Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of the world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine mammals. Global macroecological patterns are very different for land and(More)
Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to(More)
This paper presents a new algorithm for the generation of pipelined designs developed for use in an interactive behavioural synthesis system. Our technique uses a novel iterative optimisation algorithm that allows the user to trade-off interactive response time with solution quality. Two examples are given to demonstrate the effectiveness of our approach.(More)
Previous studies show that conservation actions have prevented extinctions, recovered populations, and reduced declining trends in global biodiversity. However, all studies to date have substantially underestimated the difference conservation action makes because they failed to account fully for what would have happened in the absence thereof. We undertook(More)
A survey of fecal samples found enterococcal excretion in 82% of 388 bank voles (Clethrionomys glareolus), 92% of 131 woodmice (Apodemus sylvaticus), and 75% of 165 badgers (Meles meles). Vancomycin-resistant enterococci, all Enterococcus faecium of vanA genotype, were excreted by 4.6% of the woodmice and 1.2% of the badgers, but by none of the bank voles.
The historical distribution of the cheetah Acinonyx jubatus extended from Africa through the Arabian Peninsula into Iran and Afghanistan. From there, the range continued eastwards to Pakistan and India, and northeast through Central Asia: Uzbekistan, Kazakhstan and Turkmenistan (Nowell & Jackson 1996). During the Middle Ages, cheetahs also occurred to the(More)
