Pollination of Cambessedesia wurdackii in Brazilian Campo Rupestre Vegetation, with Special Reference to Crepuscular Bees
Abstract Cambessedesia wurdackii Martins (Myrtales: Melastomataceae) is presumably endemic to the Chapada Diamantina, Bahia State, Brazil. A majority of the species of this family are pollinated byExpand
Inter-annual variations in the abundance of young-of-the-year of migratory fishes in the Upper Paraná River floodplain: relations with hydrographic attributes.
In this study, we identified and characterized the hydrographic attributes related to the success of recruitment of migratory fishes in the Upper Paraná River floodplain. To achieve our objectives,Expand
POLLINATING BEES AND OTHER VISITORS OF LUDWIGIA ELEGANS (ONAGRACEAE) FLOWERS AT A TROPICAL SITE IN BRAZIL
Abstract Flowers of Ludwigia elegans present a set of generalized characteristics attracting visitors of several insect taxa, however, they strongly depend on bees for pollination. Bees of 32 speciesExpand
Daily activity patterns of visits by males of four species of Eulaema (Apidae: Euglossina) to odor baits in a tropical forest fragment in Bahia, Brasil
Several studies have been conducted with bees of the subtribe Euglossina using odor baits as attractants. The objective of this study was to analyze the daily activity pattern of visits by males ofExpand
Interactions between bees and Ludwigia elegans (Camb.) Hara (Onagraceae) flowers at different altitudes in São Paulo, Brazil
Populations of Ludwigia elegans (Carnb.) Hara were examined in Aluminio (600m) and Campos do Jordao (1520m), in the State of Sao Paulo. Flowers of both populations are self-incompatible and dependentExpand
[The pollination of Krameria bahiana B.B. Simpson by bees in the Coastal Sand Plains of Bahia, Brazil].
The flowers of K. bahiana mainly produce oil as floral resource for their visitors. Oil collecting bees usually show morphological and behavioral adaptation for their collection. This study focusedExpand
