TL;DR: In this paper, the authors present a comprehensive assessment of the conservation status and distribution of the world's mammals, including marine mammals, using data collected by 1700+ experts, covering all 5487 species.

TL;DR: Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.

TL;DR: The results provide the first analysis of the global conservation status and distribution patterns of reptiles and the threats affecting them, highlighting conservation priorities and knowledge gaps which need to be addressed urgently to ensure the continued survival of the world’s reptiles.

TL;DR: A comprehensive assessment of the conservation status and distribution of the world's mammals is presented, compiled by 1700+ experts, to suggest common mechanisms driving diversity and endemism across systems.

TL;DR: In this paper, the authors performed a comprehensive conservation status assessment focusing exclusively on the 45 species occurring in North America north of Mexico and found that 18-31% of the species were at risk (categorized as having vulnerable, imperiled, or critically imperiled NatureServe conservation statuses) and therefore among the most imperiled terrestrial vertebrates on the continent.
