Akujärvi A., Nirhamo A., Heikkinen R.K., Pykälä J., Saikkonen O., Green T., Peltoniemi M. & Mäkelä A. (2026): The relationship between tree carbon dynamics and the occurrences of epiphytes of conservation concern in boreal unmanaged forests, European Journal of Forest Research, 145: 30 [16 p.]

The loss of pristine forest landscapes due to intensive management has altered forest carbon dynamics and caused a decline in biodiversity. The carbon balance of unmanaged forests is insufficiently known due to a lack of repeated measurements. Moreover, the links between the conservation of threatened species and forest carbon dynamics are poorly explored. We examined the carbon balance of boreal unmanaged forests based on three repeated tree surveys conducted in 27 unmanaged Finnish coniferous-dominated … Read more...

Økland T., Rydgren K., Økland R.H., Storaunet K.O. & Rolstad J. (2003): Variation in environmental conditions, understorey species number, abundance and composition among natural and managed Picea abies forest stands, Forest Ecology and Management, 177: 17–37

We studied four south-facing and three north-facing boreal spruce forest stands (ca. 0.1 ha each) in SE Norway with the aim of testing the hypothesis that former logging has long-term effects on boreal forest-floor vegetation. The stand series comprised unlogged natural forests and forests that were selectively or clear cut 60–70 years prior to our study. Each stand was described with respect to history of forestry impact and tree-stand structure. Environmental, species number, species abundance … Read more...

Thorn S., Bässler C., Bernhardt-Römermann M., Cadotte M., Heibl C., Schäfer H., Seibold S. & Müller J. (2016): Changes in the dominant assembly mechanism drive species loss caused by declining resources, Ecology Letters, 19: 163–170

The species–energy hypothesis predicts that more productive areas support higher species richness. Conversely, when resources are reduced, species richness is reduced. Empirical tests of whether extinctions are predominantly caused by environmental constraints or competitive exclusion are lacking. We experimentally reduced dead wood to c. 15% of the initial amount after a major windstorm and examined changes in assembly mechanisms by combining trait-based and evolutionary species dissimilarities … Read more...

Miller J.E.D., Villella J., Kofranek D. & Clark J. (2026): Recreational trails reduce lichen and bryophyte diversity and the occurrence of rare species, Journal of Applied Ecology, 63(2): e70298 [13 p.]

Increasing recreational use of natural areas may pose a threat to biodiversity, particularly in sensitive high-elevation ecosystems. Lichens and bryophytes (collectively termed cryptogams here) contribute substantially to biodiversity in almost all terrestrial ecosystems, but their response to disturbance from recreation has rarely been studied. We inventoried lichen and bryophyte communities and analysed impacts of disturbance and environmental variables at four study areas in Mount Rainier National … Read more...

Donis J., Pentjuša L., Gerra-Inohosa L., Zdors L., Bambe B., Meiere D., Pilate D., Straupe I., Jansons A. & Libiete Z. (2025): Conservation values in set-aside black alder forests adjacent to managed stands: short-term changes, iForest, 18: 319–326

Forests dominated by black alder (Alnus glutinosa) potentially support habitats with high biological diversity, including rare and endangered species with specific demands for the habitat. However, the knowledge on the response of set aside black alder forests to adjacent stand management is still insufficient for planning sustainable forest management and requires additional studies on the dynamics of complex organism groups. We conducted repeated inventories of ground vegetation, epiphytic lichens, … Read more...

(2018): The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests, Journal of Applied Ecology, 55: 267–278

For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged (UEA) management over more traditional coarse-grained even-aged (EA) management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial … Read more...

Myllys L., Svensson M., Kantvilas G., Sérusiaux E., van den Boom P., Aptroot A., Cezanne R., Eichler M., Pino-Bodas R., Printzen C., Pykälä J., Thor G., Westberg M., Weber L. & Kantelinen A. (2025): The first comprehensive multilocus phylogeny of the lichenized genus Micarea (Ectolechiaceae, Ascomycota), Taxon, 75(1): e70087 [35 p.]

Micarea is a crustose cosmopolitan lichen genus that belongs to the euascomycete class Lecanoromycetes. Recent molecular phylogenies on the genus based on one to three loci have mostly focused on Micarea s.str., including the type species M. prasina, and suggested that Micarea s.l. is paraphyletic. The remainder of the genus remains more poorly studied, and infrageneric delimitations and the phylogenetic position of many taxa are still insufficiently known. The aim of this study is to generate, for … Read more...

Kaufmann S., Delp M., Heinze D., Kreimeyer L., Rosenbach M. & Hauck M. (2026): Tree species choice by forest management and biodiversity: Replacing Abies alba by Picea abies and Pseudotsuga menziesii drives epiphytes to higher elevations, Forest Ecology and Management, 605: 123501 [12 p.]

Pseudotsuga menziesii is considered as a replacement tree species for the drought-sensitive Picea abies in Central European forests, which was often cultivated outside its natural elevational distribution range. Hence, the natural tree species composition at lower elevations was replaced mostly by Picea abies, which in turn is partly displaced by Pseudotsuga menziesii. How epiphytic bryophytes and lichens respond to such alterations of the natural tree species composition has been only insufficiently … Read more...

Santi E., Maccherini S., Rocchini D., Bonini I., Brunialti G., Favilli L., Perini C., Pezzo F., Piazzini S., Rota E., Salerni E. & Chiarucci A. (2010): Simple to sample: Vascular plants as surrogate group in a nature reserve, Journal for Nature Conservation, 18(1): 2–11

One of the basic tools to quantify biodiversity is based on the use of surrogate species. Such groups of species are easily assessed and may reflect the diversity of other important and less easily detectable taxa (cross-taxon surrogacy). Among these key groups of species, the vascular plant flora has great potential in determining diversity of other groups, since in terrestrial ecosystems it constitutes the bulk of total biomass and provides the physical structure for other organisms. The cross-taxon … Read more...
