📢Call for papers! We're editing a Special Issue in Environmental DNA and would love to receive your submission on #eDNA or #eRNA for #freshwater ecology, monitoring and/or biosecurity. 🐟🏞️💧🧬 Original research, methods, reviews & case studies welcome! Deadline: 20 Feb 2027.

Environmental DNA

Environmental DNA is an open access eDNA journal that provides an international forum for basic & applied research on all areas of eDNA analysis.

Very excited to have been (a small) part of this impressive work based on collaborations across the globe!

Unified analysis of #global 🌐 🌍 #riverine #eDNA 🧬 reveals common associations of #fish #biodiversity 🐟 🐠 with drainage characteristics. Out now @natecoevo.nature.com : www.nature.com/articles/s41... 🧵1/6

Impressive work led by #YanZhang & @florianaltermatt.bsky.social in Molecular Ecology: a global reanalysis of riverine fish #eDNA datasets – including our own data 🎉. Despite methodological differences, the core biodiversity estimates are robust! 👉 onlinelibrary.wiley.com/journal/1365...

New paper: eDNA metabarcoding at African savanna waterholes revealed 95 species. Wet season shows overall richness, dry season favors mammals. Primer choice matters. We’re excited about eDNA powering wildlife monitoring! 🦒🐢🪿🐍 doi.org/10.1111/eva.... #eDNA #Africa #wildlife

Very excited to have our pollen trap set up to collect airborne #eDNA during our second sampling week (=summer sampling). We will compare the results of the 7-day #airDNA sampling to soil sampling to assess ambient vertebrate biodiversity. If, both the trap and the eDNA survive this heatwave! 🥵 🫨 🧬

🎉 A very excited Prof. Dr. Nikol Kmentová of @uhasselt.bsky.social celebrates our first #eDNA #metabarcoding library from Burundi’s freshwater! 🌍 Her #AfroWetMap project monitors African wetlands from flatworms 🪱 to snails 🐚 (and yes, we're checking on vertebrates too! 🦛🐊).

🐕🧬💧 New article is out! We tracked how terrestrial mammals like dogs shed DNA into water bodies . Results show that activities like "crossing through" and "defecating" had the highest shedding rates and how direct versus indirect interaction affect eDNA detection probabilities. #eDNA #biomonitoring

Water Interaction Type Affects Environmental DNA Shedding Rates of Terrestrial Mammal eDNA Into Surface Water Bodies

Although shedding rates for aquatic species are well studied, little is known about terrestrial mammal shedding rates in water. In this study, we quantify eDNA shedding rates from domestic dogs durin...

Buffy Smith @theednaconsultancy.bsky.social compared #iDNA and airborne #eDNA for #biodiversity in fragmented forest landscape. #iDNA more spatially sensitive. More domestic species detected with #iDNA than #eDNA tended to capture larger native mammals - differential shedding rates? #UKDNAWG25

@clarecowgill.bsky.social compared #eDNA, #ecoacoustics + camera trapping for monitoring #terrestrial rewilding. Aquatic, soil + surface (tree rolling) #eDNA used. Most species with #ecoacoustics + tree rolling. More mammals + amphibians with #eDNA. More birds with #ecoacoustics #UKDNAWG25

Last session of #UKDNAWG25 is standards, best practice, current knowledge gaps and future opportunities. @leeselab.bsky.social discusses how we go from wild west of #eDNA to standards. Challenges are limited comparability of methods and unequal access to technical infrastructure and funding.

Tamara Schenekar used #eDNA from waterholes to assess #terrestrial vertebrates in Savannah ecosystems. Seasonal water + sediment sampling compared to camera traps. More species detected with #eDNA. Species identity, body length, time since visit + duration all influenced detection #UKDNAWG25 3/6
