Profile of pediatric eye trauma at Hospital de Base do Distrito Federal (HBDF), Brasília, Brazil.

Objective: To describe the epidemiological profile of ocular trauma in children at the HBDF emergency department.

Method: Descriptive, cross-sectional study. We evaluated 103 cases of ocular trauma in children less than 15 years between July 2012 and January 2013.

Potential effects of climate change on canopy communities in a tropical cloud forest: an experimental approach.

Global climate change models predict reduced cloud water in tropical montane forests. To test the effects of reduced cloud water on epiphytes, plants that are tightly coupled to atmospheric inputs, we transplanted epiphytes and their arboreal soil from upper cloud forest trees to trees at slightly lower elevations that are naturally exposed to less cloud water. Control plants moved between trees within the upper site showed no transplantation effects, but experimental plants at lower sites had significantly higher leaf mortality, lower leaf production, and reduced longevity.
