Abstract:
ABSTRACTThe chemistry of epiphytic lichens was determined in two Venezuelan cloud forests adjacent to the Caracas Valley at Altos de Pipe and El Avila National Park. This is the second component of a two-part study examining the chemistry of fogs and their effects on sensitive biota in these forests. The widespread lichen Parmotrema madagascariaceum was chosen as an indicator of trace metal input. Background lichen collections and transplant experiments were carried out to evaluate spatial trends in atmospheric depositon of trace metals at different altitudes and exposures of the two montane locations. Elevated concentratons of metals including Pb and Zn were seen in lichen tissue and associated bark. Lead levels in lichens reached 190 μg g-1 dry wt. Lichens transplanted from relatively ‘clean’ to more polluted sites showed significant increases of metals, particularly Pb. Increases of up to 6.3 μg Pb g-1 mo-1 after 6 and 10 months were recorded relative to background and in situ lichen material. In contrast, when lichsens were reciprocally transplanted in nylon net bags from less to more exposed sites there was a significant decrease in Pb and Zn concentrations after 6 and 10 months. With long-term exposure to elevated concentrations of these trace metals epiphytic lichens, as well as other sensitive cloud forest biota, may be at risk of decline.

Abstract:
Seasonal growth increments (%) were measured in the foliose epiphytic lichen Pseudocyphellaria berberina in north-western Patagonia. Growth was determined by measuring increase in weight (expressed as percentage of the original biomass) in transplanted thalli. Transplants were either hung freely from wooden frames or attached to tree trunks in a Nothofagus dombeyi forest and then weighed every three months between January 2001 and April 2003. The influence on growth increment of treatment, donor thallus, temperature, and absolute and relative humidity was analysed. Mean annual growth increment after two years, in both treatments was 12±1·07% (±SE). Growth increment was greatest in winter and lowest in summer; the mean winter growth increment was 6±0·50%, representing half of the annual growth, whereas most of the remaining growth occurred during both spring and autumn. Growth increments were similar for freely-hanging lichens and for the transplants attached to tree trunks. Individual trees had no consistent effect on growth while the donor thallus had a significant effect in the first season which then diminished, indicating acclimation in the transplants. Initial transplant weight had no influence on final cumulative growth, nor was there any consistent correlation between one season and another in the growth of transplants. Both transplantation methods proved to be useful for experiments on the growth of P. berberina.

Abstract:
Urban air pollution has been a major concern due to its impact on global public health. Various techniques for monitoring urban air quality have been developed. However, there is currently a dearth of research on how effective bioaccumulators such as lichen are at monitoring urban air pollution. As a result, the purpose of this research is to investigate the use of U. misaminensis as a biological indicator for biomonitoring urban air quality in Malaysia. Three months were spent exposing lichen samples in three Malaysian cities (Kuala Lumpur, Penang, and Johor Bahru). The trace element content and vitality of the lichens were assessed. The results of this study revealed that U. misaminensis is an effective biological indicator for measuring 25 elements of air pollutants in metropolitan areas. They also revealed that all 25 elements accumulated in the urban area sample were greater than in the control sample. The vitality rate of lichens dropped in the urban area sample when compared with the control sample, indicating that an increase in elements in the air will impact the vitality rate of any biological component. In this study, two arguments are made: (a) Lichen is an excellent biological indicator, particularly for urban air pollutants such as potentially toxic elements; and (b) traffic is the primary contributor to urban air pollution; hence, the local government requires a better plan and design for urban areas to decrease air pollutants build-up.

Abstract:
AbstractLichens were cultured by attaching a thallus fragment to a nylon monofilament loop with silicone sealer. Two effective methods for adjusting lichen mass to a standard moisture content were developed (the ‘reference-sample’ and ‘sacrificial’ methods). These corrections for moisture content allow detection of very small changes in dry mass without having to oven dry (and kill) all transplants. Average annual biomass growth rates for non-fragmenting species were typically between 5 and 30%. Annual biomass growth rates of healthy, vigorous individuals, as indicated by the 75th percentile, were mostly between 10 and 40%. Alectoria sarmentosa was prone to fragmentation despite the maintenance of healthy thalli. The other species can be ranked by biomass growth rates as follows: Evernia prunastri> Lobaria pulmonaria=Usnea longissima> Pseudocyphellaria rainierensis=Lobaria oregano.

