(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-08)<ol> <li>Differences in botanical diet compositions among a large number of moose faecal samples collected during winter correlated with the nutritional differences identified in the same samples (Mantel-r = 0.89, p = 0.001), but the nutritional differences were significantly smaller (p < 0.001).</li> <li>Nutritional geometry revealed that moose mixed Scots pine Pinus sylvestris and Vaccinium spp. ... -
Molecular assessment of dietary variation in neighbouring primate groups
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-02)<ol> <li>Facing rapid environmental changes and anthropogenic habitat destruction, animal behavioural plasticity becomes an adaptive potential that needs to be considered in conservation strategies along with, for example, genetic diversity. Here, we evaluate to what extent non-invasive environmental DNA (eDNA) methods may contribute to the assessment of intraspecies behavioural plasticity in terms ... -
Geometric morphometrics of macro- and meiofaunal priapulid pharyngeal teeth provides a proxy for studying Cambrian “tooth taxa”
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-12)Priapulids are marine, benthic ecdysozoan worms that feed using a distinctive toothed pharynx. While only a handful of lineages have survived to the present day, the Cambrian priapulid stem group left behind a rich record of articulated body fossils and characteristic trace fossils in the form of burrows. Recently, the fossil record of isolated priapulid cuticular elements including pharyngeal teeth ... -
T cell receptor repertoire sequencing reveals chemotherapy-driven clonal expansion in colorectal liver metastases
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)Background - Colorectal liver metastasis (CLM) is a leading cause of colorectal cancer mortality, and the response to immune checkpoint inhibition (ICI) in microsatellite-stable CRC has been disappointing. Administration of cytotoxic chemotherapy may cause increased density of tumor-infiltrating T cells, which has been associated with improved response to ICI. This study aimed to quantify and ... -
The drivers of plant community composition have shifted from external to internal processes over the past 20,000 years
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-19)Internal and external factors regulating the past composition of plant communities are difficult to identify in palaeo-vegetation records. Here, we develop an index of relative entropy of community assembly, which applies to changes in the composition of a community over time, measuring disorder in its assembly relative to disassembly. Historical periods of relatively ordered assembly (negative ... -

Indigenous Religions in the Sixth Missionary District: The Case of the Hillsa Drum
(Chapter; Bokkapittel, 2022)Sámi drums are central in understanding the indigenous religions in earlier Sámi societies.1 The recently reported find of the goavddis (drum) from Hillsá opens for a view into a complex religious world in a period of religious change and transformation. We believe the goavddis is an important object that can help shed light on Sámi cultures in the past and present, as well as contribute to new ... -
Metapopulation regulation acts at multiple spatial scales: Insights from a century of seabird colony census data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-27)Density-dependent feedback is recognized as important regulatory mechanisms of population size. Considering the spatial scales over which such feedback operates has advanced our theoretical understanding of metapopulation dynamics. Yet, metapopulation models are rarely fit to time-series data and tend to omit details of the natural history and behavior of long-lived, highly mobile species such as ... -
Sedimentary ancient DNA reveals local vegetation changes driven by glacial activity and climate.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-07)Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, a lake located directly downstream from the Langfjordjøkel glacier in northern Norway. We used a sedimentary ancient DNA (sedaDNA) metabarcoding dataset of 38 samples from a ... -
New integrated molecular approaches for investigating lake settlements in north-western Europe
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)Lake settlements, particularly crannogs, pose several contradictions—visible yet inaccessible, widespread yet geographically restricted, persistent yet vulnerable. To further our understanding, we developed the integrated use of palaeolimnological (scanning XRF, pollen, spores, diatoms, chironomids, Cladocera, microcharcoal, biogenic silica, SEM-EDS, stable-isotopes) and biomolecular (faecal ... -
Barn Banter: An Exploration of Anthropomorphism and ‘Equine-o-morphism’ as Agency
(Chapter; Bokkapittel, 2022)Barn banter describes and analyzes the sardonic and whimsical verbal exchanges of humor as they function both to develop an elaborated sense of imaginative camaraderie, and to typify constructions of personhood, mutuality and community among horses and those who ride with them in three contemporary South Dakota boarding barns. Although a broad literature on the anthropomorphism of animals, including ...
