Kas yra lietuvis? Vladislavo Mickevičiaus tėvynės paieškos

Władysław Mickiewicz (1838–1926) was one of most active members of the Polish-Lithuanian diaspora: biographer, journalist, librarian, translator, political, social activist, and prolific publicist. Despite all this, he was mainly known as a son and a follower of his father, the great poet Adam Mickiewicz. The lives of these two men intertwined in many ways: both of their youth years were marked by great rebellions, and both had missed them, both having spent most of their adult lives in Paris, writing and dreaming about their motherland. However, while for Adam the motherland was the land of his childhood and youth, for Władysław, it was not that easy to define. For him, Lithuania, Poland, and his great Father had formed a certain ideal – an ideal to live for. Władysław Mickiewicz was a servant of this ideal all his life, constantly pre-serving, popularizing, and sometimes interpreting it – the legacy of his father. These ideals of an eternal Union between Poland and Lithuania, of an archaic Lithuanian Arcadia somewhere in a secluded part of the world, looked so natural in the Romantic days of the poet. It had grown less and less clear at the second part of the 19th century, and especially during the turbulent years of the First World War and the beginning of the interbellum, which brought such a sharp division between Polish and Lithuanian identities, making old ideals appear strange and antiquated. Yet despite this, Władysław Mickiewicz never renounced them. This article explores his life, writings, and the interpretations of the works of his father with the hope of finding his true motherland.Straipsnyje pristatomas Adomo Mickevičiaus sūnaus, leidėjo ir biografo Vladislavo Mickevičiaus gyvenimas, jo pažiūrų ir tautinio identiteto evoliucija, ypatingą dėmesį skiriant jo santykiams su Lietuva („Lietuvomis“ – realiu kraštu ir pusiau mitologine jo tėvo tėvyne). Amžių sandūroje kuriantis nepriklausomoms valstybėms, tautinio identiteto problema paliečia ir išeiviją. Atskleidžiama V. Mickevičiaus transformacija: nuo aktyvaus kovotojo už unijinę Lietuvos–Lenkijos valstybę iki idėjinio vizijoje likusios valstybės tėvynainių rėmėjo

Occurrence and biology of Pseudogonalos hahnii (Spinola, 1840) (Hymenoptera: Trigonalidae) in Fennoscandia and the Baltic states

Pseudogonalos hahniiis the only known species of Trigonalidae in Europe. It is a hyperparasitoid of lepidopteran larvae via ichneumonid primary parasitoids. Possibly, it has also been reared from a symphytan larva. We report the species for the first time from Estonia, Lithuania and Russian Fennoscandia, and list all known observations from Finland and Latvia. An overview of the biology of the species is presented with a list of all known host records

Dešimties Eumeninae pošeimio klosčiavapsvių poravimosi palyginimas, trumpai apžvelgiant lytinės atrankos teorijas: tolesnių tyrimų kryptys

This paper represents an initial attempt to examine mating phases of ten wasp species of the genera Ancistrocerus, Discoelius and Symmorphus, posing the questions as to what species traits are potentially involved in interactions between sexes, and what forms of sexual selection impel the evolution of these traits. The studied species significantly differ in the sex ratio and the relative body size of sexes, their willingness to mount and copulate, male displays (mode and frequency of antennation and position while copulating), female displays (intensity and frequency of rejecting behaviour), the presence of the male's copulatory and postcopulatory courtship. Results of the comparative study of mating behaviour are discussed in parallel with the review of literature on sexual selection and sexual conflict, defining the framework for future research. Single locus complementary sex determination (sl-CSD), regular inbreeding and female uniparental care in combination with predominant monandry are the features of these wasps that allow to use them as a model for studies into understanding of the evolutionary maintenance of monandry
