Opis:
If D = (V,A) is a digraph, its niche hypergraph Nℋ(D) = (V, ℰ) has the edge set ℰ = {ℯ ⊆ V | |e| ≥ 2 ∧ ∃ v ∈ V : e = ND-(v) ∨ ℯ = ND+(v)}. Niche hypergraphs generalize the well-known niche graphs (see [11]) and are closely related to competition hypergraphs (see [40]) as well as double competition hypergraphs (see [33]). We present several properties of niche hypergraphs of acyclic digraphs.

Opis:
The aim of the study was to determine the requirements for organic food expected by Polish consumers. A method of diagnostic survey was used in the study with the author’s research tool in the form of a survey questionnaire. The sample consisted of 1102 respondents. The Statistica 10.1 PL program was used for statistical analysis, including the analysis of discriminant function. The production of organic food should take place naturally without harmful substances. In Poland, the organic production has the potential to produce high protein and micronutrient products as well as of a reduced toxin contamination. The main places to purchase organic food were discount stores and those specializing in selling organic food as well as organic farms. It was emphasized that the respondents placed great importance on the accreditation of the product certification body on food packaging as well as on labeling these products as produced in ecological conditions. Currently the organic food market is considered to be a niche, but its importance is steadily increasing.

Opis:
Tintinnid ciliates, characterized by the possession of a lorica into which the ciliate cell can contract, are a common component of the marine microzooplankton. Lorica architecture and size range widely and classically distinguishes species. Here relationships between ecological parameters and lorica dimensions (lorica oral diameter (LOD), lorica length (LL) and lorica volume (LV) are examined using data from literature reports. The relationships between lorica dimensions and reproductive potential, using maximum reported growth rates of natural populations (n = 52 species) are assessed. Susceptibility to copepod predation and lorica dimensions are considered based on reports of clearance rates of Acartia species feeding on tintinnid ciliates (n = 7 species). Diet and lorica dimension is analyzed using data on mean maximum food size contained in field-caught cells (n = 20 species), and preferred food size based on prey size associated with maximal reported clearance rates (n = 15 species). Overall, LOD is closely related to most of the ecological parameters. Maximum growth rate is related to LOD with smaller LODs corresponding to higher growth rates, in contrast to LL and LV. Maximum prey size is positively related to both LOD and LL but more tightly with LOD. Preferred prey size is positively related to LOD and LV but more tightly related to LOD. Clearance rates of Acartia species feeding on tintinnids are significantly related only to LOD with small LODs corresponding to lower copepod feeding rates. Relationships excluding data on species of Tintinnopsis, the species-rich genus which generally dominates coastal communities, are also examined and show similar trends. In tintinnids, LOD, known to be a conservative and relatively reliable species characteristic, appears related to a wide range of ecological characteristics.

Opis:
The main purpose of this article is to point out – on the basis of literature analysis and Au-thor’s own research results – the rationale for selecting strategies of a market niche and implementing niche marketing by small companies, often of a family nature, as well as to discuss the main criteria used to identify the category of a “niche company”. According to the Author, the concentration in a niche is an attractive course of action for small compa-nies and a manner of competition. The following arguments support the above: obtaining a higher return on sales, protection against global competitors selling cheaply and in masses, closer contact with customers and a long-term development of companies. This way they can avoid excessive risk, and thus reduce the risk of incurring losses.
Głównym celem artykułu jest wskazanie – na podstawie analizy literatury oraz wyników badań własnych autora – przesłanek wyboru strategii niszy rynkowej oraz implementacji marketingu niszowego przez małe firmy, często o charakterze rodzinnym, a także omówienie podstawowych kryteriów wykorzystywanych w celu wyodrębnienia kategorii „firma niszowa”. Zdaniem autora, koncentracja w niszy jest atrakcyjnym sposobem działania dla małych firm i sposobem konkurowania. Przemawiają za tym następujące argumenty: uzyskiwanie wyższej rentowności sprzedaży, ochrona przed globalnymi konkurentami sprzedającymi tanio i masowo, bliższy kontakt z klientami oraz długoterminowy rozwój firm. Dzięki temu unikają one nadmiernego ryzyka, a tym samym ograniczają zagrożenie ponoszenia strat.

