Teza. Badania jakościowe, uznawane przez wielu badaczy za subiektywistyczne i przez to mało wiarygodne, reprezentują jeden z wielu sposobów prowadzących do obiektywnego poznania. Omówione koncepcje. W artykule autorka omawia koncepcję Susan E. Chase dotyczącą wywiadu narracyjnego oraz koncepcję tożsamości narracyjnej w wywiadzie biograficznym Dana McAdamsa. Opisuje także podejście autobiograficzne oraz podejście auto/biograficzne, wskazując na istotne różnice między nimi. Podaje przykłady zastosowań obu podejść. Wyniki i wnioski. Dzięki biografiom i autobiografiom badacz ma możliwość poznania kontekstu sytuacyjnego, środowiskowego i historycznego badanego zjawiska. Auto/biograficzne narracje dostarczają także wiedzy na temat kształtowania się życia psychicznego i całej osobowości człowieka. Oryginalność. Badania auto/biograficzne wykorzystywane są z powodzeniem w edukacji osób dorosłych. Pełnią wiele ważnych funkcji, m.in. poznawczą, krytyczną, wychowawczą, demaskatorską, terapeutyczną.

Thesis. Qualitative research, regarded by many researchers as subjectivistic and therefore unreliable, is one of many ways leading to objective cognition. Discussed concepts. In the article the author discusses the concept of Susan E. Chase regarding narrative interview and the concept of narrative identity in the biographical interview of Dan McAdams. It also describes both the autobiographical approach and the auto/biographical approach, indicating the significant differences between them. Additionally, it provides examples of the application of both approaches. Results and conclusions. Owing to biographies and autobiographies, the researcher has the opportunity to learn about the situational, environmental and historical context of the studied phenomenon. Auto/biographical narratives also provide knowledge about shaping one’s mental life and the entirety of human personality. Originality. Auto/biographical surveys are successfully used in adult education. They perform many important functions, including cognitive, critical, educational, unmasking, and therapeutic.

The text represents some of the results of a qualitative research aimed at the recognition of the life and professional careers of basic school headteachers. Attention is mainly focused on the presentation and interpretation of the advanced stages in headteachers’ careers. Following the previous explanatory study about the accession to the headteacher function and the stage of adaptation, the newly identified career stages are interpreted in relation to the developments in headteacher’s attitude to the execution of his/her function. This text brings empirically substantiated arguments explaining the direct relation between headteachers’ professional careers and school management and leadership.

The investigations of the impact of disturbance severity on recruitment of clonal plant species were preformed in three Molinietum caeruleae patches dominated by small meadow species (MC), or prevailed by tall grasses (GR) or overgrown by willows (SA). The meadows were located in Vistula valley close to Kraków agglomeration, southern Poland. In above menntionned patches ten permanent experimental plots were randomly arranged. Each plot was divided in four subplots measured 900 cm² represented undisturbed control, low level of disturbance (the litter and the moss layer removal), intermediate level of disturbance (the litter, moss and above-ground vegetation removal), high level of disturbance (the litter, moss and the plants removal as well as top soil raking). The colonization of gaps was observed in the years 2008–2010. Irrespective of patch character, the greatest species richness and seedling abundance were observed in gaps, which occurred in result of intermediate disturbances. Weaker recruitment rates were recorded in openings left after disturbances of low- and high severity, while in fully compact herb layer no seedlings were found. In MC patch, regardless of treatment in all openings similar spectra of life history traits were observed. In seedling pool of all subplots appeared taxa creating below ground organs of clonal growth. In all subplots dominated species with intermediate values of lateral spread, numerous vegetative descendants, short-lasting stems and no persistent genet integration. In sites GR and SA in openings left after weak disturbances appeared species with below- and aboveground organs of clonal growth. The majority of them characterized by slight lateral spread, low number of vegetative offsprings, long lifespan of shoots and persistent genet integration. The abundance of taxa creating underground clonal growth organs, with considerable vegetative spread, high production of daughter ramets, short lifespan of shoots and not enduring genet integration increased gradually and significantly with disturbance gradient. Although the greatest recruitment rates were found in gaps left after removal of litter, moss and above-ground parts of plants, the most effective way for conservation of Molinietum caeruleae meadows appeared to be creation of different severity disturbances. Such treatment contributes to maintenance of heterogeneity of clonal species composition, especially in patches in advanced successional stages.

