FUNGOS CONIDIAIS ASSOCIADOS A FOLHAS EM DECOMPOSIÇÃO DE Clusia melchiori Gleason e C. nemorosa G. Mey EM FRAGMENTO DE MATA ATLÂNTICA, BAHIA, BRASIL

Os fungos conidiais constituem um grupo diversificado, com cerca de 15.945 espécies. Contudo, pesquisas taxonômicas sobre esses fungos no Brasil permanecem escassas e pontuais abordando, sobretudo, os decompositores de substratos vegetais. A Serra da Jibóia, fragmento de Mata Atlântica inserido na Caatinga do Estado da Bahia, foi selecionada como prioritária para conservação da biodiversidade. Visando contribuir para o conhecimento dos fungos conidiais na área, folhas em decomposição de três indivíduos de Clusia nemorosa, e C. melchiori foram coletadas bimestralmente de outubro/2005 a junho/2006. No laboratório, as folhas foram lavadas, colocadas em câmara-úmida e os fungos identific...

Yellow-bellied Elaenia ( Elaenia flavogaster )

16cm Identification: the genus Elaenia is well known among the ornithologists for being one of the most difficult groups when it comes to species identification. Nevertheless Elaenia flavogaster is the easiest species to be identified, first for its yellow belly, second for the crest on the head (not always visible), third for the absence of white patches on the face and crest and last for its conspicuous behavior. It is more easily heard than seen and its song reminds the one of the kiskadee. It inhabits parks, backyards, coffee crops and secondary forest edges. The yellow bellied elaenia spends most of its time in the medium height trees and shrubs. Feeds mainly on insects and be...
