enrichment culture and identification of endophytic methanotrophs isolated from peatland plants.aerobic methane-oxidizing bacteria (mob) are an environmentally significant group of microorganisms due to their role in the global carbon cycle. research conducted over the past few decades has increased the interest in discovering novel genera of methane-degrading bacteria, which efficiently utilize methane and decrease the global warming effect. moreover, methanotrophs have more promising applications in environmental bioengineering, biotechnology, and pharmacy. the investigations were undert ...201728275945
pollen dispersal and fruit production in vaccinium oxycoccos and comparison with its sympatric congener v. uliginosum.investigating plant-pollinator interactions and pollen dispersal are particularly relevant for understanding processes ensuring long-term viability of fragmented plant populations. pollen dispersal patterns may vary strongly, even between similar congeneric species, depending on the mating system, pollinator assemblages and floral traits. we investigated pollen dispersal and fruit production in a population of vaccinium oxycoccos, an insect-pollinated shrub, and compared the pollen dispersal pat ...201322823148
global change shifts vegetation and plant-parasite interactions in a boreal mire.the aim of this study was to detect vegetation change and to examine trophic interactions in a sphagnum-dominated mire in response to raised temperature and nitrogen (n) addition. a long-term global-change experiment was established in 1995, with monthly additions of n (30 kg x ha(-1) x yr(-1)) and sulfur (20 kg x ha(-1) x yr(-1)) during the vegetation period. mean air temperature was raised by 3.6 degrees c with warming chambers. vegetation responses were negligible for all treatments for the f ...200717479763
ozone effects on the ultrastructure of peatland plants: sphagnum mosses, vaccinium oxycoccus, andromeda polifolia and eriophorum vaginatum.ozone effects on peatland vegetation are poorly understood. since stress responses are often first visible in cell ultrastructure, electron microscopy was used to assess the sensitivity of common peatland plants to elevated ozone concentrations.200415333464
allozyme evidence for genetic autopolyploidy and high genetic diversity in tetraploid cranberry, vaccinium oxycoccos (ericaceae).polyploidy has been important in the evolution of angiosperms and may significantly affect population genetic diversity and structure. nineteen isoenzyme loci were studied in diploid and tetraploid populations of vaccinium oxycoccos (ericaceae), and the results are compared with data previously reported for the related v. macrocarpon. diploid v. oxycoccos and v. macrocarpon were readily discriminated based on their allozymic variation. no evidence for fixed heterozygosity was found in tetraploid ...200011118425
