Jerzy Liebert was a poet creating his literary work during the interwar period (1904-1931). Initially, he was influenced by romantic comprehending of the world, later he moved towards metaphysical lyric poetry. The present text is aimed at showing the relationship between Liebert´s literary work and the poetry of the Samander literary group which characteristic features, among other things, are: presentism (comprehended as relationship with the present time), vitalism, pacifism, universalism, and urbanism. At the topic level it is seen when Liebert reaches for the elements of biologism or for the cult of spontaneity, and when he calls on the motiv of wine or drunkenness. It is also possible to point at the kinship of Liebert with the Skamander´s "big five" in the sphere of versification. Altough the poet set him free from the influence of the Skamander group about 1926, it can be stated that it was an important period in the evolution of his poetry.
The taxonomic classification of some parasitic isopods of the family Gnathiidae has been revised in the last years. However, their biological cycles have been described only partially or incompletely. Gnathia maxillaris (Montagu, 1804) is one of the most studied species, but certain aspects of its life cycle are still poorly known. A detailed study on the life cycle of G. maxillaris was carried out over several years by sampling larvae from an infestation of large volume aquaria at the Aquarium of Barcelona. At the same time, a system of in vitro cultivation of G. maxillaris was developed, which provided new data to complete the description of its life cycle. Periods of incubation, fertilization, planktonic stages, the attachment site on the fish host and biometric characteristics of larval forms were detailed. The new information may help better control health state of marine fish in aquaculture.
The interception was recognized as an important part of the catchment water balance in temperate climate. The mountainous forest ecosystem at experimental headwater catchment Liz has been subject of long-term monitoring. Unique dataset in terms of time resolution serves to determine canopy storage capacity and free throughfall. Spatial variability of throughfall was studied using one weighing and five tipping bucket rain gauges. The basic characteristics of forest affecting interception process were determined for the Norway spruce stand at the experimental area - the leaf area index was 5.66 - 6.00 m2 m-2, the basal area was 55.7 m2 ha-1, and the crown closure above individual rain gauges was between 19 and 95%. The total interception loss in both growing seasons analyzed was 34.5%. The mean value of the interception capacity determined was about 2 mm. Throughfall exhibited high variability from place to place and it was strongly affected by character of rainfall. On the other hand, spatial pattern of throughfall in average showed low variability.
