Abstract Global biodiversity in freshwater and the oceans is declining at high rates. Reliable tools for assessing monitoring aquatic biodiversity, especially rare secretive species, are important efficient timely management. Recent advances DNA sequencing have provided a new tool species detection from present environment. In this study, we tested whether an environmental ( eDNA ) metabarcoding approach, using water samples, can be used addressing significant questions ecology conservation....
Marine ecosystems worldwide are under threat with many fish species and populations suffering from human over-exploitation. This is greatly impacting global biodiversity, economy health. Intriguingly, marine largely surveyed using selective invasive methods, which mostly limited to commercial species, restricted particular areas favourable conditions. Furthermore, misidentification of represents a major problem. Here, we investigate the potential metabarcoding environmental DNA (eDNA)...
Remote polar and deepwater fish faunas are under pressure from ongoing climate change increasing fishing effort. However, these communities difficult to monitor for logistic financial reasons. Currently, monitoring of marine fishes largely relies on invasive techniques such as bottom trawling, official reporting global catches, which can be unreliable. Thus, there is need alternative non-invasive qualitative quantitative oceanic surveys. Here we report environmental DNA (eDNA) metabarcoding...
The European weather loach (Misgurnus fossilis) represents one of many freshwater fishes in decline. Efficient monitoring is essential if conservation efforts are to be successful, but due the species' cryptic biology, traditional methods currently use inefficient, time consuming and likely prone non-detection error. Here, we investigate usefulness environmental DNA (eDNA) as an alternative or supplementary method for surveying Danish population, which presumed consist primarily a single...
For several hundred years freshwater crayfish (Crustacea-Decapoda-Astacidea) have played an important ecological, cultural and culinary role in Scandinavia. However, many native populations of noble Astacus astacus faced major declines during the last century, largely resulting from human assisted expansion non-indigenous signal Pacifastacus leniusculus that carry transmit plague pathogen. In Denmark, also narrow-clawed leptodactylus has expanded due to anthropogenic activities. Knowledge...
Abstract Conservation and management of marine biodiversity depends on biomonitoring habitats, but current approaches are resource‐intensive require different for organisms. Environmental DNA (eDNA) extracted from water samples is an efficient versatile approach to detecting aquatic animals. In the ocean, eDNA composition reflects local fauna at fine spatial scales, little known about effectiveness eDNA‐based monitoring communities larger scales. We investigated potential characterize...
Although the Greenland fish fauna has been studied for more than 200 years, new species continue to be discovered. We here take opportunity of International Polar Year 2007–08 (IPY) present an updated check-list fishes and discuss whether growing diversity can explained by global warming. A total 269 from 80 families are known Exclusive Economic Zone (EEZ), based on published literature specimens in museum collections. Since latest publication covering all [Nielsen & Bertelsen 1992], 57...
Abstract Temporal variation in eDNA signals is increasingly explored for understanding community ecology aquatic habitats. Seasonal changes have been addressed using sampling, but very little known regarding short‐term temporal that spans hours to days. To address this, we filtered marine water samples from a single coastal site Denmark every hour 32 h. We used metabarcoding target both fish and broader eukaryote diversity evaluated this community. Results revealed species richness (15–27)...
Marine biodiversity is threatened by human activities. To understand the changes happening in aquatic ecosystems and to inform management, detailed, synoptic monitoring of across large spatial extents needed. Such challenging due time, cost, specialized skills that this typically requires. In an unprecedented study, we combined citizen science with eDNA metabarcoding map coastal fish at a national scale. We engaged 360 scientists collect filtered seawater samples from 100 sites Denmark over...
The latest animal phylum to be discovered, Micrognathozoa, constitutes a rare group of limnic meiofauna. These microscopic 'jaw animals' are among the smallest metazoans yet possess highly complex jaw structures. single species Limnognathia maerski Kristensen and Funch, 2000, was first described from Greenland, later reported remote Subantarctic island more recently discovered in Pyrenees on European continent. Successful collections these three known populations facilitated investigations...
It has been known for about a century that European eels have unique life history includes offshore spawning in the Sargasso Sea 5000–7000 km away from their juvenile and adult habitats Europe northern Africa. Recently hatched eel larvae were historically collected during Danish, German American surveys specific areas southern Sea. During 31 day period of March April 2014, Danish research ships sampled along 15 alternating transects stations across The collection recently (≤12 mm) 70° W...
Abstract The European noble crayfish Astacus astacus is threatened by plague caused the oomycete Aphanomyces astaci , which spread invasive North American (e.g. signal Pacifastacus leniusculus ). Surveillance of status in Norway has traditionally relied on monitoring survival cage‐held crayfish, a method ethical concern. Additionally, trapping used population surveillance. Here, we test whether environmental DNA ( eDNA ) could provide suitable alternative to cage method, and supplement...
Evolution sometimes proceeds by loss, especially when structures and genes become dispensable after an environmental shift relaxes functional constraints. Subterranean vertebrates are outstanding models to analyze this process, gene decay can serve as a readout. We sought understand some general principles on the extent tempo of involved in vision, circadian clock, pigmentation cavefishes. The analysis genomes two Cuban species belonging genus Lucifuga provided evidence for largest loss...
Abstract Environmental DNA (eDNA) provides a promising supplement to traditional sampling methods for population genetic inferences, but current studies have almost entirely focused on short mitochondrial markers. Here, we develop one and nuclear set of target capture probes the whale shark ( Rhincodon typus ) test them seawater samples collected in Qatar investigate potential eDNA‐based studies. The successfully retrieved ~235× (90× − 352× per base position) coverage mitogenome. Using minor...
Abstract Environmental DNA (eDNA) is increasingly used for monitoring marine organisms; however, offshore sampling and time lag from to results remain problematic. In order overcome these challenges a robotic sampler, 2nd generation Sample Processor (ESP), was tested autonomous analysis of eDNA four commercial fish species in 4.5 million liter mesocosm. The ESP enabled situ analysis, consisting water collection, filtration, extraction qPCR which allowed real-time remote reporting archival...