Small insectivores and rodents, despite similarities in body size and attributes scaling to body size, exhibit significant differences in other properties, including many life history traits. In this article major differences between life history traits of the two taxa are reviewed, with an indication of contrasting selection pressures related to somewhat different body size, as well as to differences in metabolic rates, diet and exposure to predation. Additionally, since the life history differences between small mammals are particularly well pronounced in highly seasonal habitats, the winter ecology of shrews and rodents is compared. Finally, the two different reproductive strategies typical for soricine shrews and small nonhibernating rodents, are presented. In conclusion, it is proposed that the reproduction delayed to the second calendar year of life in shrews is the result of selection for traits ensuring successful survival in winter, a period that is more perilous for shrews than for rodents. In rodents, in contrast, opportunistic reproduction is the most prominent characteristic which also helps to maximize their reproductive output. This ability for high reproduction seems to be the main antipredatory measure selected for in rodent evolution.

This article raises the issue of immigration to Canada of Poles who came to that country in years 1945–1989. The text consists of three parts. The first relates to the theoretical concept of “trajectory” and “biographical learning”, which approximates the various positions and approaches to the concept of learning from its own experience. In the second part I focus on the beginnings of Polish immigration to Canada, the present wave of Polish migration and I briefly characterize the situation of Polish pioneers and veterans of World War II in the province of Manitoba. The third section attempts to describe the difficulties and (self-) reflection in the narrative on own experiences and biographical learning in the context of own biography subjects.

W artykule poruszone zostały kwestie związane z imigracją Polaków do Kanady, w latach 1945–1989. Tekst składa się z trzech części. Pierwsza z nich dotyczy podstaw teoretycznych – koncepcji „trajektorii” i „biograficznego uczenia się”, w której przybliżam różne stanowiska i podejścia do koncepcji uczenia się z własnych doświadczeń i przeżyć. W drugiej części koncentruję się na przybliżeniu Czytelnikowi początków imigracji Polaków do Kanady, przedstawiam fale polskiej emigracji oraz pokrótce charakteryzuję sytuację polskich pionierów oraz weteranów II wojny światowej w prowincji Manitoba. W trzeciej części podejmuję próbę opisu trudności i (samo)refleksji w narracji dotyczącej własnych przeżyć i doświadczeń biograficznych w kontekście uczenia się z własnej biografii osób badanych.

The aim of the article is to present the methodological possibility of combining the biographical perspectives in the research strategy and to show its cognitive results. It is an invitation to drawing a reflection on the two different views of the world of Polish senior immigrants’ in Sweden – the outlook of a researcher and a photographer. It is a trial of join the world of science with the world of art. The article presents the possibility of using the photos/portraits of researched people to deepen the research and to show the meaning of photography in biographical approach. The paper proposes a model of coherent biography as a result of combination of the biography of narration (heard from the narration) with biography of photo (life history of researched people “read”/created from the portraits by addressees of the portraits). The analyzed data came from research done among a group of Polish senior immigrants in Sweden.

Balea fallax (Rossm.) collected from the Roztocze Upland (SE. Poland) was kept in the laboratory for four years. Observations were conducted between March and October when the snails were kept at room temperature (18-25°C); in winter they were stored at 3°C. The egg-laying period started in late March and lasted till October, with maxima in spring and early autumn. The snails laid oval, gelatinous eggs with separatecalcium carbonate crystals in the external envelope (average egg size 1.96 × 1.73 mm). The eggs were deposited in batches (up to 14 eggs at a time) or singly. The number of batches per snail per year ranged between 1and 4. Snails isolated before maturation laid defective eggs which failed to develop, which suggest that the speciesis incapable of uniparental reproduction or at least the ability is very limited. The reproduction rate decreased during consecutive years, probably as a result of the aging or the shortage of allosperm in isolated individuals.Compared to batches of typically oviparous clausiliids, eggs of B. fallax hatched slightly earlier (interval between oviposition and hatching lasted 8-10 days at room temperature). It is likely that the adults retained developing eggs in the uterus for a short time. The juveniles needed at least 6 months to attain the ultimates hell size.

