Bending back the curve of shark and ray biodiversity loss

Sharks and rays are sentinels of the state of the ocean. Since the mid-twentieth century, overall abundance has declined by nearly 65% and over one-third (37.5%) of species are threatened, causing widespread changes in community structure. This crisis stems from unregulated fisheries expansion coupled with inadequate catch-and-trade monitoring that fail to account for the complexity of shark and ray products, their use and global trade flows.

Litter accumulation in tropical mangroves threatens biodiversity and local communities

Mangroves, typical of tropical and subtropical latitudes, have become veritable natural traps for land- and sea-based waste. The roots of these trees, known as mangroves, have a great capacity to trap litter—from both land and sea—which gradually breaks down until it is buried in the muddy bottom.

How to ensure social outcomes in restoration

Effective restoration projects must generate meaningful benefits for both nature and people. While ecological gains are often well-documented, social outcomes — such as livelihoods, governance, well-being, equity, and cultural identity — are still less consistently measured and integrated across restoration literature and practice. This brief outlines why social outcomes matter and how to ensure

Socio-environmental movements emerge as key global guardians of biodiversity amid rising violence

A new study published in the Proceedings of the National Academy of Sciences reveals that organized civil society and social mobilization are key, yet often unrecognized, agents of global biodiversity conservation. By analyzing a global dataset of 2,801 socio-environmental mobilizations from the Environmental Justice Atlas (EJAtlas), the research identifies that local struggles against polluting industries are critical for protecting the planet's most sensitive, biodiverse regions.

Ocean Travellers: Safeguarding Critical Habitats For Migratory Sharks And Rays

This report presents the first global overview of Important Shark and Ray Areas (ISRAs) for species listed under the Convention on the Conservation of Migratory Species of Wild Animals (CMS) and its daughter agreement, the Memorandum of Understanding for the Conservation of Migratory Sharks (Sharks MOU). ISRAs are identified through a standardized, expert-driven process to map habitats essential for shark, ray, and chimaera species.

Guidebook for assessing and improving social equity in marine conservation

his guidebook is based on an understanding that social equity refers to fairness and justice with respect to the ways that people are recognised, treated, or impacted by conservation initiatives. It is also grounded on a common framework for assessing equity that includes six dimensions: recognitional, procedural, management, environmental, distributional, and contextual and structural equity.

Ants need urgent protections from global trade, conservationists say

As the recent seizure of more than 5,000 endemic ants in Kenya reveals, ants have become part of a thriving global wildlife trade. Transnational traffickers are mopping up ants from the wild to sell them to hobbyists and collectors worldwide. In a recently published letter, conservationists are now calling for greater trade protections for all ant species under CITES, the global wildlife trade treaty.

The impact of tropical cyclones Pam, Harold, Winston and Yasa on tree cover loss in Vanuatu and Fiji

Many Pacific Small Island Developing States are vulnerable to Tropical Cyclones (TCs) leading to an estimated average annual loss of USD 1.08 billion. The study quantifies the impacts of tropical cyclones on tree cover and associated ecosystem services, beginning with coastal protection and the loss of carbon, for inclusion in Post Disaster Needs Assessment (PDNAs), Nationally Determined Contributions (NDCs), catastrophe risk insurance payments and loss and damage accounting.

Marine protected areas as living labs? Lessons learned & future perspectives

Marine Protected Areas (MPAs) management usually involves bringing multiple stakeholders together, to construct policy-relevant research programs and science-based tools for adaptive management. Here, we present the conclusions of a transdisciplinary workshop that aimed at reviewing experiences in the co-design of EBM research in MPAs. We find that MPAs represent powerful instruments for conducting real-world experiments, de facto acting as living labs in support of ocean governance.
