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.

To formally launch the second phase of the Biodiversity and Protected Areas Management (BIOPAMA) programme, a regional inception workshop for the Pacific was held at the Tanoa Tusitala Hotel, Apia, Samoa from 11th to 15th June 2018. The aim of the inception workshop was to ensure that all 15 countries in the Pacific ACP Group of States were engaged for the second phase of BIOPAMA. The working title of the workshop was Regional Workshop on Improving Information and Capacity for More Effective Protected Area Management and Governance in the Pacific.
The Pacific region has benefited from a number of regional and national programmes to both assess the impacts of climate change on biodiversity and develop programmes to adapt to climate change. Such programmes are critical considering that the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) 1/ states that the Pacific region has already experienced temperature increases of as much as 1°C since 1910.
Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.
Tongas marine ecosystems are worth at least TOP 47 million per year, exceeding the countrys total export value. We are strongly committed to sustaining these values to build an equitable and prosperous blue economy.

Kwajalein is a crescent-shaped atoll that lies between 09°25' and 08°40'N and between 166°50' and 167°45'E, near the center o£ the western (Ralik) chain of the Marshall Islands (Figure 1). Composed of more than 90 islets, largely uninhabited, Kwajalein Atoll extends about 75 miles from southeast to northwest. It has a land area of about 6 square miles (3,854 acres) (Global Associates 1987), an increase of about 263 acres over the original area that was brought about by filling of land on Kwajalein, Roi-Namur, and Meek Islands.

Recent studies have shown that many coral reefs are capable of
yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala,
1981; Munro, 1987). There are, however, no estimates for the
productivity and yield of fishes associated with coral reefs in
French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

Island ecosystems have proven to be particularly sensitive to
human disturbances (Bourne 1975; Byrne 1980; Jarvis 1979). This was first noted by Charles Darwin in the explanation of his theory of natural selection (Byrne 1980). Since then, qualities of insular species have been examined by various authors in an attempt to understand the basis for island vulnerability.

During the period February 13 to 20, 1973, a visit was made to Canton Island for the purpose of conducting a preliminary survey of marine turtle nesting populations. Although previous investigators have described the sea birds (Buddle, 1938; Murphy G., 1954), insects (Van Zwaluwenburg, 1943, 1955), and vegetation (Hatheway, 1955), very little is known about the marine environment of Canton or the other seven atolls (Enderbury, Birnie, Phoenix, Sydney, Hull, Gardner and McKean) which comprise the Phoenix group.
Tuvalu, a small island nation in the Pacific, has in recent years lost about one metre of land around the circumference of its largest atoll due to changes in storm conditions and rising sea levels. Tuvalu is one of the worlds lowest lying countries, with its highest point standing a mere four and a half metres above sea level. Half of Tuvalus population of 11,000 people live just three metres above sea level

The Earth currently finds itself in the midst of what some have termed the "Anthropocene Era" - a period during which human activities have become a dominate force affecting not only the
planet's landscape, but also its atmosphere. Since the dawn of the industrial evolution of the mid-18th century, humans have contributed to substantial increases in the concentration of
greenhouse gases in the atmosphere. Carbon dioxide has increased by 36%, methane by 17%, and nitrous oxide by 151%. These changes in the global atmosphere are directly linked to over
