七国集团（G7）环境部长在巴黎举行的为期两天的会议上宣布取得进展，尽管为了避免与美国产生摩擦，会议议程中排除了气候变化议题。法国生态部长莫妮克·巴尔比（Monique Barbut）表示，这种寻求共识的务实做法促成了七项声明的发表。

Researchers have used a synchrotron particle accelerator, robotics, and AI to create high-resolution 3D models of ants from 800 species. The project scanned 2,000 specimens in just one week, far faster than traditional methods. This effort, called Antscan, aims to build a digital library of insect biodiversity.

A Uerj study shows that the jackfruit tree, an invasive species in the Atlantic Forest, reduces leaf litter depth and arthropod abundance, affecting various frog species. Areas dominated by the tree feature simpler habitats, with varied impacts on wildlife. Published in Biological Invasions, the research emphasizes the need for management to restore ecological complexity.

Pollinators like bees and butterflies are essential for global food production but face severe decline due to habitat loss and pesticides. A recent assessment highlights that over one in five North American pollinators risks extinction. Home gardeners can help by planting native species to provide critical nectar sources.

A comprehensive study of over 31,000 tree species worldwide indicates that forests are becoming more uniform, with fast-growing trees gaining dominance while slow-growing, long-lived species decline. This transformation threatens ecosystem stability, carbon storage, and biodiversity, particularly in tropical regions. Scientists urge changes in forest management to protect vulnerable native trees.
