The aim of this thesis is to elucidate the tension between feminism and nationalism in Israel and to investigate the ways by which such discursive currents mark the identities of Israeli women. The specific field of investigation is Israeli theatre, and the identities examined are dramatic characters created by the Israeli playwright Miriam Kainy. Also examined is the character of the playwright herself. Theatre is being observed as a specific field of society in which the position of women can be clarified. What kind of women characters the Israeli theatre produces is therefore a leading question for this study. Feminist theories, focusing on gender aspects of power relations, together with the postcolonial perspective, which considers power relations by focusing on ethnicity and geopolitical aspects, provide the theoretical tools. The social constructionist viewpoint is used since it provides an appropriate understanding of important notions for the thesis, such as nation and identity, considering them as constructions created by discourse. The discourses focused upon are the national v. the feminist discourse and theatre is viewed as a discourse mediator, which is why the dramatic text is the object of the analysis. The specific method of analysis is inspired by Norman Fairclough’s critical discourse analysis. The main part of the thesis consists of a discursive analysis of five women characters, constructed within a period of about five decades, namely between the 1950s and 1990s. Each one of these characters consists of an articulation which is considered representative of a specific time-relevant discursive struggle between the two discourses in question. One of the central assumptions of the thesis is that the Israeli national identity is thoroughly masculine. The identity problems it has been causing Israeli women since the time of the pioneers until today are clearly illuminated throughout the analysis. The conclusion emphasises that the subjectpositions being introduced by Israeli national discourse, namely the ways of being a New Jew, an Israeli, collide with those introduced by feminist discourse, i.e. ways of being an independent woman subject. Nevertheless, each and every character demonstrates creative ways of transforming the discourses by aiming at a hybrid formation.

Conservatism is a central theme of organismic evolution. Related species share characteristics due to their common ancestry. Some concern have been raised among evolutionary biologists, whether such conservatism is an expression of natural selection or of a constrained ability to adapt. This thesis explores adaptations and constraints within the plant reproductive phase, particularly in relation to the evolution of fleshy fruit types (berries, drupes, etc.) and the seasonal timing of flowering and fruiting. The different studies were arranged along a hierarchy of scale, with general data sets sampled among seed plants at the global scale, through more specific analyses of character evolution within the genus Rhamnus s.l. L. (Rhamnaceae), to descriptive and experimental field studies in a local population of Frangula alnus (Rhamnaceae). Apart from the field study, this thesis is mainly based on comparative methods explicitly incorporating phylogenetic relationships. The comparative study of Rhamnus s.l. species included the reconstruction of phylogenetic hypotheses based on DNA sequences. Among geographically overlapping sister clades, biotic pollination was not correlated with higher species richness when compared to wind pollinated plants. Among woody plants, clades characterized by fleshy fruit types were more species rich than their dry-fruited sister clades, suggesting that the fleshy fruit is a key innovation in woody habitats. Moreover, evolution of fleshy fruits was correlated with a change to more closed (darker) habitats. An independent contrast study within Rhamnus s.l. documented allometric relations between plant and fruit size. As a phylogenetic constraint, allometric effects must be considered weak or non-existent, though, as they did not prevail among different subclades within Rhamnus s.l. Fruit size was correlated with seed size and seed number in F. alnus. This thesis suggests that frugivore selection on fleshy fruit may be important by constraining the upper limits of fruit size, when a plant lineage is colonizing (darker) habitats where larger seed size is adaptive. Phenological correlations with fruit set, dispersal, and seed size in F. alnus, suggested that the evolution of reproductive phenology is constrained by trade-offs and partial interdependences between flowering, fruiting, dispersal, and recruitment phases. Phylogenetic constraints on the evolution of phenology were indicated by a lack of correlation between flowering time and seasonal length within Rhamnus cathartica and F. alnus, respectively. On the other hand, flowering time was correlated with seasonal length among Rhamnus s.l. species. Phenological differences between biotically and wind pollinated angiosperms also suggested adaptive change in reproductive phenology.
