| long-term dynamics of a fragmented rainforest mammal assemblage. | habitat fragmentation is a severe threat to tropical biotas, but its long-term effects are poorly understood. we evaluated longer-term changes in the abundance of larger (>1 kg) mammals in fragmented and intact rainforest and in riparian "corridors" in tropical queensland, with data from 190 spotlighting surveys conducted in 1986-1987 and 2006-2007. in 1986-1987 when most fragments were already 20-50 years old, mammal assemblages differed markedly between fragmented and intact forest. most vulne ... | 2008 | 18637907 |
