Climate warming is not a recent phenomenon; it has had detectable impacts on plants for at least 134 years!

Phenology changes for the Japanese cherry tree (Prunus jamasakura) in Kyoto. Left: Day of the year of the flowering peak for the period between 812 and 2024. Right: Relation between March mean air temperature (°C) in Kyoto and the day of the year of the Japanese cherry tree peak flowering for the period between 1890 and 2024. https://jgpausas.blogs.uv.es/2025/06/11/134-years-of-climate-warming-effects/

Fire buffers drought impacts on reproduction in a resprouting shrub
nsojournals.onlinelibrary.wiley.com/doi/10.1002/...

Under drought, burned plants had ⬆️prob. of flowering, produced +flowers, set +seeds & heavier seeds, than unburned
Saiz-Blanco et al @oikosjournal.bsky.social

🧪🌍🔥🌿🪴🌾🌱 Anthyllis
One of the graphics of the paper on Anthyllis cytisoides resprouiting after drought, showing model predictions and observations of the data analysed in 2022 and 2023; fire occurred in 2021. For flowering and fruiting, the negative effects of drought are stronger on unburned plants (A and C). Burned plants produced nearly four times more flowers than unburned plants (B), and had a higher seed set and heavier seeds than unburned plants in both years (D and E).

El zorro es un eficaz dispersor del palmito (Chamaerops humilis). En su costumbre de visitar y marcar las letrinas de conejo con sus excrementos (📷 blanco), favorece la germinación del palmito (📷 amarillo) en un entorno muy ramoneado por conejos. Estas plántulas tienen baja prob. de prosperar aquí.

Molt bé. Els tècnics han fet molt bon treball; dona gust veure'ls fer una crema de precisió. Respecte a la vegetació, ha cremat diferent que com ho hagués fet a l'estiu, però vaja, tot bé.

🔥 Un estudio con participación del @csic.es señala que la combinación de ola de calor extrema y vegetación inflamable fue clave en los incendios récord de 2025 en el noroeste peninsular.

📍 El 2 % del territorio europeo concentró >50 % del área quemada en la UE.

Yes, it is interesting to note Wallace's exceptional modesty, which may explain why the term 'Wallace-Darwin theory' is not commonly used (unlike Lotka-Volterra model, Janzen-Connell hypothesis, ...)

Chu et al. (urls.fr/Yeo6-K) estimate that cats kill ~60 million birds per year in Canada (possibly up to 197 M). Outdoor cats pose a serious risk to native birds. Potential responses include bylaws, education, social engagement, and trap-neuter-release programs. Think about it if you own a cat 🧪🌿🌎🦉🦊

Do you know that many palms are acaulescent (without stems)? The APALM database lists 216 acaulescent palms. They have rizomes (geophyte palms!) & thus are very resilient to disturbances. By da Silva et al.

Remember, when we talk about chemicals, the exact concentration or units are not the critical factor; what matters is their biological effect (eg, 0.02% cyanide in the air kills you in a few minutes!).
