Comportamento fenológico de três espécies de Jatropha (Euphorbiaceae) da Caatinga, semi-árido do Brasil
Provedor de dados: 88
Autores: Neves,Edinaldo Luz das; Funch,Ligia Silveira; Viana,Blandina Felipe.
O comportamento fenológico vegetativo e reprodutivo de Jatropha mollissima (Pohl) Baill., Jatropha mutabilis (Pohl) Baill. e Jatropha ribifolia (Pohl) Baill. foi comparado em uma área de caatinga hiperxerófila arbustiva-arbórea do nordeste brasileiro, no período de julho de 2005 a junho de 2007. Adicionalmente, investigou-se a correlação entre as fenofases e as variáveis abióticas (temperatura, umidade relativa, precipitação e fotoperíodo), a capacidade de armazenamento de água e o padrão de distribuição espacial. Todas as espécies apresentaram alta capacidade de armazenamento de água e comportamento fenológico contínuo e irregular com ausência de flores, frutos, queda foliar e brotamento nos meses mais frios e úmidos do ano. Apenas a floração de J....

Autores: Neves,Edinaldo Luz das; Machado,Isabel Cristina; Viana,Blandina Felipe.
São apresentados a biologia floral, a dinâmica de produção de néctar, visitantes florais e sistemas reprodutivos de Jatropha ribifolia (Pohl) Baill. (Euphorbiaceae) e uma comparação dos dados obtidos para J. mollissima (Pohl) Baill. e J. mutabilis (Pohl) Baill. O estudo foi desenvolvido em uma área de caatinga hiperxerófila, na Estação Biológica de Canudos, Bahia, Brasil, de maio de 2005 a junho de 2007. As flores das três espécies estão organizadas em dicásios protogínicos. Em J. ribifolia as flores estaminadas e pistiladas duram cerca de 48 horas e a abertura é diurna, enquanto em J. mollissima e J. mutabilis as estaminadas duram entre 12 e 15 horas e as pistiladas entre 36 e 48 horas e a abertura é crepuscular. A produção de néctar, a viabilidade...

Autores: Neves,Edinaldo Luz das; Viana,Blandina Felipe.
Highly eusocial bees (Hymenoptera, Apidae) flower visitors in a continental sand dune ecosystem from the medium São Francisco River, Bahia, Brazil. A community of highly eusocial bees in sand dunes, covered with caatinga vegetation, in the medium São Francisco River, Bahia (10º47' 37"S and 42º49' 25"W) was studied. The local climate is semi arid and hot, with mean temperature of 25.7 ºC and annual precipitation of 653.8 mm. Censuses took place every two months, from February to December of 2000. The bees were sampled on flowers with entomological nets, from 6:00 a.m. to 5:00 p.m. A total of 2,147 individuals of eight species of Apinae were found, of which Apis mellifera Linnaeus (40.2%), Trigona spinipes (Fabricius) (28.7%) and Frieseomelitta silvestri...

Comunidade de Euglossini (Hymenoptera, Apidae) das dunas litorâneas do Abaeté, Salvador, Bahia, Brasil
Provedor de dados: 92
Autores: Viana,Blandina Felipe; Kleinert,Astrid Matos Peixoto; Neves,Edinaldo Luz das.
Community of Euglossini (Hymenoptera, Apidae) from the coastal sand dunes of Abaeté, Salvador, Bahia, Brazil. The Euglossini community structure was analyzed by attracting males with the scents eucalyptol, eugenol, vanillin, benzyl benzoate and methyl salicylate, and by netting bees on flowers. The samplings took place three times a month along one year from 6:00 a.m. to 6:00 p.m. The scent baits attracted 670 individuals belonging to seven species of three genus. The predominant species were Euglossa cordata (Linnaeus, 1758) (76.6%) and Eulaema nigrita Lepeletier, 1841 (21.8%). Euglossini males visited the scents along the whole year, being more abundant in May and in August. The most efficient fragrance was eucalyptol, attracting 624 individuals of five...

Uma nova espécie de Euplusia da Bahia, Brasil (Hymenoptera, Apoidea, Euglossinae)
Provedor de dados: 104
Autores: Moure,Jesus Santiago; Neves,Edinaldo Luz das; Viana,Blandina Felipe.
Euplusia aridicola sp. n., a member of the short longued group, is described as a new species. It can be easily recognized by the large white yellowish pubescence on the sides of terga second to fourth, the bright anterior half of mesoscutum covered by yellowish hairs; clypeus medially bicarinate. The holotype was colleted in Ibiraba, Barra, a semi-arid region of Bahia, Brazil, using eucalyptol, as an attractant.

Autores: Neves,Edinaldo Luz das; Viana,Blandina Felipe.
This paper reports the results concerning collection of Euglossinae bees in a mangrove ecosystem in Valença(13º22'08"S and 39º04'20"W), Bahia. These samples were made twice a month, for a year. The chemical baits Citronella, Eucalyptol, Eugenol, Metyl Salicylate and Vanillin attracted 1,144 specimens distributed among twelve species and two genera: Eulaema (Lepeletier, 1841) and Euglossa (Latreille, 1802). The predominam bee species was Eulaema nigrita (Lepeletier, 1841) consisting of 49.4% of the collected specimens, followed by Euglossa cordata (Linnaeus, 1758) with 44.88%, Euglossa imperialis (Cockerell, 1922) with 2.4% and Eulaema meriana flavescens (Friese, 1899) with 1.6%. Theothers species, considering sporadic visitors, Euglossa securigera...

Aspectos da biologia de nidificação de Euplusia mussitans (Fabricius) (Hymenoptera, Apidae, Euglossini)
Provedor de dados: 104
Autores: Viana,Blandina Felipe; Neves,Edinaldo Luz das; Silva,Fabiana Oliveira da.
The architecture and biology of Euplusia mussitans (Fabricius, 1787) nests were investigated, using trap nests made by wood, which were randomly distributed in a fragment of a coastal sand dunes, in Salvador, Bahia. Brazil (12º56'S and 38º21'W). 10 nests were found in cavities with 1.5 cm in diameter. From them emerged 10 females and 16 males (Sex ratio = 0,38). The nest cells were made of small pieces of bark cemented together with resin. The number of cells in the nests varied from 2 to 4, with females cells at the inner end and males cells towards the entrance. No significant difference was observed (t= 0.7274, P &gt; 0.05) between the medium size for males (6.3 mm ± 0.16) and for females (6.4 mm ± 0.29). The development time of females was longer than...

Influence of landscape structure on Euglossini composition in open vegetation environments
Provedor de dados: 49

Abstract The fauna of Euglossini bees is poorly known in savanna regions, making it difficult to understand how these bees use open vegetation environments. The aim of this study was to evaluate the influence of landscape structure on species abundance and composition of Euglossini bees in naturally heterogeneous savanna landscapes. Nine sites were sampled monthly using six traps with chemical baits. Three aromatic essences (eucalyptol, methyl salicylate and vanillin) were used to attract the Euglossini. Surrounding environmental conditions were measured using three independent variables, calculated in multiple scales: index of local vegetation and two landscape indices (Shannon Diversity and area-weighted shape). We compared the competing hypotheses...
