Produção de serapilheira como bioindicador de recuperação em plantio adensado de revegetação
Litter deposition pattern was applied as bioindicator to compare sites at different successional stages with a dense restoration plantation. Litter traps (0.25 m2) were used and a production of 10.17 Mg ha-1 year-1 was obtained for secondary forest similar to a medium sector in the restoration area (8.98 Mg ha-1 year-1). Lower (5.85 Mg ha-1 year-1), upper (5.81 Mg ha-1 year -1), and bush (5.63 Mg ha-1 year-1) land production were similar to litter deposition values obtained from disturbed forests. Despite the need of more comparative parameters, litter deposition can be applied as restoration bioindicator
The exotic wasp Megastigmus transvaalensis (Hymenoptera: Torymidae): first record and damage on the Brazilian peppertree, Schinus terebinthifolius drupes, in São Paulo, Brazil
ABSTRACT This paper records the first report of Megastigmus transvaalensis Hussey (Hymenoptera: Torymidae) in Brazilian peppertree, Schinus terebinthifolius Raddi (Anacardiaceae) drupes in Sorocaba, state of São Paulo, Brazil. This wasp is an invasive species and was found damaging S. terebinthifolius drupes in urban areas (35.0±15.8%), natural forests (21.5±10.2%) and restoration areas (15.8±8.4%). The bio-ecology and damage caused by M. transvaalensis in the S. terebinthifolius drupes warrants further study focused upon the management of this phytophagous wasp. Megastigmus transvaalensis has a potential to be disseminated throughout Brazil and is posing a threat to the natural regeneration of S. terebinthifolius in the native forests and restoration areas and ecological regions of this country
