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 and conservation of molluscs, we follow WHO best practices in naming diseases to suggest the use of the new term ‘wpox’ or ‘water warts’ as a synonym for molluscum contagiosum.<br />

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 2003 (Hofreiter et al., 2003; Willerslev et al., 2003). Since then, it has been shown that sedaDNA can be recovered at high resolution from recent (10<sup>1</sup>-10<sup>2</sup> year-old) (e.g., Capo et al., 2017) through to deep-time (10<sup>5</sup>-10<sup>6</sup> year-old) sediments from a vast diversity of environments (Crump et al., 2021; Zavala et al., 2021; Armbrecht et al., 2022; Kjær et al., 2022). Unlike traditional palaeoenvironmental and palaeoecological proxies, sedaDNA is unique in that it is derived from any type of organism that was present in the local area and that may contain population-level information. This latter characteristic means that, unlike any other comparable proxy, sedaDNA can be used for evolutionary analyses (Gelabert et al., 2021; Lammers et al., 2021; Pedersen et al., 2021; Vernot et al., 2021). <p>
<p>The advent of next-generation sequencing (NGS) provided massively enlarged, yet economically feasible, dataset sizes and increased analytical sensitivity that has allowed the field to flourish by generating robust datasets in which contamination can be detected and controlled, and hypotheses can be tested. Coupled with ongoing methodological innovations in both molecular data generation and bioinformatics analysis techniques, NGS has driven the exponential growth in sedaDNA research over the past two decades. <p>
<p>In this chapter, we present an overview of the state-of-the-art for the sedaDNA workflow.

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, C. textilis (Shuttleworth, 1852), in a molecular phylogenetic framework of the Discoidea to investigate its position in the superfamily’s tree. Canaridiscus is retained as a distinct genus in Discidae, but Discus is shown to be polyphyletic. Thus, the genus Gonyodiscus Fitzinger, 1833 is here resurrected to include 2 European species, reclassified as G. perspectivus (Megerle von Mühlfeld, 1816) and G. rotundatus (O. F. Müller, 1774). Discus Fitzinger, 1833 is restricted to a clade containing mostly North American species.<br />

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 complete and integrated databases estimating the approximate number of species recorded for their territory, particularly in the Global South. In Brazil, a country of continental dimensions, revealing the richness of the second most diverse clade of invertebrates (=Mollusca) has been a goal of taxonomists. Recently, in an unprecedented, collective, and integrated effort among Brazilian malacologists, it was possible to estimate how many valid species of molluscs are there in Brazil. In this effort, more than 30 mollusc experts joined together to update the Taxonomic Catalogue of the Brazilian Fauna (TCBF), a governmental website that allows a quick and real-time updating of all Metazoan. So far, more than 5,000 updates have been made in TCBF, indicating the presence of 3,552 valid species of molluscs in Brazil, distributed among the main clades as follows: Caudofoveata (10 spp.), Solenogastres (6 spp.), Polyplacophora (35 spp.), Scaphopoda (43 spp.), Cephalopoda (92 spp.), Bivalvia (629 spp.) and Gastropoda (2,737 spp.). The present study, in addition to demonstrating for the first time the richness of Brazilian molluscs, also presents the state of the art of this important phylum of invertebrates highlighting its most representative and neglected groups.<br />

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, 2023; fair use). Source: Super Mario Wiki (https://mariowiki.com/). So far, this critter remains unnamed, but the Super Mario Wiki refers to it as Snail, with a capital S. So, I will use this name throughout this article. It’s not very creative, I agree, but maybe safer than risking a bad pun like in some Pokémon names. The Snail has a pink shell and a green soft body. Its tentacles are striped and its eyes are located below the tentacles. Overall, it is a cartoonish design – as it should be – but an interesting one nevertheless. First, it’s kinda cute. Secondly, it has some curious features that are an excuse for me to discuss a little bit about real-world biology. So, let’s get down to the snail science.<br />

