Leachate from microplastics impairs larval development in brown mussels

Microplastic debris is a pervasive type of contaminant in marine ecosystems, being considered a major threat to marine biota. One of the problems of microplastics is that they can adsorb contaminants in extremely high concentrations. When released from the particle, these contaminants have the potential to cause toxic effects in the biota. So far, reports of toxic effects are mostly linked with the direct exposure of organisms through ingestion of contaminated microplastics. There is little information on the toxicity of leachates from microplastics to marine organisms. In this study, we conducted experiments to evaluate the toxicity of leachates from virgin and beached plastic pellets to embryo development of the brown mussel (Perna perna). We compared the efficiency of two test procedures, and evaluated the toxicity of beached pellets collected in a coastal marine protected area.We observed that mussel embryo is sensitive to leachate from both virgin and beached pellets. However, the toxicity of the leachate from beached pellets was much higher than that of virgin pellets.We suggest contaminants adsorbed onto the surface of beached pellets were responsible for the high toxicity of leachate from beached pellets, while the toxicity of leachate from virgin pellets was mainly due to plastic additives. Our results suggest microplastic debris may be harmful even if ingestion is not the only or main pathway of interaction of marine organisms with contaminated plastic debris.

The EU Biodiversity for Life Flagship Initiative

European Union

The EU has long supported biodiversity con- servation and recognised the links between healthy ecosystems and livelihoods. Starting from the mid-1980s, the EU has helped devel- oping countries manage biological resources in a sustainable way. It has provided long-stand- ing support to biodiversity conservation in National Parks and protected areas, especially in Africa, by increasing the capacity of local authorities and NGOs in management and finance, monitoring and evaluation, and in pro- moting income-generating activities compat- ible with conservation. The best-known action of this kind is the Conservation and Rational Use of Forest Ecosystems in Central Africa Pro- gramme (ECOFAC), which protects the habitats of great apes and other emblematic species and ecosystems. The EU has invested nearly EUR 140 million in ECOFAC since 1992, sup- porting 16 major protected areas in eight Cen- tral African countries, covering an area of more than 130 000 square kilometres.

Taking conservation connectivity to scale; strengthening resilience at landscape and seascape scales

Island and Ocean Ecosystems

UNEP

Across the world, multiple drivers of change are causing the degradation, fragmentation and loss of natural habitats on land and in the worlds oceans. As a result, important conservation areas for biodiversity and ecosystem services are becoming increasingly isolated within a matrix of human dominated landscapes and seascapes. This isolation can prevent the movement of organisms essential for the maintenance of biodiversity and disrupt ecological processes necessary for the provision of vital ecosystem services. Fragmentation and degradation also reduce options for adapting to global change, thereby undermining resilience of ecosystems and people.

Ka'ai'ai, Charles

More often than not, economically deprived countries and indigenous communities are the owners and stewards of the world's natural resources. For the poorest of poor, direct access to nature is their lifeline. But globalization has centralized wealth and reduced the poor's access to economic opportunity. For native communities, the return of economic benefits has been slow as has acknowledgement of the vast traditional knowledge that they hold on managing and utilizing their unique island resources.

Island and Ocean Ecosystems

Pacific Community (SPC)

The Pacific Community Strategic Plan 2016-2020 sets out our organisation's strategic direction and priorities. The Pacific Community (SPC) recognises that our programmes and services need to consider the changing development landscape at national, regional and global levels. As a key institution in the regional architecture of organisations supporting the Pacific, our programmes must reflect the strategic direction set out in the Framework for Pacific Regionalism, the regional priorities identified in the SAMOA Pathway and the commitments in the Sustainable Development Goals.

Pacific Islands Trade 2010 to 2014

Hughes, Sally Ann

Kamea, John

Trade is an important component of growth and development in the Pacific Islands. Export revenue not only contributes to the balance of trade but also to each nation's gross domestic product (GDP). Food security is also impacted by the level of imports of food products.

Pacific Community (SPC)

This report presents an overview of the contribution that the Secretariat of the Pacific Community (SCP) makes through its work in the Pacific Island region. It also describes SPC's progress towards achieving the specific organisational objectives set out in its Corporate Strategic Plan 2013-2015, which include a more integrated way of working. SPC's regional and subregional work complements country-specific work carried out in cooperation with each island member.
