Four surveys of Phytoseiidae species associated with native plants were conducted in ten fragments of Cerrado sensu stricto to determine the species associated with the plants of this region. Twelve of the most common plant ...
Phytochemical evidence for the plant origin of Brazilian propolis from Sao Paulo state
(1999-05-01)
Propolis and plant secretions from three species, most frequently mentioned as botanical sources of the bee glue in Brazil (Baccharis dracunculifolia, Araucaria angustifolia and Eucalyptus citriodora) have been investigated ...
Colonization pattern of Cecropia by Azteca ants: Influence of plant ontogeny, environment and host plant choice by queens
(California State University, 2008-01-01)
Several plant species of the large Neotropical genus Cecropia acts as a host plant for ants, especially those of the genus Azteca. Although literature has reported that the Azteca queens found colonies by perforating the ...
Seed rain and seed limitation in a planted gallery forest in Brazil
(Blackwell Publishing, 2006-12-01)
With seeds collected monthly during one year from 53 1-m(2) seed traps, we investigated the seed rain and seed limitation in a gallery forest planted in 1994 in SE Brazil. Contrasting animal- (zoochorous) and wind-dispersed ...
Morphological patterns of extrafloral nectaries in woody plant species of the Brazilian cerrado
(Wiley-Blackwell, 2008-09-01)
Extrafloral nectaries are nectar-secreting structures that are especially common among the woody flora of the Brazilian cerrado, a savanna-like vegetation. In this study, we provide morphological and anatomical descriptions ...

Plants of different species were inoculated with a Curtobacterium flaccumfaciens pv. flaccumfaciens isolate by spray and stem puncturing. Common bean (Phaseolus vulgaris L.) plants inoculated with bacterial suspension in ...
Phenological visual rhythms: Compact representations for fine-grained plant species identification
(Elsevier Science Bv, 2016)
Plant phenology, the study of recurrent life cycles events and its relationship to climate, is a key discipline in climate change research. In this context, digital cameras have been effectively used to monitor leaf flushing ...
Profile of Maytenus aquifolium action over free radicals and reactive oxygen species
(2007-07-01)
Reactive oxygen species (ROS) and free radical species have been implicated in initiating, accompanying or causing many diseases in living organisms; there is thus, a continual need for antioxidants molecules to inactivate ...
