The Extinct Sloth Lemurs of Madagascar

The sloth lemurs, or Palaeopropithecidae, comprise four of the eight recognized genera of extinct lemurs and more than a third of the extinct species (Table 1; Figs. 1 and 2). Four genera are currently recognized as belonging in this family: Palaeopropithecus (the type genus), the truly gigantic Archaeoindris, the much smaller-bodied Mesopropithecus, and the midsized, recently discovered Babako...

Reconstruction of an extraordinary extinct primate from Madagascar.

T he minicontinent of Madagascar has been separated by 350 miles of ocean from its neighbor Africa for at least the past 120 million years, i.e., since long before the beginning of the Age of Mammals (1). As a result, the island’s f lora and fauna show extremely elevated levels of endemicity overall (2), and its native mammals show a curious combination of low diversity at the ordinal level wit...

Rheumatoid vasculitis: becoming extinct?

BACKGROUND Systemic rheumatoid vasculitis (SRV) is a relatively rare complication of RA. The incidence of SRV appeared to increase during the 1970s and 1980s from 6.0 to 12.5/million. During the 1990s there have been major changes in the treatment of RA, with more aggressive control of inflammation. Our aim was to study the epidemiology of SRV in a stable, well-defined population over a 15-yr p...
