8/8 Work led by #YanZhang @UZH @eawag.bsky.social , with many co-authors and data contributors across 40+ institutions. @mattleray.bsky.social @merinrejichacko.bsky.social @leeselab.bsky.social @wslresearch.bsky.social @loicpellissier.bsky.social & many more 🇨🇭 🇩🇪 🇫🇷 🇨🇳 🇧🇷 🇺🇲 🇬🇧 🇦🇺 🇹🇭 🇪🇸 🇯🇵 🇳🇴 🇦🇹
7/8 🔀 Overall, the suitability and potential of eDNA for global biodiversity monitoring is corroborating overall robust biodiversity estimates, irrespective of the bioinformatic approaches.
6/8 🔹#Year of sampling had a positive effect on taxonomic congruence. This is promising❗ It indicates that technological advances and data-base completeness have improved our assessment ability!
5/8 🔹Contrastingly, congruence of species identity varied more extensively across datasets, mostly reflecting different completeness and regional relevance of reference databases. Restricting taxonomic assignment to basin-specific species pools improved species identification accuracy.
4/8 🔹 We found that #species #richness estimates and metrics of community structure derived under a common bioinformatic workflow were overall #consistent with those of original analyses, despite the relatively high variability in bioinformatic analyses in the respective original studies. 📊 📈
3/8🔹 The meta-analysis of 58 riverine fish eDNA metabarcoding studies 🐡 🐟 🐠 🧬 covered 1818 sampling sites worldwide and evaluated the robustness of eDNA-derived biodiversity patterns.
2/8 We conducted an integrated reanalysis of #global riverine #fish eDNA datasets, showing both #robustness and #congruence of biodiversity conclusions, just published in #MolecularEcology.

Effective #biodiversity 🐟 🐠 🤝 policy making depends on #comparable and #generalisable data. We demonstrate how #eDNA 🧬 is empowering 💪 🌍 🌐 global biodiversity analyses.

When I analyzed these phenological changes 15 years ago they were already very visible, but I am still amazed on how this trend has intensified and generations added! pmc.ncbi.nlm.nih.gov/articles/PMC...
can see this with so nany species now happening

Also many thanks to the reviewers and evaluation panel for their work and support! www.snf.ch/en/WAvYcY7aw...
Just received positive decision that the project will be fully funded (with cuts at many funding agencies, this isn't exactly a given right now...), meaning that @francoiskeck.bsky.social , myself & others in the group will strive for deriving predictive models of the human impact on biodiversity.
#Research and #innovation depends on good ideas, but also on #funding to turn these into reality.
I am thus very grateful to Schweizerischer Nationalfonds SNF for supporting our project "#BioTesselate: Projecting the #Human #Impact on #Biodiversity". 🌎 🐜 🦠 🦐 🦀 🏭 🎣 🧪

3/3 Building e.g. on how shifting leaf fall phenology disrupts ecosystem function www.cell.com/current-biol... or how changing seasonality and phenology mediate the effects of migration across meta-ecosystems (www.biorxiv.org/content/10.6...) we want to generalise temporal meta-ecosystem effects.
2/3 In this #session we will focus on synthesizing temporal components in ecology and integrating #temporal dynamics and #phenology into meta-ecosystem theory and empirical work. We aim to bring together #theoreticians and #empiricists to contribute to the session.
Give #time ⏳ to #Meta-#Ecosystem 🍂 🍃 🌊 #Ecology!
Interested in integration of a temporal dimension in meta-ecosystem research? Join our session (#13) at #NSO-#GFÖ conference in Odense, Denmark, Sep. 13–17 2026.

Jesse Jackson, whose impassioned oratory and vision of a “rainbow coalition” of the poor and forgotten made him the nation's most influential Black figure in the years between the civil rights crusades of Martin Luther King Jr. and the election of Barack Obama, died on Tuesday at 84. Follow live.

4/4 Further, field replicates, when used as a proxy for the frequency of observation of a species through the seasons, yielded comparable temporal patterns to the ones extracted from the Global Biodiversity Information Facility (GBIF) for about 35% of investigated species.

3/4 We assessed if #eDNA can capture the temporal changes of #Ephemeroptera, #Plecoptera, #Trichoptera, and #Diptera.
We found pronounced, cyclic phenological trends in most groups: the communities diverged from spring to summer and then in fall gradually returned closer to the spring state.
2/4 ➡️ #Aquatic #insects are ecologically highly relevant in riverine systems & used in monitoring programs 📈 to assess ecological states.
➡️ Commonly, monitoring is conducted at 1–2 timepoints/y, despite known phenology of aquatic insect strongly affecting species presence/detection across seasons.

Dear Julie
apologies... to quick in copy-paste... hope it works now, otherwise DM!
thx for your interest
