Identifying hotspots of biological diversity is a key step in a conservation prioritisation. Melanesia centred on the vast island of New Guinea - is increasingly for its exceptionally species rich and endemic biota. Here we show that Melanesia has the world's most diverse insular amphibian fauna, with over 7% of recognised global fog species in less than 0.7% of the world's land area and over 97% of species endemic.

The yellow-legged hornet (Vespa velutina) was detected for the ?rst time in the north of Spain in 2010, but was not detected in Majorca, Balearic Islands until 2015 and only one secondary nest, with 10 combs, was found in the northwest of the island. During 2016, nine more nests were found in the same region. To better understand the biology of V. velutina in isolated conditions, the following objectives were proposed: (I) describe the architecture and structure of nests; (II) analyse the shape of combs and develop a new method to con?rm the circular pattern of breeding; (III) determine the colony size and (IV) determine the succession of workers and sexual individuals throughout the season. For these reasons, nests that were removed were frozen for at least 48 days until analysis. Our results show that this species has a high reproductive potential under isolated conditions. Results reveal that parameters such as weight, height, diameter, number of cells and total individual production are directly related. Moreover, each mature nest can produce up to 9,000 individuals and several hundred potential founder queens. All results inform formulation of an e?cient control or eradication programme in the Balearic Islands, as we are in the early stages of invasion and intervention is essential to eradicate V. velutina on Majorca Island.

This report provides an overview of the current state of knowledge of cetacean diversity, habitat and threats in the Pacifi c Islands Region. The boundaries of the Pacifi c Islands Region (Chapter 1), as defi ned by the Convention of Migratory Species (CMS) Memorandum of Understanding (MoU) for the Conservation of Cetaceans and their Habitats in the Pacifi c Islands Region (CMS 2006), are the marine areas under the jurisdiction of each Country or Territory of the Pacifi c Islands Region, and extend to the area defi ned by the Noumea Convention, i.e., between the Tropic of Cancer and 60° South latitude, and between 130° East longitude and 120° West longitude. The region stretches over some 10,000 kilometres from east to west and 5,000 kilometres from north to south, with a combined economic exclusion zone (EEZ) of approximately 30 million km². This region contains 22 Pacifi c Island Countries and Territories, as well as a portion of the Australian continent, both the North and South Islands of New Zealand, and a portion of the Hawaiian Islands. The region is purported to hold the most extensive and biologically diverse reefs in the world, the deepest ocean trenches, the world’s largest tuna fi shery, as well as a range of globally threatened species such as sea turtles, dugongs and cetaceans (UNDP 1999)
