“…The ocean is probably a significant barrier preventing gene flow between Ilha Grande and Ilha de São Sebastião and the mainland. Among the islands visited, only Ilha do Mel (Zanella, ), Ilha de Santa Catarina (Steiner et al ., ), and Ilha Grande (Lorenzon et al ., ) had been previously surveyed for bees, and T. angustula was reported on all of them. In our survey we did not locate T. angustula on 6 of the 11 islands we visited.…”

Tetragonisca angustula is one of the most widespread stingless bees in the Neotropics. This species swarms frequently and is extremely successful in urban environments. In addition, it is one of the most popular stingless bee species for beekeeping in Latin America, so nest transportation and trading is common. Nest transportation can change the genetic structure of the host population, reducing inbreeding and increasing homogenization. Here, we evaluate the genetic structure of 17 geographic populations of T. angustula in southern Brazil to quantify the level of genetic differentiation between populations. Analyses were conducted on partially sequenced mitochondrial genes and 11 microsatellite loci of 1002 workers from 457 sites distributed on the mainland and on 3 islands. Our results show that T. angustula populations are highly differentiated as demonstrated by mitochondrial DNA (mtDNA) and microsatellite markers. Of 73 haplotypes, 67 were population-specific. MtDNA diversity was low in 9 populations but microsatellite diversity was moderate to high in all populations. Microsatellite data suggest 10 genetic clusters and low level of gene flow throughout the studied area. However, physical barriers, such as rivers and mountain ranges, or the presence or absence of forest appear to be unrelated to population clusters. Factors such as low dispersal, different ecological conditions, and isolation by distance are most likely shaping the population structure of this species. Thus far, nest transportation has not influenced the general population structure in the studied area. However, due to the genetic structure we found, we recommend that nest transportation should only occur within and between populations that are genetically similar.

“…Among the four regions only one (Ilha Grande), as an insular region, belongs to an environmental protection unit. This choice was strategic as it is a high population of T. angustula has been reported before (Lorenzon et al 2006), a condition which was not known for the other regions. All the studied regions lie in the Atlantic Rainforest morphoclimatic domain (Ab'Sáber 1977) and largely with a closed canopy forest (Dense Ombrophilous Forest), a secondary growth forest, greenlands, mangrove, salt marsh and beach vegetation.…”

The stingless bees are important flowers visitors of several plant species, due to their feeding habits and foraging behavior, constituting an important group to maintain biodiversity and the dynamics of tropical communities. Among stingless bees, Tetragonisca angustula is widely distributed in tropical habitats, and has been considered an important pollinator of different plant families. To support a rational economic use of this group, there is a need to characterize the plant species that represent important sources as part of their diet, as preferred, alternative or casual food sources. The aim of this survey was to distinguish the plant species that T. angustula visited most often. The study was undertaken in four regions of the Atlantic Rainforest in Rio de Janeiro state (Brazil) over a year from March 2008 to February 2009. For this, we collected bees, flowering plants and bee pollen loads from the four sites, and evaluated pollen morphology in the laboratory. Field observations showed the presence of plants belonging to ten different families and pollen loads showed the presence of pollen types belonging to 26 plant families. There were strong differences between pollen types, especially regarding pollen grain shape. The present survey suggests a high value of these plant species as trophic resources for the T. angustula in the understory of Atlantic Rainforest. Changes in these fragments of this forest may compromise the availability of resources for Tetragonisca angustula species and other stingless bees. Rev. Biol. Trop. 60 (4): 1491-1501.

ABSTRACT(Pollen used by Tetragonisca angustula Latreille (Apidae: Meliponina)). Th e objective of this study was to quantify and evaluate the pollen load, which was classifi ed by color, found on Tetragonisca angustula Latreille (Apidae: Meliponina). Eighteen pollen types, belonging to 16 plant families, were found on T. angustula. Th e majority of the pollen, from diff erent species, was yellow, indicating that T. angustula prefers this color. Th is was followed by brown pollen and then pumpkin colored pollen. Th e pollen grains that were light colored were the most common. Th e more frequent pollen types were Meliaceae, Myrtaceae (Eucalyptus spp.), Piper mollicomum (Piperaceae), Schizolobium parahyba (Caesalpiniaceae) and Tibouchina granulosa (Melastomataceae).
