The continuous decline in Earth's biodiversity represents a major crisis and challenge for the 21st century, there is international political agreement to slow down or halt this decline. large part impeded by lack of knowledge on state distribution – especially since majority species Earth are un-described science. All conservation efforts save essentially depend monitoring populations obtain reliable patterns population size estimates. Such has traditionally relied physical identification...
Abstract Freshwater ecosystems are among the most endangered habitats on Earth, with thousands of animal species known to be threatened or already extinct. Reliable monitoring organisms is crucial for data‐driven conservation actions but remains a challenge owing nonstandardized methods that depend practical and taxonomic expertise, which rapidly declining. Here, we show diversity rare freshwater animals—representing amphibians, fish, mammals, insects crustaceans—can detected quantified...
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)...
Summary Species detection using environmental DNA ( eDNA ) has tremendous potential for contributing to the understanding of ecology and conservation aquatic species. Detecting species methods, rather than directly sampling organisms, can reduce impacts on sensitive increase power field surveys rare elusive The sensitivity however, requires a heightened awareness attention quality assurance control protocols. Additionally, interpretation data demands careful consideration multiple factors....
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 timing of the first human migration into Americas and its relation to appearance Clovis technological complex in North America at about 11,000 10,800 radiocarbon years before present ( 14 C B.P.) remains contentious. We establish that humans were Paisley 5 Mile Point Caves, south-central Oregon, by 12,300 B.P., through recovery mitochondrial DNA (mtDNA) from coprolites, directly dated accelerator mass spectrometry. mtDNA corresponds Native American founding haplogroups A2 B2. dates...
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...
The exploitation of non-invasive samples has been widely used in genetic monitoring terrestrial species. In aquatic ecosystems, such as feces, shed hair or skin, are less accessible. However, the use environmental DNA (eDNA) recently shown to be an effective tool for species presence freshwater ecosystems. Detecting marine environment using eDNA potentially offers a greater challenge due dilution, amount mixing and salinity compared with most To determine potential we specific primers that...
Genetic monitoring can help public agencies implement environmental laws
Terrestrial arthropods comprise the most species-rich communities on Earth, and grassland flowers provide resources for hundreds of thousands arthropod species. Diverse ecosystems worldwide are threatened by various types environmental change, which has led to decline in diversity. At same time, monitoring diversity is time-consuming strictly dependent declining taxonomic expertise. Environmental DNA (eDNA) metabarcoding complex samples demonstrated that information species compositions can...
Recent molecular evidence suggests that crustaceans may have successfully invaded land as insects.
Significance Accurate detection and delineation of schistosomiasis transmission sites will be vital in ongoing efforts to control ultimately eliminate one the most neglected tropical parasitic diseases affecting >250 million people worldwide. Conventional methods detect parasites environment are cumbersome have low sensitivity. We therefore developed an environmental DNA (eDNA)-based method for schistosome aquatic environments. Aquatic eDNA showed higher sensitivity than conventional...
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...
The relationships of crustaceans and hexapods (Pancrustacea) have been much discussed partially elucidated following the emergence phylogenomic data sets. However, major uncertainties still remain regarding position iconic taxa such as Branchiopoda, Copepoda, Remipedia, Cephalocarida, sister group relationship hexapods. We assembled most taxon-rich pancrustacean set to date analyzed it using a variety methodological approaches. prioritized low levels missing found that some clades were...
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...
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)...
