General practitioners’ experiences with children and adolescents with functional gastro-intestinal disorders: a qualitative study in Norway

Anne Brodwall & Mette Brekke
Objective: Functional gastrointestinal disorders (FGIDs) are common in children and adolescents. During 2016 and 2019, we investigated the experiences among parents of children with FGIDs and interviewed their children and adolescents during 2020. The aim of the present study was to explore the experiences among general practitioners (GPs) who treat this patient group. Design: Individual interviews with open-ended questions were audio recorded and transcribed, and subsequently analysed using descriptive content analysis. Setting: Urban and rural...

Seasonal release from competition explains partial migration in European moose

Bram Van Moorter, Navinder Singh, Christer Rolandsen, Erling Solberg, Holger Dettki, Jyrki Pusenius, Johan Månsson, Hakan Sand, Jos Milner, Ole Roer, Aimee Tallian, Wiebke Neumann, Göran Ericsson & Atle Mysterud
Partial migration, whereby a proportion of a population migrates between distinct seasonal ranges, is common throughout the animal kingdom. However, studies linking existing theoretical models of migration probability, with empirical data are lacking. The competitive release hypothesis for partial migration predicts that due to density-dependent habitat selection, the proportion of migrants increases as the relative quality and size of the seasonal range increases, but decreases with increasing migration cost and population density. To test this...

Molecular dietary analyses of western capercaillies (Tetrao urogallus) reveal a diverse diet

Physilia Chua, Youri Lammers, Emmanuel Menoni, Torbjørn Ekrem, Kristine Bohmann, Sanne Boessenkool & Inger Alsos
Conservation strategies centred around species habitat protection rely on species’ dietary information. One species at the focal point of conservation efforts is the herbivorous grouse, the western capercaillie (Tetrao urogallus), which is an indicator species for forest biodiversity conservation. Non-molecular means used to study their diet are time-consuming and at low taxonomic resolution. This delays the implementation of conservation strategies including resource protection due to uncertainty about its diet. Thus, limited knowledge on diet is...

Expanding forests in alpine regions lead to a corresponding shift in belowground fungal communities

Synnøve Smebye Botnen, Lea-Rebekka Tonjer, Ella Thoen, Sunil Mundra, Luis Morgado, Line Nybakken, Anders Bryn & Håvard Kauserud
Climate change causes upward shift of forest lines worldwide, with consequences on soil biota and carbon sequestration (C). We here analyse compositional changes in the soil biota across the forest line ecotone, an important transition zone between different ecosystems. We collected soil samples along transects stretching from subalpine mountain birch forests to low-alpine vegetation. Soil fungi and micro-eukaryotes were surveyed using DNA metabarcoding of the 18S and ITS2 markers, while ergosterol was used to quantify...

Cheilostome cyclostome assemblage 2020

Lee Hsiang Liow
Examining the supposition that local-scale competition drives macroevolutionary patterns has become a familiar goal in fossil biodiversity studies. But it is an elusive goal, hampered by inadequate confirmation of ecological equivalence and interactive processes between clades, patchy sampling, few comparative analyses of local species assemblages over long geologic intervals, and a dearth of appropriate statistical tools. We address these concerns by reevaluating one of the classic examples of clade displacement in the fossil record, in...

Metagenomics: A viable tool for reconstructing herbivore diet

Physilia Chua, Alex Crampton-Platt, Youri Lammers, Inger Alsos, Sanne Boessenkool & Kristine Bohmann
Metagenomics can generate data on the diet of herbivores, without the need for primer selection and PCR enrichment steps as is necessary in metabarcoding. Metagenomic approaches to diet analysis have remained relatively unexplored, requiring validation of bioinformatic steps. Currently, no metagenomic herbivore diet studies have utilised both chloroplast and nuclear markers as reference sequences for plant identification, which would increase the number of reads that could be taxonomically informative. Here, we explore how in silico...

Sperm length divergence as a potential pre-zygotic barrier in a passerine hybrid zone

Emily Cramer, Gaute Grønstøl, Logan Maxwell, Adrienne Kovach & Jan Lifjeld
The saltmarsh sparrow Ammospiza caudacuta and the Nelson’s sparrow A. nelsoni differ in ecological niche, mating behavior, and plumage, but they hybridize where their breeding distributions overlap. In this advanced hybrid zone, past inter-breeding and current back-crossing result in substantial genomic introgression in both directions, although few hybrids are currently produced in most locations. However, because both species are non-territorial and have only brief male-female interactions, it is difficult to determine to what extent assortative...

Age matters: Demographic senescence in the moss Polytrichastrum formosum

Ditte Tholstrup, Rune Halvorsen & Johan Dahlgren
It is known that many animal species senesce demographically, showing a decrease in survival and/or fertility with age. Though there is mounting evidence for and against senescence in various flowering plant species, the question of whether senescence also occurs in other plant taxa, such as mosses and other bryophytes, remains unanswered. We used GAMMs (generalized additive mixed models) and GLMMs (generalized linear mixed models) to assess effects of age on survival, size and the monocarpic...

Data from: Traits mediate niches and co-occurrences of forest beetles in ways that differ among bioclimatic regions

Ryan C. Burner, Jörg G. Stephan, Lukas Drag, Tone Birkemoe, Jörg Muller, Tord Snäll, Otso Ovaskainen, Mária Potterf, Juha Siitonen, Olav Skarpaas, Inken Doerfler, Martin M. Gossner, Peter Schall, Wolfgang W. Weisser & Anne Sverdrup-Thygeson
Aim To investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e., their niches), (2) whether these same traits could predict co-occurrence patterns, and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Methods We complied capture records...

Arthropod OTUs in fruit bodies of wood decay fungi

Lisa Lunde & Sundy Maurice
Biological communities within living organisms are structured by their host’s traits. How host traits affect biodiversity and community composition is poorly explored for some associations, such as arthropods within fungal fruit bodies. Using DNA metabarcoding, we revealed the arthropod communities in living fruit bodies of eleven wood-decay fungi from boreal forests and investigated how they were affected by different fungal traits. Arthropod diversity was higher in fruit bodies with a larger surface area-to-volume ratio, suggesting...

Circulating microRNA profile unveils mechanisms of action of acitretin for psoriasis vulgaris

Lin Chen, Jie Li, Ying Yao, Shanlong Wang, Shuangjin Zheng, Xinggang Ju & Bin Zhang
Psoriasis vulgaris is a common chronic and recurrent inflammatory skin disease. In clinical practice, acitretin is the first-line treatment drug for psoriasis vulgaris. MicroRNAs (miRNAs) play a vital role in the initiation and development of psoriasis vulgaris. However few studies focused on the mechanisms of acitretin in the treatment of psoriasis vulgaris from the perspective of miRNAs. Here, the expression profiles of circulating miRNAs in the plasma of 12 patients with psoriasis vulgaris before and...
