38. Pollen morphology of Brazilian species of Verbesina L. (Heliantheae - Asteraceae)
Abstract There are nine species of the plant genus Verbesina in Brazil, which are distributed in the Northeast, Center-West, Southeast and South regions of the country. The objective of the present study was to describe the pollinic morphology of eight of these species to better characterize them and evaluate potential species-level taxonomic characters. Ace

40. A new species of Asphondylia (Diptera: Cecidomyiidae) and a key to separate species of the genus associated with Asteraceae from Neotropical region
Abstract A new species, Asphondylia cipo sp. nov. (Diptera: Cecidomyiidae) causing stem and petiole galls on Lessingianthus warmingianus (Baker) H. Rob. (Asteraceae) is described and illustrated from Serra do Cipó, Minas Gerais State, Brazil. A key is provided to separate species of this genus associated with host plants in the Asteraceae family from the Ne

42. A study of the phytotoxic effects of the aerial parts of Senecio westermanii Dusén (Asteraceae) on Lactuca sativa L. and Allium cepa L. seeds
The objective of this study was to evaluate the effects of the ethanolic crude extracts and fractions of the species Senecio westermanii Dusén on Lactuca sativa L. (lettuce) and Allium cepa L. (onion) seeds. We assessed the germination, growth, root respiration and photosynthesis of the target species in Petri dishes (9.0 cm diameter) containing filter pape

45. Fruit of Lepidaploa (Cass.) Cass. (Vernonieae, Asteraceae): anatomy and taxonomic implications
ABSTRACT Lepidaploa is a taxonomically complex genus of Vernonieae, which is difficult to delimit morphologically due to vegetative and reproductive characters that overlap with Chrysolaena and Lessingianthus. Anatomical studies of cypselae are taxonomically useful for delimiting subtribes, genera and species of Asteraceae, and especially within Astereae and

46. Are native bees and Apis mellifera equally efficient pollinators of the rupestrian grassland daisy Aspilia jolyana (Asteraceae)?
ABSTRACT Most angiosperms rely on animals for pollination, and insects, especially bees, are being the most frequent pollinators. Many native Neotropical plants are frequently visited by the invasive honeybee (Apis mellifera), but its role in the pollination of these plants has been little investigated. We assessed the contribution of various floral visitors

47. Together yet separate: variation in soil chemistry determines differences in the arboreal-shrub structure of two contiguous rupestrian environments
ABSTRACT Rupestrian landscapes are characterized by vegetation mosaics comprised of different plant communities and strongly linked to environmental filters. These environments are nutrient-impoverished, and possess water retention deficits and high solar exposure. This study aimed to determine whether chemical properties of the soil shape the arboreal-shrub

48. Insetos indutores de galhas das florestas decidual e semidecidual no Estado do Rio Grande do Sul, Brasil
RESUMO Galhas são alterações específicas induzidas por insetos sobre órgãos das plantas principalmente através de aumento no número e/ou tamanho das células vegetais. A diversidade de galhas é reconhecível em campo porque os galhadores são na sua vasta maioria espécie-específicos e assim cada morfotipo de galha serve como proxy para uma espéci
