Researchers advocate for ocean-centered governance to resolve crises and foster harmony with humanity. The Earth Law Center and other experts propose introducing rights to the ocean.
High plant diversity is often found in the smallest of areas
Researchers analyzed 170,000 vegetation plots from all climate zones to find that small areas can have high biodiversity, like Eastern European steppes and Siberia. This challenges the idea of large-scale conservation, as smaller protected zones may be more effective in preserving ecosystems.
Invasive wasp tests nature’s strengths and weaknesses
Research on the invasive Sirex woodwasp estimates it can reproduce up to 2-3 times higher in North America than in its native range, posing a significant threat to local ecosystems. The wasp's ability to tolerate climate extremes and spread rapidly makes it a challenging insect to control.
Researchers identify ancient bird behind giant eggs from Down Under
A team of researchers has identified the ancient bird species behind giant prehistoric eggs in Australia, resolving a years-long debate. The study found that the eggs belonged to a unique duck-like line of megafauna known as the 'Demon Ducks of Doom', which was laid by the Genyornis newtoni bird.
