While biodiversity is being reshaped across the globe, extinction risk assessments are lacking for most species, and a major challenge remains in understanding whether global threat status aligns with local population trends. Here, we assess whether population temporal prevalence trends are consistent with a species’ global extinction risk, using over 60,000 populations of 2362 species across 978 marine and terrestrial assemblages (sampled for at least 20 years, mostly from temperate regions).

Protected areas are a critical component of efforts to reverse biodiversity loss by 2050. In the ocean, free-driftingfish aggregating devices (dFADs) are released in large numbers by industrial purse seine fishing companies tohelp catch tuna. These devices can enter marine protected areas (MPAs) undetected, potentially leading to wildlifeentanglement, plastic pollution, and habitat degradation. Here we investigate processes by which dFADs maycompromise MPA objectives and assess the burden they put on existing MPAs.

Target 3 of the Kunming-Montreal Global Biodiversity Framework aims to increase global protected and conserved area coverage to at least 30% by 2030. The impact on people, whether positive or negative, will depend on the social context of additional areas and how they are governed and managed. Here, we show that Target 3 could affect large and socially diverse populations under different implementation scenarios. Nearly half the human population lives within 10 km of areas included in a scenario maximising biodiversity representation.

Over the past two decades, there has been a growing global interest in understanding and demonstrating the effectiveness of protected areas (PAs) and other effective area-based conservation measures (OECMs) which collectively are referred to as protected and conserved areas (PCAs). The need to go beyond coverage targets and understand whether PCAs are delivering conservation outcomes was already recognized in the Convention on Biological Diversity’s Aichi Target 11, which highlighted that PCAs must be “effectively and equitably managed” (CBD 2011).

The ocean is home to some of the richest biodiversity on Earth. From coral reefs and mangrove forests to the deep sea, marine ecosystems sustain countless species, support coastal communities, regulate the climate and underpin global food security.But these systems face growing pressure from overfishing, habitat loss, pollution and climate change.

A landmark global study has identified more than 165,000 square kilometres of coral reefs across 71 countries with the strongest potential to survive a warming world – tripling previous estimates and offering a rare note of hope for one of the ocean’s most threatened ecosystems.

The reef manta ray (Mobula alfredi) is a highly mobile pelagic marine ray found throughout the tropical and subtropical waters of the Indo-Pacific, but investigation into their behavior and ecology within Papua New Guinea has not been previously undertaken. Furthermore, the home range, dispersal characteristics, and inter-seasonal fine-scale habitat use of this species is limited.

ndonesia’s fisheries are vast, worth billions of dollars and sustaining millions of people. They are also under threat from overfishing, bottom trawling, destructive fishing practices, mangrove conversion, and a changing climate. Local governance matters in combatting these issues. We see this in the recovery of reefs and the return of life to coastal areas managed by local people in West Kalimantan where my organisation works. These fish and crustaceans spill over into adjacent waters, benefiting even more fishers.

Perched on the bow of an aluminum landing craft, Anne Cohen gazed a few yards ahead of the vessel toward a yellow robot gliding across the emerald Majuro lagoon. The unmanned surface vehicle, called Yellowfin, was quickly becoming one of the coral researcher’s most dependable guides in these Central Pacific waters.
