As ocean temperatures set new heat records, coral reef scientists are on a mission to identify which species and reefs can tolerate heat stress the best. But how and why do some corals cope with heat extremes better than others?
Length-weight parameters assist in the estimation of a fish’s biomass based upon assessment of length, providing value to many scientific and management applications. Some fish species have many sets of parameters published, while those less commonly studied may have no available information, making it challenging to decide which values to use. To address this, we present a database of quality-controlled length-weight parameters for 1,308 Pacific coral reef fish species from 87 families.
Global calls for greater ocean protection have sparked renewed interest in very large marine protected areas (VLMPAs, >100,000 km2) to achieve management targets; however, their conservation value is debated.
Today the world faces three interconnected crises: biodiversity loss, climate change, and unsustainable debt, each greatly exacerbating the other. Governments, Non-Governmental Organizations (NGOs), and Development Finance Institutions (DFIs) have increasingly focused on using commercial debt refinancing to simultaneously take action in support of conservation, build resilience to environmental change, and reduce or reprofile sovereign debt.
Crown-of-thorns seastars (COTS, Acanthaster spp.) are the most notorious coral predators, whose devastating outbreaks cause recurrent and extensive coral depletion across Indo-Pacific reefs. However, the spread potential of COTS outbreaks and the anthropogenic role in their initiation have remained a subject of intense debate for over five decades.
This study seeks to shed light on the rates and drivers of tree cover loss in island catchments focusing on a case study from Fiji. Global Forest Watch (GFW) is critically assessed as a framework for quantifying terrestrial tree cover loss and associated forest carbon stocks. The study assesses the role of the drivers of tree cover loss identified by GFW global models including anthropogenic deforestation: shifting agriculture, wildfires, urbanisation and plantation forestry as well as other drivers outside of the globally standardised list.
The Blue Carbon Finance Toolbox aims to provide the global blue carbon community with an overall guide to understanding and leveraging finance mechanisms that support the conservation, restoration, and sustainable management of blue carbon ecosystems.
If the ocean was a state of its own, it would be the seventh largest economy in the world – with a “gross marine product” of at least US$ 2.5 trillion per year. This Blue Economy is underpinned by diverse ecosystems that provide valuable services to the world, be it fishing, tourism or shipping. On the one hand, the ocean is undoubtedly an important part of the world economy. On the other hand, its asset base, that is to say its capital, is steadily declining. This is because the sea is a commons.

Marine spatial planning is underway now, or starting, in many Pacific Island countries, including Tonga. This planning aims, amongst other things, to achieve the Convention on Biological Diversity’s (CBD) Aichi Target 11 which states, in part, that at least 10 per cent of coastal and marine areas are conserved through ecologically representative and wellconnected systems of protected areas. However, means for countries who have signed on to the CBD to achieve an ecologically representative system of marine protected areas is missing.
