Using ancient sedimentary DNA to forecast ecosystem trajectories under climate change
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-05-27)Ecosystem response to climate change is complex. In order to forecast ecosystem dynamics, we need high-quality data on changes in past species abundance that can inform process-based models. Sedimentary ancient DNA (sedaDNA) has revolutionised our ability to document past ecosystems' dynamics. It provides time series of increased taxonomic resolution compared to microfossils (pollen, spores), and ... -
Multiplexing PCR allows the identification of within-species genetic diversity in ancient eDNA
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-01-08)Sedimentary ancient DNA (sedaDNA) has rarely been used to obtain population-level data due to either a lack of taxonomic resolution for the molecular method used, limitations in the reference material or inefficient methods. Here, we present the potential of multiplexing different PCR primers to retrieve population-level genetic data from sedaDNA samples. Vaccinium uliginosum (Ericaceae) is a ... -
Steppe-tundra composition and deglacial floristic turnover in interior Alaska revealed by sedimentary ancient DNA (sedaDNA)
(Journal article; Tidsskriftartikkel, 2024-05-16)When tracing vegetation dynamics over long timescales, obtaining enough floristic information to gain a detailed understanding of past communities and their transitions can be challenging. The first high-resolution sedimentary DNA (sedaDNA) metabarcoding record from lake sediments in Alaska—reported here—covers nearly 15,000 years of change. It shows in unprecedented detail the composition of ... -

The process of recording the Sámi place names at Stuorgieddi in the region of southern Troms, Northern Norway
(Chapter; Bokkapittel, 2023)Studies from a Sámi settlement on the island of Iinnasuolu in the region of Southern Troms, Northern Norway, where a large number of traces in the outlying fields from earlier settlements are localised, were the point of departure for several studies on the past and present of the composite history of this settlement. A study of how the local Sámi place names were established locally, and on the ... -
Why avoid naming diseases after animals? The case of “Molluscum contagiosum”
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-03-06)For over 200 years, the name molluscum contagiosum—a dermatological disease—has unfairly associated molluscs (the second largest group of animals on the planet) with this highly contagious infectious disease. Herein, arguments are presented demonstrating the serious problem of continuing to use this name, including animal welfare concerns. Thus, to minimize any unnecessary impacts on the biodiversity ... -
The sedimentary ancient DNA workflow
(Chapter; Bokkapittel, 2023)Sedimentary ancient DNA (sedaDNA) is continuing to revolutionise our understanding of past biological and geological processes by retrieving and analysing the ancient DNA preserved in lake, cave, open terrestrial, midden, permafrozen, and marine environments (Crump, 2021). The study of sedaDNA began in the late 1990s (Coolen and Overmann, 1998) with the first reports of extinct animal sedaDNA in ... -
Phylogenetic position of Canaridiscus and reestablishment of Gonyodiscus (Gastropoda, Discidae)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-13)The genus Canaridiscus M. R. Alonso & Ibáñez, 2011, endemic to the Canary Islands, has a curious taxonomic history and is currently defined based only on the peculiar anatomy of its genital organs. Its relationship to European Discus species and other members of the family Discidae is unclear and its status as a distinct genus remains tentative. In the present study we include a species of Canaridiscus, ... -
How many species of Mollusca are there in Brazil? A collective taxonomic effort to reveal this still unknown diversity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-11)The expression ‘you need to know to conserve’ is a well-known cliche among biologists. Documenting the richness of a group of organisms is the first step towards understanding biodiversity and preparing efficient conservation plans. In this context, many efforts have been made to quantify the number of species on Earth and estimate the number of species still unknown to science. A few countries have ... -
The snails of Super Mario Bros
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-11)Nintendo has recently released a new Mario game, Super Mario Bros. Wonder, a multiplayer platformer involving a good dose of mushrooms, both in-game and presumably during development. But psychedelic trips aside, in the first few stages of the game we are introduced to a completely new (and arguably the best) “enemy” in Mario games: a snail with a fabulous pink shell. Figure 1. Snail (©Nintendo, ... -