We analysed the pollen and spores extracted from 73 samples of lacustrine sediments from
Colesdalen in Svalbard (Lake Tenndammen) as well as 10 soil samples collected from the lake’s shores.
In total, 56 pollen taxa were recorded from the sediments spanning the last 800 years, whilst 35 pollen
types were found in the soil samples. Pollen was categorised as (i) regional (from Svalbard); (ii) exotic
to Svalbard today; or (iii) of mixed or unclear origin. Major changes in pollen assemblages after ca
1900 CE were associated with human impact. Around 1920 CE, the first signs of introduced plant taxa
were identified, by the presence of Apiaceae and Fabaceae pollen. Additionally, large-sized pollen with
a thick exine and annulus diameter of 10.6–13 lm, identified as Poaceae/Cerealia type, was constantly
present after ca 1920 CE. Other exotic pollen, including Ulmus, Juglans, and tropical pollen of Albizia/
Mimosa type, Eucalyptus type, Acalypha type, and Passiflora type, are found only during the 1930s to
1960s, which is the period associated with the most intensive mining activity and human migration to
and from Colesdalen. Furthermore, the repeated occurrence of Myrica (gale) type and Erica type occurring both in the lake sediment and in the soil samples is best explained by the migration of geese
from Scotland (UK). Our research demonstrates how precisely human history can be reflected in the
lake sediments of the Arctic environment.<br />

Most musical instrument augmentations aim to only fit one specific instrument and depend on an external sound system to work as intended. In a more acoustic concert setting this often alienates the electronic sound component. The FLAPIBox is an integrated solution that fits most acoustic instruments and use its own resonance for playing electronic sound in a more organic way—through the instrument itself. Reviewing related works and exploring different hardware and software components, a modular prototype has been built. The results of this preliminary study make the body of planning and building the first integrated breadboard prototype. Because of its flexible design, the FLAPIBox can use several different microphone, and loudspeaker technologies. Using inexpensive components and developing open-source software, the FLAPIBox is both affordable and accessible. The development of the FLAPIBox aim to result in a stable and predictable platform, yet open and versatile enough for further development.<br />

Background - The small genus Coelophthinia Edwards, 1941 of the subfamily Gnoristinae (Diptera, Mycetophilidae) is so far known to harbour four species from the Palaearctic, Nearctic and Neotropical Regions. Extensive DNA barcoding of fungus gnats of the family Mycetophilidae through the International Barcode of Life project (iBOL) have initiated integrative studies resulting in taxonomic upgrades and a better understanding of many species and their delimitation. The opportunity was also taken to describe the mitogenome of a member of Coelophthinia for the first time. <p>
<p>New information - The integrative studies give evidence for splitting the European species C. thoracica Edwards, 1941 into three different species. Four new species are described from the USA, Japan and the Nordic Region in Europe, Coelophthinia cirra Kerr sp. n., Coelophthinia itoae Kurina sp. n., Coelophthinia lata Kjaerandsen sp. n. and Coelophthinia loraasi Kjaerandsen sp. n., raising the number of Holarctic species from two to six. The mitogenome of Coelophthinia loraasi sp. n. is described and analysed.<br />

In the early 1980s, a runestone fragment with a Christian inscription from the early eleventh century was discovered in Harstad town, northern Norway, in excavated masses originating from the farm Ervika. Runestones are very rare archaeological finds in this region, but, despite being included in runological overviews, the Ervika stone has not been studied or published by archaeologists or historians. This reflects a tendency where evidence of early medieval Christian influences and the Christianization processes in northern Norway have been surprisingly little discussed apart from general overviews and some local studies of specific find categories. In this article, we aim to initiate a broader debate about the complexities of the Christianization processes in northern Norway by presenting and evaluating relevant finds. This includes the material that has emerged over the last decade due to increased interest in private metal detecting. We emphasize the particularities of the geopolitical and sociocultural context in the north, where impulses from the Eastern Church and Saami culture and religion may have affected the reception and practice of the new religion. The Ervika runestone fragment serves as a point of departure, and we describe the find and its context in some detail to ensure it is included in future research by runologists, archaeologists, and historians.<br />

This reflects a tendency where evidence of early medieval Christian influences and the Christianization processes in northern Norway have been surprisingly little discussed apart from general overviews and some local studies of specific find categories. In this article, we aim to initiate a broader debate about the complexities of the Christianization processes in northern Norway by presenting and evaluating relevant finds. This includes the material that has emerged over the last decade due to increased interest in private metal detecting. We emphasize the particularities of the geopolitical and sociocultural context in the north, where impulses from the Eastern Church and Saami culture and religion may have affected the reception and practice of the new religion. The Ervika runestone fragment serves as a point of departure, and we describe the find and its context in some detail to ensure it is included in future research by runologists, archaeologists, and historians.
