Stable nitrogen isotopes (δ15N) in thalli of the lichen Hypogymnia physodes along a altitudinal gradient in the Khangai Plateau, Mongolia

Carbon, Nitrogen and Sulphur concentration and δ13C, δ15N values in Hypogymnia physodes within the montane area – preliminary data

“…Moreover, any correlation between the analyzed factors and height was not found. Nevertheless, this study yielded the information that in due course of time, the SO 2 and SO 4 2ion decreased, which is reflected in decreased %S in lichens. For sampling points located within Karpacz city (sampling points No.…”

“…Numerous lichen species may be classified as effective organisms able to absorb and accumulate atmospheric trace element pollutants from ambient air and rain due to their structure and slow growth (van Dobben et al, 2001; Gombert et al, 2003). Similar to other bioindicators, lichens are used for determining the degree of environment contamination by heavy metals (Conti and Cecchetti, 2001;Jóźwiak, 2007;Bosch-Roig et al, 2013), sulphur (Manninen et al, 1991;Wadleigh et al, 1996;Wadleigh, 2003), nitrogen (Fuentes and Rowe, 1998;Gombert et al, 2003;) Biazrov, 2012a). For this study, the area of Karpacz city (15°44'E, 50°47'N), which is located in the closest vicinity of Karkonoski National Park, was chosen.…”

“…Between 2006 and 2011, the yearly SO 2 concentration in atmosphere measured in the urban monitoring points in Wrocław decreased from ca. 15 mg·m -3 to 6 mg·m -3 , whereas SO4 2ion dissolved in precipitation for the complete Lower Silesia Voivodeship decreased from 24.42 kg/ ha·year to 14.71 kg/ha·year (VIEP, Report, 2011). The nitrogen concentration in lichen Hypogymnia physodes noted in literature for other localization ranged from 0.49 to 0.71%(Laxton et al, 2010), from 0.6 to 1.1% (Biazarov, 2012a) and from 0.75 to 2.60%(Poikolainen et al, 1998), whereas the results obtained in this study varied from 0.86 to 1.85%.…”

The coupled study of metal concentrations and electron paramagnetic resonance (EPR) of lichens (Hypogymnia physodes) from the Świętokrzyski National Park—environmental implications

“…Lichen investigated in this study were from the Hypogymnia physodes (L.) Nyl. species, which is a lichenized fungus, classified as a chlorolichen (Biazrov 2012 ), with Trebouxia phycobiont (Cuna et al 2007 ). The multifoliose thallus is forming a rosette with inflated lobes (mostly 3–7 cm in diameter; Bystrek 1997 ; Biazrov 2012 ).…”

“…species, which is a lichenized fungus, classified as a chlorolichen (Biazrov 2012 ), with Trebouxia phycobiont (Cuna et al 2007 ). The multifoliose thallus is forming a rosette with inflated lobes (mostly 3–7 cm in diameter; Bystrek 1997 ; Biazrov 2012 ). The smooth and shining lobes are green-gray or gray on the top cortex, black on the bottom cortex, and light brown on the edges.…”