Opis:
The niche graph of a digraph $D$ is the (simple undirected) graph which has the same vertex set as $D$ and has an edge between two distinct vertices $x$ and $y$ if and only if $N_D^+(x) ∩ N_D^+(y) ≠ ∅ or N_D^−(x) ∩ N_D^−(y) ≠ ∅$, where $N_D^+(x)$ (resp. $N_D^−(x)$) is the set of out-neighbors (resp. in-neighbors) of $x$ in $D$. A digraph $D = (V,A)$ is called a semiorder (or a unit interval order) if there exist a real-valued function $f : V → \mathbb{R}$ on the set $V$ and a positive real number $δ ∈ \mathbb{R}$ such that $(x, y) ∈ A$ if and only if $f(x) > f(y)+δ$. A digraph $D = (V,A)$ is called an interval order if there exists an assignment $J$ of a closed real interval $J(x) ⊂ \mathbb{R}$ to each vertex $x ∈ V$ such that $(x, y) ∈ A$ if and only if $min J(x) > max J(y)$. Kim and Roberts characterized the competition graphs of semiorders and interval orders in 2002, and Sano characterized the competition-common enemy graphs of semiorders and interval orders in 2010. In this note, we give characterizations of the niche graphs of semiorders and interval orders

If $ D = (V, A) $ is a digraph, its niche hypergraph \( N \mathcal{H} (D) = (V, \mathcal{E} ) \) has the edge set \( \mathcal{E} = \{ e \subseteq V \ | \ |e| \le 2 \land \exists υ \in V : e = N_D^− (υ) \lor e=N_D^+ (υ) \} \). Niche hypergraphs generalize the well-known niche graphs and are closely related to competition hypergraphs as well as common enemy hypergraphs. For several products \( D_1 \circ D_2 \) of digraphs \( D_1 \) and \( D_2 \), we investigate the relations between the niche hypergraphs of the factors \( D_1 \), \( D_2 \) and the niche hypergraph of their product \( D_1 \circ D_2 \).

Celem artykułu jest określenie motywacji i planów zawodowych małopolskich kobiet wkraczających w obszar ekonomii społecznej, w warunkach współczesnych przemian gospodarczych i społecznych w Polsce. Podstawowe pytanie badawcze skupiało się na tym, czego kobiety wkraczające w ekonomię społeczną poszukują dla swego rozwoju zawodowego oraz jaką własną ofertę planują w sektorze ekonomii społecznej utworzyć. Przeprowadzono badania jakościowe kobiet, które zakładały organizacje pozarządowe lub działały na rzecz społeczności lokalnych w ramach wsparcia z programu Ośrodka Wsparcia Ekonomii Społecznej w Krakowie. Wywiady pogłębione przeprowadzono na próbie 25 kobiet z terenu Krakowa. Zbadane kobiety znalazły pracę na szczególnych, nietypowych stanowiskach. Działając w sektorze ekonomii społecznej, mają wyjątkową odpowiedź na potrzeby swoich odbiorców oraz potrzeby własne. Tworzą dla siebie niszowe miejsca pracy, a jednocześnie tworzą niszową ofertę dla swoich odbiorców, którymi najczęściej są lokalne społeczności.
The aim of the article is to determine the motivations and professional plans of women from Małopolska who enter the field of social economy in the conditions of contemporary economic and social changes in Poland. The basic research question focused on what are the women entering the social economy looking for according to their professional development and on their own offer that they plan to create in social economy. Qualitative research was carried out on women who set up NGOs or act for the benefit of local communities as part of the support program of the Social Economy Support Center in Krakow. In-depth interviews were conducted on a sample of 25 women from Krakow. The respondents find work in special, atypical positions. By acting in the social economy, they create a unique response to the needs of their recipients and their individual needs. They create niche jobs for themselves, and at the same time create a niche offer for their recipients, which are most often local communities.

