Happy #solstice! Today, beech trees start to decide whether to produce bumper seed crops next year, or to skip reproduction next year. It is a marker for growth and phenology processes. @micbog.bsky.social talked to The Guardian about how it works: www.theguardian.com/environment/...

Why the summer solstice is a ‘celestial starting gun’ for trees

Research shows longest day is a cue for beeches to launch their growth strategies

1/3: New paper: how do masting plants optimise the delay in reproduction? Having gaps (years) between reproductive events starves seed predators, increasing fitness. But they are also missed opportunities for reproduction. How do plants fine-tune the length of the time gaps to maximise fitness?

Breeding populations were younger in years that followed a higher beech crop 🌳🌳 – fitting evidence that this increases juvenile survival - and the relationship between masting and age structure was stronger when only assessing populations local to beech data collection. 5/n

Papers like this really underscore the importance of long term monitoring datasets for understanding climate change impacts on biodiversity... And highlight the dire consequences of even modest temperature increases. 🧪🌍🦤🦜 www.science.org/doi/10.1126/...

Climate change aggravates bird mortality in pristine tropical forests

Climate change threatens Amazon rainforest birds, with harsher dry seasons significantly affecting their survival over 27 years.

A remark from a referee ~40 yr back prompted this study. I launched it under the (later seen) wrong premise that it would last ~15 yr. But my marked plants lived much longer than anticipated, and it took me 38 yr to complete it. Here are the results. I defeated my plants in the race for survival.
