Storms in the Southern Ocean are producing more rain—and the consequences could be global
If you ever find yourself on Macquarie Island—a narrow, wind-lashed ridge halfway between Tasmania and Antarctica—the first thing you'll notice is the wildlife.

Evolutionary dynamics of dietary specialisation – insights from Neotropical mistletoe‐dependent frugivores
Mistletoes occur worldwide, with most relying on birds to disperse their sticky seeds to suitable hosts. There has been considerable ecological research on these interactions, emphasizing those birds....

Increasing tree cover in agricultural riparian buffers is linked to higher terrestrial biodiversity, with each 10% rise in forest cover supporting an additional vertebrate species.
Terrestrial biodiversity grows with tree cover in agricultural landscapes
Farmers plant or preserve riparian buffers for various reasons, such as improving water quality, controlling erosion, or maintaining hunting habitat.

Some stations broke their records twice
27.4C in Norfolk Island also broke its spring highest Temperature
But tomorrow summer cold records can fall in Tasmania and Victoria!

Long-term field data reveal warming cuts temperate forest NO and N₂O emissions by altering soil moisture
Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences and the University of California, Riverside, have investigated how the loss of forest soil gaseous nitrogen (NO, N2O, and N2) is affected by climate warming, highlighting the critical role of these gases in regulating forest nutrient cycling and ecosystem functioning.

Contemporary science redefines language as a dynamic, multimodal, and socially embedded system, moving beyond traditional speech-based frameworks to include sign, touch, and animal communication. doi.org/hbcv74
A 65-year-old linguistics framework challenged by modern research
In a re-evaluation of Hockett's foundational features that have long dominated linguistic theory—concepts like "arbitrariness," "duality of patterning," and "displacement"—an international team of linguists and cognitive scientists shows that modern science demands a radical shift in how we understand language and how it evolved.
