Abstract:

Lichens are symbiotic organisms between fungi and algae. In Indonesia, lichen inventory research is very limited. Several Lichen families have entered critical levels such as Lobariaceae. The purpose of this study was to: record and collect the Lobariaceae family as a rare lichen, analyze population data of the Lobariaceae family, growth percentage and development of Lobariaceae family transplants. This research method used exploration with calculations based on the surface area of tree trunks, the number and coverage of thallus, and thallus coverage per square meter for each tree. The resul

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 l

Abstract:

Anthropogenic microfibers (mfs) are synthetic particles composed of cellulose (cotton, rayon, acetate, etc.) or petrochemical-based polymers (i.e., microplastics—MPs) that are less than 5 mm in length. The accumulation of mfs, including MPs, in the moss Hypnum cupressiforme and the lichen Pseudevernia furfuracea was compared in a transplant experiment lasting 6 weeks. We also tested the effects of the bag used for transplants on the accumulation of mfs. Anthropogenic particles trapped by both biomonitors were mostly filamentous (99% mfs), and their number was overall higher in the moss (mean ±

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.

The influence on growth increment of treatment, donor thallus, temperature, and absolute and relative humidity was analysed. Mean annual growth increment

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

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,

Abstract:

High-irradiance damage in two epiphytic lichens was recorded as reduction in predawn photosystem II quantum yield (Fv /Fm) measured at the end of a night with full hydration. Measurements were repeated during a 29-day transplantation in early summer at defined aspects (north, east, south, west, perpendicular to the sun at noon, and shade) in an open site at 60°N. These treatments included the contrasts that remaining lichens adjacent to clear-cut areas could experience subsequent to logging. The Fv /Fm values declined linearly with the mean irradiance during the previous day, with the old-fore

Abstract:

Heavy metals are major pollutants in tourist cities due to transportation and urbanization. This study aimed to assess heavy metal concentrations using transplanted lichen in tourist cities. The project was conducted in Malacca, Malaysia, using transplanted Usnea misaminensis lichen at ten sampling stations. After one month, these lichen samples were collected and heavy metal analysis was carried out in a lab using ICP-MS. Other factors, such as the number of vehicles, temperature, relative humidity, and wind speed, were also recorded. The results indicated that the heavy metal concentrations

AbstractThe lichen Usnea longissima was used to examine how distance from forest edge and edge contrast influence growth of pendulous lichens. Thalli of two sizes (12 and 27 cm) were transplanted to the lower canopy of old Picea abies forest at 5, 25 and 100 m distance from cutovers. Sites represented three levels of edge contrast: high (clear-cut), intermediate (3 m tall saplings) and low (6–7 m tall young forest). Lichen growth was assessed as annual length and weight gain. Growth rates of intact thalli were size-dependent, with both growth variables being higher in long than in short thalli

Several higher plant species and epiphytic lichen <em>Hypogymnia physodes</em> (L.) Nyl. were examined in the vicinity of a copper smelter. The investigations included field experiments. Ecological surveys of some biotests and bioreactions using exposure of higher plants and transplanted lichens were critically appraised. Such basic processes of plants as photosynthesis and respiration, as well as the quantitative composition of chlorophyll pigments were used as biotests. The results indicate that the photosynthesis intensity is the most useful measure for the estimation of the eff

Abstract:

Monitoring atmospheric pollution in urban areas is challenging because pollutant deposition occurs at short distances, requiring a large amount of sampling and analysis to characterize it. Ecological indicators can help overcome this problem, allowing us to select sites with the highest deposition of pollutants from the atmosphere. Nevertheless, a major gap is the temporal characterization of the accumulation rate of magnetic particles in ecological indicators, which is critical to understand if the bioaccumulation process is linear or if saturation occurs. To overcome this problem, Parmotrema

Topical corticosteroids are the mainstay of skin-directed therapy for cutaneous cGvHD but are associated with significant side effects, and may incompletely treat cutaneous cGvHD thereby prompting the use of systemic therapies. Methods: We conducted a single-center, phase 2 prospective, randomized, double-blind trial evaluating the efficacy and safety of ruxolitinib 1.5% cream in patie

During autumn 2017, lichens (Evernia prunastri) were exposed for two months indoors and outdoors in public (schools) and private (dwellings) environments, in both rural and urban areas of Slovakia. The bioaccumulation of selected elements and the physiological status of the samples were considered. The content of heavy metals increased in samples exposed outdoors for 11 out of 12 elements (Al, As, Cd, Cr, C

In animal models acute GVHD (aGVHD) is associated with increased neovascularization and number of circulating endothelial cells (CECs), while patients with sclerodermatous chronic GVHD (cGVHD) show a significant decrease in the number of circulating endothelial progenitor cells (EPCs) in peripheral blood as compared to patients with non sclerodermatous cGVHD or controls.

Abstract:

Pollutants in the air and heavy metals are regarded as significant contributors to environmental problems. These environmental issues have a wide range of consequences for living organisms. Heavy metals and contaminants have the potential to alter the makeup and flexibility of cellular frameworks, preventing plant and lichen species from absorbing water and nutrients. Lichen thalli can absorb heavy metals through their cell walls. Lichens are more susceptible to environmental stress than other vascular and non-vascular plants. The goal of this research was to find out the levels of air polluti

The species,Alectoria ochroleuca,Flavocetraria nivalis,Cladonia mitisandCetrariella delisei, are associated with increasing snow depth, respectively.
