A 33-year study on Costa Rica’s white-faced capuchin monkeys reveals that extreme climate events force the primates to abandon their social norms. Severe droughts cause food scarcity, driving intense competition, territorial sensitivity and shifting group dynamics. Adam Litchkofski reports.

It is also relevant for pasture design and seed mixture selection 📜🌱 If individual cows differ in their preferences and requirements, diverse multispecies grasslands may give them more opportunities to select their own diet. (You are almost there 💪 One more post, the last picture is the best!)

In other words, cows within the same herd do not necessarily use a pasture in the same way. This is something to consider when interpreting grazing behaviour based on herd-level results.

The excursion took place during a heatwave, making one thing obvious: the shade provided by trees benefits not only livestock but also people. A nice reminder that agroforestry is becoming increasingly relevant in a warming climate. Looking forward to the next #EURAF conference! Who knows where...

🚌 The conference also included a field excursion to the famous wooded pastures of the Jura Mountains. We visited a traditional farm, and a farm planting increasing numbers of trees to help adapt to climate change. It was a great opportunity to see agroforestry in practice.

What this study suggests 👇 • The Hohenheim Gas Test may help compare individuals, not only feeds • Condensed tannins may mainly act in the short term (when ingested with feed) • Diverse mountain pastures may select a more fibrolytic rumen microbiota 4/4

The higher condensed tannin content of alpine pastures did *not* reduce methanogenesis as expected. Genotype effects were significant, but smaller than those of the feeding system🐄🐂 This highlights how strongly feeding environments shape rumen function. 3/4

Have you heard the propaganda about how C02 pollution is "plant food"? Yes, it causes crops to grow faster and produce higher yields, but it also means there's more sugar and fewer nutrients. Fossil fuels damage food supplies at a time when billions are already suffering from nutrient deficiency.
