Drivers of Extinction Risk in Terrestrial Vertebrates rating of “vulnerability to extinction” for that species Research effort can affect the number of threats associ-ated with a given species in IUCN listings (more inten-sively studied mammal species are rated as being sub-ject to more threats: Gonzalez-Suarez et al 2012) We thus included an index of research effort in our anal-yses
Red-list status and extinction risk of the world’s whales . . . One in 4 cetacean species (26% of 92 species) was threatened with extinction (i e , criti-cally endangered, endangered, or vulnerable) and 11% were near threatened Ten percent of cetacean species were data deficient, and we predicted that 2–3 of these species may also be threatened The proportion of threatened cetaceans has increased: 15%
EDGE Mammals - EDGE of Existence Numbers represent the number of species impacted by each threat Data from IUCN Red List Alarmingly, over 20% of mammals are threatened with extinction and more than 50% of EDGE mammals are currently receiving little or no conservation attention Many of the most poorly-known species are in danger of slipping towards extinction unnoticed
Threatened bird species are concentrated in regions with less . . . Threatened birds (310 species) were further divided into two groups, i e , endangered birds (critically endangered, endangered, and vulnerable; 134 species) and near threatened (176 species) The proportion of all threatened birds, endangered birds, and near threatened birds was calculated as the richness of each of these three threatened
Science for Saving Species listed as impacting listed threatened species: 207 plants, 57 animals and three pathogens This includes 230 non-native species (187 plants, 41 animals and two pathogens) and 37 problematic native species (20 animals, 16 plants and one pathogen) Of all invasive species, rabbits top the list for impacting the most threatened species, 322 in total,
The impacts of extreme climate change on mammals differ among . . . 1 INTRODUCTION Climate is predicted to drive marked increase in temperature and pronounced changes in precipitation patterns worldwide (IPCC, 2018) Although species may be able to survive in situ or adapt to the new conditions (Vaughan et al , 2015), these changes are expected to greatly impact the distribution patterns of many species globally (Thomas et al , 2006; Lenoir and Svenning, 2015)
Quarter of UK’s mammals at risk of extinction It reveals 11 of the 47 mammals native to Britain are on the brink of extinction, while a further five species are classified as “near threatened” Among those species listed as being at risk
