devonian of the Łysogóry Region is 140.

Zasoby przyrodnicze są wspólnym dobrem ludzkości, gdyż zapewniają jej warunki do życia. Przyroda, a dokładniej ekosystemy biosfery, dostarcza społecznościom ludzkim poprzez różnego rodzaju dobra i usługi wiele korzyści (np. żywność, wodę, niezanieczyszczoną glebę, możliwości pochłaniania dwutlenku węgla, regulację klimatu, substancje farmaceutyczne, surowce naturalne, miejsca rekreacji). Ogólnie nazywane są one usługami ekosystemowymi, będącymi stanami i procesami, dzięki którym ekosystemy podtrzymują i wypełniają ludzkie procesy i potrzeby życiowe.

Chociaż wiedza oparta na podstawach naukowych i technologie stosowane dla ochrony i poznania różnorodności biologicznej, jej wartości, funkcji, stanu i kierunków zmian, a także konsekwencji jej utraty, są ulepszane, to jednak nie są szeroko rozpowszechniane, przenoszone, a zwłaszcza stosowane. O działaniach tych nie decydują eksperci, ale niemający o tym żadnego pojęcia politycy. Zapadające decyzje nie mają nic wspólnego z fachowością i podejmowane są w polityce bez wartości. Jak zawrócić z tej zgubnej drogi?
