Measuring biodiversity from DNA in the air

Current Biology, Journal Year: 2022, Volume and Issue: 32(3), P. 693 - 700.e5

Published: Jan. 6, 2022

The crisis of declining biodiversity1 exceeds our current ability to monitor changes in ecosystems. Rapid terrestrial biomonitoring approaches are essential quantify the causes and consequences global change. Environmental DNA2 has revolutionized aquatic ecology,3 permitting population monitoring4 remote diversity assessments matching or outperforming conventional methods community sampling.3-5 Despite this model, similar have not been widely adopted Here, we demonstrate that DNA from animals can be filtered, amplified, then sequenced air samples collected natural settings representing a powerful tool for ecology. We at zoological park, where spatially confined non-native species allowed us track sources. show used identify their ecological interactions. Air contained 25 mammals birds, including 17 known resident zoo species. also identified food items sampled enclosures detected taxa native local area, Eurasian hedgehog, endangered United Kingdom. Our data airborne eDNA concentrates around recently inhabited areas but disperses away sources, suggesting an ecology potential sampling distance. findings profound as source biomonitoring.

Fishing for fish environmental DNA: Ecological applications, methodological considerations, surveying designs, and ways forward

Molecular Ecology, Journal Year: 2022, Volume and Issue: 31(20), P. 5132 - 5164

Published: Aug. 16, 2022

Abstract Vast global declines of freshwater and marine fish diversity population abundance pose serious threats to both ecosystem sustainability human livelihoods. Environmental DNA (eDNA)‐based biomonitoring provides robust, efficient, cost‐effective assessment species occurrences trends in diverse aquatic environments. Thus, it holds great potential for improving conventional surveillance frameworks facilitate conservation fisheries management. However, the many technical considerations rapid developments underway eDNA arena can overwhelm researchers practitioners new field. Here, we systematically analysed 416 studies summarize research terms investigated targets, aims, study systems, reviewed applications, rationales, methodological considerations, limitations methods with an emphasis on research. We highlighted how technology may advance our knowledge behaviour, distributions, genetics, community structures, ecological interactions. also synthesized current several important concerns, including qualitative quantitative power has recover biodiversity abundance, spatial temporal representations respect its sources. To applications implementing techniques, recent literature was summarized generate guidelines effective sampling lentic, lotic, habitats. Finally, identified gaps limitations, pointed out newly emerging avenues eDNA. As optimization standardization improve, should revolutionize monitoring promote management that transcends geographic boundaries.

Land conversion to agriculture induces taxonomic homogenization of soil microbial communities globally

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: April 29, 2024

Abstract Agriculture contributes to a decline in local species diversity and above- below-ground biotic homogenization. Here, we conduct continental survey using 1185 soil samples compare microbial communities from natural ecosystems (forest, grassland, wetland) with converted agricultural land. We combine our results global meta-analysis of available sequencing data that cover more than 2400 across six continents. Our combined demonstrate land conversion taxonomic functional homogenization bacteria, mainly driven by the increase geographic ranges taxa croplands. find 20% phylotypes are decreased 23% increased conversion, croplands enriched Chloroflexi, Gemmatimonadota, Planctomycetota, Myxcoccota Latescibacterota . Although there is no significant difference composition between land, genes involved nitrogen fixation, phosphorus mineralization transportation depleted cropland. provide insight into consequences land-use change on diversity.
