Summary: This study examines the trait matching/mismatching between flower corolla tube length and pollinator tongue length in Roscoea gingers. It is found that gingers with long corolla tubes in the western Himalayas have pollinators with correspondingly long tongues, but this match is not observed in the eastern Himalayas. The results suggest that pollinators mediate stabilizing selection on the distal portion of the corolla tube and the elevated liquid level of nectar in the distal tube evolved subsequent to dispersal into the eastern Himalayan region and loss of long-tongue pollinators.

Summary: In the context of climate warming, alterations in plant pollination and reproductive success due to increased air temperatures constitute a significant issue. Higher temperatures negatively affect floral traits and rewards, leading to reduced flower visitation by pollinators, which could in turn decrease plant pollination rates and reproductive success under global temperature increases caused by climate change.

Summary: Plant-centred networks showed higher beta-diversity of interactions in space compared to animal-centred networks, with turnover being the main explanatory factor for beta-diversity in both methods. However, rewiring was proportionately more important in the animal-centred method. Plant-centred method indicated lower network modularity and specialization, while floral traits modulated the effects of sampling method on species-level network metrics. Combining animal- and plant-centred approaches returned intermediate values for beta-diversity of interactions and network metrics, suggesting that different methods may be better suited for answering questions at different scales.

Summary: Andromonoecy, the presence of perfect and staminate flowers in the same individual, has evolved repeatedly in angiosperms. The smaller size and higher pollen production of staminate flowers enhance pollination success, even with limited resources.

Summary: The flowering phenology and flower-visiting insects of an alpine site in central Taiwan were investigated. The results showed that bees, flies, and other insects were the main flower visitors, with bees being more associated with seasonal patterns of flowering. The abundance of bumble bees consistently increased as the season progressed, reflecting colony development.

Summary: Weather conditions affect insect activity, and understanding their responses to different environments helps determine the impact of environmental change on plant-pollinator networks. In alpine regions, taxa may be more vulnerable to climate change, with insect orders showing different behaviors in response to environmental conditions.

Summary: The number of open flowers on a plant can affect plant fitness by attracting more pollinators. However, as floral display size increases, the fitness returns are expected to diminish as pollinators tend to visit more flowers per plant consecutively. A study found evidence of increasing pollen production but not ovule production with increasing floral display size in animal-pollinated angiosperms.

Summary: The study on buzz-pollinated flowers reveals a division of labor among different stamen morphs, with large bees mainly exploiting pollen from central anthers, and intermediate stamens attracting both pollinators and providing pollen resources. This division of labor in large pollen flowers is associated with the evolution of trimorphic androecium, representing an effective strategy for overcoming the pollen dilemma and optimizing feeding function.

Summary: The study found that annual and mixed flower fields are most effective in providing abundant food resources, while perennial flower fields provide the poorest foraging habitats. Pollen samples revealed more visited plant species and assessed floral resource use more reliably than direct observations.

Summary: Botanical gardens can provide valuable insights into plant-pollinator interactions. In this study, hoverflies were found to play a significant role in pollen transport networks, particularly in heterogeneous open environments. The findings highlight the importance of understanding plant-pollinator interactions in botanical gardens for ecological management.

Summary: Pollination services from insects are crucial for avocado yield and fruit quality. A study in Kenya found that the Western honey bee and hover fly species were the most efficient pollinators, with the highest pollen deposition and loads. As wild pollinators may be inadequate, managing Western honey bees can ensure sufficient pollination services for avocados.

Summary: Research shows that in hermaphrodite plants, sexual interference between male and female function can be reduced by protandry. Lack of pollinator service in these plants can lead to the restriction of male function, which may lower seed production in comparison to females. This sexual conflict appears to have played a role in the evolution of gynodioecy in certain populations, highlighting the importance of understanding sexual dimorphism in plant evolution.

Summary: This study investigates the intra-inflorescence variation of a perennial herb called Salvia przewalskii and finds that architectural effects play a crucial role in resource allocation within decoupled flowering inflorescences. The study also highlights that inherent floral traits may modify the effect of architectural effects on sex allocation.

Summary: The vertically resolved aerosol chemistry in summer in Beijing has been poorly studied. Measurements were conducted on a meteorological tower, showing that aerosol liquid water played a crucial role in aerosol formation and contributed to higher nitrate concentration in the city aloft. The vertical profiles of organic aerosol factors varied differently, and differences in oxygenated OA between summer and winter were related to photochemical processing.

Summary: This study proposes a mechanical parameter, the bending proof strength (sigma(P,0.005%)), to accurately measure the onset of plastic deformation of BMG sheets. By conducting a series of stepwise cyclic loading-unloading tests, the earlier stage of shear banding for BMG sheets can be timely captured, showing superiority over conventional testing methods.

Summary: This paper describes a new species of the ginger family (Zingiberaceae) named Roscoea stenophylla Y. L. Fan, which is found in Yunnan, China. It bears morphological resemblance to R. schneideriana (Loesener) Cowley in terms of leaf shape, individual size, inflorescence shape, and floral color. However, it can be distinguished from R. schneideriana by its longer and narrower leaves, longer corolla tubes, reflexed labellum, inflated and not hooked stigma, and anther bent into a semicircle (U type) without inflation at the end of the connective spurs.

Summary: Quantifying the extent of ecogeographic isolation in Aquilegia species is crucial for understanding their evolutionary trajectory under climate change. In this study, environmental niche models were used to predict the potential distributions of four closely related Aquilegia species. The investigation revealed significant ecological differentiation among the species, except for A. kansuensis and A. ecalacarata. The current strengths of ecogeographic isolation were found to be above 0.5 in most cases, and the species exhibited expanding ranges in past and future climate scenarios.
