The complexity of invasion process of alien species is very high and requires better understanding. Nowadays, the successful range expansion of Erechtites hieraciifolia is being observed in Poland. In the study, the distribution of the species in Poland was summarized, based on the available literature and new field data. The fieldworks were conducted in the part of the species expansion zone located in central and north-eastern Poland. Two case studies on species encroachment into post-fire and transitional bog communities were performed and a case inventory of the species presence on the border of its main secondary range was conducted. The measurements of height, counting of the number of inflorescences per individual and the number of achenes per flower head were conducted in selected stands. There was performed a checking of local conditions of growth using ecological indicator values for vascular plants. The analyzed specimens of the species had significantly less inflorescences and achenes than in the other parts of the species expansion zone. They grew also in worse light conditions and in less fertile sites. The species colonized most disturbed patches at first. It spread to the less disturbed ones and omitted natural sites. The massive colonization of the transitional bog could be caused by groundwater level lowering. In the area of the edge of the species main range it was found in many diffuse stands within disturbed patches of the landscape. Based on the obtained results the species is considered to create now still only a moderate threat in the analyzed part of the expansion zone. The possibility of its expansion to wetland sites and sudden appearance in Kampinos National Park needs much more attention. Key words: alien invasive species, climate change, American burnweed, expansion, disturbance

This paper presents the results of a 3-year field experiment conducted in north-eastern (NE) Poland to determine the influence of the autumn application of foliar macronutrient and micronutrient fertilizers (control, one application in BBCH (Biologische Bundesanstalt, Bundessortenamt and Chemische Industrie) stage 16 (six leaves unfolded)), two applications in BBCH stages 14 (four leaves unfolded), and 16 (six leaves unfolded) on the growth and development of winter oilseed rape plants, nutrient accumulation, overwintering success, yield components, yield, nutritional value (crude fat content, fatty acid concentrations), and feed value (total protein content, concentrations of acid detergent fiber and neutral detergent fiber, quantitative and qualitative composition of glucosinolates) of seeds. When applied in BBCH stages 14 and 16, foliar fertilizers stimulated the development of leaf rosettes, increased the accumulation of minerals in aerial rosette parts (N, K, and Mg) and roots (K, Cu, Mn, and Fe), and contributed to the overwintering success of winter oilseed rape plants (by 8–11%). The application of foliar macronutrient and micronutrient fertilizers in autumn increased seed yield (by 0.25 Mg ha−1), contributed to a significant increase in the crude fat content of seeds (by 1.3–7.4 g kg−1 dry matter (DM), increased the content of oleic acid, decreased the concentration of linoleic acid, and increased the content of glucosinolates, mostly the alkenyl fraction with antinutritional properties.

Abstract During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia), rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Białowieża National Park (NE-Poland) indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

The article presents the earliest ceramics of the site Szczepanki, north-eastern Poland, belonging to the Para-Neolithic Zedmar culture, which existed in the south-east Baltic region. The presented pottery come from the Late Atlantic layers, dated 5600–5100 conv BP. The pottery is discussed regarding the technology, morphological details, vessel forms and ornamentation. Each of the elements shows multidirectional influences or similarities with the Western and the Eastern Para-Neolithic, as well as the Danubian cultures and the TRB. However, a specific characteristic of the early Zedmar pottery relies on mixing features of various origins or traditions, creating a new and peculiar technology and style.

Agricultural heritage is gaining increasing importance as a repository of lessons to be learned for more sustainable agriculture in the future. Among the forgotten European agricultural heritage, the Italian grapevine “coltura promiscua,” which integrates agroforestry and intercropping, survives only in a few regions in the form of relics. Based on geographic, historic, agricultural literature published on the subject between 16th and 20th century with a focus on North eastern Italy, on previous fieldwork research, and on the analysis of recent candidacies to the Italian National register, this contribution identifies five principles that can be considered today as lessons of sustainability in agriculture: vertical intensification, spatial multifunctionality, resilience through crop diversity, labour-intensive production, personal/familiar/community attachment. Taken together, these principles describe a new rationality that seems to adapt to changed global and local conditions and can suggest new strategies to design new sustainable agricultural systems. The research suggests that sustainability principles can be found both by studying relics of agriculture heritage, and by carefully reading the literature that described them in the past, well before the concept of sustainability itself appeared in the scientific debate. Finally, this paper highlights some difficulties in practicing these lessons in modern agroforestry systems and suggests directions for future research.

