Ismailov A.B. & Urbanavichus G.P. (2024): Leptochidium albociliatum (lichenized Ascomycota), the first record of the species and the genus for the Caucasus, Ботанический журнал [Botanicheskii Zhurnal], 109(10): 1056–1060

None species of the genus Leptochidium was previously known within the Caucasus. In the mountain pine forest of Dagestan on siliceous rock outcrops we found a first species of this genus – Leptochidium albociliatum. In the lichen flora of Russia, L. albociliatum was known only from northern and arctic regions of the European part with the latest record dates back more than 100 years ago. Description of the genus Leptochidium and the species L. albociliatum with information of its habitat, distribution … URL EN Read more...

Martínez Y.A.G., Abarca G.P.H., Garza R.V. & Raymundo T. (2021): First record of Mycoporum buckii (Dothideomycetes, Pleosporales) in Mexico [ Primer registro de Mycoporum buckii (Dothideomycetes, Pleosporales) en México], Acta Botanica Mexicana, 128: e1802

Background and Aims: The genus Mycoporum of the class Dothideomycetes of the phylum Ascomycota is characterised by ascostromata with scattered, aggregated locules without a wall of their own, bitunicate asci with a short pedicel, as well as ellipsoidal, fusiform to clavate ascospores with broader upper hemispores, and a variable number of septa. The objective of this study is to report Mycoporum buckii for the first time in Mexico. Methods: The specimens were collected on Rhizophora mangle bark in … URL EN Read more...

Min E., Wilcots M.E., Naeem S., Gough L., McLaren J.R., Rowe R.J., Rastetter E.B., Boelman N.T. & Griffin K.L. (2021): Herbivore absence can shift dry heath tundra from carbon source to sink during peak growing season, Environmental Research Letters, 16(2): 024027

In arctic tundra, large and small mammalian herbivores have substantial impacts on the vegetation community and consequently can affect the magnitude of carbon cycling. However, herbivores are often absent from modern carbon cycle models, partly because relatively few field studies focus on herbivore impacts on carbon cycling. Our objectives were to quantify the impact of 21 years of large herbivore and large and small herbivore exclusion on carbon cycling during peak growing season in a dry heath … URL EN Read more...

Putzke J., Schünemann A.L. & Pereira A.B. (2021): Growth rate and behavior over 20 years in the crustose lichen Haematomma erythromma at Elephant Island, Antarctica, Oecologia Australis, 25(1): 103-116

Antarctica is one of the most extreme environments on the planet considering the climatic conditions. This greatly limits the development of plants, and is reflected in slow growth, especially in the lichens present in this environment. Haematomma erythromma is a nitrophile lichen easily identifiable by its color and was the species chosen to evaluate growth in Antarctica. Using a plastic sheet, squares of 20 x 20 cm were placed on eight different rocks with crustose lichen communities and the species … URL EN Read more...

Sobakin P.I., Zakharov E.S. & Safronov V.M. (2021): Global 137Cs pollution of the Territory of Yakutia and content in the feed and tissue of wild game, Biology Bulletin, 48: 506-513

Data on the concentration of 137Cs is obtained from soils, food plants, and muscle tissue of seven species of game animals (wild reindeer, elk, roe deer, musk deer, bighorn sheep, white hare, and brown bear) in the tundra and taiga zones of Yakutia. It has been shown that reindeer and musk deer are consumers of bushy lichens, are characterized by a relatively high content of 137Cs (up to 51.6–75.1 Bq/kg), and can be a source of its intake into the organism of the next level consumer—the brown … URL EN Read more...

Wang Y., Zhang H., Liu X., Liu X. & Song W. (2021): Fungal communities in the biofilms colonizing the basalt sculptures of the Leizhou Stone Dogs and assessment of a conservation measure, Heritage Science, 9(1): 36

The Leizhou Peninsula in China is very famous for its unique folk art creation, especially for the stonework, like the basalt sculptures of the Leizhou Stone Dogs, which have a history of more than two thousand years. Since these sculptures are usually exposed outdoors, many of them are suffering from severe damage by lichen and fungi. To protect them from microbial attack, we determined fungal communities in the biofilms colonizing the stone dogs and explored an effective conservation measure. Specifically, … URL EN Read more...

Halbwachs H., Harper C.J. & Krings M. (2021): Fossil Ascomycota and Basidiomycota, with notes on fossil lichens and nematophytes, Encyclopedia of Mycology, 1: 378-395

The fossil record contains abundant evidence of the hyperdiverse kingdom Fungi. Macrofungi (Ascomycota, Basidiomycota) enter this record in the Paleozoic, some 360–540 myr ago. Common modes of preservation of macrofungi include impression, compression, petrifaction, and permineralization; delicate mushrooms may also occur as amber inclusions. Fossils have contributed greatly to our understanding of the roles fungi played in past ecosystems, including the various interactions they formed with other … URL EN Read more...

Söderström L. (1988): The occurrence of epixylic bryophyte and lichen species in an old natural and a managed forest stand in Northeast Sweden, Biological Conservation, 45(3): 169–178

An old natural spruce stand and a managed spruce stand were compared with regard to occurrence of epixylic bryophyte and lichen species and amount of decaying wood in different size classes and decay stages. Epixylic hepatics occurred more frequently in the natural stand while Cladonia species were predominant in the managed stand. This difference is explained by differences in humidity regimes, with the managed stand exposed to drought more often than the natural stand. The managed stand also had … URL EN Read more...

Heidrich L., Bae S., Levick S., Seibold S., Weisser W., Krzystek P., Magdon P., Nauss T., Schall P., Serebryanyk A., Wöllauer S., Ammer C., Bässler C., Doerfler I., Fischer M., Gossner M.M., Heurich M., Hothorn T., Jung K., Kreft H., Schulze E.-D., Simons N., Thorn S. & Müller J. (2020): Heterogeneity–diversity relationships differ between and within trophic levels in temperate forests, Nature Ecology and Evolution, 4(9): 1204–1212

The habitat heterogeneity hypothesis predicts that biodiversity increases with increasing habitat heterogeneity due to greater niche dimensionality. However, recent studies have reported that richness can decrease with high heterogeneity due to stochastic extinctions, creating trade-offs between area and heterogeneity. This suggests that greater complexity in heterogeneity–diversity relationships (HDRs) may exist, with potential for group-specific responses to different facets of heterogeneity … URL EN Read more...

Dynesius M. & Zinko U. (2006): Species richness correlations among primary producers in boreal forests, Diversity and Distributions, 12(6): 703–713

Close correlations in species numbers may make it possible to indirectly assess the species richness of difficult taxonomic groups by investigating indicator groups, for which data are more easily collected. We asked if species numbers correlate among the four dominating groups of primary producers in boreal forests (liverworts, macrolichens, mosses, and vascular plants) and if substrate affiliation of species (ground vs. other substrates), sample plot size (0.01–1000 m2), and stand age (young … URL EN Read more...
