DIY gerontechnology: circumventing mismatched technologies and bureaucratic procedure by creating care technologies of one's own
(Peer reviewed; Journal article, 2019)This study analyses ‘Do‐It‐Yourself’ (DIY) gerontechnologies and shows that they can be viable and valuable alternatives to ‘ready‐made’ gerontechnologies. Using the concept of innosumption, we analyze the work of care ... -
DNA and scale reading to identify repeat spawning in Atlantic salmon: Unique insights into patterns of iteroparity
(Journal article; Peer reviewed, 2023)Iteroparity represents an important but often overlooked component of life history in anadromous Atlantic salmon. Here, we combined individual DNA profiling and scale reading to identify repeat spawners among ~8000 adult ... -
DNA aptamer functionalized hydrogels for interferometric fiber-optic based continuous monitoring of potassium ions
(Peer reviewed; Journal article, 2021)In the present paper, we describe a potassium sensor based on DNA-aptamer functionalized hydrogel, that is capable of continuous label-free potassium ion (K+) monitoring with potential for in situ application. A hydrogel ... -
DNA barcode data reveal biogeographic trends in Arctic non-biting midges
(Journal article; Peer reviewed, 2018)Chironomid flies (non-biting midges) are among the most abundant and diverse animals in Arctic regions, but detailed analyses of species distributions and biogeographical patterns are hampered by challenging taxonomy and ... -
DNA barcode reference libraries for the monitoring of aquatic biota in Europe: Gap-analysis and recommendations for future work
(Journal article; Peer reviewed, 2019)Effective identification of species using short DNA fragments (DNA barcoding and DNA metabarcoding) requires reliable sequence reference libraries of known taxa. Both taxonomically comprehensive coverage and content quality ... -
DNA barcodes and morphology reveal unrecognized species in Chironomidae (Diptera)
(Journal article; Peer reviewed, 2017)For over a decade, DNA barcoding has proven an effective modern tool in taxonomy, evolutionary biology and biodiversity research. Many new species have been discovered and described with DNA barcodes as part of their ... -
DNA barcodes provide insights into the diversity and biogeography of the non-biting midge Polypedilum (Diptera, Chironomidae) in South America
(Peer reviewed; Journal article, 2023)South America, particularly within its tropical belt, is renowned for its unparalleled high levels of species richness, surpassing other major biomes. Certain neotropical areas harbor fragmented knowledge of insect diversity ... -
DNA barcodes successfully delimit morphospecies in a superdiverse insect genus
(Journal article; Peer reviewed, 2018)Polypedilum Kieffer (Diptera: Chironomidae), with 520 currently known species worldwide, can be extremely difficult to identify species level based on the morphology. We used 3,670 cytochrome c oxidase subunit I (COI) ... -
DNA barcoding for species identification of insect skins: A test on Chironomidae (Diptera) pupal exuviae
(Journal article; Peer reviewed, 2017)Chironomidae (Diptera) pupal exuviae samples are commonly used for biological monitoring of aquatic habitats. DNA barcoding has proved useful for species identification of chironomid life stages containing cellular tissue, ... -
DNA barcoding of Aphelopus Dalman (Hymenoptera, Dryinidae) from China, with descriptions of four new species

DNA barcoding of the northern Northeast Atlantic skates (Chondrichthyes, Rajiformes), with remarks on the widely distributed starry ray
(Journal article; Peer reviewed, 2014)The skate fauna in the northern Northeast (NE) Atlantic is poorly investigated, and misidentifications are common. Here, ‘DNA barcoding’ was used to analyse 105 specimens of 15 species previously reported from the area to ... -
DNA base modifications in honey bee and fruit fly genomes suggest an active demethylation machinery with species- and tissue-specific turnover rates
(Journal article; Peer reviewed, 2016)Well-known epigenetic DNA modifications in mammals include the addition of a methyl group and a hydroxyl group to cytosine, resulting in 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) respectively. In contrast, ... -
DNA compaction induced by a cationic polymer or surfactant impact gene expression and DNA degradation
(Journal article; Peer reviewed, 2014)There is an increasing interest in achieving gene regulation in biotechnological and biomedical applications by using synthetic DNA-binding agents. Most studies have so far focused on synthetic sequence-specific DNA-binding ... -
DNA Condensation by Peptide-Conjugated PAMAM Dendrimers. Influence of Peptide Charge
(Peer reviewed; Journal article, 2023)Nucleic acid delivery to cells is an important therapeutic strategy that requires the transport of nucleic acids to intracellular compartments and their protection from enzymatic degradation. This can be achieved through ... -
DNA double-strand breaks in relation to persistent organic pollutants in a fasting seabird
(Journal article; Peer reviewed, 2014)Lipophilic persistent organic pollutants (POPs) are released from fat reserves during fasting, causing increased blood concentrations. Thus, POPs represent a potential anthropogenic stressor during fasting periods. We ... -
