“…When compared to the fauna of Euglossini in the semideciduous forest in the north of the state of Paraná, the greater diversity found is due to the uniformity in abundance of species found than the richness obtained (Sofia & Suzuki 2004). Studies carried out in various localities in Brazil reveal that the Shannon-Wiener diversity index calculated for the communities of Euglossini shows a variation between 0.22 and 2.57, with the Amazon Forest being the region with greatest richness and diversity (Silva et al 2009). A comparison of diversity indices should also take into account the methods of capture.…”

The effect of habitat fragmentation on the structure of orchid bee communities was analyzed by the investigation of the existence of a spatial structure in the richness and abundance of Euglossini species and by determining the relationship between these data and environmental factors. The surveys were carried out in four different forest fragments and one university campus. Richness, abundance, and diversity of species were analyzed in relation to abiotic (size of the area, extent of the perimeter, perimeter/area ratio, and shape index) and biotic characteristics (vegetation index of the fragment and of the matrix of each of the locations studied). We observed a highly significant positive correlation between the diversity index and the vegetation index of the fragment, landscape and shape index. Our analysis demonstrated that the observed variation could be explained mainly by the vegetation index and the size of the fragment. Variations in relative abundance showed a tendency toward an aggregated spatial distribution between the fragments studied, as well as between the sampling stations within the same habitat, demonstrating the existence of a spatial structure on a small scale in the populations of Euglossini. This distribution will determine the composition of species that coexist in the area after fragmentation. These data help in understanding the differences and similarities in the structure of communities of Euglossini resulting from forest fragmentation.

“…Rebelo and Cabral (1997) made similar reports for the Brazilian savanna, and Oliveira (1999) for the Amazon forest. Orchid bees abundance peaks in the rainy season have been recorded in several types of vegetation, such as Atlantic forest (Rebêlo & Garófalo, 1997;Ramalho et al, 2009), savanna (Brito & Rego, 2001), sandbank coastal vegetation ("restinga") (Viana et al, 2002;Silva et al, 2009), and xerophilous vegetation ("caatinga") (Andrade-Silva et al, 2012).…”

To investigate species composition, diversity, richness, and monthly abundance of orchid bees in different types of dense rainforest, placed in different altitudes, the orchid bees were collected for 11 months in three vegetation types: dense montane ombrophilous forest (DMOF), dense submontane ombrophilous forest (DSOF, with two sites points), and dense lowland ombrophilous forest (DLOF). Were collected 1,945 males of 20 species using aromatic traps. The DMOF showed the highest species richness (19), and diversity (H’ = 2.42) , whereas the DSOF_1 showed the highest abundance (775). Euglossa cordata (Linnaeus) was the most abundant species in three areas, and Euglossa ignita Smith was the most abundant species in the DSOF_2 . Abiotic factors were correlated with some community parameters. Our study reveals the importance of preserving different phytophysiognomies within the same biome to conserve orchid bees.

“…Oliveira et al (2016) evaluating the flowering periods of Mouriri guianensis (Melastomataceae) and the interaction with crepuscular bees highlighted the importance of these bees for the pollination of this plant species, detaching 86 individuals performing crepuscular visits. The maintenance of the structural sandbank mosaic is essential for the preservation of these bees' populations, of their function in the plant community reproduction and in the ecosystem processes (Silva et al, 2009). Azevedo et al (2010) inventorying the Phlebotomine communities in São Luís Island and the city of São José de Ribamar, sampled 24 species in five of dense fragments of forest.…”

Maranhão North Mesoregion has the highest demographic density of the state because where is located the capital, São Luís. The climate is humid or sub-humid tropical with rainfall rates around 1,000 mm / year, and suffering, this way, the mass influence of air. The coastal plain of Maranhão is subdivided into four geomorphological sectors: to the west-northwest coast, which is marked by State recesses, specifically maranhense Golfão; the east coast where dominate the fields of movable or fixed dunes; and the deltaic plain of the Parnaíba River. This study aimed to present a panorama of the North region of Maranhão State demographic density focus, economic sectors, and biological diversity. With regard to the economic sector, the northern region, one of the highlights are the Lençóis maranhenses, the main geo-touristic attractive in relation to its natural beauty and to its mysteries, rivers, mangroves, moving dunes and interdune lagoons, constituting areas of magnificent landscapes, with favorable conditions for recreational tourism. In the extreme north of the state, is found the baixada maranhense that is considered one of the most beautiful state tourist centers, characterized by extensive plains, rivers, estuaries, mangroves and flooded fields, having as highlight, the floating islands of Formoso, Lontra, Cajari and Capivari lakes, in the city of Penalva. In terms of biological diversity, the North Region is dominated by the Amazon forest, which has specific characteristics of the tropical forest. The fauna of the region is typical, with the presence of large and medium-sized animals and many arthropods already reported to the state. The vegetation comprises trees of the Amazon domain, however, is easily found plants of the cerrado biome and babassu palms. In general, the region stands out for its natural beauty and constitute an important economic center. Key words: São Luís Island, Maranhense Amazon, Maranhão State. DIVERSIDADE BIOGEOGRÁFICA DA MESORREGIÃO NORTE DO ESTADO DO MARANHÃO (BRASIL)RESUMO: A Mesorregião do Norte Maranhense possui a maior densidade demográfica do Estado, pois é onde está localizado a capital, São Luís. O clima da região é tropical úmido ou subúmido com índices de precipitação entorno de 1.000 mm/ano, sofrendo assim influência de massas de ar. A Planície Costeira do Maranhão é subdividida em quatro setores geomorfológicos: a costa oeste-noroeste que é marcada por reentrâncias do Estado, especificamente o Golfão maranhense; a costa leste onde predomina os campos de dunas móveis ou fixas; e a planície deltaica do rio Parnaíba. Neste trabalho objetivou apresentar um panorama da região norte do Estado do Maranhão com enfoque densidade demográfica, setores econômicos e diversidade biológica. No que tange ao setor econômico a região norte, um dos destaques é os Lençóis maranhense, principal atrativo geoturístico no que se refere às suas belezas naturais e aos seus mistérios, rios, mangues, dunas móveis e lagoas interdunas, constituindo áreas de paisagens magníficas, com condiçõ...
