1. Pollination biology of the endangered columnar cactus Cipocereus crassisepalus: a case of close relationship between plant and pollinator
ABSTRACT The family Cactaceae possesses considerable floral diversity and is exclusively zoophilic. Cipocereus crassisepalus is an endangered species of columnar cactus, whose floral characteristics fit the chiropterophily syndrome. This study aimed to assess the correspondence between floral traits and pollinators and whether the pollination system of C. cr

2. Sexual Systems of Plants in a Brazilian Montane Forest
ABSTRACT In this study, vegetation reproduction has been investigated in order to understand aspects of speciation, structuring and composition of plant communities. Thus, we sought to characterize the frequency of sexual systems from species recorded in seed rain occurring in a tropical rainforest (Atlantic Forest) in Caparaó National Park, Espírito Santo

3. Genetic diversity and population structure of naturally rare Calibrachoa species with small distribution in southern Brazil
Abstract Calibrachoa is a South-American genus comprising 27 species, several considered endemic or rare; few were subjects in genetic studies. We attempted to generate new data about the phylogenetically related and rare species C. eglandulata, C. sendtneriana, C. serrulata, and C. spathulata concerning their genetic diversity and population structure, whic

4. Reproductive Biology of Varronia curassavica Jacq. (Boraginaceae)
ABSTRACT Varronia curassavica, a subshrubby medicinal species associated with restinga in the Atlantic Forest, has been exploited by local people and the pharmaceutical industry. Indeed, restingas have experienced a continuous process of degradation, and thus, with species and ecosystem both at risk, efforts to support conservation actions are required. The

5. Phenodynamics of five orchids species growing on rock outcrops in the Chapada Diamantina Mountains in northeastern Brazil
ABSTRACT We evaluated the vegetative and reproductive phenological patterns of the orchids Cattleya elongata, Cyrtopodium aliciae, Epidendrum orchidiflorum, Epistephium lucidum, and Sobralia liliastrum (Orchidaceae) growing on sandstone outcrops in the Chapada Diamantina Mountains in northeastern Brazil. Phenological events were associated with abiotic facto

6. Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities. We compiled data on pollination and dispersal syndromes of 406 plant species distributed among different elevations in Área de Proteção Ambiental da Serra de Baturité (

7. Abelhas visitantes florais e potenciais polinizadores da cajazeira (Spondias mombin L.) sob cultivo, na Chapada do Apodi, Cearà / Bee and flower visitors from potential pollinators mombin (Spondias Mombin L.) under cultivation in Apodi Plateau, State of CearÃ
The research was carried out from November of 2009 to January of 2010, in the Apodi plateau, situated in the county of Limoeiro do Norte, state of CearÃ. It was used 32 cajazeira trees (Spondias mombim L.) of the Lagoa Redonda cloning tree, grafted on the umbuzeiro tree (Spondias tuberose A.). The objective was to verify some variables regarding to floral b

8. Ecologia da polinizaÃÃo e biologia reprodutiva de Ipomoea bahiensis Willd. no semi-Ãrido brasileiro / Pollination ecology and reproductive biology of Ipomoea bahiensis Willd. in semi-arid
O estudo da ecologia floral à fundamental para o entendimento das relaÃÃes entre flores e seus visitantes, assim como para entender o papel dessa interaÃÃo no sucesso reprodutivo e na manutenÃÃo da populaÃÃo vegetal. No presente estudo, investigou-se a morfologia, a biologia floral e o sistema de reproduÃÃo de Ipomoea bahiensis Willd., bem como as

9. Pollination of Adenocalymma bracteatum (Bignoniaceae): floral biology and visitors
Adenocalymma bracteatum is a shrub of dense foliage and yellow flowers, easily found on grasslands areas in Central Brazil. The aim of this study was to determine the reproductive biology and the flower visitors of A. bracteatum in a pasture area nearby Ivinhema city, MS (Brazil). The flowering peak occurs in winter. The flower reflects ultraviolet light. An

10. Biologia reprodutiva de Guettarda platypoda DC. (Rubiaceae) em uma área de restinga no Estado de Pernambuco
Distyly is a syndrome mainly found in the Rubiaceae family, being characterized by a floral dimorphism in which some individuals have thrum flowers (T) and others have pin ones (P). Typical distylous species present reciprocal hercogamy between floral morphs, a self and intramorph incompatibility mechanism and an equilibrated proportion of morphs in the popu

11. Diversidade genética e fluxo gênico via pólen e semente em populações de Solanum lycocarpum ST.HIL. (Solanaceae) no sudeste de Goiás / Genetic diversity and gene flow by pollen and seed in populations of Solanum Lycocarpum St.Hil. (Solanaceae) in the southeast of the state of Goiás
Solanum lycocarpum St.Hil. (Solanaceae) is a woody plant that is found in the Brazilian Cerrados (savanna fields) in Central Brazil. It is heliophile, and it features open secondary formations. Its popularly known as wolfs fruit. The meat of its fruit is used in the production of a phytomedicine, the wolfs fruit powder, which is traded in the form of capsule

12. Polinização e dispersão de sementes em solanaceas neotropicais
To understand the ecological processes that provides the functioning of an ecosystem implies in conducting multiple studies about its components and interactions. In this sense, it is very important to know the functional relationships of the species and to make comparisons (both intercommunity and pancommunity) among groups of species phylogenetically relat
