Those savannas next to the river that experienced flooding a few months ago are now ready to burn (flood-sensitive grasses); savannas further from the river are green (non-flammable).
Flooding enhances fire, i.e., water and fire are complementary forces in Los Llanos del Orinoco, Colombia.

Savanna with all the grasses dead, although we are not in the dry season. This savanna is close to the river and was flooded a few months ago

Where does pollen go after leaving a flower? Our paper on pollen fates in buzz pollinated flowers is out. Congrats to the three brilliant undergrads that carried out this study from beginning to end!

Experts on wildfires are posting about the fires in the northern part of Iberia, because fires there right now are remarkably large and numerous. But the causes are the same as in any Mediterranean environment. The thread below explains the complexity and why we need to adapt (in Spanish).

¿Por qué la región entre Zamora, León y Ourense arde tanto?
No, no es para construir aerogeneradores, ni por ninguna de las teorías conspiranoicas que estamos leyendo. La explicación es más compleja… y menos cómoda para quienes buscan respuestas simples. 1/13

An article I wrote for @theconversation.com in response to #allotment sell-offs. Featuring evidence from myself and @davegoulson.bsky.social and the amazing work led by Jill Edmondson's team at Sheffield. #communitygardens #urbanbiodiversity #growyourown

Having Sir David Attenborough narrate a story based on our findings on the dyeing poison frog was something that I never imagined, even in my wildest dreams. Now it’s happening, in the new BBC series “Parenthood” (Episode on Freshwater)! 🤩 www.youtube.com/watch?v=1Zih...

🥕 Are you a UK researcher or practitioner working in urban agriculture? Please join us at 'Growing Together: A Transdisciplinary Forum on UK Urban Food Systems'
📅17-18th September 2025
📍University of Sussex
✍️Register by 31st Aug: lnkd.in/eQHbQxP2
❓More info? Contact: [email protected]
A poster advertising the eventnb with images of home growing and a QR code in the bottom right corner to scan to register. The Text reads: This interdisciplinary two-day event will bring together researchers, practitioners, and policymakers to:
•	Map current UK urban agriculture research
•	Identify knowledge gaps and shared priorities
•	Foster new collaborations for future projects and funding
 
A second page of the poster advertising the event. This provides a schedule for the day, including three panel sessions on Diversity, Governance and Community on Day 1, 17th September, and a faciliated workshop to focus on research priorities, synergies and knowledge gaps and a visit to Moulsecoomb Forest Garden. The bottom half of the poster has photos of speakers.

Paying attention to the correct sequence of numbers is important! Find out why in this freshly published paper by Symington & Rockx: A pervasive typographical error in an equation for calculating nectar density is likely to have limited consequences - doi.org/10.26786/192...

Trait–fire mismatching. Illustrative examples of mismatch are shown where anthropogenic shifts in fire patterns have plausibly reduced plant fitness. Trait–fire mismatching in animals. A conceptual overview of how trait–fire mismatches are defined and measured, and a few examples.
