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 North American signal cray?sh (Pacifastacus leniusculus) has been present in Scotland since at least 1995 and the species is now known to be present in a number of catchments. Once established, few opportunities for containment exist and eradication can often be impossible to achieve. However, in small, isolated water bodies, the application of a non-cray?sh-speci?c biocide has provided the opportunity to remove this species permanently. In July 2011, signal cray?sh were discovered in a ?ooded quarry pond at Ballachulish in the Scottish Highlands. This is an isolated site located ~100 km from the nearest known population and it is likely that the population was established as the result of a deliberate release of these animals 10 years previously. Experience gained from using the eradication technique at other sites in the UK led to the site being treated with a natural pyrethrum biocide (Pyblast®) in June 2012. Post treatment monitoring from 2012–2017 indicates that eradication has been successful. Monitoring of native species a?ected by the biocide suggests that both invertebrates and amphibians quickly recolonised the quarry pond. Eradication of cray?sh using biocide is only feasible in water bodies where the entire population of cray?sh can be exposed to a lethal dose and the impact on non-target species can be accepted. The technique is not appropriate for large, connected water bodies, although it may be possible to treat short stretches of canals where biocide exposure can be controlled and isolated populations of cray?sh can be e?ectively treated.
Eradication of invasive alien crayfish: past experiences and further possibilities

The EU regulation 1143/2014 “On the prevention and management of the introduction and spread of invasive alien species” entered into force on 1 January 2015. On 13 July 2016, the EU list of invasive alien species that require action was adopted. The list includes ?ve di?erent cray?sh species. Member states will be required to take measures for early detection and rapid eradication of these species. Except for some eradications performed in the United Kingdom and Norway, there has not been much e?ort put into eradication of invasive cray?sh species throughout Europe. The reasons for this are probably complex and di?er between member states. Are the main reasons legislative constraints, ability to eradicate or lack of knowledge and experience? Is eradication of alien cray?sh possible and desirable, and what is left to save in Europe? Focus could be put into identifying or creating island populations of special concern and preserve them for the future survival of European native cray?sh populations. Eradication measures should be considered as an option in this work. What are the experiences from completed eradication e?orts in Europe? Two cray?sh eradications have been performed in Norway, and both have been successful. The eradications were performed in locations with several ponds and small streams and performed using the synthetic pyrethroid-based pharmaceutical BETAMAX VET®. Both legislative and funding constraints seem less prominent as successful eradications have been con?rmed. Time will show if this trend will spread throughout Europe.
Current state of knowledge of Cetacean Threats, Diversity and Habitats in the Pacific Islands Region / by Cara Miller

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)
