Towards a global butterfly index! 🦋🌍 Despite data gaps in many regions, butterflies are among the best candidates to build a global indicator for insects Long-term monitoring —like CBMS— is key 👉📄 Check out the scientific article: conbio.onlinelibrary.wiley.com/doi/10.1111/...

Cap a un índex global de papallones! 🦋🌍 Tot i els buits de dades a moltes regions, les papallones són un dels millors candidats per construir un indicador global pels insectes El seguiment a llarg termini —com el CBMS— és clau 🔗 Notícia (cat): l1nq.com/A1UsG 📄 Article (eng): l1nq.com/ylK12

New study on arthropod declines @natecoevo.nature.com 🪲 In two time series @jena-experiment.bsky.social & @bexplo.bsky.social we show how community (dis)assembly underpins local biomass declines. It mostly boils down to species loss, with identity losing relevance. www.nature.com/articles/s41...

Did you know we also record butterfly–flower interactions? 🦋🌸 Three decades of observations show how species loss limits the capacity of communities to reorganize their interactions in response to environmental change. 📄Read the scientific article: l1nq.com/L5wls

Sabies que també comptam interaccions papallona-flor? 🦋🌸 Tres dècades d'observacions mostren com la pèrdua d’espècies limita la capacitat de les comunitats per reorganitzar les seves interaccions davant els canvis ambientals. 🔗Notícia (cat): l1nq.com/KBoEF 📄Article científic (eng): l1nq.com/L5wls

Un estudi recent liderat per @paucolom.bsky.social i amb participació de @ylndmc.bsky.social del @creaf.cat constata, entre altres coses, que la urbanització intensifica els impactes del #canviclimàtic en les poblacions de #papallones 🧵👇

We’re missing a global indicator to track insects. By analyzing thousands of butterfly populations, we highlight both promising signals and key challenges—showing why these taxa are strong candidates for building a Global Index to support conservation. conbio.onlinelibrary.wiley.com/doi/10.1111/...

Looks like a fundamental study and approach ... Limited thermal tolerance in tropical insects and its genomic signature. Insects at high elevations utilize plasticity to cope with rising temperatures, whereas lowland species have limited plastic abilities. www.nature.com/articles/s41... 🧪🌐

This February I’ve been sharing results from our new study on temporal interaction turnover and its links to climate change and species loss. Presented at @ecoflor.bsky.social 🌼 and the CBMS meeting 🦋 And the month ends with great news: the paper has been accepted in Ecology Letters! 🎉

New paper out today (my final PhD chapter)! Increasing impervious surfaces strongly reduces cavity-nesting bee and wasp communities, and flower patches alone showed no detectable impact. @aer-ese-bes.bsky.social #openaccess besjournals.onlinelibrary.wiley.com/doi/10.1002/...

We just released the latest update of the European Grassland Butterfly Indicator. doi.org/10.5281/zeno... With nearly 50% decline since 1991 and the decline not reversing, this is again an urgent call for actions for bending the curve, restore habitat and protect biodiversity

Now online! In this review, we cover four major topics on butterflies and moths: their evolutionary history and diversification dynamics, genomics, global diversity patterns, and conservation 🦋🌏 (1/8) @natrevbiodiv.nature.com www.nature.com/articles/s44...

Davant l’augment de les temperatures, conservar microclimes favorables pot marcar la diferència entre l’extinció local i la persistència d’una espècie. Hi ha grans solucions als mons petits que també ens beneficien els humans. ✍️ @jdiazcalafat.bsky.social, @uib.cat @culturacientifica.uib.cat

More bad news for butterflies. Our new paper led by Wendy Leuenberger shows common species are declining even more rapidly than rare ones. @ZipkinLab Three decades of declines restructure butterfly communities in the Midwestern United States | PNAS www.pnas.org/doi/10.1073/pnas.2501340122
