The paper shows bumblebee-mimicking hoverflies have shifted flower preference to blue, matching their models' choices, supporting behavioural mimicry.

This study examines how dicamba herbicide drift affects plant-pollinator interactions in weeds, finding reduced pollinator visits and disrupted relationships between flower displays and pollinator behavior.

This study shows that hummingbird-pollinated Costus species lose floral scent through gene downregulation, not pseudogenization, highlighting strong selection pressures for scent loss.

This study shows that small changes in pollen availability timing significantly affect Bombus terrestris colony behavior, development, and reproductive fitness.

The paper tests the impact of adding wildflower patches in urban areas on pollinator communities and pollination services, finding benefits for social bees but not all insect taxa, and an increase in tomato seed set.

This study uses metabarcoding to compare seasonal diets of honeybees and buff-tailed bumblebees in France, finding that primer choice has a greater impact on plant segregation than pollinator species.

This study evaluates using smartphones and time-lapse photography for pollinator monitoring, finding that bees can be identified to genus level but flies are more challenging due to size and features.

This study investigates whether pollinators influence the essential amino acid profiles in nectar by testing bumblebee preferences and finding no direct selection pressure but post-ingestive evaluation mechanisms.

The paper tests reciprocal trait influence in plant-frugivore interactions using generalized joint attribute modeling and finds frugivore traits affect Piper consumption but plant morphological traits do not.

The paper assesses the prevalence and impact of exploitation barriers on network robustness in plant-hummingbird communities using a Bayesian hierarchical model and interaction data.

This study uses the discrete element method to simulate pollen expulsion from vibrating anthers, finding a correlation between anther wall jerk and pollen release rate, and highlighting the role of pollen-pollen interactions.

This study assesses global extinction risks of vertebrate pollinators, finding higher threats to mammals compared to birds and reptiles, with hotspots in specific regions and emphasizing conservation priorities.

The paper estimates the economic value of vertebrate pollination in India, finding bird pollinators contribute more than mammal pollinators, with a total value of £2.86 million.

This study shows that adding six indigenous plant species to an urban greenspace significantly increased indigenous pollinator species and flower-visiting insect diversity.

This study tests Osgood's model of learning by examining how stimulus and response similarity affect memory transfer and interference in bumble bees foraging on artificial flowers.

This study examines how age and sex affect seed dispersal patterns of native and non-native plants by lion-tailed macaques, finding differences in fruit consumption diversity, seed dispersal quantity, and substrate preferences.

This study examines how pollinator interactions with Brassica carinata are affected by managed beehives and neonicotinoid seed treatment, finding that pollination boosts seed set but insecticides harm pollinator health.

This study shows bumble bees consume pollen directly from flowers to assess its quality for the colony, not just for personal nutrition.

This study tests the peak-end rule in bumblebees by comparing their preference for sequences of rewards with and without a disappointing final reward, finding no preference for the sequence with higher total reward.

This study evaluates seed dispersal effectiveness and plant-bird interaction networks in two locations of the Tehuacan Valley, finding that few birds are effective dispersers and plant communities are vulnerable to extinction.

This study compares pollinator communities in coffee agroforestry, monoculture, and tropical rainforest in DR Congo, finding agroforestry less effective than rainforest for pollinator conservation.

This study identifies a novel floral mimicry system where flowers resemble aerial litter, using a monoterpene synthase to attract pollinators.

The paper assesses the attractiveness of municipally-planted decorative plants to pollinators in Regensburg, finding significant variation in insect visitation rates and highlighting opportunities for improving urban forage.

This study examines how glacier retreat affects plant-pollinator network structure and robustness, finding shifts toward generalist interactions and reduced network stability.

The paper investigates floral constancy in bees, finding that they are constant to locally abundant species rather than landscape-wide abundances.

This study shows that sugar syrup feeding increases Honeybee pollen collection from Guizotia abyssinica, enhancing pollination efficiency and potentially crop yield.

The paper investigates how vegetation density in small urban gardens affects insect species richness and diversity, finding vegetation density to be the main driver.

This study shows that bumble bees learn to handle different flower types more quickly, improving pollen collection but not affecting pollen deposition on flowers.

This study shows that managed bees improve coffee yield and quality, increase farmer income, and are not significantly harmed by field-realistic levels of thiamethoxam.

This study expands knowledge of nectar plants used by US butterflies from 25% to 90% of species, providing data to improve conservation strategies and habitat restoration.
