On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperat...

Our new review is finally out! 🌿 I’m especially excited because this is the first chapter of my PhD!
Have a read to see what shapes the range limits of alpine plants besides freezing temperatures ❄️

Webropol Survey Survey Powered by Webropol

🌎 Experiments are central to understanding community dynamics, yet their use is declining.
We're trying to understand why.
If you work in community ecology, we'd really appreciate your input in a quick survey (<5 mins).

Bee assemblage data from 681 crop fields across 3 continents shows that local pesticide hazards and decreasing adjacent semi-natural habitats negatively affected wild bee abundance and species richness in crop fields, while pesticides reduce functional diversity🧪🐝 www.nature.com/articles/s41...

Proud friend moment ❤️ @agostinatorres.bsky.social The fact that I am not in BES does not mean I can be proud virtually 🤓 Thanks to onsite photo providers 😜 @mikkotiusanen.bsky.social

So happy to be back at the BES this year for #BES2025! I had a lot of nice discussions today already, and I'll be looking forward to the poster session this evening! Feel free to pass by poster nr: A-4.95 if you want to discuss species coexistence and higher-order interactions! 🌱🌿🌱

Welcome to BES2025! 💫 

Today, we are so excited to welcome ecologists from 58 countries, encouraging innovative research and practice in ecology. 

We have exciting talks and sessions ahead in the next days from agriculture, human's place in nature, AI to green finance and much more.

Onnea uusiin seikkailuihin!

Announcement: I will start as an assistant professor of ecohydrology at the University of Oulu starting from January. Snow, microclimate and Arctic-alpine ecosystems still on focus. Stay tuned for soon-to-be-opened Postdoc and PhD positions! Thank you for your attention to this matter!

Resource supplementation later in the colony cycle improves real‐world bumblebee colony survival Our findings suggest that B. terrestris colonies became food-limited towards the end of their colony cycle in early summer. We suggest ecological intensification through planting native wildflower sp....

How do we do more with biodiversity data we've already collected?

I gave a TED Talk on scientific discovery in ecological databases at a joint TED Countdown and Bezos Earth Fund event for #NYClimateWeek this year, and it's now live!

Herbivory Modifies the Role of Spatial Processes in a Grassland Plant Metacommunity We empirically examined how mammalian herbivory interacts with habitat size and connectivity to affect plant diversity in a natural grassland metacommunity. We found that herbivory increased plant di...

New study out in Ecology Letters 🌱🐑!

Using long-term Åland monitoring data, we found that herbivory increases plant diversity across scales and flips the diversity–area relationship: a positive relationship is found in grazed sites while a negative one in ungrazed sites.

Pollinator contribution to crop production: a temporal and economic assessment in Portugal - Regional Environmental Change Pollination is a key ecosystem service that supports agriculture and food security, with significant economic relevance. Yet, national-scale assessments remain scarce, despite their critical role in i...

🐝 Pollinators are worth billions. A new study from the FLOWer Lab shows they secure over €2B/year for PT agriculture, with €1.1B coming from wild pollinators. Protecting them is essential for our food, economy and future.

Are you involved in ecological forecasting in Europe?
We’re mapping forecasting applications across the continent — from SDMs to observatories with predictive potential.
Our goal: make EU forecasting more connected and identify both immediate and long-term forecasting potential.

🌼🌡️ 🐝 Thermal conditions can directly reshape species interaction networks under climate change.

⬇️ In this invited short piece, I discuss how temperature-driven shifts in pollinators’ foraging choices, revealed by a new study, can cascade through entire plant–pollinator networks.

🌷New Research highlight showcases Arrowsmith et al. (2025), which shows that temperature alone can shift pollinators’ floral choices in diverse plant–pollinator communities. Such thermally-driven species interaction rewiring may have important consequences. ➡️ buff.ly/i5QrFjd

Pollinators such as wild #bees, #butterflies, and #hoverflies are in trouble worldwide. A major new study, published in Science, shows that the oft-quoted figure of 10% semi-natural habitat in farmland landscapes is far too little to safeguard pollinators
