Many studies of extinction thresholds associated with habitat reduction have focused on animals, generally at the patch scale. However, certain plant groups are very interesting models with which to study this type of relationship, such as Myrtaceae in Neotropical forests. Because trees are long-lived organisms, local extinctions in response to habitat loss may occur in different ways due to a time lag. In this study, our objective was to assess the occurrence of extinction thresholds at the landscape scale for Myrtaceae in a large biome and the pattern of species reduction in different tree size classes. We studied nine landscapes with different amounts of available habitat (between 5 and 55 % forest cover) in different parts of the Atlantic Forest in Bahia, Brazil, and in each landscape, we evaluated four plant classes based on tree circumference: saplings (CBH between 8 and 15 cm), young (CBH between 15 and 30 cm) adults (CBH ≥30 cm) and total (all individuals with CBH ≥8 cm). Landscapes with forest cover less than 25 % presented an approximately sixfold reduction in Myrtaceae total species richness compared with landscapes with forest cover greater than 40 %. We identified a relationship with a threshold between the amount of available habitat at the landscape level and Myrtaceae richness, with a reduction in total, sapling and young species below a threshold of 40 % forest cover, whereas adults had an extinction threshold at 30 % forest cover. We discuss the differences among the categories of plants associated with a time lag and the possibilities and limitations in applying these results in environmental management.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-03-25T11:02:05Z No. of bitstreams: 1 art%3A10.1007%2Fs10531-013-0575-4.pdf: 503281 bytes, checksum: 703cfd8a28e311e2b5cf25e6a775504a (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-09-09T16:00:37Z (GMT) No. of bitstreams: 1 art%3A10.1007%2Fs10531-013-0575-4.pdf: 503281 bytes, checksum: 703cfd8a28e311e2b5cf25e6a775504a (MD5)Made available in DSpace on 2014-09-09T16:00:37Z (GMT).