Opis:
The knowledge on chorology of species is basic for biogeographic and ecological studies and for conservation actions. The data on the chorology of Taxus baccata in Morocco have not been studied. The bibliographic resources, herbarium material, unpublished data of several botanists and the authors’ field notes have been reviewed. Two yew populations on Jbel Lakrâa in the Rif and near Bekrit in the Middle Atlas were measured to verify demographic structure and health conditions. The Maxent model of predicted habitat based on bioclimatic variables was used to evaluate the potential geographic range of T. baccata. The species occurs in the mountain areas of northern Morocco: in the Rif, the Middle and High Atlas, at altitudes between (500) 1200 and 2000 (2350) m. In the High Atlas, it reaches its southernmost locations within the geographic range. The populations represented by the highest number of individuals are found in the Western Rif and Middle Atlas, while from the High Atlas only single, isolated individuals are known. The yew occurred preferably in forests of Cedrus atlantica, Abies maroccana, groves of Betula fontqueri, Ilex aquifolium and Prunus lusitanica and in riparian forests located in narrow gorges. Seedlings were observed only at single localities. The population of T. baccata in the Rif presented a good health condition with successful regeneration, while the population in the Middle Atlas was in a much worse state, where only 4–8 m high yews were observed, without natural regeneration. The Maxent model of predicted habitat, based on bioclimatic variables, suggests that T. baccata could occur today in much broader mountainous areas in Morocco, especially in the Rif and Middle Atlas. However, the progressive decline of this species in Morocco indicates the significant importance of other factors on yew distribution, including microsite conditions and human pressure. Taxus baccata in Morocco is in regression at most of its localities and should be treated as a vulnerable species. Measures to ensure the yew’s conservation are needed, especially at its southernmost localities in the High Atlas.

Opis:
The article offers an analysis of the frequency and quality of LGBTQ+ representation in fictional podcasts. I examine how frequently and with what intent LGBTQ+ characters are included in this medium. This research aims to fill the gap in academic work on LGBTQ+ representation in podcasts. Though scholars note an increase in representation in mainstream media, LGBTQ+ media consumers, especially young people, still look to other sources for validation of their identities. Many LGBTQ+ people look to fictional podcasts as a source of quality representation, especially because podcasts are small-scale and rely on the funding, and thus the opinion, of listeners (Bottomley, 2015). In this paper, I analyze four fictional podcast series for LGBTQ+ inclusivity. I note how many LGBTQ+ characters are included and in what proportion. I assess the quality of representation in four ways: diversity, depth, and the frequency and type of stereotypical LGBTQ+ tropes. My findings show a high frequency of LGBTQ+ characters and diversity of personalities and backgrounds, opportunities for these characters to express their sexual and/or gender identities as well as LGBTQ+ trope subversions. Thus, we see that fictional podcasts, as a medium that sustains itself by listeners’ patronage, present stories that their audience can relate to. As a result, fictional podcasts create more niche stories that make connections with smaller demographics of media consumers.

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.

This paper seeks to explore the issues of innovation and new path creation in the UK and Germany, illustrated through the case of the modern wind power industry. Taking an evolutionary perspective drawing on path dependence theory, the paper examines the role of niche environments in the creation of new economic pathways. The research finds that new economic pathways are more likely to develop in places where niche conditions provide receptive environments for innovations to flourish. The policy implications of the research include the importance of supporting niche environments that encourage growth in new sectors and the need for financial support to bring innovations to market, to encourage the development of new economic pathways.

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.

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:
Darwinism, in all its various forms, seeks to explain evolution without the intervention of intelligence, purposefulness or in tentionality: in short, via the abolition of purpose. Yet life is arguably a profoundly purposeful phenomenon, most evident in the phenomenon of adaptation. Modern Darwinism fails because it has no coherent theory of adaptation, and hence no coherent theory of life. Without this, it cannot claim to be a coherent theory of evolution. Here, I argue that a coherent theory of evolution will arrive when the inherent purposefulness of life can be reincorporated into our evolutionary thinking. Life's fundamental property of homeostasis, coupled with the expanding conception of hereditary memory emerging from epigenetics and niche construction theory, can credibly restore purpose to our thinking about evolution. The evolution of lineages will no longer then be under the control of natural selection, but rather imbued with striving and intentionality: with “wanting” to evolve.
