Study challenges narrative of accelerating extinction rates

A new analysis of 500 years of extinction data reveals that species losses peaked about a century ago and have since declined, contradicting assumptions of a rapidly worsening crisis. Researchers from the University of Arizona found that past extinctions were mainly driven by invasive species on islands, while current threats center on habitat destruction on continents. The study emphasizes the need for accurate assessments to inform conservation efforts.

North Atlantic dolphins facing shorter lifespans due to bycatch

Common dolphins in the North Atlantic are dying much younger, with female lifespans dropping seven years since the 1990s, according to a new study. Researchers analyzing stranded dolphins in the Bay of Biscay highlight bycatch from fishing as a key threat, urging better conservation measures. The findings reveal a 2.4% slowdown in population growth, signaling risks to marine ecosystems.

European institutions launch campaign for International Coccolithophore Day

2025년 10월 11일 AI에 의해 보고됨

Five European research institutions have announced an initiative to establish October 10 as International Coccolithophore Day, highlighting the crucial role of these microscopic plankton in regulating Earth's climate. Coccolithophores, tiny algae smaller than dust grains, capture carbon dioxide, produce oxygen, and form geological records of climate history. The campaign aims to raise awareness of their impact on ocean ecosystems amid climate change threats.

Deep-Sea Worms Tolerate High Arsenic

Researchers revealed on September 6, 2025, the discovery of deep-sea worms capable of tolerating high levels of arsenic, expanding knowledge of extremophile adaptations. This finding uncovers new biological mechanisms for toxin resistance. It was reported alongside other marine science updates.
