The world is facing a biodiversity crisis. Nowhere is that more apparent than on oceanic islands where invasive species are a major threat for island biodiversity. Rats are one of the most detrimental of these and have been the target of numerous eradication programmes; a well-established conservation tool for island systems.
The impacts of house mice (Mus musculus), one of four invasive rodent species in New Zealand, are only clearly revealed on islands and fenced sanctuaries without rats and other invasive predators which suppress mouse populations, influence their behaviour, and confound their impacts. When the sole invasive mammal on islands, mice can reach high densities and influence ecosystems in similar ways to rats.
Following the incursion of rats (Rattus rattus) on Taukihepa (Big South Cape Island; 93.9 km²) off southern New Zealand in 1963, and the subsequent extirpation of several endemic species, the New Zealand Wildlife Service realised that, contrary to general belief at the time, introduced predators do not reach a natural balance with native species and that a safe breeding habitat for an increasing number of at risk species was urgently needed.
Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.
The Baja California Pacifc Islands, Mexico, are globally important breeding sites for 22 seabird species and subspecies. In the past, several populations were extirpated or reduced due to invasive mammals, human disturbance, and contaminants. Over the past two decades, we have removed invasive predators and, for the last decade, we have been implementing a Seabird Restoration Programme on eight groups of islands: Coronado, Todos Santos, San Martín, San Jerónimo, San Benito, Natividad, San Roque, and Asunción.
Considerable bene?ts can be achieved for indigenous biodiversity when invasive vertebrates are removed from islands. In New Zealand, two logistically challenging eradications were undertaken, one to remove cats (Felis catus) and the other Paci?c rats (Rattus exulans) from Te Hauturu-o-Toi/Little Barrier Island (Hauturu). Here we document the short- and long-term impacts of these interventions on the biodiversity of Hauturu. We also assess the extent to which predicted outcomes were re?ected in the measured responses for a wide range of species.
The traditional way of life has been, of necessity, an ecologically sustainable one. With care of the environment essential for future generations to benefit from the resources.
The objective of this study is to provide decision makers in the European Commission and other partner countries with sufficient information to identify European Commission cooperation activities with specific environmental objectives and to establish environmental safeguards for other activities.

The New Guinea mainland and surrounding islands possess an extra-ordinarily rich flora and a great diversity of vegetation types that parallel the diverse physiography of the lands and the resulting climates that prevail. A high proportion (some three-quarters) of the land area has a forest cover,
Ice, snow and climate change are closely linked. The Global Outlook for Ice and Snow investigates those linkages. It also presents information on the trends in ice and snow, the outlook for this century and beyond and the consequences to ecosystems and human well-being of these changes. It covers all parts of the cryosphere (the world of ice): snow, land ice, sea ice, river and lake ice, and frozen ground. The Global Outlook for Ice and Snow was written by more than 70 scientists from around the world.

Multilateral Environmental Agreements (MEAs) are a subset of the universe of international agreements. What distinguishes them from other agreements is their focus on environmental issues, their creation of binding international law, and their inclusion of multiple countries. Over the years, many MEAs have been negotiated and agreed at the international and regional levels. Some have a few Parties; some have almost global participation.
This report presents the results of a twelve day survey expedition (5 to 16 December, 2004) and represents the first ever systematic effort to document the marine biodiversity of the Great Sea Reef (GSR), locally known as Cakaulevu, to the north of Vanua Levu in the Fiji Archipelago. 23 sites were surveyed over 6 major habitat types: outer barrier reefs, back barrier reefs, channels, mangrove island fringing reefs, rocky island fringing reef and submerged patch reefs.

The Pacific islands are uniquely vulnerable to a variety of unpredictable events - natural disasters, including potential climate change impact, as well as health emergencies. The region is made up of mainly very small countries with poor socio-economic development. These and other contextual factors result in unique challenges in building systems, skills and experience necessary to maintain and promote a well functioning national society.
The Pacific Islands region faces increasing environmental and socioeconomic pressures exacerbated by global climate change and climate variability.1 Adaptation to climate change and variability (CCV) is ultimately an issue of sustainable development. Even without climate change, Pacific island countries are already severely affected by climate variability and extremes, and they remain extremely vulnerable to future changes in the regional climate that could increase the risks.
The natural environment of Pacific Island countries has supported, maintained and improved the social and economic wellbeing of its people and cultures since the arrival of the first inhabitants. The importance of the regions biodiversity cannot be understated; it is present in every facet of the island way of life. Natural resources provide food, shelter, medicine and are used extensively in traditions. In the past, utilization of these resources was allowed under traditional and community management.
Research shows that marine reserves are one tool that can help to prevent, slow, or reverse negative changes in the ocean. Marine reserves are places in the ocean that are completely and permanently protected from uses that remove animals and plants or alter their habitats. Increasingly, the public, governmental agencies, commercial groups, and scientists are discussing the idea of establishing more marine reserves to complement existing ocean management. The purpose of this report is to provide a summary of the latest scientific information about marine reserves.
The Asian Development Bank (ADB), in co-operation with the Government of New Zealand is formulating the Pacific Regional Environmental Strategy. This will review major environmental challenges in the region and put forward strategic objectives
and activities for ADB assistance.

This book comprises the offerings of sixteen indigenous Pacific writers and presents the first publication of its kind in the region in terms of profiling the direct experiences of Pacific indigenous communities who have had an acrimonious encounter with science, biotechnology and intellectual property rights
The study of marine sediments provides useful information in marine, environmental and geochemical research about pollution of the marine environment (Calace et al. 2005). Urban developments and industrial activities contribute to the introduction of significant amounts of contaminants (among them trace metals) into the marine environment and affect directly the coastal systems where they are often deposited (Angelidis 1995; Dassenakis et al. 2003).
This thesis is a critical ethnographic account of the Wartha people, a small group of hunter-horticulturalists living on the Torassi or Bensbach River, in the southwest corner of the Western Province of Papua New Guinea (PNG). This area is adjacent to the international border between PNG and Indonesia's Papua Province (West Papua).
