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.

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.

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.
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.
