Abstract:
... Conditions experienced early in development can affect the future performance of individuals and populations. Demographic theories predict persistent population impacts of past resources, but few studies have experimentally tested such carry‐over effects across generations or cohorts. We used bumble bees to test whether resource timing had persistent effects on within‐colony dynamics over sequenti ...

Abstract:
... Pollination is a key ecological function of most terrestrial ecosystems. Decades of research on single‐trophic‐level communities, particularly plant communities, have helped to build the foundation of diversity–function theory. Yet as it stands, this theory appears to be less useful for intertrophic‐level functions such as pollination, as evidenced by empirical findings that are often inconsistent ...

Abstract:
... Fire is a frequent disturbance in most grasslands around the world, being key for the structure and dynamics of the biodiversity in such ecosystems. While grassland species may be resilient, little is known on how plant–pollinator networks reassemble after fire. Here, we investigate the structure and dynamics of plant–pollinator networks and the variation in species roles over a 2-year post-fire c ...

Abstract:
... Natural pollination of Vanilla species remains poorly understood. Our research aimed at better understanding the pollinator attraction mechanism of the Neotropical species Vanilla pompona. Based on our results, we hypothesize that the identified pollinator Eulaema cingulata is attracted via a dual mechanism combining floral fragrance rewards and food deception.

Abstract:
... Floral constancy of foraging bees influences plant reproduction. Constancy as observed in nature arises from at least four distinct mechanisms frequently confounded in the literature: context-independent preferences for particular plant species, preferential visitation to the same species as the previous plant visited (simple constancy), the spatial arrangement of plants, and the relative abundanc ...

Abstract:
... In response to unfavorable environmental conditions, some Drosera species in the northern hemisphere do not open their flowers but form bud‐like flowers. The bud‐like flowers exhibit pseudo‐cleistogamous behavior and produce similar numbers of seeds as open flowers. However, it is not clear how common this type of reproduction is in the genus Drosera. In this study, we examined the effects of flow ...

Abstract:
... Since the production of large and conspicuous flowers can be costly, self‐pollinated or asexually reproducing plants are expected to lose characters for pollinator attraction. However, some plants still produce conspicuous flowers despite not relying on pollinators for fertilization, suggesting overlooked benefits of receiving flower visitors. Here, we present visitor‐mediated microbial dispersal ...

The “pyrodiversity hypothesis”, which postulates that biodiversity will increase as fire diversity increases, remains largely untested for pollinators, a group of high conservation concern. We tested the relationship between pollinator diversity and pyrodiversity ...

Abstract:
... In most species of Melastomataceae pollen is the only reward for pollinators. Pollen is locked within poricidal anthers and is only legitimately removed by bees that specifically buzz the anthers. Stamen appendages in many species of plants are morphological adaptations of the androecium for pollination, and are evident in several species of Melastomataceae. In an experimental study, anthers with ...

Abstract:
... Pollination is essential for ecosystem functioning, yet our understanding of the empirical consequences of species loss for plant–pollinator interactions remains limited. It is hypothesized that the loss of abundant and generalized (well‐connected) species from a pollination network will have a large effect on the remaining species and their interactions. However, to date, relatively few studies h ...

Abstract:
... MAIN CONCLUSION: Elevated temperatures suppress cell division in developing petunia buds leading to smaller flowers, mediated by ABA. Flower size is one of the most important showy traits in determining pollinator attraction, and a central factor determining the quality of floricultural products. Whereas the adverse effects of elevated temperatures on showy traits have been described in detail, it ...

Enhancing the diversity of mass‐flowering crops (i.e. crop diversity) in agricultural landscapes is often proposed as a measure to favour pollinators and pollination, but it is uncertain whether crop diversity enhances pollinator richness on the wide landscape level. Here, we surveyed pollinator communities in semi‐natural habitats and mass‐flowering crops throughout the whole growing season in 26 ...

However, it is not known to what extent small urban prairies can sustain the plant-pollinator interactions that are vital to both the insects and the plants. The goal of our research was to examine plant/pollinator interactio ...

Abstract:
... Flowering plants provide critical resources for wild bees. Consequently, enhancing flowering plant communities through hedgerows or flower strips has become a common recommendation to support native pollinator populations. Meta-analysis finds that enhancements are associated with higher local bee diversity. However, many studies have also examined the impacts of unmanipulated (i.e., existing, natu ...