Abstract Background Spirometra erinaceieuropaei is a diphylobothriid tapeworm with a complex life-cycle including definitive, intermediate and paratenic (transport) hosts. Multiple routes of parasite transmission often make it impossible to determine what type of host a specific infected animal is considered to be. Spargana larvae cause sparganosis, a severe food- and water-borne disease mainly found in Asia. In Poland, Spirometra sp. was reported in large carnivores in Białowieża Primeval Forest for the first time in the 1940s and was recently confirmed as S. erinaceieuropaei in several mammals and snakes using molecular methods. Methods In total, 583 carcasses of 9 carnivore species were necropsied between 2013 and 2019 in north-eastern (NE) Poland. The larvae of S. erinaceieuropaei (spargana) were isolated from subcutaneous tissue, counted, and preserved for genetic analyses. We calculated the prevalence and intensity of infection. To assess spatial variation in S. erinaceieuropaei infection probability in NE Poland, we applied a generalized additive model (GAM) with binomial error distribution. To confirm the species affiliation of isolated larvae, we amplified a partial fragment of the 18S rRNA gene (240 bp in length). Results Spirometra larvae were found in the subcutaneous tissue of 172 animals of 7 species and confirmed genetically as S. erinaceieuropaei. The overall prevalence in all studied hosts was 29.5% with a mean infection intensity of 14.1 ± 33.8 larvae per individual. Native European badgers and invasive raccoon dogs were characterized by the highest prevalence. An analysis of parasite spread showed a spatially diversified probability of infection with the highest values occurring in the biodiversity hot spot, Białowieża Primeval Forest. Conclusions Our study revealed that various mammal species (both native and non-native) can serve as S. erinaceieuropaei reservoirs. The frequency and level of infection may differ between selected hosts and likely depend on host diversity and habitat structure in a given area. Further studies are needed to assess the distribution of the parasite throughout Europe and the environmental and biological factors influencing infection severity in wild mammals.

Changes of the abundance of the sawfly P. a. affinis were recorded during eight successive years in a study region extending from the Southern Tablelands of New South Wales to north-eastern Victoria. The influences and processes which affected mortality and reproduction in populations of the sawfly are described, and their contributions to the observed fluctuations of abundance in the study region are discussed. The major causes of mortality were desiccation, fungal disease, and parasitism. The main parasites were tachinids (Froggattimyia spp.) and a trigonalid (Taeniogonalos venatoria Riek). A variable proportion of the prepupae entered a diapause which persisted for 2 or more years. Although extended diapause ensured the survival of the subspecies during seasons unfavourable for its active stages, only a small proportion of the prepupae involved survived to emerge as adults. The consequences of very high numbers were: increased incidence of desiccation mortality and of extended diapause, and a decrease of the fecundity of the subsequent generation. Due to the benefits which accrued from colonial behaviour, survival of the larvae was greater at moderately high than at low densities. These density-regulating mechanisms of the life system of the sawfly operated conspicuously only at very high and very low densities. In the eastern portion of the study region, fluctuations of abundance were closely synchronized in all sites. These fluctuations could be interpreted in terms of changing environmental favourability during successive seasons. Analysis of weather data showed that departures from long-term average temperatures and rainfalls were correlated throughout the region. However, sawfly numbers fluctuated erratically in the western subregion, the changes of density there often being at variance with those consistent throughout the eastern subregion. Parasitism by T. venatoria, which was often very severe in the western subregion, was the only process recognized that was likely to be responsible for the differences observed.

Abstract The objective of this paper was an attempt to estimate the impact of variable habitat conditions on the ionic state and ionic balance of selected species of plants occurring in an environment with scarce anthropogenic pressure in the Piska Primeval Forest, north-eastern Poland. The analysed mono- and dicotyledonous plants showed very high amounts of total nitrogen, exceeding sum of alkaline cations (Ca2+, Mg2+, K+, Na+), particularly at poor natural habitats (Sphagno-girgensohni-Picetum and Pino-Quercetum communities). Lack of alkaline cations is probably compensated by nitrogen in the form of NH4+, therefore maintaining the ionic balance of cations and anions in plants. Plants inhabiting habitats such as the Tilio-Carpinetum community show very high amounts of potassium. Some potassium radioactivity is probably indispensable for the physiological processes in plants instead of solar radiation

Based on the experimental studies, the process of ground regeneration around the borehole loaded with brine-water heat pumps working exclusively for heating purposes in the period of four consecutive heating seasons in a cold climate was presented. The research was conducted in north-eastern Poland. The aim of the work is to verify the phenomenon of thermal ground regeneration in the period between heating seasons on the basis of the recorded data and to check whether the ground is able to regenerate itself and at what rate. It was noticed that the ground does not fully regenerate, especially during heating seasons with lower temperatures. In the analyzed period, from 22 September 2016 to 12 October 2020, the ground probably cooled irreversibly by 1.5 °C. In order to illustrate and evaluate the speed of changes in the ground, the one’s profile with an undisturbed temperature field was presented for each month of the year. The presented results can be a very important source of information for the analysis of geothermal conditions occurring in the ground. They can be used to verify mathematical models and conduct long-term simulations that allow us to see the complexity of the processes taking place in the ground.

New localities of <em>Arnoseris minima</em> (L.) Schweigger et Koerte (Asteraceae) in the Podlasie region (NE Poland) are presented. The current distribution of the species was established on the basis of the authors’ floristic field studies, revised herbarium materials, published data, and unpublished sources. The collected data enabled us to revise the map of the species’ distribution in the Podlasie region and supplement it with another new 17 localities. The previously established geographic range of species in Poland can now be moved by about 30 km eastwards and 50 km northwards. The identification of new locations of <em>A. minima</em> on the border of its continuous geographical range becomes important in the context of the declining number of localities of this species recently observed across almost the whole of Europe.
