Summary Cocoa is an important agricultural product that plays a crucial role in local communities South America. In Brazil, it traditionally grown agroforestry systems, which are more sustainable and contribute to biodiversity conservation. However, the recent expansion of intensive monocultures tropical forests poses significant threats this activity. Using historical data on land use cocoa productivity at municipality level from Brazil’s primary cocoa-producing states, we show maintaining...
Brazil has the highest biodiversity of native stingless bees in world. However, Brazilian regulations are based on protocols standardized by Organization for Economic Cooperation and Development (OECD), which uses Apis mellifera as a model organism. The safety use an exotic species substitute is problem that concerns members academy government agencies responsible studies this nature neotropical regions where there occurrences bee species. Regarding exposure larvae to pesticides, several...
Wing geometric morphometrics has been applied to honey bees (Apis mellifera) in identification of evolutionary lineages or subspecies and, a lesser extent, assessing genetic structure within subspecies. Due bias the production sterile females (workers) colony, most studies have used workers leaving males (drones) as neglected group. However, considering their importance reproductive individuals, use drones should be incorporated these analyses order better understand diversity patterns and...
Abstract Determining bee flight capacity is crucial for developing management strategies conservation and/or crop pollination and purposes. In this study, we determined the distance of stingless Melipona fasciculata using radiofrequency identification (RFID) technology. For this, conducted two translocation experiments workers equipped with RFID microsensors: (1) release bees at seven distances between 100 3000 m from experimental colonies in Belém, Brazil, (2) six 1500 10,000 Carajás...
Differences in the timing of exoskeleton melanization and sclerotization are evident when comparing eusocial solitary bees. This cuticular maturation heterochrony may be associated with life style, considering that bees remain protected inside nest for many days after emergence, while immediately start outside activities. To address this issue, we characterized gene expression using large-scale RNA sequencing (RNA-seq), quantified hydrocarbon (CHC) through gas chromatography-mass...
Abstract Bee flight capacity determines the area that a colony can exploit, and this knowledge is essential to formulate management conservation strategies for each species. In study, we evaluated of Melipona seminigra using radio frequency identification (RFID). Three questions were addressed: Do RFID tags affect M. workers? What effect landscape on foraging activity? Does time since was re-established range foragers? Our results indicate tag used does not ability . Bees marked with...
Identifying and classifying species of stingless Neotropical bees is not a trivial task requires the help taxonomists substantial study training time. Also, there lack taxonomically useful characters to differentiate among megadiverse group bees, recognize variation. Based on that, we have been testing alternatives character-based, efficient taxonomic determination herein performed exploratory analyses wing shape variation using geometric morphometrics. Thus, built data set photographs right...
O objetivo deste trabalho foi avaliar o efeito de diferentes tipos polinização sobre a qualidade frutos cultivares morangueiro e sua contribuição isolada para massa dos frutos, bem como determinar potencial Plebeia nigriceps (Hymenoptera: Apidae, Meliponini) agente polinizador em ambiente protegido. As Aromas, Diamante Cegnidarem foram submetidas tratamentos com autopolinização, por P. livre. Os experimentos conduzidos estufa tipo pampeana, coberta polietileno transparente desprovida telas...
Scaura Schwarz, 1938 is a small Neotropical genus of stingless bees widely distributed in Brazil. The new species widespread species, and its wide distribution may suggest that it complex. In order to differentiate populations could compose cryptic we studied the wing venation variation using geometric morphometrics 56 workers, 23 these from remaining Atlantic Forest Ceará state 33 Amazon region. Bees differed region, corresponding 38.05% total (principal components analysis), 100% canonical...
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...
O estudo abordou a complexa relação entre crise ambiental e saúde, enfatizando o papel dos profissionais de saúde na promoção da sustentabilidade. Através uma revisão abrangente literatura, foram identificados vários estudos que destacam interconexão meio ambiente humana. Embora tenham sido observados progressos, pesquisa ressaltou lacuna significativa publicações nessa área, sublinhando necessidade urgente maior engajamento para abordar essa questão crucial. Os resultados revelaram...
Tetragona Lepeletier & Serville, 1828 (Hymenoptera: Apidae) is a genus of stingless bees widely distributed in Brazil. It has 15 species the Neotropics, from Mexico to Uruguay, nine which are found However, elongata (Lepeletier 1828), known only Southeast region and had been synonymized with clavipes (Fabricius, 1804), was revalidated without any justification. The aim this study test whether morphometrics analysis wings efficient diagnosis genus, addition testing validity revalidation...

The study of M. subnitida, stingless bee well adapted to extreme environmental conditions, is noteworthy once the Northeastern Brazil faces climate changing predictions in which precipitation rates are expected decrease, and average temperatures increase. well-studied populations limited Caatinga biome, where species was considered endemic. However, occurrence this has been reported contrasting environments from arid region, such as mangrove sandbanks Maranhão state. Our primary goal...
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...
Abordagens de inteligência artificial, como visão computacional, podem ajudar a entender melhor o comportamento abelhas e no seu manejo. Detectar espécies em campo é ainda um desafio para os métodos tradicionais. Neste trabalho, propõe-se uso do detector YOLO justificado por sua capacidade, velocidade generalização. Foi possível detectar grande maioria das presentes nos frames, com mAP 99,5% eficácia.
