Sphagnum magellanicum has been viewed as being a predominantly circumpolar species in the northern hemisphere, but it occurs southern hemisphere and was originally described from parts of Chile. It is an ecologically important mire ecosystems extensively used model to study processes growth, carbon sequestration peat decomposition. Molecular experimental studies have, however, revealed genetic structure within S. magellanicum, morphological differences associated with these groups. Here we...
In this study of bryophyte diversity in 110 patches spruce forests bilberry, small fern, low herb, tall fern and herb type Ser‐Trøndelag, central Norway, each patch (from 0 24 to 9 33 ha) was classified as one main vegetation successional stage or cutting class The bryophytes were censused randomly established squares 10 × m, supplemented by complete sampling the rest A number environmental variables sampled, data sets treated with DCA CCA Altogether 210 (71 liverworts 139 mosses) found...
Species occurrence data records the location and time of an encounter with a species, is valuable for many aspects ecological evolutionary analyses. A key distinction within species between (1) collected preserved specimens that can be taxonomically validated (i.e., natural history collections), (2) observations, which are more error prone but richer in terms number spread observations. In this study we analyse distribution temporal, spatial, taxonomic environmental coverage specimen-...
Summary Flowering phenology is an indicator of the impact climate change on natural systems. Anthropogenic has progressed over more than two centuries, but ecological studies are mostly short in comparison. Here we harness large‐scale digitization herbaria specimens to investigate temporal trends flowering at a global scale. We trained convolutional neural network model classify images angiosperm herbarium as being flower or not flower. This was used infer across 8 million spanning century...
Abstract Tardigrades are common in many terrestrial environments and habitats. Although little is known on their ecological preferences, previous studies found diversity community composition significantly affected by various variables. This study associated tardigrade species’ records with climatic variables, forest type, substrate categories exploring species communities to find associations characteristics of Norwegian forests. A total 17 473 specimens were identified, encompassing 131...
Abstract The enemy release hypothesis predicts that invasive plant success is in part due to the absence of natural enemies invaded range. However, few studies have assessed how may vary over time or space. Norway has seen a large increase non‐native species past decades. We used historical herbarium records test whether 10 suffered less from (foliar herbivores) at different latitudes and 195 years, compared closely related (congeneric) native species. analysed 2200 specimens 26 Chewing...
The species we have studied the spatiotemporal genetic change in northern dragonhead, a plant that has experienced drastic population decline and habitat loss Europe. We added temporal perspective to monitoring of dragonhead Norway by genotyping herbarium specimens up 200 years old. also assessed whether achieved its potential distribution Norway. To obtain genotype data from 130 collected 1820 2008, mainly (83) but beyond (47), applied microfluidic array consisting 96 SNP markers. assess...
Abstract Climate change has dramatic impacts on ecological systems, affecting a range of factors including phenology, species abundance, diversity, and distribution. The breadth climate systems leads to the occurrence fingerprints change. However, are usually identified across broad geographical scales potentially influenced by publication biases. In this study, we used natural history collections spanning over 250 years, quantify responses change, distributions, taxa, vertebrates,...
The moss and liverwort flora of Zackenberg valley in the Northeast Greenland National Park has been studied based on field investigations literature survey. Altogether 212 taxa are recorded area, with 43 liverworts 169 mosses. Five reported as new to Lophochaete fryei (Perss.) R.M. Schust., Sphagnum orientale L.I. Savicz, Orthothecium lapponicum (Schimp.) C. Hartm., Pohlia vexans (Limpr.) H. Lindb. Tortella alpicola Dixon. Additionally four east Greenland; Grimmia plagiopodia Hedw.,...

Maintenance of genetic diversity is a central aim species conservation, given its positive effect on survival and adaptation in changing environment. Data from different time points key for understanding how populations behave under various conditions. In this regard, herbarium specimens are an invaluable source information the past. Still, utilizing archived biological material studying trends offers challenges such as DNA degradation lack standardized, cost- efficient methods.