Abstract:
To investigate the factors responsible for limited lichen recolonization on oak with declining SO2 concentrations, Parmelia caperata (L.) Ach. and Parmelia saxatilis (L.) Ach. were transplanted to five stations along a transect running from central London (U.K.) into the surrounding countryside. Healthy thalli were transplanted onto young and mature Quercus robur L. (pedunculate oak) and Betula pendula Roth (silver birch), and some were moved with their original bark attached to investigate the importance of bark acidification. Relative growth rates and visible injury were monitored over 2 years, along with concentrations of atmospheric SO2 and NO2, measured using diffusion tube samplers and bark chemistry. SO2 concentrations were low in central London in comparison with the situation in previous decades, but they remain sufficiently high to harm the most sensitive lichens. NO2 concentrations increased sharply on approaching London, and levels were higher in winter than in summer. Bark pH was lower in mature oak than in birch or young oak at the two innermost stations, and levels of bark Mg also declined in London. Transplants of P. caperata survived on birch and young oak at all transect stations except Hyde Park, whereas P. saxatilis failed to grow over a wider range of the transect stations. We conclude that modest SO2 levels, interacting with low bark pH, still inhibit recolonization of oaks by P. caperata in central London. Parmelia saxatilis, in addition, appears to be limited by another factor such as the high NO2 concentrations that now characterize urban and suburban London, rather than through an inherently poor dispersal potential.Key words: atmospheric pollution, bark acidification, epiphytic lichens, NO2, recolonization, SO2.

Abstract:
The development of habitat restoration techniques for restoring critical woodland caribou (Rangifer tarandus caribou) winter habitat will play an important role in meeting the management thresholds in woodland caribou recovery plans. The goal is to restore disturbed environments within critical winter habitat for the declining woodland caribou. Woodland caribou are diet specialists, utilizing lichen-rich habitat for forage during winter months. Cladonia sub-genus Cladina is the most frequently eaten species during this time. Herein, we provide: 1) A review of previously used methods for transplanting Cladonia sub-genus Cladina and their feasibility in restoring woodland caribou winter habitat; 2) A stepby- step protocol on how to carry out a terrestrial lichen transplant program (using Cladonia sub-genus Cladina and C. uncialis); and, 3) An evaluation of our protocol through the establishment of a case study in northern British Columbia. Our results indicate that transplanting C. sub-genus Cladina fragments is the most efficient technique for transplanting terrestrial lichen communities, but transplanting lichen ‘patches’ or ‘mats’ may also be effective.

Abstract:
The transplantation of genus Cladonia terricolous lichens on Polyporales parasitic xylophagous fungi was attempted. Three species of Cladonia (C. pyxidata, C. rangiformis, C. foliacea) have been moved (translocated) from Livorno hill woods (Tuscany, Italy) to some public Livorno parks which suffer by an excessive anthropization. After a short period (a week) of adaptation to the new environment we transplanted thirteen specimens of Cladonia lichens on four different species of Polyporales fungi (Fomitopis betulina, Phellinus torulosus, Stereum hirsutum and Ganoderma applanatum) identified on the trees of the parks. The transplants obtained good engraftment and every periodic qualitative control showed a persistent photosynthetic activity even eight months after the start. Only one transplant (on Ganoderma applanatum) failed due by the toxicity of a secretion after incision. These observations lead us to consider those experiments as a demonstration of the compatibility of the implied tissues on transplantation and also allow us to introduce the difference of the term transplantation (the insert of an organism to another) from the often-confused translocation (relocation of an organism in different habitat). Future checks will indicate how and for how long this artificial association complex might persist.

Abstract:
The arboreal forage lichen Bryoria fremontii (Tuck.) Brodo & D.Hawksw. appears sensitive to conditions of prolonged hydration in wet forests of British Columbia. I estimated the abundance of this lichen in mixed-conifer forest canopy in the contrasting Mediterranean climate of the southern Sierra Nevada in relationship to the vertical gradient of vapor pressure deficit. Abundance was estimated by biomass in 5 m strata from the ground to the tops of 50 trees. Transplants of Bryoria thalli were installed in 18 fir trees for 1 year to assess their growth relative to distance from perennial streams. VPD generally increased with height, being significantly greater at 45 m than 5 m. Bryoria biomass averaged across tree heights was estimated as 15.9, 0.60, 0.15, 0.25, and 0.19 g·m–1 in red fir (Abies magnifica A.Murray), white fir (Abies concolor (Gordon & Glend.) Hildebr. var. lowiana (Gordon) Lemmon), incense cedar (Calocedrus decurrens (Torr.) Florin), Jeffrey pine (Pinus jeffreyi Balf.), and sugar pine (Pinus lambertiana Douglas), respectively. Transplant growth was significantly greater in trees <25 m from water (11.4%) than in trees >25 m from water (9.7%). Bryoria had strong positive associations with red fir, proximity to streams, and decreasing VPD. The sensitivity of Bryoria to prolonged hydration does not appear to be important in this climate characterized by extended summer dryness.

