Always happy to do outreach on butterfly monitoring and conservation 🦋 Why do we count butterflies—and how do we do it? Spreading the word in Mallorca!

🦋 New general results section on the CBMS website! 📊📉 Explore how butterflies are changing in Catalonia: local and regional trends, cumulative changes in abundance, and multi-species indicators... 🌐👉 www.catalanbms.org/ca/resultats...

🦋 Nova secció de resultats generals al web del CBMS! 📊 📉 Hi pots explorar les tendències de les papallones a diferents escales (local i regional), els canvis acumulats d’abundància al llarg del temps i diversos indicadors multiespecífics... 🌐👉 www.catalanbms.org/ca/resultats...

🏔️🐄 Long-term grazing shapes butterfly diversity in the Pyrenees ⚖️ Butterfly diversity peaks under moderate grazing 📉 Overgrazing or grassland abandonment → butterfly decline 🌿🦋 More plants → more butterflies (particularly specialists) 📄 Check out the paper: l1nq.com/uhj9m4t

🏔️🐄 La pastura a llarg termini determina la diversitat de papallones als Pirineus ⚖️ La diversitat és màxima amb una gestió moderada 📉 Sobreepastura o abandonament → menys papallones 🌿🦋 Més plantes → més papallones 🔗 Notícia (cat): sl1nk.com/h3ezhle 📄 Article (eng): l1nq.com/uhj9m4t

A fitting tribute to a great man. He did so much to help us understand and conserve butterflies. He leaves us with some crucial knowledge to face the future

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 🧵👇

Les confons sovint? Tenim la solució 🦋 Hem recopilat en un sol document totes les fitxes d'identificació publicades als 17 números de la revista Cynthia des del 2001. Més de 100 especies incloses! 👉 Descarrega el dossier complet: www.catalanbms.org/ca/recursos/

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/...

New study on temporal interaction turnover using a unique dataset 🦋🪷 Communities adapt to climate fluctuations through rewiring. But over the long term, as species are lost, rewiring declines—reducing the capacity of communities to buffer environmental change onlinelibrary.wiley.com/doi/epdf/10....

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

Five 3-year Postdoc positions open at @ebdonana.bsky.social. I am happy to sponsor and mentor good candidates working in my field, but note that these are quite independent positions aimed at helping stabilize new researchers in the system. www.dropbox.com/scl/fi/4nqkq...

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

A full report of our latest European Grassland Index has just been published. It gives individual species trends as well as the overall decline of 50% since 1991-2023. Another update will be coming soon to include 2024 (which was not a good year for many butterflies) doi.org/10.5281/zeno...

IMHO, given the international political havoc and the attacks on the US science system, the EU had a chance to be smart—investing in an ambitious plan to attract international talent to our R&D system. Instead, we fell into the trap and chose to buy more weapons. www.politico.eu/article/ursu...

In a review led by Spanish researchers David Peris and Ricardo Pérez-de la Fuente, we explored why a deep time perspective on insect pollination is relevant to our current understanding of plant-pollinator relationships. Read more here: jeffollerton.co.uk/2025/03/12/e... #pollinators #biodiversity

Our latest Activity Report is now available on our website. It shows the amazing growth of the European Butterfly Monitoring Scheme and some exciting projects now underway to help slow the decline of butterflies, moths and other pollinators assets.vlinderstichting.nl/docs/28d3ebc...

I'm so excited to share my new Science publication documenting the decline of butterflies across the USA!! The bottom line is that we saw widespread, concerning declines between 2000 and 2020: 22% reduction in total numbers of butterflies, 33% of species declined while less than 3% increased.

That feeling when you achieve excellence but still fall short. Sometimes the ball hits the net and falls on the wrong side. I guess that's part of the game. Let's keep pushing! #MCSA2024
