6-Oxygenated flavones from Baccharis trinervis (Asteraceae).
Baccharis trinervis (Lam.) Pers. (Family: Asteraceae alt. Compositae), used in South American folk medicine as an antiseptic, digestive and to treat snake-bites (Duke, 1999), is widely distributed from Mexico to Argentina (USDA-ARS-GRIN database, 1999). Plant material was collected from Costa Rica and supplied by Biotics Limited, University of Sussex, Brighton, UK. A voucher specimen (MNL10118)...
متن کاملInsect herbivores associated with Baccharis dracunculifolia (Asteraceae): responses of gall-forming and free-feeding insects to latitudinal variation.
The spatial heterogeneity hypothesis has been invoked to explain the increase in species diversity from the poles to the tropics: the tropics may be more diverse because they contain more habitats and micro-habitats. In this paper, the spatial heterogeneity hypothesis prediction was tested by evaluating the variation in richness of two guilds of insect herbivores (gall-formers and free-feeders)...

متن کاملCharacterization of microsatellite markers for Baccharis dracunculifolia (Asteraceae).
PREMISE OF THE STUDY Baccharis dracunculifolia (Asteraceae) is a native plant of the Atlantic Forest that is used for the production of essential oil. Microsatellite markers were developed for this species to investigate the genetic diversity of three natural populations. METHODS AND RESULTS Seventeen out of 27 microsatellite loci identified in a genomic library used for the characterization ...
متن کاملPlant Phenology and Absence of Sex-Biased Gall Attack on Three Species of Baccharis
BACKGROUND Dioecy represents a source of variation in plant quality to herbivores due to sexual differences in intensity and timing of resource allocation to growth, defense and reproduction. Male plants have higher growth rates and should be more susceptible to herbivores than females, due to a lower investment in defense and reproduction. METHODOLOGY/PRINCIPAL FINDINGS We compared resource ...
