Opis:
Celem przeprowadzonego doświadczenia było porównanie antagonistycznego oddziaływania grzybów z rodzaju Trichoderma oraz grzybów drożdżoidalnych na patogeny z rodzaju Fusarium w warunkach in vitro. W badaniach wykorzystano dwa gatunki grzybów z rodzaju Trichoderma: T. viride i T. harzianum, dwa gatunki grzybów drożdżoidalnych: Candida albicans i Trichosporon pullulans oraz pięć gatunków patogenów z rodzaju Fusarium: F. culmorum, F. graminearum, F. poae, F. oxysporum oraz F. avenaceum. Testowane grzyby wyszczepiano parami na pożywkę PDA. Doświadczenie wykonane zostało w dwóch seriach różniących się temperaturą inkubacji grzybów (20ºC i 26ºC). Pomiary prowadzono mierząc średnicę kolonii grzybów. Stwierdzono, że antagonistami o najsilniejszym działaniu na patogeny były T. harzianum oraz T. viride. Najsłabsze oddziaływanie na rozwój Fusarium spp. wykazał T. pullulans. Temperatura nie wpłynęła istotnie na działanie grzybów z rodzaju Trichoderma spp., natomiast C. albicans wykazał większą aktywność antagonistyczną w wyższej temperaturze. Wśród patogenów najbardziej wrażliwe na działanie antagonistów były F. graminearum, F. avenaceum oraz F. oxysporum.
The aim of the study was to compare an antagonistic activity of Trichoderma spp. and yeasts on pathogenic Fusarium spp. in in vitro conditions. Two Trichoderma species (T. viride and T. harzianum), two yeast species (Candida albicans and Trichosporon pullulans) and five Fusarium species (F. culmorum, F. graminearum, F. poae, F. oxysporum and F. avenaceum ) were tested. Fungi were inoculated in pairs on PDA plates and incubated in two temperatures: 20ºC and 26ºC. The fungi diameter was measured. T. harzianum and T. viride affected the pathogens the most and T. pullulans the least. Incubation temperature did not affect Trichoderma spp. C. albicans was more active in the higher temperature. Among pathogens the most vulnerable were F. graminearum, F. avenaceum and F. oxysporum.

Opis:
The paper presents the results of new studies of Quaternary deposits filling the Kleszczów Graben in the Szczerców outcrop, Bełchatów Lignite Opencast Mine. Sedimentary successions were profiled in the fieldwork. Moreover, the borehole data were studied. Laboratory studies included: grain size analyses, analyses of shape and morphology of quartz grain (morphoscopy), analyses of anisotropy of magnetic susceptibility (AMS), palynological, malacological and ostracodological studies, as well as geochronometric (C14) and geochemical (δ18O/δ16O) measurements. The studies were carried out in 2009–2013 and resulted in discovering of some sedimentary formations as well as arranging geological cross-sections and synthetic lithostratigraphic profile. The following sedimantary formations have been distinguished: Folwark, Kuców, Czyżów, Ławki, Rogowiec, Aleksandrów, Piaski and Widawka, arranged into two structural units: the lower one – deformed, and the upper one – undeformed.

Baltic Sea
Opis:
The Baltic Sea is not typically considered as an area affected by tsunamis. However, during the Late Pleistocene and Holocene several tsunami events have been interpreted from the sedimentary record, mainly in Sweden and Estonia. Furthermore, on the southern coast of the Baltic Sea, there are historical accounts of catastrophical marine floodings called “der Seebär” (“the Sea Bear”). Their descriptions reveal many features typical for tsunami, but their genesis remained unknown and sedimentary evidence for such events has not been found. Here we provide evidence of sandy event layers from the area of Rogowo, NW Poland – the area of historical catastrophic storms as well as “der Seebär” events. The study area is a low-lying coastal plain with an average elevation of –0.5 to +0.5 m a.s.l., protected from the open sea by beach and coastal dune systems up to 5 m high. Sedimentological, micropalaeontological and geochemical analyses along with AMS 14C dating were applied to sedimentary successions seen in 5 major trenches and 198 sediment cores up to 1.5 m long. Two sandy layers were identified in the peat deposits that developed on the plain during the last ~2000 years. They reveal a number of typical features of tsunami deposits (significant lateral extent and thickness, rip-up clasts, chemical and micropalaeontological evidence of marine origin), however, 14C dating along with the historical accounts revealed that the major layer, extending at least 1.2 km from the modern coasts, was probably deposited by arguably the largest storm surge during the last 2000 years, which took place in 1497 AD. These storm deposits were likely formed during inundation of the low-lying coastal plain after major breaching of coastal dunes resulting in tsunami – like flow pattern and thus similar sedimentological effects. A discontinuous sand layer of younger age (18th century) and sharing similar properties to the previous one may be related to “der Seebär” event or another storm surge. The study revealed that the southern Baltic Sea coast may be affected by much greater coastal flooding than known from more recent accounts and observations. Thus, the presented geological record should be taken as an example of a worst-case scenario in coastal zone risk assessment from natural hazards. These events left sedimentary deposits that resemble tsunami deposits. It is likely that, in similar settings where storm surges cause unidirectional inundation of a coastal plain, it may not be possible to establish whether the resulting deposits were laid down from storms or tsunamis.
