Are cows pickier than goats? Linnaeus’s innovative large-scale feeding experiment Open
In 1749, Linnaeus published Pan Svecicus, a thesis that was defended by his student Nils Hesselgren. The thesis describes food preference trials in cows, goats, sheep, horses, and pigs, and includes 2325 tests with 643 plant species. The d…

Vegetation dynamics 1946–2018 in an old‐growth conifer forest Open
We analysed ground vegetation in 250 plots in 2018 in the old‐growth Picea abies‐ dominated forest Säby Västerskog, south‐east Sweden as a follow‐up of studies in 1946 and 1998 with the same layout of plots. The vegetation changes were not…

Variations in water economy traits in two <i>Sphagnum</i> species across their distribution boundaries Open
Premise We assessed changes in traits associated with water economy across climatic gradients in the ecologically similar peat mosses Sphagnum cuspidatum and Sphagnum lindbergii . These species have parapatric distributions in Europe and h…

Six Decades of Changes in Pool Characteristics on a Concentric-Patterned Raised Bog Open
Raised bogs are wetland ecosystems which, under the right climatic conditions, feature patterns of pool hollows and hummock ridges. The relative cover and the spatial arrangement of pool and ridge microforms are thought to be influential o…

Spatial heterogeneity ensures long-term stability in vegetation and Fritillaria meleagris flowering in Uppsala Kungsäng, a semi-natural meadow Open
Semi-natural grasslands are becoming increasingly rare, and their vegetation may be affected by environmental changes and altered management. At Kungsängen Nature Reserve, a wet to mesic semi-natural meadow near Uppsala, Sweden, we analyse…

Effects of operational taxonomic unit inference methods on soil microeukaryote community analysis using long‐read metabarcoding Open
Long amplicon metabarcoding has opened the door for phylogenetic analysis of the largely unknown communities of microeukaryotes in soil. Here, we amplified and sequenced the ITS and LSU regions of the rDNA operon (around 1500 bp) from gras…

Climatic drivers of Sphagnum species distributions Open
Peat mosses (genus Sphagnum) dominate most Northern mires and show distinct distributional limits in Europe despite having efficient dispersal and few dispersal barriers. This pattern indicates that Sphagnum species distributions are stron…

Cryptic interactions revisited from ecological networks: Mosses as a key link between trees and hummingbirds Open
Ecological interactions are the glue of biodiversity, structuring communities and determining their functionality. However, our knowledge about ecological interactions is usually biased against cryptic interactions (i.e. overlooked interac…

Environmental drivers of <i>Sphagnum</i> growth in peatlands across the Holarctic region Open
The relative importance of global versus local environmental factors for growth and thus carbon uptake of the bryophyte genus Sphagnum— the main peat‐former and ecosystem engineer in northern peatlands—remains unclear. We measured length g…

Mechanisms behind species-specific water economy responses to water level drawdown in peat mosses Open
Background and Aims The ecosystem engineers Sphagnum (peat mosses) are responsible for sequestering a large proportion of carbon in northern peatlands. Species may respond differently to hydrological changes, and water level changes may le…
Variation in symbiotic N2 fixation rates among Sphagnum mosses Open
Biological nitrogen (N) fixation is an important process supporting primary production in ecosystems, especially in those where N availability is limiting growth, such as peatlands and boreal forests. In many peatlands, peat mosses (genus …

The effects of winter stress on <i>Sphagnum</i> species with contrasting macro- and microdistributions Open
Introduction: Sphagnum L. forms much of the ground cover in northern peatlands. Different species show affinities for bioclimatic regions in Europe (oceanic/continental; northern/southern) and species-specific tolerance of winter condition…

Dispersal limitations and historical factors determine the biogeography of specialized terrestrial protists Open
Recent studies show that soil eukaryotic diversity is immense and dominated by micro‐organisms. However, it is unclear to what extent the processes that shape the distribution of diversity in plants and animals also apply to micro‐organism…

Are we restoring functional fens? – The outcomes of restoration projects in fens re-analysed with plant functional traits Open
In peatland restoration we often lack an information whether re-established ecosystems are functionally similar to non-degraded ones. We re-analysed the long-term outcomes of restoration on vegetation and plant functional traits in 38 Euro…
