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

New paper on global change impacts on insects, out in GEB🦋🌍 Climate change and urbanisation act synergistically: butterfly declines are stronger under warming in urban environments. Species traits help explain heterogeneous responses. onlinelibrary.wiley.com/doi/10.1111/... @ylndmc.bsky.social

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...

🌆 Urban Ecology goes beyond the themed sessions! All week, check out additional presentations in: 📍 Seminarios 1 & 7, Auditorio, Balconada, and Cova dos Libros Hear @paucolom.bsky.social or @pauguzman.bsky.social ‪talking about butterflies 🦋 and @hernandezaguero.com on nature-based solutions 🌿🔧

Constantí Stefanescu summarises the results of 30 years of the Catalunya Butterfly Monitoring Scheme. Nearly 60% of species are declining significantly and only 10% increasing #FutureofButterflies

New paper with Erica Henry & @nickhaddad.bsky.social Q: What happens when butterflies, responding to climate warming, attempt an extra generation as summers get longer? A: Long-term monitoring shows overwinter population growth increases! 🧪🦋🐛https://onlinelibrary.wiley.com/doi/10.1111/ele.70018

"In conclusion, our results underscore the adverse impact of a zero-fire policy on insect communities, including fruit-feeding butterflies, within this unique ecosystem." Freire-Jr et al. 🧪🌍🌿🔥🌳 wildfire 🦋 onlinelibrary.wiley.com/doi/10.1111/...

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.

Cada vez más evidencias apuntan al declive global de las mariposas. Esta semana, un nuevo trabajo revela un declive generalizado en EEUU en las últimas dos décadas: www.science.org/doi/10.1126/.... Comentarios de colegas y míos sobre la situación en España y Europa: elpais.com/ciencia/2025...

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

[new paper] EuPPollNet: A European Database of Plant-Pollinator Networks onlinelibrary.wiley.com/doi/10.1111/... Another wonderful paper of @joseblanuza.bsky.social making open more than >1500 networks and looking at their properties. Come for the data, stay for the cool figures!

How does local climate influence ecological communities? Answer: #Thermophilisation caused by #colonisation and local #extinction. Check out the new paper by @guim091.bsky.social on #mountain #butterflies in Central Spain. #ClimateChange #Refugia doi.org/10.1111/ddi....

This post by @jeffollerton.bsky.social shows we had online plant-pollinator databases since 1995!! jeffollerton.co.uk/2025/01/07/w... The next big one is coming soon, lead by @joseblanuza.bsky.social within the #safeguard pollinators project with more than 1000 networks

Arrived!! @callejas.bsky.social @paucolom.bsky.social
