Euglossine bee communities in small forest fragments of the Atlantic Forest, Rio de Janeiro state, southeastern Brazil (Hymenoptera, Apidae)
Aguiar, Willian Moura de;Gaglianone, Maria Cristina;
Revista Brasileira de Entomologia , 2012, DOI: 10.1590/S0085-56262012005000018
Abstract: euglossine bee communities in small forest fragments of the atlantic forest, rio de janeiro state, southeastern brazil (hymenoptera, apidae). euglossine bees are important pollinators in forests and agricultural areas. although the structure of their communities is critically affected by anthropogenic disturbances, little is known about these bees in small forest fragments. the objectives of this study were to analyze the composition, abundance, and diversity of euglossine bee species in nine small fragments of different phytophysiognomies of the atlantic forest in southeastern brazil, and to identify the environmental variables that may be related to the species composition of these communities. males were sampled quarterly from may 2007 to may 2009 with aromatic traps containing methyl cinnamate, vanillin, eucalyptol, benzyl acetate, and methyl salicylate. a total of 1558 males, belonging to 10 species and three genera of euglossina were collected. the richness ranged from five to seven species per fragment. euglossa cordata, e. securigera, eulaema nigrita e e. cingulata were common to all fragments studied. the diversity differed significantly among areas, ranging from h' = 1.04 to h' = 1.65. the precipitation, phytophysiognomy, and altitude had the highest relative importance over the species composition variation. the results presented in this study demonstrate that small forest fragments are able to support populations of euglossine bee species, most of which are widely distributed and reportedly tolerant to open and/or disturbed areas and suggest that the conservation of such areas is important, particularly in areas that are regenerating and in regions with agricultural matrices where these bees can act as important pollinators

Revista Brasileira de Entomologia , 2008, DOI: 10.1590/S0085-56262008000200007
Abstract: this study describes and analyses the behavior of l. lurida flower visitors in fragments of tabuleiro lowland forest. this monoecious species flowered from october to january. the flowers opened between 5:30 and 10:00 a.m. and floral anthesis did not exceed one day. standardizing samples on flowers resulted in 172 bees, belonging to ten genera and 18 species. epicharis flava (42,3%), xylocopa frontalis (16,3%) and eufriesea surinamensis (11,6%) performed the highest relative frequencies, mainly occuring between 7:00 and 11:00a.m. centridini, euglossina and xylocopini bees took nectar on flowers and were considered effective pollinators. megachile collected pollen and also was potential pollinator. oxaea flavescens acted as nectar thief by piercing the flower hood. experiments of spontaneous autopollination indicated no fruit set and low fruit set (0,48%) was observed in flowers under natural conditions. as discussed for other zygomorphic flowers of lecythidaceae, the complex floral morphology restrict visitors to large or robust bees that can get into the flower through the floral hood. nevertheless centridini was the main pollinator group of l. lurida, which differs from the pollinators indicated in other studies on lecythidaceae in the amazonian region.

Abstract: this work aimed at describing and analyzing structural and temporal parameters of communities of euglossina in remnants of lowland forest on tertiary tabuleiro in the north rio de janeiro state in areas with different conservation status and anthropic influences. chemical bait traps were installed from november/04 to november/05, from 8 am to 3 pm, in two sub-areas (burned and preserved) of mata do carv?o (1053 ha) and mata do funil (135 ha). we collected 2,060 individuals of 11 species distributed in three genera in the burned sub-area, 894 individuals of nine species and three genera in the preserved sub-area and 1,115 individuals of 10 species distributed in four genera in mata do funil. the composition of species did not differ among the areas (mrpp, a = -0.015; p = 0.71). the diversity (h?) obtained in the sub-area burned (h? = 1.14) and preserved (h? = 1.12) was significantly higher than that described for mata do funil (h? = 0.98). two peaks of abundance were observed, the larger one in the dry season. great dominance of euglosssa cordata (l.) (d = 0, 54) was observed in the sub-area burned and of eulaema nigrita lepeletier (d = 0, 55) in mata do funil; both species were favored for open or disturbed environments. the smaller fragment presented the lowest value of diversity, suggesting the effect of the lost of area on the community of euglossina. moreover, disturbed areas (burned) can be benefited if in connection with areas in better preservation condition.

Abstract: This article will outline a process of research-intervention carried out over a year in a Psychosocial Care Center forAlcohol and Drugs (CAPSad). This research took place on practices based on concepts that involve the InstitutionalAnalysis, thus advocating a job analysis of the complex network of knowledge and power relations present in suchservice, as well as of the institutional dynamics which causes productive or instituting forces to circulate there, inaddition to forces which tend to perpetuate themselves to what is established. We have used the method ofresearch-intervention, for it is a method of research which dissociates the act of researching from the act ofintervening, causing the route of this research to be traced in the processuality and complexity of the eventsinvestigated. In this investigative-intervening process, the clinic of the Damage Reduction became an issue, for it isa guideline for the public policies in this area.This article will outline a process of research-intervention carried out over a year in a Psychosocial Care Center forAlcohol and Drugs (CAPSad).

Abstract: the euglossine bee community was sampled with chemical bait traps throughout 12 months (november 2004 to october 2005) in five remnants of submontane atlantic forest in s?o jo?o river basin, in the north of rio de janeiro state with different sizes and degradation levels: reserva biológica uni?o (3126 ha), andorinhas (145 ha), imbaú (130 ha), estreito (21 ha) e afetiva (19 ha). 4094 individuals belonging to 17 species of three genera (euglossa, eulaema and exaerete) were captured. the species with highest values of relative abundance were euglossa cordata (linnaeus, 1758), eulaema cingulata (fabricius, 1804), eulaema nigrita lepeletier, 1841 and euglossa sapphirina moure, 1968, the last one being more important in the smaller remnants. among the collected species euglossa analis westwood, 1840 is suggested as possible indicator of preserved forests. comparing the five areas, positive and significant correlations were observed, bee species richness with area size and bee diversity (h') with floristic diversity (h'). these results suggest that losses in forest size and habitat quality influence euglossine bee communities negatively by reducing the abundance and richness of species. the highest similarity values were observed in the imbaú region remnants, distant from each other by up to 2 km, suggesting that these areas are not isolated for euglossine populations, or they have been suffering similar fragmentation effects.

Abstract: the cis ? trans isomerization of the d8 square planar [pt(cl)(sncl3)(ph3)2 ] compound was investigated at the mp4(sdq)//mp2 level of theory. the optimized structures located on the gas-phase potential energy surface indicate that this reaction proceeds through a quasi-tetrahedral transition state. the influence of electronic effects of the ligands on the reaction mechanism was investigated with the charge decomposition analysis (cda) method, which gave support to understand the strong trans effect of the sncl3 ligand. the solvent effect on the gas phase energy reaction was evaluated using the scrf and ipcm continuum models. in both cases, an increase on the energy barrier for the process was observed and, the thermodynamical stability of the cis and trans isomers was changed upon solvation.
