Increasing tree mortality over time in Australian forests

www.nature.com/articles/s41...

Pervasive increase in tree mortality across the Australian continent - Nature Plants

Eight decades of forest plot monitoring show a pervasive increase in tree mortality across Australia’s forest biomes driven by climate change, jeopardizing their role as enduring carbon sinks.

Biodiversity enhances the positive effect of structural diversity on forest productivity and indirectly boosts productivity through structural diversity🌍

However, environmental stressors weaken the positive impact of structural diversity🐘

🚨New paper!🚨 Models predict trees like beech will migrate north as climate warms, but rarely consider tree reproduction. Jessie shows these “refuges” are exactly where climate warming will disrupt seed production the most. They may not be such great climate refuges after all.

Earth's largest land animals are limited by salt.

Sodium availability constrains the density and distribution of elephants, giraffes and rhinos across Africa, and offers a new explanation for the so-called 'missing megaherbivores'.
