Pollen and bee bread: exploratory study of proximal composition, ability to deactivate reactive species bioaccessibility Bee bread is a natural food produced after various biochemical reactions bee-collected honeybee pollen from the Apis mellifera species, which occur over course seven days, including lactic fermentation.Rich in essential amino acids, fatty simple sugars, proteins, as well immune system booster, it considered functional because presents several bioactive properties, such antioxidant activity.The present aimed obtain better understanding nutritional potential given limited existing knowledge.It evaluated proximate composition Brazilian samples state Paraná, activity by assessing oxygen (ROS), phenolic vitro digestion, epithelial transport compounds Caco-2 cells.In presented 53% total reducing 15% 2% lipids, 19% moisture, 1% ash, while 49% 25% 18% ash.The content undigested extract was 165 mg GAE/g, digested fraction 146 transported 69 120 114 51 GAE/g.It found that have similar physicochemical characteristics; however, showed high value compounds, supporting classification "functional foods" positively contributing human health.

Insights fromMelipona bicolorhybrid genome assembly: A stingless bee genome with chromosome-level scaffold

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2023, Volume and Issue: unknown

Published: Oct. 10, 2023

Abstract Background The highly eusocial stingless bees are crucial pollinators of native and agricultural ecosystems. Nevertheless, genomic studies within this bee tribe remain scarce. We present the genome assembly Melipona bicolo r. This is a remarkable exception to typical single-queen colony structure, since in species, multiple queens may coexist share reproductive duties, resulting genetically diverse colonies with weak kinship connections. As only known genuinely polygynous bee, M. bicolor ’s provides valuable resource for investigating sociality beyond kin selection. Results was assembled employing hybrid approach combining short long reads, 241 contigs spanning 259 Mb (N50 6.2 97.5% complete BUSCOs). Comparative analyses shed light on some evolutionary aspects genomics, including chromosomal rearrangements . Additionally, we explored evolution venom genes other bees, revealing that, apart from two genes, conserved repertoire components remains under purifying selection clade. Conclusion study advances our understanding contributing conservation efforts these vital offering insights into mechanisms driving their unique adaptations.

Extensive loss of forage diversity in social bees due to flower constancy and communication in simulated environments

bioRxiv (Cold Spring Harbor Laboratory), Journal Year: 2023, Volume and Issue: unknown

Published: Nov. 2, 2023

Abstract Bees require a diverse diet for healthy development. Many bee species show flower constancy, that is, they visit flowers of just one during foraging trip. Flower constancy is important plant reproduction, but it could impair dietary diversity in bees, especially biodiversity-depleted, human-modified landscapes. It assumed does not lower social such as honey bees or bumble because different colony members can specialise on species. However, this has never been tested. We used computer simulations to investigate the effects species-rich and species-poor also explored if communication about food sources, which many further reduces forage diversity. Our reveal an extensive loss due both environments. Small colonies often discovered only 30-50% all available species, thereby increasing risk nutritional deficiencies. simulation results explain why have small sizes, are less constant than stingless larger sizes. Remarkably, when communicated Simpson’s , measures evenness visits, approached near zero Finally, we found source clustering, habitat fragmentation impaired These findings help design landscapes increase improve nutrition health

What Makes Them Masters of Survival? Unraveling the Intricacies of Adaptive Thrive of Tetragonula iridipennis Smith in the Dynamic Ecosystems of Tamil Nadu, India

Sociobiology, Journal Year: 2024, Volume and Issue: 71(3), P. e10576 - e10576

Published: Aug. 16, 2024

Stingless bees (Hymenoptera: Apidae), commonly called ‘Dammar in India,’ inhabit concealed environments across various ecosystems. They possess significant ecological importance as ‘Keystone Pollinators’, contributing crucially to the pollination of diverse flowering plants. Increased attention is being given patterning aspects nests nature. Our investigation into this occurrence within human-inhabited characterized by repeated spatio-temporal patterns. Various criteria, including habitat preference, nesting pattern, orientations, elevation, and nest architecture, were chosen assess preferences an indigenous stingless bee, Tetragonula iridipennis Smith, at 30 different locations Tamil Nadu, India. Most colonies inhabited walls (50.0%), followed tree trunks (33.33%). The maximum height entrances from ground level, a parameter for adaptive defense patterns, ranged 1.3 m 2.98 m. Additionally, circumference varied 1.29 cm 2.45 cm. length external tube 1.1 3.24 cm, playing crucial role presenting thin layer mud capping prevent entry intruders. Bees can effectively thwart threats predators Through complex resin coating, pillar-like batumen structures, waxy solid buildings, multiple entrances. Thus, population their colony propagation could be sustained.
