🧬📜 eDNA is moving from research to policy! At the #GuardIAS #SummerSchool, @teuneverts.bsky.social explored how #eDNA can support early detection, rapid response and implementation of EU invasion policies, including Reg. 1143/2014, while highlighting challenges in standardization and acceptance.

🧬📊 How quantitative is quantitative eDNA? At the #GuardIAS #SummerSchool, Teun Everts explored the promise and pitfalls of estimating species densities from eDNA, from ddPCR and qPCR to transport, shedding rates and emerging tools such as eDITH. #eDNA #Biomonitoring

Super stoked to share that our Opinion article is now online at @cp-trendsgenetics.bsky.social!!! With "our" I mean: @teuneverts.bsky.social, @sdellicour.bsky.social and myself!! Here is a link to our piece: authors.elsevier.com/a/1nFgD_3rsx...

After a long time of writing and reviewing, I am proud to share our new perspective paper on #terraforming, the hitherto theoretical, sci-fi-like phenomenon to make extraterrestrial planets hospital to Earth-like life, and its similarities and differences with #bioinvasions, now published in #Oikos!

How do you find a cryptic invader hiding in thick mud? #GuardIAS is using advanced eDNA barcoding and trialing "quicklime" treatments to protect Belgian wetlands from the African clawed frog. Read the case study and factsheet: 🔗 guardias.eu/case-study-3... #IAS #InvasiveSpecies #BioInvasions

New online! Sleeper populations as insidious forms of invasion debt

I was invited by @natrevbiodiv.nature.com to write a short piece on one of my all time favorite papers. It cover the concept of sleeper populations; populations of non-native species that persist at low densities, but can get triggered by environmental change and become highly invasive!👽

First global synthesis of Centrarchidae invasions across taxonomy, pathways, impacts and risk. Centrarchids are globally valuable and invasive at the same time. This is the first review to quantify that duality at family level and to link distribution, pathways, traits and risk in one framework

Happy to see my work as one of the most cited #papers in Ecological Applications. We show that #eDNA can reveal species-specific impacts of non-native #bullfrogs on native #amphibians, alligning with global patterns emerging from a #meta-analysis! doi.org/10.1002/eap....

How biological invasions are silently remodelling ecosystems: our paper in @plosbiology.org about the extension of the #EICAT impact classification of biological invasions has now an outreach piece! Read the (shorter and easier) version of the story here: theconversation.com/how-biologic...

A single marbled crayfish can start a population alone. 🦞 In the Netherlands, we're using eDNA to protect ponds from this rapid invader. At this stage, control is still possible! Read more: guardias.eu/tracking-mar... #GuardIAS #InvasiveSpecies #Netherlands #eDNA #Science

🚨 New #OA review in Biological Reviews: The impacts of biological invasions 🚨 With researchers across the globe, we synthesize nearly a century of evidence across taxa and ecosystems to clarify what #invasion #impacts are, how they arise, and why they are hard to assess. doi.org/10.1002/brv....

Hey, I succesfully defended my #PhD! 🐸👽 I have been using #eDNA and #popgen to study the distribution, spread, and impact of American #bullfrogs in Flanders. Grateful to my promotors and everyone that has supported me. Now, the next chaper awaits as @inbo.be postdoc: @guardias.bsky.social

Fresh insights at #GuardIAS Conference from @teuneverts.bsky.social : pooled #eDNA sampling is proving a smart, cost-efficient way to track the northernmost Xenopus laevis invasion. With 100+ km² already occupied, this approach delivers fast, actionable intelligence for cross-border management.

Back from my 2nd time attending the #InvaPact workshops, aiming to assess ecological #impacts of biological #invasions globally. Its incredible how well these workshops are organized, and the intended impacts they will have on scientific literature. #grateful #newfriends #inspired #motivated

Pooled eDNA sampling effectively maps the northernmost African clawed frog invasion, enabling fast, cost-efficient cross-border detection and management. Coordinated action is required along the French-Belgian border. 🔗 doi.org/10.3897/neob... @teuneverts.bsky.social @inbo.be

great work from @teuneverts.bsky.social @inbo.be belgian #xenopus invasion is published still great needs for cross border collaboration @neobiota.pensoft.net @neobiota.bsky.social neobiota.pensoft.net/article/1503...

Day 2 of the #GuardIAS meeting was all about our 11 case studies! Great to see the nitty-gritty of using eDNA & drones for detection, modelling population spread, and launching new citizen science projects. Also got a preview of upcoming online events from at @invasivesnet.bsky.social.

Teun Everts @inbo.be showcasing the #xenopuslaevis @guardias.bsky.social case study rapid response effectiveness can be measured w #eDNA amazing conservation work

Wrap on Day 1 of the GuardIAS project meeting in Thessaloniki! 🇬🇷 A jam-packed day of collaboration, covering everything from AI & eDNA for tracking invasive species to boosting citizen science. Ready for Day 2! #GuardIAS #InvasiveSpecies

Five years of hard work comes down to today... Time for my internal #PhD defence! Lets hope I make it out alive 🐸 #eDNA #genetics #SNPs #Bioinvasions

@teuneverts.bsky.social en Rein Brys testen uit of snoek kan worden ingezet als inheemse roofvis om de grote stierkikkerpopulaties - zoals in en rond Geel - in te dijken. Teun, Rein en de collega's voeren een proef uit aan de hand van vier 'vijvertypes'. youtu.be/zQYOWiKHCmY

Plenary Speaker Announcement | We are pleased to announce that David Dudgeon will be presenting ‘Global homogenization of freshwater fish diversity during the Anthropocene: evidence from tropical East Asia’ at ICAIS 2026.

#Chytrid fungus and #ranavirus jeopardize amphibian well-being. We present a novel duplex #eDNA assay to detect both simultaneously from water samples. We also show that the presence and density of #invasive #bullfrogs is related to that of chytrid fungus, but not ranavirus, in space and time 🐸

SAVE THE DATE #Neobiota2026 is coming to Brussels Leave your contact details www.neobiota2026.org

💡 Think carefuly about the analytical choices made when relating #eDNA #concentrations to species #abundance and #density! ⚠️ We show that a variety of (suboptimal) methods are used to investigate these relationships, and that these problematic statitiscs lead to flawed outcomes 👇 #OA article below

Abstract submissions have just opened for #ICAIS2026, hosted in Northern Ireland at @qubelfastofficial.bsky.social The conference theme is "Transcending Boundaries", considering habitats, disciplines, regions, and research-policy interfaces Deadline: September 26, 2025 icais.org/icais-2026/c...

Painful to see how our comprehensive, interdisciplinary review on the dangers of comparing biological #invasions to human migration was misinterpreted and decontextualized. We share the same vision, and urge for discussion rather than villainization. Below our response. doi.org/10.1093/bios...

📣📣 We would like to introduce the bi-annual #InvasionsNewsletter, an open-access digital magazine and a collaborative effort of individuals, networks, and organizations from around the world! You can access it here: joom.ag/mIjd

After 3 years of sampling, lab work, bio informatics, statistical analyses and writing, I am very pleased to see the fifth data chapter of my #PhD published in #Heredity! We combine occurrence records and population #genetics to reveal the €spread dynamics of invasive #bullfrogs! 👽🐸
