-This study aimed at evaluating the effect of collect time (day and night) on ant fauna attracted to baits in areas of Eucalyptus cloeziana (Myrtaceae) and cerrado. The ants were collected in Fazenda Boa Vista, Mannesmann Fi -El Florestal Ltda, Paineiras, Minas Gerais State. Eigthteen sample units were collected: 12 in E. cloezina and six in cerrado. Each sample unit consisted of three plots (25 x 35 m each). The plot consisted of 34 baits distributed in a grid pattern at 5 m intervals. The sampling was carried out in the diurnal and nocturnal period. The results obtained revealed that both type of vegetation (cerrado x Eucalyptus) and the collect time (day x night) had a signifi cative infl uence on the epigaeic ant fauna. The ordination (DCA) indicated that collect time effect was more important to fauna structuration than the vegetation effect. (Finn et al. 1999). A variabilidade espacial tem sido levantada como um dos

A arborização urbana é um fator que vem sendo levado cada vez mais em conta no que diz respeito a pesquisas sobre a qualidade de vida nas cidades. Nesse sentido, vários trabalhos são realizados visando avaliar a arborização urbana em várias cidades brasileiras. O presente estudo teve por objetivo contribuir para a padronização desses trabalhos, fornecendo uma listagem e a caracterização das variáveis mais importantes utilizadas em pesquisas sobre arborização urbana, extraídas de diferentes publicações. O mesmo contribuirá ainda de forma significativa para a realização de pesquisas com o referido tema

Formicivora grisea (Boddaert, 1783) (Aves: Thamnophilidae), popularly known as white–fringed antwren, is a common species in Brazil, occurring from the Amazon to eastern part of this country, living in the edges of wet and dry forests, secondary forest, capoeira and Restinga Forest, Caatinga Forest and secondary forest. This study presents a documented record and ringing of two individuals of this species on the coast of Piauí. The specimens, a female and a male, were captured with mist nets during sampling effort on a Restinga area with elements of Cerrado and Caatinga the aim of the avifauna characterization and inventory on the ecosystem situated near the International Airport of Parnaíba, Piauí, on 12/IX/2010..
