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.

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.

Honey bees play a crucial role in natural ecosystems, mainly through their pollination services. Within hive, they exhibit intricate social behaviors and communicate among thousands of individuals. Accurate detection segmentation honey are for automated behavior analysis, as significantly enhance object tracking recognition by yielding high-quality results. This study is specifically centered on the individual bees, particularly Apis cerana , within hive environment, employing Mask R-CNN deep learning model. We used transfer weights from our previously trained mellifera model explored data preprocessing techniques, such brightness contrast enhancement, to performance. Our proposed approach offers an optimal solution with minimal dataset size computational time while maintaining high Mean average precision (mAP) served evaluation metric both tasks.

To receive the benefits of social living, individuals must make effective group decisions that enable them to achieve behavioural coordination and maintain cohesion. However, heterogeneity in physical environments surrounding decision-making contexts can increase level difficulty organisms face making decisions.

Many bees visit just one flower species during a foraging trip, i.e. they show constancy. Flower constancy is important for plant reproduction but it could lead to an unbalanced diet, especially in biodiversity-depleted landscapes. It assumed that does not reduce dietary diversity social bees, such as honeybees or bumblebees, this has yet been tested. We used computer simulations investigate the effects of on colony diet species-rich and species-poor also explored if communication about food sources, which by many further reduces forage diversity. Our reveal extensive loss owing both environments. Small flower-constant colonies often discovered only 30–50% all available species, thereby increasing risk nutritional deficiencies.

Communication allows members of a collective to share information about their environment. Advanced systems, such as multicellular organisms and social insect colonies, vary in whether they use communication at all and, if do, what types signals use, but the origins these differences are poorly understood. Here, we develop theoretical framework investigate evolution diversity strategies under collective-level selection. We find that can evolve depends on collective's external environment: only evolves sufficiently stable environments, where costs sensing high enough disfavour independent not so optimal strategy is ignore environment altogether. Moreover, diverse signalling strategies-including those relying prolonged (e.g. honeybee waggle dance), persistence ant trail pheromones) brief frequent communicative interactions antennal contacts)-can be explained theoretically terms interplay between demands internal constraints signal. Altogether, provide general for comparing found nature uncover simple ecological principles may contribute diversity.
