1. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

3. A literature review of the pollination strategies and breeding systems in Oncidiinae orchids
ABSTRACT Oncidiinae is an exclusively Neotropical orchid subtribe with about 1600 described species and an impressive array of vegetative and floral morphological adaptations. We present the results of a literature survey on the pollination strategies and breeding systems of this orchid subtribe. The flowers are pollinated by a wide range of insects (mostly

4. Bees biodiversity, forage behavior and fruit production in gherkin crop (Cucumis anguria L.)
ABSTRACT. The objectives were to evaluate the biodiversity of bees, forage behavior and their effect on fruit production in the gherkin crop (Cucumis anguria L.) in the campus of the University Center Moura Lacerda in two years. The frequency and type of collection of the insects in the flowers was observed by counting from 8:00 a.m. to 5:00 p.m., in the fir

5. Consumo de medicamentos por idosos atendidos em um centro de convivência no noroeste do Paraná, Brasil
Resumo O objetivo deste trabalho foi avaliar o consumo dos medicamentos, por idosos de um centro de convivência, relacionado aos aspectos de seu uso racional. Para isso foram realizadas visitas domiciliares, com entrevista baseada em um questionário estruturado. O resultado das 72 entrevistas mostrou que os idosos tinham baixa escolaridade, 66% pertenciam

6. Mulheres Indígenas nas Missões: patrimônio silenciado
Resumo: Ao problematizar o patrimônio histórico das Missões Indígenas-Jesuíticas (1609-1750) a partir de preocupações teórico-metodológicas relacionadas aos estudos de gênero e patrimônio, este artigo discute: a) representações sobre mulheres indígenas presentes na documentação histórica gerada pelos jesuítas; b) ressignificação dos espa�

7. Nectar ecology of the endemic epiphytic hummingbird-pollinated bromeliad Vriesea altodaserrae: secretion dynamics and pollinator visitation pattern
ABSTRACT Hummingbirds are the main pollinators of most bromeliad species, whose nectar traits usually respond to the selective pressures imposed by pollinators. Considering the specialization of hummingbird-pollinated bromeliads, we expect a close relationship between nectar ecophysiology and the needs of the main pollinators. In this sense, we studied the n

8. Breeding system and pollination of Pleroma trichopodum DC. (Melastomataceae): a potential species for the restoration of Atlantic Forest in southern Brazil
ABSTRACT Plant-pollinator interactions and their reproductive implications are of central importance to the organization of plant populations and communities in restoration areas. We studied the breeding system and flower visitors of Pleroma trichopodum, a pioneer species of the Atlantic Forest. We attempted to answer three questions: (1) Is P. trichopodum d

9. 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

10. Reproductive traits and floral visitors of Aechmea distichantha plants growing in different habitats of a South American xerophytic forest
Abstract Aechmea distichantha, a widely-distributed facultative epiphytic bromeliad species, is present from rainforests to xerophytic forests. At its southernmost distribution (Humid Chaco) it grows in the understory and forest edges. This animal-pollinated bromeliad shows high phenotypic plasticity on its vegetative traits, but there is no information abou

11. The rate of visitation by Amazilia fimbriata (Apodiformes: Trochilidae) influences seed production in Tillandsia stricta (Bromeliaceae)
Legitimate flowers visitors pollinate the flower during the visit and thus influence the production of fruits and seeds. We tested whether the visitation rate of potential pollinators is associated with the amount of seeds per fruit produced by the self-compatible bromeliad Tillandsia stricta (Bromeliaceae). We determined whether hummingbirds are legitimate

12. Use of bee-attractants in increasing crop productivity in Niger (Guizotia abyssinica. L)
The use of bee attractants, Bee-Q and Fruit BoostTM in the pollination of niger was evaluated. Bee visitations to niger flowers were observed for two weeks and an estimation of seed yield was determined. Different concentrations of Bee-Q and Fruit boostTM were evaluated to understand honeybee visitation patterns on the target crop and pollination efficiency.
