Armstrong R.A. (2024): Ecology of Lichens on Rock Surfaces - ,

Rock surfaces are one of the more extreme habitats for the development of a lichen ecosystem. By following the life cycle stages of lichens colonizing rock surfaces, this review discusses the progress made over the last 50 years in understanding the ecology of lichens on rock. First, dispersal, attachment, and establishment of lichens are hazardous processes but nevertheless, colonization of many rock surface appears highly efficient. Second, growth to maturity is influenced by many environmental … URL EndNote PDF Read more...

Adamson C., McCabe S., Warke P.A., McAllister D. & Smith B.J. (2013): The influence of aspect on the biological colonization of stone in Northern Ireland - International Biodeterioration & Biodegradation, 84: 357-366

The rate and type of biological colonization of stone is influenced by a wide array of environmental factors in addition to substrate characteristics. A series of experiments was designed to compare the rate and type of biological colonization of stone at varying locations over a 21-month time period. Exposure trials were set up at nine different sites across Northern Ireland that covered a wide variety of environmental conditions. To determine aspect-related differences in colonization, blocks of … URL EndNote PDF Read more...

Voitk A., Saar I., Burzynski M. & Corriol G. (2024): The Arrhenia peltigerina complex—preliminary report - Botany, 102: 248–267

Phylogenetic study of Arrhenia peltigerina revealed a complex of seven divergent clades. Type specimens of Agaricus peltigerinus and Omphalina cupulatoides fell into separate clades; the latter was recombined as Arrhenia cupulatoides. Four clades were described as new species: Arr. baltica, Arr. fennoscandica, Arr. mohniensis, and Arr. talpoides; the fifth, with only a single specimen, was left formally undescribed. These cryptic species are uncommon——more so in North America than Scandinavia——and … URL EndNote Read more...

Glueck D., Schiefelbein U. & Schubert H. (2024): Ecological impacts of coastal protection on the vegetation of sandy coasts at the German Baltic Sea coast - Coasts, 4(2): 437–453

Sand nourishments and groynes as coastal protection measures (CPM) address similar challenges on sandy coasts but take different approaches: while groynes are intended to reduce alongshore sediment transport and erosion, nourishments add new sediment to the system to compensate for erosion. The aim of this study is to compare the ecological effects of such measures on the vegetation. To this end, nutrient analysis and botanical mappings were carried out on a site with installed groynes, a site where … URL EndNote PDF Read more...

Bell-Doyon P., Mazerolle M.J., Bélanger L., Fenton N.J. & Villarreal A. J.C. (2024): Differential impact of clearcut and insect outbreak on boreal lichens and bryophytes 50 years after disturbance - Biological Conservation, 295: 110672 [8 p.]

Lichens and bryophytes are ubiquitous in terrestrial habitats, sensitive to environmental changes, and they contribute to ecosystem functions and biogeochemical cycles. Intact forest ecosystems host distinct biotic communities that are associated with microhabitat and structural diversity at stand and landscape scales. In the boreal region of eastern Canada, insect outbreaks and clearcutting (the dominant timber harvesting method) are common disturbances. However, while insect outbreaks from native … URL EndNote Read more...

Panov A., Prokushkin A., Korets M., Putilin I., Zrazhevskaya G., Kolosov R. & Bondar M. (2024): Variation in soil CO2 fluxes across land cover mosaic in typical tundra of the Taimyr Peninsula, Siberia - Atmosphere, 15(6): 698 [20 p.]

Increased warming in the Arctic is of great concern. This is particularly due to permafrost degradation, which is expected to accelerate microbial breakdown of soil organic carbon, with its further release into the atmosphere as carbon dioxide (CO2). The fine-scale variability of CO2 fluxes across highly mosaic Arctic tundra landscapes can provide us with insights into the diverse responses of individual plant communities to environmental change. In the paper, we contribute to filling existing gaps … URL EndNote Read more...

Farkas E., Kirika P.M., Szabó K. & Muhoro A.M. (2024): Concentration data of (+)-usnic acid enantiomer from some European and African samples of Flavoparmelia caperata (L.) Hale (Parmeliaceae, lichenised Ascomycota) – results of a preliminary study - Cryptogamie, Mycologie, 45(7): 71–82

The usnic acid, cortical pigment, is generally known to protect lichens from extreme radiation. According to earlier studies, the parmelioid lichen Flavoparmelia caperata (L.) Hale contains (+)-usnic acid. Since the production of lichen secondary metabolites – like other physiological activities – is influenced by environmental conditions, we assumed that macroclimatic differences in temperature, radiation and humidity in European and African habitats resulted in differences in the concentrations … URL EndNote Read more...

Nimis P.L., Pittao E., Caramia M., Pitacco P., Martellos S. & Muggia L. (2024): The ecology of lichenicolous lichens: a case-study in Italy - MycoKeys, 105: 253–266

This paper, with Italy as a case-study, provides a general overview on the ecology of lichenicolous lichens, i.e. those which start their life-cycle on the thallus of other lichens. It aims at testing whether some ecological factors do exert a positive selective pressure on the lichenicolous lifestyle. The incidence of some biological traits (photobionts, growth-forms and reproductive strategies) in lichenicolous and non-lichenicolous lichens was compared, on a set of 3005 infrageneric taxa potentially … URL EndNote PDF Read more...

(2024): Legal boundaries and conservation: The case of Seasonally Dry Forests of the Serra da Bodoquena National Park, Brazil - Acta Botanica Brasilica, 38: e20230010 [11 p.]

The Serra da Bodoquena National Park is an important protected area that promotes the conservation of a threatened ecosystem, the Dry Forest. It comprises two major fragments of predominantly Seasonally Dry Forest vegetation. The two fragments are under different protection schemes because they are considered different biomes. The southern fragment is considered part of the Atlantic Forest biome, and is thus protected by the Atlantic Forest Law, while the northern one is considered part of the Cerrado … URL EndNote Read more...
