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 🐸

@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 🐸

From anarchy to clarity, data pre‐processing and statistical choices influence quantitative environmental DNA (eDNA) analyses Environmental DNA (eDNA) analyses hold great potential for increasing species detection sensitivities and estimating species abundances.

💡 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

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

Scholarly discourse in polarizing interdisciplinary contexts “Let us not speak of them; but look, and pass on.” (Dante, 1867/1320, Inferno, Canto III, line 51). These words could apply to both our original work (Ahme

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.

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! 👽🐸

Same goes for the receiving end of the award. Big thanks! 😀

Spreading #non-native species and human migrations. Superficially similar, but vastly different. We carefully distilled both processes and provide frameworks to support the development of context-specific policies that respect human dignity, and foster cultural diversity.

Parallels and discrepancies between non‐native species introductions and human migration Biological invasions and human migrations have increased globally due to socio-economic drivers and environmental factors that have enhanced cultural, economic, and geographic connectivity. Both proc...

Conceptual and ethical considerations in invasion science Abstract. Invasion science addresses interconnected ecological, economic, and social challenges posed by the introduction of nonnative species. Therefore,

This is a deep self-reflection on invasion science. Wonderfully thought provoking and honest. No short cuts. Every field shld consider doing this. We need more!