Genetic diversity and spatial variation of two populations of Filipendula ulmaria (L.) were analysed at the initial stage (macroforbs) and the late succession stage (forest community) during a 30-year succession on the abandoned meadows in Białowieża National Park. The study demonstrated a high level of genetic diversity in both populations (D = 0.86 and D = 0.79 in the population at the initial and late succession stage, respectively). Significant genetic differentiation was observed at the cross-population level (FST = 0.008, P <0.001). Among 303 ramets in the population at the initial stage 261 genotypes were detected, of which 24 were clonal, and the remaining (237) were unique (91%). In the population at the late succession stage 92 genotypes were detected among 116 ramets of which 10 were clonal, and 82 unique (89%). The results did not confirm a hypothesis that the low level of the population.s genetic diversity should be expected at the late succession stage. Additionally, the study demonstrates that the prolonged clonal spreading does not always result in genetic monotony of a population. It has been demonstrated that the high level of genetic diversity in the population of clonal species F. ulmaria could be the result of temporal changes in life history traits of long-lived genets. The formation of gaps caused by the disintegration of senile genets and the permanent recruitment of seedlings over 30 years of population development reinforce the appearance of new genets. This process was reflected in both populations by the domination of unique genets and spatial pattern of genotypic diversity.

We examined the variation in the date of the onset of egg laying and clutch size in three peripheral populations of the Afrocanarian Blue Tits Cyanistes teneriffae ultramarinus at the edge of the species and subspecies geographic range. This study was carried out in three study sites, 130–290 km apart, in similar geographic conditions of the South Border Range of the Saharan Atlas in Algeria. Mean altitudes of nesting territories were between 1327 and 1437 m a.s.l. Habitats of the study sites were covered by the secondary, human-modified vegetation, ranging from a maquis shrubland, with the Holm oak Quercus ilex shrubs to woodlands dominated by the Atlas cedar Cedrus atlantica or by the Aleppo pine Pinus halepensis. 169 wooden nest-boxes were monitored for breeding parameters (laying dates and clutch sizes) during the breeding seasons 2007–2009 and 2011–2013. The timing of egg laying was relatively late for the latitude of the study sites, with overall mean laying dates varying between the study sites from 4 to 13 May. The laying date was influenced by the altitude of nesting sites, with the dates being delayed with increasing altitude. Overall mean clutch size differed between the study sites from 5.91 at Djelfa to 8.43 at Aflou. Clutch size tended to decrease with the advance of the breeding season. Because the study populations inhabit areas of similar physical conditions (climate and altitude), the main inter-population source of variation in the breeding parameters studied was probably variation in habitat quality.

A hypothesis has been put forward that low pH or high concentration of total phosphorus (TP) and dissolved organic carbon (DOC) in the lake water are the factors responsible for observed extinction of the population of Luronium natans (L.) Raf., protected macrophyte species from the group of isoetids. A study was performed on 525 generative individuals collected from 21 lakes in Pomeranian Lakeland (NW Poland) and a correlation between the biometric characteristics and environmental conditions in the lakes was tested. The following life history traits have been analysed: size of individuals, their fecundity and allocation of biomass. The greatest and most fecund individuals grow in the lake water of pH 6.1–7.0, poor in TP (10.1–20.0 µg dm⁻³) and DOC (3.5–6.0 mg C dm⁻³). The allocation of biomass of the individuals growing in the optimum conditions is as follows 46–54% in the leaves, 22–31% in the roots and 20–27% in the rhizome. In the lakes with water of pH < 5.0 or of TP > 20.1 µg dm⁻³ and DOC > 6 mg C dm³, a statistically significant decrease in the size of the individuals and unfavourable changes in the biomass allocation are found. The main environmental factor responsible for dying out of local populations of Luronium natans is a decrease of pH below < 5.0.

Taxonomic and biological-ecological information as well as literature pertaining to the eleven Polish representatives of glossiphoniid leeches are summarized. Taxonomic status of many species is unclear, and data on their life histories are often fragmentary. The existence of several different conflicting systems of glossiphoniid classification indicates that the taxonomical value of characters is unclear. The family requires a thorough modern revision. A new generic-level classification of the family is needed. Data on behaviour and life cycless of most species should be supplemented; anatomical variation and differences between the purported forms of glossiphoniid species should be re-examined. A detailed study on the life cycles and variation of the Polish members of the Glossiphoniidae would provide new and valuable data and would allow at least for proposing a good, modern standard of species description without which a world-wide revision is hardly possible.
