The morphology and anatomy of the monotypic genus Trizeuxis make this taxon almost impossible to recognize in fossil material and hereby difficult object of historical geographic studies. To estimate the distribution of potential refugia during the last glacial maximum and migration routes for Trizeuxis the ecological niche modeling was performed. The potential niche modeling was done using maximum entropy method implemented in Maxent application based on the species presence-only observations. As input data climatic variables and the digital elevation model were used. Two models of suitable glacial habitats distribution were prepared – for the studied species and for its host. The compiled map of the suitable habitats distribution of T. falcata and P. guajava during the last glacial maximum (LGM) indicate two possible refugia for the studied orchid genus. The first one was located in the Madre de Dios region and the other one in the Mosquito Coast. The models suggest the existence of two migration routes of Trizeuxis species. The results indicate that the ecological niche modeling (ENM) is a useful tool for analyzing not only the possible past distribution of the species, but may be also applied to determine the migration routes of the organisms not found in the fossil material.

Oznaczono stężenie rtęci ogółem w próbkach epifitycznego porostu pustułka pęcherzykowata zebranego z sosny, jałowca, lipy, olszy, leszczyny, dębu, brzozy i świerka koło miejscowości Łuby w Borach Tucholskich w lipcu 1994 r. Zbadano zbieżność stężeń rtęci w piesze porostu w zależności od gatunku forofitu. Rtęć oznaczono techniką zimnych par bezpłomieniowej spektrometrii absorpcji atomowej (CV-AAS) po zmineralizowaniu próbek metodą mokrą ze stężonym roztworem kwasu azotowego.

Total mercury concentrations were determined in lichen Hypogymnia physodes collected from eight phorophite species at a selected area of the Tucholskie Forests in 1994. Mean mercury concentrations of H. physodes ranged from 0.15 ± 0.03 to 0.23 ± 0.02 µg/g dry weight (the total range was from 0.11 to 0.24 µg/g dry wt.). The samples of H. physodes from pine and juniper had higher mercury concentrations (p > 0.001) than those collected from limetree, alder, hazel, oak, birch or spruce. The concentrations of mercury found in H. physodes from Tucholskie Forests are in the range of the backround levels set for that species in a former Chechoslovakia and Finland.

Oznaczono stężenie 44 pierwiastków (Na, Mg, Al, Si, P, K, Ca, U, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Tl, Bi, Pb, Ai, Rb, Sr, Y, Ag, Cd, Sn, Sb, Cs, Ba, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Th i U) w piesze epifitycznego porostu pustułka pęcherzykowata zebranego z ośmiu różnych forofitów (sosna, jałowiec, lipa, olsza, leszczyna, dąb, brzoza i świerk) na malej powierzchni lasu koło miejscowości Łuby w Borach Tucholskich w lipcu 1994 r. W analizie zastosowano technikę podwójnie zogniskowanej, wysokorozdzielczej spektrometrii mas z wzbudzeniem w źródłach (double focused HR-ICP-MS), z nebulizerem ultradźwiękowym oraz emisyjnej spektroskopii atomowej ze wzbudzeniem w źródłach (ICP-AES). Wzorcem wewnętrznym byl ind (In). Analizowano zbieżność stężeń poszczególnych pierwiastków w piesze porostu w zależności od gatunku forofitu.

Sodium, potassium, calcium, magnesium, aluminium, silicon, phosphorus, vanadium, chromium, manganese, cobalt, nickel, copper, zinc, gallium, arsenic, rubidium, strontium, yttrium, silver, cadmium, tin, antimony, caesium, barium, lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, thallium, lead, bismuth, thorium and uranium concentrations were determined in lichen Hypogymnia physodes overgrowing eight phorophite species and collected at a selected areas of the Tucholskie Forests in 1994. The method of measurement was double focused inductively coupled high resolution mass spectrometry (HR-ICP-MS) and inductively coupled plasma atomic emission spectroscopy (ICP-AES) after wet digestion of the sample with concentrated nitric acid in Teflon vessels. The concentrations of Al, Si, V, Cr, Ni, Cu, Ga, As, Rb, Sb, Cs, Gd, Er, Tm, Lu, Bi and U in thallus of Hypogymnia physodes were found to be independent of the substrate species. Thallus of Hypogymnia physodes collected from pine, and in some cases also from juniper and limetree contained lower concentrations of Mg, P, Ca, V, Cr, Mn, Co, Zn, Sr, Y, Ag, Cd, Ba, La, Ce, Nd, Sm, Tb, Dy, Ho, Yb, Tl and Pb than samples collected from alder, hazel, oak, birch or spruce, while for Th and Fe higher concentrations were found for pine than other substrates.
