Protected areas (PAs) are a cornerstone of conservation efforts and now cover nearly 13% of the world's land surface, with the world's governments committed to expand this to 17%. However, as biodiversity continues to decline, the effectiveness of PAs in reducing the extinction risk of species remains largely untested. We analyzed PA coverage and trends in(More)
Conservation actions, such as habitat protection, attempt to halt the loss of threatened species and help their populations recover. The efficiency and the effectiveness of actions have been examined individually. However, conservation actions generally occur simultaneously, so the full suite of implemented conservation actions should be assessed. We used(More)
Abundances from our non–LTE analyses compared to predictions from diffusion calculations (Chayer et al. 1995, Chayer priv. comm.) Element abundances are given as logarithmic number ratios relative to helium. Uncertain results are marked by a colon. below 1 at the beginning of the cooling track towards 5 at the hot edge of the DB gap (going to infinity(More)
