As the most threatened vertebrate class on earth, amphibians are at the forefront of the biodiversity crisis, with the recognition of global amphibian declines and extinctions dating back several decades now.

China’s Yangtze river dolphin (Lipotes vexillifer), was declared likely to be extinct in 2006, due to threats in the wild such as habitat loss, entanglement in fishing gear and ship strikes, which were not effectively dealt with using the management tools available prior to that time. Mexico’s vaquita (Phocoena sinus), a porpoise found only in the Upper Gulf of California, will become extinct in the near future if the illegal fishery to obtain fish swim bladders for illicit international markets is not eliminated very soon.

La predicción de los impactos del cambio climático sobre la biodiversidad es un gran desafío científico. Se han desarrollado diferentes métodos para la evaluación de la vulnerabilidad al cambio climático (EVCC) de las especies y se está produciendo una gran y creciente cantarget_idad de literatura científica al respecto. Nuestra motivación para realizar este documento es disminuir la magnitud del desafío que enfrentan los conservacionistas al interpretar y utilizar la compleja y frecuentemente inconsistente literatura sobre EVCC.

Tujuan utama panduan ini adalah untuk membantu mereka yang aktif terlibat dalam penangkapan ular dan situasi perdagangan, yang dihadapi dengan keperluan untuk melaksanakan pemantauan dan pengurusan. Panduan ini ditulis untuk pengurus hidupan liar kerajaan, pemulih konservasi, saintis profesional, dan amatur yang berminat untuk memastikan penggunaan ular ternakan liar dalam perdagangan komersial adalah kekal.

Tujuan utama buku panduan ini untuk membantu mereka yang berkecimpung dalam perdagangan dan panenan ular yang dihadapkan pada perlunya menerapkan monitoring dan manajemen. Buku panduan ini dibuat untuk pengelola satwa liar pemerintah, ahli konservasi, ilmuwan amatir dan profesional yang tertarik untuk memanfaatkan perdagangan komersial ular tangkapan secara lestari. Buku panduan untuk monitoring hasil panen ini dapat diterapkan apabila menerapkan strategi monitoring lainnya target_idak layak untuk dilakukan.

The primary purpose of these guidelines is to assist those actively engaged in snake harvest and trade situations, who are faced with the need to implement monitoring and management. It is written for government wildlife managers, conservationists, professional scientists, and amateurs interested in ensuring the sustainable utilization of wildcaught snakes in commercial trade. This guidance for harvest monitoring may be particularly applicable in situations where implementing other monitoring strategies is not feasible.

The papers in this volume were, with a few exceptions, presented at the third Island Invasives conference, held in Dundee, Scotland in July 2017.  The papers demonstrate up-scaling in several aspects of eradication operations – not least in ambition, land area, operational size, global reach and of course financial cost. In the space of a few decades, the size of islands treated for invasive species has increased by five orders of magnitude – from a few hectares to over 100,000 ha or 1,000 km2.

The material within these proceedings represents a summary for 2009–2016 on the state of knowledge and conservation concerns for polar bears throughout their range. The difficulties in studying a species that ranges widely, at low densities, and in one of the world’s most remote and environmentally challenging regions is evident in these proceedings. This report describes the current and future challenges and the conservation efforts needed to ensure the survival of polar bears.

The Mediterranean Basin biodiversity hotspot is known to be one of the most biologically rich and complex regions on Earth. The north-western part of the hotspot (the area that covers all of the Iberian Peninsula, southern France, most of Italy and Malta) supports important river, lake, karst and wetland systems critical for the survival of threatened and restricted range freshwater species.
