“…What has become apparent from studies in lentic systems (ponds and lakes) is that semi‐aquatic and terrestrial mammals can also be detected (Hänfling et al, ; Harper et al, ). As a result, there has been an increasing focus on the use of both vertebrate (Harper et al, ) and mammal‐specific primer sets (Leempoel, Herbert, & Hadly, ; Sales, Kaizer, et al, ; Ushio et al, ) for detecting mammalian communities using eDNA metabarcoding.…”

Environmental DNA (eDNA) metabarcoding has revolutionized biomonitoring in both marine and freshwater ecosystems. However, for semi‐aquatic and terrestrial animals, the application of this technique remains relatively untested. We first assess the efficiency of eDNA metabarcoding in detecting semi‐aquatic and terrestrial mammals in natural lotic ecosystems in the UK by comparing sequence data recovered from water and sediment samples to the mammalian communities expected from historical data. Secondly, using occupancy modelling we compared the detection efficiency of eDNA metabarcoding to multiple conventional non‐invasive survey methods (latrine surveys and camera trapping). eDNA metabarcoding detected a large proportion of the expected mammalian community within each area. Common species in the areas were detected at the majority of sites. Several key species of conservation concern in the UK were detected by eDNA sampling in areas where authenticated records do not currently exist, but potential false positives were also identified. Water‐based eDNA metabarcoding provided comparable results to conventional survey methods in per unit of survey effort for three species (water vole, field vole and red deer) using occupancy models. The comparison between survey ‘effort’ to reach a detection probability of ≥.95 revealed that 3–6 water replicates would be equivalent to 3–5 latrine surveys and 5–30 weeks of single camera deployment, depending on the species. Synthesis and applications. eDNA metabarcoding can be used to generate an initial ‘distribution map’ of mammalian diversity at the landscape level. If conducted during times of peak abundance, carefully chosen sampling points along multiple river courses provide a reliable snapshot of the species that are present in a catchment area. In order to fully capture solitary, rare and invasive species, we would currently recommend the use of eDNA metabarcoding alongside other non‐invasive surveying methods (i.e. camera traps) to maximize monitoring efforts.

Assessing and studying the distribution, ecology, diversity and movements of species is key in understanding environmental and anthropogenic effects on natural ecosystems. Although environmental DNA is rapidly becoming the tool of choice to assess biodiversity there are few eDNA sample types that effectively capture terrestrial vertebrate diversity and those that do can be laborious to collect, require special permits and contain PCR inhibitory substances, which can lead to detection failure. Thus there is an urgent need for novel environmental DNA approaches for efficient and cost-effective large-scale routine monitoring of terrestrial vertebrate diversity. Here we show that DNA metabarcoding of airborne environmental DNA filtered from air can be used to detect a wide range of local vertebrate taxa. We filtered air at three localities in Copenhagen Zoo, detecting mammal, bird, amphibian and reptile species present in the zoo or its immediate surroundings. Our study demonstrates that airDNA has the capacity to complement and extend existing terrestrial vertebrate monitoring methods and could form the cornerstone of programs to assess and monitor terrestrial communities, for example in future global next generation biomonitoring frameworks.

“…DNA metabarcoding from environmental samples has the potential to be used as an early warning system for the detection of invasive non‐native species, can be used for continuous monitoring programmes, and has been extensively applied for tracking biological invasions in aquatic ecosystems (Deiner et al ). eDNA metabarcoding studies targeting mammalian communities were relatively rare in comparison with other taxonomic groups (Sales et al ), but this may change now that there are established metabarcoding protocols for detecting and monitoring whole communities using vertebrate (Harper et al ) or mammal‐specific primer sets (Ushio et al , Sales et al , b).…”

“…It is therefore essential that specialised eDNA laboratory facilities (akin to working with ancient DNA) are used (Zinger et al ). Another consideration is the existence of gaps in customised or online reference databases for identifying sequences to the appropriate species level in under‐studied geographic regions (Sales et al ). However, with a carefully planned experimental design and the appropriate field and laboratory controls (Zinger et al ), eDNA metabarcoding has the potential to be applied for early detection and ongoing surveillance of invasive mammals (Harper et al , Sales et al ).…”

Genetic tools in the management of invasive mammals: recent trends and future perspectives

Invasive non‐native species are now considered to be one of the greatest threats to biodiversity worldwide. Therefore, efficient and cost‐effective management of species invasions requires robust knowledge of their demography, ecology and impacts, and genetic‐based techniques are becoming more widely adopted in acquiring such knowledge. We focus on the use of genetic tools in the applied management of mammalian invasions globally, as well as on their inherent advantages and disadvantages. We cover tools that are used in: 1) detecting and monitoring mammalian invaders; 2) identifying origins and invasive pathways; 3) assessing and quantifying the negative impacts of invaders; and 4) population management and potential eradication of invasive mammals. We highlight changes in sequencing technologies, including how the use of techniques such as Sanger sequencing and microsatellite genotyping, for monitoring and tracing invasive pathways respectively, are now giving way to the use of high‐throughput sequencing methods. These include the emergence of environmental DNA (eDNA) metabarcoding for the early detection of invasive mammals, and single nucleotide polymorphisms or whole genomes to trace the sources of invasive populations. We are now moving towards trials of genome‐editing techniques and gene drives to control or eradicate invasive rodents. Genetic tools can provide vital information that may not be accessible with non‐genetic methods, for the implementation of conservation policies (e.g. early detection using systematic eDNA surveillance, the identification of novel pathogens). However, the lack of clear communication of novel genetic methods and results (including transparency and reproducibility) to relevant stakeholders can be prohibitive in translating these findings to appropriate management actions. Geneticists should engage early with stakeholders to co‐design experiments in relation to management goals for invasive mammals.
