Cetrelia cetrarioides, C. olivetorum and C. monachorum were confirmed to occur in the country. The last taxon is new to Latvia. Distribution maps and habitat preferences of all three species in Latvia were presented, and their conservation status was discussed.

In total, 60 species of lichenized fungi, six non-lichenized saprophytic fungi and three non-lichenized fungi are reported as new for Gauja National Park. Among them, ten species are new to Latvia. Data on habitats, substrates, main characteristics and distribution in the neighbouring countries to Latvia are provided. The total number of lichenized and closely related fungi for the Gauja National Park is 346.

However, data about the environmental demands of rare epiphytic bryophytes and lichens in boreo-nemoral forest landscapes are not complete. In this study, we focused on finding the main environmental predictors influencing the occurrence of three red-listed epiphytic bryophytes and three red-listed epiphytic lichens in the Latvian boreo-nemoral forest landscape. We obtained the records of species from the Natural Data Management System OZOLS database, which is a national information system on all rare taxa. We analyzed the occurrence of species in relation to forest stand age and area, forest type, heterogeneity and tree bark pH class. We found that selected red-listed bryophyte and lichen occurrence was mainly influenced by forest stand age and area. However, each of the red-listed epiphytic bryophyte and lichen has their own ecological demands in the boreo-nemoral landscape.

The most remarkable findings of lichenized and lichenicolous fungi are recorded herewith, including nine new species (of them two lichenicolous), and one new intraspecific taxon for the country. Full species lists are provided for two notable locations, sandstone outcrop at the river Pärnu and an oak woodland in the Naissoo Nature Reserve, for which no previous data were available, to illustrate the importance of collective survey effort. 2019. a augustis toimus Eestis korraline, iga kahe aasta järel korraldatav Põhjamaade Lihhenoloogide Ühingu kokkutulek ja ekskursioon. Artiklis anname ülevaate huvitavatest lihheniseerunud ja lihhenikoolsete liikide leidudest, sealhulgas üheksa (neist kahe lihhenikoolse) liigi esmaleiust Eestis ja ühe liigisisese taksoni esmaleiust.

There is a need for alternative methods to reduce the palatability of crop plants. Chemical properties of secondary compounds from lichens influence the feeding behaviour of slugs. Liquid extracts of three lichen species, Cladonia rangiferina (L.) F.H. Wigg., Cladonia stellaris (Opiz) Pouzar & Vězda and Pseudevernia furfuracea (L.) Zopf, were applied to three different crops and tested for their antifeedant properties against an important agricultural pest, the Spanish slug Arion vulgaris (Moquin-Tandon, 1855). All three extracts had specific activity, showing a decrease in grazing intensity and also slug weight loss after feeding on treated food. Slugs significantly gained weight after feeding under control condition; however, they did not gain weight when fed on extract-treated food. The most effective extract was ...

Data on substratum geology, accompanying species, microhabitat and distribution in neighbouring to Latvia countries are provided.
