Abstract With the rising threat to insect pollinators and upcoming pollinator crisis, it is important know how contribute pollen transfer. The contributions of individual taxa transfer depend both on their abundance much each can carry, with overall importance being a multiplication these two values. Here, we quantified load across diverse spectrum variation in over 11 years. We found that, while was relatively small among (compared high variability individuals within taxon), visitation...
Parental care is a behavior that increases the growth and survival of offspring, often at cost to parents' own and/or future reproduction. In this study, we focused on nest guarding, which one most important types extended parental care; studied in two solitary bee species genus Ceratina with social ancestors. We performed experiment removing laying female, who usually guards after completing its provisioning, test effects guarding offspring fate. By dissecting natural nests, found...
Significance Biparental care is a rare strategy of offspring protection in insects. We discovered case biparental bees, Ceratina nigrolabiata . Benefits were identified for both males and females; yet, we found that an extraordinarily high proportion unrelated to guard males. This because females C. are polyandrous store sperm. Therefore, the most important benefit increased mating opportunities. suggest female polyandry prolonged receptivity supported origin and/or maintenance concomitant...
Small carpenter bees in the genus Ceratina are behaviourally diverse, species-rich, and cosmopolitan, with over 370 species a range including all continents except Antarctica. Here, we present first comprehensive phylogeny of based on ultraconserved element (UCE) phylogenomic data, covering total 185 ingroup specimens representing 22 25 current subgenera. Our results support most recognized subgenera as natural groups, but also highlight several groups need taxonomic revision - particularly...
Abstract Biparental care is very rare in insects, and it was well-documented only one bee species to this date – Ceratina nigrolabiata . However, biparental recently discovered species, detailed description of natural history missing. Here, we describe the nesting cycle C. Pairs are established before female starts offspring provisioning. After provisioning finished (when youngest reached larval stage), male abandons nest. Males which present nests where already brood cells, probably mainly...
Generalist pollinators are important in many habitats, but little research has been done on small-scale spatial variation interactions between them and the plants that they visit. Here, using a spatially explicit approach, we examined whether multiple species of flowering occurring within single meadow showed structure their generalist pollinator assemblages. We report results for eight plant which at least 200 individual visits were recorded. found all these species, proportions general...
Animal-pollinated plants face a high risk of pollen loss during its transfer. To limit the negative effect losses by consumption and heterospecific transfer, plant species may adjust stratify their availability day (i.e., "schedule" presentation) attract pollinators in specific time frames.We investigated diurnal patterns pollinator visitation three coflowering species: Succisa pratensis with open flowers accessible pollen, pollinated mainly pollen-feeding hoverflies; Centaurea jacea less...
Abstract Parental care directed to adult offspring is uncommon in animals. Such parental has been documented Xylocopinae bees (Hymenoptera: Apidae). Moreover, some Ceratina (Xylocopinae) are known feed mature siblings, and feeding of siblings achieved by dwarf eldest daughters when mothers died. These intentionally malnourished usually originate from the first brood cell. Here, we examined pattern provided young adults three small European carpenter bees: ( ) cucurbitina , C . Euceratina...
Many organisms are known to have wide distribution ranges, which cover large variability of ecological conditions. Therefore, natural history traits can differ throughout the distributional range, and, thus, studies on from multiple areas a single species highly valuable. Ceratina cucurbitina is most common small carpenter bee in Europe. We examined social status nests and maternal investment four European locations: Czech Republic, Italy, Albania, Crete. This solitary all studied locations....
Abstract Facultatively social insects are an optimal model group for the study of emergence cooperation between individuals. Factors influencing fitness benefits nesting still debated. Nonreproductive subordinates can benefit from indirect due to increasing reproductive success related individuals or direct future reproduction. Here, we studied costs and in small carpenter bee Ceratina albosticta. From demographic data within-nest relatedness, obtained key parameters assessing solitary...
1. Maternal investment can be influenced by several factors, especially maternal quality and possibilities for future reproduction. Mass provisioning Hymenoptera are an excellent group measuring because mothers distribute food sources to each brood cell offspring separately. Generally in aculeate Hymenoptera, larger females produce invest more female than male offspring. 2. This study investigated patterns of Ceratina chalcites , which has uncommon type sexual size dimorphism Hymenoptera: on...
Societies of social Hymenoptera usually consist groups closely related females in which the dominant female(s) is specialized for reproduction and subordinate care immature offspring. Studying simple societies allows identification factors responsible early stages evolution sociality. Here, we examined facultative nesting species Ceratina chalybea using nest dissection, observation nests, evaluation relatedness microsatellite loci. Social nests were composed an old female on average 3.38...
It is increasingly recognised that intraspecific variation in traits, such as morphology, behaviour, or diet both ubiquitous and ecologically important. While many species of predators herbivores are known to display high levels between-individual variation, there a lack studies on pollinators. important fill this gap because individual-level specialisation flower-visiting insects expected affect their efficiency pollinators with consequences for plant reproduction. Accordingly, the aim our...
Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate unfertilized eggs. However, some taxa Hymenoptera have evolved thelytoky, which diploid parthenogenetically In contrast to other hymenopteran lineages, like ants and parasitic wasps, thelytoky generally very rare bees. Here, we evaluated frequency small carpenter bee Ceratina dallatoreana , was previously assumed be thelytokous. By comparing genotypes...
