說明
Bats have been surveyed in 39 sites, comprising continuous forest (CF), fragments, forest edges and intervening secondary regrowth. For each site, the authors assessed vegetation structure (local-scale variable) and, for five focal scales, quantified habitat amount and four landscape configuration metrics. Each sampling site was visited eight times over a 2-year period, between August 2011 and June 2013. Bats were captured using 14 ground-level mist nets (12 9 2.5 m, 16 mm mesh, ECOTONE, Poland) in CF and fragment interiors, and seven ground-level mist nets at the edge and matrix sites. Mist nets were deployed along existing trails which are known to be used by Neotropical bats as commuting flyways. At edge sites, these trails ran parallel to the border between primary forest and secondary regrowth. In the study area mist netting efficiency was found to be highest in the first few hours after sunset. Sampling therefore started at dusk and was performed for 6 h during which nets were visited at intervals of ~20 min. Mist netting at the same location for consecutive days can lead to diminishing capture efficiency over time. Such net-shyness related bias was avoided by spacing visits to the same site 3-4 weeks apart. Species were identified following Gardner (2007) and Lim and Engstrom (2010), and taxonomy follows Gardner (2007). Most adult bats were marked with individually numbered ball-chain necklaces (frugivores and Pteronotus parnellii) or subcutaneous transponders (gleaning animalivores).

取樣方法
For each site, vegetation structure and bat assemblages were sampled. Bats were captured using 14 ground-level mist nets (12 9 2.5 m, 16 mm mesh, ECOTONE, Poland) in CF and fragment interiors, and seven ground-level mist nets at the edge and matrix sites. Mist nets were deployed along existing trails which are known to be used by Neotropical bats as commuting flyways (Palmeirim and Etheridge 1985). At edge sites, these trails ran parallel to the border between primary forest and secondary regrowth. Sampling started at dusk and was performed for 6 h during which nets were visited at intervals of*20 min. Visits were spaced 3-4 weeks apart. Species were identified following Gardner (2007) and Lim and Engstrom (2010), and taxonomy follows Gardner (2007). Most adult bats were marked with individually numbered ball-chain necklaces (frugivores and Pteronotus parnellii) or subcutaneous transponders (gleaning animalivores).
