Stingless bees are an important asset to assure plant biodiversity in many natural ecosystems, and fulfill the growing agricultural demand for pollination. However, across developing countries stingless beekeeping remains essentially informal activity, technical knowledge is scarce, management practices lack standardization. Here we profited from large diversity of beekeepers found Brazil assess impact particular on productivity economic revenues commercialization bee products. Our study...
Abstract Functional traits help to understand biological diversity and the mechanism by which ecological communities are structured how they respond environment. For example, high tree species within tropical forests can be grouped into a few functional attributes, wood density, size dependence on animal pollination or seed dispersal. However, little is known about these influence taxonomic in forests. We carried out vegetation census six plots (20 × 100 m) National Forest of Carajás (Amazon...
Pollination may be severely affected by the decreasing size and increasing isolation of habitat patches. However, most studies that have considered effects these two variables on plant-pollinator interactions been carried out in areas undergone anthropogenic fragmentation, little is known about their natural habitats. The Carajás National Forest Campos Ferruginosos Park are protected eastern Amazon where one can find isolated ferruginous outcrops characterized iron-rich soil herbaceous-shrub...
Abstract Aim The objective of this study is to estimate the current potential geographic distribution Plebeia flavocincta and evaluate influence climate on dynamics suitable habitat availability in past future. Location Northeast region Brazil dry forest areas. Methods suitability modeling was based two algorithms, global circulation models, six different scenarios. We used tool areas occurrence (Last Interglacial Last Glacial Maximum), present, future (years 2050 2070). Results According P....
El objetivo de este estudio descriptivo fue analizar la relación entre los ejercicios fuerza y parámetros hematológicos, virológicos antropométricos. Fueron analizadas 40 personas ambos sexos que viven con VIH/SIDA, edades 20 50 años, ciudad Mossoró (Rio Grande do Norte, Brasil). Todas fueron evaluadas antes después ser sometidas a un programa fuerza. Los datos analizados el SPSS 20.0 en su versión portugués. Fue posible encontrar diferencia significativa (p < 0.05) porcentaje grasa, urea...
Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common human enzymopathy. It affects as many 330 million individuals worldwide. This may determine neonatal jaundice, chronic nonspherocytic hemolytic anemia and acute induced by drugs, infections broad bean ingestion. The efficacy of blood transfusion decreased when donor G6PD deficient. In this study, we aimed at determining prevalence in donors Mossoro, Brazil. Samples 714 (576 men 138 women; 343 white 371 non-white) with...
Tropical dry forests are increasingly threatened by human activities. In Northeast Brazil, the Caatinga, an area of tropical surrounded wetlands, is considered globally unique among these habitats. this region, stingless bee Plebeia flavocincta found in a variety environmental, ecological, and demographic conditions. We aimed to characterize P . populations within its natural range through wing geometric morphometrics mitochondrial DNA (mtDNA) analyses. The characterization population...
The present work aims to investigate the floral biology and morphology of one member Calophyllaceae (or Clusiaceae sensu lato), Caraipa grandifolia in Caxiuanã National Forest, eastern Brazilian Amazon identify bioclimatic affinities this species, providing insights about its environmental requirements mapping potential distribution, given paucity data flood-tolerant trees. Nine flowering individuals were located along a 2 km stretch Anapu river, visited by eleven different species (some...
Most studies analyze fragmentation due to habitat loss caused by anthropogenic activities and few of them analyzed on naturally fragmented areas. In the Eastern Amazon, it is possible find areas open surrounded pristine forest. Understanding how species respond isolation in these an important challenge for decision-making processes aiming conservation restoration. Using standardized methods bee collection (entomological nets, bait trap, pan nest trap), objective this study was composition...
Abstract Amphidecta calliomma is a butterfly species that occurs in Colombia, Bolivia, Peru, Venezuela, Ecuador, Panama, and Brazil (in the states of Mato Grosso, Grosso do Sul, Rondônia, Pará). Here, we present new occurrence A . Carajás National Forest (Pará, eastern Amazon), expanding known distribution species. We also provide model comparing contribution to area projections, supporting future field research. The projections reveal an expansion for located mainly southeast portion Amazon...
The stingless bee Melipona fuliginosa Lepeletier is described as being aggressive robber, but there little information about its raids. Here, we describe two different raids of M. on other species: paraensis Ducke and fasciculata Smith. robbing behavior was observed in the Volta Grande do Xingu region (Pará) Carajás National Forest (Pará), attacks by occurred at end dry season, shortly before start rainy a time flower scarcity. raid hive lasted five days involved no deaths worker bees both...
Abstract Bees are important insects both environmentally and economically. Despite this, most bee species poorly characterized regarding their morphology nesting habits, which relevant characteristics for planning management conservation. Plebeia flavocincta is a stingless that occurs in the Northeast region of Brazil there little knowledge about its biology. Here, we morphologically characterize workers from 54 colonies use seven to describe structure species’ nest. All nests were found...