Abstract:
This project is a pilot study to assess the viability of transplantation as a technique to establish reindeer lichens on reclaimed areas of oil sands surface mines in the Athabasca region of Alberta. There were two components to this study: a) a lichen transplant trial, where I investigated which commonly available substrates found in reclaimed forest sites would promote the best lichen fragment survival and vigour for a lichen ‘seeding’ program; and b) a diversity assessment of the reclaimed site to compare the existing cryptogam community with the expected community for the target ecosite based on published descriptions from the surrounding native forests and documented chronosequences for terrestrial lichen communities. In July 2009, Cladonia mitis was transplanted into 54 plots on three sites that were planted with jack pine or spruce 12 or 24 years ago, respectively, on the Suncor Millenium/Steepbank Mine (Suncor Mine). This trial was designed to investigate possible short-term indicators of successful lichen establishment and the effect of substrate (moss, litter, or soil) on the establishment of transplanted lichen thallus fragments. The indicators of lichen establishment evaluated were vigour, movement from plots, photographic areal cover, and microscopic growth (hyphal growth, annual growth and lateral branching). After two growing seasons, the effect of substrate on lichen transplant survival varied by site; there was no significant difference in lichen fragment retention in plots by substrate on the 24-year old sites, but median fragment retention was significantly higher on moss and litter substrates than soil on the 12-year old site. There was also no significant difference in fragment vigour between substrates on each site, except on the south-facing 24-year-old forest site where average vigour was significantly higher on moss plots than on soil plots. Photographic areal measurement is not recommended as a short-term lichen establishment monitoring tool for transplanted fragments based on the difficulties encountered using the method for this trial. Forty-one percent of the fragments collected for microscopic assessment after the first growing season had grown hyphae, 23 percent of the fragments collected during September 2009 and September 2010 had formed apothecia, and 31 percent of the fragments collected in September 2010 had grown lateral branches. The results of the biodiversity assessment were compared with the successional communities previously described for spruce- and pine-lichen boreal forests. There were no lichens found on the 12-year-old site, though the cup lichens were common to abundant on the 24-year-old sites, which is consistent with the cryptogammic community expected for a regenerating natural site of that age. Cladonia mitis was also present but rare to uncommon on the 24-year-old site, while Cladonia stellaris, Cladonia rangiferina and Cladonia stygia that, together with C. mitis, are indicative of the al and c1 ecosites of the Central Mixedwood Boreal forest, were not present.

Abstract:
Ein Jahrhundert österreichische Bundesverfassung im nationalen und internationalen Kontext Das Jubiläumsjahr der österreichischen Bundesverfassung gibt Anlass, die Entwicklung, aber auch Gegenwart und Zukunft des Bundes-Verfassungsgesetzes (B-VG) im Lichte des europäischen und globalen Konstitutionalismus zu erörtern. Das B-VG als die "Stammurkunde" der österreichischen Bundesverfassung feiert am 1. Oktober 2020 seinen 100. Geburtstag. Damit ist sie eines der ältesten in Kontinuität stehenden Verfassungsdokumente Europas. Es hat vor allem mit der Schöpfung des spezialisierten Verfassungsgerichtshofes eine Institution hervorgebracht, die von einer Mehrheit der Verfassungen weltweit als legal transplant übernommen wurde und eine zentrale Rolle für die Aufrechterhaltung liberaler Demokratien spielt. Die Beiträge in diesem Band erstrecken sich über Verfassungsfunktionen und -konzepte im nationalen und internationalen Zusammenhang, Verfassungsänderungen und deren Schranken, die Rolle des Verfassungsgerichtshofs und die Auslegung der Verfassung bis hin zu Zusammenspiel und Interdependenzen von Verfassungen im europäischen Mehrebenensystem gerade im Hinblick auf Grundrechte.
