    Opis:
    Pedunculate oak (Quercus robur L.) is an important component of temperate forests in the north- ern hemisphere. It occurs naturally across Europe and in parts of North Africa, the Balkans, the Urals and the Caucasus. In Poland, it predominantly grows on the plains at ≤700 m a.s.l. The main objective of this study was to determine how different temperature-humidity growth conditions influence dormancy breakage and epicotyl emergence in Q. robur, using growth curve models. We also in- vestigated whether these differences result from changes in the climatic conditions under which the oak populations grow naturally. In this study, we selected four pedunculate oak stands in western and eastern Poland. These sites were char- acterised by oceanic and continental climates, respectively. Mature acorns were collected in the autumn of 2016 and pretreated for two weeks in the cold (4 °C). The acorns were then sown in plastic pots filled with a peat/sand substrate. Four climatic variants (cold-dry, cold-wet, warm-dry and warm-wet) and a control (average conditions) were used. Epicotyl emergence was monitored daily for 74 days. Epicotyl emergence dynamics (maximum absolute growth rate, lag time, T50), number of days to epicotyl emergence, and cu- mulative epicotyl emergence were measured or calculated. The acorns from oceanic climates required more intense warm humid conditions for epicotyl emergence than those from continental climates. In contrast, acorns from continental climates had an evolutionary advantage in that their epicotyl emergence occurred both in cold-dry and warm-wet seasons. This indicated that each population was adapted to its local environment.

    Opis:
    The paper considers the approaches and possibilities of using two types of simulation: the species distribution model and the ecological niche model. The study aimed to simulate favorable habitats and the potential spread of non-gregarious locust pests in North Kazakhstan based on satellite and ground data for preventive measures. The MaxEnt software was used to conduct the simulation. According to the species distribution model, high indicators of the habitat are predicted in the Pavlodar and Kostanay regions, on 69.9–100% of the studied territory. With the simulation of ecological niches for non-gregarious locust pests, the following class boundaries were determined for the transition from quantitative to qualitative indicators from I (85–100%) to IV (0–50%), which indicates the zones of the probability of pest attack from a higher indicator to a lower one. According to the fundamental model, high indicators of the area of pest occurrence, that is, zones I and II, are located in the central and northern parts of the Pavlodar region. Here, the probability of non-gregarious locust occurrence of zone I and II with a ratio of 1:1 is observed in a slightly arid, moderately warm agro-climatic zone. In the southern part of the Kostanay region, the simulation predicts the probability of occurrence on zones I and II with a ratio of 1:2 in the moderately arid warm agro-climatic zone of this region. In the southern and southeastern parts of the Akmola region, the model predicts the probability of occurrence in zones I and II with a ratio of 1:3 in a slightly humid, moderately warm agro-climatic zone of the region. The considered species distribution model can be used as a modern tool for long-term forecasting of the spread of non-gregarious locust pests since it takes into account the peculiarities of the agricultural landscape. The fundamental niche model can be used in a long-term population forecast since it focuses more on the theoretical conditions of pest habitats.

    Opis:
    The article discusses the role of the soil aggregate structure in quantifying the marginality and specialisation axes of the ecological niche of the micromollusc Vallonia pulchella (Muller 1774) that inhabits technosols. The experimental polygon consisted of 105 samples located within 7 transects (15 samples each). The distance between rows of sampling points was 3 m. The average density of V. pulchella was 1393 ind.∙m-2. The soil aggregate fraction of 1–5 mm was found to be predominant within the technosol. The spatial variation of aggregate fractions was characterised by a moderate level of the spatial dependence. It was impossible to choose an adequate covariance model from among the traditional ones to interpolate the spatial variation of aggregate fractions, and only the Matérn model was best suited. The axis of marginality and specialisation of the V. pulchella ecological niche projected in soil aggregate fractions was significantly different from a random alternative. The ecological niche of the V. pulchella was presented by integral variables, such as the axis of marginality and specialisation, which were the basis to build a map of the spatial variation of the habitat suitability index. The marginality of the V. pulchella ecological niche correlates with soil penetration resistance indicators at depths ranging from 0–5 to 20–25 cm, soil humidity, acidity, and aeration. The specialisation correlates with the soil mechanical impedance at 25–35 cm, nitrogen content, and the soil acidity regime.

    Opis:
    There is an old problem in philosophy: the problem of how we pass from the mental theater of our representations to the external realm of concrete physical objects - from the "inner” to the "outer” . This problem arises against the background of representationalist theories of the relation between mind and its objects, theories that have taken different forms since Descartes, Kant, Helmholtz or Brentano. Representationalist theories of perception are marked by the following three features: 1. The perceiving subject is idealized. It is conceived as lying outside any context or environment and in abstraction from any goal-directed behavior. 2. Perception is seen as beginning with raw or bare sensations; then, by a process of inference or deliberation, there arise beliefs about external, physical objects. 3. Physical objects are assumed to be out there in the world, but to be inaccessible to direct experience. Our knowledge of them is indirect; it is the product of hypothesis and inference. This representationalist theory lives on in the computational theories of the mind and in doctrines of "methodological solipsism” embraced by much contemporary cognitive science. But the theory rests on a mistake. By making perception dependent on sensation, and by making sensations the direct objects of experience, it has matters exactly upside down. The paper draws on the ecological psychology of J. J. Gibson and Roger Barker in order to provide the metaphysical principles of a more adequate theory.

    Opis:
    The therapeutic potential of the forest results mostly from the accumulation of volatile organic compounds produced by the forest plants. These compounds are found in the highest concentration in the air space between the soil and the tree canopy and they are important cofactors in the regulation of various physiological processes of the human body. Both, the chemical structure as well as the regulatory function of these substances, are already known, or have been studied by pharmacologists and biochemists. What is not known, however, is the spatial variability in concentration of these compounds in the air of forest ecosystems and its dependence on the genetic or developmental structure of the biocenosis. This presents a challenge, which can only be overcome by forest research institutions ready to adopt new methodology, which is needed in order to study the spatial distribution of therapeutic potential within the forest environment. The main outcome of such research should be updated guidelines for the management of silviculture. Some concepts useful for establishing appropriate research programs are suggested in this paper. In line with these concepts, aspects of evolution of the human ecological niche idea associated with forestry management, and the idea of the human place in nature, are also discussed.

    Opis:
    The aim of this paper is to show how a monastic environment can be regarded as providing shelter for individuals with autism spectrum condition in the Middle Ages. By drawing on the recent literature in the history of medicine that traces the signs and symptoms of ASC in Hildegard of Bingen, a Benedictine abbess from the twelfth century, we will turn to her invented language Lingua Ignota as a source of justification for her diagnosis and as one manner in which she managed her neurodivergence. We invoke contemporary embodied and ecological approaches to cognition and its impairments in order to understand how the medieval monastic socio-material niche could have played a crucial role in the inclusion of individuals with ASC, and as providing a therapeutic environment.
